    Sanitary conditions are essential for the production of meals and control of the presence of pathogensis important to guarantee the health of customers. The aim of this study was to evaluate the sanitary quality of food services by checking the presence of thermotolerant coliforms, Staphylococcus sp. and evaluate the toxigenic potential from the latter. The analysis was performed on water, surfaces, equipment, ready-to-eat foods, hands and nasal cavity of handlers in seven food services. The water used in food services proved to be suitable for the production of meals. Most food, equipment and surfaces showed poor sanitary conditions due to the presence of thermotolerant coliforms (60.6%). Twenty-six Staphylococcus species were identified from the 121 Staphylococcus isolates tested. Staphylococci coagulase-negative species were predominant in the foods, equipment and surfaces. In food handlers and foods, the predominant species was Staphylococcus epidermidis. Twelve different genotypes were found after PCR for the classical enterotoxin genes. The seb gene (19.8%) was the most prevalent among all Staphylococcus sp. Both coagulase-positive and coagulase-negative Staphylococci showed some of the genes of the enterotoxins tested. We conclude that there are hygienic and sanitary deficiencies in the food services analyzed. Although coagulase-positive Staphylococci have not been present in foods there is a wide dispersion of enterotoxigenic coagulase-negative Staphylococci in the environment and in the foods analyzed, indicating a risk to consumer health.

    Sanitary and nutritional control of meals distributed by school catering services is one of the institutional duties of the Food Hygiene and Nutrition Services (Servizi Igiene Alimenti e Nutrizione - SIAN) of the Local Health Units. In order to carry out this activity properly it is necessary to ask oneself beforehand what the main outcome of control activities should be. The answer to this question can only be that "proper nutrition is essential for healthy growth". Starting from this assumption, control activities performed along the entire chain of the scholastic catering service, starting from the final dish served at school up to the primary producer, were reviewed. The review was carried out by a team of multiprofessionals which included a physician, a prevention technician, a dietician, a biologist, an agronomist and a veterinarian. Preliminary results are extremely positive and show that the multidisciplinary integration of roles entrusted to the coordinators of SIAN is crucial to obtaining the best results.

    Because of fast-growing demand, export markets can absorb high value added products and offer high returns; for many developing countries export market development is thus a key requirement for rural income generation and rural growth. Although developing countries face increasingly strict sanitary and phytosanitary standards in their export markets, they can maintain and improve market access--and improve domestic food safety and agricultural productivity--by adopting a strategic approach to food safety, agricultural health and trade. High-income countries should increase development flows to help developing countries build the capacity to plan and execute the necessary strategies. The first proposal in this paper is to make two existing sets of guidelines widely available to interested parties, in particular through the World Bank and the World Organisation for Animal Health (OIE). The first covers the broad process of problem assessment, strategy development and action plan formulation; the second set deals with institutional analysis and training of staff of the official sanitary control services. The second proposal is that interested countries and donors should speed up the ongoing development of guidelines, computer software tools and training material to help countries quantify the importance and impact of food safety issues. The focus here is on a 'multipurpose agricultural data analysis and modelization system'. The third proposal is to carry out a case study to help demonstrate that a number of animal health issues related to food safety should be treated as relating to 'global public goods' and thus require intervention on a global scale. Possible candidates are foot and mouth disease and highly pathogenic avian influenza.

    The objective of this study was to evaluate the presence of hygienic and sanitary indicator microorganisms in samples of food served in public schools in Porto Alegre. All the food served in the meal of the session visited was analyzed for Escherichia coli, coagulase-positive Staphylococcus, Salmonella sp. and Shigella sp. Of the total of 196 food products analyzed in 120 schools, 4 contained and Escherichia coli score above the permitted level, and 2 contained coagulase-positive Staphylococcus. Neither Shigella nor Salmonella genus were detected. In the majority of schools studied, it was found that food was of an adequate hygienic-sanitary standard. However, only municipal schools had the supervision of a technician responsible for school food. In the state schools, 60% had never been visited by a nutritionist and in these schools several procedures failed to comply with legal requirements. In most of the schools studied, the food served to students was within adequate standards, though the problems detected revealed the need for the implementation of Best Practices in the school environment.

    The U.S. Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago regulate flows through control structures along the Lake Michigan lakefront and the Chicago Sanitary and Ship Canal (CSSC) for Lake Michigan diversion accounting, flood control, sanitary, and navigation purposes. This report documents the measurement and computation of flow through the Lockport Controlling Works (LCW) and the Lockport Powerhouse. This analysis aided in evaluation of the ratings at both structures, and the development of new ratings at the controlling works. The LCW structure consists of seven 30-feet (ft) wide sluice gates and is used to divert water from the CSSC and into the Des Plaines River. The flow regimes for the sluice gate included both free and submerged weir. Forty and 491 flow values from U.S. Geological Survey streamflow-gaging stations were used to develop equations describing free- and submerged-weir flow, respectively, through the sluice gates. The equations were developed for canal headwater elevations ranging from -7.0 to -10.5 ft Chicago City Datum (CCD), and tailwater (Des Plaines River at Lockport) to headwater (CSSC-LCW-Base) ratios ranging from 0.31 to 0.66. The Lockport Powerhouse structure consists of nine 9-ft wide by 14-ft high sluice gates and two 10-ft diameter turbines. Both tailwater and no-tailwater effect flow regimes occurred during nine measurements. Also, the canal headwater elevations ranged from -2.74 to -8.45 ft CCD, and the gates were configured six different ways during the measurements.

    This work is carried out in Veracruz State covering over 11 jurisdictions of the State (Panuco, Tuxpan, Poza Rica, Martinez de la Torre, Xalapa, Cordoba, Orizaba, Veracruz, Cosamaloapan, San Andres Tuxtla and Coatzacoalcos). The sampling was realized in a period from 2009 to 2013 analyzing home drinking water, supply sources and wells, the sampling was done by the sanitary checkers of different jurisdictions with approved methods and the methodology was validated at the State Laboratory of Public Health. 1637 samples were analyzed by counting equipment Tennelec Canberra series 5 and a gas supply system P-10 with calibration curves for alpha and gross beta. The results of measurements ranging from 0.07 to 0.25 Bq/L in the activity concentration gross alpha annual average, an gross beta were from 0.12 to 0.17 Bq/L in the activity concentration gross beta annual average, and with a concentration range of alpha activity up to 0.62 and a minimum 0.02, and the concentration of beta activity of a maximum value 1.54 and a minimum 0.02, taking also as resulted in five years of analysis only 1.16% of the analyzed samples (19 samples) showed a value of alpha activity concentration above the minimum detectable concentration and 62.43% (1022 samples) of the analyzed samples showed a value of beta activity concentration above the minimum detectable concentration, is also clear that the results of the sanitary jurisdictions of Panuco and Tuxpan not have corresponding activity values for the years 2009, 2011-2013 except 2010. We can conclude that the regular measurements of alpha and gross beta activity in water are invaluable for timely detection of radioactive contamination. (Author)

  18. New System of Food Control in Russia

    Ermakova, Irina V.

    Food safety is quite important for human health in all countries. Humanity has the uniform space and must take care about all parts of it. Pollution of one region leads to the same state of others regions through water, land, air, living organisms. The poor-quality or poisoned food products can pollute the territory and influence negatively on the environment. The food security is important, especially, in connection with the possibility of terrorist attacks. The Federal Service of control in sphere of protection of the rights of consumers was formed in Russia in 2004. This Service carries out the activity directly and through the territorial organizations in interaction with administrative structures in food control and inspection, namely in sanitary-epidemiological service, veterinary service, grain service, inspection of trade connections and standardization and certification. The control is carried out on the basis of laws. The law № 29-FZ concerns the quality and safety of foodstuff and how to control it. The law 134-FZ attracted the protection of the rights of legal persons and individual businessmen. The modification of the law №234-FZ about protection of the rights of consumers is connected with new food - GMOs. Great attention is paid to the safety of new food. Private companies also perform analysis of heavy metals, mycotoxins, radiation and the presence of bacteria, virus or genetically modified organisms. We would like to thank the group Pilot Study "Food chain security" for very important work concerning food safety in different countries. They help us to understand internal problems in Russia and to create the cooperation with other countries. All these steps are very important for the protection population from toxic food.

    1997-01-01

    When NASA started plarning for manned space travel in 1959, the myriad challenges of sustaining life in space included a seemingly mundane but vitally important problem: How and what do you feed an astronaut? There were two main concerns: preventing food crumbs from contaminating the spacecraft's atmosphere or floating into sensitive instruments, and ensuring complete freedom from potentially catastrophic disease-producing bacteria, viruses, and toxins. To solve these concerns, NASA enlisted the help of the Pillsbury Company. Pillsbury quickly solved the first problem by coating bite-size foods to prevent crumbling. They developed the hazard analysis and critical control point (HACCP) concept to ensure against bacterial contamination. Hazard analysis is a systematic study of product, its ingredients, processing conditions, handling, storage, packing, distribution, and directions for consumer use to identify sensitive areas that might prove hazardous. Hazard analysis provides a basis for blueprinting the Critical Control Points (CCPs) to be monitored. CCPs are points in the chain from raw materials to the finished product where loss of control could result in unacceptable food safety risks. In early 1970, Pillsbury plants were following HACCP in production of food for Earthbound consumers. Pillsbury's subsequent training courses for Food and Drug Administration (FDA) personnel led to the incorporation of HACCP in the FDA's Low Acid Canned Foods Regulations, set down in the mid-1970s to ensure the safety of all canned food products in the U.S.

    At the time of the Second Republic of Poland, Warsaw, the capital of the rebirth country, was a neglected town as regards sanitary conditions. The genesis of this situation dates back to the period of the national bondage by the Russian partitioner, and since 1915 by the German invader who did not care about the problems associated with public health. The sanitary and hygienic conditions worsened significantly in 1916, after incorporating into Warsaw large out-of-town regions whose housing was of the rural character with numerous wooden cottages, field roads, without any sanitary sewage system. Poor municipal sanitary-maintenance conditions and infectious diseases spreading in Warsaw made the Town Authorities implement preventive action and entrust sanitary surveillances with this difficult task. These surveillances were set up at the time of the First World War, and after 1920 were changed into sanitary offices. Their duties included control of acute infectious diseases, sanitary inspection of living quarters, sites of production and selling of food articles, plants, service outlets, shops of a different character, as well as surveillance of food purchased by the inhabitants. In each sanitary office a doctor was employed who supervised the work of one, two or three sanitary inspectors.

    This study analyses law bills towards the sanitary control of alcohol advertisement in the mass media presented to the Brazilian Congress from 1988 to 2004. The sanitary control of this advertising is a controversial issue bringing about an ethical-political debate in which the health-protecting interests conflict with commercial ones even after scientific evidence has established increasing alcohol intake as a health and social issue worldwide. The content analysis of 67 of such law bills was carried out, and these proposals were shown to consist mostly of strategies to both cope with alcohol advertising by dissociating from the product those values that might interfere with the children and teenagers' building of their social identity and limit advertisement contents in the mass media given the higher vulnerability of the subjects in that age range. This study reveals complexes challenges for the control of alcohol advertisement that in turn lead to rethinking the action of the State apparatus in dealing with this major public health issue.

    Poor menstrual knowledge and access to sanitary products have been proposed as barriers to menstrual health and school attendance. In response, interventions targeting these needs have seen increasing implementation in public and private sectors. However, there has been limited assessment of their effectiveness. Assess the impact of providing reusable sanitary pads and puberty education on girls' school attendance and psychosocial wellbeing outcomes. A cluster quasi-randomised controlled trial was conducted across 8 schools, including 1124 girls, in rural Uganda. Schools were allocated to one of four conditions: the provision of puberty education alone; reusable sanitary pads alone; puberty education and reusable sanitary pads; and a control (no intervention). The primary outcome was school attendance. Secondary outcomes reflected psychosocial wellbeing. At follow-up, school attendance had worsened for girls across all conditions. Per-protocol analysis revealed that this decline was significantly greater for those in the control condition d = 0.52 (95%CI 0.26-0.77), with those in control schools having a 17.1% (95%CI: 8.7-25.5) greater drop in attendance than those in any intervention school. There were no differences between the intervention conditions. High rates of school drop-out and transfer meant the trial suffered from substantial participant drop-out. Intention-to-treat analyses using two different imputation strategies were consistent with the main results, with mean differences of 5.2% attendance in best-case and 24.5% in worst-case imputations. Results were robust to adjustments for clustering. There was no impact of the interventions on girls' self-reported shame or insecurity during menstruation. Results of the trial support the hypothesised positive impact of providing sanitary pads or puberty education for girls' school attendance in a developing country context. Findings must be interpreted with caution in light of poor participant retention

    This research was aimed at assessing the fertilizer quality and public health implications of using digestate biofertilizer from the anaerobic digestion of food wastes and human excreta. Twelve (12) kg of food wastes and 3kg of human excreta were mixed with water in a 1:1 w/v to make 30-l slurry that was fed into the anaerobic digester to ferment for 60days at mesophilic temperature (22-31°C). Though BOD, COD, organic carbon and ash content in the feedstock were reduced after anaerobic digestion by 50.0%, 10.6%, 74.3% and 1.5% respectively, nitrogen, pH and total solids however increased by 12.1%, 42.5% and 12.4% respectively. The C/N ratios of the feedstock and compost are 135:1 and 15.8:1. The residual total coliforms of 2.10×10(8)CFU/100ml in the digestate was above tolerable limits for direct application on farmlands. Microbial analysis of the digestate biofertilizer revealed the presence of Pseudomonas, Klebsiella, Clostridium, Bacillus, Bacteroides, Penicillum, Salmollena, and Aspergillus. Klebsiella, Bacillus, Pseudomonas, Penicillum and Aspergillus can boost the efficiency of the biofertilizer through nitrogen fixation and nutrient solubility in soils but Klebsiella again and Salmollena are potential health risks to end users. Further treatment of the digestate for more efficient destruction of pathogens is advised. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The use of self-help manuals or bibliotherapy could be an effective resource to treat obesity, but their effects on the elaborative processes of food cravings remain unclear. The present study examined whether bibliotherapy can effectively reduce food cravings in an overweight and obese adult population. 80 participants were randomly allocated either to the Self-help Manual group or the Intention-control group. They had to apply each resource over a period of 3 months whenever they felt a craving arise. During the baseline period most of the participants reported grazing as the main cause of their weight gain. Compared to baseline, the results of the third month of the follow-up revealed that intentions had paradoxical effects on food thought suppression, preoccupation with food, negative affect and guilty feelings; but the Self-help Manual promoted positive changes on the food cravings trait and its dimensions, food thoughts suppression, emotional and behavioural reactions to intrusions and BMI. These findings suggest that the Self-help Manual could be useful in reducing food cravings.

    At the time of the Second Republic of Poland, in March 1922, the city of Vilnius together with the Vilnius Region was incorporated into Poland. Sanitary and health negligence was one of the main problems of the city. The genesis of that situation dates back to the 120-year national bondage, when the city was under the Russian rule. Since 1915 it was occupied by the German invader, and from January to April 1919 it belonged to Soviet Russia. The legacy left by this epoch concerned bad housing conditions, problems with removal of impurities, scarcity of fresh water supply, uneven and dirt roads, which along with other bionegative factors resulted in dissemination of contagious diseases and occurrence of other health risks. In Vilnius of the interwar period, similarly to other big cities in Poland, sanitary surveillances played a significant role in controlling acute contagious diseases, inspecting sanitary conditions of living quarters, service outlets, industrial plants, sites of production and selling food articles, as well as surveillance of food. Municipal doctors supervised the work of sanitary inspectors in each sanitary office.

    This paper provides an overview of the responsibilities and jurisdictional boundaries of Health Canada (HC) and Agriculture and Agri-Food Canada (AAFC) with regard to food regulation in Canada. It examines their interagency coordination within the federal structure and with other levels of government, industry, and the consumer. The international developments are considered with the North American Free Trade Agreement (NAFTA) and the Canada, United States Trade Agreement (CUSTA) being regarded as likely to have a significant future impact. The federal food safety and quality system is complex and fragmented. Federal food regulation comes under the jurisdiction of four federal departments: HC, AAFC, Industry Canada (IC), and Fisheries and Oceans Canada (FOC). All four departments are involved with inspection, surveillance, and the analysis of food sold in Canada. In addition, Canada's ten provincial and two territorial governments have provincial-, regional-, municipal-, and local-level governments that also have jurisdiction over food safety and quality. Consideration is first given to the main legislative provision covering food--the Federal Food and Drugs Act. This Act is administered by several of the Federal Government departments. The role of these departments is examined individually along with additional, more specific legal provisions for which responsibility is not divided (in particular, the Canada Agricultural Products [CAP] Act administered by AAFC, and the Consumer Packaging and Labeling Act [CPLA] administered by IC). The various reviews that have taken place in the recent past and those still in progress are considered, and the final part of this paper looks at the international developments that are likely to have a major impact on the future development of the Canadian food control system.

    Obesity is a major public health problem and substantially increases the risk of type 2 diabetes, hypertension, stroke, cardiovascular, respiratory problems, gall bladder disease, osteoarthritis and sleep apnoea, as well as certain cancers. The prevalence of obesity is rapidly increasing worldwide. However, for individuals weight is regulated within a narrow range. This regulation depends on energy intake (in the form of food) and energy expenditure. Recently, there has been a remarkable increase in our understanding of the homeostatic mechanisms that control food intake and energy homeostasis. There is increased understanding of the central regulation of appetite. In particular, this includes new knowledge about the hypothalamus and brainstem and their relation to food intake regulation. Peripheral hormones (notably adipostat factors and gut hormones) have now been found to be important in food intake regulation. Complex central circuitry controls food intake. Circulating hormones, in particular the gut hormones have unexpectedly been found to be very important in appetite control. The gut hormones are thus new and exciting targets for future obesity therapies.

    Food control systems are being established or revamped in many countries because of problems occurring along the food chain and the obligations of governments towards the World Trade Organization. The main components of an ideal food control system are food legislation, administration, enforcement and supporting bodies like analytical services and consumer organizations. Mauritius introduced modern legal instruments in 1998 in an attempt to reinvigorate food control. This article describes the components of the Mauritian Food Control System (MFCS). An appraisal of these components is then made. The methodology comprised a literature review and in-depth interviews with key informants and stakeholders of the local food control system. Although much progress was made with the introduction of new food legislation in 1998, other components of the local system like enforcement and various supporting bodies did not receive appropriate support. Other countries could use the lessons drawn from the Mauritian experience while setting up or upgrading their food control systems.

    Most countries have expended much effort to develop food safety control systems to ensure safe food supplies within their borders. China, as one of the world's largest food producers and consumers,pays a lot of attention to food safety issues. In recent years, China has taken actions and implemented a series of plans in respect to food safety. Food safety control systems including regulatory, supervisory,and science and technology systems, have begun to be established in China. Using, as a base, an analysis of the current Chinese food safety control system as measured against international standards, this paper discusses the need for China to standardize its food safety control system. We then suggest some policies and measures to improve the Chinese food safety control system.

    Full Text Available La tuberculosis (TB sigue siendo una patología prevalente a nivel mundial. Chile tiene un Programa de Control de la Tuberculosis eficaz desde el año 1973, el que ha permitido disminuir la incidencia anual de la enfermedad en 50% cada década, hasta alcanzar el año 2000 una tasa de 20 x 100.000 habitantes ("umbral de la etapa de eliminación ". Sin embargo, desde entonces el país ha presentado un descenso menor, llegando a una situación estacionaria, con tasas cercanas a 13 x 100.000 los años 2009-2011. Este deterioro en la situación epidemiológica de la tuberculosis en Chile corre paralelo a las sucesivas reducciones del presupuesto asignado a su control. La mayor incidencia de tuberculosis en pacientes VIH, población migrante, población privada de libertad y adultos mayores han demostrado no ser los responsables de este retroceso epidemiológico. La mayor causa de este deterioro se debe a la pérdida de la capacidad diagnóstica de los casos transmisores de la enfermedad en la comunidad (casos pulmonares bacilíferos, reflejado por el bajo índice de pesquisa (número de baciloscopias realizadas por cada 1.000 consultas de morbilidad general de adultos en la atención primaria, que es 12,8 x 1.000 a nivel nacional, en circunstancias que la meta es 50 x 1,000. Esto ha determinado la reducción de 193.416 baciloscopias de pesquisa entre los años 2006-2010, lo que sin duda mantiene en circulación un número estimado de 966pacientes contagiosos no diagnosticados en este período de 4 años. Esto hace temer que en Chile se pudiera producir próximamente un nuevo aumento de la tuberculosis, es decir, una reversión epidemiológica, como la que se observó en Brasil, Cuba y Uruguay cuando se redujeron los recursos destinados a sus programas antituberculosos. El control de este rebrote, en esos países, requirió de la inyección de ingentes recursos económicos. Este deterioro epidemiológico es más intenso en la Región Metropolitana

    Objectives Conduct a feasibility study on the effect of menstrual hygiene on schoolgirls' school and health (reproductive/sexual) outcomes. Design 3-arm single-site open cluster randomised controlled pilot study. Setting 30 primary schools in rural western Kenya, within a Health and Demographic Surveillance System. Participants Primary schoolgirls 14–16 years, experienced 3 menses, no precluding disability, and resident in the study area. Interventions 1 insertable menstrual cup, or monthly sanitary pads, against ‘usual practice’ control. All participants received puberty education preintervention, and hand wash soap during intervention. Schools received hand wash soap. Primary and secondary outcome measures Primary: school attrition (drop-out, absence); secondary: sexually transmitted infection (STI) (Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoea), reproductive tract infection (RTI) (bacterial vaginosis, Candida albicans); safety: toxic shock syndrome, vaginal Staphylococcus aureus. Results Of 751 girls enrolled 644 were followed-up for a median of 10.9 months. Cups or pads did not reduce school dropout risk (control=8.0%, cups=11.2%, pads=10.2%). Self-reported absence was rarely reported and not assessable. Prevalence of STIs in the end-of-study survey among controls was 7.7% versus 4.2% in the cups arm (adjusted prevalence ratio (aPR) 0.48, 0.24 to 0.96, p=0.039), 4.5% with pads (aPR=0.62; 0.37 to 1.03, p=0.063), and 4.3% with cups and pads pooled (aPR=0.54, 0.34 to 0.87, p=0.012). RTI prevalence was 21.5%, 28.5% and 26.9% among cup, pad and control arms, 71% of which were bacterial vaginosis, with a prevalence of 14.6%, 19.8% and 20.5%, per arm, respectively. Bacterial vaginosis was less prevalent in the cups (12.9%) compared with pads (20.3%, aPR=0.65, 0.44 to 0.97, p=0.034) and control (19.2%, aPR=0.67, 0.43 to 1.04, p=0.075) arm girls enrolled for 9 months or longer.

    Terahertz radiation or T-rays, show promise in quality control of food products. As T-rays are inherently sensitive to water, they are very suitable for moisture detection. This proves to be a valuable asset in detecting the moisture content of dried food, a critical area for some products. As T-rays are transparent to plastics, food additives can also be probed through the packaging, providing checks against a manufacturer's claims, such as the presence of certain substances in foods.

    Food safety became a relevant subject due to the increasing search for a better way of life and consciousness of the consumers to stand on one's rights to acquire healthy products. The use of substances in animals destined for human consumption requires from pharmacokinetics to residue depletion studies, with the establishment of limitative values so that do not constitute a risk to health. Beyond the substances used deliberately, others coming from environment contamination or contamination of feeding stuffs consumed by these animals may reach human through the diet. The aims of this paper are to collect and discuss the main federal acts covering chemical residues and contaminants in food of animal origin in Brazil, besides those on measures to control veterinary medicinal products and additives for use in animal nutrition. The chronological presentation of the legal basis intends to facilitate the interpretation of the acts inside respective political and economics scenarios. The actions proposed from the different agents involved into the regulatory systems are discussed from the public health point of view.

    Full Text Available Muscoloskeletal disorders are the first cause of disability and the second cause of permanent disablement in Italy. Osteoarthritis is the most frequent rheumatic disease and affects about 4 million Italians. In spite of that, data concerning social costs are lacking. On account of this lack we measured sanitary costs of 314 patients suffering from osteoarthritis. A retrospective, prevalence- based multicentric study was performed using a bottom-up approach. The study period was 12 months and referred to 1999. Eight percent of patients didn’t take any drug for the treatment of osteoarthritis; NSAIDs were prescribed to 86.9% of patients, analgesics to 29.9%, chondroprotective drugs to 7.6%, and gastroprotective drugs to 36.9%. Total sanitary costs came to 455 € / patient / year: 122 € were spent on diagnostics, 293 € on therapy and 40 € on management of drug-related gastropathy. Since the costs of anti-inflammatory drugs came to 30 € we calculated iatrogenic cost factor of 2.3. Moreover, the study supplied interesting informations about prescriptive habits, which differ in Italy from international guidelines for the medical treatment of OA, about patient management, because of hospitalization, which by itself absorbs 1/3 of resources, and about physiotherapy, which costs twice as much as pharmacological therapy. At last, data analysis gave the cue for suggestions on changing patients’ management.

    Full Text Available This paper gives an overview of the food packaging process in seven food companies in the dairy and confectionery sector. A total of 23 production runs have been analyzed regarding the three packers' rules outlined in the Serbian legislation and process capability tests related to statistical process control. None of the companies had any type of statistical process control in place. Results confirmed that more companies show overweight packaging compared to underfilling. Production runs are more accurate than precise, although in some cases the productions are both inaccurate and imprecise. Education / training of the new generation of food industry workers (both on operational and managerial level with courses in the food area covering elements of quality assurance and statistical process control can help in implementing effective food packaging.

  10. How food controls aggression in Drosophila.

    Directory of Open Access Journals (Sweden)

    Rod S Lim

    Full Text Available How animals use sensory information to weigh the risks vs. benefits of behavioral decisions remains poorly understood. Inter-male aggression is triggered when animals perceive both the presence of an appetitive resource, such as food or females, and of competing conspecific males. How such signals are detected and integrated to control the decision to fight is not clear. For instance, it is unclear whether food increases aggression directly, or as a secondary consequence of increased social interactions caused by attraction to food. Here we use the vinegar fly, Drosophila melanogaster, to investigate the manner by which food influences aggression. We show that food promotes aggression in flies, and that it does so independently of any effect on frequency of contact between males, increase in locomotor activity or general enhancement of social interactions. Importantly, the level of aggression depends on the absolute amount of food, rather than on its surface area or concentration. When food resources exceed a certain level, aggression is diminished, suggestive of reduced competition. Finally, we show that detection of sugar via Gr5a+ gustatory receptor neurons (GRNs is necessary for food-promoted aggression. These data demonstrate that food exerts a specific effect to promote aggression in male flies, and that this effect is mediated, at least in part, by sweet-sensing GRNs.

    2014-10-01

    Switzerland is a confederation consisting of 26 states, the so-called 'cantons'. In the field of food control, the Swiss federal state is in charge of issuing the regulations (Food law and associated texts), whereas enforcement is assigned to the cantons. The offices in charge of food control are the cantonal laboratories headed by a 'Cantonal chemist'. These offices pursue three main goals: to protect consumer health, to protect the consumer against frauds and to ensure food handling under good hygiene conditions. To that purpose, the Cantonal chemist heads both a laboratory and a staff of inspectors, who are responsible for the control of food products (including meat and drinking water), the control of hygiene and production at factories, stores, restaurants, etc. as well as the control of common goods and household items such as toys, clothing, make-up, dishes, cookware, jewelry and so on. All laboratories and inspection bodies are accredited according to ISO norms EN 17'020 and EN 17'025. The offices headed by the cantonal chemists analyze annually about 110'000 samples on sale or from factories, whereas the inspection bodies perform roughly 45'000 inspections (without primary producers and occasional importers).

    The maintenance of the body weight at a stable level is a major determinant in keeping the higher animals and mammals survive. Th e body weight depends on the balance between the energy intake and energy expenditure. Increased food intake over the energy expenditure of prolonged time period results in an obesity. Th e obesity has become an important worldwide health problem, even at low levels. The obesity has an evil effect on the health and is associated with a shorter life expectancy. A complex of central and peripheral physiological signals is involved in the control of the food intake. Centrally, the food intake is controlled by the hypothalamus, the brainstem, and endocannabinoids and peripherally by the satiety and adiposity signals. Comprehension of the signals that control food intake and energy balance may open a new therapeutic approaches directed against the obesity and its associated complications, as is the insulin resistance and others. In conclusion, the present review summarizes the current knowledge about the complex system of the peripheral and central regulatory mechanisms of food intake and their potential therapeutic implications in the treatment of obesity.

    Full Text Available Sea urchin (Paracentrotus lividus is an edible echinoderm very common in the Mediterranean sea. In the Sardinian gastronomic tradition it represents a product very used in some periods of the year, but in practice the sanitary controls by the competent authorities are very difficult. The Reg. (EC n. 853/2004 provides that, as regards as the control on production, echinoderms are assimilable to live bivalve molluscs, with the exception of the provisions on purification. In this work a proposal for the sanitary management of the phases of gathering, transport and selling of the sea urchins has been studied.

    Many species of invasive plants are spreading out rapidly in Europe. The common milkweed occupies increasingly more area. Being poisonous, most animals will not graze on it however rabbits would be an effective organism for the biological control of milkweed. Rabbit kittens can learn the maternal diet in various ways. They prefer aromatic foods which their mother had eaten during pregnancy or lactation period, -even if it is poisonous- but they can also learn the maternal diet from the fecal pellets deposited by the mother into the nest during the nursing events. The present study was aimed to investigate if rabbit kittens can learn that the common milkweed is a potential food also. In the first 10days of their lives kits got fecal pellets originating from individuals having fed on common milkweed previously. When weaned on day 28 postpartum, these pups preferred the milkweed in the 3-way food choice test, opposite to the control group. Most surprisingly in a second experiment it was also shown that the common milkweed was also preferred by the kittens if their mother ate it not during, but one month before pregnancy.

    Many animals hoard food, including humans, but despite its pervasiveness, little is known about the physiological mechanisms underlying this appetitive behavior. We summarize studies of food hoarding in humans and rodents with an emphasis on mechanistic laboratory studies of species where this behavior importantly impacts their energy balance (hamsters), but include laboratory rat studies although their wild counterparts do not hoard food. The photoperiod and cold can affect food hoarding, but food availability is the most significant environmental factor affecting food hoarding. Food-deprived/restricted hamsters and humans exhibit large increases in food hoarding compared with their fed counterparts, both doing so without overeating. Some of the peripheral and central peptides involved in food intake also affect food hoarding, although many have not been tested. Ad libitum-fed hamsters given systemic injections of ghrelin, the peripheral orexigenic hormone that increases with fasting, mimics food deprivation-induced increases in food hoarding. Neuropeptide Y or agouti-related protein, brain peptides stimulated by ghrelin, given centrally to ad libitum-fed hamsters, duplicates the early and prolonged postfood deprivation increases in food hoarding, whereas central melanocortin receptor agonism tends to inhibit food deprivation and ghrelin stimulation of hoarding. Central or peripheral leptin injection or peripheral cholecystokinin-33, known satiety peptides, inhibit food hoarding. Food hoarding markedly increases with pregnancy and lactation. Because fasted and/or obese humans hoard more food in general, and more high-density/high-fat foods specifically, than nonfasted and/or nonobese humans, understanding the mechanisms underlying food hoarding could provide another target for behavioral/pharmacological approaches to curb obesity.

  2. [Epidemiologic aspects of a new approach to monitoring hygienic food handling using the hazard analysis critical control points (HACCP) system].

    Matyás, Z

    1992-10-01

    The hitherto used traditional control of food hygiene focused on assessment whether the controlled sanitary and technological practice is consistent with requirements of regulations sometimes comprises also details of minor importance. To put it briefly, in the course of the production process are many check-up points, but only some or possibly only one is a critical control point. Moreover, by periodic supervision the hygienist is able to record the hygienic and technological state typical only for the time of control. Microbiological examination of final products can reveal only negative sequelae of microbial processes; it does not provide information on the conditions of contamination nor ensure protection against it. For these and other reasons the conclusion is reached that the hitherto used traditional approach of the hygiene supervision is not quite effective and must be replaced by a more active approach focused on the control of factors threatening the wholesomeness already during the production process. The new approach to supervision of food hygiene is the HACCP system (hazard analysis critical control points). The system works rationally as it is based on analysis of systematically assembled data on the causes and conditions which evoked the illness of the consumers by food products or meals. HACCP can be described as prompt, as health or quality problems are revealed immediately after their genesis during production or processing and are eliminated immediately. The system is also comprehensive as it comprises not only the basic technological process incl. processing or modification of ingredients but takes into account also the handling of the given food product after termination of production and in particular final culinar processing. The system can be applied to all pathogenic agents transmitted by foods to man from bacteria and their toxins, viruses, parasites, moulds and mycotoxins, biotoxins but also contaminants and radionuclides.

    Full Text Available In the article the short historical review on the design of sanitary rooms and their configurations is given. The main errors of the recent years, which led to the decrease in accommodation convenience because of the wrong approach from both the architect and engineers, are given. It is possible to use a small useful area for sanitary facilities, but it is connected with the lack of possibility of connecting washing and dishwashers. The author considers the options of engineering equipment placement in sanitary rooms taking into account the convenience of use, safety, and also resource-saving aspect. Various solutions on the organization of heating and ventilation are provided. The possible technical solutions allowing solving a flooding problem of the first floors in elite housing estates in case of accident are offered with the help of full waterproofing of sanitary rooms, and also the whole area of the apartment. The main attention was focused on the improvements of sanitary rooms for one-room and two-room apartments, which are the most demanded in the modern market of real estate. Layout solutions of the reduced bathrooms on the placement of the necessary equipment with choice justification are provided. The attention is paid to the layout solution for modern kitchens on order to increase their comfort by the use of special two-section sinks, and also a grinder of food waste in order to allow to lower the load of the systems of rubbish disposal of a building, by dumping the crushed garbage in an internal sewer network. Various options of evolutionary development of sanitary rooms for increasing the comfort degree are given. First of all, the development should happen in the direction of not only sanitation and hygiene, but also of the maintenance of the physical health of the people living in the building. It can be carried out by increase in a useful area of sanitary rooms, installation of exercise machines, medical bathtubs and a Jacuzzi

    In December 2009, during a piscicide treatment targeting the invasive Asian carp in the Chicago Sanitary and Ship Canal, Rhodamine WT dye was released to track and document the transport and dispersion of the piscicide. In this study, two modeling approaches are presented to reproduce the advection and dispersion of the dye tracer (and piscicide), a one-dimensional analytical solution and a three-dimensional numerical model. The two approaches were compared with field measurements of concentration and their applicability is discussed. Acoustic Doppler current profiler measurements were used to estimate the longitudinal dispersion coefficients at ten cross sections, which were taken as reference for calibrating the longitudinal dispersion coefficient in the one-dimensional analytical solution. While the analytical solution is fast, relatively simple, and can fairly accurately predict the core of the observed concentration time series at points downstream, it does not capture the tail of the breakthrough curves. These tails are well reproduced by the three-dimensional model, because it accounts for the effects of dead zones and a power plant which withdraws nearly 80 % of the water from the canal for cooling purposes before returning it back to the canal.

    Despite awareness of the importance of food allergy as a public health issue, recalls and adverse reactions linked to undeclared allergens in foods continue to occur with high frequency. To reduce the overall incidence of such problems and to ensure that food-allergic consumers have the information they need to prevent adverse reactions, it is important to understand which allergen control practices are currently used by the food industry. Therefore, the U.S. Food and Drug Administration carried out directed inspections of registered food facilities in 2010 to obtain a broader understanding of industry allergen control practices in the United States. The results of these inspections show that allergen awareness and the use of allergen controls have increased greatly in the last decade, but that small facilities lag in implementing allergen controls.

    This work examines the main features of modern electronic noses (e-noses) and their most important applications in food control in this new century. The three components of an electronic nose (sample handling system, detection system, and data processing system) are described. Special attention is devoted to the promising mass spectrometry based e-noses, due to their advantages over the more classical gas sensors. Applications described include process monitoring, shelf-life investigation, freshness evaluation, authenticity assessment, as well as other general aspects of the utilization of electronic noses in food control. Finally, some interesting remarks concerning the strengths and weaknesses of electronic noses in food control are also mentioned.

    Full Text Available In order to fulfill the legal requirements for the transition to the new risk-based model of the state control (supervision in the Federal Service for Consumer Rights Protection and Human Welfare, the methodical approaches to the classification of economic entities and activities of potential risk of injury have been developed. The risk assessment takes into account the frequency of violations of sanitary legislation, the severity of the consequences of these violations for the health and extent of negative effects, which is estimated in terms of population under the influence of the economic entity. Algorithms and methods for calculating the exposed population: workers, consumers, including consumer food products, non-food products and services; residents of settlements under the negative impact of air pollution, water and soil, have been developed. Regional and federal registries of objects for sanitary and epidemiological supervision are formed. Testing of the risk-based approaches in the regions allowed excluding the low risk harm objects when forming the audit plans for 2016, due to what the number of planned inspections all over country was reduces by more than 20 %. The basic directions of further improvement of the risk-based model of sanitary and epidemiological surveillance: its extension to the system of technical regulation and consumer protection; scientific substantiation of its volume, content and laboratory support of the scheduled inspections of objects belonging to different classes of health risk; improving procedures and methods for evaluating the effectiveness and efficiency of risk-based supervisory activities; creation of an effective system of risk communication between the sanitary and epidemiological surveillance, economic entities, public organizations and associations and civil society.

    It is essential to guarantee the safety of unprocessed plants and food supplements if consumers' health is to be protected. Although botanicals and their preparations are regulated at EU level, at least in part, there is still considerable discretion at national level, and Member States may choose to classify a product either as a food supplement or as a drug. Accurate data concerning the finished products and the plant used as the starting point are of major importance if risks and safety are to be properly assessed, but in addition standardized criteria for herbal preparation must be laid down and respected by researchers and manufacturers. Physiologically active as well as potentially toxic constituents need to be identified, and suitable analytical methods for their measurement specified, particularly in view of the increasing incidence of economically motivated adulteration of herbal raw materials and extracts. It remains the duty of food operators to keep up with the scientific literature and to provide sufficient information to enable the adaptation of specifications, sampling schemes and analytical methods to a fast-changing environment.

    Full Text Available

    Most well-known enzymatic methods have been employed in the bioanalysis of food, required by law in a number of countries. Food is a complex sample and hence difficult to analyze. In food analysis, there are many different types of sample, such as: clear or turbid, colorless or colored, neutral or acid, liquids, pastes and solids, that can be analyzed by enzymatic methods. The oxidase - peroxidase system may be used for specific analyses. In the reaction catalyzed by the oxidase, hydrogen is transferred from the substrate to oxygen and hydrogen peroxide is formed as an intermediate. Hydrogen peroxide then reacts with a leuco dye in the presence of the enzyme peroxidase and a color develops which is measured in the visible spectrum. This article is a review of two enzymes, peroxidase (POD and glycerol-3-phosphate oxidase (GPO, pointing out their principal sources, characteristics and applications.

    Surveillance and control of food-borne human pathogens, such as Listeria monocytogenes, is a critical aspect of modern food safety programs at food production facilities. This study evaluated contamination patterns of Listeria species at a poultry food production facility, and evaluated the efficacy of procedures to control the contamination and transfer of the bacteria throughout the plant. The presence of Listeria species was studied along the production chain, including raw ingredients, food-contact, non-food-contact surfaces, and finished product. All isolates were sub-typed by pulsed-field gel electrophoresis (PFGE) to identify possible entry points for Listeria species into the production chain, as well as identifying possible transfer routes through the facility. The efficacy of selected in-house sanitizers against a sub-set of the isolates was evaluated. Of the 77 different PFGE-types identified, 10 were found among two or more of the five categories/areas (ingredients, food preparation, cooking and packing, bulk packing, and product), indicating potential transfer routes at the facility. One of the six sanitizers used was identified as unsuitable for control of Listeria species. Combining PFGE data, together with information on isolate location and timeframe, facilitated identification of a persistent Listeria species contamination that had colonized the facility, along with others that were transient.

    As existing technologies are refined and novel microbial inactivation technologies are developed, there is a growing need for a metric that can be used to judge equivalent levels of hazard control stringency to ensure food safety of commercially sterile foods. A food safety objective (FSO) is an output-oriented metric that designates the maximum level of a hazard (e.g., the pathogenic microorganism or toxin) tolerated in a food at the end of the food supply chain at the moment of consumption without specifying by which measures the hazard level is controlled. Using a risk-based approach, when the total outcome of controlling initial levels (H(0)), reducing levels (ΣR), and preventing an increase in levels (ΣI) is less than or equal to the target FSO, the product is considered safe. A cross-disciplinary international consortium of specialists from industry, academia, and government was organized with the objective of developing a document to illustrate the FSO approach for controlling Clostridium botulinum toxin in commercially sterile foods. This article outlines the general principles of an FSO risk management framework for controlling C. botulinum growth and toxin production in commercially sterile foods. Topics include historical approaches to establishing commercial sterility; a perspective on the establishment of an appropriate target FSO; a discussion of control of initial levels, reduction of levels, and prevention of an increase in levels of the hazard; and deterministic and stochastic examples that illustrate the impact that various control measure combinations have on the safety of well-established commercially sterile products and the ways in which variability all levels of control can heavily influence estimates in the FSO risk management framework. This risk-based framework should encourage development of innovative technologies that result in microbial safety levels equivalent to those achieved with traditional processing methods.

    This chapter discusses the importance of modelling and control in increasing food process efficiency and ensuring product quality. Various approaches to both modelling and control in food processing are set in the context of the specific challenges in this industrial sector and latest developments in each area are discussed. Three industrial case studies are used to demonstrate the benefits of advanced measurement, modelling and control in food processes. The first case study illustrates the use of knowledge elicitation from expert operators in the process for the manufacture of potato chips (French fries) and the consequent improvements in process control to increase the consistency of the resulting product. The second case study highlights the economic benefits of tighter control of an important process parameter, moisture content, in potato crisp (chips) manufacture. The final case study describes the use of NIR spectroscopy in ensuring effective mixing of dry multicomponent mixtures and pastes. Practical implementation tips and infrastructure requirements are also discussed.

    2006-04-03

    Food regulation in the main is aimed at protecting the consumer's health, increasing economic viability, harmonizing well-being and engendering fair trade on foods within and between nations. Consumers nowadays are faced with food or food ingredients that may derive from distant countries or continents, and with a less transparent food supply. Safety concerns must cover the range of different food chains relevant to a certain food product or product group, including all relevant producers, manufacturing sites and food service establishments within a country as well as those importing into the country. Hazard analysis at critical control points (HACCP), good manufacturing practice (GMP) and good hygiene practice (GHP) are major components of the safety management systems in the food supply chain. Principally, "a hazard" is a biological, chemical or physical agent in, or condition of, food that has the potential to cause an adverse health effect. The likelihood of occurrence and severity of the same is important for the assessment of the risk presented by the hazard to the food supply chain. The Government's regulatory mechanisms in accordance with the WTO agreements (HACCPs, sanitary and phytosanitary measures, etc.) oversee the analyses of public health problems and their association to the food supply. Under the WTO SPS Agreements and the codes of practices issued by the Codex Alimentarius Commission, there now exists a benchmark for international harmonization that guarantee the trade of safe food. Inevitably, food safety is still mainly the responsibility of the consumer.

    The sensory experience of eating is an important determinant of food intake control, often attributed to the positive hedonic response associated with certain sensory cues. However, palatability is just one aspect of the sensory experience. Sensory cues based on a food's sight, smell, taste and texture are operational before, during and after an eating event. The focus of this review is to look beyond palatability and highlight recent advances in our understanding of how certain sensory characteristics can be used to promote better energy intake control. We consider the role of visual and odour cues in identifying food in the near environment, guiding food choice and memory for eating, and highlight the ways in which tastes and textures influence meal size and the development of satiety after consumption. Considering sensory characteristics as a functional feature of the foods and beverages we consume provides the opportunity for research to identify how sensory enhancements might be combined with energy reduction in otherwise palatable foods to optimize short-term energy intake regulation in the current food environment. Moving forward, the challenge for sensory nutritional science will be to assess the longer-term impact of these principles on weight management.

    Full Text Available L. monocytogenes has been established in different plants for the production of food, including dairy plants, abattoirs, plants for the processing of fish, as well as those for the production of ready-to-eat (RTE food and this fact is being considered as the primary mechanism of food contamination with this bacteria. There is also the factor of numerous and diverse contaminated production equipment, because it has certain parts that are inaccessible for the necessary cleaning and disinfection. The temperature, position, as well as the material of the work surface are also linked to the contamination of plants with this bacteria. Investigations carried out so far have helped toward the better understanding of the manner and time of contamination of food items in the course of the production process, but there are still unresolved problems, including most certainly the biggest one - the adherence of bacteria and the creation of a biofilm, when the bacteria is in that condition more resistant to so-called stress factors which are usually used in the food industry for the purpose of decontamination of the surfaces with which foods come into contact. The control of L. monocytogenes in food production plants is possible primarily by using an integrated programme, compatible with the systems Hazard Analysis Critical Control Point (HACCP and Good Hygiene Practice (GHP, necessary in the production of food that is safe for the consumer. Essentially, the control measures that can contribute to reducing the incidence of findings of L.monocytogenes in the finished product, as well as the reducing of the level of contamination with this bacteria are linked, on the one hand, with hygiene procedures in the production process, and, on the other, with the applied technological procedures.

  2. Physiology of food poisoning microorganisms and the major problems in food poisoning control.

    Science.gov (United States)

    Gould, G W; Abee, T; Granum, P E; Jones, M V

    1995-12-01

    There remains considerable public concern regarding the current high level of food poisoning disease in Europe and the fact that, year by year, it continues to rise rather than fall. At the same time, there are strong and increasing demands from consumers for foods that are more convenient, fresher, more natural, less heavily processed (e.g. 'REPFEDS' and 'Sous Vide' foods, mildly heated and distributed at chill temperatures; Lund and Notermans, 1992), less heavily preserved (e.g. less acid, less salt, less sugar; Gould, 1995) and less reliant on additive preservatives than hitherto (e.g. sulphite, nitrite, organic acids and esters; Russell and Gould, 1991). Most of these trends result in a general reduction in the intrinsic preservation of foods. Furthermore, many food poisoning microorganisms escape the attention of preservation techniques altogether, reaching the consumer more or less directly from contaminated foods, most often foods of animal origin. It has therefore been argued that a substantial reduction in food poisoning in the near future will be difficult to achieve unless we obtain a greatly improved understanding of the physiology of the most important target organisms (Knochel and Gould, 1995). This knowledge must then be exploited in ways which effectively improve our means for the control of these hazards and reduce the risk to the consumer. A three year AAIR Concerted Action Programme (PL920630: 'Physiology of Food Poisoning Microorganisms') was therefore initiated in 1992 in order to bring together research groups working on the physiology and related aspects of food poisoning microorganisms. The principal objectives of the programme were: 1. To determine the physiological, biochemical and genetical bases of the organisms' survival of and responses to food-relevant stresses; 2. to determine the physiological and genetical factors influencing infectivity and toxinogenesis; 3. to understand the physiological bases of those synergistic systems that

    Full Text Available This paper is devoted to the questions of further development of agricultural and food policy in the Russian Federation. The subject of in-depth consideration is the problem related to ensuring food safety. A critical review and analysis of major regulations in the field of food safety is made, including in the implementation of sanitary and epidemiological surveillance. The necessity of the expansion of measures to improve the statistics of food poisoning is grounded. The basic reasons for the spread of management practices of production and sale of food products that pose a threat to human life are revealed. The factors of unhindered penetration of local markets in the cities and the surrounding countrysides with counterfeiting, smuggling and production of global junk food manufacturers and consumer goods are defined. A systematic view is put on the problems of food production in the private farms, ways to limit direct access to the market of food and food raw materials, which production was not controlled and who have not passed state registration, are suggested. One of these problems is creation of independent industrial structures that link production and sales of small-scale sector goods.

    There are conflicting results on the growth and health of weanling pigs (Sus scrofa) fed high-fiber diets, and responses may differ according to sanitary conditions. This study was conducted to explore the growth, health, and fecal microbiota of weanling pigs fed either low- or high-fiber diets in 2 different sanitary conditions. Forty-eight pigs weaned at 28 d of age were individually housed in "good" (clean) or "poor" (unclean) sanitary conditions. During 2 consecutive phases, pigs were fed 2 diets containing a low (control) or high level of fiber: 121 or 169 g/kg total dietary fiber (TDF) for Phase I and 146 or 217 g/kg for Phase II, which lasted 15 and 20 d, respectively. This led to 4 experimental treatments in Phase I in a 2 × 2 factorial arrangement (2 sanitary conditions × 2 diets) and 8 experimental treatments in Phase II in a 2 × 2 × 2 factorial arrangement (2 sanitary conditions × 2 diets in Phase I × 2 diets in Phase II). The poor sanitary conditions led to a reduced G:F (0.617 vs. 0.680 for poor and good sanitary conditions, respectively; P = 0.01) over the entire experimental period. The number of pigs with diarrhea in Phase I tended to be greater in the poor sanitary conditions with the high-fiber diet than the control diet (7 vs. 3 pigs, P = 0.07). Enterococcus was prominent in feces of these diarrheic pigs. At 5 wk after weaning, compared with good sanitary conditions, the fecal microbiota of pigs housed in poor sanitary conditions was characterized by more Lactobacillus (9.24 vs. 8.34 log cfu/g, P pigs in poor sanitary conditions contained more total VFA and proportionally more butyrate (9.7 vs. 5.7% for poor and good conditions, respectively, independently of dietary treatment, P pigs fed the high-fiber diet during Phase II contained less Enterococcus bacteria than pigs fed the control diet (4.06 vs. 4.56 log cfu/g; P = 0.05), and more total VFA with a decreased proportion of branched-chain fatty acids (5.0 vs. 6.1%; P = 0.006).

    Although the prefrontal cortex influences motivated behavior, its role in food intake remains unclear. Here, we demonstrate a role for D1-type dopamine receptor-expressing neurons in the medial prefrontal cortex (mPFC) in the regulation of feeding. Food intake increases activity in D1 neurons of the mPFC in mice, and optogenetic photostimulation of D1 neurons increases feeding. Conversely, inhibition of D1 neurons decreases intake. Stimulation-based mapping of prefrontal D1 neuron projections implicates the medial basolateral amygdala (mBLA) as a downstream target of these afferents. mBLA neurons activated by prefrontal D1 stimulation are CaMKII positive and closely juxtaposed to prefrontal D1 axon terminals. Finally, photostimulating these axons in the mBLA is sufficient to increase feeding, recapitulating the effects of mPFC D1 stimulation. These data describe a new circuit for top-down control of food intake.

    It is too early to draw a definitive account of the sanitary impacts of the Fukushima accident but the author tries to assess them by comparing with Chernobyl accident. It appears that the sanitary consequences will be far less dramatic because of lower radiation doses and efficient counter-measures taken quickly after the accident such as evacuation of contaminated areas and restriction about the consumption of food produced locally.

    Hamrin, Pia; Hoeft, Birgit

    2012-01-01

    The manufacture of infant food is a highly complex process and needs an effective quality control beyond classical in-process parameters and a final microbiological analysis. To ensure a safe end -product, various tools, such as the Hazard Analysis Critical Control Points (HACCP), have been developed to facilitate the management of food safety. Every single infant formula ingredient must have an excellent quality and safety approach because even if an ingredient is used in very small quantities in a single product, serious consequences may arise if the quality and product safety are not taken seriously by the ingredient manufacturer. The purpose of this article was twofold: firstly, to briefly describe existing Quality Management Systems and, secondly, to highlight the consequences of non-quality.

    The quick development concerning the commercial application of food irradiation in the USA recently resulted in growing marketing of irradiated red meat as well as irradiated fresh and dried fruits. These gamma and electron irradiation technologies require specific dosimetry systems for process control. The new version of the Sunna dosimeter has been characterized in gamma, electron and bremsstrahlung radiation fields by measuring the optically stimulated luminescence (osl) at 530 nm both below and above 1 kGy, i.e. for disinfestation and for meat irradiation purposes. No humidity and no significant dose rate effect on the green osl signal was observed. The temperature coefficient was determined from 0°C up to about 40°C and to stabilize the osl signal after irradiation a heat treatment method was introduced. Based on these investigations the Sunna 'gamma' film is a suitable candidate for dose control below and above 1 kGy for food irradiation technologies.

    Eight wells of the LFW series monitor groundwater quality in the Steed Pond Aquifer (Water Table) beneath the Interim Sanitary Landfill at the Savannah River Site. These wells are sampled semiannually to comply with the South Carolina Department of Health and Environmental Control Modified Municipal Solid Waste Permit 025500-1120 and as part of the SRS Groundwater Monitoring Program. Trichlorofluoromethane and 1,1,1-trichloroethane were elevated in one sidegradient well and one downgradient well during 1996. Zinc was elevated in three downgradient wells and also was detected in the associated laboratory blanks for two of those wells. Specific conductance was elevated in one background well and one sidegradient well. Barium and copper exceeded standards in one sidegradient well, and dichloromethane (a common laboratory contaminant) was elevated in another sidegradient well. Barium, copper, and dichloromethane were detected in the associated blanks for these wells, also. The groundwater flow direction in the Steed Pond Acquifer (Water Table) beneath the Interim Sanitary Landfill was to the southeast (universal transverse Mercator coordinates). The flow rate in this unit was approximately 210 ft/year during first quarter 1996 and 180 ft/yr during third quarter 1996.

    In the irradiation process, absorbed dose is the key parameter that must be controlled. In general, the minimum absorbed dose needed to accomplish a desired effect, such as insect disinfestation or pathogen reduction, is already known from previous research, and is often prescribed by government regulations. The irradiation process is effective, however, only if the food can tolerate this dose without experiencing unwanted changes in flavor or appearance. The dose that food can tolerate often depends on such things as the variety of the fruit or vegetable, where it was grown, the season in which it was harvested and the length of time between harvesting and irradiation. Once the minimum and maximum doses are established, the irradiator operator must make sure that these dose limits are not exceeded. First, a dose mapping using many dosimeters must be undertaken to determine the locations of the minimum and maximum dose in the overall process load. From then on, the process load must always be the same, and, as a key step in the overall process control, dosimeters need to be placed from time to time only at the minimum or maximum locations. The dosimeters must be calibrated and directly trackable to national or international standards, and a fool-proof method of labelling and segregating irradiated from unirradiated product must be used. Radiation sensitive indicators that may help identify irradiated from unirradiated food should not be relied upon, and are not a substitute fro proper dosimetry. (Author)

Inserido em um debate de natureza ético-política, o controle sanitário dessa propaganda é uma questão controversa, pois os interesses pela proteção da saúde se confrontam com os interesses comerciais mesmo ante as evidências científicas de que o consumo crescente de álcool é um problema social e de saúde no mundo contemporâneo. Realizou-se a análise de conteúdo de 67 documentos, na qual se mostra que as propostas formuladas, majoritariamente, apresentam-se como estratégias de enfrentamento a essa propaganda, procurando desvincular valores associados ao produto que interferem na construção da identidade social de crianças e adolescentes e limitar o conteúdo das mensagens veiculadas nos meios de comunicação de massa, dado que este segmento está mais vulnerável. O estudo evidencia complexos desafios para o controle da propaganda, que implicam repensar a própria atuação do Estado ante esse relevante problema de Saúde Pública.This study analyses law bills towards the sanitary control of alcohol advertisement in the mass media presented to the Brazilian Congress from 1988 to 2004. The sanitary control of this advertising is a controversial issue bringing about an ethical-political debate in which the health-protecting interests conflict with commercial ones even after scientific evidence has established increasing alcohol intake as a health and social issue worldwide. The content analysis of 67 of such law bills was carried out, and these proposals were shown to consist mostly of strategies to both cope with alcohol advertising by dissociating from the product those values that might interfere with the children and teenagers' building of their social identity and limit advertisement contents in the mass media given the

  15. Real and perceived risks for mycotoxin contamination in foods and feeds: challenges for food safety control.

    Science.gov (United States)

    2010-04-01

    Mycotoxins are toxic compounds, produced by the secondary metabolism of toxigenic moulds in the Aspergillus, Alternaria, Claviceps, Fusarium, Penicillium and Stachybotrys genera occurring in food and feed commodities both pre- and post-harvest. Adverse human health effects from the consumption of mycotoxins have occurred for many centuries. When ingested, mycotoxins may cause a mycotoxicosis which can result in an acute or chronic disease episode. Chronic conditions have a much greater impact, numerically, on human health in general, and induce diverse and powerful toxic effects in test systems: some are carcinogenic, mutagenic, teratogenic, estrogenic, hemorrhagic, immunotoxic, nephrotoxic, hepatotoxic, dermotoxic and neurotoxic. Although mycotoxin contamination of agricultural products still occurs in the developed world, the application of modern agricultural practices and the presence of a legislatively regulated food processing and marketing system have greatly reduced mycotoxin exposure in these populations. However, in developing countries, where climatic and crop storage conditions are frequently conducive to fungal growth and mycotoxin production, much of the population relies on subsistence farming or on unregulated local markets. Therefore both producers and governmental control authorities are directing their efforts toward the implementation of a correct and reliable evaluation of the real status of contamination of a lot of food commodity and, consequently, of the impact of mycotoxins on human and animal health.

    Objetivos: las guías alimentarias para conseguir una alimentación correcta establecen como aconsejable tomar tres o más raciones de cereales integrales de grano completo al día. Sin embargo, la norma es poco conocida en nuestro entorno, afectando el incumplimiento a la práctica totalidad de la población. Por ello, el objetivo de la presente revisión es analizar los beneficios nutricionales y sanitarios asociados al consumo de cereales de grano completo y las posibles ventajas que podrían derivarse del cumplimiento con consumo aconsejado para estos alimentos. Métodos: búsqueda bibliográfica en relación con el tema. Resultados: los cereales de grano completo aportan cantidades elevadas de hidratos de carbono, fibra, vitaminas y minerales, cuya contribución a la dieta media ayuda a alcanzar las ingestas recomendadas y los objetivos nutricionales vigentes, por lo que su consumo en la cantidad aconsejada supone un beneficio nutricional. Por otra parte, diversos estudios señalan que un aumento en el consumo de cereales de grano completo se asocia con una protección frente al padecimiento de diversas enfermedades crónico-degenerativas (cardiovasculares, diabetes, síndrome metabólico y cáncer), ayudando en el mantenimiento de la salud digestiva y del peso corporal. Estos resultados pueden ser debidos al aporte de nutrientes, fibra y fitoquímicos, procedente de estos alimentos, así como al desplazamiento de la dieta de otros productos con un perfil nutricional menos conveniente, teniendo en cuenta la composición de la dieta media española. De hecho, el consumo de cereales de grano completo ha sido relacionado con una posible mejora en la microbiota intestinal y una mayor protección antioxidante. Pese a estas ventajas, el consumo de cereales es mirado con recelo por diversos individuos, especialmente por aquellas personas preocupadas por el control de peso, y los beneficios adicionales asociados al consumo de cereales de grano completo no son

    2016-12-01

    Self-control in one's food choices often depends on the regulation of attention toward healthy choices and away from temptations. We tested whether selective attention to food cues can be modulated by a newly developed proactive self-control mechanism-control readiness-whereby control activated in one domain can facilitate control in another domain. In two studies, we elicited the activation of control using a color-naming Stroop task and tested its effect on attention to food cues in a subsequent, unrelated task. We found that control readiness modulates both overt attention, which involves shifts in eye gaze (Study 1), and covert attention, which involves shift in mental attention without shifting in eye gaze (Study 2). We further demonstrated that individuals for whom tempting food cues signal a self-control problem (operationalized by relatively higher BMI) were especially likely to benefit from control readiness. We discuss the theoretical contributions of the control readiness model and the implications of our findings for enhancing proactive self-control to overcome temptation in food choices.

  19. Millefeuille The emergence of a multi-layered controls system in the European food sector

    Directory of Open Access Journals (Sweden)

    Bernd M.J. van der Meulen

    2006-06-01

    Full Text Available More and more substances used in (the processing of food as well as food products travel world wide and as a result the food production chain is becoming increasingly complex. It goes without saying that within a free European market, the safety of food products that reach the consumer at the end of the production chain depends entirely on the safety and control measures that are taken in all stages of the production process. Food crises have brought to light serious shortcomings in safety assurance and have made regulatory reform an important issue at European level over the past ten years. In order to re-establish public confidence in food supply, food science, food law and food controls, the European Commission initiated a major regulatory reform. This article goes into the restructuring of European food legislation as far as this affects food controls. The restructuring of European food law has resulted in a controls system in which recourse is had to a command and control system. The food sector is squeezed between four layers of controls. Although a heavily regulated system might seem logical in response to food safety crises the question arises whether this will ultimately prove to be the most effective way to safeguard food safety.

    The present work addresses the need for new devices felt in the context of quality control, especially in the food industry. Due to the spectral dependence of the attenuation coefficient, a novel dual-parameter sensor for colour and refractive index was developed and tested. The sensor employs plastic optical fibres to measure the transmitted optical power in three measurement cells each with a different incident wavelength. The performance of the sensor was tested using several dyes at different concentrations and aqueous solutions of glycerine and ethanol. Results show that this technique allows the monitoring of refractive index and colour without cross-sensitivity.

    Full Text Available Palytoxin (PLTX, one the most potent marine toxins, and/or its analogs, have been identified in different marine organisms, such as Palythoa soft corals, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria. Although the main concern for human health is PLTXs entrance in the human food chain, there is growing evidence of adverse effects associated with inhalational, cutaneous, and/or ocular exposure to aquarium soft corals contaminated by PLTXs or aquaria waters. Indeed, the number of case reports describing human poisonings after handling these cnidarians is continuously increasing. In general, the signs and symptoms involve mainly the respiratory (rhinorrhea and coughing, skeletomuscular (myalgia, weakness, spasms, cardiovascular (electrocardiogram alterations, gastrointestinal (nausea, and nervous (paresthesia, ataxia, tremors systems or apparates. The widespread phenomenon, the entity of the signs and symptoms of poisoning and the lack of control in the trade of corals as aquaria decorative elements led to consider these poisonings an emerging sanitary problem. This review summarizes literature data on human poisonings due to, or ascribed to, PLTX-containing soft corals, focusing on the different PLTX congeners identified in these organisms and their toxic potential.

In general, the inhibitory effect of phage and phage cocktail was better at 4 °C than that at 25 °C, whereas the opposite result was observed in Chinese cabbage, and phage cocktail was better than either single phage. A significant reduction in bacterial numbers (1.5–4 log CFU/sample, p < 0.05 was observed in all tested foods. The two phages on the three food samples were relatively stable, especially at 4 ºC, with the phages exhibiting the greatest stability in milk. Our research shows that our phages have potential effectiveness as a bio-control agent of Salmonella in foods.

    Food chain, food safety, and food-processing sectors face new challenges due to globalization of food chain and changes in the modern consumer preferences. In addition, gradually increasing microbial resistance, changes in climate, and human errors in food handling remain a pending barrier for the efficient global food safety management. Consequently, a need for development, validation, and implementation of rapid, sensitive, and accurate methods for assessment of food safety often termed as foodomics methods is required. Even though, the growing role of these high-throughput foodomic methods based on genomic, transcriptomic, proteomic, and metabolomic techniques has yet to be completely acknowledged by the regulatory agencies and bodies. The sensitivity and accuracy of these methods are superior to previously used standard analytical procedures and new methods are suitable to address a number of novel requirements posed by the food production sector and global food market. © 2017 Elsevier Inc.

    Loss of lateral prefrontal cortex (lPFC)-mediated attentional control may explain the automatic tendency to eat in the face of food. Here, we investigate the neurocognitive mechanism underlying attentional bias to food words and its association with obesity using a food Stroop task. We tested 76 healthy human subjects with a wide body mass index (BMI) range (19-35kg/m(2)) using fMRI. As a measure of obesity we calculated individual obesity scores based on BMI, waist circumference and waist-to-hip ratio using principal component analyses. To investigate the automatic tendency to overeat directly, the same subjects performed a separate behavioral outcome devaluation task measuring the degree of goal-directed versus automatic food choices. We observed that increased obesity scores were associated with diminished lPFC responses during food attentional bias. This was accompanied by decreased goal-directed control of food choices following outcome devaluation. Together these findings suggest that deficient control of both food-directed attention and choice may contribute to obesity, particularly given our obesogenic environment with food cues everywhere, and the choice to ignore or indulge despite satiety.

    The present study aimed to extend the application of the reflective-impulsive model to restrained eating and explore the effect of automatic attention (impulsive system) on food choices. Furthermore, we examined the moderating effects of general inhibitory control (G-IC) and food-specific inhibitory control (F-IC) on successful and unsuccessful restrained eaters (US-REs). Automatic attention was measured using "the EyeLink 1000," which tracked eye movements during the process of making food choices, and G-IC and F-IC were measured using the Stop-Signal Task. The results showed that food choices were related to automatic attention and that G-IC and F-IC moderated the predictive relationship between automatic attention and food choices. Furthermore, among successful restrained eaters (S-REs), automatic attention to high caloric foods did not predict food choices, regardless of whether G-IC or F-IC was high or low. Whereas food choice was positively correlated with automatic attention among US-REs with poor F-IC, this pattern was not observed in those with poor G-IC. In conclusion, the S-REs had more effective self-management skills and their food choices were affected less by automatic attention and inhibitory control. Unsuccessful restrained eating was associated with poor F-IC (not G-IC) and greater automatic attention to high caloric foods. Thus, clinical interventions should focus on enhancing F-IC, not G-IC, and on reducing automatic attention to high caloric foods.

    2015-01-01

    The Sanitary and Phytosanitary( SPS) measures are technical regulations,standards,and requirements closely related to food safety,plant and animal health,and environmental safety,aiming to prevent disease,pests,pathogens and other alien risk from entering China.Pork is favorite meat for Chinese consumers; its safety directly concerns the safety of whole food supply chain with rapid increasing of pork import. This paper analyzed SPS management system of swine and pork import,and evaluated SPS efficiency of swine industry in China from SPS notification number,swine health situation,and pork import standard. The study found that as for SPS notification number and chemical residue control standard,China’s SPS protection level is relatively high,while the control level of swine diseases is still low. In China,SPS management system has the problem of involving multiple authorities and poor coordination among them,leading to some standards lacking scientific basis and low enforcement.

    Full Text Available This study aims to design metal food packaging with hazard analysis critical control point (HACCP. First, theory of HACCP was introduced in detail. Taking empty cans provided by Wuxi Huapeng Food Packaging Company as an example, we studied migration of bisphenol compounds in coating of food can to food stimulant. Moreover, packaging design of luncheon meat can was taken as an example to confirm whether HACCP system could effectively control migration of phenolic substance. Results demonstrated that, coating of such empty were more likely to contain multiple bisphenol compounds such as bisphenol A (BPA, and bisphenol A diglycidyl ether (BADGE was considered as the leading bisphenol pollutant; food stimulant of different types, storage temperature and time could all impact migration of bisphenol compounds. HACCP system was proved to be effective in controlling hazards of phenolic substance in luncheon meat can and could reduce various phenolic substance indexes to an acceptable range. Therefore, HACCP can control migration of phenolic substance and recontamination of food and thus ensure food safety.

  15. Regulatory control of genetically modified (GM) foods: likely developments.

    Schilter, Benoît; Constable, Anne

    2002-02-28

    The placing of genetically modified (GM) crops on the European market requires a regulatory approval supported by a thorough safety evaluation. This approach has been applied to all GM crops presently on the market. Despite this stringent process there has been an increasing public concern about the impact of GM foods on human health and the environment. In this context, regulatory control may develop in several directions. One response to the public concern is to strengthen the data requirements for the risk assessment process. Several avenues have been proposed. They include the application of technologies such as proteomics and metabolomics to assess unintended changes, and the development of predictive methods to evaluate allergenicity. Obligations for post-launch surveillance have appeared in regulations. Criteria are required to define when and why such approaches are necessary. Significant challenges including feasibility and validation of the methods, and safety relevance of the data generated will have to be addressed before any general application of these new approaches. Effective monitoring requires the ability to identify the presence of GM products and trace their origin. Traceability and labeling are therefore important developments in the GM food regulatory arena. Both require the development of reliable analytical detection tools.

  17. Traditional Chinese Medicine, Food Therapy, and Hypertension Control: A Narrative Review of Chinese Literature.

    Science.gov (United States)

    Zou, Ping

    2016-01-01

    Despite the lack of English literature about Traditional Chinese Medicine (TCM) food therapy, there is abundant Chinese literature about the application of food therapy for hypertension control. This paper summarizes basic concepts of TCM, the principles of food therapy and its application for hypertension control according to Chinese literature. In TCM, food is conceptualized according to both nutritional and functional aspects, and can be used to treat illnesses. Four principles of TCM food therapy including light eating, balancing the "hot" and "cold" nature of food, the harmony of the five flavors of food, and consistency between dietary intake and different health conditions, can be used to facilitate hypertension control. Based on a statistical analysis of antihypertensive foods recommended in 20 books on the application of food therapy for hypertension control, the 38 most frequently recommended are celery, tomato, banana, hawthorn, garlic, onion, seaweed, apple, corn, green beans, persimmon, laver, kiwi, watermelon, eggplant, carrots, mushroom, peanut, soy products, sea cucumber, buckwheat, garland chrysanthemum, spinach, honey, dairy products, vinegar, black fungus, jellyfish, green onion, shepherd's purse, soybean, potato, pear, winter melon, bitter melon, oat, pea, and tea. Food therapy emphasizes the therapeutic effects of food, considering its nature, taste, and function on human balanced health, which leads to optimal blood pressure control. Current literature suggests that food therapy is effective in blood pressure control and can be incorporated into blood pressure self-management in the Chinese population.

    Irradiation Food has been approved in 52 countries worldwide. In Korea, 26 food items have been approved since 1987. Recently, the irradiation technology with high dose was applied for the development of Korean space foods. Besides the sanitary purpose, the irradiation technology was used for elimination of undesired products such as food allergens, nitrite, biogenic amines, and so on. In this paper, the status of irradiation in the field of food and other biotechnology in Korea will be presented. Food irradiation is known to be the best method for controlling pathogenic microorganisms and one of the best alternatives to the chemical fumigants or preservatives usually used for a sanitation treatment for international trade. Also, there are larger industrial groups dedicated to radiation processing other than food irradiation industry. In this paper, the status of irradiation food science and biotechnology in Korea will be presented.

  20. Control of food intake by fatty acid oxidation and ketogenesis.

    Science.gov (United States)

    Scharrer, E

    1999-09-01

    Fatty acid oxidation seems to provide an important stimulus for metabolic control of food intake, because various inhibitors of fatty acid oxidation (mercaptoacetate, methyl palmoxirate, R-3-amino-4-trimethylaminobutyric acid) stimulated feeding in rats and/or mice, in particular when fed a fat-enriched diet, and long-term intravascular infusion of lipids reduced voluntary food intake in various species, including humans. The feeding response to decreased fatty acid oxidation was due to a shortening of the intermeal interval with meal size remaining unaffected. Thus, energy derived from fatty acid oxidation seems to contribute to control of the duration of postmeal satiety and meal onset. Since inhibition of glucose metabolism by 2-deoxy-D-glucose affects feeding pattern similarly, and spontaneous meals were shown to be preceded by a transient decline in blood glucose in rats and humans, a decrease in energy availability from glucose and fatty acid oxidation seems to be instrumental in eliciting eating. Since the feeding response of rats to inhibition of fatty acid oxidation was abolished by total abdominal vagotomy and pretreatment with capsaicin destroying non-myelinated afferents and attenuated by hepatic branch vagotomy, fatty acid oxidation in abdominal tissues, especially in the liver, apparently is signalled to the brain by vagal afferents to affect eating. Brain lesions and Fos immunohistochemistry were employed to identify pathways within the brain mediating eating in response to decreased fatty acid oxidation. According to these studies, the nucleus tractus solitarii (NTS) of the medulla oblongata represents the gate for central processing of vagally mediated afferent information related to fatty acid oxidation. The lateral parabrachial nucleus of the pons seems to be a major relay for pertinent ascending input from the NTS. In particular the central nucleus of the amygdala, a projection area of the parabrachial nucleus, appears to be crucial for eating

    Foodborne illness continues as a considerable threat to public health. Despite improved hygiene management systems and increased regulation, pathogenic bacteria still contaminate food, causing sporadic cases of illness and disease outbreaks worldwide. For many centuries, microbial antagonism has been used in food processing to improve food safety. An understanding of the mode of action of this microbial antagonism has been gained in recent years and potential applications in food and feed safety are now being explored. This review focuses on the potential opportunities presented, and the limitations, of using microbial antagonism as a biocontrol mechanism to reduce contamination along the food chain; including animal feed as its first link. © 2014 Society of Chemical Industry.

  13. Electrochemical treatment of leachates from sanitary landfills

    Directory of Open Access Journals (Sweden)

    ANNABEL FERNANDES

    2013-06-01

    Full Text Available The electrochemical treatment of leachate samples from a Portuguese intermunicipal sanitary landfill was carried out using anodic oxidation. The treatment was performed in a pilot plant that possesses an electrochemical cell, with boron-doped diamond electrodes, working in batch mode with recirculation. The influence of the applied current density and the flow rate on the performance of the electrochemical oxidation was investigated. Current density was decreased by steps, during the degradation, in order to study this effect on the efficiency of the process. For the assays run at equal flow rate and initial current intensity, chemical oxygen demand (COD removal seems to depend mainly on the charge passed and the variation of the current density during the anodic oxidation process can reduce the energetic costs. An increase in the recirculation flow rate leads to an increase in the organic load removal rate and a consequent decrease in the energetic costs, but it decreases the nitrogen removal rate. Also, the bias between dissolved organic carbon and COD removals increases with flow rate, indicating that an increase in recirculation flow rate decreases the mineralization index.

Gyps vultures, which usually base their diet almost exclusively on carcasses of medium and large-sized mammals, whereas all other scavengers rely on broader ranges of prey. The availability of food for scavengers in Western Europe has not been limited during recent decades permitting the existence and growth of huge vulture populations. From 2000 onwards, however, EU sanitary legislation has progre...

    Nowadays exists the possibility of marketing products possibly polluted with radioactive isotopes, by that some countries like Mexico, they have been given to the task of creating legal bases and the necessary infrastructure with the end of carrying out the radiological surveillance of nutritious import products. In this work the legal bases that our country has established for the radiological control are presented besides the results of this radiological control carried out through the gamma spectroscopy analysis of nutritious import products sent to our country through diverse companies that import foods produced mainly in European countries.

    A maximum of forty-eight wells of the LFW series monitor groundwater quality in the Steed Pond Aquifer (Water Table) beneath the Sanitary Landfill at the Savannah River Site (SRS). These wells are sampled quarterly to comply with the South Carolina Department of Health and Environmental Control Domestic Water Permit DWP-087A and as part of the SRS Groundwater Monitoring Program. Chloroethene (vinyl chloride) and trichloroethylene were the most widespread constituents exceeding standards during 1997. Lead (total recoverable), 1,4-dichlorobenzene, mercury, benzene, dichloromethane (methylene chloride), a common laboratory contaminant, tetrachloroethylene, 1,2-dichloroethane, gross alpha, tritium, and 1.2-dichloropropane also exceeded standards in one or more wells. The groundwater flow direction in the Steed Pond Aquifer (Water Table) beneath the Sanitary Landfill was to the southeast (universal transverse Mercator coordinates). The flow rate in this unit was approximately 139 ft/year during first quarter 1997 and 132 ft/year during fourth quarter.

    The paper deals with a number of aspects of current interest and significance on the subject of the microbiological testing of food with particular reference to the role of research institutes. The main objectives of microbiological testing of food are essentially two: (i) to establish the absence of a human health hazard due to microbial contamination of food (food safety); and (ii) to define the quality standard of food (food quality). As far as the first of these objectives is concerned, the outcome of the assay necessarily emerges not only from identification of pathogens but also from definition of their pathogenicity and virulence characteristics and of critical factors for their transmission. Alongside the classic pathogens, evidence has recently been found indicating that four additional bacteria, namely Yersinia enterocolitica, Campylobacter jejuni, Vibrio cholerae non 0-1 and Listeria monocytogenes, also play an important role in food-borne disease. The most characteristic biological, ecological and epidemiologic aspects related to human food-borne disease are described for these bacteria. As regards the second objective, i.e. food quality, stress is laid on the role played by microbial indicators and their predictivity for pathogenic micro-organisms, which does not always exist. This depends on three basic differential factors: (i) biological characteristics giving rise to different diffusion, dilution and extinction phenomena, or, on the other hand, multiplication of such pathogens in the environment and in food; (ii) resistance to the natural inactivation mechanisms, whether of a general or specific nature, of each alimentary substrate; and (iii) the ecological and epidemiological pattern. By way of examples, two experiences indicating the lack of predictivity of the faecal indicators for enterovirus and Vibrio cholerae non 0-1 are reported. Nevertheless, standard microbiological testing for mesophilic flora and indicators are fundamental instruments

    The international experience gained during the past two centuries indicates that the most efficient and rational way to ensure the protection of the territories occupied by the therapeutic and health-promotion facilities, spa centres, and health resorts together with their natural medical resources is to set up sanitary (mountainous sanitary) protection districts or zones along the perimeter of these territories. Beginning from 2000, numerous changes and amendments have been annually introduced in the Russian legislation intended to ensure efficacious control over the rational exploitation of the territories of therapeutic and health-promotion value and their natural medical resources. These initiatives have negative effect on the activities of these organizations and the quality of the services they are expected to provide. Taken together these effects lead to the degradation of the spa and health resort business. Bearing in mind the current conditions for economic activities, it is proposed, in contrast to the former global approach, to envisage in the aforementioned projects the establishment of the sanitary (mountainous sanitary) protection districts or zones and determine their borders based on the results of the assessment of their potential for the protection of therapeutic factors and other valuable resources. Equally important is the maximum reduction of the areas of the second and third zones taking into account their relevant objective characteristics. In certain cases, the protective district may coincide with the second zone. As far as the federal health resorts and large territories of special health-promotion value are concerned, some of them may have two or more sanitary (mountainous sanitary) protection districts. Both the owners and the users of these territories should be provided the necessary and sufficient possibilities for the rational nature use at the grounds and in the adjacent water areas suitable for the development of health resort

    This study explored differences in mothers' and fathers' food parenting strategies, specifically coercive control, structure, and autonomy promotion, and whether parenting style and parental responsibility for food parenting related to the use of these strategies. Parents of children aged 2.5-7.5 years ( N = 497) reported about their parenting practices and food parenting strategies. Parenting style accounted for the majority of the variance in food parenting. Fathers were more authoritarian than mothers. Authoritarian and permissive parenting practices were related to more coercive strategies. Mothers reported more food parenting responsibility. Responsibility was related to less coercive practices and more autonomy promotion and structure.

    Continual exposure to food cues in the environment contributes to unhealthy eating behaviour. According to dual-process models, such behaviour is partly determined by automatic processing of unhealthy food cues (e.g., approach bias), which fails to be regulated by controlled processing (e.g., inhibitory control). The current study aimed to investigate the effect of combined avoidance and control training on implicit evaluation (liking), choice, and consumption of unhealthy snack food. Participants were 240 undergraduate women who were randomly allocated to one of four experimental conditions of a 2 (avoidance training: training versus control) x 2 (control training: training versus control) between-subjects design. The combined training group had a more negative implicit evaluation of unhealthy food than either of the two training conditions alone or the control condition. In addition, participants trained to avoid unhealthy food cues subsequently made fewer unhealthy snack food choices. No significant group differences were found for food intake. Participants were women generally of a healthy weight. Overweight or obese individuals may derive greater benefit from combined training. Results lend support to the theoretical predictions of dual-process models, as the combined training reduced implicit liking of unhealthy food. At a practical level, the findings have implications for the effectiveness of interventions targeting unhealthy eating behaviour. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Food safety issues constitute an international topic discussed by many scholars. Although there is an extensive body of literature on comparisons of food safety control practices across different governance structures, these studies have been conducted mainly in terms of qualitative and descriptive analysis. In addition, little attention has been given to family farms. This study addresses the food safety control practices adopted by ifrms with different governance structures in China. Food safety control is expressed by the folowing aspects, i.e., polution-free, green, organic, and/or geographical indication prod-ucts certiifcation, establishment of production records, and pesticide residue testing. Three types of governance structures that engage in agricultural production are distinguished: farmer cooperatives, agricultural companies, and family farms. The food safety control practices of various governance structures are investigated based on a database that comprises 600 vegetable and fruit enterprises in Zhejiang, China. The results show that (1) pesticide residue testing is adopted by the most ifrms, folowed by products certiifcation, and production records are adopted by the fewest ifrms, and (2) agricul-tural companies adopt more food safety control practices than family farms, while farmer cooperatives adopt the fewest food safety control practices. Governance structure features of a cooperative in terms of ownership, decision-making, and income distribution are the main reasons for the low level of food safety control in the cooperative.

    OBJECTIVE: To investigate microbial contamination and critical control points (CCPs) in the preparation and handling of complementary foods in 120 households in Imo state, Nigeria. METHODS: The Hazard Analysis Critical Control Point (HACCP) approach was used to investigate processes and procedures that contributed to microbial contamination, growth and survival, and to identify points where controls could be applied to prevent or eliminate these microbiological hazards or reduce them to acceptable levels. Food samples were collected and tested microbiologically at different stages of preparation and handling. FINDINGS: During cooking, all foods attained temperatures capable of destroying vegetative forms of food-borne pathogens. However, the risk of contamination increased by storage of food at ambient temperature, by using insufficiently high temperatures to reheat the food, and by adding contaminated ingredients such as dried ground crayfish and soybean powder at stages where no further heat treatment was applied. The purchasing of contaminated raw foodstuffs and ingredients, particularly raw akamu, from vendors in open markets is also a CCP. CONCLUSION: Although an unsafe environment poses many hazards for children's food, the hygienic quality of prepared food can be assured if basic food safety principles are observed. When many factors contribute to food contamination, identification of CCPs becomes particularly important and can facilitate appropriate targeting of resources and prevention efforts. PMID:11417038

  7. The Application Of Biofilter System For Reduction Of Methane Emissions From Modern Sanitary Landfills

    Sung, K.; Park, S.

    2007-12-01

    Increased atmospheric concentrations of greenhouse gases (GHG) caused by anthropogenic activities has been related to global climate change. Methane, the second most important GHG after CO2, is 21 times more effective at trapping heat than CO2. Therefore, methane emission control is of utmost importance for global warming reduction. To minimize leachate production and protect groundwater resources, modern sanitary landfills are equipped with composite covers and gas collection systems. Methane from modern sanitary landfills is vented directly to the atmosphere, except for some of the largest landfills where it is recovered as energy and burned at the site. However, the efficiency of energy recovery systems in larger landfills is reduced as the amount of CH4 generated from landfill begins to decrease. In this study, the performance of a lab-scale model biofilter system was investigated to treat CH4 gas emitted from modern sanitary landfills by conducting batch and column experiments using landfill cover soil amended with earthworm cast as the filter bed medium. From the batch experiments to measure the influence of moisture content and temperature of the filter medium on CH4 removal capacity of a biofilter system, the optimum moisture content and temperature were found to be 10-15% by weight and 25-35°C, respectively. The column experiment was conducted to measure the influence of inlet CH4 concentration and CH4 loading rate on CH4 removal capacity of a biofilter system. As the inlet CH4 concentration decreased, the percentage of CH4 oxidized increased. Up to a CH4 loading rate of 2785 g CH4 m3 h- 1 (EBRT = 7.7 min), the CH4 removal efficiency of the biofilter was able to reach 100%. Based on the results of the study, the installation of a properly managed biofilter system should be capable of achieving a reduction in atmospheric CH4 emissions from modern sanitary landfills at low CH4 generation stage.

    The Hazard Analysis and Critical Control Point (HACCP) system is a preventive method of ensuring food safety. Its objectives are the identification of consumer safety hazards that can occur in the production line and the establishment of a control process to guarantee a safer product for the consumer; it is based on the identification of potential hazards to food safety and on measures aimed at preventing these hazards. HACCP is the system of choice in the management of food safety. The principles of HACCP are applicable to all phases of food production, including basic husbandry practices, food preparation and handling, food processing, food service, distribution systems, and consumer handling and use. The HACCP system is involved in every aspect of food safety production (according to the UN Food and Agriculture Organization [FAO] and the International Commission on Microbiological Specifications for Foods [ICMSF]). The most basic concept underlying the HACCP system is that of prevention rather than inspection. The control of processes and conditions comprises the critical control point (CCP) element. HACCP is simply a methodical, flexible, and systematic application of the appropriate science and technology for planning, controlling, and documenting the safe production of foods. The successful application of HACCP requires the full commitment and involvement of management and the workforce, using a multidisciplinary approach that should include, as appropriate, expertise in agronomy, veterinary health, microbiology, public health, food technology, environmental health, chemistry, engineering, and so on according to the particular situation. Application of the HACCP system is compatible with the implementation of total quality management (TQM) systems such as the ISO 9000 series.

    The increased lifespan caused by food limitation has been observed in a wide range of animals including the nematode Caenorhabditis elegans. We show here that the lifespans of eat-2 and eat-5 feeding-defective mutants and a mutant of dbl-1 encoding a TGFβ ligand significantly change between the cultures fed on Escherichia coli strain OP50 or a more nutrient-rich strain HB101. On HB101 food, the eat-2, eat-5 and dbl-1 mutants show increased lifespan compared to that of the wild type. This result is probably due to nutrient limitation because the eat mutations reduce food uptake and the mutation of dbl-1 that regulates expression of several digestive enzymes leads to nutrient limitation. In contrast, the lifespans of the eat-2 and dbl-1 mutants decreased from that of the wild type on OP50 food. We found that live OP50 cells within a worm were markedly more in these mutants than in the wild type, which suggests that impaired digestion of pathogenic OP50 decreased lifespan in the eat-2 and dbl-1 mutants.

    2016-10-25

    In real food, starch is usually forming part of a matrix with lipids and proteins. However, research on this ternary system and interactions between such food components has been scarce so far. The control of food microstructure is crucial to determine the product properties, including sensorial and nutritionals ones. This paper reviews the microstructural principles of interactions between starch, lipids, and proteins in foods as well as their effect on postprandial glycemic response, considering human intrinsic differences on postprandial glycemic responses. Several lines of research support the hypothesis that foods without rapidly digestible starch will not mandatorily generate the lowest postprandial glycemic response, highlighting that the full understanding of food microstructure, which modulates starch digestion, plays a key role on food design from a nutritional viewpoint.

    Food poisoning at care facilities for the elderly has been breaking out approximately ten cases per year nationwide from 2001 to 2010. Especially, it reflected the characteristics of food poisoning caused by noroviruses at a high rate. Usually we have been preventing from food poisoning by noroviruses working on existing measures such as temperature control of food materials, sanitary handlings of cooking tools and table wares, and so on. Additionally, the most effective measures to avoid secondary pollution at care facilities for the elderly is that all members at these facilities have to have a sense of crisis about food poisoning by noroviruses and managers at these facilities must take care of health control for all staff.

    Food choices are often made mindlessly, when individuals are not able or willing to exert self-control. Under low self-control, individuals have difficulties to resist palatable but unhealthy food products. In contrast to previous research aiming to foster healthy choices by promoting high self-control, this study exploits situations of low self-control, by strategically using the tendency under these conditions to rely on heuristics (simple decision rules) as quick guides to action. More specifically, the authors associated healthy food products with the social proof heuristic (i.e., normative cues that convey majority endorsement for those products). One hundred seventy-seven students (119 men), with an average age of 20.47 years (SD = 2.25) participated in the experiment. This study used a 2 (low vs. high self-control) × 2 (social proof vs. no heuristic) × 2 (trade-off vs. control choice) design, with the latter as within-subjects factor. The dependent variable was the number of healthy food choices in a food-choice task. In line with previous studies, people made fewer healthy food choices under low self-control. However, this negative effect of low self-control on food choice was reversed when the healthy option was associated with the social proof heuristic. In that case, people made more healthy choices under conditions of low self-control. Low self-control may be even more beneficial for healthy food choices than high self-control in the presence of a heuristic. Exploiting situations of low self-control is a new and promising method to promote health on impulse. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    2013-08-01

    The Codex Alimentarius (Codex) international food standards help to ensure food safety and promote fair practices in the international food trade. Implementing these standards using a risk management framework (RMF) approach to decision-making is an increasingly common aspect of the food control programmes of national governments. The Codex Alimentarius Commission (CAC) provides guidance at both the system and food commodity levels. In the case of zoonoses, similarities in the risk analysis methodologies used to underpin standard setting by the CAC and the World Organisation for Animal Health (OIE) are highly enabling of integrated food control systems. The CAC and the OIE are increasingly working together to develop their respective standards for foodborne zoonoses and other hazards so that they are non-duplicative, cohesive and utilise the whole food chain. There is a clear need for effective integration of food safety and animal health monitoring and surveillance information to better control foodborne zoonoses. This is increasingly supported by Codex and OIE standards working together in a variety of ways and realisation of benefits is highly dependent on coordination and sharing of information between Competent Authorities and other food safety stakeholders at the national level.

  19. The Maillard reaction and its control during food processing. The potential of emerging technologies.

    Jaeger, H; Janositz, A; Knorr, D

    2010-06-01

    The Maillard reaction between reducing sugars and amino acids is a common reaction in foods which undergo thermal processing. Desired consequences like the formation of flavor and brown color of some cooked foods but also the destruction of essential amino acids and the production of anti-nutritive compounds require the consideration of the Maillard reaction and relevant mechanisms for its control. This paper aims to exemplify the recent advances in food processing with regard to the controllability of heat-induced changes in the food quality. Firstly, improved thermal technologies, such as ohmic heating, which allows direct heating of the product and overcoming the heat transfer limitations of conventional thermal processing are presented in terms of their applicability to reduce the thermal exposure during food preservation. Secondly, non-thermal technologies such as high hydrostatic pressure and pulsed electric fields and their ability to extend the shelf life of food products without the application of heat, thus also preserving the quality attributes of the food, will be discussed. Finally, an innovative method for the removal of Maillard reaction substrates in food raw materials by the application of pulsed electric field cell disintegration and extraction as well as enzymatic conversion is presented in order to demonstrate the potential of the combination of processes to control the occurrence of the Maillard reaction in food processing.

  20. Veterinarians and Public Health: Food Control in the Professionalization of Veterinarians

    Directory of Open Access Journals (Sweden)

    Kari Tove Elvbakken

    2017-06-01

    Full Text Available This article explores the role of food control in the professionalization of veterinarians in Norway. Veterinarians became engaged in public health through food control and market inspection, which were the responsibility of Norway’s city boards of health from the 1860s. Food inspection served a double purpose: to ensure honest trade and to maintain the safety of food. I argue that food control, which was associated with cities’ efforts to secure public health and order, was important to the legitimacy of the veterinarian profession. This activity is not what one today sees as a core practice of veterinarians, which is the prevention and curing of animal sickness. Exploring boundary activities at the fringes of a profession, and especially activity connected to the city and the state, may shed light on the more general sources of professional influence and legitimacy in the Norwegian profession state.

    In this paper are discussed essential issues about the concept, characteristics and general functions of sanitary regulation, as well as the principles and main lines of action contained in the Program of Modernization of the Sanitary Regulation, which is being implemented by the Ministry of Health of Mexico. In addition, some considerations are offered regarding the supporting role of such a program, in the context of the free trade era that Mexico is undergoing. After 40 years of an outdated sanitary regulation based in a non-functional licensing concept, the new and improved scheme relies on several ammendments to the General Health Law. Thus, the present approach, focuses on a set of flexible, simple and efficient rules, strengthened by proven scientific and technical procedures.

  11. Dietary fats, teas, dairy, and nuts: potential functional foods for weight control?

    Science.gov (United States)

    St-Onge, Marie-Pierre

    2005-01-01

    Functional foods are similar to conventional foods in appearance, but they have benefits that extend beyond their basic nutritional properties. For example, functional foods have been studied for the prevention of osteoporosis, cancer, and cardiovascular disease. They have yet to be related to the prevention of obesity, although obesity is one of the major health problems today. The inclusion of foods or the replacement of habitual foods with others that may enhance energy expenditure (EE) or improve satiety may be a practical way to maintain a stable body weight or assist in achieving weight loss; such foods may act as functional foods in body weight control. Some foods that might be classified as functional foods for weight control because of their effects on EE and appetite-including medium-chain triacylglycerols, diacylglycerols, tea, milk, and nuts-are reviewed here. Only human studies reporting EE, appetite, or body weight are discussed. When studies of whole food items are unavailable, studies of nutraceuticals, the capsular equivalents of functional foods, are reviewed. To date, dietary fats seem to be most promising and have been the most extensively studied for their effects on body weight control. However, the weight loss observed is small and should be considered mostly as a measure to prevent weight gain. Carefully conducted clinical studies are needed to firmly ascertain the effect of tea, milk, and nuts on body weight maintenance, to assess their potential to assist in weight-loss efforts, and to ascertain dose-response relations and mechanisms of action for the 4 food types examined.

    Liao, Chunyang; Kannan, Kurunthachalam

    2014-03-15

    Parabens (alkyl esters of p-hydroxybenzoic acid) are widely used as antimicrobial preservatives in personal care products, pharmaceuticals, and foodstuffs. Although parabens have been reported to be used as antimicrobials in certain types of papers (e.g., wet sanitary or hygiene wipes), little is known about the occurrence of these compounds in paper products. In this study, we determined the concentrations of six paraben analogs, methyl (MeP), ethyl (EtP), propyl (PrP), butyl (BuP), benzyl (BzP), and heptyl parabens (HepP), in 253 paper products divided into 18 categories, using liquid chromatography-tandem mass spectrometry (LC-MS/MS). At least one of the six parabens was detected in almost all (detection rate: 98%) paper samples, and the total concentrations (∑PBs; sum of six parabens) ranged from 1.85 to 3,220,000 ng/g (geometric mean (GM): 103; median: 55.1 ng/g). Sanitary wipes contained very high concentrations of ∑PBs (GM: 8300 ng/g). Paper currencies, tickets, business cards, food cartons, flyers, and newspapers contained notable concentrations of ∑PBs, and the GM concentrations in these paper categories were on the order of a few tens to thousands of nanograms per gram. One source of parabens in paper products is the use of these chemicals as antifungal agents. MeP and PrP were the predominant analogs, accounting for approximately 62% and 16% of the total concentrations of parabens, respectively. On the basis of measured concentrations and frequency of handling of paper products, we estimated the daily intake (EDI) of parabens through dermal absorption. The GM and 95th percentile EDI values were 6.31 and 2050 ng/day, respectively, for the general population. Among the paper categories analyzed, sanitary wipes contributed to the majority (>90%) of the exposures.

    The Quality Management System ISO 9001:2008 introduced by the Management Board of the hospital in the year 2007 resulted in change of the methods used by the Hospital Infection Control Team (HICT) to assess the sanitary-and-hygienic condition. The inspection protocol used by HICT was modified as part of the Quality Management System. It was supplemented by the score sheet which made the inspection results more objective. The purpose of the study was to assess the results of the supervision over the sanitary and epidemiologic condition of the hospital as well as personnel training carried out in the years 2007-2010 by the Hospital Infection Control Team (HICT) of Szpital Uniwersytecki nr 2 im. dr. J.Biziela (J.Biziel University Hospital no. 2). 407 inspection protocols issued in the years 2007-2010 were analysed. The sanitary/hygienic condition indicators and personnel education indicators were calculated based on the analysed data. The sanitary/hygienic condition indicator for the entire hospital in the years 2008-2010 amounted to over 91.50% and only in the year 2007 it was 89.33%. While the personnel education indicator for the entire hospital increased from 90.35% in 2007 to 93.75% in 2010. the assessment of hospital units performed on the basis of the new protocol of the sanitary/hygienic condition has been proven in practice, i.e. insufficient personnel education as regards hospital hygiene is efficiently detected by HICT at individual workstations and the Management Board of the hospital is notified on the ongoing basis on the results of supervision provided by HICT.

    Serotonin transporters (SERTs) are pre-synaptic proteins specialized for the clearance of serotonin following vesicular release at central nervous system (CNS) and enteric nervous system synapses. SERTs are high affinity targets in vivo for antidepressants such as serotonin selective reuptake inhibitors (SSRIs). These include 'medical' psychopharmacological agents such as analgesics and antihistamines, a plant extract called St John's Wort (Hypericum). Osteoclasts are the primary cells responsible for bone resorption. They arise by the differentiation of osteoclast precursors of the monocyte/macrophage lineage. The expression of SERTs was increased in RANKL-induced osteoclast-like cells. Using RANKL stimulation of RAW264.7 cells as a model system for osteoclast differentiation, we studied the direct effects of food factor on serotonin uptake. The SSRIs (fluoxetine and fluvoxamine) inhibited markedly (approximately 95%) in serotonin transport in differentiated osteoclast cells. The major components of St. John's Wort, hyperforin and hypericine were significantly decreased in serotonin transport activity. Thus, a new in vitro model using RANKL-induced osteoclast-like cells may be useful to analyze the regulation of SERT by food factors and SSRIs.

    Experiment 1 used 6 preschool boys and Experiment 2 used 6 adult women to explore the effects of food preference on humans' choice in self-control paradigms. The boys showed a higher proportion of responses for more delayed, larger reinforcers (a measure of self-control) when those choices resulted in receipt of the most preferred food compared to when those choices resulted in the least preferred food. Further, the boys chose the less delayed, smaller reinforcers significantly more often when only those choices, as opposed to both choices, resulted in the most preferred food. Conversely, they chose the more delayed, larger reinforcers significantly more often when only those choices, as opposed to both choices, resulted in the most preferred food. Finally, the women demonstrated significantly less sensitivity to reinforcer amount relative to sensitivity to reinforcer delay (another measure of self-control) when they had a higher preference for the juice received as the less delayed, smaller reinforcer than for the juice received as the more delayed, larger reinforcer. Together, the results show that subjects' food preferences can influence self-control for food reinforcers.

  3. Investigation on food sanitation controlling technologies; Shokuhin eisei kanri gijutsu ni kansuru chosa

    Investigation has been made on the current status of food sanitation controlling technologies. Eighty percent of food poisoning is caused by bacte such as Salmonera, enteritis vibrio, staphylococcus, and pathogenic colibacillus. Putrefaction as the cause for food poisoning occurs from proliferation of different microorganisms. Heating sterilization is the main method being performed, but non-heating method may include sterilization by flash and high voltage pulse discharge in addition to ultra-high pressure and ultraviolet ray sterilization. As a result of the questionnaire survey, what is extracted as the problems in the food sanitation controlling technologies is to establish a rinsing and sterilizing method with large sterilization effect, an effective sterilizing method and thawing of processed marine products, and a cooling method in food processing. Increasingly demanded for the future is to develop a foodstuff sanitation control system using as the core the hazard analysis critical control point (HACCP, a quality control program developed by the U.S. NASA to ensure safety in manufacturing space food), and micro-organism control and sterilizing technologies to support the above system. The flash pulse and high-voltage pulse sterilizing technologies as the non-heating sterilizing technology are more effective than the conventional heating sterilization methods also from the aspect of quality retention after sterilization. More active development thereof is desired. (NEDO)

    With the rising prevalence of obesity, hedonic eating has become an important theme in obesity research. Hedonic eating is thought to be that driven by the reward of food consumption and not metabolic need, and this has focused attention on the brain reward system and how its dysregulation may cause overeating and obesity. Here, we begin by examining the brain reward system and the evidence for its dysregulation in human obesity. We then consider the issue of how individuals are able to control their hedonic eating in the present obesogenic environment and compare 2 contrasting perspectives on the control of hedonic eating, specifically, enhanced control of intake via higher cognitive control and loss of control over intake as captured by the food addiction model. We conclude by considering what these perspectives offer in terms of directions for future research and for potential interventions to improve control over food intake at the population and the individual levels.

    The scientific rationale for preventive measures based on sanitary-and-epidemiological surveillance on environmental objects is considered. The sizes of functional zones and space for various types of communal services and amenities and leisure are regulated to ensure good urban vital activities. Multistorey housing causes an increase in the number of negative factors per area units and in their impact on health. A proposal has been made for the standardization of the ranges of urban population upsurge and size, by using the sanitary-and-hygienic rules and norms rather than climatic parameters. A criterion system for assessing the data of statistical observations has been substantiated and 5 levels of analysis and managerial decision-making have been proposed. Cause-and-effect relations may be determined for the parameters of the second level; models of program-oriented studies for the third level, only sanitary-and-epidemiological surveillance is possible for the fourth and fifth levels. The space planning scheme must provide for water supply reserves, generation areas for pure air coming into the town, and waste disposal areas. The general layout may use statistical observation parameters characterizing the second level of occurrence of negative phenomena. The statistical observation parameters characterizing the third and fourth levels of occurrence of negative phenomena may be used for municipal improvements and sanitary maintenance. These characterizing the fourth and fifth level may be used for prevention in therapeutic-and-prophylactic institutions.

  20. Application of hyperspectral imaging in food safety inspection and control: a review.

    Science.gov (United States)

    Feng, Yao-Ze; Sun, Da-Wen

    2012-01-01

    Food safety is a great public concern, and outbreaks of food-borne illnesses can lead to disturbance to the society. Consequently, fast and nondestructive methods are required for sensing the safety situation of produce. As an emerging technology, hyperspectral imaging has been successfully employed in food safety inspection and control. After presenting the fundamentals of hyperspectral imaging, this paper provides a comprehensive review on its application in determination of physical, chemical, and biological contamination on food products. Additionally, other studies, including detecting meat and meat bone in feedstuffs as well as organic residue on food processing equipment, are also reported due to their close relationship with food safety control. With these applications, it can be demonstrated that miscellaneous hyperspectral imaging techniques including near-infrared hyperspectral imaging, fluorescence hyperspectral imaging, and Raman hyperspectral imaging or their combinations are powerful tools for food safety surveillance. Moreover, it is envisaged that hyperspectral imaging can be considered as an alternative technique for conventional methods in realizing inspection automation, leading to the elimination of the occurrence of food safety problems at the utmost.

    2016-08-01

    In phenylketonuria (PKU), little is known about the effect of bitter-tasting phenylalanine-free l-amino acid exposure on taste preference development. The present prospective study aimed to determine the flavour preferences of children with PKU versus healthy control children. Thirty-five children with PKU and 35 age/gender-matched controls, aged 4-13 years, tasted 10 blinded puree foods in random order. They were rated using a seven-point pictorial hedonic scale (super yummy to super yucky) and ranked in preferential order. Caregivers completed a neophobia and food frequency questionnaire on behalf of their children. Both PKU and control groups rated sweet foods higher than savoury, bitter and sour foods. However, control children ranked fruits as a group higher than PKU children (mean 3.7 versus 4.6; P = 0.03), whereas PKU children ranked vegetables as a group higher than controls (mean 5.6 versus 6.3; P = 0.05). Children with PKU had more neophobia and were untrusting/fearful of new foods. Although there was some evidence to suggest that children with PKU aged ≥4 years prefer savoury foods (vegetables) more than control children, they did not prefer bitter-tasting foods, and so early and persistent administration of bitter-tasting l-amino acids was not associated with apparent taste imprinting. Neophobia appears to play significant part in food refusal in PKU, perhaps more so than taste preferences. © 2015 The British Dietetic Association Ltd.

    The current view of the control of food intake involves a central feeding system in the hypothalamus receiving input from peripheral systems. The presence of food in the gut stimulates the release of several regulatory peptides that control gut motility and secretion. Some of these peptides also act as feedback satiety signals, responsible for termination of a meal. Among the regulatory peptides suggested as peripheral satiety signals are cholecystokinin and gastrin releasing peptide. A more long-term peripheral regulation of food intake has also been postulated and leptin has been suggested as a regulator of food intake. Several regulatory peptides mediate orexigenic or anorexigenic effects in the central feeding system. Neuropeptide Y and galanin both act centrally and stimulate the intake of food, while corticotropin releasing factor reduces food intake. At present, most information about the regulation of food intake is gained from mammalian studies and these findings are used as a base for a discussion on the current knowledge of how regulatory peptides control appetite in non-mammalian vertebrates.

    Ensuring food safety is nowadays a top priority of authorities and professional players in the food supply chain. One of the key challenges to determine the safety of food and guarantee a high level of consumer protection is the availability of fast, sensitive and reliable analytical methods to identify specific hazards associated to food before they become a health problem. The limitations of existing methods have encouraged the development of new technologies, among them biosensors. Success in biosensor design depends largely on the development of novel receptors with enhanced affinity to the target, while being stable and economical. Aptamers fulfill these characteristics, and thus have surfaced as promising alternatives to natural receptors. This Review describes analytical strategies developed so far using aptamers for the control of pathogens, allergens, adulterants, toxins and other forbidden contaminants to ensure food safety. The main progresses to date are presented, highlighting potential prospects for the future.

    We aimed to determine the prevalence estimates of binge eating disorder, bulimia nervosa, anorexia nervosa, and food addiction in men with heroin use disorder and a matched sample of control participants. A group of 100 men with heroin use disorder, consecutively admitted to a detoxification and therapy unit, were screened for DSM-5 eating disorders, along with a group of 100 male controls of similar age, education, and body mass index. The Yale Food Addiction Scale (YFAS), the Barratt Impulsivity Scale-version 11, and the Eating Attitudes Test were used for data collection. Patients were also evaluated for various aspects of heroin use disorder (e.g., craving) using the Addiction Profile Index. Binge eating disorder that met DSM-5 criteria was more prevalent in patients with heroin use disorder (21%) than in control subjects (8%) (odds ratio 3.1, 95% confidence interval 1.3-7.3; p Food addiction based on the YFAS was also more common among men with heroin use disorder (28%) than among control participants (12%) (odds ratio 2.9, 95% confidence interval 1.4-6.1; p food addiction was associated with more severe craving and having a history of suicide attempts in the patients. Co-occurring binge eating disorder and food addiction are highly frequent in men with heroin use disorder. Screening for binge eating disorder and food addiction in patients with substance use disorder is important, as interventions may improve treatment outcome in this patient group.

    The recent discovery of the presence of variable amounts of the carcinogenic compound acrylamide in a wide range of severely heat-treated food products, such as fried potatoes, biscuits, bread and coffee or malt, as a result of the heat process, has induced an important research in the area of the Maillard reaction in food. The interaction between a specific food composition and the heat process applied results in the development of complex oxidation and glycation reactions, which give rise to a mixture of flavoured compounds and possible neoformed contaminants (NFC). Recommendations by the European Commission aim at monitoring the content of major NFC, such as acrylamide and furan, in a list of food products commercialized in Europe. On the other hand, the Commission for European Normalization (CEN) has created recently a new workgroup (WG13) responsible for normalization of analytical method for NFC assessment. The European collective research ICARE was carried out to identify the possible health consequences of the ingestion of heat-treated products, characterize the reaction kinetics leading to NFC and evaluate some mitigation procedures proposed by the CIAA toolbox, and finally develop a simple, rapid and non destructive control method based on fluorescence acquisition on the crushed food products and chemometric analysis of the spectral information. This paper summarizes the objectives and essential results obtained in the scope of the project, highlighting the need for evaluating the distribution of NFC in food products commercialized in Europe, as well as the impact of the food formula/recipe and process on Maillard derived NFC food levels. The potential of the Fluoralys sensor regarding its ability to control food contamination with NFC is presented. A decrease in NFC concentration of heat processed food should allow significantly limiting the exposure of populations to NFC and consequently the potential related health risk.

    Full Text Available Abstract Background Eating disorders are multifactorial psychiatric disorders. Chronic stressful experiences and caloric restriction are the most powerful triggers of eating disorders in human and animals. Although compulsive behavior is considered to characterize pathological excessive food intake, to our knowledge, no evidence has been reported of continued food seeking/intake despite its possible harmful consequences, an index of compulsive behavior. Brain monoamine transmission is considered to have a key role in vulnerability to eating disorders, and norepinephrine in medial prefrontal cortex has been shown to be critical for food-related motivated behavior. Here, using a new paradigm of conditioned suppression, we investigated whether the ability of a foot-shock-paired conditioned stimulus to suppress chocolate-seeking behavior was reversed by previous exposure to a food restriction experience, thus modeling food seeking in spite of harmful consequences in mice. Moreover, we assessed the effects of selective norepinephrine inactivation in medial prefrontal cortex on conditioned suppression test in stressed and caloric restricted mice. Results While Control (non food deprived animals showed a profound conditioned suppression of chocolate seeking during presentation of conditioned stimulus, previously food restricted animals showed food seeking/intake despite its possible harmful consequences. Moreover, food seeking in spite of harmful consequences was prevented by selective norepinephrine inactivation, thus showing that prefrontal cortical norepinephrine is critical also for maladaptive food-related behavior. Conclusions These findings indicate that adaptive food seeking/intake can be transformed into maladaptive behaviors and point to "top-down" influence on eating disturbances and to new targets for therapy of aberrant eating behaviors.

  11. Supplemental food that supports both predator and pest: a risk for biological control?

    2015-04-01

    Supplemental food sources to support natural enemies in crops are increasingly being tested and used. This is particularly interesting for generalist predators that can reproduce on these food sources. However, a potential risk for pest control could occur when herbivores also benefit from supplemental food sources. In order to optimize biological control, it may be important to select food sources that support predator populations more than herbivore populations. In this study we evaluated the nutritional quality of four types of supplemental food for the generalist predatory mites Amblyseius swirskii Athias-Henriot and Amblydromalus (Typhlodromalus) limonicus (Garman and McGregor), both important thrips predators, and for the herbivore western flower thrips Frankliniella occidentalis Pergande, by assessing oviposition rates. These tests showed that application of corn pollen, cattail pollen or sterilized eggs of Ephestia kuehniella Zeller to chrysanthemum leaves resulted in three times higher oviposition rates of thrips compared to leaves without additional food. None of the tested food sources promoted predatory mites or western flower thrips exclusively. Decapsulated cysts of Artemia franciscana Kellogg were not suitable, whereas cattail pollen was very suitable for both predatory mites and western flower thrips. In addition, we found that the rate of thrips predation by A. swirskii can be reduced by 50 %, when pollen is present. Nevertheless, application of pollen or Ephestia eggs to a chrysanthemum crop still strongly enhanced the biological control of thrips with A. swirskii, both at low and high release densities of predatory mites through the strong numerical response of the predators. Despite these positive results, application in a crop should be approached with caution, as the results may strongly depend on the initial predator-prey ratio, the nutritional quality of the supplemental food source, the species of predatory mites, the distribution of the

    Full Text Available Food safety is an important topic as large number of consumers has become victim of consuming adulterated foods. As the food safety laws, administration and inspection in Bangladesh do not include monitoring the chain of production and comply the recommendation by Codex Alimentarius Commission (CAC, Sanitary and Phytosanitary (SPS Agreement, and Hazard Analysis Critical Control Point (HACCP System, the government is encouraging the private sector to put the food processing and marketing into the context of standard, cost effectiveness, public health issues and global trade. Recommendations came up for strengthening collaboration between Ministries and stakeholders. Since the public health service cannot combat alone the complex situation, the governmental agencies and academic institutions must work together to delineate many of the problems in food safety, consumers protection and zoonoses. In this paper the profiling force linking safety and quality of foods of animal origin in Bangladesh is highlighted.

  13. Central dopaminergic circuitry controlling food intake and reward: implications for the regulation of obesity.

    Science.gov (United States)

    Vucetic, Zivjena; Reyes, Teresa M

    2010-01-01

    Prevalence of obesity in the general population has increased in the past 15 years from 15% to 35%. With increasing obesity, the coincident medical and social consequences are becoming more alarming. Control over food intake is crucial for the maintenance of body weight and represents an important target for the treatment of obesity. Central nervous system mechanisms responsible for control of food intake have evolved to sense the nutrient and energy levels in the organism and to coordinate appropriate responses to adjust energy intake and expenditure. This homeostatic system is crucial for maintenance of stable body weight over long periods of time of uneven energy availability. However, not only the caloric and nutritional value of food but also hedonic and emotional aspects of feeding affect food intake. In modern society, the increased availability of highly palatable and rewarding (fat, sweet) food can significantly affect homeostatic balance, resulting in dysregulated food intake. This review will focus on the role of hypothalamic and mesolimbic/mesocortical dopaminergic (DA) circuitry in coding homeostatic and hedonic signals for the regulation of food intake and maintenance of caloric balance. The interaction of dopamine with peripheral and central indices of nutritional status (e.g., leptin, ghrelin, neuropeptide Y), and the susceptibility of the dopamine system to prenatal insults will be discussed. Additionally, the importance of alterations in dopamine signaling that occur coincidently with obesity will be addressed.

    Full Text Available OBJECTIVE: The study developed a method for controlling the amount of salt and sodium during food preparation, Controlling Salt and Sodium use During Meal Preparation for food services based on the Hazard Analysis and Critical Control Points principles. METHODS: The method was conceived and perfected during a study case in a commercial food service located in Florianópolis, Santa Catarina, Brazil. Data were collected from technical cards, recipes and measurements during food preparation. The preparations were monitored and compared with criteria about the use of salt and sodium found in the literature. Critical control points were identified and corrective measures were proposed. RESULTS: The result was a method consisting of 9 stages: (1 determination of the sodium content in the ingredients; (2 and 3 analysis of menu planning and sodium content; (4 follow-up of food preparation; (5 estimate of the amount of sodium used in the preparations; (6 and 7 selection and following of the preparations with average- and high-sodium content; (8 definition of the critical points and establishment of corrective actions for the use of salt and sodium; and (9 creation of recommendations for the use of salt and sodium. CONCLUSION: The Controlling Salt and Sodium use During Meal Preparation may contribute to global discussions regarding the reduction of salt and sodium intakes and collaborate for the supply of nutritionally and sensorially appropriate meals with respect to salt and sodium content. It may also help to prevent non-communicable chronic diseases.

  3. Perceived parental food controlling practices are related to obesogenic or leptogenic child life style behaviors.

    2009-08-01

    To better understand whether the parental food controlling practices pressure and restriction to eat are obesity preventing or obesity promoting, this study examined whether these parenting practices are related to other (food or non-food) areas that are generally regarded as obesogenic or leptogenic. Are these foods controlling practices more indicative of obesogenic or leptogenic child life style behaviors? In a sample of 7-12-year-old boys and girls (n = 943) the perceived parental food controlling practices were related to various measures for unhealthy life style. Using factor analysis we assessed whether there is a constellation of lifestyle behaviors that is potentially obesogenic or leptogenic. Remarkably, perceived parental restriction and pressure loaded on two different factors. Perceived parental restriction to eat had a negative loading on a factor that further comprised potential obesogenic child life style behaviors, such as snacking (positive loading), time spend with screen media (television or computer) (positive loadings) and frequency of fruit consumption (negative loading). Perceived parental pressure to eat had a positive loading on a factor that further comprised potential leptogenic life style behaviors such as frequency of eating a breakfast meal and sporting (positive loadings). It is concluded that low perceived parental restriction in regard to food may perhaps be a sign of more uninvolved 'neglecting' or indulgent parenting/obesogenic home environment, whereas high perceived parental pressure to eat may be sign of a more 'concerned' leptogenic parenting/home environment, though more research into style of parenting is needed.

    2010-05-01

    Full Text Available Together with expected implications on food safety, the European Regulation 178/2002 has important consequences shaping the agrifood sector.This regulation gives latitude to operators in front of specific food safety objectives and promotes self-control.Private standards are a way of addressing this problem. The paper shows that as soon as producers and retailers have different private standards, a problem of coordination among operators has to be solved. This coordination is important for the sanitary aims but involves strategic aspects too. The coordination problem is tougher when the standards developed by producers and retailers can be considered as two substitutes, even if each operators considers that a coordination of their practices shall be reached.

  6. Task-Based and Questionnaire Measures of Inhibitory Control Are Differentially Affected by Acute Food Restriction and by Motivationally Salient Food Stimuli in Healthy Adults.

    Adaptive eating behaviors are dependent on an interaction between motivational states (e.g., hunger) and the ability to control one's own behavior (inhibitory control). Indeed, behavioral paradigms are emerging that seek to train inhibitory control to improve eating behavior. However, inhibitory control is a multifaceted concept, and it is not yet clear how different types (e.g., reactive motor inhibition, proactive motor inhibition, reward-related inhibition) are affected by hunger. Such knowledge will provide insight into the contexts in which behavioral training paradigms would be most effective. The present study explored the impact of promoting a "need" state (hunger) together with motivationally salient distracting stimuli (food/non-food images) on inhibitory control in 46 healthy adults. Participants attended two study sessions, once after eating breakfast as usual and once after acute food restriction on the morning of the session. In each session, participants completed questionnaires on hunger, mood and inhibitory control, and undertook task-based measures of inhibitory control, and had physiological measurements (height, weight, and blood glucose) obtained by a researcher. Acute food restriction influenced task-based assessments but not questionnaire measures of inhibitory control, suggesting that hunger affects observable behavioral control but not self-reported inhibitory control. After acute food restriction, participants showed greater temporal discounting (devaluation of future rewards), and subjective hunger and these were inversely correlated with stop accuracy on the stop signal task. Finally, participants generally responded faster when food-related distractor images were presented, compared to non-food images, independent of state. This suggests that although food stimuli motivate approach behavior, stimulus relevance does not impact inhibitory control in healthy individuals, nor interact with motivational state. These findings may provide some

    Double-blind placebo-controlled food challenges are considered the most reliable method to diagnose or rule out food allergy. Despite this, there are few validated challenge recipes available. The present study aimed to validate new recipes for low-dose double-blind placebo-controlled food challenges in school children, by investigating whether there were any sensory differences between the active materials containing cow's milk, hen's egg, soy, wheat or cod, and the placebo materials. The challenge materials contained the same hypoallergenic amino acid-based product, with or without added food allergens. The test panels consisted of 275 school children, aged 8-10 and 14-15 yr, respectively, from five Swedish schools. Each participant tested at least one recipe. Standardized blinded triangle tests were performed to investigate whether any sensory differences could be detected between the active and placebo materials. In our final recipes, no significant differences could be detected between the active and placebo materials for any challenge food (p > 0.05). These results remained after stratification for age and gender. The taste of challenge materials was acceptable, and no unfavourable side effects related to test materials were observed. In summary, these new validated recipes for low-dose double-blinded food challenges contain common allergenic foods in childhood; cow's milk, hen's egg, soy, wheat and cod. All test materials contain the same liquid vehicle, which facilitates preparation and dosing. Our validated recipes increase the range of available recipes, and as they are easily prepared and dosed, they may facilitate the use of double-blind placebo-controlled food challenges in daily clinical practice.

  10. The regulatory pyramid meets the food pyramid: can regulatory theory improve controls on television food advertising to Australian children?

    Science.gov (United States)

    Reeve, Belinda

    2011-09-01

    This article examines whether responsive regulation has potential to improve the regulatory framework which controls free-to-air television advertising to children, so that the regulatory scheme can be used more effectively as a tool for obesity prevention. It presents two apparently conflicting arguments, the first being that responsive regulation, particularly monitoring and enforcement measures, can be used to refine the regulation of children's food advertising. The second argument is that there are limits to the improvements that responsive regulation can achieve, since it is trying to achieve the wrong goal, namely placing controls on misleading or deceptive advertising techniques rather than diminishing the sheer volume of advertisements to which children are exposed. These two positions reflect a conflict between public health experts and governments regarding the role of industry in chronic disease prevention, as well as a broader debate about how best to regulate industry.

  11. Reward, dopamine and the control of food intake: implications for obesity

    The ability to resist the urge to eat requires the proper functioning of neuronal circuits involved in top-down control to oppose the conditioned responses that predict reward from eating the food and the desire to eat the food. Imaging studies show that obese subjects might have impairments in dopaminergic pathways that regulate neuronal systems associated with reward sensitivity, conditioning and control. It is known that the neuropeptides that regulate energy balance (homeostatic processes) through the hypothalamus also modulate the activity of dopamine cells and their projections into regions involved in the rewarding processes underlying food intake. It is postulated that this could also be a mechanism by which overeating and the resultant resistance to homoeostatic signals impairs the function of circuits involved in reward sensitivity, conditioning and cognitive control.

  12. Solar sanitary system (SOL-SAN)

    1996-11-01

    Ordinary composting toilets, because of cooling by evaporation, do not heat the product (humus) hot enough to kill all pathogenic viruses, bacteria, or parasite eggs and cysts. The SOL-SAN system uses direct radiation to pasteurize incoming river water for drinking and also, separately, to pasteurize and dry the humus, and to pasteurize the effluent gray/brown water. Work is in progress on simple fool-proof methods of insuring that the water will not flow out unless it has been pasteurized. Heat exchangers recapture the heat from these very hot pasteurized liquids, thereby warming more in-coming water for washing, which is important for preventing transmission of pathogenic microbes. When pasteurized, the humus and gray/brown water can safely be recycled to fertilize and water the family vegetable garden. Thus no sewer would be needed, and the vegetables or fish would grow well. Widespread use of the SOL-SAN system would save water and nutrients, reduce the prevalence of infectious diseases, improve the nutrition and vitality of the population, and save the large fraction of human food now consumed by parasites.

  13. Predictors of adult humans' self-control and impulsiveness for food reinforcers.

    Humans vary in the degree to which they demonstrate self-control--choice of larger, more delayed over smaller, less delayed reinforcers. When reinforcers consist of food, individual human subjects' choice behavior varies from virtually exclusive self-control to exclusive impulsiveness. The present experiment, using 26 men and 26 women subjects, explored some possible sources of this individual variation through assessing the correlation of behaviors exhibited in the self-control paradigm with various subject characteristics. The results suggest that self-control is negatively related to individuals' reported susceptibility to hunger (Factor 3 of the Three-Factor Eating Questionnaire) and positively related to overall rating of juice desirability, but not to gender or to various measures of caloric deprivation or personality. Relatively high self-perceived levels of food deprivation may decrease self-control, whereas assigning a relatively high value to the reinforcer may increase self-control. Both tendencies would have been adaptive for evolving humans.

    Sanitary challenges negatively affect feed intake and growth, leading to a negative impact on animal well-being and economic losses. The aim of this study was to carry out a meta-analysis to quantify the dynamic feed intake and growth responses of growing pigs after a sanitary challenge. A database was constructed using 122 published experiments reporting the average daily feed intake (ADFI) and the average daily gain (ADG) of pigs subjected to one of six sanitary challenges: digestive bacterial infections, poor housing conditions, lipopolysaccharide (LPS) challenges, mycotoxicoses, parasitic infections and respiratory diseases. The responses to experimental challenges were calculated relative to that of a control group. Statistical analyses were carried out for each challenge to quantify the mean and the dynamic responses in feed intake and growth and to identify the basis of the reduction in growth (i.e. reduction in feed intake or reduction in feed efficiency related to changes in maintenance requirements). All challenges resulted in a reduction in ADFI and ADG, with the strongest responses for mycotoxicoses, respiratory diseases and digestive bacterial infections (8% to 23% reduction in ADFI and 16% to 29% reduction in ADG). The reduction in ADG was linearly related to the reduction in ADFI for digestive bacterial infections, LPS challenge, parasitic infections and respiratory diseases. For poor housing conditions and mycotoxicoses, the relationship was curvilinear. A 10% reduction in ADFI resulted in a reduction in ADG varying from 10% for mycotoxicoses to 43% for digestive bacterial infections. More than 70% of the reduction in ADG could be explained by the reduction in ADFI for mycotoxicoses, LPS challenge and respiratory diseases. For challenges associated with the gastrointestinal tract, a large part of the reduction in ADG was due to an increase in maintenance requirements, suggesting digestive and metabolic changes. A dynamic pattern in the reduction in

    Full Text Available The school canteens are public catering services of great interest as they provide meals to a high number of consumers who are particularly susceptible to health risks, therefore surveillance and health control are very important to ensure food safety. To this purpose, a convention between the Istituto Zooprofilattico Sperimentale of Piemonte Liguria e Valle d’Aosta, and La Spezia municipality was established for the health control of school canteens. In this article we report the results of analysis performed on food and swab surfaces samples collected during the period 2003-2012 in 22 school canteens and 3 cooking centers. From a total of 1187 samples: 313 raw foods were analyzed for chemical and microbiological parameters to verify compliance with legislation, 71 food preparations were analyzed for bacteria indicators to assess the good manufacturing practices, and 803 surface swabs were tested for total mesophilic count (TMC, Salmonella spp. and Listeria spp. to control cleaning/disinfection conditions. The results show that only 1.3% of raw food samples did not respect the limits imposed by legislation, and 1.4% of food preparations was positive for pathogens. In environmental swabs, pathogenic microorganisms were never isolated and TMC exceeded the limits of acceptability in no more than 27% of cases. The most contaminated surfaces were those in contact with food and the equipment difficult to clean. The results demonstrate that potential hazards are kept to acceptable levels in school canteens and cooking centers investigated. In fact, during the period considered no foodborne diseases were reported among users. However, data obtained may be useful to better define control measures to be adopted to improve the hygienic level production in these structures and to prevent foodborne infections.

    Celiac disease (CD) is one of the most common digestive disorders caused by an abnormal immune reaction to gluten. So far there are no available therapies, the only solution is a strict gluten-free diet, which however could be very challenging as gluten can be hidden in many food products. Furthermore an additional problem is related to cross-contamination of nominal gluten-free foods with gluten-based ones during manufacturing. Here we propose a lab on chip platform as a powerful tool to help food manufacturers to evaluate the real amount of gluten in their products by an accurate in-situ control of the production chain and maybe to specify the real gluten content in packages labeling. Our portable gliadin-immunochips, based on an electrochemical impedance spectroscopy transduction method, were first calibrated and then validated for both liquid and solid food matrixes by analyzing different beers and flours. The high specificity of our assay was also demonstrated by performing control experiments on rice and potatoes flours containing prolamin-like proteins. We achieved limit of quantification of 0.5 ppm for gliadin that is 20 times lower than the worldwide limit established for gluten-free food while the method of analysis is faster and cheaper than currently employed ELISA-based methods. Moreover our results on food samples were validated through a mass spectrometry standard analysis.

    Bacteriophages have attracted great attention for application in food biopreservation. Lytic bacteriophages specific for human pathogenic bacteria can be isolated from natural sources such as animal feces or industrial wastes where the target bacteria inhabit. Lytic bacteriophages have been tested in different food systems for inactivation of main food-borne pathogens including Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7, Salmonella enterica, Shigella spp., Campylobacter jejuni and Cronobacter sakazkii, and also for control of spoilage bacteria. Application of lytic bacteriophages could selectively control host populations of concern without interfering with the remaining food microbiota. Bacteriophages could also be applied for inactivation of bacteria attached to food contact surfaces or grown as biofilms. Bacteriophages may receive a generally recognized as safe status based on their lack of toxicity and other detrimental effects to human health. Phage preparations specific for L. monocytogenes, E. coli O157:H7 and S. enterica serotypes have been commercialized and approved for application in foods or as part of surface decontamination protocols. Phage endolysins have a broader host specificity compared to lytic bacteriophages. Cloned endolysins could be used as natural preservatives, singly or in combination with other antimicrobials such as bacteriocins.

    In modern fruit supply chain a common method to trigger ripening is to keep fruits inside special chambers and initiate the ripening process through administration of ethylene. Ethylene is usually administered through cylinders with inadequate control of its final concentration in the chamber. The aim of this study is the development of a new technology to accurately regulate ethylene concentration in the atmosphere where fruits are preserved: a polymeric film, containing an inclusion complex of α-cyclodextrin with ethylene, was developed. The complex was prepared by molecular encapsulation which allows the entrapment of ethylene into the cavity of α-cyclodextrin. After encapsulation, ethylene can be gradually released from the inclusion complex and its release rate can be regulated by temperature and humidity. The inclusion complex was dispersed into a thin polymeric film produced by UV-curing. This method was used because is solvent-free and involves low operating temperature; both conditions are necessary to prevent rapid release of ethylene from the film. The polymeric films were characterized with respect to thermal behaviour, crystalline structure and kinetics of ethylene release, showing that can effectively control the release of ethylene within confined volume.

    Objective To investigate the preventive effect of probiotics on pediatric food allergy. Methods From MEDLINE bibliographical database, we searched and reviewed all randomized controlled trials on the preventive effects of probiotics on pediatric food allergies up to September 2013 and excluded the studies that do not meet inclusion criteria and extracted the data. Meta-analysis for the results of homogenous studies was performed using RevMan 5.0 and the co-effect was pooled by using fixed-effects model of relative risk (RR) ratios. Results Ten trials published between 2007 and 2012 including 2701 cases were included. Meta-analysis based on included data showed that the preventive effect of prenatal and postnatal probiotic supplementation on food allergies was not significant with the RR=0.88 (95%CI:0.76-1.03). Conclusion Present evidences cannot show in unequivocal terms that prenatal and postnatal probiotic supplementation will prevent food allergic diseases.

  1. Can Differentiated Production Planning and Control enable both Responsiveness and Efficiency in Food Production?

    2014-07-01

    Full Text Available This paper addresses the complex production planning and control (PPC challenges in food supply chains. The study illustrates how food producers' traditional make‐to‐stock (MTS approach is not well suited to meet the trends of increasing product variety, higher demand uncertainty, increasing sales of fresh food products and more demanding customers. The paper proposes a framework for differentiated PPC that combines MTS with make‐to‐order (MTO.The framework matches products with the most appropriate PPC approaches and buffering techniques depending on market and product characteristics. The core idea is to achieve more volume flexibility in the production system by exploiting favourable product and market characteristics (high demand predictability, long customer order leadtime allowances and low product perishability. A case study is used to demonstrate how the framework can enable food producers to achieve efficiency in production, inventory and PPC processes – and simultaneously be responsive to market requirements.

    This paper analyzes the Brazilian Sanitary Surveillance System as an arrangement aimed at regulating and reducing health risks associated with consumption of products, use of health services and the environment. Historical, political and tax aspects were considered and their development compared with the National Health Surveillance System, which has received strong international cooperation. The comparison was based on the trajectory of their national systems and related federal agencies, as well as on criteria adopted for decentralization. The central category of analysis is federative coordination and was based on the framework of federalism and intergovernmental relations. The institutional context of health and sanitary surveillance presents strong political competition, instability in the project and probable reduction of the ability of federal coordination after the Pact for Health. The National Sanitary Surveillance System due to its nature of public good and high externality in its field of action requires federal coordination for increasing the regional and local cooperation, also because of the structural heterogeneity of Brazilian municipalities.

    Prior studies have documented a negative relationship between strength of executive control resources (ECRs) and frequency of snack food consumption. However, little is known about what effect environmental cues (restraining versus facilitating) have on the engagement of such control resources. We presented 88 healthy adults with standardized tests of ECRs followed by a bogus taste test for three appetitive snack foods. Participants were randomly assigned to receive instructions to eat the bare minimum to make their ratings ("restraint condition"), eat as much as they like ("facilitation condition") or no special instructions. We surreptitiously measured the weight of food consumed during the taste test. Findings revealed a main effect of treatment condition, such that those in the restraint condition ate significantly less than those in either of the other conditions; however, this main effect was qualified by an ECR by treatment condition interaction. Specifically, those in the facilitation condition showed a strong negative association between ECR strength and amount of food consumed, whereas those in the restraint and control conditions did not. Findings suggest that the effect of ECR strength on consumption of snack food varies substantially by the characteristics of contextual cues.

    Learning how to make healthy eating decisions, (i.e., resisting unhealthy foods and consuming healthy foods), enhances physical development and reduces health risks in children. Although healthy eating decisions are known to be challenging for children, the mechanisms of children's food choice processes are not fully understood. The present study recorded mouse movement trajectories while eighteen children aged 8-13 years were choosing between eating and rejecting foods. Children were inclined to choose to eat rather than to reject foods, and preferred unhealthy foods over healthy foods, implying that rejecting unhealthy foods could be a demanding choice. When children rejected unhealthy foods, mouse trajectories were characterized by large curvature toward an eating choice in the beginning, late decision shifting time toward a rejecting choice, and slowed response times. These results suggested that children exercised greater cognitive efforts with longer decision times to resist unhealthy foods, providing evidence that children require dietary self-control to make healthy eating-decisions by resisting the temptation of unhealthy foods. Developmentally, older children attempted to exercise greater cognitive efforts for consuming healthy foods than younger children, suggesting that development of dietary self-control contributes to healthy eating-decisions. The study also documents that healthy weight children with higher BMIs were more likely to choose to reject healthy foods. Overall, findings have important implications for how children make healthy eating choices and the role of dietary self-control in eating decisions. Published by Elsevier Ltd.

    provide a diagnosis of the sanitary conditions of jam production sites in Cardoso Moreira. The methods involved the application of a questionnaire on basic knowledge of food safety and foodborne illnesses and a checklist to evaluate the processing plants. In total, 11 producers were evaluated. Two producers showed > 76% compliance and were included in group 1, as classified by (ANVISA. Seven producers showed 51%-75% compliance and were included in group 2. Two producers showed < 50% compliance results and poor conditions for jam production and were included in group 3. The results demonstrated the need for training of farmers about good manufacturing practices to ensure product quality and safety.

    In spite of an irradiated food is innocuous for health and that the irradiation process offers great advantages as conservation and hygiene method and it has been recognised by the Agriculture and Health International organizations and although the adequate equipment exists to make this treatment in the majority of countries, an international trade of irradiated foods has not been established and it is that it has to be required that the quality control of the treatment should be regulated by the corresponding authorities and it also should be harmonized with other countries for the commercial interchange. Owing to up to present an identification method of irradiated foods which is validated, the unique quality control for irradiated foods is realized in the irradiation plant, measuring the absorbed dose in products, using dosimetric systems justly calibrated and standardized to be used the adequate for the type of product and dose level which is wanted to be measured for foods mainly for quarantine treatment which is very important to determine that any part of the irradiation system has reached the minimum dose to obtain the technical effect which is desired and that it does not exceed the maximum dose for that the product quality not to be altered.

    Biofilms are sessile microbial aggregates on the interfaces, and they were usually considered as microbial contamination sources in medical care and various industries. We studied the control and application of biofilms formed by food-related microorganisms, and mechanism of the biofilm formation was also investigated. We studied the biofilm formation in mixed cultures using various combinations of two strains of food-related microorganisms. There were various microorganisms that showed decreased or increased biofilm formation in the mixed culture in comparison with that in a single culture. Biofilm formed by lactic acid bacteria and yeast isolated from traditional fermented food, Fukuyama pot vinegar, exhibited unique feature in that structure and formation mechanism, and expected to be used as an immobilized microorganism in fermentation production. Here our studies on the control and application of biofilms and the mechanisms of its formation were described.

    Full Text Available The objective of this research was to evaluate the effects of using different herbicides as desiccants in pre - harvest and the effects of storage on the physiological and sanitary quality of azuki bean seeds ( Vigna angularis Willd. The experiment was arranged in a randomized complete block design in a split plot scheme, with four replications. Four herbicides were tested: paraquat (400 g a.i. ha - 1 , glufosinate ammonium (400 g a.i. ha - 1 , glyphosate (720 g a.i. ha - 1 , flumioxazin (30 g a.i. ha - 1 and a control without herbicide application. In the subplots seed quality was tested in two evaluation periods: at harvest and six months after harvest. Desiccant was applied when the azuki beans were physiologically mature. We assessed the physiological and sanitary quality of the seeds using a vigour and seed health test. The use of glyphosate resulted in a higher incidence of abnormal seedlings and reduced size and weight of the seedlings. With paraquat and flumioxazin the physiological quality was maintained and there was reduced pathogen infestation in the seeds six months after harvest. Storage affected the physiological quality of the azuki bean seeds.

  16. Low control over palatable food intake in rats is associated with habitual behavior and relapse vulnerability: individual differences.

    Johannes W de Jong

    Full Text Available The worldwide obesity epidemic poses an enormous and growing threat to public health. However, the neurobehavioral mechanisms of overeating and obesity are incompletely understood. It has been proposed that addiction-like processes may underlie certain forms of obesity, in particular those associated with binge eating disorder. To investigate the role of addiction-like processes in obesity, we adapted a model of cocaine addiction-like behavior in rats responding for highly palatable food. Here, we tested whether rats responding for highly palatable chocolate Ensure would come to show three criteria of addiction-like behavior, i.e., high motivation, continued seeking despite signaled non-availability and persistence of seeking despite aversive consequences. We also investigated whether exposure to a binge model (a diet consisting of alternating periods of limited food access and access to highly palatable food, promotes the appearance of food addiction-like behavior. Our data show substantial individual differences in control over palatable food seeking and taking, but no distinct subgroup of animals showing addiction-like behavior could be identified. Instead, we observed a wide range extending from low to very high control over palatable food intake. Exposure to the binge model did not affect control over palatable food seeking and taking, however. Animals that showed low control over palatable food intake (i.e., scored high on the three criteria for addiction-like behavior were less sensitive to devaluation of the food reward and more prone to food-induced reinstatement of extinguished responding, indicating that control over palatable food intake is associated with habitual food intake and vulnerability to relapse. In conclusion, we present an animal model to assess control over food seeking and taking. Since diminished control over food intake is a major factor in the development of obesity, understanding its behavioral and neural

    Full Text Available Abstract Background Few studies, if any, have examined the impact of a weight control program on the home food environment in a diverse sample of adults. Understanding and changing the availability of certain foods in the home and food storage practices may be important for creating healthier home food environments and supporting effective weight management. Methods Overweight adults (n = 90; 27% African American enrolled in a 6-month behavioral weight loss program in Vermont and Arkansas. Participants were weighed and completed measures of household food availability and food storage practices at baseline and post-treatment. We examined baseline differences and changes in high-fat food availability, low-fat food availability and the storage of foods in easily visible locations, overall and by race (African American or white participants and region (Arkansas or Vermont. Results At post-treatment, the sample as a whole reported storing significantly fewer foods in visible locations around the house (-0.5 ± 2.3 foods, with no significant group differences. Both Arkansas African Americans (-1.8 ± 2.4 foods and Arkansas white participants (-1.8 ± 2.6 foods reported significantly greater reductions in the mean number of high-fat food items available in their homes post-treatment compared to Vermont white participants (-0.5 ± 1.3 foods, likely reflecting fewer high-fat foods reported in Vermont households at baseline. Arkansas African Americans lost significantly less weight (-3.6 ± 4.1 kg than Vermont white participants (-8.3 ± 6.8 kg, while Arkansas white participants did not differ significantly from either group in weight loss (-6.2 ± 6.0 kg. However, home food environment changes were not associated with weight changes in this study. Conclusions Understanding the home food environment and how best to measure it may be useful for both obesity treatment and understanding patterns of obesity prevalence and health disparity.

    The aim of this study was to develop a molecular technique to determine the level of human originated DNA contamination in unhygienic food products. In the study, four model foods were prepared under both hygienic (H) and non-hygienic (NH) conditions and the human originated microbial loads of these products were determined. DNA was extracted from the model foods and human buccal samples by GIDAGEN Multi-fast DNA isolation kit. A primer specific region of human mitochondrial D-Loop was designed. The level of human DNA contamination in the model foods was determined by real-time PCR. The sensitivity of the technique developed here was 0.00001ng DNA/PCR. In addition, the applicability of the traceable molecular hygiene control method (TMHCM) was tested in 60 food samples from the market. The results of this study demonstrate that DNA based TMHCM can be used to predict to what extent foods meet the human oriented hygienic conditions. Copyright © 2016. Published by Elsevier Ltd.

    Front of pack food labels or signpost labels are currently widely discussed as means to help consumers to make informed food choices. It is hoped that more informed food choices will result in an overall healthier diet. There is only limited evidence, as to which format of a food label is best understood by consumers, helps them best to differentiate between more or less healthy food and whether these changes in perceived healthiness result in changes of food choice. In a randomised experimental study in Hamburg/Germany 420 adult subjects were exposed to one of five experimental conditions: (1) a simple "healthy choice" tick, (2) a multiple traffic light label, (3) a monochrome Guideline Daily Amount (GDA) label, (4) a coloured GDA label and (5) a "no label" condition. In the first task they had to identify the healthier food items in 28 pair-wise comparisons of foods from different food groups. In the second task they were asked to select food portions from a range of foods to compose a one-day's consumption. Differences between means were analysed using ANOVAs. Task I: Experimental conditions differed significantly in the number of correct decisions (p food consumption did not differ significantly between the experimental conditions. Different food label formats differ in the understanding of consumers. The current study shows, that German adults profit most from the multiple traffic light labels. Perceived healthiness of foods is influenced by this label format most often. Nevertheless, such changes in perceived healthiness are unlikely to influence food choice and consumption. Attempts to establish the informed consumer with the hope that informed choices will be healthier choices are unlikely to change consumer behaviour and will not result in the desired contribution to the prevention of obesity and diet related diseases.

    Costa, Michel Iskin da S; Dos Anjos, Lucas

    2016-12-01

    Release of natural enemies to control pest populations is a common strategy in biological control. However, its effectiveness is supposed to be impaired, among other factors, by Allee effects in the biological control agent and by the fact that introduced pest natural enemies interact with some native species of the ecosystem. In this work, we devise a tritrophic food chain model where the assumptions previously raised are proved correct when a hyperpredator attacks the introduced pest natural enemy by a functional response type 2 or 3. Moreover, success of pest control is shown to be related to the release of large amounts (i.e., inundative releases) of natural enemies.

    The Hazard Analysis and Critical Control Point system (HACCP), recommended by different international organizations as the Codex Alimentarius Commission, the World Trade Organization (WTO), the International Office of Epizootics (OIE) and the International Convention for Vegetables Protection (ICPV) amongst others, contributes to ensuring the innocuity of food along the agro-alimentary chain and requires of Good Manufacturing Practices (GMP) for its implementation, GMP's which are legislated in most countries. Since 1997, Colombia has set rules and legislation for application of HACCP system in agreement with international standards. This paper discusses the potential and difficulties of the legislation enforcement and suggests some policy implications towards food safety.

    2011-06-01

    The body size of an organism is governed by genetic and environmental factors. As an environmental factor, food appears to be the most important for body size control in animals. C. elegans worms are usually grown on an E. coli strain OP50. We show that the wild-type worms fed on another E. coli strain HB101 grow 1.6 times as large as those fed on OP50. The regression line representing the relationship between the sizes of worms grown on each food for over 30 mutants was drawn, indicating that small mutants tend to be more affected by the change in food. Mutants for the DAF-2 insulin/IGF-1 receptor and downstream SGK-1, a homolog of the serum- and glucocorticoid-inducible kinase, grow less or little larger on HB101, indicating control of body size by these factors. Results on the suppression of mutations in these factors by a mutation in the DAF-16/FOXO transcription factor indicate both DAF-16-dependent and DAF-16-independent control. Furthermore, we show that the food-dependent body size change is because of a change in cell size that is closely related to the protein content per cell.

  12. Tracking food intake as bites: Effects on cognitive resources, eating enjoyment, and self-control.

    While monitoring food intake is critical for controlling eating, traditional tools designed for this purpose can be impractical when one desires real-time feedback. Further, the act of monitoring can deplete valuable cognitive resources. In response to these concerns, technologies have been developed to aid those wanting to control their food intake. Of note, devices can now track eating in number of bites taken as opposed to more traditional units such as pieces or volume. Through two studies, the current research investigates the effects of tracking food portions at the bite level on cognitive resources, enjoyment of the eating experience, and objective and subjective self-control. Results indicate that using wearable technology to track bite portions, as compared to doing so mentally, (1) reduces cognitive resource depletion, (2) is equally as effective for allowing users to successfully achieve eating goals, and (3) does not reduce enjoyment of the eating experience. These results support the viability of tracking food intake at the bite level, which holds a number of potential implications for eating and weight management.

    A Citizen Science approach was implemented in the laboratory practices of Genetics at the University of Oviedo, related with the engaging topic of Food Control. Real samples of food products consumed by students at home (students as samplers) were employed as teaching material in three different courses of Genetics during the academic year 2014-2015: Experimental Methods in Food Production (MBTA) (Master level), and Applied Molecular Biology (BMA) and Conservation Genetics and Breeding (COMGE) (Bachelor/Degree level). Molecular genetics based on PCR amplification of DNA markers was employed for species identification of 22 seafood products in COMGE and MBTA, and for detection of genetically modified (GM) maize from nine products in BMA. In total six seafood products incorrectly labeled (27%), and two undeclared GM maize (22%) were found. A post-Laboratory survey was applied for assessing the efficacy of the approach for improving motivation in the Laboratory Practices of Genetics. Results confirmed that students that worked on their own samples from local markets were significantly more motivated and better evaluated their Genetic laboratory practices than control students (χ(2)  = 12.11 p = 0.033). Our results suggest that citizen science approaches could not be only useful for improving teaching of Genetics in universities but also to incorporate students and citizens as active agents in food control. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(5):450-462, 2016.

    Full Text Available The paper describes the transformation of the mechanism of quality control for food products in Russia. It is shown that global trends of deregulation have been leaden to shift from state regulation mechanism of self-regulation in Russia. It was assumed that the organization of self-regulation and organizations of consumer rights protection form the basis of social control mechanism. They contribute to standardization, advocate for the interests of bona fide consumers and producers, organize voluntary certification program. However, in fact, in terms of information asymmetry and the weakness of the non-government mechanisms originated in the failure of the system of quality assurance. The authors explained the situation from the standpoint of the institutional approach. We give some recommendations for improving the efficiency of the regulatory system in Russia. In conclusion, the subject-functional diagram showing the mechanism of social control food quality is presented.

    Food insecurity and hunger during childhood are associated with an array of developmental problems in multiple domains, including impulse control problems and violence. Unfortunately, extant research is based primarily on small convenience samples and an epidemiological assessment of the hunger-violence link is lacking. The current study employed data from Wave 1 (2001–2002) and Wave 2 (2004–2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The NESARC is a nationally representative sample of non-institutionalized U.S. residents aged 18 years and older. Participants who experienced frequent hunger during childhood had significantly greater impulsivity, worse self-control, and greater involvement in several forms of interpersonal violence. These effects were stronger among whites, Hispanics, and males. The findings support general theoretical models implicating impulse control problems as a key correlate of crime and violence and add another facet to the importance of ameliorating food neglect in the United States.

    Full Text Available The purpose of the present paper is to highlight some critical situations emerged during the implementation of long-term projects locally managed by Prevention Services, to control some manufacturing companies in Rome and Prato, Central Italy. In particular, some critical issues on the application of selfcontrol in marketing and catering held by Chinese operators are underlined. The study showed serious flaws in preparing and controlling of manuals for good hygiene practice, participating of the consultants among food business operators (FBOs to the control of the procedures. Only after regular actions by the Prevention Services, there have been satisfying results. This confirms the need to have qualified and expert partners able to promptly act among FBOs and to give adequate support to authorities in charge in order to guarantee food safety.

    Sensory information from periodontal mechanoreceptors (PMRs) surrounding the roots of natural teeth is important for optimizing the positioning of food and adjustment of force vectors during precision biting. The present experiment was designed to test the hypothesis; that reduction of afferent inputs from the PMRs, by anesthesia, perturbs the oral fine motor control and related jaw movements during intraoral manipulation of morsels of food. Thirty healthy volunteers with a natural dentition were equally divided into experimental and control groups. The participants in both groups were asked to manipulate and split a spherical candy into two equal halves with the front teeth. An intervention was made by anesthetizing the upper and lower incisors of the experimental group while the control group performed the task without intervention. Performance of the split was evaluated and the jaw movement recorded. The experimental group demonstrated a significant decrease in measures of performance following local anesthesia. However, there was no significant changes in the duration or position of the jaw during movements in the experimental and control group. In conclusion, transient deprivation of sensory information from PMRs perturbs oral fine motor control during intraoral manipulation of food, however, no significant alterations in duration or positions of the jaw during movements can be observed.

    Synthetic biology has significantly advanced the design of mammalian trigger-inducible transgene-control devices that are able to programme complex cellular behaviour. Fruit-based benzoate derivatives licensed as food additives, such as flavours (e.g. vanillate) and preservatives (e.g. benzoate), are a particularly attractive class of trigger compounds for orthogonal mammalian transgene control devices because of their innocuousness, physiological compatibility and simple oral administration. Capitalizing on the genetic componentry of the soil bacterium Comamonas testosteroni, which has evolved to catabolize a variety of aromatic compounds, we have designed different mammalian gene expression systems that could be induced and repressed by the food additives benzoate and vanillate. When implanting designer cells engineered for gene switch-driven expression of the human placental secreted alkaline phosphatase (SEAP) into mice, blood SEAP levels of treated animals directly correlated with a benzoate-enriched drinking programme. Additionally, the benzoate-/vanillate-responsive device was compatible with other transgene control systems and could be assembled into higher-order control networks providing expression dynamics reminiscent of a lap-timing stopwatch. Designer gene switches using licensed food additives as trigger compounds to achieve antagonistic dual-input expression profiles and provide novel control topologies and regulation dynamics may advance future gene- and cell-based therapies.

  20. The application of irradiation to phyto sanitary problems

    1997-12-31

    The first formally adopted regulatory policy for irradiation as a phyto sanitary treatment in the United States was issued in 1989 and was based on Title 7 of the Code of Federal Regulations. These regulations authorized irradiation as a quarantine treatment for papayas intended for movement from the State of Hawaii to the continental United States (U.S.), Guam, Puerto Rico, and the U.S. Virgin Islands. This authorization was specific for commodity, place of origin, and program, but was designed for a complex of three fruit flies rather than a single pest. Routine commercial shipments were never realized under this regulation due to the lack of a treatment facility in Hawaii. However, the authorization has proven useful from the standpoint of beginning to establish policies for irradiation as a phyto sanitary treatment in the United States. The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) remains dedicated to using the most up-to-date, appropriate and least intrusive technology to provide quarantine security. The need for alternative treatments for pests mitigation systems is greater than ever. Global trade pressures and the possible loss of methyl bromide make it imperative that all practical treatment options be explored. Since 1989 irradiation treatment concepts have matured significantly. Technological advances, greater experience, and an increasingly larger body of research indicate that irradiation has important potential as a treatment for quarantine pest problems. It is in this light that PPQ is expanding its regulatory framework, is addressing irradiation treatment options, and is developing comprehensive policy statements intended to facilitate the development and formalization of new treatments for phyto sanitary applications.

    Landfilling is a major option in waste management hierarchy in developing nations. It generates leachate, which has the potential of polluting watercourses. This study analysed the physico-chemical components of leachate from a closed sanitary landfill in Malaysia, in relation to evaluating the toxicological impact on fish species namely Pangasius sutchi S., 1878 and Clarias batrachus L., 1758. The leachate samples were taken from Air Hitam Sanitary Landfill (AHSL) and the static method of acute toxicity testing was experimented on both fish species at different leachate concentrations. Each fish had an average of 1.3 ± 0.2 g wet weight and length of 5.0 ± 0.1 cm. Histology of the fishes was examined by analysing the gills of the response (dead) group, using the Harris haemtoxylin and eosin (H&E) method. Finneys' Probit method was utilized as a statistical tool to evaluate the data from the fish test. The physico-chemical analysis of the leachate recorded pH 8.2 ± 0.3, biochemical oxygen demand 3500 ± 125 mg L(-1), COD 10 234 ± 175 mg L(-1), ammonical nitrogen of 880 ± 74 mg L(-1), benzene 0.22 ± 0.1 mg L(-1) and toluene 1.2 ± 0.4 mg L(-1). The 50% lethality concentration (LC(50)) values calculated after 96 h exposure were 3.2% (v/v) and 5.9% (v/v) of raw leachate on P. sutchi and C. batrachus, respectively. The H&E staining showed denaturation of the nucleus and cytoplasm of the gills of the response groups. Leachate from the sanitary landfill was toxic to both fish species. The P. sutchi and C. batrachus may be used as indicator organisms for leachate pollution in water.

    A challenge for food industry today is to produce minimally processed food, without use of chemical preservatives and little compromise on nutritional status. Lactobacillus acidophilus NCDC 291 can be directly added to food where it enhances shelf life by competing with other microflora (both bacterial and fungal) for food and also by production of antimicrobial metabolites as bacteriocins. Comprehensive studies have demonstrated the in vitro activity of bacteriocins. However their role in preventing fresh food spoilage needs more elucidation. The present study was conducted to evaluate the efficacy of the whole cells of this organism as biopreservative agent against fungi. Four most commonly occurring spoilage fungi were isolated and were identified as Fusarium, Alternaria, Penicillium and Aspergillus. Growth of all of them was inhibited in in vitro studies, (approximately 33-43% decrease in mycelial dry weight basis between test and control). In situ biopreservation of Indian cheese and raw poultry meat was attempted and the colony count of Alternaria was significantly (p < 0.05, Bonferroni Holm) reduced in presence of L. acidophilus. Dip and Keep approach of preservation for Mangifera and Momordica were carried out in which microbial spoilage was not observed up to 6 days.

    Major cities are congested and large sites suitable for landfill development are limited. Methane and other gases are produced at most sanitary landfills and dumps. These gases may migrate horizontally and vertically and have caused fatalities. Monitoring these gases provides data bases for design and construction of safe buildings on and adjacent to landfills. Methods of monitoring include: (1) a portable combustible gas indicator; and (2) glass flasks valved to allow simultaneous exhaust of the flask and aspiration of the sample into the flask. Samples are drawn through tubing from probes as deep as twenty-five feet below the surface.

    As feeding by humans is one of the main food resources to pigeons (Columba livia), there is general agreement that public education that aims to reduce the food base may be the most feasible way to reduce pigeon abundance. However, except for the classic example of Basel, the method has rarely been tested or implemented. We provide results from a 1 year study in the city of Barcelona where we tested the effect of public education on pigeon population abundance and composition. The quantity of food provided by people to pigeons was significantly reduced during the study. Feral pigeon density was reduced by 40% in the two experimental districts, but no variation was detected in the control district. Detailed analyses in one of the districts showed that the reduction was mainly related to the reduction in food availability but not to culling. Pigeons captured at the end of the experiment were larger than at the start of the study, but body condition was reduced. Results show the effectiveness of public information to manage feral pigeon populations in a large city, and that control operations can exert important selection pressure on the population, leading to changes in population composition. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Essential oils (EOs) are gaining great interest as alternatives for harmful synthetic food preservatives. Due to their volatile nature, they could be applied in food packaging to improve food quality and extend shelf-life. To provide long-term effects of EOs by increasing their retention and ensuring controlled release of their components, they could be encapsulated in cyclodextrins (CDs). Herein, the ability of six CDs to retain nine EOs and to bind their individual components was investigated. Retention capacities and binding abilities of CDs were assessed by static headspace-gas chromatography (SH-GC) using a new validated "rapid method". The ability of CDs to generate controlled release systems was examined by multiple headspace extraction (MHE). Finally, radical scavenging activity of free and encapsulated EOs was evaluated. The highest retention capacity toward the studied EOs was obtained for β-CD and its derivatives (69-78%). Also, β-CD and its derivatives showed, with one exception, the highest Kf values for all the studied guests. In addition, encapsulation in CDs reduced the releasing rate of EO components (from 1.43 to 2.43-fold for β-CD/Satureja montana EO used as a model). Furthermore, the inclusion complexes showed higher ABTS(+) scavenging capacity than the free EOs. Results confirmed the usefulness of CDs as encapsulant for EOs and should encourage their application in food and as part of active packaging systems.

Changing food preferences is an important strategy in addressing the obesity epidemic and its accompanying public health risks. However, little is known about how food preferences can be effectively affected and what neural systems support such changes. In this study, we investigated a novel extensive training paradigm where participants chose from specific pairs of palatable junk food items and were rewarded for choosing the items with lower subjective value over higher value ones. In a later probe phase, when choices were made for real consumption, participants chose the lower-valued item more often in the trained pairs compared with untrained pairs. We replicated the behavioral results in an independent sample of participants while they were scanned with fMRI. We found that, as training progressed, there was decreased recruitment of regions that have been previously associated with cognitive control, specifically the left dorsolateral pFC and bilateral parietal cortices. Furthermore, we found that connectivity of the left dorsolateral pFC was greater with primary motor regions by the end of training for choices of lower-valued items that required exertion of self-control, suggesting a formation of a stronger stimulus-response association. These findings demonstrate that it is possible to influence food choices through training and that this training is associated with a decreasing need for top-down frontoparietal control. The results suggest that training paradigms may be promising as the basis for interventions to influence real-world food preferences.

    In western and westernized societies, large portions of the population live in what are considered to be “obesogenic” environments. Among other things, obesogenic environments are characterized by a high prevalence of external cues that are associated with highly palatable, energy-dense foods. One prominent hypothesis suggests that these external cues become such powerful conditioned elicitors of appetitive and eating behavior that they overwhelm the internal, physiological mechanisms that serve to maintain energy balance. The present research investigated a learning mechanism that may underlie this loss of internal relative to external control. In Experiment 1, rats were provided with both auditory cues (external stimuli) and varying levels of food deprivation (internal stimuli) that they could use to solve a simple discrimination task. Despite having access to clearly discriminable external cues, we found that the deprivation cues gained substantial discriminative control over conditioned responding. Experiment 2 found that, compared to standard chow, maintenance on a “western-style” diet high in saturated fat and sugar weakened discriminative control by food deprivation cues, but did not impair learning when external cues were also trained as relevant discriminative signals for sucrose. Thus, eating a western-style diet contributed to a loss of internal control over appetitive behavior relative to external cues. We discuss how this relative loss of control by food deprivation signals may result from interference with hippocampal-dependent learning and memory processes, forming the basis of a vicious-cycle of excessive intake, body weight gain, and progressive cognitive decline that may begin very early in life.

    Stable isotopes can be used to determine the relative trophic positions of biota within a food web, and to improve our understanding of the biomagnification of contaminants. Plants at the base of the food web uptake dissolved organic carbon (DIC) and nitrogen (DIN) for growth, and their tissue reflects the isotopic composition of these sources. Animals then mirror the isotopic composition of the primary producers, as modified by consumer-diet fractionations at successive trophic steps. During 1995-99, we collected algae, macrophyte, invertebrate, and fish samples from 15 USGS sites in the Everglades and analyzed them for d13C and d15N with the goal of characterizing seasonal and spatial differences in food web relations. Carbon isotopes effectively distinguish between two main types of food webs: ones where algae is the dominant base of the food web, which are characteristic of relatively pristine marsh sites with long hydroperiods, and ones where macrophyte debris appears to be a significant source of nutrients, which are apparently characteristic of shorter hydroperiod sites, and nutrient-impacted marshes and canals. There usually is an inverse relation between d13C and d15N of organisms over time, especially in more pristine environments, reflecting seasonal changes in the d13C of DIC and the d15N of DIN. The d13C and d15N of algae also show strong positive correlations with seasonal changes in water levels. This variability is substantially damped up the food chain, probably because of the longer integration times of animals vs. plants. We speculate that these seasonal shifts in water level result in changes in biogeochemical reactions and nutrient levels, with corresponding variations in the d15N and d13C of biota. For example, small changes in water level may change the balance of photosynthesis, bacterial respiration, and atmospheric exchange reactions that control the d13C of DIC. Such changes will probably also affect the d15N of dissolved inorganic N (DIN

    A striking feature of the restricting subtype of anorexia nervosa (AN) is that these patients are extremely successful in restricting their food intake. Possibly, they are highly efficient in avoiding attentional engagement of food cues, thereby preventing more elaborate processing of food cues and thus subsequent craving. This study examined whether patients diagnosed with restrictive eating disorders ('restricting AN-like patients'; N=88) indeed show stronger attentional avoidance of visual food stimuli than healthy controls (N=76). Attentional engagement and disengagement were assessed by means of a pictorial exogenous cueing task, and (food and neutral) pictures were presented for 300, 500, or 1000 ms. In the 500 ms condition, both restricting AN-like patients and healthy controls demonstrated attentional avoidance of high-fat food as indexed by a negative cue-validity effect and impaired attentional engagement with high-fat food, whereas no evidence was found for facilitated disengagement from high-fat food. Within the group of restricting AN-like patients, patients with relatively severe eating pathology showed relatively strong attentional engagement with low-fat food. There was no evidence for attentional bias in the 300 and 1000 ms condition. The pattern of findings indicate that attentional avoidance of high-fat food is a common phenomenon that may become counterproductive in restricting AN-like patients, as it could facilitate their restricted food intake.

    The Food Health Quality Research Program (Investigación de la Calidad Sanitaria de los Alimentos [ICSA]) of the Public Health Agency of Barcelona (Agencia de Salud Pública de Barcelona [ASPB]) was initiated in 1984 to carry out surveillance of certain chemical and microbiological parameters related to the sanitary and safety of foods sold in the city. The present article analyzes the importance of health surveillance and provides details of the uses of the ICSA program. The main aim of this program is to evaluate whether marketed foods comply with the absence and/or established tolerance levels of specific parameters. Nevertheless, the program is able to incorporate or suppress parameters or foods that pose emerging dangers or interests not represented in current legislation. Besides, the program not only obtains a view of the parameters studied at a specific time period in each report, but also accumulates data over time, allowing risk assessment, calculation of dietary intake of contaminants, analysis of tendencies, and evaluation of the effectiveness of regulations to reduce contaminants. The program can also help in the planning of food control programs. The information obtained is disseminated nationally and internationally and is included in dossiers of contaminants issued by national and European health agencies. This demonstrates that a locally-developed surveillance system can have a wider scope and broader objectives and can provide useful information for managers, administrations, economic operators and consumers.

  15. Family environmental factors influencing the developing behavioral controls of food intake and childhood overweight.

    2001-08-01

    Although a large body of research has assessed direct genetic links between parent and child weight status, relatively little research has assessed the extent to which parents (particularly parents who are overweight) select environments that promote overweight among their children. Parents provide food environments for their children's early experiences with food and eating. These family eating environments include parents' own eating behaviors and child-feeding practices. Results of the limited research on behavioral mediators of familial patterns of overweight indicate that parents' own eating behaviors and their parenting practices influence the development of children's eating behaviors, mediating familial patterns of overweight. In particular, parents who are overweight, who have problems controlling their own food intake, or who are concerned about their children's risk for overweight may adopt controlling child-feeding practices in an attempt to prevent overweight in their children. Unfortunately, research reveals that these parental control attempts may interact with genetic predispositions to promote the development of problematic eating styles and childhood overweight. Although the authors have argued that behavioral mediators of family resemblances in weight status, such as parents' disinhibited or binge eating and parenting practices are shaped largely by environmental factors, individual differences in these behaviors also have genetic bases. A primary public health goal should be the development of family-based prevention programs for childhood overweight. The findings reviewed here suggest that effective prevention programs must focus on providing anticipatory guidance on parenting to foster patterns of preference and food selection in children more consistent with healthy diets and promote children's ability to self-regulate intake. Guidance for parents should include information on how children develop patterns of food intake in the family context

    The paper describes a principal scheme of insurance protection organization due to the negative human influences of environmental factors and industrial risks as one of the most effective mechanisms responsible for controlling sanitary-and-epidemiological well-being and human health. It also considers how a voluntary medical collective insurance program and a civil responsibility insurance one are being implemented due to unforeseen damages done to the population's health and how the quality and safety of goods (work, services) are controlled. Organizational, methodic, and normative legal approaches are proposed to developing the population's insurance protection system.

    Insulin and IGF signaling are critical to numerous developmental and physiological processes, with perturbations being pathognomonic of various diseases, including diabetes. Although the functional roles of the respective signaling pathways have been extensively studied, the control of insulin...... production and release is only partially understood. Herein, we show that in Drosophila expression of insulin-like peptides is regulated by neprilysin activity. Concomitant phenotypes of altered neprilysin expression included impaired food intake, reduced body size, and characteristic changes...

  18. The Relationship between Food Intake and Bladder Cancer: A Case Control Study

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Background & aim: Bladder cancer is the second most common cancer of the urinary tract worldwide and the third most common cancer among Iranian males. Despite the relative high incidence of bladder cancer in Iran, no study has examined the relationship between dietary factors and bladder cancer. The aim of the present study was to investigate this relationship. Methods: The present case-control study was carried out on fifty-five patients with bladder cancer and including 110 cancer-free patients as controls. Dietary intake was evaluated using a food frequency questionnaire. To investigate the relationship between food items and bladder cancer, the subjects were classified according to the tertile of food items. The odds ratio was calculated for each tertile and the first tertile was considered as the reference group. Results: Our findings revealed that among food groups, animal fat (OR=19.76, fat (OR=12.92, junk foods (OR=8.1, organ meat (OR=5.47, processed meat (OR=5.34 and sweets (OR=3.62 were involved in the development of bladder cancer. In bladder carcinogenesis, an inverse association was recorded between consumption of low fat dairy products (OR=0.31, yoghurt (OR =0.14, fish (OR = 0.13, specific fruits (OR=0.13 and the development of bladder cancer. Conclusion: Animal products and sources of saturated fat are associated with an increased in risk of bladder cancer. The protective effect of olive oil, specific fruits, vegetables, low-fat dairy fermented was observed to reduce the risk of bladder cancer.

    It is well established that almost all colorectal cancers arise from benign, neoplastic adenomatous polyps. In previous studies, intake of fruits, vegetables and legumes were found to decrease the risk for colorectal adenomas (CRA) and colorectal cancer. This case-control study aimed to evaluate the roles of a variety of foods in contributing to the risk of CRA in Malaysian subjects. One hundred and eighteen subjects were recruited into case (n=59) and control (n=59) groups at Hospital Kuala Lumpur (HKL). A pre-tested quantitative food frequency questionnaire (FFQ) was used to record the types of food items and frequency consumed. Logistic regression was used to determine the crude and adjusted odds ratios of the independent variables. Soy bean and soy products were associated with a reduced risk for CRA (OR = 0.38, 95% CI = 0.15-0.98), while tubers were associated with increase in risk four-fold (OR = 4.14, 95% CI = 1.60-10.70) and red meat intake was found to increase the risk two and a half-fold (OR = 2.51, 95% CI = 1.02-6.28). Higher servings of fruits and vegetables were found to significantly decrease the risk (OR fruits = 0.47, 95% CI = 0.30-0.74; OR vegetables = 0.49, 95% = 0.29-0.80). In conclusion, our data support protective roles for soy, fruits and vegetables in the aetiology of colorectal adenomas and increase in risk in those with high intakes of red meat and tubers. Food intake of an individual may have an influence on one's risk for developing CRA. This finding warrants further investigation before the protective effect of these food items is to be accepted. New studies should explore the possibility of these associations among individuals in the general population especially with regard to different ethnic or other groups in Malaysia with low fruit and vegetable consumption.

  20. The Official Control beyond the Official Control. How To Plan And Schedule Controls Starting From Risk Assessment Along The Agro-Food Supply Chain.

    Every year the Italian Ministry of Health, on the basis of regional data, draws up the "Report on Official Controls" to be submitted to the Parliament. The report contains abundant data, diagrams and charts and illustrates the number and type of official controls (OC) performed by the pertinent Bodies (Ministry of Health, Regional and Local Health Authorities) over the previous year on Food Business Operators (FBO), in accordance with the EC Regulation 882/2004. The trend - which has consolidated over the years - relates to the multiplicity of OC and shows a decrease of such controls compared to an increase in "non-conformities". OC frequency is established by the Regional Authorities on the basis of the categorisation of both a "generic risk" for companies calculated taking into account the probability of occurrence of a "non-conformity", and a "specific" risk, assessed on the basis of the results of the OC actually performed on a given "Operatore del Settore Alimentare" (Food Sector Operator, in Italian: OSA). Thus, categorisation (i.e. the probability of occurrence of non-conformities) is the main driver of the OC scheduling and planning process. We have been asking ourselves whether the current OC planning/scheduling method is still suitable for ensuring food safety in the face of internalisation of the food supply chain. As a matter of fact, food safety is now becoming increasingly variable due to the globalization of consumption where "farm to fork", rather than "border to fork", food safety must be ensured. On the basis of these considerations, a different OC planning /scheduling method is being proposed based on the assessment of risks and the estimation of the occurrence of the same along the agro-food chain.

    We achieve control of deterministic chaos in an ecosystem model, involving three first-order nonlinear differential equations with a control parameter, recently proposed by Hastings and Powell (HP) in order to describe the dynamical behavior of a three-species food chain. After identifying a chaotic attractor corresponding to a particular value of the parameter of this ecological model, we locate periodic saddle orbits embedded in it. By applying the Ott-Grebogi-Yorke (OGY) method of controlling chaos, which introduces small time-dependent perturbations on the system parameter, we stabilize two of the saddle orbits. Furthermore, we check the versatility of the OGY method, as the system behavior is allowed to switch between 'no control' and 'control' about one or other of different stabilized periodic orbits.

    Is there any association between the intake of different food groups and the risk of idiopathic asthenozoospermia? A high intake of processed meat and sweets was positively associated with a higher risk of asthenozoospermia, whereas a high intake of fruits, vegetables, poultry, skim milk and sea foods was associated with a lower risk. A high intake of lipophilic foods like meat products or milk may be negatively associated with semen quality in humans, whereas some fruits or vegetables may maintain or improve semen quality. A case-control study including 72 asthenozoospermic men and 169 normozoospermic men all from infertile couples who underwent face-to-face private interviews, from January 2011 to December 2011. Semen was assessed by volume, sperm concentration, motility and morphology. Usual dietary intakes were assessed using a semi-quantitative food frequency questionnaire. Odds ratios (ORs), 95% confidence intervals (CIs) and evaluation of trends were calculated using logistic regression. The first tertile served as the reference category for regression analyses. After adjusting for potential confounders, the risk of asthenozoospermia was significantly higher in the highest tertiles of processed meat (OR: 2.03, 95% CI: 1.70-2.44) and sweets intake (OR: 2.05, 95% CI: 1.09-2.26). Conversely, being in the highest tertile of total fruits and vegetables, the intake of dark green vegetables, skim milk, poultry and sea food intake was associated with a lower risk of asthenozoospermia (P for trend = 0.04, 0.01, 0.02, 0.03 and 0.04, respectively). Recall bias, selection bias and measurement bias are inevitable in this kind of study and residual confounding due to omission or imprecise measurement of important covariates remains possible. Patients with asthenozoospermia should be advised to adhere to a diet rich in fruits, vegetables, poultry, skim milk and sea foods while low in processed meat and sweets. This study was financially supported by the National Nutrition

    Background Leprosy is remaining prevalent in the poorest areas of the world. Intensive control programmes with multidrug therapy (MDT) reduced the number of registered cases in these areas, but transmission of Mycobacterium leprae continues in most endemic countries. Socio-economic circumstances are considered to be a major determinant, but uncertainty exists regarding the association between leprosy and poverty. We assessed the association between different socio-economic factors and the risk of acquiring clinical signs of leprosy. Methods and Findings We performed a case-control study in two leprosy endemic districts in northwest Bangladesh. Using interviews with structured questionnaires we compared the socio-economic circumstances of recently diagnosed leprosy patients with a control population from a random cluster sample in the same area. Logistic regression was used to compare cases and controls for their wealth score as calculated with an asset index and other socio-economic factors. The study included 90 patients and 199 controls. A recent period of food shortage and not poverty per se was identified as the only socio-economic factor significantly associated with clinical manifestation of leprosy disease (OR 1.79 (1.06–3.02); p = 0.030). A decreasing trend in leprosy prevalence with an increasing socio-economic status as measured with an asset index is apparent, but not statistically significant (test for a trend: OR 0.85 (0.71–1.02); p = 0.083). Conclusions Recent food shortage is an important poverty related predictor for the clinical manifestation of leprosy disease. Food shortage is seasonal and poverty related in northwest Bangladesh. Targeted nutritional support for high risk groups should be included in leprosy control programmes in endemic areas to reduce risk of disease. PMID:21572979

  9. FTO at rs9939609, food responsiveness, emotional control and symptoms of ADHD in preschool children.

    Fleur P Velders

    Full Text Available The FTO minor allele at rs9939609 has been associated with body mass index (BMI: weight (kg/height (m(2 in children from 5 years onwards, food intake, and eating behaviour. The high expression of FTO in the brain suggests that this gene may also be associated with behavioural phenotypes, such as impulsivity and control. We examined the effect of the FTO minor allele (A at rs9939609 on eating behaviour, impulsivity and control in young children, thus before the BMI effect becomes apparent. This study was embedded in the Generation R Study, a population-based cohort from fetal life onwards. 1,718 children of European descent were genotyped for FTO at rs9939609. With logistic regression assuming an additive genetic model, we examined the association between the FTO minor allele and eating behaviour, impulsivity and control in preschool children. There was no relation between FTO at rs9939609 and child BMI at this age. The A allele at rs9939609 was associated with increased food responsiveness (OR 1.21, p = 0.03. Also, children with the A allele were less likely to have symptoms of ADHD (OR 0.74, p = 0.01 and showed more emotional control (OR 0.64, p = 0.01 compared to children without the A allele. Our findings suggest that before the association between FTO and BMI becomes apparent, the FTO minor allele at rs9939609 leads to increased food responsiveness, a decreased risk for symptoms of ADHD and better emotional control. Future studies are needed to investigate whether these findings represent one single mechanism or reflect pleiotropic effects of FTO.

  10. A possible link between BDNF and mTOR in control of food intake

    Full Text Available Food intake is intricately regulated by glucose, amino acids, hormones, neuropeptides, and trophic factors through a neural circuit in the hypothalamus. Brain-derived neurotrophic factor (BDNF, the most prominent neurotrophic factor in the brain, regulates differentiation, maturation, and synaptic plasticity throughout life. Among its many roles, BDNF exerts an anorexigenic function in the brain. However, the intracellular signaling induced by BDNF to control food intake is not fully understood. One candidate for the molecule involved in transducing the anorexigenic activity of BDNF is the mammalian target of rapamycin (mTOR. mTOR senses extracellular amino acids, glucose, growth factors, and neurotransmitters, and regulates anabolic reactions response to these signals. Activated mTOR increases protein and lipid synthesis and inhibits protein degradation. In the hypothalamus, mTOR activation is thought to reduce food intake. Here we summarize recent findings regarding BDNF- and mTOR-mediated feeding control, and propose a link between these molecules in eating behavior.

    French Polynesia has one of the world's highest thyroid cancer incidence rates. A case-control study among native residents of French Polynesia included 229 cases of differentiated thyroid cancer diagnosed between 1979 and 2004, and 371 population controls. Dietary patterns and goitrogenic food consumption (cabbage, cassava) were analyzed. We used a factor analysis to identify dietary patterns and a conditional logistic regression analysis to investigate the association between dietary patterns or food items and thyroid cancer risk. Two distinct dietary patterns were identified: traditional Polynesian and Western. A nonsignificant inverse association was observed between the traditional Polynesian dietary pattern and thyroid cancer risk. The Western pattern was not associated with thyroid cancer risk. Cassava consumption was significantly associated with a decreased risk of thyroid cancer. In conclusion, a traditional Polynesian dietary pattern led to a weak reduced risk of thyroid cancer in French Polynesia. The protective effect of cassava on this cancer does not seem to be substantially different from that of cabbage, which was the main goitrogenic food studied to date.

    In this work we demonstrate that allyl isothiocyanate (AITC), a common food flavoring agent and food preservative, can be effectively captured by and released in a controlled manner from a microporous metal-organic framework (MOF). The extent of AITC-MOF interactions is quantitatively measured by orbital overlap population calculations. Controlled release experiments show that loaded AITC can be released by applying higher relative humidity. Further analysis reveals that the underlying mechanism of the controlled release is associated with the transformation of the MOF from a porous to a nonporous structure at high humidity. This study represents the first example of making use of MOF porosity in food preservation.

    The role of diet in colorectal cancer (CRC) in Jordan has not been studied previously. This study aimed at examining the association between food groups (including grains, fruits, vegetables, milk, and meat and legumes) and CRC risk in Jordan. We compared intakes of the different food groups among CRC patients (n=167) and matched controls (n=240) by age, sex, occupation, and marital status. A validated food frequency questionnaire was used to collect dietary data. Logistic regression was used to evaluate the association of quartiles of intakes of the different food groups with CRC risk. In addition, the association of selected food items with CRC risk was examined. Odds ratios (ORs) for the fourth versus the first quartile of intake were 2.92 [95% confidence interval (CI): 1.40-6.08] for grains, 1.66 (95% CI: 0.81-3.40) for vegetables, 0.55 (95% CI: 0.26-1.16) for fruits, 0.96 (95% CI: 0.46-1.97) for milk, and 1.43 (95% CI: 0.68-2.98) for meat and legumes. In a comparison of the highest with the lowest weekly frequency of consumption, there was a direct association between the risk of CRC and the frequency of consumption of chicken (OR=2.52, 95% CI: 1.33-4.77). An increase in risk was observed with increased consumption of white bread (OR=3.13, 95% CI: 1.18-9.25), whereas consumption of whole bread was associated with a decreased risk for CRC (OR=0.32, 95% CI: 0.12-0.84). Our results support a role of diet in CRC. Direct associations were found for grains, white bread, and chicken, whereas an inverse relation was reported for whole bread.

    Intrauterine growth restriction (IUGR) children are more impulsive towards a sweet reward and have altered feeding behavior in adulthood. We hypothesized that early life inhibitory control predicts feeding behaviors later on in childhood, and the consumption of n-3 PUFAs during infancy may protect IUGR children from developing problematic feeding behaviors. 156 children had information on the Early Childhood Behavior Questionnaire (ECBQ) at 18 months, Food Frequency Questionnaire at 48 months and Children׳s Eating Behavior Questionnaire (CEBQ) at 72 months. There was a significant negative correlation between inhibitory control at 18 months and food fussiness at 72 months. A GLM model predicting food fussiness at 72 months showed significant interaction between n-3 PUFAs, inhibitory control and IUGR, with higher intakes associated with decreased risk for fussiness in IUGR children with poor inhibitory control. Deficits in early inhibitory control predict later food fussiness, and higher intakes of n-3 PUFAs in infancy may protect IUGR children from developing such behavior later.

    The food and medicine industries have been steadily investing facilities for producing new products and improving production efficiency, while coping with the problems associated with superannuated facilities. Fuji Electric has been supplying a new controlling system FOCUS, characterized by its capacity of minimizing cost and openness, since the fall of 1996. It has been adopted by a number of facilities as the monitoring/controlling system, becoming one of the favorite products of the related industries. The FOCUS system developed by the company, which has been supplying a variety of flexible network systems for controlling purposes, easily allows integration of the systems with office LAN`s. This leads to increased proposals for integrated information systems beyond the conventional concept of monitoring/controlling systems, and changed system businesses. (NEDO)

  1. The insular cortex controls food preferences independently of taste receptor signaling

    2012-03-01

    Full Text Available The insular cortex (IC contains the primary sensory cortex for oral chemosensation including gustation, and its integrity is required for appropriate control of feeding behavior. However, it remains unknown whether the role of this brain area in food selection relies on the presence of peripheral taste input. Using multielectrode recordings, we found that the responses of populations of neurons in the IC of freely licking, sweet-blind Trpm5-/- mice are modulated by the rewarding postingestive effects of sucrose. FOS immunoreactivity analyses revealed that these responses are restricted to the dorsal insula. Furthermore, bilateral lesions in this area abolished taste-independent preferences for sucrose that can be conditioned in these Trpm5-/- animals while preserving their ability to detect sucrose. Overall, these findings demonstrate that even in the absence of peripheral taste input, IC regulates food choices based on postingestive signals.

    This paper presents data of a study undertaken to know the sanitary features of water supply (deep pools) for human consumption in the city of Campeche, Mexico. Levels of intestinal bacteria (total and fecal coliforms) were monitored, as well as heterotrophic plate counts and the surroundings of each deep pool were inspected. Each water supply was monitored three times from January to July, 1993 and presented unacceptable levels of heterotrophic plate counts and coliforms which is a strong evidence of fecal contamination of animal or human origin. These findings are a clear indication of unacceptable contamination of water supply for human consumption which requires an improvement and systematic inspection in order to provide good quality water to the population of Campeche.

    A jet inncr-loop bioreactor (JIBR) was used to treat synthetic sanitary sewage with low, medium and high COD load. The experimental resuhs show that it could meet discharge standard at 20-30 min of HRT (hydraulic retention time) for low COD concentration and 60-120 min of HRT for medium and high COD concentration. The maximal COD volume loading and COD sludye loading of 27kg·m-3·d-1 and 5 kg/d per kg MLSS were achieved respectively, that were 10-20 times higher than those of traditional wastewater treatment processes. The BOD5 removal efficiency was more than 90 % and NH1-N more than 85 %. The study on the activity showed that the oxygen consumption rate of the activated times higher than that of the SBR(Sequencing Batch Reactor)and thc dominant bacteria in jet inner-loop bioreactor was Pseudomonas species.

    2012-05-01

    Full Text Available Biological control of fungal plant pathogens can improve global food availability, one of the three pillars of food security, by reducing crop losses, particularly for low-income farmers. However, the interrelationships of many environmental variables can result in multiple interactions among the organisms and their environment, several of which might contribute to effective biological control. Here, we present an advanced survey of the nature and practice of biological control when it is used to control brown rot in stone fruit. Specifically, we describe the population dynamics of Penicillium frequentans and Epicoccum nigrum and their efficacy as biocontrol agents against brown rot disease under field conditions. The size of P. frequentans population after an application of a P. frequentans conidial formulation during the crop season is bigger than that of E. nigrum following the application of an E. nigrum conidial formulation. Moreover, applications of a P. frequentans conidial formulation during the crop season also caused a higher reduction in the number of Monilinia spp. conidia on the fruit surface than that found after applications of an E. nigrum formulation during the growing season.

    Diverse array of food legume crops (Fabaceae: Papilionoideae) have been adopted worldwide for their protein-rich seed. Choice of legumes and their importance vary in different parts of the world. The economically important legumes are severely affected by a range of virus diseases causing significant economic losses due to reduction in grain production, poor quality seed, and costs incurred in phytosanitation and disease control. The majority of the viruses infecting legumes are vectored by insects, and several of them are also seed transmitted, thus assuming importance in the quarantine and in the epidemiology. This review is focused on the economically important viruses of soybean, groundnut, common bean, cowpea, pigeonpea, mungbean, urdbean, chickpea, pea, faba bean, and lentil and begomovirus diseases of three minor tropical food legumes (hyacinth bean, horse gram, and lima bean). Aspects included are geographic distribution, impact on crop growth and yields, virus characteristics, diagnosis of causal viruses, disease epidemiology, and options for control. Effectiveness of selection and planting with virus-free seed, phytosanitation, manipulation of crop cultural and agronomic practices, control of virus vectors and host plant resistance, and potential of transgenic resistance for legume virus disease control are discussed.

  7. Impact of hypothalamic reactive oxygen species in the control of energy metabolism and food intake

    Full Text Available Hypothalamus is a key area involved in the control of metabolism and food intake via the integrations of numerous signals (hormones, neurotransmitters, metabolites from various origins. These factors modify hypothalamic neurons activity and generate adequate molecular and behavioral responses to control energy balance. In this complex integrative system, a new concept has been developed in recent years, that includes reactive oxygen species (ROS as a critical player in energy balance. ROS are known to act in many signaling pathways in different peripheral organs, but also in hypothalamus where they regulate food intake and metabolism by acting on different types of neurons, including proopiomelanocortin (POMC and agouti-related protein (AgRP/neuropeptide Y (NPY neurons. Hypothalamic ROS release is under the influence of different factors such as pancreatic and gut hormones, adipokines (leptin, apelin,..., neurotransmitters and nutrients (glucose, lipids,.... The sources of ROS production are multiple including NADPH oxidase, but also the mitochondria which is considered as the main ROS producer in the brain. ROS are considered as signaling molecules, but conversely impairment of this neuronal signaling ROS pathway contributes to alterations of autonomic nervous system and neuroendocrine function, leading to metabolic diseases such as obesity and type 2 diabetes.In this review we focus our attention on factors that are able to modulate hypothalamic ROS release in order to control food intake and energy metabolism, and whose deregulations could participate to the development of pathological conditions. This novel insight reveals an original mechanism in the hypothalamus that controls energy balance and identify hypothalamic ROS signaling as a potential therapeutic strategy to treat metabolic disorders.

    Thermotolerant Campylobacter spp. rank among the most important foodborne pathogens in Germany. Therefore a necessity for rapid and routinely useable detection methods exists also in the area of food microbiology. A reliable, cultura qualitative, but also quantitative detection of thermotolerant Campylobacter spp. pose a challenge, at least concerning special food matrices, especially because in the context of official food control the cultural detection of thermotolerant Campylobacter spp. is needed. This was the reason, why different cultural detection methods, beside the standard procedure of ISO 10272:2006, in combination with molecular and immunological screening methods were tested at the Bavarian Health and Food Safety Authority (LGL) during the last years for the use in routine diagnostic using different food matrices of animal and plant origin. The results of the comparative studies showed clearly that no enrichment broth tested gave completely satisfactory results for an only culture-based detection the combination with a screening method is therefore recommended for a rapid and reliable detection. But in this case the user should take into account that the sensitivity of such molecular and immunological methods is normally so high that in some cases, depending on the food matrix and processing step, the isolation of the pathogen would not be possible in samples, which were positive in the screening methods.

    The Power of Food Scale (PFS) is a new measure that assesses the drive to consume highly palatable food in an obesogenic food environment. The data reported in this investigation evaluate whether the PFS moderates state cravings, control beliefs, and brain networks of older, obese adults following either a short-term post-absorptive state, in which participants were only allowed to consume water, or a short-term energy surfeit treatment condition, in which they consumed BOOST®. We found that the short-term post-absorptive condition, in which participants consumed water only, was associated with increases in state cravings for desired food, a reduction in participants' confidence related to the control of eating behavior, and shifts in brain networks that parallel what is observed with other addictive behaviors. Furthermore, individuals who scored high on the PFS were at an increased risk for experiencing these effects. Future research is needed to examine the eating behavior of persons who score high on the PFS and to develop interventions that directly target food cravings.

    Understanding the neurobiological substrates that encode learning about food-associated cues and how those signals are modulated is of great clinical importance especially in light of the worldwide obesity problem. Inappropriate or maladaptive responses to food-associated cues can promote over-consumption, leading to excessive energy intake and weight gain. Chronic exposure to foods rich in fat and sugar alters the reinforcing value of foods and weakens inhibitory neural control, triggering learned, but maladaptive, associations between environmental cues and food rewards. Thus, responses to food-associated cues can promote cravings and food-seeking by activating mesocorticolimbic dopamine neurocircuitry, and exert physiological effects including salivation. These responses may be analogous to the cravings experienced by abstaining drug addicts that can trigger relapse into drug self-administration. Preventing cue-triggered eating may therefore reduce the over-consumption seen in obesity and binge-eating disorder. In this review we discuss recent research examining how cues associated with palatable foods can promote reward-based feeding behaviours and the potential involvement of appetite-regulating peptides including leptin, ghrelin, orexin and melanin concentrating hormone. These peptide signals interface with mesolimbic dopaminergic regions including the ventral tegmental area to modulate reactivity to cues associated with palatable foods. Thus, a novel target for anti-obesity therapeutics is to reduce non-homeostatic, reward driven eating behaviour, which can be triggered by environmental cues associated with highly palatable, fat and sugar rich foods.

    2016-05-01

    Objective To outline and discuss the main challenges for sanitary regulation contained in the federal-level Brazilian health policy. Methods For the present qualitative study, based on the analysis of public policies, information was collected from documents and interviews. Document analysis provided a historical overview of the insertion of sanitary regulation into the Brazilian health policy between 1999 and 2009 (first decade of existence of the national health surveillance agency, Anvisa). In addition, 13 interviews were carried out with actors selected for their historical, technical, or academic role in the field. Content analysis was used to define themes emerging from the materials analyzed with a focus on the "content" category, which refers to strategic and operational guidelines of policy programs, projects, initiatives, and normative framework. Results Content analysis revealed five themes that reflect the challenges to sanitary regulation in Brazil: 1) objects under regulation treated as isolated cases; 2) a Brazilian-specific model of sanitary regulation that is different from other international models; 3) ignorance regarding the role of sanitary surveillance in health care; 4) absence of an information system; and 5) absence of performance indicators and assessment tools. Conclusions Sanitary surveillance must have a mission that is disentangled from inspection tasks to become an effective instrument of health protection. For that, an information system that brings the National Sanitary Surveillance System together toward major objectives is essential. The adoption of tools for assessment of action is also required, with the establishment of adequate indicators.

    According to biological and chemical control strategy for pest control, we investigate the dynamics of a predator-prey food chain with impulsive effect, periodic releasing natural enemies and spraying pesticide at different fixed times, by using impulsive differential equation. Choose pest birth rate r{sub 2} as control parameter, we show that there exists a stable pest-eradication periodic solution when r{sub 2} is less than some critical value r{sub 2}* and the system is permanence when r{sub 2} is larger than the critical value r{sub 2}*. By use of standard techniques of bifurcation theory, we prove that above this threshold there are periodic oscillations in prey, middle-predator and top predator. Furthermore, bifurcation diagrams have shown that there exists complexity for the pulsed system including periodic doubling cascade.

    High-throughput screening techniques that analyze the metabolic endpoints of biological processes can identify the contributions of genetic predisposition and environmental factors to the development of common diseases. Studies applying controlled physiological challenges can reveal dysregulation in metabolic responses that may be predictive for or associated with these diseases. However, large-scale epidemiological studies with well controlled physiological challenge conditions, such as extended fasting periods and defined food intake, pose logistic challenges. Culturally and religiously motivated behavioral patterns of life style changes provide a natural setting that can be used to enroll a large number of study volunteers. Here we report a proof of principle study conducted within a Muslim community, showing that a metabolomics study during the Holy Month of Ramadan can provide a unique opportunity to explore the pre-prandial and postprandial response of human metabolism to nutritional challenges. Up to five blood samples were obtained from eleven healthy male volunteers, taken directly before and two hours after consumption of a controlled meal in the evening on days 7 and 26 of Ramadan, and after an over-night fast several weeks after Ramadan. The observed increases in glucose, insulin and lactate levels at the postprandial time point confirm the expected physiological response to food intake. Targeted metabolomics further revealed significant and physiologically plausible responses to food intake by an increase in bile acid and amino acid levels and a decrease in long-chain acyl-carnitine and polyamine levels. A decrease in the concentrations of a number of phospholipids between samples taken on days 7 and 26 of Ramadan shows that the long-term response to extended fasting may differ from the response to short-term fasting. The present study design is scalable to larger populations and may be extended to the study of the metabolic response in defined patient

    The food-borne trematodiases are an important group of neglected tropical diseases (NTDs). Over 40 million people are infected with food-borne trematodes and 750 million (>10% of the world's population) are at risk of these NTDs. Here, we review the life cycles, epidemiology, clinical manifestations, pathology and pathogenesis, diagnosis, treatment, and prevention and control of the major food-borne trematodiases in Southeast Asia. We focus particularly on opisthorchiasis caused by Opisthorchis viverrini and clonorchiasis caused by Clonorchis sinensis, which people contract by ingestion of metacercariae in flesh of raw or undercooked freshwater fishes, on fascioliasis caused by Fasciola species, where infection arises from ingestion of metacercariae on water plants such as watercress, and on Paragonimus species, the lung flukes, which use freshwater crabs and other crustaceans as intermediate hosts. We also include information on the intestinal flukes Fasciolopsis buski, the echinostomes and the so-called 'minute intestinal flukes' of the family Heterophyidae. Ecological information, placing emphasis on reservoir hosts, intermediate snail hosts and secondary hosts where applicable, is also reviewed and research needs are highlighted.

    Neuroendocrine circuits encode environmental information via changes in gene expression and other biochemical activities to regulate physiological responses. Previously, we showed that daf-7 TGFβ and tph-1 tryptophan hydroxylase expression in specific neurons encode food abundance to modulate lifespan in Caenorhabditis elegans, and uncovered cross- and self-regulation among these genes (Entchev et al., 2015). Here, we now extend these findings by showing that these interactions between daf-7 and tph-1 regulate redundancy and synergy among neurons in food encoding through coordinated control of circuit-level signal and noise properties. Our analysis further shows that daf-7 and tph-1 contribute to most of the food-responsiveness in the modulation of lifespan. We applied a computational model to capture the general coding features of this system. This model agrees with our previous genetic analysis and highlights the consequences of redundancy and synergy during information transmission, suggesting a rationale for the regulation of these information processing features.

    2017-01-01

    Many physiological processes fluctuate throughout the day/night and daily fluctuations are observed in brain and peripheral levels of several hormones, neuropeptides and transmitters. In turn, mediators under the “control” of the “master biological clock” reciprocally influence its function. Dysregulation in the rhythmicity of hormone release as well as hormone receptor sensitivity and availability in different tissues, is a common risk-factor for multiple clinical conditions, including psychiatric and metabolic disorders. At the same time circadian rhythms remain in a strong, reciprocal interaction with the hypothalamic-pituitary-adrenal (HPA) axis. Recent findings point to a role of circadian disturbances and excessive stress in the development of obesity and related food consumption and metabolism abnormalities, which constitute a major health problem worldwide. Appetite, food intake and energy balance are under the influence of several brain neuropeptides, including the orexigenic agouti-related peptide, neuropeptide Y, orexin, melanin-concentrating hormone and relaxin-3. Importantly, orexigenic neuropeptide neurons remain under the control of the circadian timing system and are highly sensitive to various stressors, therefore the potential neuronal mechanisms through which disturbances in the daily rhythmicity and stress-related mediator levels contribute to food intake abnormalities rely on reciprocal interactions between these elements.

    by applying two main optimization strategies to traditional refrigeration systems. The first strategy is a new defrost-on-demand scheme, which based on an objective function between quality loss and energy consumption, continuously seeks an optimal time interval for defrosting in dynamic situation. The second...... strategy is through utilization of the thermal mass of the refrigerated foodstuffs, the day-night temperature variation and the capacity control of the compressor, to realize a trade-off between system energy consumption and food quality loss....

    Background: Nutrition labeling is a prominent policy to promote healthy eating.Objective: We aimed to evaluate the effects of 2 interpretive nutrition labels compared with a noninterpretive label on consumer food purchases.Design: In this parallel-group randomized controlled trial, we enrolled household shoppers across New Zealand who owned smartphones and were aged ≥18 y. Eligible participants were randomly assigned (1:1:1) to receive either traffic light labels (TLLs), Health Star Rating labels (HSRs), or a control [nutrition information panel (NIP)]. Smartphone technology allowed participants to scan barcodes of packaged foods and to receive allocated labels on their smartphone screens. The primary outcome was the mean healthiness of all packaged food purchases over the 4-wk intervention period, which was measured by using the Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (NPSC).Results: Between October 2014 and November 2015, 1357 eligible shoppers were randomly assigned to TLL (n = 459), HSR (n = 443), or NIP (n = 455) labels. Overall difference in the mean transformed NPSC score for the TLL group compared with the NIP group was -0.20 (95% CI: -0.94, 0.54; P = 0.60). The corresponding difference for HSR compared with NIP was -0.60 (95% CI: -1.35, 0.15; P = 0.12). In an exploratory per-protocol analysis of participants who used the labeling intervention more often than average (n = 423, 31%), those who were assigned to TLL and HSR had significantly better NPSC scores [TLL compared with NIP: -1.33 (95% CI: -2.63, -0.04; P = 0.04); HSR compared with NIP: -1.70 (95% CI: -2.97, -0.43; P = 0.01)]. Shoppers who were randomly assigned to HSR and TLL also found the labels significantly more useful and easy to understand than the NIP (all P values NIP users, frequent TLL and HSR users had significantly healthier food purchases.

    Research conducted with adults suggests that successful weight losers demonstrate greater activation in brain regions associated with executive control in response to viewing high-energy foods. No previous studies have examined these associations in adolescents. Functional neuroimaging was used to assess brain response to food images among groups of overweight (OW), normal-weight (NW), and successful weight-losing (SWL) adolescents. Eleven SWL, 12 NW, and 11 OW participants underwent functional magnetic resonance imaging while viewing images of high- and low-energy foods. When viewing high-energy food images, SWLs demonstrated greater activation in the dorsolateral prefrontal cortex (DLPFC) compared with OW and NW controls. Compared with NW and SWL groups, OW individuals demonstrated greater activation in the ventral striatum and anterior cingulate in response to food images. Adolescent SWLs demonstrated greater neural activation in the DLPFC compared with OW/NW controls when viewing high-energy food stimuli, which may indicate enhanced executive control. OW individuals' brain responses to food stimuli may indicate greater reward incentive processes than either SWL or NW groups. © 2015 The Obesity Society.

The animals were also pretreated with saline icv (SAL or SR59230A (50 nmol followed by BRL37344 (20 nmol or SAL in order to determine the selectivity of the effects evoked by BRL37344 on food intake or the selectivity of the effects evoked by SR59230A on risk assessment (RA behavior. The highest dose of BRL37344 (N = 7 decreased food intake 1 h after the treatment (6.4 ± 0.5 g in SAL-treated vs 4.2 ± 0.8 g in drug-treated rats. While both doses of SR59230A failed to affect food intake (5.1 ± 1.1 g for 10 nmol and 6.0 ± 1.8 g for 50 nmol, this treatment reduced the RA frequency (number/30 min (4 ± 2 for SAL-treated vs 1 ± 1 for 10 nmol and 0.5 ± 1 for 50 nmol SR59230A-treated rats, an ethological parameter related to anxiety. While pretreatment with SR59230A (7.0 ± 0.5 g abolished the hypophagia induced by BRL37344 (3.6 ± 0.9 g, BRL37344 suppressed the reduction in RA frequency caused by SR59230A. These results show that the hypophagia caused by BRL37344 is selectively mediated by β3-adrenergic receptors within the central nervous system. Moreover, they suggest the involvement of these receptors in the control of anxiety.

    The U.S. food and beverage industry recently released a new front-of-package nutrition labeling system called Facts Up Front that will be used on thousands of food products. To test consumer understanding of the Facts Up Front system (Facts Up Front) compared to the Multiple Traffic Light system (Traffic Light). Facts Up Front displays grams/milligrams and percentage daily value information for various nutrients; Traffic Light uses an interpretive color-coded scheme to alert consumers to low, medium, and high levels of certain nutrients. Participants in an Internet-based study were randomized to one of five front-of-package label conditions: (1) no label; (2) Traffic Light; (3) Traffic Light plus information about protein and fiber (Traffic Light+); (4) Facts Up Front; or (5) Facts Up Front plus information about "nutrients to encourage" (Facts Up Front+). A total of 703 adults recruited through an online database in May 2011 participated in this study, and data were analyzed in June 2011. Total percentage correct quiz scores were generated reflecting participants' ability to compare two foods on nutrient levels, based on their labels, and to estimate amounts of saturated fat, sugar, sodium, fiber and protein in the foods. The front-of-package label groups outperformed the control group on nearly all of the nutrient quizzes (pFacts Up Front group on the saturated fat quiz, or from the Facts Up Front+ group on the sugars quiz. Those in the Traffic Light+ group had the best overall performance (>80% on all quizzes). Overall, those in the Traffic Light+ condition performed better than those in the Facts Up Front conditions on measures of nutrition knowledge and label perceptions.

    Full Text Available In Benin, West Africa, frying is one of the major ways of cooking. However, the chemical composition of the oil used in the food frying process contains unsaturated fatty acids and other by-products that compromise the oil quality making it toxic and often carcinogenic. The aim of this study was to check the reliability of kits in controlling three frying yams oil quality. The food frying was performed using oil in a discontinuous heating period of 15 min followed by three hours of cooling period for two experimental days. The temperature, and the oil chemical samplings were assessed with the kit every thirty minutes. In addition, selected oil chemical characteristics were determined to quantitatively and qualitatively appreciate the chemical modifications during the fast food versus the rapid food processing methods. Our findings indicate that water and volatile chemical compounds vary significantly for the first day of analysis from 0.18% to 1.6% for groundnut oil; from 0.14% to 1.4% for palm oil and from 0.17% to 1.6% for cotton oils. We detected a decrease of iodine index to 25%; 35.31% and 27.78% for groundnut, palm and cotton oils respectively. However, the peroxide index increases to 55.33%; 61.90% and 57.78% for groundnut, palm and cotton oils respectively. The increases of acid and saponification indices were also observed. Under conjugated effect of water temperature contained in the yam and air contact, the chemical characteristics of oil vary with the frying time. Our results reveal concordance consistent data with both the rapid methods and laboratory data set analysis.

  6. Narratives of Public Health in Dickens's Journalism: The Trouble with Sanitary Reform.

    Although Dickens is still known as having been a highly visible supporter of England's well-known nineteenth-century sanitary movement, he became, in fact, deeply troubled by many of this movement's fundamental tenets, as evidenced by journal narratives on fever that he edited and wrote in the mid-nineteenth century. Rather than water and sewer engineering works and a sanitary regime policed by government agencies as envisaged by Edwin Chadwick and other sanitary reformers, Dickens's view by 1855 was that only a massive erasure of the existing social and political systems and their replacement by an utterly new infrastructure would suffice.

    Enteric viruses are pathogens associated with food- and waterborne outbreaks. The recovery of viruses from food or water samples is affected by the procedures applied to detect and concentrate them. The incorporation of an internal process control virus to the analyses allows monitoring the performance of the methodology. The aim of this study was to produce a recombinant adenovirus (rAdV) and apply it together with bacteriophage PP7 as process controls. The rAdV carries a DNA construction in its genome to differentiate it from wild-type adenovirus by qPCR. The stability of both control viruses was evaluated at different pH conditions. The rAdV was stable at pH 3, 7, and 10 for 18 h. PP7 infectious particles were stable at pH 7 and showed a 2.14 log reduction at pH 10 and total decay at pH 3 after 18 h. Three virus concentration methods were evaluated: hollow-fiber tap water ultrafiltration, wastewater ultracentrifugation, and elution-PEG precipitation from lettuce. Total and infectious viruses were quantified and their recoveries were calculated. Virus recovery for rAdV and PP7 by ultrafiltration showed a wide range (2.10-84.42 and 13.54-84.62%, respectively), whereas that by ultracentrifugation was 5.05-13.71 and 6.98-13.27%, respectively. The performance of ultracentrifugation to concentrate norovirus and enteroviruses present in sewage was not significantly different to the recovery of control viruses. For detection of viruses from lettuce, genomic copies of PP7 were significantly more highly recovered than adenovirus (14.74-18.82 and 0.00-3.44%, respectively). The recovery of infectious virus particles was significantly affected during sewage ultracentrifugation and concentration from lettuce. The simultaneous use of virus controls with dissimilar characteristics and behaviors might resemble different enteric viruses.

    Full Text Available Staphylococcal food poisoning is one of the most frequent foodborne illnesses worldwide and it is caused by the ingestion of food contaminated with enterotoxins produced by some strains of Staphylococcus (S. aureus. In the State of Rio Grande do Sul (RS, Southern Brazil, S. aureus has been identified as the second most frequent agent of foodborne illnesses in the last two decades. The aim of the present study was to assess and analyse the epidemiological data of S. aureus food poisoning occurred in the State of RS during the years of 2000 to 2002. The official records of epidemiological investigations carried out by the Sanitary Surveillance Services of the State of RS were analysed. Among foodborne outbreaks for which aetiology was determined, S. aureus was identified as the responsible agent of 57 foodborne outbreaks, being 42 (74% confirmed by microbiological analyses and 15 (26% confirmed by clinical symptoms and/or epidemiological data. Staphylococcal outbreaks were responsible for the exposition of 5,991 persons, of which 1,940 (32% were interviewed by the Sanitary Surveillance officers. The most affected age group corresponded to people with 20 to 49 years old (48%, where men (48% and women (52% were affected similarly. The main involved food vehicles were meats servings (35%, followed by pastries (25%, cheese (23%, pasta (11% and potato salad with homemade mayonnaise (11%. The majority of the outbreaks occurred inside private homes (33% followed by commercial food establishments (28%. Inadequate control of temperature and failures in general hygiene practices were identified as the main factors responsible for the outbreaks. In conclusion, S. aureus was an important food poisoning etiological agent in the State of RS during 2000 to 2002 and its prevention depends on control measures involving different parts of the food chain.

    Use of additional food has been widely recognized by experimental scientists as one of the important tools for biological control such as species conservation and pest management. The quality and quantity of additional food supplied to the predators is known to play a vital role in the controllability of the system. The present study is continuation of a previous work that highlights the importance of quality and quantity of the additional food in the dynamics of a predator-prey system in the context of biological control. In this article the controllability of the predator-prey system is analyzed by considering inverse of quality of the additional food as the control variable. Control strategies are offered to steer the system from a given initial state to a required terminal state in a minimum time by formulating Mayer problem of optimal control. It is observed that an optimal strategy is a combination of bang-bang controls and could involve multiple switches. Properties of optimal paths are derived using necessary conditions for Mayer problem. In the light of the results evolved in this work it is possible to eradicate the prey from the eco-system in the minimum time by providing the predator with high quality additional food, which is relevant in the pest management. In the perspective of biological conservation this study highlights the possibilities to drive the state to an admissible interior equilibrium (irrespective of its stability nature) of the system in a minimum time.

    Optimising supply chain management can help to reduce food waste. This paper describes how intelligent packaging can be used to reduce food waste when used in supply chain management based on quality-controlled logistics (QCL). Intelligent packaging senses compounds in the package that correlate with the critical quality attribute of a food product. The information on the quality of each individual packaged food item that is provided by the intelligent packaging can be used for QCL. In a conceptual approach it is explained that monitoring food quality by intelligent packaging sensors makes it possible to obtain information about the variation in the quality of foods and to use a dynamic expiration date (IP-DED) on a food package. The conceptual approach is supported by quantitative data from simulations on the effect of using the information of intelligent packaging in supply chain management with the goal to reduce food waste. This simulation shows that by using the information on the quality of products that is provided by intelligent packaging, QCL can substantially reduce food waste. When QCL is combined with dynamic pricing based on the predicted expiry dates, a further waste reduction is envisaged.

    Food allergies affect an estimated 10 to 12 million people in the United States. Some of these individuals can develop life-threatening allergic reactions when exposed to allergenic proteins. At present, the only successful method to manage food allergies is to avoid foods containing allergens. Consumers with food allergies rely on food labels to disclose the presence of allergenic ingredients. However, undeclared allergens can be inadvertently introduced into a food via cross-contact during manufacturing. Although allergen removal through cleaning of shared equipment or processing lines has been identified as one of the critical points for effective allergen control, there is little published information on the effectiveness of cleaning procedures for removing allergenic materials from processing equipment. There also is no consensus on how to validate or verify the efficacy of cleaning procedures. The objectives of this review were (i) to study the incidence and cause of allergen cross-contact, (ii) to assess the science upon which the cleaning of food contact surfaces is based, (iii) to identify best practices for cleaning allergenic foods from food contact surfaces in wet and dry manufacturing environments, and (iv) to present best practices for validating and verifying the efficacy of allergen cleaning protocols.

  12. Science, practice, and human errors in controlling Clostridium botulinum in heat-preserved food in hermetic containers.

    2010-05-01

    The incidence of botulism in canned food in the last century is reviewed along with the background science; a few conclusions are reached based on analysis of published data. There are two primary aspects to botulism control: the design of an adequate process and the delivery of the adequate process to containers of food. The probability that the designed process will not be adequate to control Clostridium botulinum is very small, probably less than 1.0 x 10(-6), based on containers of food, whereas the failure of the operator of the processing equipment to deliver the specified process to containers of food may be of the order of 1 in 40, to 1 in 100, based on processing units (retort loads). In the commercial food canning industry, failure to deliver the process will probably be of the order of 1.0 x 10(-4) to 1.0 x 10(-6) when U.S. Food and Drug Administration (FDA) regulations are followed. Botulism incidents have occurred in food canning plants that have not followed the FDA regulations. It is possible but very rare to have botulism result from postprocessing contamination. It may thus be concluded that botulism incidents in canned food are primarily the result of human failure in the delivery of the designed or specified process to containers of food that, in turn, result in the survival, outgrowth, and toxin production of C. botulinum spores. Therefore, efforts in C. botulinum control should be concentrated on reducing human errors in the delivery of the specified process to containers of food.

    2014-03-13

    Foodborne diseases are typically caused by the ingestion of food contaminated with micro-organisms or their toxins, resulting in gastrointestinal disorders and in some severe cases hospitalization and death. In Brazil, foodborne illnesses are caused mainly by Salmonella, Staphylococcus aureus and Escherichia coli. The most important contributing factors for outbreaks are exposure of foods to unsuitable temperatures, inadequate food preparation and contamination of raw material or water used to prepare food. Recently, aiming to prevent foodborne illnesses during the 2014 FIFA World Cup, Brazil has developed a risk-based evaluation tool able to assess and grade Brazilian food services in cities that will host football matches. This tool has been used by the Brazilian sanitary surveillance officers during the inspection of facilities where food services. This is considered an innovative preventative sanitary action because it was created based on scientific information, statistical calculation and on risks of foodborne diseases occurrence. In this mini-review we summarize general data, control measures and how travellers can prevent foodborne illness in Brazil during the 2014 FIFA World Cup.

    2012-07-01

    Full Text Available Ultimately, the success of augmentative fruit fly biological control depends upon the survival, dispersal, attack rate and multi-generational persistence of mass-reared parasitoids in the field. Foraging for hosts, food and mates is fundamental to the above and, at an operational level, the choice of the parasitoid best suited to control a particular tephritid in a certain environment, release rate estimates and subsequent monitoring of effectiveness. In the following we review landscape-level and microhabitat foraging preferences, host/fruit ranges, orientation through environmental cues, host vulnerabilities/ovipositor structures, and inter and intraspecific competition. We also consider tephritid parasitoid mating systems and sexual signals, and suggest the directions of future research.

    Full Text Available Rheumatoid arthritis (RA is one of the common chronic diseases. Some vegetables and oils may reduce the inflammation in RA and citrus fruits, tomatoes, red meat and salty pickles may worsen the pain and tenderness in joints. The objective of this study is to compare dietary intake of some foods in female RA patients with healthy control group. Materials and Methods: In this case-control study, 44 female RA patients were compared with 41 healthy age-matched controls. Quantitative food frequency questionnaire (FFQ was filled to achieve dietary patterns as interview. The data were analyzed by Kolmogrov-Smirnov and histogram for normality test and Mann U Whitney test for comparing differences between groups using SPSS software version 13.5. Results: mean ± standard deviation of body mass index (BMI was 28.6±3.95 and 28.23±4.32 in RA and control groups respectively. Weekly intake of tomato, cantaloupe, tea and spinach in cases was higher than that of controls (p<0.001 although yogurt (p=0.001, berries (p=0.01, peach (p<0.001, coffee (p<0.001, fast foods (p=0.009, fried foods (p=0.003 and mango (p<0.001 were less common foods in RA patients rather than controls. Conclusion: RA patients had more rate of overweight, but difference between two groups were not significant. The intake of some allergen foods like tomato and cantaloupe was higher in RA patients and some antioxidant-rich foods were eaten less in patients compared with controls so,weight reduction and consumption of more fresh vegetables are recommended.

    Increased education of girls in developing contexts is associated with a number of important positive health, social, and economic outcomes for a community. The event of menarche tends to coincide with girls' transitions from primary to secondary education and may constitute a barrier for continued school attendance and performance. Following the MRC Framework for Complex Interventions, a pilot controlled study was conducted in Ghana to assess the role of sanitary pads in girls' education. A sample of 120 schoolgirls between the ages of 12 and 18 from four villages in Ghana participated in a non-randomized trial of sanitary pad provision with education. The trial had three levels of treatment: provision of pads with puberty education; puberty education alone; or control (no pads or education). The primary outcome was school attendance. After 3 months, providing pads with education significantly improved attendance among participants, (lambda 0.824, F = 3.760, peducation alone improved attendance to a similar level (M = 91.26, SD = 7.82) as sites where pads were provided with puberty education (Rural M = 89.74, SD = 9.34; Periurban M = 90.54, SD = 17.37), all of which were higher than control (M = 84.48, SD = 12.39). The total improvement through pads with education intervention after 5 months was a 9% increase in attendance. After 3 months, providing pads with education significantly improved attendance among participants. The changes in attendance at the end of the trial, after 5 months, were found to be significant by site over time. With puberty education alone resulting in a similar attendance level. This pilot study demonstrated promising results of a low-cost, rapid-return intervention for girls' education in a developing context. Given the considerable development needs of poorer countries and the potential of young women there, these results suggest that a large-scale cluster randomized trial is warranted. Pan African

    Full Text Available BACKGROUND: Recently, operational organizations active in child nutrition in developing countries have suggested that blanket feeding strategies be adopted to enable the prevention of child wasting. A new range of nutritional supplements is now available, with claims that they can prevent wasting in populations at risk of periodic food shortages. Evidence is lacking as to the effectiveness of such preventive interventions. This study examined the effect of a ready-to-use supplementary food (RUSF on the prevention of wasting in 6- to 36-mo-old children within the framework of a general food distribution program. METHODS AND FINDINGS: We conducted a two-arm cluster-randomized controlled pragmatic intervention study in a sample of 1,038 children aged 6 to 36 mo in the city of Abeche, Chad. Both arms were included in a general food distribution program providing staple foods. The intervention group was given a daily 46 g of RUSF for 4 mo. Anthropometric measurements and morbidity were recorded monthly. Adding RUSF to a package of monthly household food rations for households containing a child assigned to the intervention group did not result in a reduction in cumulative incidence of wasting (incidence risk ratio: 0.86; 95% CI: 0.67, 1.11; p = 0.25. However, the intervention group had a modestly higher gain in height-for-age (+0.03 Z-score/mo; 95% CI: 0.01, 0.04; p<0.001. In addition, children in the intervention group had a significantly higher hemoglobin concentration at the end of the study than children in the control group (+3.8 g/l; 95% CI: 0.6, 7.0; p = 0.02, thereby reducing the odds of anemia (odds ratio: 0.52; 95% CI: 0.34, 0.82; p = 0.004. Adding RUSF also resulted in a significantly lower risk of self-reported diarrhea (-29.3%; 95% CI: 20.5, 37.2; p<0.001 and fever episodes (-22.5%; 95% CI: 14.0, 30.2; p<0.001. Limitations of this study include that the projected sample size was not fully attained and that significantly fewer

    The current review considers satiety-based approaches to weight management in the context of health claims. Health benefits, defined as beneficial physiological effects, are what the European Food Safety Authority bases their recommendations on for claim approval. The literature demonstrates that foods that target within-meal satiation and post-meal satiety provide a plausible approach to weight management. However, few ingredient types tested produce the sustainable and enduring effects on appetite accompanied by the necessary reductions in energy intake required to claim satiety/reduction in hunger as a health benefit. Proteins, fibre types, novel oils and carbohydrates resistant to digestion all have the potential to produce beneficial short-term changes in appetite (proof-of-concept). The challenge remains to demonstrate their enduring effects on appetite and energy intake, as well as the health and consumer benefits such effects provide in terms of optimising successful weight management. Currently, the benefits of satiety-enhancing ingredients to both consumers and their health are under researched. It is possible that such ingredients help consumers gain control over their eating behaviour and may also help reduce the negative psychological impact of dieting and the physiological consequences of energy restriction that ultimately undermine weight management. In conclusion, industry needs to demonstrate that a satiety-based approach to weight management, based on single-manipulated food items, is sufficient to help consumers resist the situational and personal factors that drive overconsumption. Nonetheless, we possess the methodological tools, which when employed in appropriate designs, are sufficient to support health claims.

    Interpretive front-of-pack nutrition labels are better understood than non-interpretive labels. However, robust evidence on the effects of such labels on consumer food purchases in the real-world is lacking. Our aim is to assess the effects of two interpretive front-of-pack nutrition labels, compared with a non-interpretive label, on the healthiness of consumer food purchases. A five-week (1-week baseline and 4-week intervention) three-arm parallel randomised controlled trial will be conducted using a bespoke smartphone application, which will administer study questionnaires and deliver intervention (Multiple Traffic Light and Health Star Rating) and control (Nutrition Information Panel) labels. To view their allocated nutrition label, participants scan the barcode of packaged food products using their smartphone camera. The assigned label is displayed instantly on the smartphone screen.1500 eligible participants (New Zealand adult smartphone owners who shop in a supermarket at least once a week and are main household shoppers) will be randomised in a 1:1:1 ratio to one of the three nutrition label formats, using computer-generated randomisation sequences. Randomisation will be stratified by ethnicity and interest in healthy eating. Food and beverage purchase data will be collected continuously throughout the study via hard copy till receipts and electronic grocery purchase lists recorded and transmitted using the smartphone application. The primary outcome will be healthiness of food purchases in each trial arm, assessed as mean Food Standards Australia New Zealand nutrient profiling score criterion score for all food and beverages purchased over the intervention period. Secondary outcomes will include saturated fat, sugar, sodium and energy content of food purchases; food expenditure; labelling profile of food purchases (i.e. mean number of Health Star Rating stars and proportion of red, green and amber traffic lights); nutrient profiling score over time and by

    Full Text Available This investigation has three primary aims: 1 to study the traditional knowledge of Benjarong in Samut Sakhon Province; 2 to study designs and the production process of Benjarong sanitary ware in Samut Sakhon Province; 3 to develop Benjarong sanitary ware for commerce in Samut Sakhon Province. The research area for this investigation was purposively selected as Samut Sakhon Province. Data was gathered by document study, survey, participant and non-participant observation, structured and non-structured interview, focus group discussion and workshop. Results show that Benjarong sanitary products have been inherited from generation to generation in Samut Sakhon Province and continue to provide local jobs. Benjarong sanitary ware production uses a high budget because of the high price of colour inks, gold and electricity, so there are problems securing adequate funding. There are also problems with the management process and a lack of expert craftsmen to write and design modern patterns in harmony with contemporary art and Thai social identity. Moreover, many Thai people do not realize the value of cultural heritage and Benjarong inheritance is at risk. Benjarong sanitary ware can reflect local knowledge and traditional handicrafts. The researchers propose patterns for three types of Benjarong sanitary ware: washbasins, wall tiles and soap ledges. Development of these products will increase functionality and aesthetics, whilst maintaining Thai heritage.

    This study investigated the physiological and psychological effects of sanitary napkins (SN) on women in hemorrhage treatment during the menstrual phase. Mesh and non-woven napkins were employed, and the effects were studied during the follicular and menstrual phases; mesh SN presented a higher textural surface-roughness. In both phases, the increases in systolic and diastolic blood pressure were significantly dependent on the application intervals. The low-frequency component of systolic blood pressure variability significantly increased, while the salivary secretion rate decreased with the use of mesh SN during the follicular phase compared with non-woven SN. In addition, the heart rate during the menstrual phase significantly increased in subjects after the replacement of mesh SN compared with non-woven SN. In cases of wearing the unpleasant mesh SN, electroencephalography (EEG) manifested bilateral enhancements in beta and alpha2 waves in the frontal areas increased arousal level during both phases. From the above findings, napkin use increased physiological loading and wearing napkins with higher textural surface-roughness tended to increase activities of the autonomic nervous system and brain arousal level.

    Many studies have suggested a strong relation between diet and acne. Many patients with acne believe that spicy and salty foods exacerbate acne. To assess the relationship between the dietary intake of salty and spicy food and the onset, severity, duration of acne. Two hundred patients with acne vulgaris and 200 age- and gender-matched controls were subjected to a detailed questionnaire taking, clinical examination and dietary assessment through using "24 h recall" method. Sodium content of the 24-h food intake was computed by a computer program connecting participants' dietary information to the food composition table of National Nutrition Institute data base. Patients with acne consumed significantly higher daily amounts of sodium chloride (NaCl) (median 3367.54 mg) compared to the controls (median 2271.8 mg) (P diet of patients with acne and the age of onset of acne lesions was detected (r = -0.216, P = 0.031). However, neither salty nor spicy food correlated with duration or severity of the disease. Consumption of salty foods was significantly higher among patients with acne compared to acne free subjects, making the consumption of salty food a possible participating factor in the development of acne. © 2015 Wiley Periodicals, Inc.

    The biological actions of growth hormone (GH) are pleiotropic, including growth promotion, energy mobilization, gonadal development, appetite, and social behavior. The regulatory network for GH is complex and includes many central and peripheral endocrine factors as well as that from the environment. It is known that GH transgenesis results in increased growth, food intake, and consequent metabolic rates in fishes. However, the manner in which GH transgenesis alters the energetic metabolism in fishes has not been well explored. In order to elucidate these consequences, we examined the effect of GH overexpression on appetite control mechanisms in a transgenic zebrafish (Danio rerio) model. To this, we analyzed feeding behavior and the expression of the main appetite-related genes in two different feeding periods (fed and fasting) in non-transgenic (NT) and transgenic (T) zebrafish as well as glycaemic parameters of them. Our initial results have shown that NT males and females present the same feeding behavior and expression of main appetite-controlling genes; therefore, the data of both sexes were properly grouped. Following grouped data analyses, we compared the same parameters in NT and T animals. Feeding behavior results have shown that T animals eat significantly more and faster than NT siblings. Gene expression results pointed out that gastrointestinal (GT) cholecystokinin has a substantial contribution to the communication between peripheral and central control of food intake. Brain genes expression analyses revealed that T animals have a down-regulation of two strong and opposite peptides related to food intake: the anorexigenic proopiomelanocortin (pomc) and the orexigenic neuropeptide Y (npy). The down-regulation of pomc in T when compared with NT is an expected result, since the decrease in an anorexigenic factor might keep the transgenic fish hungry. The down-regulation of npy seemed to be contradictory at first, but if we consider the GH's capacity to

    Full Text Available Traditional microbiological methods tend to be labor-intensive and time-consuming. Rapid and novel methods in microbiological tests provide more sensitive, precise and reproducible results compared with conventional methods. In microbiology, the most rapid testing methods belong to the field of biotechnology such as PCR, ELISA, ATP bioluminescence and etc. Nevertheless impedance microbiology, biosensors and analytical procedures to determine microbial constituents are of significance. The present review article was conducted using internet databases and related scientific literatures and articles that provide information on developments in the rapid methods in microbiology. The main focus is on the application of rapid methods in microbial quality control of pharmaceutical products. Reviewed literature showed that rapid methods and automation in microbiology is an advanced area for studying and applying of improved methods in the early detection, and characterization of microorganisms and their products in food, pharmaceutical and cosmetic industrials as well as environmental monitoring and clinical applications. It can be concluded that rapid methods and automation in microbiology should continue as potent and efficient technologies to develop the novel tests to be performed in the future because of the ever-increasing concerns about the safety of food and pharmaceutical products. However the main issues to be considered are the scale up of developed methods and the regulatory requirements.

    One hundred twenty-eight mothers of nasopharyngeal carcinoma (NPC) cases under age 45 in Yulin Prefecture, China and 174 mothers of population controls were interviewed as part of an epidemiological study to examine childhood exposures in relation to the development of NPC. Exposure before age 2 years to a number of fermented foods was a risk factor for NPC. During weaning, intake of salted fish [relative risk (RR) = 2.6, one-sided P (P) = 0.01], salted duck eggs (RR = 5.0, P = 0.03), salted mustard green (RR = 5.4, P = 0.03), and chung choi (RR = 2.0), P = 0.003), a kind of salted root, was significantly related to an increased risk of NPC. Between ages 1 and 2 years, intake frequency of dried fish [P for linear trend test (linear trend P) = 0.002], fermented black bean paste (linear trend P = 0.0009), and fermented soy bean paste (linear trend P = 0.007) was also positively associated with NPC. A multivariate analysis of these different foods showed all except fermented black bean paste to be independently related to NPC.

    Food safety is a critical public concern, and has drawn great attention in society. Consequently, developments of rapid, robust, and accurate methods and techniques for food safety evaluation and control are required. As a nondestructive and convenient tool, near-infrared spectroscopy (NIRS) has been widely shown to be a promising technique for food safety inspection and control due to its huge advantages of speed, noninvasive measurement, ease of use, and minimal sample preparation requirement. This review presents the fundamentals of NIRS and focuses on recent advances in its applications, during the last 10 years of food safety control, in meat, fish and fishery products, edible oils, milk and dairy products, grains and grain products, fruits and vegetables, and others. Based upon these applications, it can be demonstrated that NIRS, combined with chemometric methods, is a powerful tool for food safety surveillance and for the elimination of the occurrence of food safety problems. Some disadvantages that need to be solved or investigated with regard to the further development of NIRS are also discussed.

    The long-term effects of lifestyle changes, diet and medical therapy on obesity are limited. Bariatric surgery is the most effective long-term treatment with the greatest chances for amelioration of obesity-associated complications, including type 2 diabetes mellitus (T2DM). There is increasing evidence in the literature that bariatric operations have a profound effect on human physiology, by reducing hunger, increasing satiety, paradoxically increasing energy expenditure, and even promoting healthy food preferences. Some of these operations improve glucose homeostasis in patients with T2DM independently of weight loss. Changes in the gut hormone levels of glucagon-like peptide 1, peptide YY and ghrelin have been proposed as some of the mediators implicated in changing physiology. The aim of this review is to critically explore the current knowledge on the putative mechanisms of the change in weight and improvement in T2DM glycaemic control after the most commonly performed bariatric operations.

    Full Text Available The objective of this study was to evaluate the hygienic-sanitary conditions of hospital nutrition and dietary services using external and internal auditors. Eleven hospitals were evaluated for their nutrition and dietary services using an evaluation checklist based on food safety requirements in the current legislation. The checklist was applied by an internal auditor (a technical supervisor and an external auditor (a professional with experience in food services between August and October 2011. According to the number of items on the evaluation checklist that were considered adequate, the hospital facilities were ranked as excellent, good, regular, bad, or very bad. The results obtained by the auditors were compared. According to these results, it can be said that most of the hospital nutrition and dietary services were rated as good for overall quality by the internal auditor, while the external auditor classified them as Regular. There was a clear difference between the evaluations of the auditors, both in terms of the number of items considered adequate and the overall requirements' average score. It can be concluded that hospital nutrition and dietary services should meet safety requirements in order to provide food. These facilities should have external audits conducted as a way to prevent routine problems from being perpetuated.

    The influences of selected factors on the generation and recovery of methane gas from sanitary landfills were investigated. The factors included encapsulation, shredding, air classifying, moisture, and pH. Facilities consisting of six model sanitary landfill cells, each with a capacity of approximately 450 cubic yards of municipal waste, and auxiliary subsystems were constructed. Municipal waste in each cell is contained in a 30-mil thick polyvinly chloride plastic sheeting forming a virtually gas-tight envelope. Two cells were filled with as-collected urban waste, two with shredded waste, and two with shredded and air classified waste, constituting three pairs of cells. One of each pair is a control cell with the other used as an experimental variable. Systems were provided for adding measured amounts of water, removing and recirculating leachate, and for extracting gas and measuring gas flow. During testing, gas production and internal cell characteristics were measured to determine the effects of mechanical processing, moisture content, and leachate pH.

    The aim of our study is to evaluate the validity of the "Caregiving×Temperament Paradigm" in the food domain. In this study, two prototypes of caregiving control have been contrasted: Harsh (forceful measures to curve the child's behavior) versus Gentle control (supportive measures to direct the child's behavior). In food domain, the most effective control to help a child to overcome initial dislike is repeated exposure. Our first objective was to test whether the repeated exposure displayed in a gentle context has a more benefical effect on dislike shifting than the one displayed in a harsh context. Our second objective was to assess whether this effect was moderated by a temperamental characteristic (child's inhibitory control). A randomized experimental protocol was used in day care-centers, involving 98 children aged 21-41 months. Children were asked to consume an initially rejected target food on five occasions either with a Gentle or a Harsh instruction. Children's dislike for the target food was assessed via intake before and after the familiarization phase. Inhibitory control level was measured in 78 of these children using validated questionnaire. Four groups were created: Instructions (Gentle vs Harsh)×Inhibitory control (Lower vs Higher). After the familiarization phase, the consumption of the target food increased in all groups, but with a higher increase in children with high Inhibitory control with Gentle instruction, than for children with low Inhibitory control with Harsh instruction, the two other groups being in between. Our data fit a model of cumulative effects, and show that both gentle control strategies and high inhibitory control in children contribute to regulate disgusts experienced in some feeding contexts.

    Hypertension is the leading risk factor for death worldwide, even surpassing tobacco use, high blood glucose, high blood cholesterol, and obesity. Globally, the estimated prevalence of hypertension is nearly 1 billion persons with an annual mortality of almost 7.5 million deaths. In the United States, hypertension affects an estimated 65 million Americans, and is the leading risk-factor cause of death in women and only second to tobacco use as a contributory cause of death in men. Multiple sources of data from prospective observational, cohort, and randomized controlled clinical trials show that hypertension and its complications are highly preventable when the raised blood pressure is prevented, or treated and controlled. To promote positive behavior change and create a broader impact on public health, it has become necessary to leverage multilevel stakeholders such as all health care providers, researchers, policy makers, schools, the food industry, and the general public to drive policy changes and future innovation from research and development endeavors, and to emphasize the importance of diet-related lifestyle modifications to effectively prevent and control hypertension and prehypertension.

    A two-dimensional analytical model for predicting the unsteady temperature field in a cylindrical shaped body affected by spatially varying heat generation is presented. The dimensionless problem is solved analytically by using both partial solutions and the variation of parameters techniques. Having in mind industrial microwave heating for food pasteurization, the easy-to-handle solution is used to confirm the intrinsic lack of spatial uniformity of such a treatment in comparison to the traditional one. From an experimental point of view, a batch pasteurization treatment was realized to compare the effect of two different control techniques both based on IR thermography readout: the former assured a classical PID control, while the latter was based on a "shadowing" technique, consisting in covering portions of the sample which are hot enough with a mobile metallic screen. A measure of the effectiveness of the two control techniques was obtained by evaluating the thermal death curves of a strain Lactobacillus plantarum submitted to pasteurization temperatures. Preliminary results showed meaningful increases in the microwave thermal inactivation of the L. plantarum and similar significant decreases in thermal inactivation time with respect to the traditional pasteurization thermal treatment.

    Restrained eating for weight control and loss is becoming highly prevalent in many affluent societies, while most of the restrained eaters are rather unsuccessful in the long term. According to the strength model of self-control, the disinhibition effect of restrained eaters may occur after the depletion of self-control resources. However, no work has examined the direct impact of self-control resources on inhibitory control ability of restrained eaters. This study investigated the influences of self-control resources on the food-related inhibitory control among high-restraint/low-disinhibition restrained eaters, high-restraint/high-disinhibition restrained eaters and unrestrained eaters using stop signal task. Results reveal that there's no difference of food-related inhibitory control between three groups when the self-control resources are non-depleted, while high-restraint/high-disinhibition restrained eaters showing a decrease of food-related inhibitory control after ego-depletion. This disinhibition effect only seems to occur in samples of restrained eaters with a high tendency toward overeating. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Construction of a system for safety and sanitation control over food manufacturers for export is an essential prerequisite for the manufacturers to register for the record in CIQ or importing countries. It is essential for food manufacturers for export to construct a sound, effective and continuous running system for safety and sanitation to manufacture conforming products. In recent years, aiming at the problems it faces, according to the actual situations, Fujian entry-exit inspection & quarantine bureau has actively explore and practice a new model to construct a system for safety and sanitation control over food manufacturers for export. The manufacturers construct the system for safety and sanitation control for export on the basis of hazard analysis and critical control point (HACCP), improve their management of raw materials by use of supplier measurement system, improve their management by enhancing competency of their managers, and improve consumers’ confidence by use of identification system. So, this new model can insure export food safe and sanitary effectively and be a boost for food manufacturers for export to expand export.%建立出口食品生产企业安全卫生控制体系是出口食品生产企业获得出口食品企业备案或国外注册的必备条件,出口食品企业能否生产符合要求的产品,关键是建立的食品安全卫生控制体系是否健全、是否持续有效运行。近年来,福建出入境检验检疫局针对面临的问题,结合福建出口食品的实际情况,积极探索并实践出一套以危害分析和关键控制点(HACCP)体系为基础,构建出口食品企业安全卫生控制体系;以出口食品企业原料供应商评价体系为载体,完善企业对原料的管理;以促进企业管理人员的能力提升为抓手,全面提高企业整体管理水平;以身份追溯认证系统为切入点,提升消费者信心的出口食品生产企业安全卫生控制体系新

    There is considered the possibility of the use of risk indices with regard to their use in certification and validation of conformity assessment and food conformance, including those recommended for children. There were investigated samples of oatmeals, potted meats, liver pate, fruit-vegetable puree. The calculation of risk values was based on original data of quantitative analysis that was performed with the use of thermogravimetric, photometric, titrimetric, and potentiometric methods, as well as methods of gas-liquid chromatography and atomic absorption spectrophotometry. On the base of data of the chemical analysis of the ingredients of a set of food products, including assigned for baby nutrition, all the tested samples were shown to meet the requirements for the controlled regulatory standards on control indices of quality. The calculation of average daily doses of the intake of metal compounds (Cu, Zn, Fe, Na, Ca, Mg) consumed by adult and child's organisms through tested food showed that such doses are allowable since they do not exceed maximum daily dose and average daily requirements. However, some samples were referred to the category of high risk food, because the used method of individual's lifetime risk calculation takes into consideration all possible negative effects (carcinogenic, mutagenic, teratogenic, embryogenic, etc) of the impact of pollutants on the human body. It is shown that in addition to the sanitary and hygienic criteria of food quality, the risks of such food consumption should be taken into consideration by the Technical Regulations and other normative documentations.

    Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km2. In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    Obiettivi: valutazione della prevalenza di fumatori negli studenti di medicina e di infermieristica al fine di migliorarne le competenze e i comportamenti in tema di tabagismo, in vista anche del loro futuro ruolo nelle Aziende Sanitarie1.

    Materiali e metodi: nell’ambito della Facoltà di Medicina dell’Università di Bologna è stato condotto uno studio sugli aspetti motivazionali e comportamentali delle abitudini al fumo nei giovani iscritti al primo anno di Medicina e di Infermieristica negli AA 1999-2000 e 2002-2003. L’indagine è stata svolta somministrando questionari anonimi agli studenti in aula. Si è ottenuta così una percentuale di rispondenti pari all’ 87 e al 90% della popolazione studentesca iscritta. Risultati: la prevalenza di fumatori cronici o occasionali è andata incrementandosi negli ultimi due anni del 7% tra gli studenti di infermieristica e dell’8,8% tra quelli di medicina, sino a raggiungere rispettivamente il 42,4% e il 25,7%. Nel 2002 il 13,5% dei fumatori ha dichiarato di contemplare la possibilità di smettere entro la fine del corso di studi. Nonostante la giovane età, il 10% di loro erano recidivi da tentativi di disassuefazione falliti.

    Conclusioni: evidente il trend di aumento dell’abitudine al fumo nelle categorie considerate e la difficoltà, a volte notevole, di evitare ricadute nel tabagismo in assenza di adeguato sostegno. Da questi dati è emersa la necessità di impegnarsi per garantire agli studenti sia una più specifica preparazione (si è previsto nel curriculum studi un modulo elective sul tabagismo che una possibilità di disassuefazione precoce, grazie a un canale preferenziale presso il centro per la Disassuefazione dal Fumo di Tabacco dell’ Azienda S.

    Full Text Available The recent rise in obesity is widely attributed to changes in the dietary environment (e.g., increased availability of energy-dense foods and larger portion sizes. However, a critical feature of our "obesogenic environment" may have been overlooked - the dramatic increase in "dietary variability" (the tendency for specific mass-produced foods to be available in numerous varieties that differ in energy content. In this study we tested the hypothesis that dietary variability compromises the control of food intake in humans. Specifically, we examined the effects of dietary variability in pepperoni pizza on two key outcome variables; i compensation for calories in pepperoni pizza and ii expectations about the satiating properties of pepperoni pizza (expected satiation. We reasoned that dietary variability might generate uncertainty about the postingestive effects of a food. An internet-based questionnaire was completed by 199 adults. This revealed substantial variation in exposure to different varieties of pepperoni pizza. In a follow-up study (n= 66; 65% female, high pizza variability was associated with i poorer compensation for calories in pepperoni pizza and ii lower expected satiation for pepperoni pizza. Furthermore, the effect of uncertainty on caloric compensation was moderated by individual differences in decision making (loss aversion. For the first time, these findings highlight a process by which dietary variability may compromise food-intake control in humans. This is important because it exposes a new feature of Western diets (processed foods in particular that might contribute to overeating and obesity.

    Objective To evaluate the association of intake of soya food, a rich source of phytoestrogens, with the risk of endometrial cancer. Design Population based case-control study, with detailed information on usual soya food intake over the past five years collected by face to face interview using a food frequency questionnaire. Setting Urban Shanghai, China. Participants 832 incident cases of endometrial cancer in women aged of 30 to 69 years diagnosed during 1997-2001 and identified from the Shanghai Cancer Registry; 846 control women frequency matched to cases on age and randomly selected from the Shanghai Residential Registry. Main outcome measures Odds ratios for risk of endometrial cancer in women with different intakes of soya foods. Results Regular consumption of soya foods, measured as amount of either soya protein or soya isoflavones, was inversely associated with the risk of endometrial cancer. Compared with women with the lowest quarter of intake, the adjusted odds ratio of endometrial cancer was reduced from 0.93 to 0.85 and 0.67 with increasing quarter of soya protein intake (P for trend 0.01). A similar inverse association was observed for soya isoflavones and soya fibre intake. The inverse association seemed to be more pronounced among women with high body mass index and waist:hip ratio. Conclusion Regular intake of soya foods is associated with a reduced risk of endometrial cancer. PMID:15136343

    Biofilms are microbial communities characterized by their adhesion to solid surfaces and the production of a matrix of exopolymeric substances, consisting of polysaccharides, proteins, DNA and lipids, which surround the microorganisms lending structural integrity and a unique biochemical profile to the biofilm. Biofilm formation enhances the ability of the producer/s to persist in a given environment. Pathogenic and spoilage bacterial species capable of forming biofilms are a significant problem for the healthcare and food industries, as their biofilm-forming ability protects them from common cleaning processes and allows them to remain in the environment post-sanitation. In the food industry, persistent bacteria colonize the inside of mixing tanks, vats and tubing, compromising food safety and quality. Strategies to overcome bacterial persistence through inhibition of biofilm formation or removal of mature biofilms are therefore necessary. Current biofilm control strategies employed in the food industry (cleaning and disinfection, material selection and surface preconditioning, plasma treatment, ultrasonication, etc.), although effective to a certain point, fall short of biofilm control. Efforts have been explored, mainly with a view to their application in pharmaceutical and healthcare settings, which focus on targeting molecular determinants regulating biofilm formation. Their application to the food industry would greatly aid efforts to eradicate undesirable bacteria from food processing environments and, ultimately, from food products. These approaches, in contrast to bactericidal approaches, exert less selective pressure which in turn would reduce the likelihood of resistance development. A particularly interesting strategy targets quorum sensing systems, which regulate gene expression in response to fluctuations in cell-population density governing essential cellular processes including biofilm formation.

    In order to achieve the required air and product temperatures in refrigerated food display cabinets, the evaporator coils, which are normally located in the base of the cabinets, operate at temperatures below the freezing point of water. The air which is circulated over the evaporator coil is cooled below its dew point and water vapour present in the air condenses and eventually freezes on the coil surface. With continuous operation of the coil, frost will accumulate on the coil surface leading to a decrease both in the air flowrate and in the overall heat transfer coefficient. In order to maintain satisfactory performance, evaporator coils are defrosted periodically. Although different defrost control strategies can be employed, for simplicity and cost considerations, defrosting in supermarket refrigeration systems is usually controlled by a pre-set time cycle. It is widely acknowledge, however, that time-based defrost may cause a number of unnecessary defrost cycles and this reduces the energy efficiency of the refrigeration systems as well as the accuracy of temperature control of the cabinets. Implementing defrost only when it is needed or on 'demand' should reduce the number of defrost cycles and lead to savings in energy and improved product quality. This paper reports on field and experimental investigations on the processes of frosting and defrosting of medium-temperature display cabinet evaporator coils. The results show that for medium-temperature refrigeration applications where the environment temperature is kept reasonably constant, the store humidity is the primary parameter influencing the rate of frost formation. Using relative humidity as a control parameter the defrost frequency can be reduced considerably without affecting cabinet performance and product integrity. Alongside the effect of relative humidity, the paper also considers the effects of other performance parameters on the processes of frosting and defrosting such as cooling

    Prion diseases are fatal neurodegenerative diseases that can induce endocrinopathies. The basis of altered endocrine function in prion diseases is not well understood, and the purpose of this study was to investigate the spatiotemporal relationship between energy homeostasis and prion infection in hamsters inoculated with either the 139H strain of scrapie agent, which induces preclinical weight gain, or the HY strain of transmissible mink encephalopathy (TME), which induces clinical weight loss. Temporal changes in body weight, feed, and water intake were measured as well as both non-fasted and fasted concentrations of serum glucose, insulin, glucagon, ??-ketones, and leptin. In 139H scrapie-infected hamsters, polydipsia, hyperphagia, non-fasted hyperinsulinemia with hyperglycemia, and fasted hyperleptinemia were found at preclinical stages and are consistent with an anabolic syndrome that has similarities to type II diabetes mellitus and/or metabolic syndrome X. In HY TME-infected hamsters, hypodipsia, hypersecretion of glucagon (in both non-fasted and fasted states), increased fasted ??-ketones, fasted hypoglycemia, and suppressed non-fasted leptin concentrations were found while feed intake was normal. These findings suggest a severe catabolic syndrome in HY TME infection mediated by chronic increases in glucagon secretion. In both models, alterations of pancreatic endocrine function were not associated with PrPSc deposition in the pancreas. The results indicate that prominent endocrinopathy underlies alterations in body weight, pancreatic endocrine function, and intake of food. The prion-induced alterations of energy homeostasis in 139H scrapie- or HY TME-infected hamsters could occur within areas of the hypothalamus that control food satiety and/or within autonomic centers that provide neural outflow to the pancreas. ?? 2008 Society for Endocrinology.

    This paper describes the trends in the recent fitness club facilities, their institutions as health improving facilities, and their facility management. The recent trend in opening new fitness clubs is characterized by noticeable decrease in new openings of small-scale clubs, and a single club is getting larger in size and fuller in menu line-up. The nationwide distribution of fitness clubs shows concentration in big cities like Tokyo and Osaka. Gymnastic devices, swimming pool, and athletic studios account for overwhelmingly highly in the kinds of facilities. Particularly, warm-water swimming pools have become indispensable, receiving high evaluation as an exercise safe and effective for middle to high aged people in terms of exercise physiology. Important considerations on joining a club are easiness in access, pleasant atmosphere, and high selectivity and cleanliness in facilities. Discontents include poor ventilation, and disagreeable temperature and humidity control. A medical expense deduction system for fitness club utilization based on physicians' prescriptions was inaugurated in 1992. Problems are in improving the quality of sanitary aspects, including air conditioning and air and water filtration in the facilities. 5 figs., 3 tabs.

    Analysis of national health insurance accounts in the Democratic Republic of Congo (DRC) clearly shows the importance of international sanitary aid, particularlyfor thefunding ofgeneral referral hospitals, the management of inpatients with AIDS, administration of health zones andfunding of preventive care providers. It The targeted changes described in this article could possibly optimize the efficiency ofinternational aidfor the DRC population, mainly for disorders considered to be a health care priority (i.e. malaria, AIDS, tuberculosis) as well as in the fight against malnutrition. Recommendations target the implementation of procedures for control offood chain security, changes in lifestyle and dietary habits of the population but also comprise extensive restructuring of the health care administration. A dramatic change of the structure in charge of drug distribution as well as eradication of the transfer of part of public health structure income to public health administrative personnel could result in the allocation of significantfunds to thefight against the most important diseases. Better collaboration between the various departments in charge of health care professional training, together with enhanced responsibility of health care personnel is essential. Independent and respected non-governmental organizations should be involved in an audit process, targeting all aspects of the current DRC health system. Eventually, in an equal opportunity perspective, taking into consideration the very high degree of poverty ofDRC inhabitants, implementation of health insurance programmes, use ofgeneric drugs and generalization ofmicro-credit initiatives should also be implemented.

    Full Text Available ABSTRACT The purpose of this study was to evaluate the effect of the chemical treatment with fungicide, insecticide, micronutrient and polymer on physiological and sanitary quality of soybean seeds during storage. The treatments were arranged in a 3 x 5 x 5 factorial scheme (cultivars x seeds treatment x storage period, in completely randomized design with four replicates. Three cultivars were used: NA 4823RG, BMX TurboRR and Fundacep 62RR. The treatments were: T1: no chemical treatment, T2: fungicide, insecticide and micronutrient; T3: fungicide, insecticide, micronutrient and polymer, T4: fungicide; T5: insecticide. After the chemical treatment, the seeds were stored under environmental conditions from May to December 2012, and seed quality was evaluated at 0, 2, 4, 6 and 8 months of storage. Seeds water content and physiological quality were determined through tests of germination, accelerated aging, seedling length, seedling dry weight and sanity. The treatment with fungicides, insecticides, micronutrients and polymer did not affect seed quality over eight months of storage and promoted the control fungi associated with the seeds.

    Salmonella and Campylobacter are undesirable pathogens on poultry. Therefore the effect of fermented feed on the colonization in the gastro-intestinal tract of the chicken, the introduction of both bacteria in a chicken flocks, and the transmission between chickens was studied. Broilers that were fed with fermented feed were significantly less susceptible for Salmonella and Campylobacter than chickens on a standard chicken feed. The spread of Salmonella between broiler chickens was reduced. However, the results also showed, like for other known control measures, that this feed can not absolutely guarantee the absence of Salmonella and Campylobacter. Therefore fermented feed must be seen as one of the hurdles in a so called multiple hurdle strategy. The combination of different hurdles should prevent the introduction and transmission. The effect of fermented feed on Campylobacter and Salmonella is partially caused by the presence of high concentrations of organic acids. In chickens fed with liquid feed the acidic barrier in the first part of the GI-tract was clearly improved. Besides organic acids there are other changes in the GI-tract. Changes in colonization levels of indicator organisms, changes in levels of organic acids and an increased pH in ileum and ceacum. These changes indicate a stabilised GI-flora in fermented feed fed poultry. The research confirmed that by changes in the composition of the feed (carbohydrates, acids, or micro-organisms) the GI-health can be promoted and therewith can contribute to the control of food pathogens in farmed animals.

    With the still-growing prevalence of obesity worldwide, major efforts are made to understand the various behavioral, environmental, and genetic factors that promote excess fat gain. Obesity results from an imbalance between energy intake and energy expenditure, which emphasizes the importance of deciphering the mechanisms behind energy balance regulation to understand its physiopathology. The control of energy balance is assured by brain systems/circuits capable of generating adequate ingestive and thermogenic responses to maintain the stability of energy reserves, which implies a proper integration of the homeostatic signals that inform about the status of the energy stores. In this article, we overview the organization and functionality of key neuronal circuits or pathways involved in the control of food intake and energy expenditure. We review the role of the corticolimbic (executive and reward) and autonomic systems that integrate their activities to regulate energy balance. We also describe the mechanisms and pathways whereby homeostatic sensing is achieved in response to variations of homeostatic hormones, such as leptin, insulin, and ghrelin, while putting some emphasis on the prominent importance of the mechanistic target of the rapamycin signaling pathway in coordinating the homeostatic sensing process. © 2016 New York Academy of Sciences.

    An analysis of the cost-effectiveness of interventions to control Campylobacter in the New Zealand poultry supply examined a series of interventions. Effectiveness was evaluated in terms of reduced health burden measured by disability-adjusted life years (DALYs). Costs of implementation were estimated from the value of cost elements, determined by discussions with industry. Benefits were estimated by changing the inputs to a poultry food chain quantitative risk model. Proportional reductions in the number of predicted Campylobacter infections were converted into reductions in the burden of disease measured in DALYs. Cost-effectiveness ratios were calculated for each intervention, as cost per DALY reduction and the ratios compared. The results suggest that the most cost-effective interventions (lowest ratios) are at the primary processing stage. Potential phage-based controls in broiler houses were also highly cost-effective. This study is limited by the ability to quantify costs of implementation and assumptions required to estimate health benefits, but it supports the implementation of interventions at the primary processing stage as providing the greatest quantum of benefit and lowest cost-effectiveness ratios.

    Ovarian cancer is the deadliest gynecologic cancer in the US. The consumption of refined sugars has increased dramatically over the past few decades, accounting for almost 15% of total energy intake. Yet, there is limited evidence on how sugar consumption affects ovarian cancer risk. We evaluated ovarian cancer risk in relation to sugary foods and beverages, and total and added sugar intakes in a population-based case-control study. Cases were women with newly diagnosed epithelial ovarian cancer, older than 21 years, able to speak English or Spanish, and residents of six counties in New Jersey. Controls met same criteria as cases, but were ineligible if they had both ovaries removed. A total of 205 cases and 390 controls completed a phone interview, food frequency questionnaire, and self-recorded waist and hip measurements. Based on dietary data, we computed the number of servings of dessert foods, non-dessert foods, sugary drinks and total sugary foods and drinks for each participant. Total and added sugar intakes (grams/day) were also calculated. Multiple logistic regression models were used to estimate odds ratios and 95% confidence intervals for food and drink groups and total and added sugar intakes, while adjusting for major risk factors. We did not find evidence of an association between consumption of sugary foods and beverages and risk, although there was a suggestion of increased risk associated with sugary drink intake (servings per 1,000 kcal; OR=1.63, 95% CI: 0.94-2.83). Overall, we found little indication that sugar intake played a major role on ovarian cancer development.

    Hazard Analysis by Critical Control Points (HACCP) is a systematic approach to the identification, assessment, and control of hazards in the food chain. Effective HACCP requires the consideration of all chemical microbiological, and physical hazards. However, current procedures focus primarily on microbiological and physical hazards, while chemical aspects of HACCP have received relatively little attention. In this article we discuss the application of HACCP to organic chemical contaminants and the problems that are likely to be encountered in agriculture. We also present generic templates for the development of organic chemical contaminant HACCP procedures for selected raw food commodities, that is, cereal crops,raw meats, and milk.

    The regulation of food intake in fish is a complex process carried out through several different mechanisms in the central nervous system (CNS) with hypothalamus being the main regulatory center. As in mammals, a complex hypothalamic circuit including two populations of neurons: one co-expressing neuropeptide Y (NPY) and Agouti-related peptide (AgRP) and the second one population co-expressing pro-opiomelanocortin (POMC) and cocaine- and amphetamine-regulated transcript (CART) is involved in the integration of information relating to food intake control. The production and release of these peptides control food intake, and the production results from the integration of information of different nature such as levels of nutrients and hormones as well as circadian signals. The present review summarizes the knowledge and recent findings about the presence and functioning of these mechanisms in fish and their differences vs. the known mammalian model. PMID:28694769

    Contamination of cereal commodities by moulds and mycotoxins results in dry matter, quality, and nutritional losses and represents a significant hazard to the food chain. Most grain is harvested, dried and then stored on farm or in silos for medium/long term storage. Cereal quality is influenced by a range of interacting abiotic and biotic factors. In the so-called stored grain ecosystem, factors include grain and contaminant mould respiration, insect pests, rodents and the key environmental factors of temperature, water availability and intergranular gas composition, and preservatives which are added to conserve moist grain for animal feed. Thus knowledge of the key critical control points during harvesting, drying and storage stages in the cereal production chain are essential in developing effective prevention strategies post-harvest. Studies show that very small amounts of dry matter loss due to mould activity can be tolerated. With mycotoxin contamination and downgrading of lots can occur. The key mycotoxigenic moulds in partially dried grain are Penicillium verrucosum (ochratoxin) in damp cool climates of Northern Europe, and Aspergillus flavus (aflatoxins), A. ochraceus (ochratoxin) and some Fusarium species (fumonisins, trichothecenes) on temperate and tropical cereals. Studies on the ecology of these species has resulted in modelling of germination, growth and mycotoxin minima and prediction of fungal contamination levels which may lead to mycotoxin contamination above the tolerable legislative limits (e.g. for ochratoxin). The effect of modified atmospheres and fumigation with sulphur dioxide and ammonia have been attempted to try and control mould spoilage in storage. Elevated CO2 of >75% are required to ensure that growth of mycotoxigenic moulds does not occur in partially dried grain. Sometimes, preservatives based on aliphatic acids have been used to prevent spoilage and mycotoxin contamination of stored commodities, especially feed. These are

The activities, undertaken between 2008 and 2010, are related to an audit programme planning, implemented with 2 official controls for each plant, in 48 premises recognized under the Regulation (CE 854/2004, among those, 34 processing plants (cutting and processing of food of animal origin and 14 abattoirs. Data included in audit reports have been analyzed with Excel software, classifying detected non compliances (n.c. in 8 categories linked to specific food safety risk factors (structure, operative hygiene, personnel hygiene, pest control, temperature control, management of by-products, traceability, HACCP/records. By the time of the audit 83% of the inspected premises showed structural n.c.; structural aspects are the most critical point (121 n.c. out of 264, followed by operative hygiene (25% of total n.c. and pest control (13.6%. By the time of the second audit series, however, occurred a significant reduction of n.c. in both processing plants and abattoirs, falling from 264 to152, with a reduction of n.c. detection of more than 40%. The best response capacity among operators is related to pest control and HACCP plan/records. The audit procedure implemented, a part from providing a comprehensive and objective evaluation method of the food safety management system put in place by the operators, allowed, if compared to former procedures, a more objective and comprehensive evaluation of the n.c. trend and therefore of the food safety risk factors, estimating the efficacy of the control activity.

    Full Text Available Irrespective of the existence of potentially pathogenic organisms carried by animals, foods of animal origin remain the prime nutrition of humans world-wide. As such, food safety continues to be a global concern primarily to safeguard public health and to promote international trade. Application of integrated risk-based quality assurance procedures on-farm and at slaughterhouses plays a crucial role in controlling hazards associated with foods of animal origin. In the present paper we examine safety assurance systems and associated value chains for foods of animal origin based on historical audit results of some Southern African countries with thriving export trade in animal products, mainly to identify areas for improvement. Among the key deficiencies identified were: i failure to keep pace with scientific advances related to the ever-changing food supply chain; ii lack of effective national and regional intervention strategies to curtail pathogen transmission and evolution, notably the zoonotic Shiga toxin-producing Escherichia coli; and iii a lack of effective methods to reduce contamination of foods of wildlife origin. The introduction of foods of wildlife origin for domestic consumption and export markets seriously compounds already existing conflicts in legislation governing food supply and safety. This analysis identifies gaps required to improve the safety of foods of wildlife origin.

    The importance of monitoring dietary intake within a randomized controlled trial becomes vital to justification of the study outcomes when the study is food-based. A systematic literature review was conducted to determine how dietary assessment methods used to monitor dietary intake are reported and whether assisted technologies are used in conducting such assessments. OVID and ScienceDirect databases 2000-2010 were searched for food-based, parallel, randomized controlled trials conducted with humans using the search terms "clinical trial," "diet$ intervention" AND "diet$ assessment," "diet$ method$," "intake," "diet history," "food record," "food frequency questionnaire," "FFQ," "food diary," "24-hour recall." A total of 1364 abstracts were reviewed and 243 studies identified. The size of the study and country of origin appear to be the two most common predictors of reporting both the dietary assessment method and details of the form of assessment. The journal in which the study is published has no impact. Information technology use may increase in the future allowing other methods and forms of dietary assessment to be used efficiently.

    Food borne diseases, in particular gastro-intestinal infections, represent a very large group of pathologies with a strong negative impact on the health of the population because of their widespread nature. Little consideration is given to such conditions due to the fact that their symptoms are often moderate and self-limiting. This has led to a general underestimation of their importance, and consequently to incorrect practices during the preparation and preservation of food, resulting in the frequent occurrence of outbreaks involving groups of varying numbers of consumers. Despite substantial efforts in the avoidance of contamination, an upward trend in the number of outbreaks of food borne illnesses caused by non-spore forming pathogenic bacteria are reported in many countries. Good hygienic practices can reduce the level of contamination but the most important pathogens cannot presently be eliminated from most farms, nor is it possible to eliminate them by primary processing, particularly from those foods which are sold raw. Several decontamination methods exist but the most versatile treatment among them is the ionizing radiation procedure. HACCP (Hazard Analysis and Critical Control Point) is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. For successful implementation of a HACCP plan, management must be strongly committed to the HACCP concept. A firm commitment to HACCP by top management provides company employees with a sense of the importance of producing safe food. At the same time, it has to be always emphasized that, like other intervention strategies, irradiation must be applied as part of a total sanitation program. The benefits of irradiation should never be considered as an excuse for poor quality or for poor handling and storage conditions

    At the beginning of the First World War the most typical diseases in the Russian Army were typhoid, typhus, diphtheria, cholera, smallpox and other infectious diseases. At the beginning of the First World War the level of infectious morbidity was significantly low, but further increased and pandemic risk arose. Servicemen were mostly ill with typhus, relapsing fever, flux, cholera, smallpox and typhoid. The highest mortality rate was registered in patients with cholera, typhus and typhoid. According the prewar deployment program of the Russian Army anti-epidemiologic facilities were established. By the end of war were established 110 sanitary-and-hygienic and 90 disinfection units. However, organization of anti-epidemiologic security was unsatisfactory. Due to lack of specialists and equipment anti-epidemiologic facilities of units were under strength. Commanders of sanitary units and sanitary service had not enough resources for operational service in the Forces and facilities of rear area.

    To develop regulations efficiently, federal agencies need to know the costs of implementing various regulatory alternatives. As the regulatory agency responsible for the safety of meat and poultry products, the U.S. Dept. of Agriculture's Food Safety and Inspection Service is interested in the costs borne by meat and poultry establishments. This study estimated the costs of developing, validating, and reassessing hazard analysis and critical control points (HACCP), sanitary standard operating procedures (SSOP), and sampling plans; food safety training for new employees; antimicrobial equipment and solutions; sanitizing equipment; third-party audits; and microbial tests. Using results from an in-person expert consultation, web searches, and contacts with vendors, we estimated capital equipment, labor, materials, and other costs associated with these investments. Results are presented by establishment size (small and large) and species (beef, pork, chicken, and turkey), when applicable. For example, the cost of developing food safety plans, such as HACCP, SSOP, and sampling plans, can range from approximately $6000 to $87000, depending on the type of plan and establishment size. Food safety training costs from approximately $120 to $2500 per employee, depending on the course and type of employee. The costs of third-party audits range from approximately $13000 to $24000 per audit, and establishments are often subject to multiple audits per year. Knowing the cost of these investments will allow researchers and regulators to better assess the effects of food safety regulations and evaluate cost-effective alternatives. © 2017 Institute of Food Technologists®.

  1. Slicing Cuts on Food Materials Using Robotic-Controlled Razor Blade

    2011-01-01

    Full Text Available Cutting operations using blades can arise in a number of industries, for example, food processing industry, in which cheese, fruit and vegetable, even meat, are involved. Certain questions will rise during these works, such as “why pressing-and-slicing cuts use less force than pressing-only cuts” and “how is the influence of the blade cutting-edge on force”. To answer these questions, this research developed a mathematical expression of the cutting stress tensor. Based on the analysis of the stress tensor on the contact surface, the influence of the blade edge-shape and slicing angle on the resultant cutting force were formulated and discussed. These formulations were further verified using experimental results by robotic cutting of potatoes. Through studying the change of the cutting force, the optimal slicing angle can be obtained in terms of maximum feeding distance and minimum cutting force. Based on the blade sharpness properties and the specific materials, the required cutting force can be predicted. These formulation and experimental results explained the basic theory of blade cutting fracture and further provided the support to optimize the cutting mechanism design and to develop the force control algorithms for the automation of blade cutting operations.

    In the last decades, food science has greatly developed, turning from the consideration of food as mere source of energy to a growing awareness on its importance for health and particularly in reducing the risk of diseases. Such vision led to an increasing attention towards the origin and quality of raw materials as well as their derived food products. The continuous advance in molecular biology allowed setting up efficient and universal omics tools to unequivocally identify the origin of food items and their traceability. In this review, we considered the application of a genomics approach known as DNA barcoding in characterizing the composition of foodstuffs and its traceability along the food supply chain. Moreover, metabolomics analytical strategies based on Nuclear Magnetic Resonance (NMR) and Mass Spectroscopy (MS) were discussed as they also work well in evaluating food quality. The combination of both approaches allows us to define a sort of molecular labelling of food that is easily understandable by the operators involved in the food sector: producers, distributors, and consumers. Current technologies based on digital information systems such as web platforms and smartphone apps can facilitate the adoption of such molecular labelling.

    Bringing Russian legislation into compliance with international norms and standards is necessary after its accession to the World Trade Organization. Harmonization of food legislation and of sanitary and phytosanitary measures are among the problems that had to be solved first. Many Russian food and trade regulations had been changed or are still in the process of being reformed, largely owing to a policy of integration pursued by the Customs Union of Russia, Belarus and Kazakhstan. However, as a member of the Eurasian Economic Community, Russia is also engaged not only in harmonization throughout the Customs Union but also Kirgizstan and Tajikistan, and Armenia, Moldova and Ukraine as observer countries. Russia also continues to coordinate policy reforms closely with the European Union, its primary trade partner, ultimately bringing Russian food and sanitary norms closer to international standards (e.g. Codex). Today, all participants in the Russian food production chain, processing and sale of foods have to deal with growing numbers of security standards. Many organizations are certified under several schemes, which leads to unnecessary costs. Harmonization of standards has helped promote solutions in the domestic market as well as import-export of foods and raw materials for production. Priorities have included food safety for human health, consumer protection, removal of hazardous and/or adulterated products and increased competition within the domestic food market as well as mutual recognition of certification in bilateral and multilateral (inter)national agreements. © 2013 Society of Chemical Industry.

    Background: The aetiology of multiple sclerosis (MS is unclear, but numerous studies suggest that different exogenous factors can lead to the development of the disease in genetically susceptible individuals. The objective of this case-control study was to determine the role of food and dietary patterns in patients with MS in the population of Belgrade (Serbia.

    Methods: In this matched case-control study, we included 110 cases with definite MS according to McDonald’s criteria, in whom the onset symptoms occurred up to 2 years prior to the interview, who were followed-up at the Institute of Neurology, Clinical Centre of Serbia, Belgrade. The identical number of controls from the same institution, individually matched by sex, age and area of residence, was recruited from patients with various non-autoimmune neurological disorders. Dietary information was obtained by using a frequency history approach.

    Results: According to univariate conditional logistic regression analysis the following factors were significantly related to MS: body mass index (BMI less than 25 (OR=2.2, p=0.009, frequent consumption of beef (OR=1.7, p=0.043, chicken (OR=2.0, p=0.045, meat of the lamb (OR=2.1, p=0.013, butter (OR=1.7, p=0.056 and ice-cream (OR=1.8, p=0.031, with dose-response relationship. Consumption of majority of various fruit was more frequently reported by controls. According to multivariate conditional logistic regression analysis, BMI less than 25 (OR=2.3, p=0.008, consumption (weekly of beef (OR=2.0, p=0.017 and butter (OR=1.9, p=0.027 was significantly related to MS, while regular consumption of cherry (OR=0.4, p=0.024 had protective role.

    Conclusions: This study might assist in potential defining of the dietary factors that could contribute to the risk of developing MS.

    The present study investigated the effects of exposure to a food cue on the self-reported importance of dieting in those with low, medium, and high levels of dietary restraint. The results indicated that exposure to a food cue bolstered dieting-related goals in those who were low in dietary restraint but had no effect on the importance of dieting-related goals for those with medium or high levels of dietary restraint. The results demonstrate that exposure to temptations may differentially affect self-control processes depending on an individuals' level of dietary restraint.

    To prevent some intestinal trematodes which are highly prevalent in Korea, the effect of irradiation on fishes and metacercariae has been analyzed for control of parasites. The metacercariae of intestinal trematodes were irradiated with various doses, and the infection rates and developmental status were assayed for estimation of optimal radiation doses. In addition, to examine the differences of susceptibility to radiation among the parasites, superoxide dismutase (SOD) activities were determined, and degree of apoptosis were observed. As a result, 100 Gy irradiation was sufficient for Metagonimus yokogawai to redue their infectivity and development, and 200 Gy was for Gymnophalloides seoi. While Neodiplostomum seoulense, a kind of intestinal rematode, was proved to be highly susceptible to radiation, sparganum and Anisakis were resistant to radiation. These might result from the differences of SOD activity among parasites. The apoptosis of parasites was mainly observed after 100 Gy irradiation, and further study was required to decide whether these phenomenon influences the susceptibility to radiation. 21 refs., 7 figs., 4 tabs.

    2012-08-01

    In the present paper, we develop a simple two species prey-predator model in which the predator is partially coupled with alternative prey. The aim is to study the consequences of providing additional food to the predator as well as the effects of harvesting efforts applied to both the species. It is observed that the provision of alternative food to predator is not always beneficial to the system. A complete picture of the long run dynamics of the system is discussed based on the effort pair as control parameters. Optimal augmentations of prey and predator biomass at final time have been investigated by optimal control theory. Also the short and large time effects of the application of optimal control have been discussed. Finally, some numerical illustrations are given to verify our analytical results with the help of different sets of parameters.

    Traditionally, consumer food safety survey responses have been classified as either "right" or "wrong" and food handling practices that are associated with high risk of infection have been treated in the same way as practices with lower risks. In this study, a risk-based method for consumer food safety surveys has been developed, and HACCP (hazard analysis and critical control point) methodology was used for selecting relevant questions. We conducted a nationally representative Web-based survey (n = 2,008), and to fit the self-reported answers we adjusted a risk-based grading system originally developed for observational studies. The results of the survey were analyzed both with the traditional "right" and "wrong" classification and with the risk-based grading system. The results using the two methods were very different. Only 5 of the 10 most frequent food handling violations were among the 10 practices associated with the highest risk. These 10 practices dealt with different aspects of heat treatment (lacking or insufficient), whereas the majority of the most frequent violations involved storing food at room temperature for too long. Use of the risk-based grading system for survey responses gave a more realistic picture of risks associated with domestic food handling practices. The method highlighted important violations and minor errors, which are performed by most people and are not associated with significant risk. Surveys built on a HACCP-based approach with risk-based grading will contribute to a better understanding of domestic food handling practices and will be of great value for targeted information and educational activities.

    The spray dryer, which will satisfy the future demands, is developed through the engineering approach in accordance to 3A- Sanitary Standards in the food industry. The main points are as follows. 1) A High Discharge-Single Swirl Atomizer is adapted for practical use; which can mix effectively with single hot air jet. 2) An optimum jet distributer eliminates swirling components in the jet. 3) Secondary air from the periphery of the jet controls the diffusion and Coanda effect of the jet. 4) The drying chamber's wall is controlled at a temperature below the "Sticky Point" of products. 5) An optimum cooler is included in the bottom of the drying chamber. The above devices prevent undried particles from adhering to the drying chamber's wall, improve the fluidity of products as powder particles, and bring about high efficiency, stable and high quality long lasting productivity.

    On 13 November 2009, the authorities of Flemish Brabant, Belgium, received an alert concerning a potential outbreak of Shigella sonnei at a public institution. A study was conducted to assess the extent, discover the source and to implement further measures. We performed a matched case-control study to test an association between shigellosis and canteen-food consumption. Water samples and food handlers' faecal samples were tested. The reference laboratory characterized the retrospectively collected Shigella specimens. We found 52 cases distributed over space (25/35 departments) and time (2 months). We found a matched odds ratio of 3·84 (95% confidence interval 1·02-14·44) for canteen-food consumption. A food handler had travelled to Morocco shortly before detection of the first laboratory-confirmed case. Water samples and food handlers' faecal samples tested negative for Shigella. Confirmed cases presented PFGE profiles, highly similar to archived isolates from Morocco. Foodborne transmission associated with the canteen was strongly suspected.

    2007-10-01

    Full Text Available Background: Bacillus cereus spores distribute widely in nature and can be isolated from different kinds of foods. This bacterium can produce diarrhea and emetic enterotoxins and syndromes. As infants are known to be more susceptible to B. cereus infection due to their incomplete intestinal flora and fast growth of this bacterium during consumption, it is very important to investigate the presence of B. cereus in infant formula and possible pathogenicity of this microorganism in infants.  Methods: In this study, 60 samples of infant formula were examined for the presence of B. cereus. From a 1/10 dilution of each sample, a total amount of 1 ml was inoculated onto four phenol red agar plates containing mannitol, egg yolk emulsion and polymyxin B sulfate. The plates were incubated at 30°C for 24 hours. Confirmation tests were then performed on suspected colonies.Results: Among the 60 samples, 11 samples had more than 10 cfu/g, four of which contained more than 102 cfu/g. The other 49 samples showed less than 10 cfu/g of B. cereus.  Conclusions: We suggest that for infant formula the maximum microbial limit be reduced to less than 10 cfu/g to control B. cereus contamination and to prevent infection in infants. For this purpose, infant formula should be tested by the method and confirmation tests used in this study. In addition, susceptibility to penicillin, ß-hemolysis and growth rate at 45ºC could also be performed.

  4. Distributions of key exposure factors controlling the uptake of xenobiotic chemicals in an estuarine food web

    1996-11-01

    A critical evaluation of literature on the behavior, physiology, and ecology of common estuarine organisms was conducted in an attempt to develop probabilistic distributions for those variables that influence the uptake of xenobiotic chemicals from sediments, water, and food sources. The ranges, central tendencies, and distributions of several key parameter values were identified for dominant organisms from various trophic levels, including the polychaete Nereis virens, mummichog (Fundulus heteroclitus), blue crab (Callinectes sapidus), and striped bass (Morone saxatilis). The exposure factors of interest included ingestion rate for various food sources, growth rate, respiration rate, excretion rate, body weight, wet/dry weight ratio, lipid content, chemical assimilation efficiency, and food assimilation efficiency. These exposure factors are critical to the execution of mechanistic food web models, which, when properly calibrated, can be used to estimate tissue concentrations of nonionic chemicals in aquatic organisms based on knowledge of the bioenergetics and feeding interactions within a food web and the sediment and water concentrations of chemicals. In this article the authors describe the use of distributions for various exposure factors in the context of a mechanistic bioaccumulation model that is amenable to probabilistic analyses for multiple organisms within a food web. A case study is provided which compares the estimated versus measured concentrations of five polychlorinated biphenyl (PCB) congeners in a representative food web from the tidal portion of the Passaic River, New Jersey, USA. The results suggest that the model is accurate within an order of magnitude or less in estimating the bioaccumulation of PCBs in this food web without calibration. The results of a model sensitivity analysis suggest that the input parameters which most influence the output of the model are both chemical and organism specific.

    Obesity causes a significant negative impact on health of human beings world-wide. The main reason for weight gain, which eventually leads to obesity, is excessive ingestion of energy above the body's homeostatic needs. Therefore, the elucidation of detailed mechanisms for appetite control is necessary to prevent and treat obesity. N-methyl-d-aspartate (NMDA) receptor is a post-synaptic glutamate receptor and is important for excitatory neurotransmission. It is expressed throughout the nervous system, and is important for long-term potentiation. It requires both ligand (glutamate) and co-agonist (d-serine or glycine) for efficient opening of the channel to allow calcium influx. d-serine is contained in fermented foods and marine invertebrates, and brain d-serine level is maintained by synthesis in vivo and supply from food and gut microbiota. Although the NMDA receptor has been reported to take part in the central regulation of appetite, the role of d-serine had not been addressed. We recently reported that exogenous d-serine administration can suppress appetite and alter food preference. In this review, we will discuss how NMDA receptor and its co-agonist d-seine participate in the control of appetite and food preference, and elaborate on how this system could possibly be manipulated to suppress obesity.

  9. Design of self-cleansing sanitary sewer systems with the use of flushing devices.

    2009-01-01

    Many European countries tend to shift from constructing combined sewer systems to separate ones, in order to optimise wastewater treatment efficiency and reduce CSO impact on surface waters. An economic design minimises maintenance requirements by aiming at self-cleansing pipes. However, providing the necessary slopes for self-cleansing sanitary sewer pipes often is unfeasible in flat regions, resulting in an increased risk of loss of hydraulic capacity or blocking. To reduce these risks, flushing tanks can be installed in the sewer system. Where most other researchers contribute to a better understanding of the hydraulics of flushing, this paper rather tries to formulate a methodology to design and test flushing devices in sanitary sewer systems using standards and hydrodynamic simulations. Therefore, several aspects that require consideration when incorporating flushing devices into a sanitary sewer system are discussed. For instance, when flushing sanitary sewers the increase in discharge has to be explicitly considered. A Belgian case study is used to investigate the suitability of the developed methodology. Although the pipe slopes in the methodology are derived assuming uniform flow, the simulation results comply with it. Furthermore, pressurisation of the conduits due to multiple flushing waves remains within acceptable limits.

    Full Text Available Qualitative study whose objective is to know battered women perception regarding sanitary professional’s attention on gender violence in Madrid Community. The results were validated by a triangulation process. Women identified sanitary assistance with those given when there exist physical injuries. However, if we keep questioning about it, they do express to look for something else from the professionals who attended them, although they are not able to say it before them.Somatizations that ill-treatment produces are treated by sanitary professionals without attending to the cause that caused them, and, when it is identified ill-treatment as the cause, rarely sanitary professionals send them to psychologies or psychiatrics. However, this is not identified as a bad practice, because women establish a very defined and rigid function for each professional, where, as they understand, Primary Care doctor will not be required to worry about psychic health and wellbeing of people who attend to their offices.We think, therefore, that it would be recommended that Madrid Community should create a specific health program to attend these women in order to guarantee, this way, a proper attention to people who may be in this situation as well as a minimum quality on the attention they received.

    Information about the quality of rural drinking water sources can be used to manage their safety and mitigate risks to health. Sanitary surveys, which are observational checklists to assess hazards present at water sources, are simpler to conduct than microbial tests. We assessed whether sanitary survey results were associated with measured indicator bacteria levels in rural drinking water sources in Kisii Central, Kenya. Overall, thermotolerant coliform (TTC) levels were high: all of the samples from the 20 tested dug wells, almost all (95%) of the samples from the 25 tested springs, and 61% of the samples from the 16 tested rainwater harvesting systems were contaminated with TTC. There were no significant associations between TTC levels and overall sanitary survey scores or their individual components. Contamination by TTC was associated with source type (dug wells and springs were more contaminated than rainwater systems). While sanitary surveys cannot be substituted for microbial water quality results in this context, they could be used to identify potential hazards and contribute to a comprehensive risk management approach.

    There is growing evidence that requirements for particular AA increase when pigs are kept under low sanitary conditions. The extent to which reduction in growth performance is related to these increased requirements is unclear. To evaluate this relationship, an experiment (2 × 2 × 2 factorial arrangement) was performed with 612 male pigs (9 per pen) kept under low sanitary conditions (LSC) or high sanitary conditions (HSC) and offered ad libitum access to either a normal CP concentration diet (NP; 17, 15, and 15% CP for the starter, grower, and finisher phase, respectively) or a low CP concentration diet (LP; 20% CP reduced relative to NP for each phase), each of which containing a basal AA profile (AA-B) or a supplemented AA profile (AA-S). The supplemented diet type contained 20% more Met, Thr, and Trp relative to Lys on an apparent ileal digestible basis compared with the basal diet type. Pigs were followed for a complete fattening period and slaughtered at a targeted pen weight of 110 kg. Haptoglobin concentrations in serum (0.92 g/L for LSC and 0.78 g/L for HSC) and IgG antibody titers against keyhole limpet hemocyanin (3.53 for LSC and 3.08 for HSC) collected in the starter, grower, and finisher phases and pleuritis scores at slaughter (0.51 for LSC and 0.20 for HSC) were greater for LSC pigs compared with HSC pigs ( ≤ 0.01), illustrating that sanitary conditions affected health conditions. The ADG and G:F were greater for HSC pigs compared with LSC pigs ( ≤ 0.01). The number of white blood cells (WBC) was higher in (AA-S)-fed pigs compared with (AA-B)-fed pigs when kept at LSC but not at HSC [SS (sanitary conditions) × AA interaction, = 0.04]. Pigs fed NP had a lower number of WBC compared with pigs fed LP ( = 0.02). The number of platelets in pigs fed AA-S diets was higher compared with pigs fed AA-B diets ( ≤ 0.01). A 20% reduction in dietary supplementation of Met, Thr, and Trp relative to Lys decreased G:F more in LSC pigs than in HSC pigs

    Metabolomics is a science of interest in food analysis to describe and predict properties of food products and processes. It includes the development of analytical methods with the ultimate goal being the identification of so-called 'quality markers', (i.e. sets of metabolites that correlate with, for example, quality, safety, taste, or fragrance of foodstuffs). In turn, these metabolites are influenced by factors as genetic differences of the raw food ingredients (such as animal breed or crop species differences), growth conditions (such as climate, irrigation strategy, or feeding) or production conditions (such as temperature, acidity, or pressure). In cases where the routine-based measurement of a food property faces some limitations such as the lack of knowledge regarding the target compounds to monitor, monitoring based on a limited set of crucial biomarkers is a good alternative, which is of great interest for food safety purposes regarding growth promoting practices. Such an approach may be more efficient than using a classic approach based on a limited set of known metabolites of anabolic compounds. In this context, screening strategies allowing detection of the physiological response resulting from anabolic compound administration are promising approaches to detect their misuse. The global metabolomics workflow implemented for such studies is presented and illustrated through various examples of biological matrices profiling (tissue, blood, urine) and for different classes of anabolic compounds (steroids, β-agonists and somatotropin).

Contamina los alimentos afectando la salud humana, al ingerir el microorganismo y/o sus toxinas, la emética o las enterotoxinas. En Colombia son escasos los reportes de intoxicación por B. cereus y se estima que hay un gran subregistro. Por lo anterior, se recomienda aumentar la vigilancia de este patógeno y realizar estudios sobre aspectos relevantes que permitan aplicar medidas de control para disminuir las intoxicaciones por B. cereus. El objetivo de esta revisión bibliográfica es presentar información actualizada sobre B. cereus, que incluye aspectos de su biología, taxonomía, toxinas, alimentos que contamina y metodologías para detectar, prevenir y controlar este microorganismo. La información presentada es de utilidad para el público en general, especialmente personas vinculadas al sector de alimentos, inocuidad alimentaria y control de procesos. / Abstract Bacillus cereus is a genetically diverse bacterium commonly found in the environment. It contaminates food, thus affecting human health upon ingestion of the microorganism and/or its toxins, the emetic or enterotoxins. In Colombia, reports of intoxication by B. cereus are scarce and under-registration is presumed. Because of this, it is recommended to increase surveillance of this pathogen and to develop studies on relevant aspects that allow the application of control measures to reduce intoxications by B. cereus. The aim of this review is to present current information on B. cereus, including aspects of its biology, taxonomy, toxins, food that it contaminates and methodologies for the detection, prevention and control of this microorganism. This information is useful for the general public, especially people involved with the food sector, food safety and process control.
