Full Text Available Background: Staphylococcus aureus is the most prevalent infectious agent of food materials. Enterotoxin producing types of S. aureus cause well-known food-borne disease. Staphylococcal Enterotoxin A (SEA is the most important agent of gastroenteritis. Objectives: The present study aimed to screen the raw meat samples collected from different regions of Tehran for S. aureus infection and type of encoding enterotoxin. Materials and Methods: Hundred and eighty six meat samples were collected randomly from city dealers and transferred to laboratory within screw cap containers. The samples were first cultured according to the standard bacteriological methods and then S. aureus isolates were identified using standard bacteriological tests. The isolates were subjected to Polymerase Chain Reaction (PCR to detect gene encoding SEA. Results: Staphylococcus aureus isolated from 29 (15.6% meat samples including beef 14.8%, raw lamb 15%, raw chicken 15.7% and raw turkey 16.6%. Using special primer sets proved that the species isolated from five samples (two raw chicken, two raw beef and one raw turkey encoded enterotoxin A. Conclusions: Although staphylococcal contamination within food material is more or less a routine, but detection of enterotoxin encoding species from raw meat samples is alarming for health authorities. These data highlight the importance of periodic surveillance of raw meat distributed among ordinary consumers.

The present study compared the accuracy of an OFFGEL electrophoresis and tandem mass spectrometry-based proteomic approach with a DNA-based method for meat species identification from raw and cooked ground meat mixes containing cattle, water buffalo and sheep meat. The proteomic approach involved the separation of myofibrillar proteins using OFFGEL electrophoresis, SDS-PAGE and protein identification by MALDI-TOF MS. Species-specific peptides derived from myosin light chain-1 and 2 were identified for authenticating buffalo meat spiked at a minimum 0.5% level in sheep meat with high confidence. Relative quantification of buffalo meat mixed with sheep meat was done by quantitative label-free mass spectrometry using UPLC-QTOF and PLGS search engine to substantiate the confidence level of the data. In the DNA-based method, PCR amplification of mitochondrial D loop gene using species specific primers found 226bp and 126bp product amplicons for buffalo and cattle meat, respectively. The method was efficient in detecting a minimum of 0.5% and 1.0% when buffalo meat was spiked with cattle meat in raw and cooked meat mixes. Copyright © 2017 Elsevier Ltd. All rights reserved.

The aim of the study was to elaborate a method of modelling and forecasting rheological features which could be applied to raw minced meat at the stage of mixture preparation with a given ingredient composition. The investigated material contained pork and beef meat, pork fat, fat substitutes, ice and curing mixture in various proportions. Seven texture parameters were measured for each sample of raw minced meat. The data obtained were processed using the artificial neural network module in Statistica 9.0 software. The model that reached the lowest training error was a multi-layer perceptron MLP with three neural layers and architecture 7:7-11-7:7. Correlation coefficients between the experimental and calculated values in training, verification and testing subsets were similar and rather high (around 0.65) which indicated good network performance. High percentage of the total variance explained in PCA analysis (73.5%) indicated that the percentage composition of raw minced meat can be successfully used in the prediction of its rheological features. Statistical analysis of the results revealed, that artificial neural network model is able to predict rheological parameters and thus a complete texture profile of raw minced meat.

Nutritional evaluation of lowering consumption of meat and meat products in the Nordic context

DEFF Research Database (Denmark)

Tetens, Inge; Hoppe, Camilla; Frost Andersen, Lene

The World Cancer Research Fund (WCRF) recommended in 2007 that consumer intake of red meat is minimized and processed meat eliminated. The recommendation was based on a systematic review of the available literature on the association between meat consumption and cancer. The recommendation...... to individuals was to ingest less than 500 grams of red meat per weeks, and very little - if anything - processed meats. In a new study, National Food Institute has assessed the nutritional consequences from living the recommendations of the WCRF, in Norway, Sweden, Finland and Denmark. The current consumption...... of meat in the Nordic countries is not far from the level WCRF has proposed on an individual level. The study also shows that it will have no significant nutritional consequences to reduce the intake of meat to the recommended, neither when it comes to red meat nor processed meat....

Meat Consumption as a Risk Factor for Type 2 Diabetes

Directory of Open Access Journals (Sweden)

Neal Barnard

2014-02-01

Full Text Available Disease risk factors identified in epidemiological studies serve as important public health tools, helping clinicians identify individuals who may benefit from more aggressive screening or risk-modification procedures, allowing policymakers to prioritize intervention programs, and encouraging at-risk individuals to modify behavior and improve their health. These factors have been based primarily on evidence from cross-sectional and prospective studies, as most do not lend themselves to randomized trials. While some risk factors are not modifiable, eating habits are subject to change through both individual action and broader policy initiatives. Meat consumption has been frequently investigated as a variable associated with diabetes risk, but it has not yet been described as a diabetes risk factor. In this article, we evaluate the evidence supporting the use of meat consumption as a clinically useful risk factor for type 2 diabetes, based on studies evaluating the risks associated with meat consumption as a categorical dietary characteristic (i.e., meat consumption versus no meat consumption, as a scalar variable (i.e., gradations of meat consumption, or as part of a broader dietary pattern.

Raw milk consumption and health

Full Text Available Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has strengthened significantly in recent years. Traditional agricultural manufacturers from Serbia still sell products related to thermally unprocessed milk, such as cottage cheese and raw cream. In AP Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks were reported, where the incriminated cause of the outbreak were milk or diary. In 126 (70.39% outbreaks, totaling 2276 sick individuals and one casualty, it was confirmed that the incriminated food was from the group of dairy products. In 48 instances (26.82%, bacteriological tests confirmed that milk and dairy products were excluded as the outbreak causes, while in another 5 (2.79% outbreaks, microbiological analysis of food failed to confirm any relation to the actual epidemiological instances. In some cases, bacteriological testing of incriminated foods was not possible. In the cases of outbreaks associated with the consumption of milk and dairy products, traditional raw milk products were cited as being used. Consumption of unpasteurized milk and cheese represents public health threat. National and international rules ensuring use of safe products for human consumption have to set rules of trade of thermally processed milk and products on the market.

The significance of sensory appeal for reduced meat consumption.

Tucker, Corrina A

2014-10-01

Reducing meat (over-)consumption as a way to help address environmental deterioration will require a range of strategies, and any such strategies will benefit from understanding how individuals might respond to various meat consumption practices. To investigate how New Zealanders perceive such a range of practices, in this instance in vitro meat, eating nose-to-tail, entomophagy and reducing meat consumption, focus groups involving a total of 69 participants were held around the country. While it is the damaging environmental implications of intensive farming practices and the projected continuation of increasing global consumer demand for meat products that has propelled this research, when asked to consider variations on the conventional meat-centric diet common to many New Zealanders, it was the sensory appeal of the areas considered that was deemed most problematic. While an ecological rationale for considering these 'meat' alternatives was recognised and considered important by most, transforming this value into action looks far less promising given the recurrent sensory objections to consuming different protein-based foods or of reducing meat consumption. This article considers the responses of focus group participants in relation to each of the dietary practices outlined, and offers suggestions on ways to encourage a more environmentally viable diet.

On 5 June 2012 several enterohemorrhagic Escherichia coli, EHEC, O157:H7 infections were reported to the public health authorities of Limburg. We performed a case-control study, a trace back/forward investigation and compared strains isolated from human cases and food samples. A case was defined as anyone with a laboratory-confirmed E. coli O157:H7-infection in North-East Limburg from May 30 2012 till July 15 2012. Family members with bloody diarrhea were also included as cases. E. coli O157 was isolated by culture and the presence of the virulence genes was verified using (q)PCR. Isolates were genotyped and compared by Pulsed Field Gel Electrophoresis (PFGE) and insertion sequence 629-printing (IS629-printing). The outbreak involved 24 cases, of which 17 were laboratory-confirmed. Five cases developed Hemolytic Uremic Syndrome (HUS) and fifteen were hospitalized. Cases reported a significantly higher consumption of "steak tartare", a raw meat product (OR 48.12; 95% CI; 5.62- 416.01). Cases were also more likely to buy meat-products at certain butcheries (OR 11.67; 95% CI; 1.41 - 96.49). PFGE and IS629-printing demonstrated that the vtx1a vtx2a eae ehxA positive EHEC O157:H7 strains isolated from three meat products and all seventeen human stool samples were identical. In a slaughterhouse, identified by the trace-back investigation, a carcass infected with a different EHEC strain was found and confiscated. We present a well described and effectively investigated foodborne outbreak associated with meat products. Our main recommendations are the facilitation and acceleration of the outbreak detection and the development of a communication plan to reaches all persons at risk.

1997-01-01

Breast and leg meat patties, prepared from turkeys fed diets containing 25, 200, 400 or 600 IU of dl-alpha-tocopheryl acetate (TA) per kg diet, were irradiated at 0 or 2.5 kGy with vacuum or loose packaging. The effects of dietary TA on storage stability and production of volatiles in irradiated raw turkey meat were determined. Dietary TA at 200 IU/kg decreased lipid oxidation and reduced total volatiles of raw turkey patties after 7-days of storage. However, the antioxidant effects of dietary TA were more notable when the patties were loosely packaged than when vacuum-packaged. Irradiation increased lipid oxidation of raw turkey meats only when loosely packaged but had limited effects on formation of total volatiles after storage at 4 degrees C for 7 days or longer

Alternative futures for world cereal and meat consumption.

Fundamental changes in the global structure of food demand will lead to an extraordinary increase in the importance of developing countries in global food markets. Economic growth in developing countries is changing consumption patterns, with slower growth (and in many countries actual declines) in per capita food consumption of grains and rapidly growing per capita and total meat consumption, combined with induced growth in cereal feed consumption. The present paper examines the hypothesis, suggested by some researchers, that high-meat diets in developed countries limit improvement in food security in developing countries. These analysts argue that reduced meat consumption in developed countries would release cereals from livestock feed to food for poorer populations, thus improving food security in developing countries. Using the International Food Policy Research Institute (Washington, DC, USA) global food projections model, the international model for policy analysis of agricultural commodities and trade (see Rosegrant et al. 1995), we first analyse the implications for future global cereal and meat supply and demand resulting from changes in global income, population growth and other structural changes, then simulate alternative scenarios to examine the effect of large reductions in meat consumption in developed countries on food consumption and food security in developing countries. The paper shows that while the long-term prospects for food supply, demand and trade indicate a strengthening of world cereal and livestock markets, the improvement in food security in the developing world will be slow, and changes in the dietary patterns in developed countries are not an effective route to improvement in food security in developing countries.

This study was conducted to determine the effects of feeding olive cake and linseed to lambs on the volatile organic compounds (VOCs) in raw and cooked meat. Four groups of eight male Appenninica lambs each were fed: conventional cereal-based concentrates (diet C), concentrates containing 20% on a dry matter (DM) basis of rolled linseed (diet L), concentrates containing 35% DM of stoned olive cake (diet OC), or concentrates containing both rolled linseed (10% DM) and stoned olive cake (17% DM; diet OCL). The longissimus dorsi muscle of each lamb was sampled at slaughter and was subjected to VOC profiling through the use of SPME-GC-MS. In the raw meat, the concentration of 3-methylpentanoic acid was higher in treatment C as compared with treatments L, OC and OCL (Pcooked meat the amount of 1-pentanol was higher in treatment C than in treatment OC (Plamb meat.

Meat consumption: trends and quality matters.

This paper uses quality theory to identify opportunities for the meat sector that are consistent with trends in meat consumption. Meat consumption has increased and is likely to continue into the future. Growth is largely driven by white meats, with poultry in particular of increasing importance globally. The influence of factors such as income and price is likely decline over time so that other factors, such as quality, will become more important. Quality is complex and consumers' quality expectations may not align with experienced quality due to misconception of certain intrinsic cues. Establishing relevant and effective cues, based on extrinsic and credence attributes, could offer advantage on the marketplace. The use of extrinsic cues can help convey quality characteristics for eating quality, but also for more abstract attributes that reflect individual consumer concerns e.g. health/nutrition, and collective concerns, e.g. sustainability. However, attributes are not of equal value to all consumers. Thus consumer segmentation and production differentiation is needed. Copyright © 2014 Elsevier Ltd. All rights reserved.

This study aimed to estimate the consumption of meat and products derived from hunting by the consumer population and, specifically, by hunters and their relatives. For this purpose, a survey was conducted on the frequency of consuming meat from the four most representative game species in Spain, two of big game, wild boar (Sus scrofa) and red deer (Cervus elaphus) and two of small game, rabbit (Oryctolagus cunulucus) and red partridge (Alectoris rufa), as well as of processed meat products (salami-type sausage) made from those big game species. The survey was carried out on 337 habitual consumers of these types of products (hunters and their relatives). The total mean game meat consumption, per capita in this population group, is 6.87 kg/person/year of meat and 8.57 kg/person/year if the processed meat products are also considered. Consumption of rabbit, red partridge, red deer and wild boar, individually, was 1.85, 0.82, 2.28 and 1.92 kg/person/year, respectively. It was observed that hunters generally registered a larger intake of game meat, this being statistically significant in the case of rabbit meat consumption. Using probabilistic methods, the meat consumption frequency distributions for each hunting species studied were estimated, as well as the products made from big game species and the total consumption both of meat by itself and that including the products made from it. The consumption frequency distributions were adjusted to exponential ones, verified by the test suitable for it according to Akaike Information Criterion, Bayesian Information Criterion, the Chi-Squared and Kolmogorov-Smirnov statistics. In addition, the consumption percentiles of the different distributions were obtained. The latter could be a good tool when making nutrition or contaminant studies since they permit the assessment of exposure to the compound in question.

Full Text Available The objective of this study was to determine the effect of tannic acid (TA on the oxidative stability and the quality characteristics of ground chicken breast meat. Five treatments including (1 control (none added, (2 2.5 ppm TA, (3 5 ppm TA, (4 10 ppm TA, and (5 5 ppm butylated hydroxyanisole (BHA were added to boneless, skinless ground chicken breast meat, and used for both raw and cooked meat studies. For the raw meat study, the ground chicken breast meat was packaged in oxygen-permeable bags and stored at 4 °C for 7 days. For the cooked study, raw ground meat samples were vacuum-packaged in oxygen-impermeable vacuum bags, cooked in-bag to the internal temperature of 75 °C, re-packaged in oxygen-permeable bags, and then stored. Both raw and cooked meats were analyzed for lipid and protein oxidation, color, and volatiles (cooked meat only at 0, 3, and 7 days of storage. Raw meats with 10 ppm of TA added had significantly (p ≤ 0.05 lower lipid and protein oxidation than other treatments during storage. In addition, TA at 10 ppm level maintained the highest color a*- and L*-values during storage. Cooked chicken breast meat with 5 and 10 ppm TA added produced significantly (p ≤ 0.05 lower amounts of off-odor volatiles than other treatments. Among the volatile compounds, the amount of hexanal increased rapidly during storage for cooked meat. However, meats with 5 and 10 ppm TA added showed the lowest amount of hexanal and other aldehydes related to lipid oxidation, indicating a strong antioxidant effect of TA in cooked chicken breast meat. Furthermore, the differences in aldehydes among the treatments were bigger in cooked than in raw meat, indicating that the antioxidant effect of TA in cooked meat was greater than that in raw meat. Therefore, TA at >5 ppm can be used as a good natural preservative in cooked chicken meat to maintain its quality during storage.

Red meat and processed meat consumption have been associated with increased risk of colorectal cancer in some, but not all, relevant cohort studies. Evidence on the relationship between risk of colorectal cancer and poultry and fish consumption is inconsistent. We conducted a prospective cohort study of 37,112 residents of Melbourne, Australia recruited from 1990 to 1994. Diet was measured with a food frequency questionnaire. We categorized the frequency of fresh red meat, processed meat, chicken, and fish consumption into approximate quartiles. Adenocarcinomas of the colon or rectum were ascertained via the Victorian Cancer Registry. We identified 283 colon cancers and 169 rectal cancers in an average of 9 years of follow-up. For rectal cancer, the hazard ratios [95% confidence intervals (95% CI)] in the highest quartile of consumption of fresh red meat and processed meat were 2.3 (1.2-4.2; P for trend = 0.07) and 2.0 (1.1-3.4; P for trend = 0.09), respectively. The corresponding hazard ratios (95% CIs) for colon cancer were 1.1 (0.7-1.6; P for trend = 0.9) and 1.3 (0.9-1.9; P for trend = 0.06). However, for neither type of meat was the heterogeneity between subsites significant. Chicken consumption was weakly negatively associated with colorectal cancer (hazard ratio highest quartile, 0.7; 95% CI, 0.6-1.0; P for trend = 0.03), whereas hazard ratios for fish consumption were close to unity. Consumption of fresh red meat and processed meat seemed to be associated with an increased risk of rectal cancer. Consumption of chicken and fish did not increase risk.

Full Text Available A rapid immunodiagnostic test that provides visual evidence of the presence of pork components in raw beef and chicken meats was developed. Colloidal gold was prepared and conjugated with anti-Swine IgG polyclonal antibody. Immunochromatographic test strips were produced, and then were used to test laboratory adulterated raw meat samples. The samples consisted adulteration meat, immunodiagnostic, pork, rapid test of pork-in-beef, or pork-in-chicken at 1/0; 1/100; 1/1,000; 1/5,000; 1/10,000 (w/w adulteration levels that were extracted in phosphate-buffered saline. Raw beef and chicken meats without pork were included as controls. Analysis was completed in 10 min. Detection limit was 1/5,000 (w/w, although 1/10,000 was also observed. This immunodiagnostic tests can be conveniently applied to detect low levels of pork components in raw beef and chicken meat products. For the commercial purposes, further studies need to be carried out.

The properties of raw meat and meat curry from spent goat meat in relation with post-mortem handling conditions were evaluated. The conditions evaluated were: cooking of meat within 1-2 h post-slaughter (condition 1); deboning meat storage at 25 ± 2 °C for 5-6 h and cooking (condition 2); post-slaughter storage of carcass at room temperature for 5-6 h, then deboning followed by storage of meat at refrigeration temperature for 5-6 h and cooking (condition 3); deboning and storage of meat at 25 ± 2 °C for 10-12 h and cooking (condition 4). Significant difference was observed in pH values in condition 1 (p meat as compared to the conditions 2, 3 and 4. However, the moisture content of cooked meat was significantly higher (p meat chunks, that is, the mean value was significantly higher (p < 0.01) for condition 2 and significantly lower for condition 1. Sensory scores were significantly higher in condition 1 and significantly lower in condition 2. However, sensory scores for condition 4 were almost similar to the condition 1.

It has been suggested that the color of turkey breast meat influences both physico-chemical and microbiological properties of raw fermented sausages. In this study, raw fermented sausages were produced with turkey breast meat in 3 different colors (pale, normal, or dark), which were obtained from 2 fast-growing-genetic-line toms at 2 slaughterhouses. Prior to the sausage production, the breast muscles were sorted into color groups according to the lightness values determined at 24 h postmortem. This meat was subsequently processed to raw fermented sausages using 1.5 or 2.5% curing salt (CS). The pale meat had higher lightness, electrical conductivity, and drip loss, whereas the dark meat showed a darker color only. The physico-chemical (pH, water activity), visual (lightness, redness), and microbial (total plate count) properties of the sausages were not influenced by the color of the turkey breast meat. The sausage made with 2.5% CS had lower aw and higher ash and hardness values than the sausages produced with 1.5% CS. In conclusion, processing of differently colored turkey meat to raw fermented sausages does not influence the quality characteristics of the products. Based on these findings, there is no reason for the sausage producer to separate turkey breast muscles by color before producing raw fermented sausages.

Food safety hazards associated with consumption of raw milk.

An increasing number of people are consuming raw unpasteurized milk. Enhanced nutritional qualities, taste, and health benefits have all been advocated as reasons for increased interest in raw milk consumption. However, science-based data to substantiate these claims are limited. People continue to consume raw milk even though numerous epidemiological studies have shown clearly that raw milk can be contaminated by a variety of pathogens, some of which are associated with human illness and disease. Several documented milkborne disease outbreaks occurred from 2000-2008 and were traced back to consumption of raw unpasteurized milk. Numerous people were found to have infections, some were hospitalized, and a few died. In the majority of these outbreaks, the organism associated with the milkborne outbreak was isolated from the implicated product(s) or from subsequent products made at the suspected dairy or source. In contrast, fewer milkborne disease outbreaks were associated with consumption of pasteurized milk during this same time period. Twenty nine states allow the sale of raw milk by some means. Direct purchase, cow-share or leasing programs, and the sale of raw milk as pet food have been used as means for consumers to obtain raw milk. Where raw milk is offered for sale, strategies to reduce risks associated with raw milk and products made from raw milk are needed. Developing uniform regulations including microbial standards for raw milk to be sold for human consumption, labeling of raw milk, improving sanitation during milking, and enhancing and targeting educational efforts are potential approaches to this issue. Development of pre- and postharvest control measures to effectively reduce contamination is critical to the control of pathogens in raw milk. One sure way to prevent raw milk-associated foodborne illness is for consumers to refrain from drinking raw milk and from consuming dairy products manufactured using raw milk.

Meat is a good source of proteins and irons, yet its consumption has been associated with unfavorable cardiovascular effects. Whether this applies to all types of meat is unclear. We thus aimed to appraise the impact of water buffalo meat consumption on cardiovascular risk profile with an observational longitudinal study. Several important cardiovascular risk features were appraised at baseline and at 12-month follow-up in 300 adult subjects divided in groups: recent consumers of water buffalo meat vs subjects who had never consumed water buffalo meat. In addition, long-standing consumers of water buffalo meat were evaluated. Age, gender, height, body weight, and the remaining diet (with the exception of cow meat consumption) were similar across groups. From baseline to follow-up, recent consumers of water buffalo meat change their intake of water buffalo meat from none to 600+/-107 g per week (Pconsumption from 504+/-104 to 4+/-28 (PConsumption of buffalo meat seems to be associated with several beneficial effects on cardiovascular risk profile. Awaiting further randomized clinical trials, this study suggests that a larger consumption of water buffalo meat could confer significant cardiovascular benefits, while continuing to provide a substantial proportion of the recommended daily allowance of protein.

Listeria and particularly Listeria monocytogenes are important foodborne pathogens that can cause listeriosis and severe complications in immunocompromised individuals, children, pregnant women, and the elderly. The objective of this study was to determine the prevalence of Listeria spp. in raw meat in Iran. From July 2010 to November 2011, a total of 1,107 samples of various raw meats were obtained from randomly selected retail butcher shops. The results of conventional bacteriologic and PCR methods revealed that 141 samples (12.7%) were positive for Listeria spp. The highest prevalence of Listeria was found in raw buffalo meat samples (7 of 24 samples; 29.2%) followed by quail meat (26 of 116 samples; 22.4%), partridge meat (13 of 74 samples; 17.6%), and chicken meat (27 of 160 samples; 16.9%). The most common species recovered was Listeria innocua (98 of 141 strains; 75.9 % ); the remaining isolates were L. monocytogenes (19.1% of strains), Listeria welshimeri (6.4% of strains), Listeria seeligeri (3.5% of strains), and Listeria grayi (1.4% of strains). Susceptibilities of the 141 strains to 11 antimicrobial drugs were determined using the disk diffusion assay. Overall, 104 (73.8%) of the Listeria isolates were resistant to one or more antimicrobials, and 17.0% of the isolates were resistant to three or more antimicrobials. The present study provides the first baseline data on the prevalence of Listeria in raw meat derived from sheep, goat, buffalo, quail, partridge, chicken, and ostrich in Iran and the susceptibility of these isolates to antimicrobials.

Campylobacteriosis was the most commonly reported zoonosis for confirmed human cases in European Union during 2011. Poultry meat was very often implicated in Campylobacter infections in humans. In Italy commerce of raw poultry meat is common in open-air markets: these areas can be considered at high risk of bacterial contamination due to the high presence birds like pigeons. The aim of this study was to collect data about the contamination by thermotolerant Campylobacter of raw poultry meat commercialised in open-air markets, of work-surfaces in contact with poultry meat and of pigeon stools sampled in the market areas in Turin, Northern Italy. Between September 2011 and December 2012, 86 raw poultry meat samples, 86 environmental swabs and 108 animal samples were collected in 38 open-air markets. Analysis were carried out according to ISO10272-1:2006 standard. C.coli was detected in 2.3% (2/86) of raw poultry meat samples, whereas no swab (0/86) resulted positive. Of pigeon stool 28% (30/107) was positive for C.jejuni (83.3% C.jejuni subsp . jejuni and 16.7% C.jejuni subsp . doylei ). C.jejuni subsp. jejuni was isolated from 1 dead pigeon . Our results showed lower rates of contamination than those reported at retail in Europe. Although samples were collected in areas at high risk of contamination, raw poultry meat and work surfaces reported a low level of presence of thermotolerant Campylobacter . The high percentage of C.jejuni isolated from pigeon stools showed the importance of a continuous application of preventive measures by the food business operators and the surveillance activity by the Competent Authority.

Background : An adequate diet contributes to health and wellbeing in older age. This is nowadays more important than ever since in industrialised countries the elderly population is growing continually. However, information regarding the consumption behaviour of older persons in Switzerland is limited. Objective : The objective of this investigation was to explore how middle-aged and elderly Swiss view animal products in relation to diet and health, and what factors predict consumption frequency. Design : A representative consumer survey among 632 people over the age of 50 years, living in the German-, French- and Italian-speaking regions of Switzerland was conducted. Results : This paper presents the results related to meat and meat products consumption. Most participants consumed meat and meat products regularly. The majority of participants with low meat intake indicated that eating small amounts would be enough. Respondents judged fresh meat (except pork) to be healthier than meat products, and poultry to be the healthiest meat. Overall meat consumption frequency was predicted by language region, gender, household size, and BMI. Furthermore, participants' opinion about healthiness, taste and safety of meat but not their adherence to the Swiss food pyramid was found to be correlated to the consumption frequency of individual types of meat. Conclusion : Several factors have an impact on consumption frequency of meat and meat products in the middle-aged and elderly Swiss population and the importance varies according to the individual types of meat and meat products. The results show that the traditional food pyramid is not one of these factors for which reason new tools must be explored to support elderly people in regard to a healthy dietary behaviour.

Full Text Available Previous studies indicate that religion may influence consumer attitude and behavior in general, especially in food purchasing decisions and eating habits. There are limited studies that examined the role of religiosity in consumer behaviour; especially in relations to halal meat consumption. Due to gaps found in the literature, this study investigates the determinants of intention to eat halal meat. It also examines the levels of determinants of halal meat consumption between Indonesian Muslim living in Jakarta and Melbourne. Respondents were personally and electronically contacted. In total, 160 questionnaires were completed for this initial study. The results indicate that behavioural control and availability of halal meat have significant impact on intention to eat halal meat. The results further suggest that in general there are no significant differences in the levels of determinants of halal meat consumption between Indonesian Muslim living in Jakarta compared to those of in Melbourne, except for availability of halal meat. This study contributes to the marketing literature focuses on the impacts of religion on consumer behaviour which is still under researched.

The prevalence of Toxoplasma gondii, an economically important zoonotic protozoan, was investigated in horses slaughtered for export and human consumption in the North of Romania. Pairs of samples, sera and heart tissues, were collected from 82 slaughtered horses. Examination of horse sera by ELISA at a dilution of 1:10, and by modified agglutination test (MAT) at a dilution of 1:6, revealed that 32 (39%) and 31(37.8%) horses, respectively, had antibodies against T. gondii. Using polymerase chain reaction (PCR) analysis, T. gondii DNA was not found in any heart sample collected from horses. By bioassay in mice, we obtained viable isolates of T. gondii from two of ten horses determined to be strongly positive by serological assay/ELISA. The prevalence estimated in horses highlighted the potential risk for human contamination by consumption of raw or undercooked meat. Copyright © 2015 Elsevier B.V. All rights reserved.

A case-control study was conducted in Uruguay, including 876 male cases of lung cancer and 876 male hospitalized controls, frequency matched for age (ten-year intervals), residence and hospital. The following explanatory variables were included in the study: fried red meat, barbecued red meat, boiled red meat, and salted red meat. These items were log transformed and energy-adjusted by the residuals method. The following potential confounders were included into the models: age, residence, hospital, education, family history of lung cancer, body mass index, smoking index, alcohol drinking, mate consumption, total energy intake, non-meat fatty foods and total fruits. The main objective was to estimate the odds ratios associated with lung cancer risk. Whereas fried meat, barbecued meat, and salted meat were positively associated with risk (OR of the highest quartile of salted meat versus the lowest, 2.90, 95 % CI 1.99-4.25, p-value for trend<0.0001), boiled red meat was mainly protective. We conclude that salted meat was the main risk factor. The mechanisms could be related to the content of N-nitroso compounds in salted meat.

The vast amount of meat consumed in the Western world is critically discussed with regard to negative health consequences, environmental impact, and ethical concerns for animals, emphasizing the need to extend knowledge regarding the correlates of meat consumption in the general population. In the present article, we conducted two studies examining the associations between meat consumption and personality traits, political attitudes, and environmental attitudes in two large German representative samples (N total  = 8,879, aged 18-96 years). Cross-sectional data on frequency of meat consumption, socio-demographics, personality traits, and political and environmental attitudes were collected via self-reports. In both studies, male sex, younger age, and lower educational attainment were significantly positively related to meat consumption. In Study 1, results of the partial correlations and the hierarchical regression analysis controlling for socio-demographics showed that the personality traits of openness and agreeableness, as well as conservative political and social views, explained unique variance in meat consumption. In Study 2, partial correlations and hierarchical regression analyses showed that openness, agreeableness, and conscientiousness were all uniquely negatively related to meat consumption. Moreover, these analyses documented that people scoring high in right-wing attitudes and low in pro-environmental attitudes reported more overall meat consumption. Taken together, these two studies provided evidence that socio-demographics, personality traits, and attitudes are indeed related to how much meat is consumed. Implications and future prospects for the study of individual differences in meat consumption are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Impact of meat consumption, preparation, and mutagens on aggressive prostate cancer.

Directory of Open Access Journals (Sweden)

Sanoj Punnen

Full Text Available The association between meat consumption and prostate cancer remains unclear, perhaps reflecting heterogeneity in the types of tumors studied and the method of meat preparation--which can impact the production of carcinogens.We address both issues in this case-control study focused on aggressive prostate cancer (470 cases and 512 controls, where men reported not only their meat intake but also their meat preparation and doneness level on a semi-quantitative food-frequency questionnaire. Associations between overall and grilled meat consumption, doneness level, ensuing carcinogens and aggressive prostate cancer were assessed using multivariate logistic regression.Higher consumption of any ground beef or processed meats were positively associated with aggressive prostate cancer, with ground beef showing the strongest association (OR = 2.30, 95% CI:1.39-3.81; P-trend = 0.002. This association primarily reflected intake of grilled or barbequed meat, with more well-done meat conferring a higher risk of aggressive prostate cancer. Comparing high and low consumptions of well/very well cooked ground beef to no consumption gave OR's of 2.04 (95% CI:1.41-2.96 and 1.51 (95% CI:1.06-2.14, respectively. In contrast, consumption of rare/medium cooked ground beef was not associated with aggressive prostate cancer. Looking at meat mutagens produced by cooking at high temperatures, we detected an increased risk with 2-amino-3,8-Dimethylimidazo-[4,5-f]Quinolaxine (MelQx and 2-amino-3,4,8-trimethylimidazo(4,5-fqunioxaline (DiMelQx, when comparing the highest to lowest quartiles of intake: OR = 1.69 (95% CI:1.08-2.64;P-trend = 0.02 and OR = 1.53 (95% CI:1.00-2.35; P-trend = 0.005, respectively.Higher intake of well-done grilled or barbequed red meat and ensuing carcinogens could increase the risk of aggressive prostate cancer.

A number of epidemiological studies have examined the effect of meat consumption on depression. However, no conclusion has been reached. The aim of this study was to examine the relationship between meat consumption and depression. The electronic databases of PUBMED and EMBASE were searched up to March 2017, for observational studies that examined the relationship between meat consumption and depression. The pooled odds ratio (OR) for the prevalence of depression and the relative risk (RR) for the incidence of depression, as well as their corresponding 95% confidence interval (CI), were calculated respectively (the highest versus the lowest category of meat consumption). A total of eight observational studies (three cross-sectional, three cohort and two case-control studies) were included in this meta-analysis. Specifically, six studies were related to the prevalence of depression, and the overall multi-variable adjusted OR suggested no significant association between meat consumption and the prevalence of depression (OR = 0.89, 95% CI: 0.65 to 1.22; P = 0.469). In contrast, for the three studies related to the incidence of depression, the overall multi-variable adjusted RR evidenced an association between meat consumption and a moderately higher incidence of depression (RR = 1.13, 95% CI: 1.03 to 1.24; P = 0.013). Meat consumption may be associated with a moderately higher risk of depression. However, it still warrants further studies to confirm such findings due to the limited number of prospective studies.

Compared with the abundant data from Western countries, evidence regarding meat consumption and colorectal cancer is limited in the Japanese population. We evaluated colorectal cancer risk in relation to meat consumption in a population-based prospective cohort study in Japan. Participants were 13 957 men and 16 374 women aged ≥35 years in September 1992. Meat intake, assessed with a validated food frequency questionnaire, was controlled for the total energy intake. The incidence of colorectal cancer was confirmed through regional population-based cancer registries and histological identification from colonoscopy in two main hospitals in the study area. From September 1992 to March 2008, 429 men and 343 women developed colorectal cancer. After adjustments for multiple confounders, a significantly increased relative risk of colorectal cancer was observed in the highest versus lowest quartile of the intake of total and red meat among men; the estimated hazard ratios were 1.36 (95% CI: 1.03, 1.79) for total meat (P for trend = 0.022), and 1.44 (95% CI: 1.10, 1.89) for red meat (P for trend = 0.009). A positive association between processed meat intake and colon cancer risk was also observed in men. There was no significant association between colorectal cancer and meat consumption in women. These results suggest that the intake of red and processed meat increases the risk of colorectal or colon cancer among Japanese men. Abstaining from excessive consumption of meat might be protective against developing colorectal cancer. © 2017 The Authors.

The method performance characteristics of commercially available PCR kits for animal species identification were established. Comminuted meat products containing different levels of pork were prepared from authentic beef, chicken, and turkey. These meat products were analysed in the raw state and after cooking for 20 min at 200 °C. For both raw and cooked meats, the PCR kit could correctly identify the animal species and could reliably detect the addition of pork at a level below 0.1%. A survey of 42 Turkish processed meat products such as soudjouk, salami, sausage, meatball, cured spiced beef and doner kebap was conducted. Thirty-six samples were negative for the presence of pork (meatball sample labelled as 100% beef was found to contain chicken. Another turkey meatball sample was predominantly chicken.

Impacts of reducing red meat consumption on agricultural production in Finland

Directory of Open Access Journals (Sweden)

Heikki Sakari Lehtonen

2013-10-01

Full Text Available This paper summarises the simulated effects on Finnish agricultural production and trade of a 20% decrease in Finnish demand for red meat (beef, pork, lamb. According to our results, reduced red meat consumption would be offset by increased consumption of poultry meat, eggs, dairy products and fish, as well as small increases in consumption of fruits and vegetables, peas, nuts, cereal products and sweets. By including the derived demand changes in an agricultural sector model, we show that livestock production in Finland, incentivised by national production-linked payments for milk and bovine animals, would decrease by much less than 20% due to the complex nature of agricultural production and trade. Overall, assuming unchanged consumer preferences and agricultural policy, a 20% reduction in red meat consumption is not likely to lead to a substantial decrease in livestock production or changed land use, or greenhouse gas emissions, from Finnish agriculture.

Campylobacter spp. are one of the most common causes of acute bacterial gastroenteritis in human beings which are transmitted mostly via food originating from animals. This study was conducted to determine the prevalence and antimicrobial resistance of Campylobacter spp. isolated from retail raw meats in Iran. From June 2008 to June 2009, a total of 722 raw meat samples from camel (n = 107), beef (n = 190), lamb (n = 225), and goat (n = 180) were purchased from randomly selected retail outlets in Isfahan and Yazd, Iran, and were evaluated for the presence of Campylobacter spp. In this study, 50 of the 722 meat samples (6.9%) were contaminated with Campylobacter spp. The highest prevalence of Campylobacter spp. was found in lamb meat (12.0%), followed by goat meat (9.4%), beef meat (2.4%), and camel meat (0.9%). The most prevalent Campylobacter spp. isolated from the meat samples was Campylobacter jejuni (84.0%); the remaining isolates were Campylobacter coli (16.0%). Susceptibilities of 50 Campylobacter isolates were determined for 10 antimicrobial drugs using the disk-diffusion assay. Resistance to tetracycline was the most common finding (68.0%), followed by resistance to ciprofloxacin (46.0%) and nalidixic acid (40.0%). All of the isolates were susceptible to erythromycin, gentamicin, and chloramphenicol. Significantly higher prevalence rates of Campylobacter spp. (p meat samples taken in spring (20.0%) and summer (18.9%). To our knowledge, this study is the first report of the isolation of Campylobacter spp. from raw camel, lamb, and goat meat in Iran.

Asian populations have changed from traditional to Westernized diets, with increased red meat intake. They are suggested to be particularly susceptible to the adverse effects of red meat on the development of colorectal cancers, however, few prospective studies of this putative link have been conducted. We examined associations between the consumption of red and processed meat and the risk of subsite-specific colorectal cancer by gender in a large Japanese cohort. During 1995-1998, a validated food frequency questionnaire was administered to 80,658 men and women aged 45-74 years. During 758,116 person-years of follow-up until the end of 2006, 1,145 cases of colorectal cancer were identified. Higher consumption of red meat was significantly associated with a higher risk of colon cancer among women [multivariate hazard ratios (95%CIs) for the highest versus lowest quintiles (HR): 1.48 (1.01, 2.17; trend p=0.03)], as was higher consumption of total meat among men [HR=1.44 (1.06, 1.98; trend p=0.07)]. By site, these positive associations were found for the risk of proximal colon cancer among women and for distal colon cancer among men. No association was found between the consumption of processed meat and risk of either colon or rectal cancer. In conclusion, red meat intake may modestly increase the risk of colon cancer in middle-aged Japanese, although the highest quintile of red meat consumption could be considered moderate by Western standards.

The consumption of horse-meat is currently not popular in most countries, but because of its availability and recognized nutritional value consumption is slowly increasing in several western European countries based on claims that it could be an alternative red meat. In this review, horse-meat production, trade and supply values have been summarized. In addition, the advantage of horse production is noted because of its lower methane emissions and increased uptake, particularly of n-3 polyunsaturated fatty acids (PUFAs), which is based on its digestive physiology. Of particular interest in this review is the unique fatty acid composition of horse-meat with its high level of the nutritionally desirable PUFAs in both the adipose and muscle fat. Because of its large frame size and digestive physiology, the horse can be considered an alternative to bovine meat, with large advantages regarding the maintenance of less favored mountain grazing areas and its facility to transfer PUFA from feed to meat.

In Argentina, there are three known species of genus Trichinella; however, Trichinella spiralis is most commonly associated with domestic pigs and it is recognized as the main cause of human trichinellosis by the consumption of products made with raw or insufficiently cooked pork meat. In some areas of Argentina, this disease is endemic and it is thus necessary to develop a more effective programme of prevention and control. Here, we developed a quantitative risk assessment of human trichinellosis following pork meat sausage consumption, which may be used to identify the stages with greater impact on the probability of acquiring the disease. The quantitative model was designed to describe the conditions in which the meat is produced, processed, transported, stored, sold and consumed in Argentina. The model predicted a risk of human trichinellosis of 4.88 × 10(-6) and an estimated annual number of trichinellosis cases of 109. The risk of human trichinellosis was sensitive to the number of Trichinella larvae that effectively survived the storage period (r = 0.89), the average probability of infection (PPinf ) (r = 0.44) and the storage time (Storage) (r = 0.08). This model allowed assessing the impact of different factors influencing the risk of acquiring trichinellosis. The model may thus help to select possible strategies to reduce the risk in the chain of by-products of pork production. © 2015 Blackwell Verlag GmbH.

Full Text Available Background: Staphylococcus aureus and Shiga toxin producing Escherichia coli O157:H7 (EHEC are significant foodborne pathogens worldwide. While S. aureus can cause mild superficial skin infections or life-threatening bacteremia and endocarditis, as well as toxininduced cases such as toxic shock syndrome; E. coli O157:H7 can cause symptoms from mild diarrhea to severe hemorrhagic colitis (HC, hemolytic uremic syndrome (HUS, thrombotic thrombocytopenic purpura (TTP. Objectives: The objectives of this study were to find out the prevalence and seasonal distribution of S. aureus in 214 frozen raw meat (turkey, chicken and beef and the prevalence of E. coli O157:H7 in 70 raw beef with the characterization of the E. coli O157:H7 isolate by multiplex polymerase chain reaction (PCR. Materials and Methods: For the detection of S. aureus, a total of 214 frozen raw meat samples including 74 turkey meat, 70 chicken meat and 70 beef cuts (approximately 2 × 3 cm cubic parts; and for the detection of E. coli O157:H7, a total of 70 frozen raw beef samples that all were produced from national companies and consumed in Ağrı, Turkey were analyzed. Results: Out of 214 meat samples, 25.7 % (18/70 of the beef, 11.4 % (8/74 of the chicken meat, and 5.4 % (4/70 of the turkey meat samples were contaminated with S. aureus. Out of 70 frozen raw beef samples, only 1 (1.4% was identified as both Shiga toxin 1 and 2producing E. coli O157:H7 by the detection of stx1, stx2, eaeA, hly, and fliCh7 according to multiplex PCR analysis. Conclusion: Our findings demonstrate that occurrence frequency of S. aureus was higher in frozen raw beef than in raw chicken and turkey meat samples. Although the prevalence of E. coli O157:H7 was low in beef, the presence of virulence genes, especially toxin genesrema in a significant public health concern.

To evaluate the influence of game meat consumption in Chagas disease (CD) transmission, the conditions under which it occurs and the frequency of reports in the literature. Through systematic review, databases PubMed, LILACS, MEDLINE, and SciELO were consulted, and articles written in Portuguese, English, and Spanish were included, with no limitation over publication date. We used the following descriptors: oral, transmission, meat, wild animals, hunt, carnivory, and Chagas disease. Articles that mentioned consumption of animal meat as a form of human transmission of CD were included. We used epidemiological, clinical, and laboratory evidence criteria to confirm cases. Among the 298 articles identified, only six met the eligibility criteria. Only five episodes of oral transmission through wild animal meat or blood consumption were identified. However, in two of them, the possibility of vectorial transmission could not be ruled out. Most reports met the epidemiological, clinical, and laboratory evidence criteria established to support the transmission. Though CD transmission is uncommon, hunting and consumption of wild mammals that serve as Trypanosoma cruzi reservoirs should be discouraged in endemic countries in light of the risks inherent to these practices.

Biogenic amine accumulation was studied in spontaneously fermented sausages (Fuet) manufactured from unfrozen-fresh meat (U-sausages) and frozen-thawed meat (F-sausages). The aim was to investigate whether the frozen storage of raw materials affects the microbial composition and its aminogenic activity during sausage fermentation. Tyramine was the major amine in all sausages. Although the final levels were similar, tyramine accumulated more rapidly in F-sausages, which contained putrescine as the second amine. By contrast, U-sausages accumulated much more cadaverine than putrescine. F-sausages showed a slightly lower pH and free amino acid content as well as higher counts of technological flora (lactic acid and gram positive catalase positive bacteria) and lower counts of enterobacteria. Therefore, to freeze the meat raw materials for few days before sausage manufacture could be a useful practice, especially for the artisan fermented sausages (without starter), because it helps to reduce enterobacteria development and cadaverine production.

Meat consumers around the world are increasingly paying attention to product quality and safety, and are starting to reduce their meat consumption, especially with regard to red meat. This trend is prevalent in households with children who prefer health-certified meat products. Our study compares meat consumption habits in households with and without children or adolescences (0-18 years). A structured questionnaire was distributed to 401 retail purchasers at 12 different points of sales of meat in the Piedmont region in northwest Italy. Socio-demographic variables and quantitative-qualitative meat consumption habits of retail purchasers were investigated. One part of the questionnaire analyzed the relative importance of 12 meat choice purchasing attributes by employing the Best-Worst scaling methodology, a type of choice experiment. Our research found that households without children (subset B) have higher weekly meat consumption habits than those with children (subset A). Alternatively, the households with children (subset A) have a diet characterized by a greater variety of protein sources, such as legumes and fish. Both of the considered subsets preferred trusted butchers for meat buying, with supermarkets as a second choice. However, only consumers of subset A bought meat from farm butchers. Our team performed a consumer analysis to identify meat consumption patterns in the two considered subsets. Simultaneously, a Best-Worst analysis evidenced several choice attributes with different relevance for the two investigated samples segmentation in three clusters of purchase.

Full Text Available Abstract Background The world-wide increase of foodborne infections with antibiotic resistant pathogens is of growing concern and is designated by the World Health Organization as an emerging public health problem. Thermophilic Campylobacter have been recognised as a major cause of foodborne bacterial gastrointestinal human infections in Switzerland and in many other countries throughout the world. Poultry meat is the most common source for foodborne cases caused by Campylobacter. Because all classes of antibiotics recommended for treatment of human campylobacteriosis are also used in veterinary medicine, in view of food safety, the resistance status of Campylobacter isolated from poultry meat is of special interest. Methods Raw poultry meat samples were collected throughout Switzerland and Liechtenstein at retail level and examined for Campylobacter spp. One strain from each Campylobacter-positive sample was selected for susceptibility testing with the disc diffusion and the E-test method. Risk factors associated with resistance to the tested antibiotics were analysed by multiple logistic regression. Results In total, 91 Campylobacter spp. strains were isolated from 415 raw poultry meat samples. Fifty-one strains (59% were sensitive to all tested antibiotics. Nineteen strains (22% were resistant to a single, nine strains to two antibiotics, and eight strains showed at least three antibiotic resistances. Resistance was observed most frequently to ciprofloxacin (28.7%, tetracycline (12.6%, sulphonamide (11.8%, and ampicillin (10.3%. One multiple resistant strain exhibited resistance to five antibiotics including ciprofloxacin, tetracycline, and erythromycin. These are the most important antibiotics for treatment of human campylobacteriosis. A significant risk factor associated with multiple resistance in Campylobacter was foreign meat production compared to Swiss meat production (odds ratio = 5.7. Conclusion Compared to the situation in other

Clostridium difficile has been shown to be a nosocomial pathogen associated with diarrhoea and pseudomembranous colitis in hospitalised patients and the infection is believed to be acquired nosocomially. Recent studies have shown the occurrence of C. difficile in food animals which may act as a source of infection to humans.The aim of this study was to determine the occurrence of C. difficile in retail raw beef, cow, sheep, goat, camel and buffalo meat in Iran. From April to October 2012, a total of 660 raw meat samples from beef, cow, sheep, goat, camel and buffalo were purchased from 49 butcheries in Isfahan and Khuzestan provinces, Iran, and were evaluated for the presence of C. difficile using a method including selective enrichment in C. difficile broth, subsequent alcohol shock-treatment and plating onto C. difficile selective medium. C. difficile isolates were tested for the presence of toxin genes and were typed using PCR ribotyping. In this study, 13 of 660 meat samples (2%) were contaminated with C. difficile. The highest prevalence of C. difficile was found in buffalo meat (9%), followed by goat meat (3.3%), beef meat (1.7%), cow (0.94%) and sheep meat (0.9%). Seven of the 13C. difficile strains (53.9%) were positive for tcdA, tcdB and cdtB toxin genes and were classified as ribotype 078. Four strains (30.8%) were positive tcdA, and tcdB, and one strain (7.7%) was possessed only tcdB. The remaining isolate was non-toxigenic. Susceptibilities of 13C. difficile isolates were determined for 11 antimicrobial drugs using the disk diffusion assay. Resistance to clindamycin, gentamycin, and nalidixic acid was the most common finding. To our knowledge, the present study is the first report of the isolation of C. difficile from raw buffalo meat. This study indicates the potential importance of food, including buffalo meat, as a source of transmission of C. difficile to humans.

Contact with raw meat could represent a risk for Toxocara infection. We assessed the association of Toxocara infection with an occupation of meat worker though a case-control seroprevalence study of 124 meat workers and 248 subjects without this occupation. Sera of participants was analyzed for the presence of anti-Toxocara IgG antibodies. One (0.8%) of the 124 meat workers, and 5 (2.0%) of the 248 controls were positive for anti-Toxocara IgG antibodies (OR=0.39; 95% CI: 0.04-3.41; P=0.66). The seropositive meat worker was a male aged 28 years old, without vision impairment. None of the work characteristics i.e. frequency of contact with raw meat, use of safety practices, history of splashes at face with blood or raw meat, and injuries with sharp material at work was associated with Toxocara exposure. Seroprevalence of Toxocara infection was significantly higher (P=0.04) in meat workers with consumption of boar meat (1/6: 16.7%) than in those without this consumption (0/117: 0%). We conclude that meat workers do not have a higher risk for Toxocara infection than subjects without this occupation do. The 2% seroprevalence of Toxocara infection found in control subjects might suggest a low seroprevalence of this infection among people with other occupations in Durango City. However, additional case-control studies with larger sample sizes to confirm our results are needed. PMID:26508909

The purpose of the study was to examine temporal changes in meat/poultry/fish consumption patterns between 1995 and 2011–2012 in the Australian population. Meat/poultry/fish consumption from all food sources, including recipes, was analysed by gender, age group, and socio-economic status using 24-h recall data from the 1995 National Nutrition Survey (n = 13,858) and the 2011–2012 National Nutrition and Physical Activity Survey (n = 12,153). The overall proportion of people consuming meat/poultry/fish remained stable (91.7% versus 91.3%, p = 0.55), but a shift in the type of meat consumed was observed. Red meat, including beef and lamb, was consumed by fewer people over the time period (from 56% to 49%), whereas poultry consumption increased (from 29% to 38%). Amounts of all meat/poultry/fish consumed were reportedly higher in 2011–2012 compared with 1995. This resulted in similar (red meat, and processed meat) or slightly higher (poultry, and fish) per-capita intakes in 2011–2012. The magnitude of change of consumption varied between children and adults, and by gender. Monitoring trends in consumption is particularly relevant to policy makers, researchers and other health professionals for the formulation of dietary recommendations and estimation of potential health outcomes.

A renewed interest in the pathogenic potential of Alaria alata mesocercariae emerged over the last 10years as a result of increased findings of this parasite in feral pigs during official examination for Trichinella spp. Cases of food associated human alariosis in North America suggest that a risk associated with the consumption of traditional raw cured products from infected wild boar meat cannot be neglected because the commonly applied preservation techniques may not necessarily kill the mesocercariae. In addition, changes in consumer behavior and new preparation methods for game meat (e.g. pink roasting and grilling) may increase the risk for food-associated parasitic infections. Thus, there is a strong need for the evaluation of the tenacity of A. alata mesocercariae against different physical and chemical influences as pertaining to common preservation and preparation techniques. Against this backdrop the aim of our work was a sound analysis of the survivability of A. alata mesocercariae during curing, fermentation, cold smoking and drying in raw cured meat products. Eighty three samples of traditional German meat products were prepared from naturally infected game meat and partly spiked with additional vital mesocercariae to achieve an adequate dose of infection. The resultant products were examined chronologically for dead and viable A. alata mesocercariae with the Alaria mesocercariae migration technique. After 24h of production, vital A. alata mesocercariae were still found in raw type sausages but no vital parasites were detected in the final products. Based on these results a possible risk for the consumer for an infection with A. alata mesocercariae through the consumption of contaminated raw cured products can be largely ruled out if the respective food technological procedures are carried out properly. However, a risk for the consumer cannot be excluded in cases of very early consumption of these products. Copyright © 2014 Elsevier B.V. All rights

Full Text Available In this study, 384 persons have been subjected to questionnaire made in order to determine the red meat consumption and preferences of the people living in the central district of Tekirdağ province. In the study it was determined that all the consumers consumed red meat. According to the findings of the research, the annual red meat consumption per capita was determined to be 34.22 kg. Considering the red meat consumption of the people subjected to research, it was determined that beef meat was the most preferred kind among all the other kinds of red meat. In the study, it was determined that in red meat buying place preference consumers prefer traditional retailers such as butcher been specialized. Consumers prefer red meat due to be the most nutritious, respectively be healthy, delicious, habit and easy to access. It was determined that 47.5% of consumers participated in the study were ready to pay extra for red meat in the food safety. It was determined 75.6% people participated in the study consume more red meat if the price of red meat cheapens. A logit model was used for analyzing the factors that influence the red meat consumption of the families participating in this research. According to the logit model results, it was determined that the families’ red meat consumption amount is affected from statistical variables such as; number of family members, education level, spouse's employment status, income, cheapening of the price of red meat .

High consumption of meat has been linked with the risk for obesity and chronic diseases. This could partly be explained by the association between meat and lower-quality diet. We studied whether high intake of red and processed meat was associated with lower-quality dietary habits, assessed against selected nutrients, other food groups and total diet. Moreover, we studied whether meat consumption was associated with obesity, after adjustment for all identified associations between meat and food consumption. The nationally representative cross-sectional study population consisted of 2190 Finnish men and 2530 women, aged 25-74 years. Food consumption over the previous 12 months was assessed using a validated 131-item Food Frequency Questionnaire. Associations between nutrients, foods, a modified Baltic Sea Diet Score and meat consumption (quintile classification) were analysed using linear regression. The models were adjusted for age and energy intake and additionally for education, physical activity and smoking. High consumption of red and processed meat was inversely associated with fruits, whole grain and nuts, and positively with potatoes, oil and coffee in both sexes. Results separately for the two types of meat were essentially similar. In a linear regression analysis, high consumption of meat was positively associated with body mass index in both men and women, even when using a model adjusted for all foods with a significant association with meat consumption in both sexes identified in this study. The association between meat consumption and a lower-quality diet may complicate studies on meat and health.

The association between meat consumption and risk of colorectal cancer has been controversial. We examined this question in a large prospective cohort study in Japan. From June through August 1990, 47,605 residents, aged 40-64 years, of Miyagi Prefecture in northern Japan completed a self-administered questionnaire, including a food frequency questionnaire. In the study population, we observed 474 incident cases of colorectal cancer during 11 years of follow-up, to March 2001. We used the Cox proportional hazards model to estimate the relative risk of colorectal cancer (colorectum, colon, rectum and proximal colon and distal colon) according to each of the categories of meat intake (total meat, beef, pork, ham or sausage, chicken and liver), with adjustment for sex, age and other potentially confounding variables. The multivariate relative risk of colorectal cancer in the highest category of total meat consumption compared with the lowest was 1.14 [95% confidence interval (CI)=0.85-1.53; P-trend=0.22]. We also found no significant association between total meat consumption and the risk of sub-site of colorectal cancer. In conclusion, our data do not support the hypothesis that meat consumption is a risk factor for colorectal cancer.

Full Text Available The article analyses possible variants of growth of the level of consumption of meat products (beef, pork, and poultry during the nearest 6 years. The article considers, as a basic variant, planned indicators provided by the Institute of Agrarian Economy and approved in “Strategy of Development of the Agrarian Sector for the Period until 2020”. Based on the time series of meat products consumption during 2000 – 2012, the article builds a forecast of consumption until 2020 using methods of econometric analysis. The article compares the obtained forecast indicators with official indicators, on the basis of which a conclusion is made with respect to groundlessness of planned indicators of beef consumption, for realisation of which the 15% annual growth is needed. In order to specify the level of meat products consumption depending on the level of income, the whole population was presented in the form of three groups: under-provided (40%, averagely provided (30% and well-provided (30%. Optimisation task for maximum of caloricity of the meat products basket, with availability of budget and production (built up on the forecast restrictions, was solved for each group. In the result an optimal ration, which differs significantly both in composition and caloricity, was obtained for each group. Moreover, the article shows that in order to achieve these meat products baskets, it is necessary to bring beef import up to 210 thousand tonnes and the unclaimed 190 thousand tonnes of pork and 210 tonnes of poultry could be exported.

High iron load and red meat consumption could increase the risk of cardiovascular diseases (CVDs). As red meat is the main source of heme iron, which is in turn a major determinant of increased iron load, adverse cardiometabolic effects of meat consumption could be mediated by increased iron load. The object of the study was to assess whether associations between red meat consumption and CVD risk are mediated by iron load in a population-based human study. We evaluated relations between red meat consumption, iron load (plasma ferritin), and risk of CVD in the prospective EPIC-Heidelberg Study using a case-cohort sample including a random subcohort (n = 2738) and incident cases of myocardial infarction (MI, n = 555), stroke (n = 513), and CVD mortality (n = 381). Following a 4-step mediation analysis, associations between red meat consumption and iron load, red meat consumption and CVD risk, and iron load and CVD risk were assessed by multivariable regression models before finally testing to which degree associations between red meat consumption and CVD risk were attenuated by adjustment for iron status. Red meat consumption was significantly positively associated with ferritin concentrations and MI risk [HR per 50 g daily intake: 1.18 (95% CI: 1.05, 1.33)], but no significant associations with stroke risk and CVD mortality were observed. While direct associations between ferritin concentrations and MI risk as well as CVD mortality were significant in age- and sex-adjusted Cox regression models, these associations were substantially attenuated and no longer significant after multivariable adjustment for classical CVD risk factors. Strikingly, ferritin concentrations were positively associated with a majority of classical CVD risk factors (age, male sex, alcohol intake, obesity, inflammation, and lower education). Increased ferritin concentrations may be a marker of an overall unfavorable risk factor profile rather than a mediator of greater CVD risk due to meat

Several studies have suggested differential health effects in relation to different meat composition in Western population. The purpose of the study was to examine secular trends in meat and seafood consumption patterns among Chinese adults between 1991 and 2011. Our longitudinal data are from 21,144 adults aged 18-75 in the China Health and Nutrition Survey, prospective cohort study. We assessed the intakes of meat and subtypes with three 24-h dietary recalls. We conducted multilevel mixed-effect logistic and linear regression models to examine meat consumption dynamics. The proportions of Chinese adults who consumed red meat, poultry and seafood increased from 65.7% in 1991 to 86.1% in 2011, from 7.5 to 20.9% and from 27.4 to 37.8%, respectively. With rapid decrease in meat intakes since 2009, the intakes of total meat, red meat, poultry and seafood among their consumers were 86.7 g/day, 86.4 g/day, 71.0 g/day and 70.3 g/day in 2011, respectively, which were just slightly higher compared with those in 1991. Fatty fresh pork has been predominantly component of total meat overtime, which consituted 54.0% of total meat intake, 80.0% of fresh red meat intake and 98.7% of fatty fresh red meat intake in 2011. Over the past two decades, meat consumption patterns of Chinese adults have been characterized by having a predominant intake of fatty fresh pork, suboptimal intakes of seafood and increased proportion of adults having excessive intakes of red meat and poultry overtime.

Too sweet to eat: Exploring the effects of cuteness on meat consumption.

Zickfeld, Janis H; Kunst, Jonas R; Hohle, Sigrid M

2018-01-01

Although daily meat consumption is a widespread habit, many individuals at the same time put a high value on the welfare of animals. While different psychological mechanisms have been identified to resolve this cognitive tension, such as dissociating the animal from the consumed meat or denying the animal's moral status, few studies have investigated the effects of the animal's appearance on the willingness to consume its meat. The present article explored how the perception of cuteness influences hypothetical meat consumption. We hypothesized that cuter animals would reduce the willingness to consume meat, and that this relationship would be mediated by empathy felt towards the animal. Across four pre-registered studies sampling 1074 US and Norwegian participants, we obtained some support for this prediction in the US but to a lesser degree in Norway. However, in all studies an indirect mediation effect of cuteness on meat consumption going through empathy towards the animal was observed. We also explored possible moderating and additional mediating mechanisms of trait pro-social orientation, caretaking intentions and sex effects for which we found mixed evidence. Theoretical and practical implications of the findings are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Meat consumption is a major risk factor for hepatitis E virus infection.

Directory of Open Access Journals (Sweden)

Ed Slot

Full Text Available The incidence of autochthonous hepatitis E virus genotype 3 (HEV gt3 infections in Western Europe is high. Although pigs are a major reservoir of the virus, the exact sources and transmission route(s of HEV gt3 to humans remain unclear.To determine the role of meat consumption at a population level, the seroprevalence of anti-HEV IgG antibodies was compared between Dutch blood donors with a vegetarian lifestyle and donors who consume meat on a daily basis.The age-weighted anti-HEV IgG seroprevalence among donors not eating meat was significantly lower than among meat-eating donors (12.4% vs 20.5%, p = 0.002. For both groups the prevalence strongly increased with age and the difference in prevalence was apparent for all age groups.Compared with meat-eating donors, the incidence of HEV infection is significantly lower among donors not eating meat, indicating that meat consumption is a major risk factor for HEV infection.

Full Text Available Misuse of fluoroquinolones in livestock production may lead to the presence of their residues in tissues of meat animals after slaughter, constituting health hazards to consumers. The present study was designed to screen for residues of three fluoroquinolones (ciprofloxacin, norfloxacin and ofloxacin in raw meat. Microbiological assay, followed by High Performance Liquid Chromatography (HPLC was used to screen three hundred and twenty samples of beef, chicken, pork and chevon purchased from open markets. Initial screening by microbiological assay revealed that 50%, 55%, 40% and 40% of beef, chicken, pork and chevon, respectively were positive for residues of antibiotics. Further analysis by HPLC with UV detection revealed the presence of ciprofloxacin, norfloxacin and ofloxacin at varying concentrations in the meat samples. Ofloxacin was the least in frequency and abundance in all meat types. Results obtained in this study have implications for public health and will lead to steps that will further enhance the safety of animal foods in order to protect consumers and the animal production industry

Atlanta is a relatively large market for goat meat. As in most metropolitan areas around the U.S., goat-meat consumption has grown steadily in Atlanta over the past decade (Northwest Cooperative Development Center 2005; Nettles and Bukenya 2004). This growth is attributed to the influx of immigrants from goat-meat-eating countries into the U.S. over the same period (Gipson 1999). The increase in demand for goat meat has made the U.S. a net importer of competitively priced goat meat from Austr...

The quantification of meat proportions in raw and boiled sausage according to the recipe was evaluated using three different calibrators. To measure the DNA contents from beef, pork, sheep (mutton), and horse, a tetraplex real-time PCR method was applied. Nineteen laboratories analyzed four meat products each made of different proportions of beef, pork, sheep, and horse meat. Three kinds of calibrators were used: raw and boiled sausages of known proportions ranging from 1 to 55% of meat, and a dilution series of DNA from muscle tissue. In general, results generated using calibration sausages were more accurate than those resulting from the use of DNA from muscle tissue, and exhibited smaller measurement uncertainties. Although differences between uses of raw and boiled calibration sausages were small, the most precise and accurate results were obtained by calibration with fine-textured boiled reference sausages.

Consumers rely heavily on fresh meat color as an indicator of wholesomeness at the point of sale, whereas cooked color is exploited as an indicator of doneness at the point of consumption. Deviations from the bright cherry-red color of fresh meat lead to product rejection and revenue loss. Myoglobin is the sarcoplasmic heme protein primarily responsible for the meat color, and the chemistry of myoglobin is species specific. The mechanistic interactions between myoglobin and multiple extrinsic and intrinsic factors govern the color of raw as well as cooked meats. The objective of this review is to provide an overview of the current research in meat color and how the findings are applied in the meat industry. Characterizing the fundamental basis of myoglobin's interactions with biomolecules in postmortem skeletal muscles is necessary to interpret the chemistry of meat color phenomena and to engineer innovative processing strategies to minimize meat discoloration-induced revenue loss to the agricultural economy.

The polymorphic gene NAT2 is a major determinant of N-acetyltransferase activity and, thus, may be responsible for differences in one's ability to bioactivate heterocyclic amines, a class of procarcinogens in cooked meat. An unusually marked geographic variation in enzyme activity has been described for NAT2. The present study re-examines the international direct correlation reported for meat intake and colorectal cancer (CRC) incidence, and evaluates the potential modifying effects of NAT2 phenotype and other lifestyle factors on this correlation. Country-specific CRC incidence data, per capita consumption data for meat and other dietary factors, prevalence of the rapid/intermediate NAT2 phenotype, and prevalence of smoking for 27 countries were used. Multiple linear regression models were fit and partial correlation coefficients (PCCs) were computed for men and women separately. Inclusion of the rapid/intermediate NAT2 phenotype with meat consumption improved the fit of the regression model for CRC incidence in both sexes (males-R (2) = 0.78, compared to 0.70 for meat alone; p for difference in model fit-0.009; females-R (2) = 0.76 compared to 0.69 for meat alone; p = 0.02). Vegetable consumption (inversely and in both sexes) and fish consumption (directly and in men only) were also weakly correlated with CRC, whereas smoking prevalence and alcohol consumption had no effects on the models. The PCC between NAT2 and CRC incidence was 0.46 in males and 0.48 in females when meat consumption was included in the model, compared to 0.14 and 0.15, respectively, when it was not. These data suggest that, in combination with meat intake, some proportion of the international variability in CRC incidence may be attributable to genetic susceptibility to heterocyclic amines, as determined by NAT2 genotype.

Nutritional and social aspects of consumption of ostrich meat: the case of Spain

Full Text Available The consumption of ostrich meat was introduced into Europe in a relatively short time. Considered even today as an exotic meat, its inclusion in the usual sources of animal protein in our context has been repeatedly assessed, because it converge some of the most interesting nutritional characteristics of poultry and red meat. Over ten years later, the consumption of ostrich meat continues crossing a road that lies increasingly away from the exotic to become very slow, in usual. Although information on their nutritional value is still limited, we have more data showing protein values quite similar to other meats but with a smaller proportion of histidine and serine; fat values close to poultry meat low in fat; cholesterol values, vary according to the court, but similar to beef or chicken, and an improved lipid profile compared to the meat of turkey meat, lamb or beef. The information on its vitamins and minerals throws elevated iron and vitamin B12, higher amounts of vitamin E and Zn than other types of meat and a low concentration of sodium.

One of the consequences of intense genetic selection for growth of poultry is the recent appearance of abnormalities in chicken breast muscles, such as white striping (characterised by superficial white striations) and wooden breast (characterised by pale and bulged areas with substantial hardness). The aim of this study was to evaluate the quality traits of chicken fillets affected by white striping and wooden breast abnormalities. In two replications, 192 fillets were divided into the following four classes: normal (n=48; absence of any visual defects), white striping (n=48, presence of white striations), wooden breast (n=48; diffusely presence of hardened areas) and white striping/wooden breast (n=48; fillets affected by both abnormalities). Morphology, raw meat texture and technological properties were assessed in both unprocessed (pH, colour, drip loss, cooking loss and cooked meat shear force) and marinated meat (marinade uptake, purge loss, cooking loss and cooked meat shear force). Fillets affected by white striping, wooden breast or both abnormalities exhibited higher breast weights compared with normal fillets (305.5, 298.7, 318.3 and 244.7 g, respectively; Pcooking losses than white-striped fillets for both unprocessed and marinated meats. On the other hand, white-striped fillets showed a moderate decline in marinade and cooking yield. Fillets affected by both abnormalities had the highest (Pcooked meat, drip loss, purge loss and cooked meat shear force were negligible or relatively low and of little practical importance. Thus, the presence of white striping and wooden breast abnormalities impair not only breast meat appearance but also the quality of both raw and marinated meats mainly by reducing water holding/binding abilities.

Several recent investigations have reported high concentrations of lead in samples of minced cervid meat. This paper describes findings from a Norwegian study performed in 2012 among 147 adults with a wide range of cervid game consumption. The main aim was to assess whether high consumption of lead-shot cervid meat is associated with increased concentration of lead in blood. A second aim was to investigate to what extent factors apart from game consumption explain observed variability in blood lead levels. Median (5 and 95 percentile) blood concentration of lead was 16.6 µg/L (7.5 and 39 µg/L). An optimal multivariate linear regression model for log-transformed blood lead indicated that cervid game meat consumption once a month or more was associated with approximately 31% increase in blood lead concentrations. The increase seemed to be mostly associated with consumption of minced cervid meat, particularly purchased minced meat. However, many participants with high and long-lasting game meat intake had low blood lead concentrations. Cervid meat together with number of bullet shots per year, years with game consumption, self-assembly of bullets, wine consumption and smoking jointly accounted for approximately 25% of the variation in blood lead concentrations, while age and sex accounted for 27% of the variance. Blood lead concentrations increased approximately 18% per decade of age, and men had on average 30% higher blood lead concentrations than women. Hunters who assembled their own ammunition had 52% higher blood lead concentrations than persons not making ammunition. In conjunction with minced cervid meat, wine intake was significantly associated with increased blood lead. Our results indicate that hunting practices such as use of lead-based ammunition, self-assembling of lead containing bullets and inclusion of lead-contaminated meat for mincing to a large extent determine the exposure to lead from cervid game consumption. © 2013 Elsevier Inc.

Toxoplasma gondii is an obligate intracellular protozoan that can infect all kind of birds and all mammals including humans and is common throughout the world. The prevalence varies according to social and cultural habits, pet cats in homes and geographic factors. Domestic cats are considered to be an important source of Toxoplasma gondii infection. From January to June 2006, the prevalence of toxoplasmosis was retrospectively monitored from blood samples that had been sent to our laboratory in order to determine the levels of IgM and IgG. All the subjects were women and 2,586 blood samples were investigated with the chemiluminescence immunoassay method. The rates of Toxoplasma gondii IgM antibodies were found to be 3.0% (78/2,586) and that of Toxoplasma gondii IgG antibodies, 69.5% (1.798/2,586). The total rate of positivity of Toxoplasma gondii antibodies was 69.6% (1,801/2,586) and the negativity, 30.4% (785/2,586). The highest positive rates have been reported in the southeastern region of Turkey and the 69.6% detected in our study seems to be the highest rate. Raw meatball consumption is common in our region and raw meat has a high risk of Toxoplasma gondii infection by direct ingestion of tissue cysts. As a result we consider that the high frequency of Toxoplasma gondii seropositivity in this region is due to raw meatball consumption.

The present study was designed to characterize methicillin-resistant staphylococci from raw meat. A total of 126 meat samples were obtained from open markets between February and April, 2015. Antimicrobial susceptibility testing was carried out using the disc diffusion method. Molecular profiling was conducted using 16S rRNA, mecA, nuc, and PVL gene signatures were detected by polymerase chain reaction assay. Fifty isolates of methicillin-resistant Staphylococcus spp. were detected in 26 (52%) pork, 14 (28%) beef and 10 (20%) chicken samples. The staphylococcal isolates were identified through partial 16S ribosomal ribonucleic acid (16S rRNA) nucleotide sequencing, and BLAST analysis of the gene sequence revealed 98%-100% staphylococcal similarity. All isolates from beef and chicken samples amplified the mecA gene, while 100% of the MRSA isolates amplified the PVL gene. The multidrug resistance profile (resistant to ≥1 antimicrobial agent in ≥3 classes of antimicrobial agents) of the staphylococcal isolates showed that 7 isolates were resistant to methicillin, penicillin, clindamycin, chloramphenicol, trimethoprim-sulfamethoxazole, kanamycin, amoxicillin, cloxacillin, erythromycin, vancomycin, and gentamycin. There was a significant regression effect from the multidrug-resistant profile on the number of isolates (p resistant strains within bacterial populations. The findings of the present study indicate that raw meats in the Benin metropolis were possibly contaminated with pathogenic and multi-drug resistant staphylococci strains and therefore could constitute a risk to public health communities.

Effects of salt, kinnow and pomegranate fruit by-product powders on color and oxidative stability of raw ground goat meat stored at 4+/-1 degrees C was evaluated. Five treatments evaluated include: control (only meat), MS (meat+2% salt), KRP (meat+2% salt+2% kinnow rind powder), PRP (meat+2% salt+2% pomegranate rind powder) and PSP (meat+2% salt+2% pomegranate seed powder). Addition of salt resulted in reduction of redness scores. Lightness increased in control and unchanged in others during storage. Redness scores declined and yellowness showed inconsistent changes during storage. Thiobarbituric acid reactive substances (TBARS) values were higher (PPRP>KRP>control>MS. Therefore, these powders have potential to be used as natural antioxidants to minimize the auto-oxidation and salt induced lipid oxidation in raw ground goat meat. Crown Copyright 2010.

The skeletal muscle protein troponin I (TnI) has been characterized as a potential thermally stable and species-specific biomarker of mammalian muscle tissues in raw meat and meat products. This study proposed a technique for the quantification of TnI comprising protein extraction and sandwich enzyme-linked immunosorbent assay (ELISA). The technique is characterized by a TnI detection limit of 4.8 ng/ml with quantifiable concentrations ranging from 8.7 to 52 ng/ml. The method was shown to be suitable for detection of TnI in mammalian (beef, pork, lamb, and horse) meat but not in poultry (chicken, turkey, and duck) meat. In particular, the TnI content in beef was 0.40 3 ± 0.058 mg/g of wet tissue. The TnI estimations obtained for the pork and beef samples using ELISA were comparable to the proteomic analysis results. Thus, the quantitative study of TnI can be a convenient way to assess the mammalian muscle tissue content of various meat products. Copyright © 2015. Published by Elsevier Ltd.

The role of household meat handling and consumption in the transfer of Staphylococcus aureus (S. aureus) from livestock to consumers is not well understood. Examining the similarity of S. aureus colonizing humans and S. aureus in meat from the stores in which those individuals shop can provide insight into the role of meat in human S. aureus colonization. S. aureus isolates were collected from individuals in rural and urban communities in Iowa (n = 3347) and contemporaneously from meat products in stores where participants report purchasing meat (n = 913). The staphylococcal protein A (spa) gene was sequenced for all isolates to determine a spa type. Morisita indices and Permutational Multivariate Analysis of Variance Using Distance Matrices (PERMANOVA) were used to determine the relationship between spa type composition among human samples and meat samples. spa type composition was significantly different between households and meat sampled from their associated grocery stores. spa types found in meat were not significantly different regardless of the store or county in which they were sampled. spa types in people also exhibit high similarity regardless of residential location in urban or rural counties. Such findings suggest meat is not an important source of S. aureus colonization in shoppers.

A total of 160 meat product samples were collected from commercial outlets in Mexico City to investigate the presence of different species of Yersinia by the 4 degrees C enrichment method after 1, 3, 5, and 7 days of incubation using alkaline treatment and isolating in cefsulodin-Irgasan-novobiocin and MacConkey agars with Tween 80. Overall, Yersinia spp. were isolated from 27% of the samples analyzed, whereas 40% of the raw and only 13% of the precooked samples were contaminated. Although 2,970 colonies showed Yersinia characteristics, only 706 (24%) actually corresponded to this genus: 49% were Yersinia enterocolitica, 25% Yersinia kristensenii, 15% Yersinia intermedia, 9% Yersinia frederiksenii, and 2% Yersinia aldovae; 10% corresponded to biotype 2, 2% to biotype 3, and 4% to biotype 4. The presence of Yersinia in raw and cooked meat products represents a health risk for consumers in Mexico, where further clinical studies are needed to assess the epidemiological importance of this pathogen.

The effect of meat consumption on body odor attractiveness.

Axillary body odor is individually specific and potentially a rich source of information about its producer. Odor individuality partly results from genetic individuality, but the influence of ecological factors such as eating habits are another main source of odor variability. However, we know very little about how particular dietary components shape our body odor. Here we tested the effect of red meat consumption on body odor attractiveness. We used a balanced within-subject experimental design. Seventeen male odor donors were on "meat" or "nonmeat" diet for 2 weeks wearing axillary pads to collect body odor during the final 24 h of the diet. Fresh odor samples were assessed for their pleasantness, attractiveness, masculinity, and intensity by 30 women not using hormonal contraceptives. We repeated the same procedure a month later with the same odor donors, each on the opposite diet than before. Results of repeated measures analysis of variance showed that the odor of donors when on the nonmeat diet was judged as significantly more attractive, more pleasant, and less intense. This suggests that red meat consumption has a negative impact on perceived body odor hedonicity.

A role for red and processed meat in the development of colorectal cancer has been proposed based largely on evidence from observational studies in humans, especially in those populations consuming a westernized diet. Determination of causation specifically by red or processed meat is contingent upon identification of plausible mechanisms that lead to colorectal cancer. We conducted a systematic review of the available evidence to determine the availability of plausible mechanistic data linking red and processed meat consumption to colorectal cancer risk. Forty studies using animal models or cell cultures met specified inclusion criteria, most of which were designed to examine the role of heme iron or heterocyclic amines in relation to colon carcinogenesis. Most studies used levels of meat or meat components well in excess of those found in human diets. Although many of the experiments used semi-purified diets designed to mimic the nutrient loads in current westernized diets, most did not include potential biologically active protective compounds present in whole foods. Because of these limitations in the existing literature, there is currently insufficient evidence to confirm a mechanistic link between the intake of red meat as part of a healthy dietary pattern and colorectal cancer risk. Impact statement Current recommendations to reduce colon cancer include the reduction or elimination of red or processed meats. These recommendations are based on data from epidemiological studies conducted among cultures where meat consumption is elevated and consumption of fruits, vegetables, and whole grains are reduced. This review evaluated experimental data exploring the putative mechanisms whereby red or processed meats may contribute to colon cancer. Most studies used levels of meat or meat-derived compounds that were in excess of those in human diets, even in cultures where meat intake is elevated. Experiments where protective dietary compounds were used to mitigate the

Full Text Available Meat consumption has been shown to be associated with cardiovascular disease (CVD risk in Western societies; however, epidemiological data are limited on the Korean population. Therefore, we examined the associations between unprocessed meat consumption and CVD incidence in Korea. Data were derived from the Ansung-Ansan cohort (2001–2012, including 9370 adults (40–69 years without CVD or cancer at baseline. Total unprocessed meat consumption was estimated as the sum of unprocessed red meat (beef, pork, and organ meat and poultry consumption.

This article presents the concept, calculation method, and first results of the "Raw Material Consumption" (RMC) economy-wide material flow indicator for the European Union (EU). The RMC measures the final domestic consumption of products in terms of raw material equivalents (RME), i.e. raw materials used in the complete production chain of consumed products. We employed the hybrid input-output life cycle assessment method to calculate RMC. We first developed a highly disaggregated environmentally extended mixed unit input output table and then applied life cycle inventory data for imported products without appropriate representation of production within the domestic economy. Lastly, we treated capital formation as intermediate consumption. Our results show that services, often considered as a solution for dematerialization, account for a significant part of EU raw material consumption, which emphasizes the need to focus on the full production chains and dematerialization of services. Comparison of the EU's RMC with its domestic extraction shows that the EU is nearly self-sufficient in biomass and nonmetallic minerals but extremely dependent on direct and indirect imports of fossil energy carriers and metal ores. This implies an export of environmental burden related to extraction and primary processing of these materials to the rest of the world. Our results demonstrate that internalizing capital formation has significant influence on the calculated RMC.

Compared with Raw Bovine Meat, Boiling but Not Grilling, Barbecuing, or Roasting Decreases Protein Digestibility without Any Major Consequences for Intestinal Mucosa in Rats, although the Daily Ingestion of Bovine Meat Induces Histologic Modifications in the Colon.

Cooking may impair meat protein digestibility. When undigested proteins are fermented by the colon microbiota, they can generate compounds that potentially are harmful to the mucosa. This study addressed the effects of typical cooking processes and the amount of bovine meat intake on the quantity of undigested proteins entering the colon, as well as their effects on the intestinal mucosa. Male Wistar rats (n = 88) aged 8 wk were fed 11 different diets containing protein as 20% of energy. In 10 diets, bovine meat proteins represented 5% [low-meat diet (LMD)] or 15% [high-meat diet (HMD)] of energy, with the rest as total milk proteins. Meat was raw or cooked according to 4 processes (boiled, barbecued, grilled, or roasted). A meat-free diet contained only milk proteins. After 3 wk, rats ingested a (15)N-labeled meat meal and were killed 6 h later after receiving a (13)C-valine injection. Meat protein digestibility was determined from (15)N enrichments in intestinal contents. Cecal short- and branched-chain fatty acids and hydrogen sulfide were measured. Intestinal tissues were used for the assessment of protein synthesis rates, inflammation, and histopathology. Meat protein digestibility was lower in rats fed boiled meat (94.5% ± 0.281%) than in the other 4 groups (97.5% ± 0.0581%, P HMD) and on myeloperoxidase activity in the proximal colon (HMD > LMD), but not on other outcomes. The ingestion of bovine meat, whatever the cooking process and the intake amount, resulted in discrete histologic modifications of the colon (epithelium abrasion, excessive mucus secretion, and inflammation). Boiling bovine meat at a high temperature (100°C) for a long time (3 h) moderately lowered protein digestibility compared with raw meat and other cooking processes, but did not affect cecal bacterial metabolites related to protein fermentation. The daily ingestion of raw or cooked bovine meat had no marked effect on intestinal tissues, despite some slight histologic modifications

Beef and beyond: exploring the meat consumption practices of Christians in India

OpenAIRE

Staples, J

2015-01-01

Meat-eating in India cannot be analysed simply as a marker of ritual impurity: the culinary experiences of South Indian Christians also indicate the importance of meat in forging positive identities. In this paper, I draw out some of the fine-grained distinctions made by my informants in relation to meat-eating, which suggest that its consumption is shaped not only by caste and religion, but in relation to gender, age, status and other personal considerations. Secondly, I attempt to situate t...

Greater consumption of red and processed meat has been associated with an increased risk of colorectal cancer in several recent meta-analyses. Heterocyclic amines (HCAs) have been hypothesized to underlie this association. In this prospective analysis conducted within the Multiethnic Cohort Study, we examined whether greater consumption of total, red or processed meat was associated with the risk of colorectal cancer among 165,717 participants who completed a detailed food frequency questionnaire at baseline. In addition, we examined whether greater estimated intake of HCAs was associated with the risk of colorectal cancer among 131,763 participants who completed a follow-up questionnaire that included a meat-cooking module. A total of 3,404 and 1,757 invasive colorectal cancers were identified from baseline to the end of follow-up and from the date of administration of the meat-cooking module to the end of follow-up, respectively. Proportional hazard models were used to estimate basic and multivariable-adjusted relative risks (RRs) and 95% confidence intervals for colorectal cancer associated with dietary exposures. In multivariable models, no association with the risk of colorectal cancer was detected for density-adjusted total meat (RR(Q5 vs. Q1) = 0.93 [0.83-1.05]), red meat (RR = 1.02 [0.91-1.16]) or processed meat intake (RR = 1.06 [0.94-1.19]) or for total (RR = 0.90 [0.76-1.05]) or specific HCA intake whether comparing quintiles of dietary exposure or using continuous variables. Although our results do not support a role for meat or for HCAs from meat in the etiology of colorectal cancer, we cannot rule out the possibility of a modest effect. Copyright © 2012 UICC.

Reducing meat consumption in today’s consumer society: questioning the citizen-consumer gap

Game meat from animals killed by lead ammunition may expose consumers to lead. We assessed the risk related to lead intake from meat consumption of white-tailed deer and moose killed by lead ammunition and documented the perception of hunters and butchers regarding this potential contamination. Information on cervid meat consumption and risk perception were collected using a mailed self-administrated questionnaire which was addressed to a random sample of Quebec hunters. In parallel, 72 samples of white-tailed deer (n = 35) and moose (n = 37) meats were collected from voluntary hunters and analysed for lead content using inductively coupled plasma-mass spectrometry. A risk assessment for people consuming lead shot game meat was performed using Monte Carlo simulations. Mean lead levels in white-tailed deer and moose killed by lead ammunition were 0.28 and 0.17 mg kg(-1) respectively. Risk assessment based on declared cervid meat consumption revealed that 1.7% of the surveyed hunters would exceed the dose associated with a 1 mmHg increase in systolic blood pressure (SBP). For consumers of moose meat once, twice or three times a week, simulations predicted that 0.5%, 0.9% and 1.5% of adults would be exposed to a dose associated with a 1 mmHg increase in SBP, whereas 0.9%, 1.9% and 3.3% of children would be exposed to a dose associated with 1 point intelligence quotient (IQ) decrease, respectively. For consumers of deer meat once, twice or three times a week, the proportions were 1.6%, 2.9% and 4% for adults and 2.9%, 5.8% and 7.7% for children, respectively. The consumption of meat from cervids killed with lead ammunition may increase lead exposure and its associated health risks. It would be important to inform the population, particularly hunters, about this potential risk and promote the use of lead-free ammunition.

Conservatism predicts lapses from vegetarian/vegan diets to meat consumption (through lower social justice concerns and social support).

Science.gov (United States)

Hodson, Gordon; Earle, Megan

2018-01-01

Lapses from vegetarian and vegan (i.e., veg*n) food choices to meat consumption are very common, suggesting that sustaining veg*nism is challenging. But little is known about why people return to eating animals after initially deciding to avoid meat consumption. Several potential explanatory factors include personal inconvenience, meat cravings, awkwardness in social settings, or health/nutrition concerns. Here we test the degree to which political ideology predicts lapsing to meat consumption. Past research demonstrates that political ideology predicts present levels of meat consumption, whereby those higher in right-wing ideologies eat more animals, even after controlling for their hedonistic liking of meat (e.g., Dhont & Hodson, 2014). To what extent might political ideology predict whether one has lapsed from veg*n foods back to meat consumption? In a largely representative US community sample (N = 1313) of current and former veg*ns, those higher (vs. lower) in conservatism exhibited significantly greater odds of being a former than current veg*n, even after controlling for age, education, and gender. This ideology-lapsing relation was mediated (i.e., explained) by those higher (vs. lower) in conservatism: (a) adopting a veg*n diet for reasons less centered in justice concerns (animal rights, environment, feeding the poor); and (b) feeling socially unsupported in their endeavor. In contrast, factors such as differential meat craving or lifestyle inconvenience played little mediational role. These findings demonstrate that ideology and justice concerns are particularly relevant to understanding resilience in maintaining veg*n food choices. Implications for understanding why people eat meat, and how to develop intervention strategies, are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Evidence of anticancer properties of garlic for different cancer sites has been reported previously in in vitro and in vivo experimental studies but there is limited epidemiologic evidence on the association between garlic and lung cancer. We examined the association between raw garlic consumption and lung cancer in a case-control study conducted between 2005 and 2007 in Taiyuan, China. Epidemiologic data was collected by face-to-face interviews from 399 incident lung cancer cases and 466 healthy controls. We used unconditional logistic regression models to estimate crude and adjusted ORs (aOR) and their 95% confidence intervals (CI). Adjusted models controlled for age, sex, average annual household income 10 years ago, smoking, and indoor air pollution. Compared with no intake, raw garlic intake was associated with lower risk of development of lung cancer with a dose-response pattern (aOR for garlic consumption with indoor air pollution and with any supplement use in association with lung cancer. The results of the current study suggest that raw garlic consumption is associated with reduced risk of lung cancer in a Chinese population. This study contributes to the limited research in human population on the association between garlic and lung cancer and advocates further investigation into the use of garlic in chemoprevention of lung cancer.

Full Text Available The residue of ground coffee obtained after the brewing process (spent coffee still contains various functional components with high antioxidant capacity and health benefits, but no attempts have been made to use it as a resource to produce value-added food ingredients. This study evaluates the antioxidant activity of ethanol or hot water extracts from the residues of coffee after brewing. An extraction experiment was carried out using the conventional solid–liquid methods, including ethanol and water as the extraction media at different temperatures and liquid/solid ratios. The antioxidant activity of extracts was tested for total phenolic compound (TPC, 2,2-diphenyl-1-picrylhydrazyl (DPPH, and 2-thiobarbituric acid reactive substances (TBARS using oil emulsion and raw/cooked meat systems. The DPPH radical scavenging activity of the ethanol extracts with heating (HEE and without heating (CEE were higher than that of the hot water extracts (WE. The highest DPPH value of HEE and CEE at 1000 ppm was 91.22% and 90.21%, respectively. In oil emulsion and raw/cooked systems, both the water and ethanol extracts had similar antioxidant effects to the positive control (BHA, but HEE and CEE extracts showed stronger antioxidant activities than WE extract. These results indicated that the ethanol extracts of coffee residue have a strong antioxidant activity and have the potential to be used as a natural antioxidant in meat.

Analyzing the biophysical inputs and outputs embodied in global commodity chains - the case of Israeli meat consumption

Full Text Available The prevailing global livestock industry relies heavily on natural capital and is responsible for high emissions of greenhouse gases (GHG. In recent years, nations have begun to take more of an active role in measuring their resource inputs and GHG outputs for various products. However, up until now, most nations have been recording data for production, focusing on processes within their geographical boundaries. Some recent studies have suggested the need to also embrace a consumption-based approach. It follows that in an increasingly globalized interconnected world, to be able to generate a sustainable food policy, a full systems approach should be embraced. The case of Israeli meat consumption presents an interesting opportunity for analysis, as the country does not have sufficient resources or the climatic conditions needed to produce enough food to support its population. Therefore, Israel, like a growing number of other countries that are dependent on external resources, relies on imports to meet demand, displacing the environmental impact of meat consumption to other countries. This research utilizes a multi-regional consumption perspective, aiming to measure the carbon and land footprints demanded by Israeli cattle and chicken meat consumption, following both domestic production and imports of inputs and products. The results of this research show that the “virtual land” required for producing meat for consumption in Israel is equivalent to 62% of the geographical area of the country. Moreover, almost 80% of meat consumption is provided by locally produced chicken products but the ecological impact of this source is inconsequential compared to the beef supply chain; beef imports comprise only 13% of meat consumption in Israel but are responsible for 71% of the carbon footprint and 83% of the land footprint. The sources of Israel’s meat supply are currently excluded from environmental impact assessments of Israeli processes. However

Consumption of raw or unpasteurized milk and milk products by pregnant women and children.

Science.gov (United States)

2014-01-01

Sales of raw or unpasteurized milk and milk products are still legal in at least 30 states in the United States. Raw milk and milk products from cows, goats, and sheep continue to be a source of bacterial infections attributable to a number of virulent pathogens, including Listeria monocytogenes, Campylobacter jejuni, Salmonella species, Brucella species, and Escherichia coli O157. These infections can occur in both healthy and immunocompromised individuals, including older adults, infants, young children, and pregnant women and their unborn fetuses, in whom life-threatening infections and fetal miscarriage can occur. Efforts to limit the sale of raw milk products have met with opposition from those who are proponents of the purported health benefits of consuming raw milk products, which contain natural or unprocessed factors not inactivated by pasteurization. However, the benefits of these natural factors have not been clearly demonstrated in evidence-based studies and, therefore, do not outweigh the risks of raw milk consumption. Substantial data suggest that pasteurized milk confers equivalent health benefits compared with raw milk, without the additional risk of bacterial infections. The purpose of this policy statement was to review the risks of raw milk consumption in the United States and to provide evidence of the risks of infectious complications associated with consumption of unpasteurized milk and milk products, especially among pregnant women, infants, and children.

Reducing meat consumption is often advised; however, inadvertent nutritional deficiencies during pregnancy may result in residual neurodevelopmental harms to offspring. This study assessed possible effects of maternal diets in pregnancy on adverse substance use among adolescent offspring. Pregnant women and their 13-year-old offspring taking part in a prospective birth cohort study, the Avon Longitudinal Study of Parents and Children (ALSPAC), provided Food Frequency Questionnaire data from which dietary patterns were derived using principal components analysis. Multivariable logistic regression models including potential confounders evaluated adverse alcohol, cannabis, and tobacco use of the children at 15 years of age. Lower maternal meat consumption was associated with greater problematic substance use among 15-year-old offspring in dose-response patterns. Comparing never to daily meat consumption after adjustment, risks were greater for all categories of problem substance use: alcohol, odds ratio OR = 1.75, 95% CI = (1.23, 2.56), p meat consumption disproportionally increased the risks of offspring substance misuse among mothers with optimally functional (homozygous) variants (rs1801198) of the gene transcobalamin 2 gene (TCN2) which encodes the vitamin B12 transport protein transcobalamin 2 implicating a causal role for cobalamin deficits. Functional maternal variants in iron metabolism were unrelated to the adverse substance use. Risks potentially attributable to cobalamin deficits during pregnancy include adverse adolescent alcohol, cannabis, and tobacco use (14, 37, and 23, respectively). Lower prenatal meat consumption was associated with increased risks of adolescent substance misuse. Interactions between TCN2 variant status and meat intake implicate cobalamin deficiencies.

2018-04-12

People who exclude meat from their diets are not only devoid of situational pressures to disengage morally and deny humanlike mental states to animals but also they may be dispositionally more inclined to ascribe human-like qualities to non-human animals than omnivores. The aim of this research was to test whether individual differences in anthropomorphism are related to empathic connection with non-human animals and hence decreased meat consumption. In two studies (N = 588) we confirmed that decreased meat consumption was associated with both increased recognition of human features of animals and increased empathy to animals. Most importantly, our data support a model in which animals' anthropomorphism predicts empathy. Empathy, in turn, increases the importance that potential animal harm plays in dietary choices regarding meat, leading to reduced meat consumption. Copyright © 2018. Published by Elsevier Ltd.

Olive leaves (OL), available in huge amounts from pruning, are known to be a useful source of biologically active compounds. This study investigated the potential application of OL as a supplement to minced beef meat in order to develop a functional product. The effect of OL extract or powder (100 and 150 µg phenols g -1 meat) on the quality and stability of raw and cooked meat during refrigerated storage was examined. Microwave drying at 600 W gave OL with the highest antioxidant quality (evaluated by TEAC/[phenols] (mg mg -1 ) and DPPH/[phenols] (mg mg -1 )) compared with other methods. OL showed an ability to inhibit (P production was 43-65% in control samples and 14-35% in treated samples). OL also improved the technological quality of the meat, decreasing (P functional meat products of good technological quality that remain stable during storage. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Full Text Available Background and Aims. Hyperferritinemia has been related with a wide spectrum of pathologies, including diabetes, cardiovascular disease, neurodegenerative disorders, and metabolic syndrome. The aim of this study was to investigate the association between hyperferritinemia and iron consumption. Methods and Results. Serum ferritin concentration was evaluated in 66 presumed healthy men, along with other clinical and biochemical markers of chronic diseases. A three-day food questionnaire was applied for nutrition information. Hyperferritinemia was a condition found in 13.4% of the volunteers analyzed. Significant correlations were found between serum ferritin concentration and metabolic syndrome parameters (HDL cholesterol, triglycerides, and fasting glucose as well as an increase of the serum ferritin mean value with the number of risk factors of metabolic syndrome. Also, oxidative stress markers (carbonyl groups, AOPP, and glycated hemoglobin, hepatic damage markers (GGT, SGOT, and parameters related to insulin resistance (HOMA, blood insulin, and blood glucose correlate significantly with serum ferritin. Volunteers had an excessive iron intake, principally by bread consumption. Analyses of food intake showed that red meat consumption correlates significantly with serum ferritin. Conclusion. Red meat consumption, metabolic syndrome, and chronic disease markers are associated with hyperferritinemia in a population of Chilean men.

Markedly increased red meat consumption is a cancer risk factor, while dietary flavonoids may help prevent the disease. The purpose of this study was to investigate the associations of red meat and flavonoid consumption with cancer risk, based on data from 8024 subjects, drawn from the 2004-2008 Cancer Screening Examination Cohort of the Korean National Cancer Center. Hazard ratios (HRs) were obtained by using a Cox proportional hazard model. During the mean follow-up period of 10.1 years, 443 cases were newly diagnosed with cancer. After adjusting for age, there was a significant correlation between cancer risk and the daily intake of ≥43 g of red meat per day (HR 1.31; 95% CI 1.01, 1.71; p = 0.045), and total flavonoid intake tended to decrease cancer risk (HR 0.70; 95% CI 0.49, 0.99; highest vs. lowest quartile; p -trend = 0.073) in men. Following multivariable adjustment, there were no statistically significant associations between flavonoid intake and overall cancer risk in individuals with high levels of red meat intake. Men with low daily red meat intake exhibited an inverse association between flavonoid consumption and cancer incidence (HR 0.41; 95% CI 0.21, 0.80; highest vs. lowest; p -trend = 0.017). Additional research is necessary to clarify the effects of flavonoid consumption on specific cancer incidence, relative to daily red meat intake.

High levels of meat consumption in Belgium may be contributing to increased risk of non-communicable diseases in this population. The objective of this study is to investigate the attitudes and beliefs about vegetarianism and meat consumption among the Belgian population, ultimately to better understand the motivations underlying these dietary behaviours. This cross-sectional study was initiated in March 2011. A total of 2436 individuals from a representative consumer panel from the Flemish and Brussels communities participated. The study sample was evenly distributed by education level and sex (1238 men and 1198 women). An online questionnaire with multiple-choice questions about vegetarianism and meat consumption was completed by all participants. Although representative of the prevalence of vegetarians in the population, the number of vegetarians in the study was low (n = 38); the number of semi-vegetarians (n = 288) and omnivores was high (n = 2031). Vegetarians were more likely than semi-vegetarians to agree that meat production is bad for the environment and that meat consumption is unhealthy. Important reasons for not being vegetarian included lack of interest and awareness, taste, and limited cooking skills. Encouragingly, health and discovering new tastes were seen as the most important motives for considering eating a more vegetarian-based diet. The results of this study highlight the motivations that can be used for encouraging the general public to reduce their meat consumption in favour of a plant-rich diet, and will help to inform more targeted health campaigns for reducing meat consumption in Belgium.

The meat sector in Spain is an important industry. However, traditional consumption is changing as a result of the country's economic crisis and the new structure of households. The objective of the present study was to identify trends in meat consumption in Spain extrapolated to 2016, and the main innovations that should be of interest to firms in the sector. The study was conducted in 2011 using the Delphi method with the participation of 26 experts. The results showed that, while the demand for meat will not vary significantly in amount, it will do so in composition, with chicken replacing beef as the meat of most importance in the shopping basket. In addition, significant growth is expected in certified meat, but the demand for organic meat will not take off. Neither will there be no significant changes in end purchase formats, but there will be a clear trend in consumers' purchasing decision criteria away from price, external appearance and origin towards quality certification and the attributes of the packaging. With respect to end purchase channels, the experts estimate that the current trend will be accentuated with increasing market share for large supermarkets and major distribution brands.

Red meat and processed meat may increase the risk of developing colon cancer. A small amount of red meat, not more than 50 gr. week and avoid processed meats completely, significantly reducing the risk of this disease. The aim of this study was to investigate the frequency of consumption of red meat, meat products and eggs, and chicken meat and fish in high school and college students in Sombor and assume the risk of colon cancer. A survey was conducted on the incidence of these foods alone during their weekly food and on the basis of the obtained data on height and weight, calculated body mass index (BMI). Surveyed a total of 225 adolescents, of which 145 high school students, 115 girls and 32 men and 78 students, 43 girls and 35 men from different places in Vojvodina. 84% of high school students were normally nourished, 46% male and 98% of female students. More than 50% of the male student population is over-nourished. Half of the surveyed male population of red meat daily, while the girls eat more fish and chicken. Male population has higher risk for the development of colon cancer.

Messages aimed at changing eating habits of the elderly are often not persuasive. In two studies, we tested the hypothesis that the persuasiveness of messages regarding the effects of meat consumption on health versus well-being would depend on their factual versus prefactual ('if … then … ') framing. Different groups of elderly participants were presented with different versions of a message describing the possible negative effects of excessive meat consumption. Results of a preliminary study showed that messages about the effects of meat consumption on health and well-being induced a different regulatory concern in recipients, safety and growth concerns respectively. Results of the two main studies then showed that messages about health/safety had stronger effects on participants' involvement, attitudes, and intentions to change eating behaviour when framed in factual rather than prefactual terms. Conversely, messages about well-being/growth had stronger effects when framed in prefactual rather than factual terms. Discussion focuses on how the appropriate framing of messages about meat consumption can effectively promote changes in eating habits of elderly people. Copyright © 2016 Elsevier Ltd.

The colon and rectum are common sites of food-related cancer in developed countries. Recent studies strongly suggest that red meat intake is associated with colon cancer, whereas for rectal cancer such an association still needs to be proved. The aim of the study was to assess the role of total amount and frequency of red meat intake in colorectal carcinogenesis based on published data using meta-analysis methods. The literature published until 2009 was selected from: MEDLINE, PubMed, Scopus, Embase, CancerLit, Google Scholar and Cochrane Library databases. The used search terms were: colorectal cancer, colon cancer, rectal cancer, meat intake, red meat intake, red meat consumption, meat consumption, colorectal cancer risk, colon cancer risk, rectal cancer risk and lifestyle. Articles investigating red meat intake of more often than once a day or 50 g per day were reviewed and selected for further analysis. Twenty-two studies fulfilled the established criteria. A meta-analysis confirmed the carcinogenic effect of the consumption of over 50 g of red meat per day for the colon (relative risk 1.21, 1.07-1.37) but not for the rectum (relative risk 1.30, 0.90-1.89). Red meat intake more frequently than once a day can induce both colonic (relative risk 1.37, 1.09-1.71) and rectal cancer (relative risk 1.43, 1.24-1.64). Red meat intake is associated with elevated risk of developing colorectal cancer. The frequency of red meat consumption rather than total amount of consumed meat is associated with a higher risk of colorectal carcinogenesis.

Toxoplasma gondii is a global protozoan parasite capable of infecting most warm-blooded animals. Although healthy adult humans generally have no symptoms, severe illness does occur in certain groups, including congenitally infected fetuses and newborns, immunocompromised individuals including transplant patients. Epidemiological studies have demonstrated that consumption of raw or undercooked meat products is one of the major sources of infection with T. gondii. The goal of this study was to develop a framework to qualitatively estimate the exposure risk to T. gondii from various meat products consumed in the United States. Risk estimates of various meats were analyzed by a farm-to-retail qualitative assessment that included evaluation of farm, abattoir, storage and transportation, meat processing, packaging, and retail modules. It was found that exposure risks associated with meats from free-range chickens, nonconfinement-raised pigs, goats, and lamb are higher than those from confinement-raised pigs, cattle, and caged chickens. For fresh meat products, risk at the retail level was similar to that at the farm level unless meats had been frozen or moisture enhanced. Our results showed that meat processing, such as salting, freezing, commercial hot air drying, long fermentation times, hot smoking, and cooking, are able to reduce T. gondii levels in meat products. whereas nitrite and/or nitrate, spice, low pH, and cold storage have no effect on the viability of T. gondii tissue cysts. Raw-fermented sausage, cured raw meat, meat that is not hot-air dried, and fresh processed meat were associated with higher exposure risks compared with cooked meat and frozen meat. This study provides a reference for meat management control programs to determine critical control points and serves as the foundation for future quantitative risk assessments.

After fossil fuels, agricultural production and fisheries are industries with the largest impact on the environment in terms of greenhouse gas (GHG) emissions, especially in the production of ruminant meats such as beef, veal or lamb. In order to reduce this environmental impact, consumers can change their food consumption habits to utilize less polluting products such as white meats or vegetable food products. We analyze whether or not a CO2 equivalent (CO2-eq) tax policy can change consumer...

MARKET CHOICES FOR BROILER CHICKEN MEAT IN THE OPINION

Directory of Open Access Journals (Sweden)

Anna Augustyńska-Prejsnar

2014-09-01

Full Text Available Recently there has, been growing a increase in consumption of poultry meat in Poland. The most important material for slaughter poultry are broilers. Among factors that influence rising demand for poultry meat are: low price, availability of raw materials and promotional campaigns of safe nutrition. Its nutritional and sensory value makes it a choice product. University students are a specific group that has aroused the interest of nutritionists. The students’ lifestyle is characterised by high active social life and intense responsibilities, which ought to be augmented with a carefully chosen diet. The youth do not only have significant impact on the family purchasing decisions but display a strong purchasing power due to financial resources at their disposal and would in the future become mature and rational consumers. The article lists factors that determine purchasing needs, reasons for choice of markets and the consumption frequency of broiler meat. The feeling of lack of other products coupled with current sales promotions were, in the opinion of the students surveyed, often responsible for the decision to purchase of broiler chicken meat. Low price and the ease of preparation were also key reasons for the choice of this meat product. Responding students noted that skinless chicken breast fillet was most commonly consumed.

2008-01-01

The aim of this study was to investigate whether polymorphisms in N-acetyl transferase 1 and 2 modify the association between meat consumption and risk of breast cancer. A nested case-control study was conducted among 24697 postmenopausal women included in the 'Diet, Cancer and Health' cohort study...... (1993-2000). Three hundred and seventy-eight breast cancer cases were identified and matched to 378 controls. The incidence rate ratio (95% confidence interval) for breast cancer was 1.09 (1.02-1.17) for total meat, 1.15 (1.01-1.31) for red meat and 1.23 (1.04-1.45) for processed meat per 25 g daily...... total meat intake and red meat intake and breast cancer risk were confined to intermediate/fast N-acetyl transferase 2 acetylators (P-interaction=0.03 and 0.04). Our findings support an association between meat consumption and breast cancer risk and that N-acetyl transferase 2 polymorphism has...

Meat consumption predicts risk of several chronic diseases. The authors validate the accuracy of meat consumption reported by food frequency questionnaires and the mean of eight 24-hour recalls, using urinary methylhistidine excretion, in 55 Black and 71 White Adventist subjects in Los Angeles and San Diego, California, in 1994-1997. 1-Methylhistidine excretion predicts vegetarian status in Black (p = 0.02) and in White (p = 0.005) subjects. Spearman's correlation coefficients between 1-methylhistidine and estimated meat consumption were usually between 0.4 and 0.6 for both food frequency questionnaires and 24-hour recall data. This is despite the chance collection of dietary recalls and urines from omnivores on meatless days.

Full Text Available The objective of this study is to evaluate the effect of the daily consumption of ostrich meat (lliofemuralis internus and bovine meat (Psoas major on the lipid metabolism in adult mice. The analyses of the centesimal composition of the meats and preparation of the diets were accomplished following the recommendations of the American Institute of Nutrition-AIN-93. Three groups of 150 day-old animals: group I (diet I, with casein, group II (diet II, with ostrich meat, and group III (diet III with bovine meat were fed for 13 weeks with the respective diets and weight gain, food efficiency coefficient, total cholesterol, lipoprotein fractions, hepatic, transaminases and body fat percentage and hepatic fat content were evaluated. No difference (p < 0.05 it was found for weight gain and coefficients for feed efficiency among the groups. Total cholesterol, HDL-cholesterol, LDL-cholesterol, relationship of total cholesterol/HDL-cholesterol, VLDL, triglycerides and hepatic transaminases were also not different among the groups (p < 0.05. This research suggests that the consumption of ostrich meat or thin bovine meat on a daily basis does not raise concerns about weight gain, and an increase in the plasma concentrations of lipoprotein and levels of hepatic transaminase.

Although a large body of epidemiological research suggests that red meat intake increases the risk of colorectal cancer, little is known regarding how such an association varies across populations and types of red meat. The objective of this study was to assess whether an association exists between the intakes of total red meat and pickled red meat and the risk of colorectal cancer in study subjects residing in Newfoundland and Labrador. This case-control study of 1,204 residents of Newfoundland and Labrador was part of a larger study on colorectal cancer. Personal history food frequency questionnaires were used to collect retrospective data from 518 individuals diagnosed with colorectal cancer and 686 controls. Intakes were ranked and divided into tertiles. Logistic regression was used to examine the possible association between meat intakes and colorectal cancer diagnosis while controlling for possible confounding factors. A positive, but non-statistically significant, association between total red meat intake and CRC was observed in this study. Pickled red meat consumption was found to be significantly associated with an increased risk of CRC (men, OR = 2.07, 95% CI 1.37-3.15; women, OR = 2.51, 95% CI 1.45-4.32), the odds ratios increasing with each tertile of consumption, suggesting a dose-response effect. Intake of pickled red meat appears to increase the risk of colorectal cancer in Newfoundland and Labrador.

Volatile compounds in meat and meat products

Directory of Open Access Journals (Sweden)

Monika KOSOWSKA

Full Text Available Abstract Meaty flavor is composed of a few hundreds of volatile compounds, only minor part of which are responsible for the characteristic odor. It is developed as a result of multi-directional reactions proceeding between non-volatile precursors contained in raw meat under the influence of temperature. The volatile compounds are generated upon: Maillard reactions, lipid oxidation, interactions between Maillard reaction products and lipid oxidation products as well as upon thiamine degradation. The developed flavor is determined by many factors associated with: raw material (breed, sex, diet and age of animal, conditions and process of slaughter, duration and conditions of meat storage, type of muscle, additives applied and the course of the technological process. The objective of this review article is to draw attention to the issue of volatile compounds characteristic for meat products and factors that affect their synthesis.

Duck farming is on the raise in the current scenario, but processed products from duck meat are still uncommon to find. Investigating the duck meat qualities during storage will provide information to enhance duck meat utilization. Development of ready-to-eat and ready-to-cook duck meat products is expected to increase and improve non-chicken meat-based protein. The Study was aimed to evaluate the changes in quality characteristics of duck meat sausages preserved by refrigeration (7 ± 1 °C). Duck meat sausages were prepared by utilizing raw and partially cooked duck meat with addition of soy flour at 10% level as a binder. Different quality characteristics like physical and chemical characteristics, proximate composition, and organoleptic characteristics were evaluated. Cooking loss of partially cooked meat sausages was lower than raw duck meat sausages, whereas emulsion stability and 2-thiobarbituric acid (TBA) values of raw duck meat sausages were lesser than partially cooked meat sausages. Cooking loss and emulsion stability decreased in both types of meat sausages, while, 2-TBA values increased as refrigerated storage progressed for 14 days. Percent moisture content of raw duck meat sausages was higher than partially cooked meat sausages, which decreased in both types of meat sausages as refrigerated storage progressed for 14 days. Percent crude protein (CP) and percent ether extract (EE) content of partially cooked duck meat sausages were higher than raw duck meat sausages. Regardless of type of meat used, refrigerated storage of sausages increased CP and EE up to 10th day but decreased upon further storage up to 14th day. Organoleptic scores for raw duck meat sausages were higher than partially cooked duck meat sausages and all the scores decreased with an increase in the storage period. However the scores were within the acceptable limits. The findings prove that, duck meat can be effectively acclaimed as an alternative avenue to meet the escalating

Uncured and nitrite-cured pork were subjected, raw, cooked (65 °C, 15 min) or overcooked (90 °C, 30 min), to an in vitro digestion model, which includes mouth, stomach, duodenum, and colon phases. Heating of uncured meat resulted in a pronounced increase in lipid and protein oxidation products throughout digestion. Nitrite-curing had an antioxidant effect during digestion, but this effect disappeared when the meat was overcooked, resulting in up to ninefold higher 4-hydroxy-2-nonenal concentrations compared with digested nitrite-cured raw and cooked pork. Colonic digesta contained significantly higher concentrations of the NOC-specific DNA adduct O(6)-carboxy-methylguanine when pork underwent a more intense heating procedure, independent of nitrite-curing, depending strongly on the fecal inoculum used. Since processed meats are usually nitrite-cured, the present study suggests that overcooking processed meat is likely to result in the formation of genotoxic compounds during digestion and should, therefore, be avoided.

Milena Alicja Stachelska

2017-01-01

Full Text Available The aim of this study was to design a time-effective method comprising a short pre-enrichment step in a non-selective broth in combination with the TaqMan probe applied in the real-time polymerase chain reaction to detect Yersinia enterocolitica strains in raw pork meat. The method enabled to detect 1 colony forming unit per 25 mg of Yersinia enterocolitica in pork meat. The specificity and reliability of the method was not diminished by the company of microflora naturally present in meat. The method was found successful to detect pathogenic Yersinia enterocolitica strains in pork meat. It is advised to be used for assessing the microbial risk and for controlling the microbial quality of meat and meat products.

This study was aimed at comparing the taste-related compound content in the breast and leg meat from 100-d-old Korean native chickens (KNC-100) and 32-d-old commercial broilers (CB-32) and determining the changes in these compounds during cooking. Cocks from certified meat-type commercial broiler (Ross) and Korean native chicken (Woorimatdag) strains were raised under similar standard commercial conditions, and a total of 10 birds from each breed were slaughtered at 32 and 100 d of age, which represents their market ages, respectively. Raw and cooked meat samples were prepared separately from the breast and leg and analyzed. The KNC-100 showed significantly higher concentrations of inosine 5'-monophosphate, reducing sugars, glutamic acid, linoleic acid, arachidonic acid, and docosahexaenoic acid than CB-32 did. Additionally, significantly higher inosine 5'-monophosphate, cysteine, arachidonic acid, and docosahexaenoic acid concentrations were observed in the breast meat, whereas the leg meat had higher concentration of glutamic acid, oleic acid, and linoleic acid (P cooking process, except oleic and linoleic acids. We suggest that the higher levels of taste-related compounds present in KNC-100 meat compared with CB-32 meat may result in the unique taste of the former meat, as has been previously reported. In addition, the results of this study may provide useful information for selection and breeding programs. ©2014 Poultry Science Association Inc.

In this study a total of 30 raw meat samples obtained from Ankara, Turkey were screened for the presence of Bacillus species. Among the meat samples analyzed, the predominant species isolated was Bacillus circulans; other Bacillus species were identified as Bacillus firmus, Bacillus lentus, Bacillus megaterium, Bacillus licheniformis, Bacillus mycoides, Bacillus sphaericus, and Bacillus cereus. Minced meat samples were more contaminated with Bacillus species than sliced beef sample. From these samples, 242 Bacillus species isolates were obtained, which were investigated for proteolytic and lipolytic activity, associated with meat spoilage. Interestingly, some Bacillus strains produced the highest values of proteolytic/lipolytic activities. Nineteen Bacillus strains were selected among the 242 isolates according to their proteolytic/lipolytic activity with a clear zone diameter of > or =6 mm. The essential oil of Satureja wiedemanniana (Lalem) Velen was also tested against these 19 Bacillus species that had proteolytic and lipolytic activity. The essential oil yield obtained from the aerial parts of the plant was 0.35% (vol/wt). The inhibition zones of the essential oil obtained against all the Bacillus species were in the range of 5.0-12.0 mm. The oil showed high antimicrobial activities against B. licheniformis M 6(26), M 11(16), and M 12(1) strains. B. licheniformis 12(1) showed high lipolytic activity (18.0 mm). Also, B. licheniformis M 6(26) and M 11(16) showed high proteolytic activity (16.0 and 14.0 mm). These results may suggest that an essential oil of S. wiedemanniana can be used as a natural preservative in meat against spoilage bacteria.

Influence of Skin Packaging on Raw Beef Quality: A Review

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available A detailed revision of several aspects related to the application of skin packaging to raw beef was considered. Skin packaging, a relatively new technique derived from vacuum packaging, was developed with the aim of retailing small portions of fresh meat, minced meat, or meat preparations. Above all, the influence of this typology of packaging on the microbial population of raw meat was studied, with particular attention to total viable count, aerobic spoilage bacteria, anaerobic bacteria, Enterobacteriaceae, Brochothrix thermosphacta, and lactic acid bacteria. Moreover, the effect on acidification by LAB was also deepened. As colour is the main characteristic influencing purchase decisions at the point of sale, the effect of skin packaging on this parameter was evaluated for raw meat but also for cooked meat. Tenderness, juiciness, and the ability to hold liquid of raw meat when packed in skin conditions were also considered. Furthermore, odour and flavour were considered as sensorial parameters possibly affected by skin packaging. Finally, acceptability by consumer was also investigated. In the studies considered, results showed that skin packaging is advantageous in terms of maintenance of meat quality and for prolonging shelf-life, improving the stability of the products.

This study investigated the effect of moderate consumption of horse meat on iron status, lipid profile and fatty acid composition of red blood cells in healthy male volunteers. Fifty-two subjects were randomly assigned to two groups of 26 subjects each: a test group consuming two portions of 175 g/week of horse meat, and a control group that abstained from eating horse meat during the 90 days trial. Before and after 90 days, blood samples were collected for analysis. Horse meat consumption significantly (p ≤ 0.05) reduced serum levels of total and low-density lipoprotein cholesterol ( - 6.2% and - 9.1%, respectively) and transferrin ( - 4.6%). Total n - 3, long chain polyunsaturated fatty acids n - 3 and docosahexeanoic acid content in erythrocytes increased (p ≤ 0.05) by about 7.8%, 8% and 11%, respectively. In conclusion, the regular consumption of horse meat may contribute to the dietary intake of n - 3 polyunsaturated fatty acids and may improve lipid profile and iron status in healthy subjects.

Animal agriculture has exponentially grown in recent decades in response to the rise in global demand for meat, even in countries like Italy that traditionally eat a Mediterranean, plant-based diet. Globalization related dietary changes are contributing to the epidemic of non-communicable diseases and to the global climate crisis, and are associated with huge carbon and water footprints. The objective of the study is to assess inequalities in health impacts and in attributable greenhouse gases-GHG emissions in Italy by hypothesizing different scenarios of reduction in red and processed meat consumption towards healthier consumption patterns more compliant with the recommendations of the Mediterranean food pyramid. We used demographic and food consumption patterns from national surveys and risk relationships between meat intake and cardiovascular and colorectal cancer mortality from IARC and other meta-analyses. From the baseline data (year 2005-2006, average 406 gr/week beef and 245 gr/week processed meat), we considered hypothetical meat reduction scenarios according to international dietary guidelines such as the Mediterranean pyramid targets. For each geographical area (Northwest, Northeast, Centre, and South) and gender, we calculated the number of avoidable deaths from colorectal cancer, and cardiovascular disease among the adult population. Moreover, years of life gained by the adult population from 2012 to 2030 and changes in life expectancy of the 2012 birth cohort were quantified using gender-specific life tables. GHG emission reductions under Mediterranean scenario were estimated only for beef by applying the Global Warming Potential (GWP) coefficient to total consumption and to a low carbon food substitution in adult diet. The deaths avoidable (as percentage change compared to baseline) according to the three reduction scenarios for beef consumption were between 2.3% and 4.5% for colorectal cancer, and between 2.1% and 4.0% for cardiovascular disease

Human Nipah virus (NiV) infection in Bangladesh is a fatal disease that can be transmitted from bats to humans who drink contaminated raw date palm sap collected overnight during the cold season. Our study aimed to understand date palm sap consumption habits of rural residents and factors associated with consumption. In November-December 2012 the field team interviewed adult respondents from randomly selected villages from Rajbari and Kushtia Districts in Bangladesh. We calculated the proportion of people who consumed raw sap and had heard about a disease from raw sap consumption. We assessed the factors associated with raw sap consumption by calculating prevalence ratios (PR) adjusted for village level clustering effects. Among the 1,777 respondents interviewed, half (50%) reported drinking raw sap during the previous sap collection season and 37% consumed raw sap at least once per month. Few respondents (5%) heard about NiV. Thirty-seven percent of respondents reported hearing about a disease transmitted through raw sap consumption, inclusive of a 10% who related it with milder illness like diarrhea, vomiting or indigestion rather than NiV. Respondents who harvested date palm trees in their household were more likely to drink sap than those who did not own date palm trees (79% vs. 65% PR 1.2, 95% CI 1.1-1.3, psap was available, respondents who heard about a disease from raw sap consumption were just as likely to drink it as those who did not hear about a disease (69% vs. 67%, PR 1.0, 95% CI 0.9-1.1, p = 0.512). Respondents' knowledge of NiV was low. They might not have properly understood the risk of NiV, and were likely to drink sap when it was available. Implementing strategies to increase awareness about the risks of NiV and protect sap from bats might reduce the risk of NiV transmission.

Advancements in meat packaging.

Packaging of meat provides the same or similar benefits for raw chilled and processed meats as other types of food packaging. Although air-permeable packaging is most prevalent for raw chilled red meat, vacuum and modified atmosphere packaging offer longer shelf life. The major advancements in meat packaging have been in the widely used plastic polymers while biobased materials and their integration into composite packaging are receiving much attention for functionality and sustainability. At this time, active and intelligent packaging are not widely used for antioxidant, antimicrobial, and other functions to stabilize and enhance meat properties although many options are being developed and investigated. The advances being made in nanotechnology will be incorporated into food packaging and presumably into meat packaging when appropriate and useful. Intelligent packaging using sensors for transmission of desired information and prompting of subsequent changes in packaging materials, environments or the products to maintain safety and quality are still in developmental stages.

Full Text Available Market segmentation divides the market into small groups of consumers who share similar characteristics. As all consumers within the same group have a common profile, marketing strategies can be adapted to target a specific type of consumer. Owing to the rapid changes in today’s society, consumer lifestyle has become the ideal criterion for market segmentation. In this study, we employed the food-related lifestyle model, which scholars have shown to be suitable and valid in several countries. Using data from a survey (with 3.53% error, we segmented the Spanish food market based on consumers’ food-related lifestyles. For each segment, we identified the consumer profile and analysed consumers’ consumption of rabbit meat. Factor analysis and cluster analysis yielded 4 segments: (i ‘Unconcerned’ (36.8% of the sample mainly consists of male consumers. Consumers in this segment value neither the freshness nor the price/quality ratio of their food items and consume rabbit meat rarely (39.4% or sporadically (29.3%. (ii ‘Cooks’ (18.4% predominantly consists of middle-aged women. Consumers in this segment are highly demanding and critical of the quality of food products. They like cooking and are regular consumers of rabbit meat (40.6%. (iii ‘Out-of-home consumers and convenience shoppers’ (28.6% mostly consists of consumers aged between 25 and 34 y old and contains a large proportion of upper-class consumers. Consumers in this segment prefer to eat out and consume convenience products. This segment has the second highest percentage of regular consumers of rabbit meat (36.9%. The segment also has the second highest percentage of consumers who rarely or never eat rabbit meat (43.9%. (iv ‘Rational purchaser with little interest in cooking’ (16.2% has the highest proportion of consumers aged 55 to 74 y old. Consumers in this segment have the least interest in cooking, the most interest in the purchasing process, and the lowest

Food flavor appreciation is one of the first signals along with food appearance and texture encountered by consumers during eating of food. Also, it is well known that flavor can strongly influence consumer's acceptability judgment. The increase in the consumption of snail meat across the world calls for the need to research into the aroma compounds responsible for the distinctive aroma notes of processed snail meat. The odorants responsible for the unique aroma notes in thermally processed giant African snail meats were evaluated by means of aroma extract dilution analysis (AEDA), gas chromatography-olfactometry (GC-O) and odor activity values (OAVs) respectively. Results revealed significant differences in the aroma profiles of the raw and thermally processed snail meats. Whilst the aroma profile of the raw snail meat was dominated with the floral-like β-ionone and β-iso-methyl ionone, sweaty/cheesy-like butanoic acid, and the mushroom-like 1-octen-3-one, the boiled and fried samples were dominated with the thermally generated odorants like 2-methylpyrazine, 2,5-dimethylpyrazine, 2-acetylthiazole and 2-acetylpyridine. Finally, results have shown that sotolon, 2-acetyl-1-pyrroline, 2-furanmethanethiol, 2-methylbutanal, 1-octen-3-one, octanal, furanone, 2-methoxyphenol, 2-acetylpyridine, 2-acetylthiazole, and 2-methylpyrazine contributed to the overall aroma of the thermally processed snail meat.

Digestion of red and processed meat has been linked to the formation of genotoxic N-nitroso compounds (NOCs) and lipid peroxidation products (LPOs) in the gut. In this study, rats were fed a meat based diet to compare the possible genotoxic effects of red vs. white meat, and the interfering role of dietary fat. To this purpose, liver, duodenum and colon DNA adductomes were analyzed with UHPLC-HRMS. The results demonstrate that the consumed meat type alters the DNA adductome; the levels of 22 different DNA adduct types significantly increased upon the consumption of beef (compared to chicken) and/or lard supplemented beef or chicken. Furthermore, the chemical constitution of the retrieved DNA adducts hint at a direct link with an increase in NOCs and LPOs upon red (and processed) meat digestion, supporting the current hypotheses on the causal link between red and processed meat consumption and the development of colorectal cancer.

Salmonellosis is one of the major food-borne diseases in many countries. This study was carried out to determine the occurrence of Salmonella spp., Salmonella Enteritidis, and Salmonella Typhimurium in raw chicken meat from wet markets and hypermarkets in Selangor, as well as to determine the antibiotic susceptibility profile of S. Enteritidis and S. Typhimurium. The most probable number (MPN) in combination with multiplex polymerase chain reaction (mPCR) method was used to quantify the Salmonella spp., S. Enteritidis, and S. Typhimurium in the samples. The occurrence of Salmonella spp., S. Enteritidis, and S. Typhimurium in 120 chicken meat samples were 20.80%, 6.70%, and 2.50%, respectively with estimated quantity varying from retail chicken meat could be a source of multiple antimicrobial-resistance Salmonella and may constitute a public health concern in Malaysia. © 2016 Poultry Science Association Inc.

Full Text Available Background: These findings from several observational studies, investigated the association between red meat consumption and gliomas, were inconsistent. We conducted a systematic review and meta-analysis of observational studies to summarize available date on the relation between meat intake and risk of glioma. Materials and Methods: A systematic literature search of relevant reports published until May 2014 of the PubMed/Medline, ISI Web of Knowledge, Excerpta Medica database, Ovid database, Google Scholar, and Scopus databases was conducted. From 723 articles yielded in the preliminary literature search, data from eighteen publications (14 case-control, three cohort, and one nested case-control study on unprocessed red meat, processed meat, and/or total red meat consumption in relation to glioma in adults were included in the analysis. Quality assessment of studies was performed. Random effects model was used to conduct the meta-analysis. Results: We found a positive significant association between unprocessed red meat intake and risk of glioma (relative risk [RR] = 1.30; 95% confidence interval [CI]: 1.08-1.58 after excluding three studies with uncertain type of brain cancer. This analysis included only one cohort study which revealed no relation between unprocessed red meat intake and glioma (RR = 1.75; 95% CI: 0.35-8.77. Consumption of processed meats was not related to increased risk of glioma in population-based case-control studies (RR = 1.26; 95% CI: 1.05-1.51 and reduced risk in hospital-based case-controls (RR = 0.79; 95% CI: 0.65-0.97. No significant association was seen between processed red meat intake and risk of glioma in cohort studies (RR: 1.08; 95% CI: 0.84-1.37. Total red meat consumption was not associated with risk of adult glioma in case-control or cohort studies. Conclusion: In this meta-analysis of 18 observational studies, we found a modest positive association between unprocessed red meat intake and risk of gliomas

This study evaluated omega-3 intramuscular fatty acids in the longissimus thoracis et lumborum of commercially prepared Australian lamb loin chops. Meats, denuded of external fats were cooked by means of conductive dry-heat using a fry grilling hot plate, to a core temperature of 70°C. An untrained consumer panel assessed meat appearance, aroma, tenderness, juiciness, taste and overall liking. Results showed no compositional alterations (P>0.05) to omega-3 fatty acids due to cooking treatment, whereas on absolute terms (mg/100g muscle) omega-3 fatty acids significantly (Pcooked meat at 32.8±2.3mg/100g muscle exceeded the minimum 30mg/100g per edible portion required for the defined Australian classification as 'source' long-chain (≥C 20 ) omega-3 for cooked lamb. A 3.4% intramuscular fat content in the initial raw meat was sufficient to maintain acceptable overall sensory eating quality. Results endorse the application of this cooking method to enable delivery of health beneficial long-chain omega-3 fatty acids of commercially prepared Australian lamb loin chops to consumers without impediments to sensory eating properties.

This study reports on current meat consumption in the UK and the factors that are percieved by the subjects to be influential in their choice of diet. A random sample of individuals from the population (n-1018) were questioned on their consumption and attitudes towards meat by a postal survey. The study revealed that 28·3% of the population considered themselves to be reducing meat consumption; attitudes found to be determinant in changes in the consumption of meat were healthiness, taste and concerns over additives. Hypothetical future events were found to affect people's estimated meat-eating. Knowledge of meat-related information was investigated with specific reference to the respondents' trust in the various sources used; food package labels were found to be an influential source of meat-related information.

To examine the association of red meat and whole-grain bread consumption with plasma levels of biomarkers related to glucose metabolism, oxidative stress, inflammation and obesity. Our cross-sectional study was based on 2,198 men and women who were selected as a sub-cohort for an investigation of biological predictors of diabetes and cardiovascular diseases from the European Prospective Investigation into Cancer and Nutrition-Potsdam study. Circulating levels of glycated hemoglobin, adiponectin, hs-CRP, gamma-glutamyltransferase, alanine-aminotransferase, fetuin-A, HDL-cholesterol and triglycerides were measured from random blood samples. Diet and lifestyle data were assessed by questionnaires, and anthropometric data were measured. After multivariable adjustment, higher consumption of whole-grain bread was significantly (P trend consumption of red meat was significantly associated with higher levels of GGT and hs-CRP when adjusted for potential confounding factors related to lifestyle and diet. Further adjustment for body mass index and waist circumference attenuated the association between red meat and hs-CRP (P = 0.19). The results of this study suggest that high consumption of whole-grain bread is related to lower levels of GGT, ALT and hs-CRP, whereas high consumption of red meat is associated with higher circulating levels of GGT and hs-CRP.

Full Text Available This study was conducted to observe antioxidant enzyme activity, iron content and lipid oxidation of Korean native chickens and other poultry. The breast and thigh meat of three Korean native chicken breeds including Woorimatdak, Hyunin black and Yeonsan ogye, and three commercial poultry breeds including the broiler, White Leghorn and Pekin duck (Anasplatyrhyncos domesticus were studied. The analyses of the antioxidant enzymes activity, iron content and lipid oxidation were performed in raw and cooked samples. The activity of catalase (CAT in the thigh meat was higher than that of the breast meat of three Korean native chickens and the broiler, respectively. The activity of glutathione peroxidase (GPx in the uncooked thigh meat of three Korean native chickens was higher than that of the breasts. The breast meat of Woorimatdak and Pekin duck had higher superoxide dismutase (SOD activity than the others, while only the thigh meat of Pekin duck had the highest activity. Cooking inactivated CAT and decreased the activity of GPx and SOD. The thigh meat of Woorimatdak, White Leghorn, Yeonsan ogye and Hyunin black contained more total iron than the breast meat of those breeds. The heme-iron lost during cooking ranged from 3.2% to 14.8%. It is noted that the thigh meat had higher thiobarbituric acid reactive substances values than the breast in all chicken breeds. Though Woorimatdak showed higher antioxidant enzyme activity and lower released-iron percentage among Korean native chickens, no differences were found on lipid oxidation. We confirm that the dark meat of poultry exhibited higher antioxidant enzyme activity and contained more iron than the white meat.

Fraudulent mislabelling of processed meat products on a global scale that cannot be detected using conventional techniques necessitates sensitive, robust and accurate methods of meat authentication to ensure food safety and public health. In the present study, we developed an in-gel (two-dimensional gel electrophoresis, 2DE) and OFFGEL-based proteomic method for authenticating raw and cooked water buffalo (Bubalus bubalis), sheep (Ovis aries) and goat (Caprus hircus) meat and their mixes. The matrix-assisted liquid desorption/ionization time-of-flight mass spectrometric analysis of proteins separated using 2DE or OFFGEL electrophoresis delineated species-specific peptide biomarkers derived from myosin light chain 1 and 2 (MLC1 and MLC2) of buffalo-sheep-goat meat mix in definite proportions at 98:1:1, 99:0.5:0.5 and 99.8:0.1:0.1 that were found stable to resist thermal processing. In-gel and OFFGEL-based proteomic approaches are efficient in authenticating meat mixes spiked at minimum 1.0% and 0.1% levels, respectively, in triple meat mix for both raw and cooked samples. The study demonstrated that authentication of meat from a complex mix of three closely related species requires identification of more than one species-specific peptide due to close similarity between their amino acid sequences. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Gomółka-Pawlicka, M; Uradziński, J; Wiszniewska, A

2004-01-01

The present study was aimed at determining the influence of 15 strains of lactic acid bacteria on the growth of 2 Staphylococcus aureus strains in vitro as well as in meat and raw sausages. The investigations were performed within the framework of three alternate stages which differed in respect to the products studied, the number of Lactobacillus sp. strains and, partly, methodological approach. The study also considered water activity (a(w)) and pH of the products investigated. The results obtained are demonstrated in 5 diagrams. It was found that among 15 strains of Lactobacillus aureus investigated only one strain, Lactobacillus helveticus T 78, showed antagonistic effect on studied strains of Staphylococcus aureus both in vitro as well as in meat and raw sausages. Five other strains of Lactobacillus spp. displayed the antagonistic effect in vitro only. The temperature and incubation time of sausages, but also the type of sausage stuffing were found to have a distinct or slight influence, respectively, on the antagonistic interaction between the bacteria. However, this phenomenon was affected by neither a(w) nor pH.

Rising consumption of meat and milk in developing countries has created a new food revolution.

Science.gov (United States)

Delgado, Christopher L

2003-11-01

People in developing countries currently consume on average one-third the meat and one-quarter of the milk products per capita compared to the richer North, but this is changing rapidly. The amount of meat consumed in developing countries over the past has grown three times as much as it did in the developed countries. The Livestock Revolution is primarily driven by demand. Poor people everywhere are eating more animal products as their incomes rise above poverty level and as they become urbanized. By 2020, the share of developing countries in total world meat consumption will expand from 52% currently to 63%. By 2020, developing countries will consume 107 million metric tons (mmt) more meat and 177 mmt more milk than they did in 1996/1998, dwarfing developed-country increases of 19 mmt for meat and 32 mmt for milk. The projected increase in livestock production will require annual feed consumption of cereals to rise by nearly 300 mmt by 2020. Nonetheless, the inflation-adjusted prices of livestock and feed commodities are expected to fall marginally by 2020, compared to precipitous declines in the past 20 y. Structural change in the diets of billions of people is a primal force not easily reversed by governments. The incomes and nutrition of millions of rural poor in developing countries are improving. Yet in many cases these dietary changes also create serious environmental and health problems that require active policy involvement to prevent irreversible consequences.

The role of meat in squamous cell carcinoma of the esophagus (ESCC) has been considered conflictive. For this reason, we decided to conduct a case-control study on meat consumption and ESCC. Data included 234 newly diagnosed and microscopically examined ESCC and 2,020 controls with conditions not related to tobacco smoking nor alcohol drinking and without changes in their diets. We studied total meat, red meat, beef, lamb, processed meat, poultry, fish, total white meat, liver, fried meat, barbecued meat, boiled meat, heterocyclic amines, nitrosodimethylamine, and benzo[a]pyrene in relation with the risk of ESCC. Red meat, lamb, and boiled meat were directly associated with the risk of ESCC, whereas total white meat, poultry, fish, and liver were mainly protective against this malignancy.

Rababah, Taha

The purpose of this study included: preparing plant extracts and evaluating these extracts for total phenolics and antioxidant activities (AA); infusing extract/combination that demonstrates superior AA into chicken breast and irradiating at 3.0 kGy; evaluating the physicochemical properties of irradiated and non-irradiated raw and cooked chicken breast at 5°C for 12 days and -20°C for 9 months; and selecting the extracts that demonstrated desirable AA, infusing these extracts into chicken breast and evaluating head-space volatiles, and conducting sensory evaluation. The total phenolic content and AA of the plant extracts ranged from 24.8 to 92.5 mg/g dry material (conjugated diene of methyl linoleate) and 3.4 to 86.3%, respectively. The AA of plant extracts using oxidative stability instrument were 4.6 to 10.2 h (Induction time). Green tea and grape seed extracts had the highest AA within several plant extracts, and were selected to retard lipid oxidation in further studies. Fresh boneless and skinless chicken breast meats were vacuum infused with varying concentrations of antioxidants: Green tea and grape seed extracts alone/in combination and tert-butylhydroquinone. The results showed that irradiation had no significant effect on pH, water holding capacity, but increased the redness and carbonyls in raw meats (p extracts into meats increased lightness and decreased redness as well as hardness and shear force. Irradiation increased TBARS, hexanal, and pentanal values in raw and cooked meats. Addition of plant extracts decreased the amount of TBARS, hexanal, pentanal, and carbonyl values. Similar results were observed when the samples were stored at -20°C for 9 months. Descriptive sensory flavor results showed that irradiation did not affect the flavor attributes. Consumer, descriptive, and instrumental results showed that irradiation increased toughness, green tea improved the meat color, and the panel indicated that irradiation decreased the tenderness of the

We examined the relationship between different patterns of meat and seafood consumption and plasma metabolic profiles in an Asian population. We selected 270 ethnic Chinese men and women from the Singapore Prospective Study Program based on their dietary habits assessed with a validated food frequency questionnaire. Participants were divided into four subgroups: high meat and high seafood ( n = 60), high meat and low seafood ( n = 64), low meat and high seafood ( n = 60), and low meat and low seafood ( n = 86) consumers. Plasma metabolites were measured using both targeted and untargeted mass spectroscopy-based analyses. A total of 42 metabolites differed significantly by dietary group. Higher concentrations of essential amino acids, polyunsaturated fatty acids, and d-glucose were found in high meat and/or seafood consumers as compared with the group with a low consumption of these animal foods. Red meat, poultry, fish, shellfish, soy products, and dairy were each correlated with at least one differential metabolite ( r = -0.308 to 0.448). Some observations, such as the correlation between fish and 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF), confirmed previous studies. Other observations, such as the correlation between shellfish and phosphatidylethanolamine (p36:4), were novel. We also observed significant correlations between plasma metabolites and clinical characteristics, such as CMPF with fasting blood glucose ( r = 0.401). These findings demonstrate a significant influence of meat and seafood consumption on metabolic profiles in the Asian population.

Full Text Available A 6-wk feeding study was conducted to evaluate the antioxidative potential, indices such as quality of the thigh meat and liver of broiler chickens fed with a dietary medicinal herb extract mixture (HEM, consisting: Iranian green tea, cinnamon, garlic and chicory at a ratio of 25:15:45:15. A total of 320, one-d-old Ross (male broiler chickens were used to investigate the effects of 0.0, 2.5, 5.0 and 7.5 g/kg HEM in the diet, on aforementioned factors. The HEM supplementation did not influence the composition of raw thigh meat except for the total phenols and crude ash (P<0.05. Furthermore, pH, water-holding capacity (WHC and acceptability of thigh meat were affecting by administration of HEM in diets (P<0.05. Meat flavor increased in the supplemented groups (P<0.05. According to our data, HEM supplementation decreased the amount of thiobarbituric acid reactive substance (TBARS in various times of storage and improved the liver lipid peroxides and superoxide dismutase (SOD activities at week 6 (P<0.05, but did not influence the catalase activity. Our results reveal that the addition of 7.5 g/kg or higher HEM in diet could be sufficient to increase the antioxidative activity and 2.5 g/kg for meat taste of broilers in maximum levels.

Background The seroepidemiology of Leptospira infection in workers occupationally exposed to raw meat has been poorly studied. This work aimed to determine the association between Leptospira exposure and the occupation of meat worker, and to determine the seroprevalence association with socio-demographic, work, clinical and behavioral characteristics of the meat workers studied. Methods We performed a case-control study in 124 meat workers and 124 age- and gender-matched control subjects in Durango City, Mexico. Sera of cases and controls were analyzed for anti-Leptospira IgG antibodies using a commercially available enzyme immunoassay. Data of meat workers were obtained with the aid of a questionnaire. The association of Leptospira exposure with the characteristics of meat workers was analyzed by bivariate and multivariate analyses. Results Anti-Leptospira IgG antibodies were found in 22 (17.7%) of 124 meat workers and in eight (6.5%) of 124 controls (OR = 3.12; 95% CI: 1.33 - 7.33; P = 0.006). Seroprevalence of Leptospira infection was similar between male butchers (17.6%) and female butchers (18.2%) (P = 1.00). Multivariate analysis of socio-demographic, work and behavioral variables showed that Leptospira exposure was associated with duration in the activity, rural residence, and consumption of snake meat and unwashed raw fruits. Conclusions This is the first case-control study of the association of Leptospira exposure with the occupation of meat worker. Results indicate that meat workers represent a risk group for Leptospira exposure. Risk factors for Leptospira exposure found in this study may help in the design of optimal preventive measures against Leptospira infection. PMID:26858797

Sociological aspects of meat in meals

Health professionals and environmental experts advocate reduced consumption of meat in industrialized regions. On this background, and in light of a number of sociological studies of food practices and meal formats among consumers, this paper examines some aspects of the cultural entrenchment...... and vulnerability of meat consumption. Tacit meanings of meat products are seen as arising from the human tendency to rank and grade objects relative to each other, a process that is intrinsic to consumption practices. Examples of the ways in which gradient meanings of meat products are entrenched in food practices...... and of ways in which this consumption is vulnerable to change, are presented. On this basis, the likelihood that current levels of meat consumption in industrialized societies will remain relatively stable or tend to decrease are briefly discussed....

Survey of the parasite Toxoplasma gondii in human consumed ovine meat in Tunis City.

Directory of Open Access Journals (Sweden)

Sonia Boughattas

Full Text Available Toxoplasmosis has been recognized as parasitic zoonosis with the highest human incidence. The human infection by the parasite can lead to severe clinical manifestations in congenital toxoplasmosis and immunocompromised patients. Contamination occurs mainly by foodborne ways especially consumption of raw or undercooked meat. In contrast to other foodborne infections, toxoplasmosis is a chronic infection which would make its economic and social impact much higher than even previously anticipated. Ovine meat was advanced as a major risk factor, so we investigated its parasite survey, under natural conditions. Serological MAT technique and touchdown PCR approaches were used for prevalence determination of the parasite in slaughtered sheep intended to human consumption in Tunis City. The genotyping was carried by SNPs analysis of SAG3 marker. Anti-Toxoplasma antibodies were present in 38.2% of young sheep and in 73.6% of adult sheep. Molecular detection revealed the contamination of 50% of ewes' tissue. Sequencing and SNPs analysis enabled unambiguous typing of meat isolates and revealed the presence of mixed strains as those previously identified from clinical samples in the same area. Our findings conclude that slaughtered sheep are highly infected, suggesting them as a major risk factor of Toxoplasma gondii transmission by meat consumption. Special aware should target consequently this factor when recommendations have to be established by the health care commanders.

To assess the association of red and white meat consumption with general and abdominal obesity among Iranian military families. In this cross-sectional study, 525 subjects with age range of 19-55 years belong to military families of Army of Islamic Republic of Iran were recruited during 2016. Dietary data were collected using semi-quantitative food-frequency questionnaire. A self-reported questionnaire was used to collect data on demographic characteristics and anthropometric measurements. General obesity was defined as body mass index ≥25 kg/m 2 and abdominal obesity as waist circumference ≥80 cm for women and ≥ 94 cm for men. Finally, we had complete data on 170 subjects for analysis. Mean age of subjects was 33.78 ± 6.48. We found a significant positive association between red meat consumption and abdominal obesity in fully adjusted model, so that subjects in the fourth quartile had 4.51 more odds to be abdominally obese compared with those in the first quartile of red meat consumption (OR 4.51, 95% CI 1.32-15.40). Such relationship was not seen for general obesity. In addition, white meat consumption was not associated with general and abdominal obesity either before or after adjustment for covariates. Red meat consumption was positively associated with abdominal obesity. No significant relationship was found between white meat consumption, and general and abdominal obesity. Therefore, further studies are needed to shed light our findings.

Rabbit meat processing: historical perspective to future directions

Full Text Available In past centuries, because rabbits are relatively small, animals slaughtered for consumption were generally eaten immediately. However, since a single rabbit would offer little more product than could be consumed at one sitting, little effort was devoted to developing preserved rabbit products (such as salted or dried meat, sausages, etc.. For this reason, although there is a rich history of recipes using rabbit meat in the Mediterranean area, there are few traditional further-processed products. Nowadays, even though the processing industry is pushing more and more towards the introduction of more attractive products (i.e. ready meals, ready-to-cook, etc. for consumers with little time for meal preparation, most rabbit meat worldwide is still sold as whole carcass or cut-up parts. This review analyses the main strength and weakness factors regarding the use of rabbit meat to manufacture further processed products. Bearing in mind these considerations, it then describes the more promising processing technologies for raw meat materials to obtain added-value products (marinated, formed, emulsified, coated, etc. by exploiting rabbit meat’s intrinsic characteristics, such as high protein/low fat content coupled with a balanced n-6 to n-3 PUFA ratio, low cholesterol and heme-iron content. Major trends in meat product formulation (modulation of lipid content and composition, use of novel antioxidants and salt reduction are also discussed by highlighting strategies to provide healthier meat products meeting current nutritional needs. Finally, major packaging solutions for rabbit meat and meat products (ordinary and modified atmosphere, vacuum are considered.

Specifity of Cultural Layers Filling and Dynamics of Meat Consumption in the City of Bolgar (based on the archaeozoological materials of CLXXIX excavation trench

Yavorskaya Lilia V.

2013-09-01

Full Text Available Reliable samplings of animal bones obtained through five chronological periods from CLXXIX excavation trench on the Bulgar fortified settlement site are examined in the article. The results have made it possible to reveal fluctuations in meat consumption characteristic of this part of the city between the pre-Mongol and the later Golden Horde periods. Throughout all the periods of the city history, beef had dominated meat consumption structure there. The role of other meat animal species underwent definite changes. In the pre-Mongol period, beef was supplemented with meat of small cattle and horses in the diet of the settled population of Bulgar; fish was apparently no less important. In the early Golden Horde period, mutton consumption increased, while the proportion of beef and horse-flesh decreased. By the later Golden Horde period, the share of mutton in meat consumption in this part of Bulgar had increased to reach 42 per cent as compared to 15 per cent in the pre-Mongol period. The surge in mutton consumption in Bulgar in the Golden Horde period apparently means a shift in economic strategies of Volga Bulgaria population and attests to the increasing role of the steppe nomadic population in the economic activity of the region.

Little is known about public knowledge of meat chicken production and how it influences attitudes to birds' welfare and consumer behaviour. We interviewed 506 members of the public in SE Queensland; Australia; to determine how knowledge of meat chicken production and slaughter links to attitudes and consumption. Knowledge was assessed from 15 questions and low scores were supported by respondents' self-assessed report of low knowledge levels and agreement that their knowledge was insufficient to form an opinion about which chicken products to purchase. Older respondents and single people without children were most knowledgeable. There was uncertainty about whether chicken welfare was adequate, particularly in those with little knowledge. There was also evidence that a lack of empathy towards chickens related to lack of knowledge, since those that thought it acceptable that some birds are inadequately stunned at slaughter had low knowledge scores. More knowledgeable respondents ate chicken more frequently and were less likely to buy products with accredited labelling. Approximately half of the respondents thought the welfare of the chicken was more important than the cost. It is concluded that the public's knowledge has an important connection to their attitudes and consumption of chicken.

Food specimens were analyzed in order to research Enterococcus spp.: 636 samples of raw meat (227 beef, 238 poultry, and 171 pork), 278 samples of cheese (110 fresh soft cheese and 168 mozzarella cheese), 214 samples of ready-to-eat salads, and 187 samples of ham. 312 strains of Enterococcus spp samples were isolated, then identified and submitted to susceptibility tests against 11 antimicrobial agents. The predominant species were Enterococcus faecalis in raw meat and Enterococcus faecium in retail products. Low percentages of microorganisms were resistant to vancomycin (3.53%), teicoplanin (2.24%), linezolid (0.32%), and amoxicillin in combination with clavulanic acid (0.32%). A high percentage of resistance was noted in E. faecalis at high level gentamicin (21.9%) and tetracycline (60.6%). In general, strains of E. faecalis were more resistant than E. faecium. Enterococci should be considered not only potential pathogens, but also a reservoir of genes encoding antibiotic resistance which can be transferred to other microorganisms. Continuous monitoring of their incidence and emerging resistance is important in order to identify foods which potentially represent a real risk to the population, and to ensure effective treatment of human enterococcal infections.

Species identification and authentication in meat products are important subjects for ensuring the health of consumers. The multiplex-PCR amplification and species- specific primer set were used for the identification of horse, donkey, pig and other ruminants in raw and processed meat products. Oligonucleotid primers were designed and patented for amplification of species-specific mitochondrial DNA sequences of each species and samples were prepared from binary meat mixtures. The results showed that meat species were accurately determined in all combinations by multiplex-PCR, and the sensitivity of this method was 0.001 ng, rendering this technique open to and suitable for use in industrial meat products. It is concluded that more fraud is seen in lower percentage industrial meat products than in higher percentage ones. There was also more fraud found in processed products than in raw ones. This rapid and useful test is recommended for quality control firms for applying more rigorous controls over industrial meat products, for the benefit of target consumers.

Goat Meat (chevon) has been used as a source of protein and its demand for consumption is increasing yearly in Malaysia. The objective of the research was to determine proximate composition namely moisture, protein, fat and ash level in chevon from different type of breed i.e. Boer and Katjang. The goat breed proximate analyses were compared with sheep meat (mutton). The results for goat breeds were showing that the percentage of moisture, fat, protein and ash were of 73.06 - 74.99, 2.76 - 2.94, 20.81 - 22.47 and 0.97 - 1.21 respectively. Meanwhile the concentration of moisture, fat, protein and ash for mutton were 73.52, 5.06, 22.50 and 1.17 respectively. The pilot study on perception survey indicated that the highest respondent percentage on consumption of chevon was once in a month. Based on the survey, Boer was the most known breed compared to the other breed. Majority of respondents reported that chevon was fairly expensive meat but easier to obtain in the survey area.

Campylobacter causes acute gastroenteritis in people worldwide and is frequently isolated from food, animals and the environment. The disease is predominately food-borne but many routes of transmission and sources of infection have been described, including contact with pets. The prevalence of Campylobacter spp. in dogs and cats varies widely, and data on New Zealand pets are limited. This study aimed to investigate the prevalence of Campylobacter spp. in dogs, cats and retail raw meat pet food products in New Zealand and to characterize Campylobacter jejuni isolates using multilocus sequence typing (MLST). Ninety dogs and 110 cats examined at the Massey University Veterinary Teaching Hospital for elective procedures, and fifty locally purchased retail raw meat pet diets were sampled. Two culture protocols combining Bolton broth enrichment and mCCDA and CAT agars in a microaerobic atmosphere at 42°C and 37°C with species identification using PCR were performed. The prevalence of Campylobacter spp., C. jejuni, Campylobacter upsaliensis and Campylobacter helveticus was 36%, 13%, 23% and 1% in dogs and 16%, 5%, 5% and 7% in cats, respectively. One dog had Campylobacter lari confirmed, and three dogs and one cat had multiple Campylobacter spp. detected. Significantly more animals tested positive using CAT than mCCDA agar (P dogs, whereas attendance for dental treatment was a risk factor for cats. Campylobacter spp. were isolated from 28%, C. jejuni 22%, C. lari 6% and Campylobacter coli 6% of food samples. Six isolates positive by Campylobacter genus PCR were identified as Arcobacter butzleri. Poultry meat was more likely to be positive than non-poultry meat (P = 0.006). Of the 13 C. jejuni pet isolates with full MLST profiles, eight were of different sequence types (ST) and all nine food isolates were of different STs. © 2016 Blackwell Verlag GmbH.

Full Text Available Spent ducks produce nutritive meat; however the meat possesses undesirable characteristics such as strong odor and tough. Hence, appropriate yet simple processing technologies need to be developed in order to maximize the use of duck meat. The experiment was conducted to evaluate functional characteristics of spent duck meat as raw material for the production of emulsion-type meat products, such as nugget and sausage. Chilled carcasses of 96 spent ducks were deboned manually, then mixed thoroughly and ground using a 5 mm diameter grinding plate. The ground meat was divided into 4 batches (group of treatments; one batch was treated with iced tap water (M1, one batch with 0.1% NaCl solution (M2, one batch with 0.5% NaHCO3 solution (M3, and one batch was left as is as control (M4. Variables measured were water holding capacity (WHC, pH, emulsion capacity and stability of the meat; and firmness and tenderness of the meat gel. Results showed that M1 meat has significantly higher WHC (less percentage of free water than control (M4, whereas M2 and M3 meat has similar WHC to control. Processing caused the ground duck meat to have significantly higher pH than control. The highest meat pH was observed in M3, followed by M2, M1 and control. Processing duck meat with iced tap water, NaCl or NaHCO3 produced significantly more tender meat gel compared to untreated meat (as is. Tenderness of meat gel of M3 was the most tender followed by M2 and M1. Similar results for meat gel firmness were observed. No significant differences were observed in term of emulsion capacity (expressed as ml oil/gr protein and ml oil/gr fresh meat, emulsion stability (expressed as ml oil and total liquid released per 100 gr emulsion, and cooking recovery (%. The study reported in this paper offers simple processing technologies to improve functional characteristics of spent duck meat to be use as raw material for the production of emulsion type meat products.

2016-01-01

Full Text Available In this paper, the results of the experimental research on developing the technology of a protein complex based on the meat-bone paste and protein-fat-blood emulsion are shown. The technological scheme of meat-bone paste production on the basis of complex grinding meat-bone raw material to bone particle size of 100 ∙10–6 m and further processing of bone particles using reagent, cheese whey, with pH 4,3 is presented. When studying the nutritive and biological value of the protein complex, it was established that the protein complex consisting of the food component from bone and protein-fat-blood emulsion could be used instead of the basic raw material in meat product production. The comparative analysis of the nutritive value of the protein complex and horse meat demonstrated the following results: the amino acid composition of the protein complex showed a balance of the essential amino acids and the high content of the essential amino acids which limit the biological value: lysine, leucine and threonine. The high content of polyunsaturated fatty acids was observed, which justified the biological value of the protein complex.

Spleen extract biologically active substances were used as immunomodulators and anti-stressors during pre-slaughter period. Biologically active substances influence on putrescin, spermine and spermidine content in broiler chicken blood before slaughter and on some non-specific resistance indices in people was determined after consumption of broiler chicken meat. Two groups of broiler chickens at one month age were formed for the study. The spleen extract obtained with ultrasound application (I research group served as biologically active substances was added to the feed of broiler chickens in pre-slaughter period (five days before slaughter. Blood polyamines such as putrescin, spermine and spermidine were determined by the method of High-performance liquid chromatography (HPLC on the liquid chromatograph Agilent 1200 (USA. The second experiment was conducted on 10 people. We recruited 10 healthy male medical students (20 years old, on average after the National Medical license examination. Spleen extract polyamines as immunomodulators and anti-stressors have the most effective influence on total quantity of polyamines in broiler chicken blood. As a result of research, it is found that aerosol introduction of spleen extract into broiler chicken feed reliably increases total quantity of polyamines by 39% and, in particular, spermidine concentration by 34%, and spermine by 40% compared with broiler chickens of the control group. Some non-specific body resistance indices in men blood upon consumption of broiler chicken meat varied within the physiological norm. The neutrophils stimulation index increased in men blood (+0,82 after consumption of meat of broiler chickens to which spleen extract as immunomodulator and anti-stressor was

The bacterial genera Listeria and Staphylococcus have been frequently isolated from food products and are responsible for a number of animal and human diseases. The aim of the study was to simultaneously isolate and characterize L. monocytogenes and Staphylococcus species from 300 samples of raw meat and meat products, to determine the susceptibility of the organisms to commonly used antimicrobial agents and to determine the presence of haemolysin A (hyl) virulence gene in L. monocytogenes and staphylococcal cassette chromosome mecA (SCCmec) gene in the Staph. aureus isolates using PCR. Of the 85 Listeria isolates tested, 12 L. monocytogenes were identified and tested for their sensitivity to 14 antimicrobial agents. All the 12 isolates (100%) were resistant to nine antimicrobial agents, but however sensitive to gentamicin. Only one isolate was found to harbour the hylA gene. Twenty-nine isolates were confirmed as Staph. aureus by the Microbact 12S identification system and were all presumptively identified as methicillin-resistant Staph. aureus species using oxacillin-resistant Staph. aureus basal medium (ORSAB). The 29 Staph. aureus isolates were tested for their sensitivity to 16 antimicrobial agents, and 11 were resistant to methicillin. None of the 11 Staph. aureus isolates harboured the methicillin resistance, mecA gene. Listeria monocytogenes and Staphylococcus aureus are important agents of foodborne diseases. Occurrence of these infectious agents was established in meat and meat products in Zaria, Nigeria. Majority of isolates obtained from this study, displayed multidrug resistance to commonly used antimicrobial agents, including methicillin resistance among the Staph. aureus isolates. The potential virulence of L. monocytogenes found in ready-to-eat food was documented by the carriage of hly A gene by one of the isolates. A different mechanism of methicillin resistance or different homologue of mec A gene may be circulating among Nigerian

Recent theorizing suggests that the 4Ns - that is, the belief that eating meat is natural, normal, necessary, and nice - are common rationalizations people use to defend their choice of eating meat. However, such theorizing has yet to be subjected to empirical testing. Six studies were conducted on the 4Ns. Studies 1a and 1b demonstrated that the 4N classification captures the vast majority (83%-91%) of justifications people naturally offer in defense of eating meat. In Study 2, individuals who endorsed the 4Ns tended also to objectify (dementalize) animals and included fewer animals in their circle of moral concern, and this was true independent of social dominance orientation. Subsequent studies (Studies 3-5) showed that individuals who endorsed the 4Ns tend not to be motivated by ethical concerns when making food choices, are less involved in animal-welfare advocacy, less driven to restrict animal products from their diet, less proud of their animal-product decisions, tend to endorse Speciesist attitudes, tend to consume meat and animal products more frequently, and are highly committed to eating meat. Furthermore, omnivores who strongly endorsed the 4Ns tended to experience less guilt about their animal-product decisions, highlighting the guilt-alleviating function of the 4Ns.

The Inuit population of the Arctic has always been at risk of acquiring trichinellosis and severe outbreaks have been recorded in Alaska and Canada. In West Greenland, a number of large outbreaks took place during the 1940s and 1950s; they involved total 420 cases including 37 deaths. Since then only sporadic cases have been reported. Here, we describe an outbreak of infection with Trichinella spp. after consumption of infected meat presumably from walrus or polar bear caught in western Greenland. Six persons who had eaten of the walrus and polar bear meat were two males and four females, age range 6--47 years. Using ELISA and Western blot analysis (Trichinella-specific IgG antibodies against excreted/secreted antigen and synthetic tyvelose antigen, respectively) four of these persons were found to be sero-positive for Trichinella antibodies, with three of these having clinical symptoms compatible with trichinellosis. On re-test, 12--14 months later one of the two sero-negative persons had sero-converted, probably due to a new, unrelated infection. This study demonstrates that acquiring Trichinella from the consumption of marine mammals remains a possibility in Greenland, and that cases may go undetected. Trichinellosis in Greenland can be prevented by the implementation of public health measures.

Full Text Available Biomass is doubtless a very significant source of renewable energy being worldwide abundant with high energy potential. This paper deals with assessment energy consumption at especially grinding and briquetting processes, which should result in essential economy of energy at solid biofuel production. Various types of raw materials were used at the experiment such as hemp (Cannabis sativa L. biomass, two species of Miscanthus (Miscanthus sinensis, Miscanthus x gigantheus and apple wood biomass. These materials were dried, grinded and pressed by piston press having pressing chamber diameter of 65 mm. Materials were grinded into three fractions (4 mm, 8 mm and 12 mm. Material throughput (kg.h-1 and energy consumption (kWh.t-1 were registered. As to results: the highest throughput at both grinding cases as well as briquetting was found at apple wood biomass; however the energy consumption during briquetting of apple wood was relatively high. The worst results concerning throughput and energy consumption (especially at briquetting were found at hemp biomass. Nevertheless, briquettes made of hemp had the best mechanical durability. Both Miscunthus species (herbaceous biomass have very similar parameters and showed quite good relation between throughput and energy consumption at the used machines.

Ready-to-eat emulsion-type buffalo meat sausages were developed by using a combination of 80% meat components with 20% pork back fat. The meat components were constituted of 70 parts buffalo skeletal meat and 30 parts offal meat (rumen meat and heart meat in equal proportions). The emulsion stability, cooking losses of emulsions and sausages, composition of cooked sausages, eating quality of sausages and the microscopic characteristics of the raw emulsion and cooked sausages were studied. The light microscope micrograph of the raw emulsion showed uniformly well distributed fat globules embedded in a dense protein gel. The cooked emulsion also showed uniformly sized fat globules well distributed in a fine, compact, coagulated protein gel, which retained their original spherical shape. Good quality emulsion-type sausages could be produced having a high emulsion stability (0·87 ± 0·07 ml fat release/100 g emulsion); a low emulsion cooking loss (9·60 ± 0·60%) and a low sausage cooking loss (8·83 ± 0·48%). The overall acceptability of sausages was also high. Copyright © 1990. Published by Elsevier Ltd.

A rapid increase in the economy, population, industrialization, and urbanization of Asian countries has driven the fast development of their meat industries over recent decades. This consistent increase in meat production and consumption in Asia has been the major cause for the development of the global meat industry. Meat production methods and consumption are very diverse across different regions and countries in Asia, and thus, it is impossible to cover the technological demands of all Asian countries in this review. Here, we have mainly highlighted the differences in meat production methods and consumption in Asia during recent decades and the meat technology demands of three east Asian countries, namely China, Korea, and Japan, and one south Asian country, India. A brief introduction of the meat industry, in particular the production and consumption trend in these countries, is provided in this article. The technology demands for fresh and processed meat products are then reviewed. Copyright © 2017. Published by Elsevier Ltd.

The objective of the study was to provide baseline data on the prevalence and antimicrobial susceptibility of Salmonella in different types of raw meat sausages directly accessible to the consumers in Gaborone, Botswana. A total of 300 raw sausages comprising 79 beef, 78 pork, 72 chicken, and 71 mutton samples were concurrently analyzed for the presence of Salmonella using a conventional culture method and a validated PCR method. The PCR assay results were in full concordance with those of the conventional culture method for the detection of Salmonella. Sixty-five (21.7%) of 300 samples were positive for Salmonella by both the conventional culture method and PCR assay. Even though more chicken samples contained Salmonella than did any other sausage type, the difference in the presence of Salmonella among the four sausages types was not significant. Eleven serotypes were identified, and Salmonella enterica subsp. salamae II was most prevalent in all the sausage types. Beef sausages generally had higher mesophilic bacterial counts than did the other three sausage types. However, higher microbial counts were not reflective of the presence of salmonellae. Susceptibility of the Salmonella enterica serotypes to 20 antimicrobial agents was determined, and Salmonella Muenchen was resistant to the widest array of agents and was mostly isolated from chicken sausages. Regardless of the meat of origin, all 65 Salmonella isolates were resistant to at least four antimicrobial agents: amikacin, gentamicin, cefuroxime, and tombramycin. This resistance profile group was the most common in all four sausage types, comprising 90% of all Salmonella isolates from beef, 71% from pork, 63% from mutton, and 35% from chicken. These results suggest that raw sausages pose a risk of transmitting multidrug-resistant Salmonella isolates to consumers.

Full Text Available Abstract Use of the prediction technologies is one of the directions of the research work carried out both in Russia and abroad. Meat processing is accompanied by the complex physico-chemical, biochemical and mechanical processes. To predict the behavior of meat raw material during the technological processing, a complex of physico-technological and structural-mechanical indicators, which objectively reflects its quality, is used. Among these indicators are pH value, water binding and fat holding capacities, water activity, adhesiveness, viscosity, plasticity and so on. The paper demonstrates the influence of animal proteins (beef and pork on the physico-chemical and functional properties before and after thermal treatment of minced meat made from meat raw material with different content of the connective and fat tissues. On the basis of the experimental data, the model (stochastic dependence parameters linking the quantitative resultant and factor variables were obtained using the regression analysis, and the degree of the correlation with the experimental data was assessed. The maximum allowable levels of meat raw material replacement with animal proteins (beef and pork were established by the methods of mathematical programming. Use of the information technologies will significantly reduce the costs of the experimental search and substantiation of the optimal level of replacement of meat raw material with animal proteins (beef, pork, and will also allow establishing a relationship of product quality indicators with quantity and quality of minced meat ingredients.

This study was designed to evaluate the effects of dietary treatment, packaging, and irradiation singly or in combination on the oxidative stability of broiler chicken thigh meat. A total of 120 four-week-old chickens were divided into 12 pens (10 birds/pen), and 4 pens of broilers were randomly assigned to a control oxidized diet (5% oxidized oil) or an antioxidant-added diet [500 IU of vitamin E + 200 mg/kg of butylated hydroxyanisole (BHA)] and fed for 2 wk. After slaughter, thigh meats were separated, ground, packaged in either oxygen-permeable or oxygen-impermeable vacuum bags, and irradiated at 0 or 3 kGy. Lipid oxidation (TBA-reactive substances), protein oxidation (carbonyl), and color of the meat were measured at 1, 4, and 7 d of refrigerated storage. The lipid and protein oxidation of thigh meats from birds fed the diet supplemented with antioxidants (vitamin E + BHA) was significantly lower than the lipid and protein oxidation of birds fed the control diet, whereas the lipid and protein oxidation of broilers fed the oxidized oil diet was higher than that of birds fed the control diet. Vacuum packaging slowed, but irradiation accelerated, the lipid and protein oxidation of thigh meat during storage. Dietary antioxidants (vitamin E + BHA) and irradiation treatments showed a stronger effect on lipid oxidation than on protein oxidation. A significant correlation between lipid and protein oxidation in meat was found during storage. Dietary supplementation of vitamin E + BHA and the irradiation treatment increased the lightness and redness of thigh meat, respectively. It is suggested that appropriate use of dietary antioxidants in combination with packaging could be effective in minimizing oxidative changes in irradiated raw chicken thigh meat.

The objectives of this study were, to find the prevalence and antimicrobial resistance of L. monocytogenes from a total of 116 chicken meat samples including 50 carcasses and 66 meat parts marketed in Turkey between 2008 and 2009 using immunomagnetic separation (IMS) based cultivation technique, to detect the hlyA gene for the verification of the isolates by PCR, and to identify the genoserotypes of the L. monocytogenes isolates by multiplex PCR assay. In the study, 51 L. monocytogenes colonies were isolated from 34 (29.3%) chicken meat samples (eleven [22.0%] carcasses and 23 [34.8%] pieces of meat) by IMS based cultivation technique and confirmed by PCR. According to the multiplex PCR results, all the 51 isolates were identified as genoserotype IIa (1/2a or 3a). L. monocytogenes isolates were also tested for their susceptibility to eight antibiotic (gentamicin, vancomycin, chloramphenicol, streptomycin, tetracycline, ampicillin, penicillin G, erythromycin) agents using the disk diffusion method. 14 isolates (27.45%) were susceptible to all eight antimicrobials drugs tested and the remaining 37 isolates (72.54%) were resistant to gentamicin (one isolate, 1.96%), vancomycin (four isolates, 7.84%), penicillin G (six isolates, 11.76%), streptomycin (nine isolates, 17.64%; resistant or intermediate), tetracycline (seven isolates, 13.72%) and ampicillin (six isolates, 11.76%). This study showed that antimicrobial resistance is not highly prevalent in L. monocytogenes isolated from chicken carcasses and pieces of meat. The presence of L. monocytogenes in chicken samples suggests an importance of this pathogen in chicken.

More than 27 outbreaks per year of food poisoning caused by consuming horse meat were reported in Kumamoto Prefecture (including Kumamoto City) from January 2009 to September 2011. It was found that the causative agent of the outbreaks was a protein with a molecular weight of 15 kDa that had originated from bradyzoites of Sarcocystis fayeri parasitizing the horse meat. Rabit ileal loop tests showed that pepsin treatment of homogenates of frozen horse meat containing the cysts of S. fayeri induced loss of toxicity, presumably by digestion of the proteinous causative agent(s). Slices of horse meat containing the cysts were frozen at below -20°C for various periods. The cysts were collected after thawing the slices, then treated in an artificial stomach juice containing pepsin. The bradyzoites of the cysts kept at -20°C for 48 hr or more completely disappeared. Simultaneously, the 15 kDa protein also disappeared in the frozen cysts. After notifying the public and recommending freezing treatment of horse meat, no subsequent cases of food poisoning were reported. This indicates that freezing of horse meat is effective to prevent the occurrence of food poisoning caused by consuming raw horse meat containing S. fayeri.

The role of red meat in a balanced diet.

Ruxton, Carrie

Lean red meat is rich in essential nutrients, such as iron and zinc. Recent changes in farming practice have lowered the fat content of meat significantly. Observational studies have associated high meat consumption with negative health outcomes, but these studies have limitations. The only consistent data relate to colorectal cancer, although it is unclear whether the risk relates to all red meat or to processed or overcooked meats only. The UK government has recently recommended that high consumers of red meat should reduce their intake to 500g per week, although average meat consumption is actually below this figure. This article describes patterns of meat consumption, discusses associations with health and offers guidance on how patients can consume meat as part of a healthy, balanced diet.

Attention is paid to the advantages and disadvantages of manure treatment at a chicken farm with regard to an efficient use of energy in the meat chicken production. The possibility to reduce or to improve the energy consumption, while maintaining the planned reduction of ammonia emission at the stable level, is investigated. By drying the manure, produced by the chickens, quickly, the microbiological processes and therefore the production of ammonia can be prevented. It is concluded that by using floor heating the energy consumption can be reduced, but the ammonia emission not. Keeping meat chickens on a so-called (partially) trampoline floor is not a good alternative for the conventional housing method. Reduction of the ammonia emission causes an increase of the energy consumption. If the ammonia emission of meat chickens on a raised floor is reduced by 90% the electricity consumption will increase 0.18 kWh per chicken, but the use of natural gas will be reduced by 8-10%. By improving the energy efficiency of the drying process (aeration) and determining the optimal climate control for keeping meat chickens on a raised stable litter floor, it appears to be possible to decrease the energy consumption and to improve the energy efficiency while maintaining the planned ammonia reduction. 8 figs., 4 tabs., 7 appendices, 11 refs.

A design for an automatic line for minced meat production according to new production technology based on an innovative meat milling method is proposed. This method allows the necessary degree of raw material comminution at the stage of raw material preparation to be obtained, which leads to production intensification due to the traditional meat mass comminution equipment being unnecessary. To ensure consistent quality of the product obtained, the use of on-line automatic control of the technological process for minced meat production is envisaged. This system has been developed using artificial intelligence methods and technologies. The system is trainable during the operation process, adapts to changes in processed raw material characteristics and to external impacts that affect the system operation, and manufactures meat shavings with minimal dispersion of the typical particle size. The control system includes equipment for express analysis of the chemical composition of the minced meat and its temperature after comminution. In this case, the minced meat production process can be controlled strictly as a function of time, which excludes subjective factors for assessing the degree of finished product readiness. This will allow finished meat products with consistent, targeted high quality to be produced.

CLOSTRIDIUM PERFRINGENS IN MEAT AND MEAT PRODUCTS.

HALL, H E; ANGELOTTI, R

1965-05-01

A total of 262 specimens of meat and meat dishes were examined for the presence of Clostridium perfringens. Of this total, 161 were raw, unprocessed beef, veal, lamb, pork, or chicken; 101 were processed meats and meat dishes. C. perfringens was isolated from 113 (43.1%) of these specimens. The highest percentage of contamination (82%) was found in veal cuts, and the lowest (4.7%) in sliced sandwich meats and spreads. Only 2 of the 113 isolates were shown to produce heat-resistant spores, which indicates a very low incidence (0.8%) of contamination. These findings indicate that outbreaks of C. perfringens food-borne disease in the Cincinnati area are caused principally by the contamination of the food with vegetative cells or spores of the organism after cooking. Studies of the effects of various holding temperatures on the growth of C. perfringens indicated that, in the range of 5 to 15 C, no multiplication would occur, but that viable cells would still be present at the end of a 5-day holding period. Extremely rapid growth occurred at temperatures around 45 C, and complete inhibition of growth was accomplished between 49 and 52 C.

Feeding raw meat-based diets (RMBDs) to companion animals has become increasingly popular. Since these diets may be contaminated with bacteria and parasites, they may pose a risk to both animal and human health. The purpose of this study was to test for the presence of zoonotic bacterial and parasitic pathogens in Dutch commercial RMBDs. We analysed 35 commercial frozen RMBDs from eight different brands. Escherichia coli serotype O157:H7 was isolated from eight products (23 per cent) and extended-spectrum beta-lactamases-producing E coli was found in 28 products (80 per cent). Listeria monocytogenes was present in 19 products (54 per cent), other Listeria species in 15 products (43 per cent) and Salmonella species in seven products (20 per cent). Concerning parasites, four products (11 per cent) contained Sarcocystis cruzi and another four (11 per cent) S tenella In two products (6 per cent) Toxoplasma gondii was found. The results of this study demonstrate the presence of potential zoonotic pathogens in frozen RMBDs that may be a possible source of bacterial infections in pet animals and if transmitted pose a risk for human beings. If non-frozen meat is fed, parasitic infections are also possible. Pet owners should therefore be informed about the risks associated with feeding their animals RMBDs. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

A quantitative risk assessment (RA) model was developed to describe the risk of campylobacteriosis linked to consumption of raw milk sold in vending machines in Italy. Exposure assessment was based on the official microbiological records of raw milk samples from vending machines monitored by the regional Veterinary Authorities from 2008 to 2011, microbial growth during storage, destruction experiments, consumption frequency of raw milk, serving size, consumption preference and age of consumers. The differential risk considered milk handled under regulation conditions (4°C throughout all phases) and the worst time-temperature field handling conditions detected. Two separate RA models were developed, one for the consumption of boiled milk and the other for the consumption of raw milk, and two different dose-response (D-R) relationships were considered. The RA model predicted no human campylobacteriosis cases per year either in the best (4°C) storage conditions or in the case of thermal abuse in case of boiling raw milk, whereas in case of raw milk consumption the annual estimated campylobacteriosis cases depend on the dose-response relationships used in the model (D-R I or D-R II), the milk time-temperature storage conditions, consumer behaviour and age of consumers, namely young (with two cut-off values of ≤5 or ≤6 years old for the sensitive population) versus adult consumers. The annual estimated cases for young consumers using D-R II for the sensitive population (≤5 years old) ranged between 1013.7/100,000 population and 8110.3/100,000 population and for adult consumers using D-R I between 79.4/100,000 population and 333.1/100,000 population. Quantification of the risks associated with raw milk consumption is necessary from a public health perspective and the proposed RA model represents a useful and flexible tool to perform future RAs based on local consumer habits to support decision-making on safety policies.

Animal and aquatic meats represent important sources of dietary protein and micro-nutrients. Although red and processed meats carry some risks for human health, sensory and nutritional advantages drive meat consumption. Therefore, it is important to understand how meat processing and cooking influence healthiness. The research aim was to investigate relationships of meat composition (proximates, amino acids and minerals) and cooking conditions (raw, 90 s microwave, 200 °C oven for 10 or 30 min) on protein digestibility, for a selection of four animal (beef, chicken, pork, kangaroo) and four aquatic meats (salmon, trout, prawn, oyster). Lean meats were minced before cooking followed by in vitro gastro-intestinal digestion and analysed for progress of hydrolysis, and size ranges of peptides using MALDI-TOF-MS. Correlation matrix analysis between compositional and functional parameters indicated that digestibility was significantly linked with protein and metal concentrations, likely reflecting moisture-dependent solubility and inter-mixing of sarcoplasmic metallo-proteins and insoluble myofibrillar proteins.

Campylobacter and Salmonella are leading causes of foodborne illnesses worldwide, vastly harboured by raw meat as their common food reservoir. Both microbes are prevalent in meat processing environments in the form of biofilms that contribute to cross-contamination and foodborne infection. This study applied raw meat juice (chicken juice and pork juice) as a minimally processed food model to study its effects on bacterial biofilm formation. Meat juice was collected during the freeze-thaw process of raw meat and sterilized by filtration. In 96-well polystyrene plates and glass chambers, supplementation of over 25% meat juice (v/v) in laboratory media led to an increase in biofilm formation of Campylobacter and Salmonella. During the initial attachment stage of biofilm development, more bacterial cells were present on surfaces treated with meat juice residues compared to control surfaces. Meat juice particulates on abiotic surfaces facilitated biofilm formation of Campylobacter and Salmonella under both static and flow conditions, with the latter being assessed using a microfluidic platform. Further, the deficiency in biofilm formation of selected Campylobacter and Salmonella mutant strains was restored in the presence of meat juice particulates. These results suggested that meat juice residues on the abiotic surfaces might act as a surface conditioner to support initial attachment and biofilm formation of Campylobacter and Salmonella. This study sheds light on a possible survival mechanism of Campylobacter and Salmonella in meat processing environments, and indicates that thorough cleaning of meat residues during meat production and handling is critical to reduce the bacterial load of Campylobacter and Salmonella.

The aim of the investigation was to evaluate the content of amino acids and the quality of protein in Brussels sprouts. The investigation included the raw material, cooked sample and two types of frozen product stored at -20 C for 12 months and then prepared for consumption. The frozen products investigated were obtained using the traditional method (blanching before freezing) and the modified method (cooking before freezing, then defrosting and heating in microwave oven after refrigerated storage) of the ready-to-eat type. Brussels sprouts, both fresh and prepared for consumption, were a good source of protein and amino acids. Proline and glutamic acid were dominating; leucine and tyrosine with phenylalanine were limiting amino acids. The product obtained by modified method contained 16% less amino acids in 16 g N than the raw material and 14% less than the raw material after cooking, and also 10% lower than that of the traditionally obtained product.

de Boer, Joop; Schösler, Hanna; Aiking, Harry

2014-05-01

Adapting Western meat consumption to health and sustainability challenges requires an overall reduction of industrially produced animal proteins plus a partial replacement by plant proteins. Combining insights on food, environment, and consumers, this paper aims to explore change strategies that may help to meet these challenges, such as promoting smaller portions of meat ("less"), smaller portions using meat raised in a more sustainable manner ("less but better"), smaller portions and eating more vegetable protein ("less and more varied"), and meatless meals with or without meat substitutes ("veggie-days"). The underlying logic of the strategies was clarified by analyzing dietary choices. A nationwide sample of 1083 Dutch consumers provided information on current eating practices and potential changes. The results show that strategies to change meat eating frequencies and meat portion sizes will appeal to overlapping but partly different segments of consumers and that these strategies can be applied to address consumers in terms of their own preferences. The strategies appeared to have different strengths and weaknesses, making them complementary pathways to facilitate step-by-step changes in the amounts and the sources of protein consumed.

Drawing upon a population survey the present paper investigates meat consumption behaviours, exploring perceived impacts for human health, animal welfare and the environment. Structured self-completion postal survey relating to red and processed meat, capturing data on attitudes, sustainable meat purchasing behaviour, red and processed meat intake, plus sociodemographic characteristics of respondents. Urban and rural districts of Nottinghamshire, East Midlands, UK, drawn from the electoral register. UK adults (n 842) aged 18-91 years, 497 females and 345 males, representing a 35·6 % response rate from 2500 randomly selected residents. Women were significantly more likely (P60 years) were more likely to hold positive attitudes towards animal welfare (Psustainability. Policy makers, nutritionists and health professionals need to increase the public's awareness of the environmental impact of eating red and processed meat. A first step could be to ensure that dietary guidelines integrate the nutritional, animal welfare and environmental components of sustainable diets.

Concentrations of environmental organic contaminants in meat and meat products and human dietary exposure: A review.

Science.gov (United States)

Domingo, José L

2017-09-01

Meat and meat products is one of the most relevant food groups in an important number of human diets. Recently, the IARC, based on results of a number of epidemiological studies, classified the consumptions of red meat and processed meat as "probably carcinogenic to humans" and as "carcinogenic to humans", respectively. It was suggested that the substances responsible of the potential carcinogenicity would be mainly generated during meat processing, such as curing and smoking, or when meat is heated at high temperatures. However, the exposure to environmental pollutants through meat consumption was not discussed. The purpose of the present paper was to review recent studies reporting the concentrations of PCDD/Fs, DL-PCBs and PAHs in meat and meat products, as well as the human exposure to these pollutants through the diet. It is concluded that the health risks derived from exposure to carcinogenic environmental contaminants must be considered in the context of each specific diet, which besides meat and meat products, includes other foodstuffs containing also chemical pollutants, some of them with carcinogenic potential. Anyhow, meat and meat products are not the main food group responsible of the dietary exposure to carcinogenic (or probably carcinogenic) environmental organic pollutants.

Full Text Available Animal origin foods are widely distributed and consumed around the world due to their high nutrients availability but may also provide a suitable environment for growth of pathogenic and spoilage microorganisms. Nowadays consumers demand high quality food with an extended shelf life without chemical additives. Edible films and coatings (EFC added with natural antimicrobials are a promising preservation technology for raw and processed meats because they provide good barrier against spoilage and pathogenic microorganisms. This review gathers updated research reported over the last ten years related to antimicrobial EFC applied to meat and meat products. In addition, the films gas barrier properties contribute to extended shelf life because physicochemical changes, such as color, texture, and moisture, may be significantly minimized. The effectiveness showed by different types of antimicrobial EFC depends on meat source, polymer used, film barrier properties, target microorganism, antimicrobial substance properties, and storage conditions. The perspective of this technology includes tailoring of coating procedures to meet industry requirements and shelf life increase of meat and meat products to ensure quality and safety without changes in sensory characteristics.

The National Cholesterol Education Program recommends a diet containing less than 30 percent of calories in the form of fat, less than 10 percent in the form of saturated fat, and less than 300 mg of cholesterol per day. Since Americans' diets generally exceed these recommendations, we wished to find an easy kitchen method to reduce substantially saturated fat and cholesterol in ground meat. Raw ground meat was heated in vegetable oil and rinsed with boiling water to extract fat and cholesterol. The fat-free broth was recombined with the meat to restore flavor. The amounts of total fat, saturated fat, and cholesterol in the meat after extraction were compared with the amounts in meat cooked as patties and in stir-fried, rinsed meat. When raw ground beef containing 9.6 to 20.8 percent fat was cooked as patties and the fat poured off, 6 to 17 percent of the fat and 1.3 to 4.3 percent of the cholesterol were lost. In stir-fried, rinsed ground beef, 23 to 59 percent of the fat and 9.0 to 18.8 percent of the cholesterol were lost. When vegetable oil was used to extract fat and cholesterol from beef containing 20.7 percent fat, a mean (+/- SD) of 67.7 +/- 1.6 percent of the fat and 39.2 +/- 5.1 percent of the cholesterol were lost. The differences between conventionally cooked meat and meat prepared by the extraction of fat were significant (P less than 0.001). An average of 43 percent (range, 38 to 49) of cholesterol was extracted from a wide variety of ground meats. Although conventional cooking produced no change in fatty-acid composition as compared with raw meat, our extraction process greatly increased the ratio of unsaturated to saturated fat, from 1.32 in conventionally cooked meat to 2.92 to 4.56 in meat after extraction. Extraction resulted in the loss of 72 to 87 percent of saturated fat. This method produces a tasty meat product that is much lower in saturated fat and cholesterol than conventionally cooked meat, and that can be used in sauces, soups, and

To review New Zealand red meat and meat fat supply trends before and after the introduction of the Quality Mark standard. Review of trends in: per capita meat fat supply estimates from the Food and Agriculture Organization (FAO); carcase and meat cut composition reports of knife dissection and chemical analyses; the fate of fat trim; and a Lincoln College study of home-cooked and trimmed beef. Intervention From September 1997, the red meat industry's Quality Mark required trimming of beef and lamb cuts to no more than 5 mm external fat. (1) Trimming of fat from red meat before sale (supported by virtually all butchers) decreased the fat and saturated fat content of a red meat carcase by 30% (beef, -27%; lamb, -30%; tallow unchanged); by -8% in the total food supply; and by -17% across all meat. In 2002, fat comprised 7.4% of trimmed beef cuts, and 11.2% of all beef sold: cuts, mince, or sausages. In 2002, fat comprised 15.3% of lamb cuts; and 15.5% with mince included. (2) From 1995 to 2002, total saturated fat availability per capita in the food supply decreased by 19% (from 65 g to 53 g per day), mostly due to 7 g less saturated fat daily from red meat. (3) When combining effects (1) and (2), saturated fat per capita decreased: -27% in total food supply; -65% in red meat excluding tallow; -48% in red meat including tallow. In 1995 (without trimming), red meat contributed 25% of saturated fat in the total food supply whereas in 2002, red meat contributed 19% before (and 13% after) trimming. (4) Home trimming may remove an additional 27% of fat from beef steaks. Centralised meat processing, and Quality Mark labelling since 1997, ensured fat was trimmed from beef and lamb cuts, and reduced saturated fat in red meats by 30%. In 2002, mince and sausages accounted for nearly half of beef fat sold as red meat.

Although animal welfare is felt to be important by consumers, behavioural patterns do not fully reflect this. Rather than relating this attitude-behaviour gap to hypocrisy, this article, building on pragmatic sociological theory and an empirical study, focuses on context-dependent moral evaluations....... An analysis of focus-group interviews conducted in three countries shows that meat-related consumption practices involve several competing sets of moral conventions, and the results demonstrate that public concerns about animal welfare vary depending on whether they relate to an everyday or production context...... of making animal welfare relevant in this context in order to support consumers in moving towards products with high standards of animal welfare....

The consumption of meat products is gradually being increased by the development of livestock raising technology, industrialized farm management and international trade. This increased consumption also created new market for ready-to-eat and ready-to-cook meat products. However, these convenience meat products can be easily contaminated during the processing and storage by pathogens, and there have been many reported cases of food borne illness by meats. One of the most effective methods for the decontamination of meat products is the radiation technology. Food irradiation was the established, well-recognized and safe sterilization method. Many other countries researched the effect of irradiation on the meat products and approved the irradiation. In this article, the effectiveness, the international acceptance, the economics and the research trend of irradiation on meat products have been reviewed. Also, the policy plans for the early approval of the irradiated meat products in Korea and the promotion policy of irradiated meats in market were discussed.

However, these convenience meat products can be easily contaminated during the processing and storage by pathogens, and there have been many reported cases of food borne illness by meats. One of the most effective methods for the decontamination of meat products is the radiation technology. Food irradiation was the established, well-recognized and safe sterilization method. Many other countries researched the effect of irradiation on the meat products and approved the irradiation. In this article, the effectiveness, the international acceptance, the economics and the research trend of irradiation on meat products have been reviewed. Also, the policy plans for the early approval of the irradiated meat products in Korea and the promotion policy of irradiated meats in market were discussed

China's rapidly growing economy is accelerating its materialization process and thereby creating serious environmental problems at both local and global levels. Understanding the key drivers behind China's mass consumption of raw materials is thus crucial for developing sustainable resource management and providing valuable insights into how other emerging economies may be aiming to accomplish a low resource-dependent future. Our results show that China's raw material consumption (RMC) rose dramatically from 11.9 billion tons in 1997 to 20.4 billion tons in 2007, at an average annual growth rate at 5.5%. In particular, nonferrous metal minerals and iron ores increased at the highest rate, while nonmetallic minerals showed the greatest proportion (over 60%). We find that China's accelerating materialization process is closely related to its levels of urbanization and industrialization, notably demand for raw materials in the construction, services, and heavy manufacturing sectors. The growing domestic final demand level is the strongest contributor of China's growth in RMC, whereas changes in final demand composition are the largest contributors to reducing it. However, the expected offsetting effect from changes in production pattern and production-related technology level, which should be the focus of future dematerialization in China, could not be found.

Diet and lifestyle are modifiable factors involved in the development and prevention of non-communicable diseases, including cardiovascular disease. Nut consumption, particularly walnut intake, has been inversely related to incident coronary heart disease (CHD) in observational studies and to improved lipid profiles in short-term feeding trials. To assess the potential functional effect associated with the regular consumption of walnut-enriched restructured meat products in subjects at risk for cardiovascular disease (CVD). A crossover single-dose bioavailability study (n = 3) using gamma-tocopherol as exposure marker and a crossover unblinded dietary intervention study (5 weeks) in subjects at risk (n = 25). Dietary intervention consisted of regular consumption of the meat product, with or without walnuts, five times per week for five weeks with a 1-month washout in between. Overnight fasting blood samples were collected on days 0, 12, 21, 28 and 35, coinciding with blood pressure and body weight recordings. Participants were asked to complete a diet record throughout the study. The functional effects were assessed using clinically relevant and related biomarkers of CHD: serum total, HDL and LDL cholesterol, triacylglycerols, homocysteine, vitamins B(6) and B(12), folic acid, alpha-tocopherol and platelet function test (obturation time). The regular consumption of walnut-enriched meat products compared with that of the restructured meat products without added walnuts provokes a decrease in total cholesterol of 6.8 mg/dl (CI(95%): -12.8, -0.85). Compared to baseline (mixed diet), meat products with walnuts decreased total cholesterol (-10.7 mg/dl, CI(95%): -17.1, -4.2), LDL cholesterol (-7.6 mg/dl, CI(95%): -2.2, -13.0) and body weight (-0.5 kg, CI(95%): -0.1, -0.9) and increased gamma-tocopherol (8.9 mg/dl, CI(95%): 1.0, 16.8). The restructured meat products with added walnuts supplied in this study can be considered functional foods for subjects at high risk for

Olmedilla-Alonso, Begoña; Jiménez-Colmenero, Francisco; Sánchez-Muniz, Francisco J

2013-12-01

This review deals with the two major aspects to be considered in the context of meat-based functional foods and human health. One involves the different strategies used to improve (increase or reduce) the presence of bioactive (healthy and unhealthy) compounds in meat and meat products in order to develop potential meat-based functional foods; these strategies are basically concerned with animal production practices, meat processing and storage, distribution and consumption conditions. Since the link between the consumption of those foods and their potentially beneficial effects (improving health and/or reducing the risk of several chronic diseases) needs to be demonstrated scientifically, the second aspect considered is related to intervention studies to examine the functional capacity of meat-based potentially functional foods in humans, discussing how the functionality of a food can be assessed in terms of its effects on health in relation to both target body functions and risk factors.

In order to test the possible application of alcohol brine freezing to Japanese horse mackerel (Trachurus japonicus) for raw consumption, the quality and taste of fish frozen by direct immersion in 60% ethanol brine at -20, -25 and -30°C was compared with those by air freezing and fresh fish without freezing. Cracks were not found during the freezing. Smell of ethanol did not remain. K value, an indicator of freshness, of fish frozen in alcohol brine was less than 8.3%, which was at the same level as those by air freezing and fresh fish. Oxidation of lipid was at the same level as air freezing does, and lower than that of fresh fish. The pH of fish frozen in alcohol brine at -25 and -30°C was 6.5 and 6.6, respectively, which were higher than that by air freezing and that of fresh fish. Fish frozen in alcohol brine was better than that by air and at the same level as fresh fish in total evaluation of sensory tests. These results show that the alcohol brine freezing is superior to air freezing, and fish frozen in alcohol brine can be a material for raw consumption. The methods of thawing in tap water, cold water, refrigerator, and at room temperature were compared. Thawing in tap water is considered to be convenient due to the short thaw time and the quality of thawed fish that was best among the methods.

Lead, cadmium and chromium levels were determined in different raw and boiled portions of Norway lobster caught in the central Adriatic Sea (Italy). In raw specimens, the lowest concentrations were always detected in the white meat. Lead and cadmium content in the edible portion never exceeded the maximum levels set by European legislation. The highest cadmium and chromium values (0.47 ± 0.04 and 0.62 ± 0.13 mg/kg wet weight, respectively) were detected in the brown meat, while the highest lead concentrations were found in the exoskeleton (0.21 ± 0.01 mg/kg wet weight). Also, the boiled samples showed the lowest metal levels in the white meat, even if a significant increase (p < 0.01) was found for lead and cadmium compared to the corresponding raw portions. Among metals, chromium showed the highest concentrations in both raw and boiled portions, but up to now, the European legislation did not envisage any limits in seafood.

The most likely human exposure to bovine spongiform encephalopathy (BSE) is dietary, through beef mechanically recovered meat (MRM) and head meat used in burgers, sausages and other meat products. The majority, reportedly 90% of beef MRM and 80% of head meat, was used in burgers. To enable quantification of UK dietary exposure to BSE, we quantified bovine carcass meat consumed as burgers, sausages and other meat products by birth cohort, gender and calendar period (1980-1989, 1990-1996). Synthesis of dietary data (cross-sectional National Dietary and Nutrition Surveys, and serial National Food Surveys and Realeat Surveys) to simulate weekly consumption by one-thousandth of the UK population in each year from 1980 to 1996. In 1980-1989, the highest number of consumers (per 7 days) of all three food groups was in the 1940-1969 birth cohort - averaging 3.7 million male consumers of burgers, 2.6 million of sausages and 8.5 million of other meat products. The post-1969 birth cohort had the next highest number of consumers of burgers (1.8 million males). In 1990-1996, consumer numbers declined for the two older cohorts, most strikingly for burgers (down to 2.5 million males in the 1940-1969 cohort). The 1940-1969 cohort retained the highest number of consumers of sausages and other meat products, and second place for burgers. Male consumption was higher, even in the pre-1940 birth cohort where, for demographic reasons, female consumers outnumbered males. In the post-1969 birth cohort, female consumption of bovine carcass meat weight as burgers increased from 68 tonnes in 1980-1989 to 81 tonnes in 1990-1996, and male consumption increased more markedly (by 41%) from 84 tonnes to 119 tonnes; and similarly for other meat products. Properly marshalled age-group and gender-specific consumption data contribute to a clearer understanding of the demography of those who were at risk of dietary exposure to BSE and of when their exposure intensity was greatest.

The consumption of cetacean meat is geographically common and often of undetermined sustainability. Besides, it can expose humans to contaminants and zoonotic pathogens. The illegality of possessing cetacean meat was likely under-reported in some countries due to lack of attention paid by the officials although DNA analysis of market products helped to show such practices. We developed two monoclonal antibodies against synthetic peptides of myoglobin (Mb) for constructing a rapid immune colloidal gold strip. Only cetacean Mb is capable of binding to both antibodies and presents positive signal while the Mb from other animals can bind only 1 of the antibodies and presents negative result. The strip for cetacean meat would be an applicable and cost-effective test for field inspectors and even the general public. It contributes to increase the reporting capacity and coverage of illegal cetacean meat possession, which has implications for global cetacean conservation and public health.

Changes in consumer demand of meat products as well as increased global competition are causing an unprecedented spur in processing and ingredient system developments within the meat manufacturing sector. Consumers demand healthier meat products that are low in salt, fat, cholesterol, nitrites and calories in general and contain in addition health-promoting bioactive components such as for example carotenoids, unsaturated fatty acids, sterols, and fibers. On the other hand, consumers expect these novel meat products with altered formulations to taste, look and smell the same way as their traditionally formulated and processed counterparts. At the same time, competition is forcing the meat processing industry to use the increasingly expensive raw material "meat" more efficiently and produce products at lower costs. With these changes in mind, this article presents a review of novel ingredient systems and processing approaches that are emerging to create high quality, affordable meat products not only in batch mode but also in large-scale continuous processes. Fat replacers, fat profile modification and cholesterol reduction techniques, new texture modifiers and alternative antioxidant and antimicrobial systems are being discussed. Modern processing equipment to establish continuously operating product manufacturing lines and that allow new meat product structures to be created and novel ingredients to be effectively utilized including vacuum fillers, grinders and fine dispersers, and slicers is reviewed in the context of structure creation in meat products. Finally, trends in future developments of ingredient and processing systems for meat products are highlighted.

Irradiation of bovine meat: effect of heme-iron concentration

2002-01-01

The irradiation is often used, nowadays, for meat conservation and it is important to know how much this process interferes with the nutritional quality of the meat. In this study round cut meat, ground and steaks (from a local supermarket) was irradiated with doses of O; 1; 2; 3; 4; 5; 7,5 and 10 kGy (JS-7500 Nordium Inc -Canada) and the interference of irradiation and the process of food preparation on heme-iron (H Fe) content was determined. Half of the sample was kept raw and the other half was grilled in a pre-warmed oven at 250 deg C for 9 min and a controlled humidity of 70%. The chemical composition, the total iron (T Fe) (EM) and the heme iron concentration were determined (Hornsey,1956) and the sensorial quality evaluated. The average T Fe concentration of raw and ground , ground and grilled, raw steaks and grilled steak meat, on dry and degreased basis was 113 mug/g, 121 mug/g , 91 mug/g and 77 mug/g; and the H Fe concentration 105 mug/g (93% of T Fe) , 88 mug/g (73% of T Fe), 90 mug/g (99% of T Fe) and 52 mug/g (68% of T Fe) respectively. Data were evaluated by ANOVA with fixed effects and multiple comparisons. The irradiation neither altered the chemical composition nor the proportion of heme iron of meat. The preparation conditions (temperature, cooking time, environment humidity, meat presentation) of the sample interfered more with the heme iron content than the irradiation. With the sensorial analysis we verified that meats irradiated with doses of 3 kGy were better evaluated in softness and succulency attributes than the others. Meat submitted to irradiation doses up to 3 kGy were accepted by the specialists' panel. (author)

A vane pump-grinder system was extended to enable the manufacture of finely dispersed emulsion-type sausages by constructing and attaching a high-shear homogenizer at the outlet. We hypothesized that the dispersing capabilities of the extended system may be improved to the point of facilitating meat-fat emulsification due to an overall increased volumetric energy input EV . Coarsely ground raw material mixtures were processed to yield meat batters at varying volume flow rates (10 to 60 L/min) and rotational rotor speeds of the homogenizer nrotor (1000 to 3400 rpm). The normalized torques acting on pump, grinder, and homogenizer motors were recorded and unit power consumptions were calculated. The structure of the manufactured meat batters and sausages were analyzed via image analysis. Key physicochemical properties of unheated and heated batters, that is, texture, water-binding, color, and solubilized protein were determined. The mean diameter d10 of the visible lean meat particles varied between 352 and 406 μm whereas the mean volume-surface diameter d32 varied between 603 and 796 μm. The lightness L* ranged from 66.2 to 70.7 and correlated with the volumetric energy input and product structure. By contrast, varying process parameters did not impact color values a* (approximately 11) and b* (approximately 8). Interestingly, water-binding and protein solubilization were not affected. An exponential process-structure relationship was identified allowing manufacturers to predict product properties as a function of applied process parameters. Raw material mixtures can be continuously comminuted, emulsified, and subsequently filled into casings using an extended vane pump-grinder. © 2016 Institute of Food Technologists®

Full Text Available ObjectiveWe aimed to identify dietary patterns (DPs of Portuguese adults, to assess their socioeconomic, demographic, lifestyle determinants, and to identify their impact on health.DesignEpiDoC 2 study included 10,153 Portuguese adults from the EpiDoC Cohort, a population-based study. In this study, trained research assistants using computer-assisted telephone interview collected socioeconomic, demographic, dietary, lifestyles, and health information from March 2013 to July 2015. Cluster analysis was performed, based on questions regarding the number of meals, weekly frequency of soup consumption, vegetables, fruit, meat, fish, dairy products, and daily water intake. Factors associated with DP were identified through logistic regression models.ResultsTwo DPs were identified: the “meat dietary pattern” and the “fruit & vegetables dietary pattern.” After multivariable adjustment, women (OR = 0.52; p < 0.001, older adults (OR = 0.97; p < 0.001, and individuals with more years of education (OR = 0.96; p = 0.025 were less likely to adopt the “meat dietary pattern,” while individuals in a situation of job insecurity/unemployment (OR = 1.49; p = 0.013, Azores island residents (OR = 1.40; p = 0.026, current smoking (OR = 1.58; p = 0.001, daily alcohol intake (OR = 1.46; p = 0.023, and physically inactive (OR = 1.86; p < 0.001 were positively and significantly associated with “meat dietary pattern.” Moreover, individuals with depression symptoms (OR = 1.50; p = 0.018 and the ones who did lower number of medical appointments in the previous year (OR = 0.98; p = 0.025 were less likely to report this DP.ConclusionOur results suggest that unhealthy DPs (meat DP are part of a lifestyle behavior that includes physical inactivity, smoking habits, and alcohol consumption. Moreover, depression symptoms are also associated with unhealthy DPs.

Some technological aspects of combined processing of meat by heat and ionizing radiations

1974-01-01

The paper discusses the use of ionizing radiation to prolong the storage life of meat and meat products. Irradiating raw meat with doses of 0.4-0.6 Mrad increased storage life up to two months at low above-zero C temperatures. The difficulty of inhibiting autolytic processes during storage of irradiated raw meat led to searches for combined methods of meat treatment. A series of experiments was staged with pre-irradiation heating of meat up to 75, 77, and 80 0 C in order to see how cathepsin activity is affected by the duration and temperature of heating in the case of combined treatment. To increase the resistance of meat products to microbial damage, tests were carried out in which meat was exposed to short-term but intensive heat by immersing it in hot (130-160 0 C) vegetable oil (frying grease). The results are presented in the form of tables and diagrams. (E.T.)

This review examines the chemistry of nitrite curing of meat and meat products as it relates to the development of cured meat color and provides a detailed account of how nitrite-free processed meats could be prepared using the preformed cooked cured-meat pigment (CCMP). Thus, a chemical description of meat color, both raw and cooked, and characterization of nitrosylheme pigments follows. Based on electron paramagnetic resonance (EPR), visible and infrared spectroscopic studies, evidence has been provided to support the hypothesis that the chemical structure of the preformed CCMP is identical to that of the pigment prepared in situ after thermal processing of nitrite-cured meat and is in fact a mononitrosylheme complex. An appendix, which describes the basic principles of EPR spectroscopy used in the context of this review, is attached.

The effect of particle size, method of particle size reduction (grinding, flaking, slicing) and alginate or Fibrimex(™) binding systems on processing properties of restructured beef were investigated. The size of semimembranosus muscles was reduced with a meat slicer, grinder or flaker (Comitrol) through machine openings that were 2, 4 and 8 mm in size. Bind of meat pieces in raw and cooked beef steakettes were measured. Sensory evaluation to determine the effect of method of size reduction on texture of beef steakettes was done only on steakettes manufactured with alginate. Beef steakettes manufactured with the alginate binding system had significantly (p meat for the manufacture of restructured beef steakettes resulted in a higher raw bind than did either grinding or flaking the meat. Significant (p meat was sliced than when it was ground or flaked. However, when Fibrimex was used, bind was stronger when sliced meat was used. The alginate system resulted in higher binds for cooked product when particle size was smaller but with the Fibrimex system bind was higher when particle sizes were larger. A consumer panel on alginate restructured steakettes showed no preference for the texture produced by the different methods of particle size reduction.

Meat has been widely consumed as an important protein source in daily life of human. Furthermore, with busy and intense urban lifestyle, processed food is now one of the main protein sources of one’s diet. Consumers rely on the food labeling to decide if the meat product purchased is safe and reliable. Therefore, it is important to ensure the food labeling is done in a correct manner to avoid consumer fraud. More consumers are now concern about the food quality and safety as compared to before. This study described the meat species identification and detection method using Polymerase Chain Reaction (PCR) in 8 types of meats (cattle, buffalo, goat, sheep, chicken, duck, pork and horse). The objective of this study is to decide on the specificity of oligonucleotide sequences obtained from previous study. There were 5 proposed oligonucleotide primer in this study. The main important finding in this work is the specificity of oligonucleotide primers to raw meats. It if found that the oligonucleotide primers proposed were not specific to the local raw meat species. Therefore, further study is needed to obtain a species-specific oligonucletide primers for PCR, in order to be applied in food product testing

Full Text Available In Brazil, the demand for sustainably certified seafood is increasing and retailers have promised to source all seafood from sustainable sources by 2015. In the southern portion of the country, elasmobranch meat is sold as cação, and consumers are often unaware that cação refers to any type of elasmobranch. The present study used questionnaires to investigate the lay public’s knowledge of elasmobranch meat sold in a Brazilian city. Shoppers were surveyed at supermarkets in Curitiba, the largest city in southern Brazil. The study revealed that people do not link commercialized cação meat to sharks and rays (Elasmobranchii, with more than half of respondents who claimed to have already eaten cação did not think they had ever eaten shark or ray. The educational profile of interviewees suggests that this lack of knowledge may be even more common in other segments of Brazilian society. Therefore, we suggest that ecological information about elasmobranchs should be included in Brazilian elementary and high school curricula. Such a measure has the potential to modify behavior, create awareness, and stimulate responsibility throughout society, with the primary goal of reducing shark meat consumption and, ultimately, guaranteeing the long term conservation of marine resources.

Intensive farming of livestock along with recent food scandals and consumer deception have increased awareness about risks for human nutrition. In parallel, the demand for meat obtained under more natural conditions from animals that can freely forage has largely increased. Interestingly, the consumption of game meat has not become more common despite its excellent quality and content of polyunsaturated fatty acids (PUFAs). We addressed the question if game meat fatty acid composition is modified through kitchen preparation. By analysing muscle fatty acid (FA) composition (polar and total lipids) of five European game species in a raw and a processed state, we aimed to quantify the proportion of PUFA that are oxidised and hydrogenated during processing. All game meat species originated from local hunters and free-living individuals. To mimic a realistic situation a professional chef prepared the meat samples with gentle use of heat in a standardised way. Expectedly, the overall content of polyunsaturated fatty acids declined during the cooking process but the decrease size was cooking does not substantially alter its favourable fatty acid composition. Further research is needed to elucidate species-specific differences and the role of habitat quality and locomotion for tissue composition.

Five treatments, including (1) control (none added); (2) 100 ppm oregano essential oil; (3) 300 ppm oregano essential oil; (4) 400 ppm oregano essential oil; and (5) 5 ppm butylated hydroxyanisole (BHA), were prepared with ground boneless, skinless chicken breast meat and used for both raw and cooked meat studies. For raw meat study, samples were individually packaged in oxygen-permeable bags and stored in a cold room (4 °C) for 7 days. For cooked meat study, the raw meat samples were vacuum-packaged in oxygen-impermeable vacuum bags and then cooked in-bag to an internal temperature of 75 °C. After cooling to room temperature, the cooked meats were repackaged in new oxygen-permeable bags and then stored at 4 °C for 7 days. Both raw and cooked meats were analyzed for lipid and protein oxidation, volatiles, and color at 0, 3, and 7 days of storage. Oregano essential oil significantly reduced (p oil at 400 ppm showed the strongest effect for all these parameters. Hexanal was the major aldehyde, which was decreased significantly (p oil treatment, in cooked meat. Overall, oregano essential oil at 100–400 ppm levels could be a good preservative that can replace the synthetic antioxidant in chicken meat. PMID:27338486

Full Text Available The objective of this article is to present a possible use of roasted cocoa hulls, which currently represents an industrial surplus in the grain processing industries, and is sold with companies that produce concentrates for animals. On daily processing plants will produce about 4 tons of roasted cocoa peel, this would be a great source to produce fiber for human consumption. The present investigation was consist in obtaining raw fiber from roasted cocoa peel, and through specific laboratory tests to assess their possible use for human consumption, thus able to incorporate this product into the production process. In relation to the environment, minimize the impact of the production process, because it would be taking advantage of a normal by product of production, which elsewhere is a waste that could be coming to the landfill, creating a burden on the soil resource and that despite biodegradable, while decomposition is classified as a contaminant of this medium.

Full Text Available Toxoplasma gondii is one of the most widespread parasites in humans and can cause severe illness in immunocompromised individuals. However, its role in healthy people is probably under-appreciated. The complex epidemiology of this protozoan recognizes several infection routes but consumption of contaminated food is likely to be the predominant one. Among food, consumption of raw and undercooked meat is a relevant route of transmission, but the role of different meat producing animal species and meats thereof is controversial.The aim of the present work is to summarize and analyse literature data reporting prevalence estimates of T. gondii in meat animals/meats.We searched Medline, Web of Science, Science Direct (last update 31/03/2015.Relevant papers should report data from primary studies dealing with the prevalence of T. gondii in meat from livestock species as obtained through direct detection methods. Meta-analysis and meta-regression were performed.Of 1915 papers screened, 69 papers were included, dealing mainly with cattle, pigs and sheep. Pooled prevalences, based on random-effect models, were 2.6% (CI95 [0.5-5.8] for cattle, 12.3% (CI95 [7.6-17.8] for pigs and 14.7% (CI95 [8.9-21.5] for sheep. Due to the high heterogeneity observed, univariable and multivariable meta-regression models were fitted showing that the geographic area for cattle (p = 0.032, the farming type for pigs (p = 0.0004 and the sample composition for sheep (p = 0.03 had significant effects on the prevalences of Toxoplasma detected/estimated. Moreover, the role of different animal species was dependent on the geographic location of animals' origin.Limitations were due mainly to a possible publication bias.The present work confirms the role of meat, including beef, as T. gondii sources, and highlights the need for a control system for this parasite to be implemented along the meat production chain. Moreover, consumer knowledge should be strengthened in order to reduce

Meat products may be vehicles of bacterial pathogens to humans, and Salmonella spp., Campylobacter spp., and Shiga toxin-producing Escherichia coli (STEC) are the most relevant. The aim of this study was to generate data on prevalence of these three pathogens in 552 samples of meat products (hot dogs, pork sausages, raw ground beef, and raw chicken legs) sold at retail in the city of Sao Paulo, Brazil. Salmonella spp. was detected in 5.8% (32/552) of samples, comprising pork sausages 62.5% (20/32) and chicken legs 37.5% (12/32). The counts of Salmonella spp. were low, ranging from Salmonella Typhimurium (28.1%), Salmonella I 4,[5],12:i:- (15.6%), Salmonella Enteritidis (12.5%), Salmonella Derby, and Salmonella Brandenburg (9.4%). Campylobacter spp. was detected in 33 samples (6.0%), comprising chicken legs (82%) and ground beef (18%). All samples were negative for STEC. These results suggest that meat products when subjected to inadequate cooking and/or cross-contamination with other products ready for consumption can lead to occurrence of outbreaks, highlighting the risks associated with them.

The distribution of total arsenic in different portions of Norway lobster (Nephrops norvegicus L., Crustacea) was studied both in fresh samples and after a boiling process. All individuals (n = 80) were selected of medium standard commercial size (13-15 cm). The highest mean concentrations (26.86 ± 1.57 mg/kg wet weight (ww)) were found in the raw brown meat of the crustacean, probably due to its detoxification role, whereas the lowest mean values (15.97 ± 0.85 mg/kg ww) were in the raw exoskeleton. The raw white meat reported mean values of 16.09 ± 0.61 mg/kg ww. The levels of arsenic contamination detected in the boiled portions showed a significant (p < 0.01) decrease compared to the raw portions, as a consequence of solubilization phenomena. In fact, a large amount of arsenic from raw lobsters was transferred to the corresponding boiling broth. In the most commonly consumed portion, the white meat, only slight losses (7.22%) in total arsenic content were observed compared to the raw portion.

Recently the isolation of methicillin-resistant Staphylococcus aureus (MRSA) strains from several food-producing animals has been reported. During slaughtering of MRSA-positive animals, contamination of carcasses with MRSA may occur and consequently the meat of these animals may get contaminated. The aim of this study was to estimate the prevalence of MRSA in raw meat samples from the retail trade. Samples of raw beef, pork, veal, lamb/mutton, chicken, turkey, fowl and game were collected from the retail trade. A detection method including a two-step enrichment in Mueller-Hinton broth+6.5% NaCl and phenol red mannitol broth containing ceftizoxime and aztreonam, followed by isolation on MRSA ID agar (bioMérieux) was evaluated and subsequently applied for the detection of MRSA in samples of raw meats. MRSA strains were isolated from 264 (11.9%) of 2217 samples analyzed. Isolation percentages for the meat species were: beef (10.6%), veal (15.2%), lamb and mutton (6.2%), pork (10.7%), chicken (16.0%), turkey (35.3%), fowl (3.4%) and game (2.2%). The majority (85%) of the isolated strains belonged to spa-types of pulsed-field gel electrophoresis (PFGE) non-typeable (NT)-MRSA, corresponding to the multilocus sequence type ST398, a type also recently isolated in the Netherlands from pigs. However, a smaller part of these strains were found to be of other ST's, possibly of human origin. Further studies are needed to elucidate transmission routes of MRSA in relation to meat and other foods and to provide the tools for preventing the spread of MRSA. At present the high prevalence of MRSA in meat has not been shown to contribute significantly to the dissemination of MRSA to humans and the possible health hazard for consumers of the presence of MRSA in foods should be further elucidated.

The present study provides a picture of the compositional figure and nutritive value of meat-based dishes typical of Italian culinary tradition. Recipes specific for a bovine meat cut (top-side) were selected among the most widespread ones in Italy: in pan, pizzaiola, cutlet, meat ball, and escalope. The total fat and cholesterol content varied depending on the ingredients utilized (extra-virgin olive oil, parmesan, egg). Meat-based dishes that utilized extra-virgin olive oil showed a significant reduction in palmitic and stearic acids and a parallel increase in oleic acid compared with raw meat; furthermore, the ratio among saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids shifted in favour of monounsaturated fatty acids. B vitamins were affected at different extent by heating; by contrast, vitamin E content increased because of the new sources of this vitamin, which masked losses due to heating. Ingredients (parmesan, discretionary salt) induced significant increases in the calcium and sodium concentrations compared with raw meat. The total iron content did not show marked differences in most of the meat-based dishes compared with raw meat; by contrast, losses in the heme-iron concentration were detected depending on the severity of heating treatments. Our findings suggest that heme iron, because of its important health aspects, might be a useful index of the nutritional quality of cooked meats.

The impact of meat consumption on high blood pressure (HBP) and obesity in children and adolescents is a subject of debate. The aim of this study was thus to evaluate the association between meat consumption and both HBP and obesity in this group. We performed a cross-sectional analysis using nationally representative samples of children and adolescents aged 9, 12, and 15 years old (n = 136,739) who were included in the Korea School Health Examination Survey (KSHES) for the 2011-2015 period. Multiple linear and logistic regression analysis was used to determine the factors influencing systolic blood pressure (SBP), diastolic blood pressure (DBP), and body mass index (BMI, kg/m 2 ) levels, and to test the strength of these relationships. Adjusted for covariates, 6.3% of those subjects who consumed >5 servings of meat (including beef, pork, and chicken) per week were obese, compared with 9.1% of the subjects who consumed 5 servings of meat/wk (systolic HBP adjusted OR: 1.30; 95% CI: 1.05-1.62; P ≤0.01, diastolic HBP adjusted OR: 1.25; 95% CI: 1.02-1.54; P 5 servings of meat/wk, those who consumed 0.05). In contrast, BMI was significantly associated with milk, fruits, and vegetables (P <0.01). Among children and adolescents, a higher level of meat consumption was associated with lower SBP, DBP, and BMI, and greater height, suggesting that consuming an appropriate amount of meat is important for healthy growth at a young age.

The present review describes the possibility of in vitro meat production with the help of advanced co-culturing methods. In vitro meat production method could be a possible alternative for the conventional meat production. Originally, the research on in vitro meat production was initiated by the National Aeronautics and Space Administration (NASA) for space voyages. The required key qualities for accepting in vitro meat for consumption would be good efficiency ratio, increased protein synthesis rate in skeletal muscles, and mimicking the conventional meat qualities. In vitro culturing of meat is possible with the use of skeletal muscle tissue engineering, stem cell, cell co-culture, and tissue culture methods. Co-culture of myoblast and fibroblast is believed as one of the major techniques for in vitro meat production. In our lab, we have co-cultured myoblast and fibroblast. We believe that a billion pounds of in vitro meat could be produced from one animal for consumption. However, we require a great deal of research on in vitro meat production.

Fermentation of meat is a traditional preservation method used widely for improving quality and shelf life of fermented meat products. Fermentation of meat causes a number of physical, biochemical, and microbial changes, which eventually impart functional properties, sensory characteristics, and nutritional aspects to these products and inhibit the growth of various pathogenic and spoilage microorganisms. These changes include acidification (carbohydrate catabolism), solubilization and gelation of myofibrillar and sarcoplasmic proteins of muscle, degradation of proteins and lipids, reduction of nitrate into nitrite, formation of nitrosomyoglobin, and dehydration. Dry-fermented sausages are increasingly being used as carrier of probiotics. The production of biogenic amines during fermentation can be controlled by selecting proper starter cultures and other preventive measures such as quality of raw materials, hygienic measures, temperature, etc.

Participation Rate as A Basis for Measuring Food Security Status of Meat

Full Text Available Food security has been developed as way for decision makers to pay more attention to this sector. It is believed that foods which are efficiently produced in one area or country may be accessed by other areas or countries. However, this concept is difficult to be implemented since almost none of countries in the world have all resources to produce what is needed by its people. Food consumption, including beef, would be better measured using participation rate which indicates a cluster of its consumer instead of using all population as a denominator for calculating per capita consumption, except for commodities whose consumer member of its cluster close to 100% of the population. For commodities whose consumers less than 50% of its cluster it is more effective to use the size of the cluster as the denominator. Diversified food consumption of animal origin in Indonesia has been indicated by the fact that it has been naturally established. Animal meat consumption diversification for many reasons is influenced by cultural, preferences or other economic status of the households. This phenomena is also indicated by the magnitude of positive cross price elasticity between beef and mutton, beef and poultry meat, and between poultry meat and fish. Therefore, every effort to push higher consumption of one meat type, will reduce the participation rate of others. Susenas data indicated participation rates for beef and buffalo meat were 26.15% (2002, 21.93% (2005, 16.18% (2008 and 16.16% (2011, while poultry meat had higher participation rate as 65.46% (2002, 63.48% (2005, 57.67% (2008 and 56.98% (2011. Application of participation rate approach on the production of beef and buffalo meat resulted in the annual percapita consumption of 6.71 kg (2002, 10.47 kg (2005, 10.82 kg (2008 and 13.11 kg (2011. It concludes that balanced participation rates of meat components (beef and poultry meat, need to be maintained as the existed diversified meat consumption

In 2013, the Norwegian Armed Forces decided to introduce a meat reduction scheme in its military mess halls, for both health reasons and environmental concerns. This article explores Norwegian soldiers' reactions to the introduction of Meat free Monday, and their attitudes towards reducing meat consumption. As of yet, Meat free Monday has not been implemented due to both structural and contextual challenges. We explore both the process and potential of the Norwegian military's Meat free Monday initiative to promote sustainable and climate friendly diets. We found significant barriers preventing the military from implementing Meat free Monday. The main reason behind the resistance to reduce meat consumption among Norwegian soldiers was meat's associations with protein, masculinity and comfort. Our results underline the importance of acknowledging the social and cultural role of food. The study is qualitative and uses focus group interviews as its main methodology.

Full Text Available A study was conducted to investigate the effect of two dietary energy sources, soy bean oil, and sucrose on regulatory mechanisms of meat preservation. Twenty one day-old Hubbard commercial broilers were randomly allocated into two dietary treatment groups with six replicates per treatment, and four broilers per replicate. All birds were coded for the influence of energy source: fat based diet (FD, and sugar based diet (SD. Formulated grower diets were isonitrogenous and isocaloric. The chickens were slaughtered and then boneless, skinless ground chicken tight meat was prepared. Both raw and cooked meats were analyzed for lipid and protein oxidation, and sensory panel evaluation. In addition, meat from the small muscles of the raw thigh was used to evaluate other meat quality characteristics. Proximate analyses showed no significant differences between both dietary treatments on protein, ash and moisture percentage values. Meat samples of the group that was fed FD showed higher significant values of both TBARS and total carbonyl at day 7 of storage time. However, samples of the second group (Fed SD showed lower values of both ultimate pH and water separation % using raw thigh meat. The effect of FD treatment on the meat composition appeared clearly especially on fat percentage content. In addition, meat samples obtained from chickens fed SD showed better significant values of the overall acceptability attribute. According to the current findings, sucrose could be an excellent alternative to oil in dietary broilers which improved the meat preservation bio-system, and post-mortem storage stability.

The process of chemical biotechnological processing of collagen-containing raw materials into functional components of feeds for effective pig rearing was studied. Protein components of feeds were obtained as a result of hydrolysis in the presence of lactic acid of the animal collagen from secondary raw materials, which comprised subcutaneous collagen (cuticle), skin and veined mass with tendons from cattle. For comparison, a method is described for preparing protein components of feeds by cultivating Lactobacillus plantarum. Analysis of the kinetic data of the conversion of a high-molecular collagen protein to an aminolyte polypeptide mixture showed the advantage of microbiological synthesis in obtaining a protein for feeds. Feed formulations have been developed to include the components obtained, and which result in high quality pork suitable for the production of quality meat products.

Kochlik, Bastian; Gerbracht, Christiana; Grune, Tilman

2018-01-01

Scope 3‐Methylhistidine (3‐MH) as a potential biomarker for muscle protein turnover is influenced by meat intake but data on the impact of meat on plasma 3‐MH are scarce. We determined the association of plasma 3‐MH, 1‐methylhistidine (1‐MH), and creatinine with dietary habits and assessed the impact of a single white meat intervention during a meat‐free period. Methods and results Plasma 3‐MH, 1‐MH, and creatinine concentrations of healthy young omnivores (n = 19) and vegetarians (n = 16) were analyzed together with data on anthropometry, body composition, grip strength, and nutrition. After baseline measurements omnivores adhered to a meat‐free diet for 6 days and received a defined administration of chicken breast on day four. At baseline, omnivores had higher plasma 3‐MH and 1‐MH concentrations than vegetarians. White meat administration led to a slight increase in plasma 3‐MH in omnivores. The elevated 3‐MH concentrations significantly declined within 24 h after white meat intake. Conclusion 1‐MH concentrations in plasma seem to be suitable to display (white) meat consumption and its influence on 3‐MH plasma concentration. 3‐MH in plasma may be used as a biomarker for muscle protein turnover if subjects have not consumed meat in the previous 24 h.

De Backer, Charlotte J S; Hudders, Liselot

2015-01-01

The aim of this work is to explore the relation between morality and diet choice by investigating how animal and human welfare attitudes and donation behaviors can predict a meat eating versus flexitarian versus vegetarian diet. The results of a survey study (N=299) show that animal health concerns (measured by the Animal Attitude Scale) can predict diet choice. Vegetarians are most concerned, while full-time meat eaters are least concerned, and the contrast between flexitarians and vegetarians is greater than the contrast between flexitarians and full-time meat eaters. With regards to human welfare (measured by the Moral Foundations Questionnaire), results show that attitudes towards human suffering set flexitarians apart from vegetarians and attitudes towards authority and respect distinguish between flexitarians and meat eaters. To conclude, results show that vegetarians donate more often to animal oriented charities than flexitarians and meat eaters, while no differences between the three diet groups occur for donations to human oriented charities.

Meat/meat alternatives (M/MA) are key sources of Fe, Zn and protein, but intake tends to be low in young children. Australian recommendations state that Fe-rich foods, including M/MA, should be the first complementary foods offered to infants. The present paper reports M/MA consumption of Australian infants and toddlers, compares intake with guidelines, and suggests strategies to enhance adherence to those guidelines. Mother-infant dyads recruited as part of the NOURISH and South Australian Infants Dietary Intake studies provided 3 d of intake data at three time points: Time 1 (T1) (n 482, mean age 5·5 (SD 1·1) months), Time 2 (T2) (n 600, mean age 14·0 (SD 1·2) months) and Time 3 (T3) (n 533, mean age 24 (SD 0·7) months). Of 170 infants consuming solids and aged greater than 6 months at T1, 50 (29%) consumed beef, lamb, veal (BLV) or pork on at least one of 3 d. Commercial infant foods containing BLV or poultry were the most common form of M/MA consumed at T1, whilst by T2 BLV mixed dishes (including pasta bolognaise) became more popular and remained so at T3. The processed M/MA increased in popularity over time, led by pork (including ham). The present study shows that M/MA are not being eaten by Australian infants or toddlers regularly enough; or in adequate quantities to meet recommendations; and that the form in which these foods are eaten can lead to smaller M/MA serve sizes and greater Na intake. Parents should be encouraged to offer M/MA in a recognisable form, as one of the first complementary foods, in order to increase acceptance at a later age.

Full Text Available The article is aimed at analyzing the condition, development specifics, concentration and competition in the global meat market. Both significance and role of meat in providing the food security has been substantiated. An analysis of the dynamics and structure (both geographical and commodity of production volumes, consumption, exports and imports of meat has been conducted. The major producers, consumers, exporters and importers of meat in the context of globalization have been identified. The country-based features, patterns of consumption and imports of meat have been characterized. On the basis of calculated five indicators of concentration (coefficient of concentration, the Herfindahl-Hirschman index, coefficient of relative concentration, dispersion of logarithms of market shares, index of the maximum share the features of competition in the global market of producers and consumers of meat have been determined.

Longissimus dorci (LD) samples of different origin (imported and domestic) with pre-treatments (imported meat stored at -18°C for 6months, domestic meat stored at -18°C for 10days, and domestic meat stored at 4°C for 24h) were cooked as barbacoa and frozen using two treatments (air blast and liquid immersion) and then evaluated after 30days of storage. The results showed that the origin and pre-treatment of meat affected L*, a*, instrumental texture and microstructure; that the storage time affected pH, aw, b* and microstructure; and that the freezing treatments did not affect the meat. Overall, the frozen cooked lamb dish barbacoa could present some problems at the conservation stage due to an increase in pH, aw and changes in microstructure; however, the physical traits (color and texture) remained mostly unchanged and depended more on the quality of the raw meat.

Pasteurization of milk ensures safety for human consumption by reducing the number of viable pathogenic bacteria. Although the public health benefits of pasteurization are well established, pro-raw milk advocate organizations continue to promote raw milk as "nature's perfect food." Advocacy groups' claims include statements that pasteurization destroys important vitamins and that raw milk consumption can prevent and treat allergies, cancer, and lactose intolerance. A systematic review and meta-analysis was completed to summarize available evidence for these selected claims. Forty studies assessing the effects of pasteurization on vitamin levels were found. Qualitatively, vitamins B12 and E decreased following pasteurization, and vitamin A increased. Random effects meta-analysis revealed no significant effect of pasteurization on vitamin B6 concentrations (standardized mean difference [SMD], -2.66; 95% confidence interval [CI], -5.40, 0.8; P = 0.06) but a decrease in concentrations of vitamins B1 (SMD, -1.77; 95% CI, -2.57, -0.96; P pasteurization on milk's nutritive value was minimal because many of these vitamins are naturally found in relatively low levels. However, milk is an important dietary source of vitamin B2, and the impact of heat treatment should be further considered. Raw milk consumption may have a protective association with allergy development (six studies), although this relationship may be potentially confounded by other farming-related factors. Raw milk consumption was not associated with cancer (two studies) or lactose intolerance (one study). Overall, these findings should be interpreted with caution given the poor quality of reported methodology in many of the included studies.

Consumers in the United States continue to eat raw or undercooked foods of animal origin despite public health warnings following several well-publicized outbreaks. We investigated an outbreak of Salmonella serotype Typhimurium infection in 158 patients in Wisconsin during the 1994 Christmas holiday period. To determine the vehicle and source of the outbreak, we conducted cohort and case-control studies, and environmental investigations in butcher shop A. Eating raw ground beef purchased from butcher shop A was the only item significantly associated with illness [cohort study: relative risk = 5.8, 95% confidence interval (CI) = 1.5-21.8; case control study: odds ratio = 46.2, 95% CI = 3.8-2751]. Inadequate cleaning and sanitization of the meat grinder in butcher shop A likely resulted in sustained contamination of ground beef during an 8-day interval. Consumer education, coupled with hazard reduction efforts at multiple stages in the food processing chain, will continue to play an important role in the control of foodborne illness.

In this study we analyzed the exudate of beef to evaluate its potential as non invasive sampling for nuclear magnetic resonance (NMR) based metabolomic analysis of meat samples. Exudate, as the natural juice from raw meat, is an easy to obtain matrix that it is usually collected in small amounts in commercial meat packages. Although meat exudate could provide complete and homogeneous metabolic information about the whole meat piece, this sample has been poorly studied. Exudates from 48 beef samples of different breeds, cattle and storage times have been studied by "1H NMR spectroscopy. The liquid exudate spectra were compared with those obtained by High Resolution Magic Angle Spinning (HRMAS) of the original meat pieces. The close correlation found between both spectra (>95% of coincident peaks in both registers; Spearman correlation coefficient = 0.945) lead us to propose the exudate as an excellent alternative analytical matrix with a view to apply meat metabolomics. 60 metabolites could be identified through the analysis of mono and bidimensional exudate spectra, 23 of them for the first time in NMR meat studies. The application of chemometric tools to analyze exudate dataset has revealed significant metabolite variations associated with meat aging. Hence, NMR based metabolomics have made it possible both to classify meat samples according to their storage time through Principal Component Analysis (PCA), and to predict that storage time through Partial Least Squares (PLS) regression. - Highlights: • NMR spectra from beef samples and their exudates are very strongly correlated. • 23 metabolites not reported in previous NMR meat studies have been identified. • Meat exudate NMR spectra allow monitoring of biochemical changes related to aging. • PCA of exudate NMR spectra classified meat samples by their storage time. • The aging of a meat sample can be predicted by PLS analysis of its exudate.

The camel is an excellent source of high quality meat and camel meat might be a potential alternative for beef. This study aimed to manipulate the raw camel meat for the production of stable and acceptable emulsion sausage, as well as to study the effect of cooking at different core temperatures on the tenderness, sensory quality and microstructure of produced sausage. Increasing the cooking temperature of sausages resulted in reduction of the shear force values from 2.67 kgf after cooking at 85 °C to 1.57 kgf after cooking at 105 °C. The sensory scores of sausages have been improved by increasing the cooking core temperature of meat batter. The light and scanning electron microscope micrographs revealed solubilisation of the high quantity of connective tissue of camel meat. High emulsion stability values for the camel meat batter associated with high values of water-holding capacity for raw camel meat and meat batter have been recorded. Stable and acceptable camel meat emulsion can be developed from camel meat. Increasing the cooking core temperature of meat batter improved the quality of produced sausages. Therefore, camel meat emulsion sausages might be a potential alternative for beef particularly in Asian and African countries. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

The aim of the study was to compare immunomagnetic separation (IMS) and conventional selective enrichment procedures using selenite cystine broth (SC) and Rappaport-Vassiliadis broth (RV) in 137 naturally contaminated food samples (69 raw pork sausages and 68 chicken meat). The utilization of SC or IMS appeared to be the most appropriate enrichment procedure: 15 out of 18 Salmonella-positive samples (83.3%) were detected by SC and 12 (66.7%) by IMS; RV yielded only seven positive isolations (38.9%). However, RV yielded the highest count of Salmonella colonies per plate and the lowest interference by competing organisms. IMS could become a reliable alternative to standard enrichment procedures and a combined IMS and selective enrichment broth could increase the chance of Salmonella recovery.

Full Text Available Tourism development launches growth of other complementary industries. River tourism, as a special selective tourism form, experiences intensive development, with an importance for all the regions through which the Danube, as an integral part of the Rhine - Main - Danube waterway, flows. During cruising, the largest consumption is achieved on the ship itself, where meat and meat products are an integral element of every meal and represent the most expensive component of the dish. The task of this paper is to analyse the consumption of meat and meat products on six tourist ships run by to 'Grand Circle Corporation' in 2013, in order to point out the possibility of supplying them with meat and meat products from sources in the territory where the ships sail. The paper presents the current suppliers and manufacturers of meat and meat products in Republic of Serbia that could supply the company 'Grand Circle Cruise Line' and other tourist ships that cruise on the Danube. Also, the research indicates that the export of meat products from the Republic Serbia could have a significant effect on improving the agricultural conditions and food production through increased competition, assuming the Serbian manufacturers supply most of tourist ships and not only the six ships analysed in this paper. Research results, specifically, point out the possibility of increasing export of poultry and beef if the potential demand of each of the eight companies with their 54 ships which operate tourist cruises on the Danube is taken into account. The data have been systematized, analysed and presented statistically in tables and graphs.

Full Text Available Background: To study prevalence of Campylobacter spp. in chicken and beef meat, and determine the drug susceptibility of strains, 450 samples in Tehran, Iran were investigated. Objectives: This study aimed to determine the prevalence and the antimicrobial resistance of entropathogenic Campylobacter strains ,especially C. jejuni isolated from raw chicken and beef meat in Tehran- Iran. Materials and Methods: Out of 250 chickens and 200 beef meats, 121(26.8 % contaminated cases with Campylobacter strains were isolated. Campylobacter was isolated from a significantly larger number of chickens (44% than beef meats (5.5 % (P < 0.05. Results: From all isolated Campylobacter organisms, 93 (76.8% species were identified as C. jejuni and 28 cases (23.1% as C. coli. Susceptibilities of 121 strains (93 C. jejuni and 28 C. coli were determined against 12 antimicrobial drugs using the disk agar diffusion method. Resistance to nalidixic acid (75% and ciprofloxacin (50% was an alarming finding, moreover, 32.6% of isolates was resistant to tetracycline, 10.8% to ampicillin, 29.3% to colisitin and 26.1% to amoxicillin. The highest sensitivity was seen to erythromycin (95 % and gentamicin (96%. Conclusions: These results showed that a high proportion of chicken and beef meat in Iran is contaminated with Campylobacter, particularly with Campylobacter jejuni. The high rate of contamination, especially chicken is a significant public health concern. Most of the isolates were resistant; therefore, human infection with Campylobacter spp. via consumption of these products is possible.

Prostate cancer (PC) is the most common male malignancy in the United States and disparities in risk exist among ethnic/racial groups. A high intake of well-done meat and the presence of the rapid NAT1 and slow NAT2 acetylator genotypes, as modifiers of the carcinogenic effect of heterocyclic amines, were hypothesized to increase PC risk and possibly explain these ethnic differences in risk. This study examined the associations between well-done (red) meat consumption, NAT1 and NAT2 acetylator genotypes, and PC risk among five ethnicities (African American, Native Hawaiian, Japanese American, Latino, and Caucasian) in a case-control study of PC nested within the Multiethnic Cohort study. Cases (n = 2,106) and controls (n = 2,063) were genotyped for eight single nucleotide polymorphisms in NAT1 and seven single nucleotide polymorphisms in NAT2 that characterized all common alleles for these genes. Well-done meat intake was computed based on responses to a detailed food frequency questionnaire including a question on meat preference. Conditional logistic regression was used in the analysis. There was no evidence of an increased risk associated with preference for well-done meat, intake of well-done meat, and NAT1 or NAT2 genotypes (jointly or separately). These results do not support the hypothesis that exposure to heterocyclic amines is associated with risk of PC. However, additional studies with more precise exposure measures are needed.

2015-03-01

Sister chromatid exchange (SCE) is a widely used sensitive cytogenetic biomarker of exposure to genotoxic and cancerogenic agents. Results of human monitoring studies and cytogenetic damage have revealed that biological effects of genotoxic exposures are influenced by confounding factors related to life-style. Vegetable and fruit consumption may play a role, but available results are not consistent. The purpose of the study was to investigate the effect of consumption of raw and cooked vegetables and fruits on SCE frequency. A total of 62 participants included colorectal cancer (CRC) patients, hospital-based controls and healthy laboratory workers. SCE frequency was assessed in blood lymphocytes. Frequency of vegetable and fruit consumption was gathered by structured semi-quantitative food frequency questionnaire. SCE frequency was lowest among hospital-based controls (4.4 ± 1.1), a bit higher in CRC patients (4.5 ± 1.0) and highest among laboratory workers (7.4 ± 1.2) (p consumption, but not so for intake of cooked vegetables and fruits. The results of the study have shown the beneficial effect of consumption of raw vegetables on disrupted replication of DNA measured by SCE frequency, implying protection against genotoxic agents. Further effort is required to verify the role of cooked vegetables and fruits.

Effect of Selected Alternative Fuels and Raw Materials on the Cement Clinker Quality

Directory of Open Access Journals (Sweden)

Strigáč Július

2015-11-01

Full Text Available The article deals with the study of the effects of alternative fuels and raw materials on the cement clinker quality. The clinker quality was expressed by the content of two principal minerals alite C3S and belite C2S. The additions of alternative fuels ashes and raw materials, in principle, always increased the belite content and conversely reduced the amount of alite. The alternative fuels with high ash content were used such as the meat-bone meal, sewage sludge from sewage treatment plants and paper sludge and the used alternative raw materials were metallurgical slags - granulated blastfurnace slag, air cooled blastfurnace slag and demetallized steel slag, fluidized bed combustion fly ash and waste glass. Meat-bone meal, sewage sludge from sewage treatment plants and paper sludge were evaluated as moderately suitable alternative fuels which can be added in the amounts of 2.8 wt. % addition of meat-bone meals ash, 3.64 wt. % addition of sewage sludge ash and 3.8 wt. % addition of paper sludge ash to the cement raw mixture. Demetallised steel slag is suitable for production of special sulphate resistant cement clinker for CEM I –SR cement with addition up to 5 wt. %. Granulated blastfurnace slag is a suitable alternative raw material with addition 4 wt. %. Air cooled blastfurnace slag is a suitable alternative raw material with addition 4.2 wt. %. Waste glass is not very appropriate alternative raw material with addition only 1.16 wt. %. Fluidized bed combustion fly ash appears not to be equally appropriate alternative raw material for cement clinker burning with less potential utilization in the cement industry and with addition 3.41 wt. %, which forms undesired anhydrite CaSO4 in the cement clinker.

Implications of domestic food practices for the presence of bioactive components in meats with special reference to meat-based functional foods.

Although an essential component of the diet, the consumption of meat is in question. Meat is a major source of beneficial compounds but it also contains other substances with negative health implications. Functional foods, which are leading trends in the food industry, constitute an excellent opportunity for the meat sector to improve healthier meat options. Most studies on meat-based functional foods have focused mainly on the application of different strategies (animal production practices and meat transformation systems) to improve (increase/reduce) the presence of bioactive (healthy/unhealthy) compounds; these have led to the development of numerous products, many of them by the meat industry. However, like other foods, after purchase meats undergo certain processes before they are consumed, and these affect their composition. Although domestic handling practices can significantly alter the make-up of the marketed product in terms of healthy/unhealthy compounds, there are very few studies on their consequences. This paper provides an overview of the influence of different domestic practices (from shopping to eating) habitually followed by consumers on the presence of, and consequently on the levels of exposure to, (healthy and unhealthy) food components associated with the consumption of meats, with special reference to meat-based functional foods.

Paediatric HUS Cases Related to the Consumption of Raw Milk Sold by Vending Machines in Italy: Quantitative Risk Assessment Based on Escherichia coli O157 Official Controls over 7 years.

A quantitative risk assessment (RA) was developed to estimate haemolytic-uremic syndrome (HUS) cases in paediatric population associated with the consumption of raw milk sold in vending machines in Italy. The historical national evolution of raw milk consumption phenomenon since 2008, when consumer interest started to grow, and after 7 years of marketing adjustment, is outlined. Exposure assessment was based on the official Shiga toxin-producing Escherichia coli O157:H7 (STEC) microbiological records of raw milk samples from vending machines monitored by the regional Veterinary Authorities from 2008 to 2014, microbial growth during storage, consumption frequency of raw milk, serving size, consumption preference and age of consumers. The differential risk considered milk handled under regulation conditions (4°C throughout all phases) and the worst time-temperature field handling conditions detected. In case of boiling milk before consumption, we assumed that the risk of HUS is fixed at zero. The model estimates clearly show that the public health significance of HUS cases due to raw milk STEC contamination depends on the current variability surrounding the risk profile of the food and the consumer behaviour has more impact than milk storage scenario. The estimated HUS cases predicted by our model are roughly in line with the effective STEC O157-associated HUS cases notified in Italy only when the proportion of consumers not boiling milk before consumption is assumed to be 1%. Raw milk consumption remains a source of E. coli O157:H7 for humans, but its overall relevance is likely to have subsided and significant caution should be exerted for temporal, geographical and consumers behaviour analysis. Health education programmes and regulatory actions are required to educate people, primarily children, on other STEC sources. © 2016 Blackwell Verlag GmbH.

Literature suggests that early exposure to the farming environment protects against atopy and asthma; few studies have examined pulmonary function. We evaluated associations between early-life farming exposures and pulmonary function in 3061 adults (mean age=63) from a US farming population using linear regression. Childhood raw milk consumption was associated with higher FEV 1 (β=49.5 mL, 95% CI 2.8 to 96.1 mL, p=0.04) and FVC (β=66.2 mL, 95% CI 13.2 to 119.1 mL, p=0.01). We did not find appreciable associations with other early-life farming exposures. We report a novel association between raw milk consumption and higher pulmonary function that lasts into older adulthood. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

EVALUATION OF ENERGY CONSUMPTION IN AGRO-INDUSTRIAL WASTEWATER TREATMENT PLANT

Directory of Open Access Journals (Sweden)

Wojciech Dąbrowski

2016-07-01

Full Text Available Energy consumption during waste water treatment is a very important factor affecting food industry plants. Apart from highly efficient treatment of dairy and meat sewage, a low energy consumption is required in order to lower its costs. During the research period parameters of raw and treated sewage were tested (BOD, COD, N-total, P-total. Also, the energy consumption from selected processes as well as total consumption were measured. Indicators of energy consumption per m3 and removed load were calculated. It was found that biological treatment and aeration played the main role in energy consumption in both objects. It was respectively 40 and 47% for Bielmlek and JBB plants. The second biggest energy consuming stage of treatment in both objects was sludge processing. Energy required to process excessive sludge equaled 30% of the total energy usage in both plants. Energy consumption factors related to hydraulic flow gave results in the range from 2,05 to 3,3 kWhm-3 and from 2,72 to 3,23 kWhm-3 for Bielmlek and JBB plants respectively. The research will be continued in order to optimize energy consumption while retaining high efficiency treatment in food industry WWTPs. Finally a mathematical model will be prepared for optimizing energy consumption in food industry WWTPs.

Supercritical fluid extraction of meat lipids: an alternative approach to the identification of irradiated meats

International Nuclear Information System (INIS)

Hampson, J.W.; Jones, K.C.; Foglia, T.A.; Kohout, K.M.

1996-01-01

Ionizing radiation is currently under study as an alternative method for extending the shelf life of meats and meat products. Accordingly, methods are needed to determine if a meat or meat product has been exposed to ionizing radiation. In this study, a method is described for the isolation and analysis of volatile hydrocarbons formed in meat lipids after exposure to ionizing radiation. The method is based on supercritical fluid extraction of the hydrocarbons from meat lipids and subsequent identification and quantitation of individual hydrocarbons by gas chromatography (GC) with a mass selection detector (MSD). Supercritical carbon dioxide at 175 bar and 40°C extracted the hydrocarbon fraction from total meat lipids within 20 min. The presence of radiolytic hydrocarbons, as determined by GC/MSD, was then correlated to the degree of irradiation of the meat from 0 to 10 kGy. Besides being faster, this method has the advantage of reduced solvent consumption when compared to current methods for determining if a meat or meat product has been irradiated

Profile and effects of consumer involvement in fresh meat.

Science.gov (United States)

Verbeke, Wim; Vackier, Isabelle

2004-05-01

This study investigates the profile and effects of consumer involvement in fresh meat as a product category based on cross-sectional data collected in Belgium. Analyses confirm that involvement in meat is a multidimensional construct including four facets: pleasure value, symbolic value, risk importance and risk probability. Four involvement-based meat consumer segments are identified: straightforward, cautious, indifferent, and concerned. Socio-demographic differences between the segments relate to gender, age and presence of children. The segments differ in terms of extensiveness of the decision-making process, impact and trust in information sources, levels of concern, price consciousness, claimed meat consumption, consumption intention, and preferred place of purchase. The two segments with a strong perception of meat risks constitute two-thirds of the market. They can be typified as cautious meat lovers versus concerned meat consumers. Efforts aiming at consumer reassurance through quality improvement, traceability, labelling or communication may gain effectiveness when targeted specifically to these two segments. Whereas straightforward meat lovers focus mainly on taste as the decisive criterion, indifferent consumers are strongly price oriented.

This article investigates the emergence of the Copenhagen slaughterhouse, called the Meat City, during the late nineteenth century. This slaughterhouse was a product of a number of heterogeneous components: industrialization and new infrastructures were important, but hygiene and the significance...... of Danish bacon exports also played a key role. In the Meat City, this created a distinction between rising production and consumption on the one hand, and the isolation and closure of the slaughtering facility on the other. This friction mirrored an ambivalent attitude towards meat in the urban space: one...... where consumers demanded more meat than ever before, while animals were being removed from the public eye. These contradictions, it is argued, illustrate and underline the change of the city towards a ‘post-domestic’ culture. The article employs a variety of sources, but primarily the Copenhagen...

Meat spoilage during distribution.

Nychas, George-John E; Skandamis, Panos N; Tassou, Chrysoula C; Koutsoumanis, Konstantinos P

2008-01-01

Meat spoilage during distribution can be considered as an ecological phenomenon that encompasses the changes of the available substrata (e.g., low molecular compounds), during the prevailing of a particular microbial association, the so-called specific spoilage organisms (SSO). In fact, spoilage of meat depends on an even smaller fraction of SSO, called ephemeral spoilage organisms (ESO). These ESO are the consequence of factors that dynamically persist or imposed during, e.g., processing, transportation and storage in the market. Meanwhile spoilage is a subjective judgment by the consumer, which may be influenced by cultural and economic considerations and background as well as by the sensory acuity of the individual and the intensity of the change. Indeed, when spoilage progresses, most consumers would agree that gross discoloration, strong off-odors, and the development of slime would constitute the main qualitative criteria for meat rejection. On the other hand, meat industry needs rapid analytical methods or tools for quantification of these indicators to determine the type of processing needed for their raw material and to predict remaining shelf life of their products. The need of an objective evaluation of meat spoilage is of great importance. The use of metabolomics as a potential tool for the evaluation of meat spoilage can be of great importance. The microbial association of meat should be monitored in parallel with the estimation of changes occurring in the production and/or assimilation of certain compounds would allow us to evaluate spoilage found or produced during the storage of meat under different temperatures as well as packaging conditions.

This study aimed to examine the effect of bird age on the contents of endogenous bioactive compounds, including carnosine, anserine, creatine, betaine, and carnitine, in meat from a certified meat-type commercial Korean native chicken strain (KNC; Woorimatdag). Additionally, the effects of the meat type (breast or leg meat) and the state of the meat (raw or cooked) were examined. Cocks of KNC were raised under similar standard commercial conditions at a commercial chicken farm. At various ages (10, 11, 12, 13, and 14 wk), breast and leg meats from a total of 10 birds from each age group were obtained. Raw and cooked meat samples were then prepared separately and analyzed for bioactive compounds. The age of the KNC had a significant effect only on the betaine content. The breast meat of KNC had higher amounts of carnosine and anserine but had lower amounts of betaine and carnitine than the leg meat (P cooking (P cooking, whereas breast meat showed almost complete retention of betaine and carnitine. The results of this study provide useful and rare information regarding the presence, amounts, and determinants of endogenous bioactive compounds in KNC meat, which can be useful for selection and breeding programs, and also for popularizing indigenous chicken meat. © 2014 Poultry Science Association Inc.

PRODUCTION AND SUPPLY BALANCE OF POULTRY MEAT IN CROATIA

Full Text Available Poultry meat is an important protein source in the human consumption. The main factors that have a positive effect on the development of the poultry industry are short production cycle, relatively low cost and the lack of religious restrictions on consumption. Chicken meat has the biggest share in the structure of poultry meat. The paper objective was to calculate the level of self-sufficiency degree in poultry meat in Croatia in the period from 2000 to 2012 and the degree of self-sufficiency in 2016 based on the results obtained. The method of balancing was used for calculation of self-sufficiency degree. The degree of self-sufficiency in the production of poultry meat in Croatia is higher than in other types of meat being between 80 and 90%. However, further decrease is expected and in 2016 domestic production would meet 81.17% of the domestic needs.

Red and processed meat (RPM) intake varies widely globally. In some high-income countries (HIC) the last decade has witnessed an overall decline or stabilisation in the consumption of RPM, in contrast to emerging economies where its consumption continues to increase with rising income and rapid urbanisation. The production and consumption of RPM have become major concerns regarding the environmental impacts of livestock in particular, but also because of associations between high RPM consumption and diet-related non-communicable disease. Therefore, it is important to identify socioeconomic and demographic drivers of the consumption of RPM. This paper explores how consumption of RPM differs with age, gender, socioeconomic status and in different global contexts. There are some key socioeconomic and demographic patterns in RPM consumption. Men tend to consume RPM more often and in higher quantities, and there is evidence of a social gradient in HIC, with lower socioeconomic groups consuming RPM more often and in larger quantities. Patterns for consumption with age are less clear cut. It is apparent that consumers in HIC are still consuming high levels of RPM, although the downward shifts in some socioeconomic and demographic groups is encouraging and suggests that strategies could be developed to engage those consumers identified as high RPM consumers. In low- and middle-income countries, RPM consumption is rising, especially in China and Brazil, and in urban areas. Ways of encouraging populations to maintain their traditional healthy eating patterns need to be found in low- and middle-income countries, which will have health, environmental and economic co-benefits.

Background: Meat cooking conditions in in vitro and in vivo models have been shown to influence the rate of protein digestion, which is known to affect postprandial protein metabolism in the elderly. Objective: The present study was conducted to demonstrate the effect of cooking conditions on meat protein assimilation in the elderly. We used a single-meal protocol to assess the meat protein absorption rate and estimate postprandial meat protein utilization in elderly subjects. Design: The study recruited 10 elderly volunteers aged 70-82 y. Each received, on 2 separate occasions, a test meal exclusively composed of intrinsically 15 N-labeled bovine meat (30 g protein), cooked at 55°C for 5 min [rare meat (RM)] or at 90°C for 30 min [fully cooked meat (FCM)], and minced. Whole-body fluxes of leucine, before and after the meal, were determined with the use of a [1- 13 C]leucine intravenous infusion. Meat protein absorption was recorded with the use of 15 N enrichment of amino acids. Results: Postprandial time course observations showed a lower concentration in the plasma of indispensable amino acids ( P meat leucine in the plasma ( P meat nitrogen to plasma amino acid nitrogen ( P meat amino acids with RM than with FCM. This was associated with decreased postprandial whole-body protein synthesis with RM than with FCM (40% compared with 56% of leucine intake, respectively; P meat cooking conditions have little effect on postprandial protein utilization in young adults, the present work showed that the bioavailability and assimilation of meat amino acids in the elderly is lower when meat is poorly cooked. In view to preventing sarcopenia, elderly subjects should be advised to favor the consumption of well-cooked meat.

The health-conscious consumers are in search of nutritious and convenient food item which can be best suited in their busy life. The vegetarianism is the key for the search of such food which resembles the meat in respect of nutrition and sensory characters, but not of animal origin and contains vegetable or its modified form, this is the point when meat analog evolved out and gets shape. The consumers gets full satisfaction by consumption of meat analog due to its typical meaty texture, appearance and the flavor which are being imparted during the skilled production of meat analog. The supplement of protein in vegetarian diet through meat alike food can be fulfilled by incorporating protein-rich vegetative food grade materials in meat analog and by adopting proper technological process which can promote the proper fabrication of meat analog with acceptable meat like texture, appearance, flavor, etc. The easily available vegetables, cereals, and pulses in India have great advantages and prospects to be used in food products and it can improve the nutritional and functional characters of the food items. The various form and functional characters of food items are available world over and attracts the meat technologists and the food processors to bring some innovativeness in meat analog and its presentation and marketability so that the acceptability of meat analog can be overgrown by the consumers.

It is essential to isolate high-quality DNA from muscle tissue for PCR-based applications in traceability of animal origin. We wished to examine the impact of cooking meat to a range of core temperatures on the quality and quantity of subsequently isolated genomic (specifically, nuclear) DNA. Triplicate steak samples were cooked in a water bath (100 degrees C) until their final internal temperature was 75, 80, 85, 90, 95, or 100 degrees C, and DNA was extracted. Deoxyribonucleic acid quantity was significantly reduced in cooked meat samples compared with raw (6.5 vs. 56.6 ng/microL; P 800 bp) were observed only when using DNA from raw meat and steak cooked to lower core temperatures. Small amplicons (food authentication, it is less abundant, and results suggest that analyses should be designed to use small amplicon sizes for meat cooked to high core temperatures.

Are the Dietary Guidelines for Meat, Fat, Fruit and Vegetable Consumption Appropriate for Environmental Sustainability? A Review of the Literature

Science.gov (United States)

Reynolds, Christian John; Buckley, Jonathan David; Weinstein, Philip; Boland, John

2014-01-01

This paper reviews the current literature around the environmental impacts of dietary recommendations. The focus of the review is on collating evidence relating to environmental impacts of the dietary advice found in the World Health Organisation guidelines, and environmental impact literature: reducing the consumption of fat, reducing the consumption of meat-based protein and animal-based foods, and increasing the consumption of fruit and vegetables. The environmental impact of reducing dietary fat intake is unclear, although reducing consumption of the food category of edible fats and oils appears to have little impact. However most, but not all, studies support environmental benefits of a reduced consumption of animal-based foods and increased consumption of fruit and vegetables. In general, it appears that adhering to dietary guidelines reduces impact on the environment, but further study is required to examine the environmental impacts of animal-based foods, and fruit and vegetable intake in depth.

2010-03-01

The influence of vitamin E and selenomethionine (SeMet) on lipid oxidation in frozen-raw and cooked omega-3 enriched dark chicken meat was evaluated. Feed was supplemented with 2 levels of vitamin E (250 and 50 IU/kg of feed) and selenium (0.1 mg of sodium selenite/kg of feed and 0.3 mg of SeMet/kg of feed). An extruded linseed product was used as the alpha-linolenic acid source. Fatty acid (FA) profile, oxysterols, and thiobarbituric reactive acid substances (TBARs) were analyzed in frozen-raw, boiled, pan-fried, and roasted meat. After 6 mo of storage, oxysterols in frozen-raw meat remained stable with either high or low levels of dietary antioxidants. During cooking, high levels of vitamin E reduced oxysterol formation, whereas high levels of SeMet were inconsistent and even increased oxysterols during roasting. TBARs in frozen-raw meat stored for 6 mo were inhibited by high levels of either antioxidant. Conversely, no protective effect during cooking was observed at this time of storage. After 12 mo at -30 degrees C no antioxidant protection was observed.

Dietary lipids are one of the most effective stimulators of carotenoid absorption, but very limited data exist on the impact of endogenous food sources of lipids to enhance carotenoid absorption. The co-consumption of whole egg with carotenoid-rich foods may increase overall carotenoid absorption via lipid-rich egg yolk. We designed this study to assess the effects of egg consumption on carotenoid absorption from a carotenoid-rich, raw mixed-vegetable salad. Healthy young men (n = 16) consumed the same salad (all served with 3 g canola oil) with no egg (control), 75 g scrambled whole eggs (1.5 eggs) [low egg (LE)], and 150 g scrambled whole eggs (3 eggs) [high egg (HE)] (a randomized crossover design). Control, LE, and HE meals contained 23 mg, 23.4 mg (0.4 mg from eggs), and 23.8 mg (0.8 mg from eggs) total carotenoids and 3 g, 10.5 g (7.5 g from eggs), and 18 g (15 g from eggs) total lipids, respectively. Blood was collected hourly for 10 h, and the triacylglycerol-rich lipoprotein (TRL) fraction was isolated. Total and individual carotenoid contents, including lutein, zeaxanthin , α-carotene, β-carotene, and lycopene in TRL were analyzed, and composite areas under the curve (AUCs) were calculated. The total mean (±SE) carotenoid AUC0-10h in TRL was higher for the HE meal than for LE and control meals [125.7 ± 19.4(a) compared with 44.8 ± 9.2(b) compared with 14.9 ± 5.2(b) nmol/L · 10 h, respectively (values without a common superscript letter differ); P eggs, including α-carotene, β-carotene, and lycopene, increased 3-8-fold (P cooked whole eggs is an effective way to enhance carotenoid absorption from other carotenoid-rich foods such as a raw mixed-vegetable salad.

Full Text Available Six focus groups were conducted with each having ten people who attend different Islamic Centers in Ohio. The objective of the focus groups was to understand Halal meat purchase patterns and consumption patterns of the Moslem population with special attention to goat. The Ohio State University Extension personnel are utilizing these results to work with meat goat producers to understand and meet the requirements of the Halal meat market.  Participants discussed the Zabiha approach to slaughtering animals as the most merciful by causing the least pain. Many participants noted they had no way of knowing where the animal  came from and this held tremendous concerns relative to the feeding of animal by-products, use of hormones, and adulteration with pork. These trust concerns led to decisions about where to purchase their meat with 72% purchasing from a Moslem owned retail store. Only 13% purchased from a large grocery and 8% direct from a farmer.   Participants indicated their consumption patterns according to weekly, seasonal, and holiday use in addition to variations according to their personal geographic origin. The average meat purchase was 23 pounds with an average occurrence of 12.5 times per annum.  Purchasing trends indicated that 78% prefer lean over marbled cuts. Nearly 86% prefer fresh over frozen goat meat and nearly a third responded that they would pay more for fresh. Intact males were preferred by 42% of the respondents. Preferences for meat goat cuts were: Leg (71%, Chops (42%, Shoulder (24%, Breast (7%. Nearly a third indicated they also want the kidneys, heart, or head. Demographic shifts in the United States indicate that there are almost 53 million people who have a preference for goat meat. There are 2.4 million goats in the US according to the 2007 Agricultural Statistics. Based on consumption trends of this study, goat demand exceeds inventory by 160%.

While there are persistent rumors that the consumption of goat meat dishes increases blood pressure, there is no scientific evidence to support this. Two experiments were conducted to clarify whether or not blood pressure increases in conjunction with the consumption of goat meat dishes. In experiment 1, 24 Dahl/Iwai rats (15 weeks old, body weight 309.3±11.1 g) were evenly separated into 4 groups. The control group (CP) was fed a diet containing 20% chicken and 0.3% salt on a dry matter basis. The goat meat group (GM) was fed a diet containing 20% goat meat and 0.3% salt. The goat meat/salt group (GS) was fed a diet containing 20% goat meant and 3% to 4% salt. The Okinawan mugwort (Artemisia Princeps Pampan)/salt group (GY) was fed a diet containing 20% goat meat, 3% to 4% salt and 5% of freeze-dried mugwort powder. The experiment 1 ran for a period of 14 weeks during which time the blood pressure of the animals was recorded. The GS, and GY groups consumed significantly more water (pgoat meat does not cause increased blood pressure, rather the large amount of salt used in the preparation of goat meat dishes is responsible for the increase in blood pressure.

Meat slaughter establishments use a multipronged approach to ensure beef and pork products are safe for human consumption. To determine the approaches most commonly used, we conducted a national survey of federally inspected meat slaughter and processing establishments (376 completed surveys, 66% response rate) in 2015. We compared the results with a survey that was conducted in 2005, albeit of potentially different establishments, by using a similar questionnaire and similar data collection methods, thus allowing for an evaluation of trends in food safety practices over time. The use of some food safety practices has increased over the 10-yr time period, whereas others remained the same or decreased. For example, the use of chemical sanitizers or hot water for food contact surfaces and tools increased from 51 to 93%. As another example, microbiological testing of raw meat after fabrication, in addition to that required by regulation, increased from 50 to 72%. However, the use of organic acid rinse on carcasses in the slaughter area remained the same, at 66% of establishments. Written policies and procedures to control the use of hazardous chemicals decreased from 75 to 65% of establishments. The survey findings can be used to characterize food safety practices and technologies in the meat slaughter and processing industry and identify areas for improvement.

Full Text Available This study presents the evolution of global market of meat in 2007-2011 and has been possible because the authors used an important set of indicators, namely: livestock, achieved production, imports, exports, trade balance, price etc. The data used in this work was provided by the following institutions accredited for collecting and processing statistical data: National Institute of Statistics, EUROSTAT, FAOSTAT, FAPRI and USDA. The analysis global market of meat is primarily a quantitative analysis. In the period which is analysed, the demand, the production, the imports, the exports and the prices have evolved differently, especially meat categories, so all these indicators have influenced global market of meat. In mainly, the meat consumption is influenced by the pattern of food consumption and price level. In the future, expect a increase prices, which is based on increasing production costs. Therefore, first it is necessary to adopt measures to support the farmers.

2014-06-01

This article analyzed the demand for meats at household level over the past decade in Uruguay, a country that exhibits a very high per capita consumption of these products. In particular, the consumption of beef is one of the highest in the world and only comparable to Argentina. The analysis involved a two-step estimation of an incomplete system of censored demand equations using household data from the last available national income and expenditure survey (2005/06). Thirteen meat products were included in the analysis: six broad beef products (de boned hindquarter cuts, bone-in hindquarter cuts, ground beef, rib plate, bone-in forequarter cuts, and other beef cuts), four products from other meats (sheep, pork, poultry, and fish), and three generic mixed-meat products. A complete set of short-term income, own-price and cross-price elasticities were computed and reported along with their 90% confidence intervals (CI). The results were consistent with both economic theory and empirical evidence as well as with the expected behavior, considering the relevance of these products, particularly beef, in the diet of Uruguayan consumers. All meat items were necessary goods and evidenced income-inelastic responses, which was expected given their high consumption level. All meats behaved as normal goods although exhibiting different reactions to changes in price. In general, beef cuts were more price elastic than other more broadly defined products. The more specific and dis aggregated the meat product the higher its corresponding direct price elasticity. The complement/substitute relationships found in this study were highly depended on the specific product combinations. (Author)

Full Text Available The modern stage of the agro-industrial complex is characterized by an increasing complexity, intensification of technological processes of complex processing of materials of animal origin also the need for a systematic analysis of the variety of determining factors and relationships between them, complexity of the objective function of product quality and severe restrictions on technological regimes. One of the main tasks that face the employees of the enterprises of the agro-industrial complex, which are engaged in processing biotechnological raw materials, is the further organizational improvement of work at all stages of the food chain, besides an increase in the production volume. The meat industry as a part of the agro-industrial complex has to use the biological raw materials with maximum efficiency, while reducing and even eliminating losses at all stages of processing; rationally use raw material when selecting a type of processing products; steadily increase quality, biological and food value of products; broaden the assortment of manufactured products in order to satisfy increasing consumer requirements and extend the market for their realization in the conditions of uncertainty of external environment, due to the uneven receipt of raw materials, variations in its properties and parameters, limited time sales and fluctuations in demand for products. The challenges facing the meat industry cannot be solved without changes to the strategy for scientific and technological development of the industry. To achieve these tasks, it is necessary to use the prediction as a method of constant improvement of all technological processes and their performance under the rational and optimal regimes, while constantly controlling quality of raw material, semi-prepared products and finished products at all stages of the technological processing by the physico-chemical, physico-mechanical (rheological, microbiological and organoleptic methods.

The effect of pork irradiated with doses up to 10 kGy on meat emulsions formulated with carboxy methyl cellulose (CMC) was investigated. Raw pork was vacuums packaged at a thickness of 2.0 cm and irradiated by X-ray linear accelerator (15 kW, 5 MeV). The emulsion had higher lightness, myofibrillar protein solubility, total protein solubility, and apparent viscosity with increasing doses, whereas cooking loss, total expressible fluid separation, and hardness decreased. There were no significant differences in fat separation, sarcoplasmic protein solubility, springiness, and cohesiveness. Our results indicated that it is treatment by ionizing radiation which causes the effects the physicochemical properties of the final raw meat product.

Understanding Urban Demand for Wild Meat in Vietnam: Implications for Conservation Actions.

Directory of Open Access Journals (Sweden)

Rachel Shairp

Full Text Available Vietnam is a significant consumer of wildlife, particularly wild meat, in urban restaurant settings. To meet this demand, poaching of wildlife is widespread, threatening regional and international biodiversity. Previous interventions to tackle illegal and potentially unsustainable consumption of wild meat in Vietnam have generally focused on limiting supply. While critical, they have been impeded by a lack of resources, the presence of increasingly organised criminal networks and corruption. Attention is, therefore, turning to the consumer, but a paucity of research investigating consumer demand for wild meat will impede the creation of effective consumer-centred interventions. Here we used a mixed-methods research approach comprising a hypothetical choice modelling survey and qualitative interviews to explore the drivers of wild meat consumption and consumer preferences among residents of Ho Chi Minh City, Vietnam. Our findings indicate that demand for wild meat is heterogeneous and highly context specific. Wild-sourced, rare, and expensive wild meat-types are eaten by those situated towards the top of the societal hierarchy to convey wealth and status and are commonly consumed in lucrative business contexts. Cheaper, legal and farmed substitutes for wild-sourced meats are also consumed, but typically in more casual consumption or social drinking settings. We explore the implications of our results for current conservation interventions in Vietnam that attempt to tackle illegal and potentially unsustainable trade in and consumption of wild meat and detail how our research informs future consumer-centric conservation actions.

Cheaper, legal and farmed substitutes for wild-sourced meats are also consumed, but typically in more casual consumption or social drinking settings. We explore the implications of our results for current conservation interventions in Vietnam that attempt to tackle illegal and potentially unsustainable trade in and consumption of wild meat and detail how our research informs future consumer-centric conservation actions.

This study was conducted to investigate the effects of raw material extrusion and steam conditioning on feed pellet quality and nutrient digestibility of growing meat rabbits, in order to determine appropriate rabbit feed processing methods and processing parameters. In Exp. 1, an orthogonal design was adopted. Barrel temperature, material moisture content and feed rate were selected as test factors, and acid detergent fiber (ADF) content was selected as an evaluation index to research the optimum extrusion parameters. In Exp. 2, a two-factor design was adopted. Four kinds of rabbit feeds were processed and raw material extrusion adopted optimum extrusion parameters of Exp. 1. A total of 40 healthy and 42-day-old rabbits with similar weight were used in a randomized design, which consisted of 4 groups and 10 replicates in each group (1 rabbits in each replicate). The adaptation period lasted for 7 d, and the digestion trial lasted for 4 d. The results showed as follows: 1) ADF was significantly affected by barrel temperature ( P  digestibility of dry matter and total energy ( P  digestibility of crude fiber (CF), ADF and NDF ( P  digestibility of rabbit feed. Thus, using extrusion and steam conditioning technology at the same time in the weaning rabbits feed processing can improve the pellet quality and nutrient apparent digestibility of rabbit feed.

Salmonella is among the most important food borne pathogens worldwide contaminating a wide range of animal products including meat products. Human illnesses due to this pathogen are attributed to poor biosecurity in production, improper processing and handling of meat and meat products....... This is more likely where surveillance and regulatory control is weak. There is however limited information on the occurrence of these pathogens in foods in Nigeria. The extent of contamination of retail-beef and related meat products with Salmonellae in Zaria was evaluated. A total of 435 retailed beef...... and related meat products consisting of muscle meat, offal and processed meat products were tested for the presence of Salmonella species. Sample types included raw meat, ‘suya’ (roasted meat), ‘balangu’ (barbequed meat), ‘Kilishi’ (spiced sun dried meat) and ‘dambu’ (shredded fried meat). Samples were...

Diverticulitis is a common disease with a substantial clinical and economic burden. Besides dietary fibre, the role of other foods in the prevention of diverticulitis is underexplored. We prospectively examined the association between consumption of meat (total red meat, red unprocessed meat, red processed meat, poultry and fish) with risk of incident diverticulitis among 46 461 men enrolled in the Health Professionals Follow-Up Study (1986-2012). Cox proportional hazards models were used to compute relative risks (RRs) and 95% CIs. During 651 970 person-years of follow-up, we documented 764 cases of incident diverticulitis. Compared with men in the lowest quintile (Q1) of total red meat consumption, men in the highest quintile (Q5) had a multivariable RR of 1.58 (95% CI 1.19 to 2.11; p for trend=0.01). The increase in risk was non-linear, plateauing after six servings per week (p for non-linearity=0.002). The association was stronger for unprocessed red meat (RR for Q5 vs Q1: 1.51; 95% CI 1.12 to 2.03; p for trend=0.03) than for processed red meat (RR for Q5 vs Q1: 1.03; 95% CI 0.78 to 1.35; p for trend=0.26). Higher consumption of poultry or fish was not associated with risk of diverticulitis. However, the substitution of poultry or fish for one serving of unprocessed red meat per day was associated with a decrease in risk of diverticulitis (multivariable RR 0.80; 95% CI 0.63 to 0.99). Red meat intake, particularly unprocessed red meat, was associated with an increased risk of diverticulitis. The findings provide practical dietary guidance for patients at risk of diverticulitis.

The purpose of this study was to determine the prevalence of Campylobacter in fresh vegetables and fruits at retail level in the Netherlands, and to estimate its implications on the importance of vegetables and fruits as risk factor for campylobacteriosis. Thirteen of the 5640 vegetable and fruit samples were Campylobacter positive, resulting in a prevalence of 0.23% (95% confidence interval (Cl): 0.12-0.39%). The prevalence of packaged products (0.36%, 95% Cl: 0.17-0.66) was significantly higher than of unpackaged products (0.07; 95% Cl: 0.01-0.27). No statistical differences were found between seasons. Combining the mean prevalence found in this study with data on the consumption of vegetables and fruits, an exposure of 0.0048 campylobacters ingested per person per day in the Netherlands by transmission via vegetables and fruits, was calculated. This exposure, as input in a Beta-Poisson dose-response model, resulted in an estimated number of 5.3×10⁵ cases of infection with Campylobacter per year for the whole Dutch population. This constitutes the consumption of raw vegetables and fruits, especially when packaged, to be a risk factor for Campylobacter infections. Copyright © 2010 Elsevier B.V. All rights reserved.

[Instinct therapy--raw food with meat with exclusion of milk products. Report No. 16].

Science.gov (United States)

Jallut, O

1989-06-13

Instinct therapy is a diet consisting exclusively of food in its natural form, which has not been subjected to cooking, preserving or seasoning. Dairy products are forbidden. Indications are numerous and rather imprecise including especially cancer. Burger developed Instinct therapy in 1964 as a diet according to his own philosophy. 1980 he left Switzerland because the practice of "metasexuality" had caused him problems with the law. He founded a school of Instinct therapy in 1982 in France and published his book "La guerre du cru" (The Raw Food Fight) in 1985. In Switzerland, Besuchet took on the teaching of Burger in 1978 and was very active in giving lectures. He died in June 1985 of mediastinal cancer. According to Burger, man originally ate raw food and his instinct has not evolved since those pre-historic times, but has been "artificially modified" by cooked food and the consumption of non-human milk. If man could re-develop his natural instinct and eat only fresh food, which is not prepared in any way, he could solve his health problems and restore defenses against diseases such that these could become beneficial. Cooked food, milk and cereals are thought to be the cause of cancer but instinctive eating would help to avoid or to cure cancer. No preclinical or clinical trials have been carried out. The theories of Burger and Besuchet are based on unverifiable personal experiences.

Radomyski, T; Niewiarowicz, A

1987-03-01

A quality evaluation was made of frankfurter-type sausages made from hand and mechanically deboned meat from various parts of turkey carcasses. The results led to the conclusions that despite some differences in objective measurements of the sausage quality, mechanically deboned turkey meat can be considered as an exclusive meat raw material for the production of frankfurter-type sausages. The quality of sausages from mechanically deboned turkey meat from wings and frames with skin was the least satisfactory.

Cahyadi, M.; Puruhita; Barido, F. H.; Hertanto, B. S.

2018-01-01

Polymerase chain reaction (PCR) is a molecular technique that widely used in agriculture area including species identification in animal-based products for halalness and food safety reasons. Amplification of DNA using PCR needs a primer pair (forward and reverse primers) to isolate specific DNA fragment in the genome. This objective of this study was to design specific primer from mitochondrial 12S rRNA region for species identification in raw beef, pork and chicken meat. Three published sequences, HQ184045, JN601075, and KT626857, were downloaded from National Center for Biotechnology Information (NCBI) website. Furthermore, those reference sequences were used to design specific primer for bovine, pig, and chicken species using primer3 v.0.4.0. A total of 15 primer pairs were picked up from primer3 software. Of these, an universal forward primer and three reverse primers which are specific for bovine, pig, and chicken species were selected to be optimized using multiplex-PCR technique. The selected primers were namely UNIF (5’-ACC GCG GTC ATA CGA TTA AC-3’), SPR (5’-AGT GCG TCG GCT ATT GTA GG-3’), BBR (5’-GAA TTG GCA AGG GTT GGT AA-3’), and AR (5’-CGG TAT GTA CGT GCC TCA GA-3’). In addition, the PCR products were visualized using 2% agarose gels under the UV light and sequenced to be aligned with reference sequences using Clustal Omega. The result showed that those primers were specifically amplified mitochondrial 12S rRNA regions from bovine, pig, and chicken using PCR. It was indicated by the existence of 155, 357, and 611 bp of DNA bands for bovine, pig, and chicken species, respectively. Moreover, sequence analysis revealed that our sequences were identically similar with reference sequences. It can be concluded that mitochondrial 12S rRNA may be used as a genetic marker for species identification in meat products.

Full Text Available A study was conducted to investigate the acceptability and preference of meat in Harar and Haramaya towns. The study was carried out from January to March, 2012. One hundred twenty (120 questionnaires were randomly distributed, completed and retrieved for analysis. The results showed that gender had no effect on livestock meat consumption. However, religious had impact on the types of meat consumption. Accordingly, pork was not consumed by both Muslim and Christian, camel meat was consumed by Muslim. Majority of consumers had prefer chicken, beef, and chevon meat as their first choice followed by mutton as compared to other meat. In addition, the study showed a high level of acceptability for the meat of middle aged than old aged. Lean and red color meat got highest acceptability by majority of the consumers than fatty and white meat. The result confirmed that religious and socio-cultural taboos as the major variables that would affect meat preference and consumption of a population in the study area. This study suggested that current preference trend of consumers were not inclusive in that some potential meat animals were hardly utilized or totally ignored from the dish. Therefore, professionals and other stakeholders should made intervention and promote widely utilization of this species to meet animal protein requirement of the community.

Eating green. Consumers' willingness to adopt ecological food consumption behaviors.

Science.gov (United States)

Tobler, Christina; Visschers, Vivianne H M; Siegrist, Michael

2011-12-01

Food consumption is associated with various environmental impacts, and consumers' food choices therefore represent important environmental decisions. In a large-scale survey, we examined consumers' beliefs about ecological food consumption and their willingness to adopt such behaviors. Additionally, we investigated in more detail how different motives and food-related attitudes influenced consumers' willingness to reduce meat consumption and to buy seasonal fruits and vegetables. We found consumers believed avoiding excessive packaging had the strongest impact on the environment, whereas they rated purchasing organic food and reducing meat consumption as least environmentally beneficial. Similarly, respondents appeared to be most unwilling to reduce meat consumption and purchase organic food. Taste and environmental motives influenced consumers' willingness to eat seasonal fruits and vegetables, whereas preparedness to reduce meat consumption was influenced by health and ethical motives. Women and respondents who preferred natural foods were more willing to adopt ecological food consumption patterns. Copyright © 2011 Elsevier Ltd. All rights reserved.

Detection of species fraud in meat products is important for consumer protection and food industries. A molecular technique such as PCR method for detection of beef, sheep, pork, chicken, donkey, and horse meats in food products was established. The purpose of this study was to identification of fraud and adulteration in industrial meat products by PCR-RFLP assay in Iran. In present study, 224 meat products include 68 sausages, 48 frankfurters, 55 hamburgers, 33 hams and 20 cold cut meats were collected from different companies and food markets in Iran. Genomic DNA was extracted and PCR was performed for gene amplification of meat species using specific oligonucleotid primers. Raw meat samples are served as the positive control. For differentiation between donkey's and horse's meat, the mitochondrial DNA segment (cytochrome-b gene) was amplified and products were digested with AluI restriction enzyme. Results showed that 6 of 68 fermented sausages (8.82%), 4 of 48 frankfurters (8.33%), 4 of 55 hamburgers (7.27%), 2 of 33 hams (6.6%), and 1 of 20 cold cut meat (5%) were found to contain Haram (unlawful or prohibited) meat. These results indicate that 7.58% of the total samples were not containing Halal (lawful or permitted) meat and have another meat. These findings showed that molecular methods such as PCR and PCR-RFLP are potentially reliable techniques for detection of meat type in meat products for Halal authentication.

Global environmental challenges require changes in both the production and the consumption of goods. In this paper we analyse how consumers perceive the high environmental burden of meat. We analysed consumer environmental consciousness, including problem awareness and a support to action dimensions, latter including perceived self-efficacy as well as solutions to problems. The solutions were positioned on a continuum from increasing the efficiency of production to discussing sufficiency levels in consumption practices (techno-optimism, local meat, organic meat and meat reduction, respectively). We used a statistically representative survey sample (n = 1890) from the population of Finland and cluster analysis to explore differences among consumers. The analysis revealed that most Finns seem to be rather unsure of the study topic. At the same time they tend to have a comparably high level of self-efficacy (55 per cent of respondents) and endorsement of particularly local meat solution type (55%), followed by organic meat (35%), meat reduction (25%) and techno-optimism (15%), though the neutral stand was the most common one across the data. We also identified six consumer groups that reveal not only a high number of Highly unsure consumers (40%), but also some Rather conscious (20%) and a relatively small number of Highly conscious (8%). In addition, there were also easily observable groups of Careless conscious (14%), Rather unsure (9%) and Resistant (8%). The results highlight the need for a multitude of political actions to guide meat consumption, as there are groups that may benefit from practical tools for making dietary changes as well as groups in need for more comprehensive selection of measures, including environmental information.

Di Giuseppe, Antonella M A; Giarretta, Nicola; Lippert, Martina; Severino, Valeria; Di Maro, Antimo

2015-02-15

In 2013, following the scandal of the presence of undeclared horse meat in various processed beef products across the Europe, several researches have been undertaken for the safety of consumer health. In this framework, an improved UPLC separation method has been developed to detect the presence of horse myoglobin in raw meat samples. The separation of both horse and beef myoglobins was achieved in only seven minutes. The methodology was improved by preparing mixtures with different composition percentages of horse and beef meat. By using myoglobin as marker, low amounts (0.50mg/0.50g, w/w; ∼0.1%) of horse meat can be detected and quantified in minced raw meat samples with high reproducibility and sensitivity, thus offering a valid alternative to conventional PCR techniques.

Few data, with conflicting findings, are available linking red meat consumption to indicators of insulin resistance and endothelial dysfunction. This study aimed to investigate the association of red meat consumption with insulin resistance and endothelial dysfunction among a sample of female nurses in Isfahan, Iran. This cross-sectional study was carried out among 420 female nurses who were selected by a multistage cluster random sampling method. Usual dietary intakes were assessed using a validated food frequency questionnaire. Red meat intake was calculated by summing up the consumption of all kinds of red meat in foods and processed meat in sausages and fast foods. To measure serum concentrations of adhesion molecules and glycemic indexes, a fasting blood sample was taken. After adjustment for potential confounders, high red meat intake was significantly associated with higher fasting plasma glucose, homeostasis model assessment of insulin resistance, and lower quantitative insulin sensitivity check index. Although high red meat intake was significantly associated with higher serum insulin levels and lower homeostasis model assessment of beta-cell function in the crude model, after controlling for BMI, the association was no longer significant. Red meat consumption was associated with high concentrations of E-selectin, soluble vascular cell adhesion molecule-1 (sVCAM-1), and soluble intercellular adhesion molecule-1 (sICAM-1) after adjustment for different potential confounders. We found that increased red meat intake was associated with high concentrations of plasma endothelial dysfunction biomarkers and abnormal glucose homeostasis among Iranian women. Prospective studies are required to confirm these findings. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Full Text Available This study was developed in order to evaluate two alternatives for the control of Listeria monocytogenes in raw bovine meat pieces, both based on the use of Thymus vulgaris and Rosmarinus officinalis essential oils (EOs. The antilisterial activity of different concentrations of the EOs was tested in vitro using agar dilution and disk volatilization techniques. In addition, L. monocytogenes was inoculated in meat pieces, which were submerged in edible gelatin coatings containing 2% (v/v EOs or submitted to the vapor of EOs (0.74 μL.cm-3. L. monocytogenes was quantified after one, 48 and 96 hours of storage (7 °C. In the in vitro tests, the EO of T. vulgaris presented higher activity. The two options used (edible gelatin coating and vapor activity, in spite of exercising effects with differentiated behaviors, presented antibacterial activity against L. monocytogenes inoculated in raw bovine meat (p < 0.05. Greatest antibacterial activity were obtained in the experiment that used edible coatings containing EOs, at 48 hours of storage reductions in bacterial counts between 1.09 and 1.25 Log CFU.g-1 were obtained. In the vapor effect experiment, the EO of T. vulgaris caused the highest reduction in the population of bacteria inoculated in raw bovine meat (p < 0.05, 0.40 Log CFU.g-1 at 96 hours of storage. This study supplied important information regarding new and promising natural alternatives, based on the concept of active packaging, for the control of L. monocytogenes in the meat industry.

Food intake is one of the main pathways of human exposure to chlorinated paraffins (CPs). This study assessed the dietary exposure for the general Chinese population to short-chain chlorinated paraffin (SCCPs) and medium-chain chlorinated paraffins (MCCPs) through meat and meat products. Twenty samples of meat and meat products from 20 Chinese provinces were collected in 2011. As the sampling sites covered about two-thirds of the Chinese population, the meat samples were considered to be representative of the true characteristics of CPs contamination in Chinese meat products. The concentrations of SCCPs and MCCPs in the meat samples were measured using the comprehensive two-dimensional gas chromatography electron capture negative ionization high-resolution time-of-flight mass spectrometry method. Forty-eight SCCP and MCCP homolog groups were detected in the meat samples. The mean SCCP and MCCP concentrations in all meat samples were 129 ± 4.1 ng g -1 wet weight and 5.7 ± 0.59 ng g -1 wet weight, respectively. The concentrations of SCCPs and MCCPs varied in samples from different provinces. The geographical distribution of CP concentrations was similar to the distribution of CPs manufacturing plants in China. The most abundant groups of SCCPs in all samples were C 10-11 Cl 6-7 , and the most abundant groups of MCCPs in most samples were C 14 Cl 7-8 . The possible sources of SCCPs and MCCPs in meat and meat products might be CP-42 and CP-52. The 50th percentile estimated daily intakes of SCCPs and MCCPs through meat consumption for a "standard" Chinese adult male were 0.13 and 0.0047 μg kg -1 bw d -1 , respectively, both much lower than the tolerable daily intakes (TDIs) for SCCPs and MCCPs. This preliminary risk assessment has indicated that the indirect exposure of SCCPs and MCCPs through meat consumption does not pose significant risk to human health in China.

Full Text Available The global meat market and primarily the chicken meat market represents a very dynamically developing area. The objective of the present article is the analysis of the chicken meat market in the world in order to identify the basic development trends associated with the development of production of and trade in chicken meat, and also in order to identify the individual entities controlling the global chicken meat market. In methodological terms, the article analyzes the development of production of, consumption of and trade (export and import in chicken meat in the years 1961–2009. The main sources of data necessary for the processing of the individual analyses are the FAOSTAT and UN COMTRADE databases. The results of the conducted analysis show the following findings. World production of poultry meat increased from 7.5 million tons to more than 86 million tons. The global market reacted in a flexible manner, in which there was an increase in volumes of executed trade from 271 thousand tons/year in the year 1961 to more than 10.7 million tons/year in the year 2010. Further, the value of world trade in chicken meat within the analyzed period increased from approximately USD 169 million to approximately USD 16 billion. If we analyze the global chicken meat market, it may be stated that it is very concentrated. The analysis of the global market further shows that Brazil, the USA and China represent, in terms of global production, consumption and trade, the main driving force on the chicken meat market. These three countries have a share in global production of approximately 46%, their share in global consumption ranges at a level of over 40%. The share of these countries in global export ranges at a level exceeding 50%.

Full Text Available Top-quality food produce and high profitability in processing requires high quality in raw materials. Therefore, to achieve these objectives, it is imperative to know the properties of the war materials, and the factors that influence these properties.The properties of the meat directly involved in increasing economic efficiency and final produce quality are the so-called technological properties: hydration capacity and water retention capacity of meat. These properties are determined by some factors belonging to the intrinsic quality of meat, animal slaughter methods, technological operations applied to the meat, and the auxiliary materials used.

Main Concerns of Pathogenic Microorganisms in Meat

Science.gov (United States)

Nørrung, Birgit; Andersen, Jens Kirk; Buncic, Sava

Although various foods can serve as sources of foodborne illness, meat and meat products are important sources of human infections with a variety of foodborne pathogens, i.e. Salmonella spp., Campylobacter jejuni/coli, Yersinia enterocolitica, Verotoxigenic E. coli and, to some extent, Listeria monocytogenes. All these may be harboured in the gastrointestinal tract of food-producing animals. The most frequent chain of events leading to meat-borne illness involves food animals, which are healthy carriers of the pathogens that are subsequently transferred to humans through production, handling and consumption of meat and meat products. Occurrences of Salmonella spp., C. jejuni/coli, Y. enterocolitica and Verotoxigenic E. coli in fresh red meat vary relatively widely, although most often are between 1 and 10%, depending on a range of factors including the organism, geographical factors, farming and/or meat production practices.

2016-01-01

Livestock is considered as one of the most important segments in agriculture since animal husbandry was practiced for centuries as a backyard system by rural families. Livestock plays as a powerful tool in rural development where meat industry contributes a dominant part. Meat and meat products become a vital component in the diet, which had been one of the main protein sources traditionally as well. The development in the livestock and meat industry of Sri Lanka basically depends upon religious, cultural, and economic factors. There is a growing demand for processed meat products in Sri Lankan urban culture and several large scale processors entered the business during the past few decades. The consumption of meat and meat products shows an upward trend in Sri Lanka during the last decade and is anticipated to increase further in future. The growth potential of the local meat industry is considerably high owing to the improvement of the market and consumer perception. The present status, trends, and future prospects for the Sri Lankan meat industry with respect to production, consumption, processing, marketing, and improvement are discussed in this review.

Kim, Jung Eun; Gordon, Susannah L; Ferruzzi, Mario G; Campbell, Wayne W

2015-01-01

Background: Dietary lipids are one of the most effective stimulators of carotenoid absorption, but very limited data exist on the impact of endogenous food sources of lipids to enhance carotenoid absorption. The co-consumption of whole egg with carotenoid-rich foods may increase overall carotenoid absorption via lipid-rich egg yolk. Objective: We designed this study to assess the effects of egg consumption on carotenoid absorption from a carotenoid-rich, raw mixed-vegetable salad. Design: Healthy young men (n = 16) consumed the same salad (all served with 3 g canola oil) with no egg (control), 75 g scrambled whole eggs (1.5 eggs) [low egg (LE)], and 150 g scrambled whole eggs (3 eggs) [high egg (HE)] (a randomized crossover design). Control, LE, and HE meals contained 23 mg, 23.4 mg (0.4 mg from eggs), and 23.8 mg (0.8 mg from eggs) total carotenoids and 3 g, 10.5 g (7.5 g from eggs), and 18 g (15 g from eggs) total lipids, respectively. Blood was collected hourly for 10 h, and the triacylglycerol-rich lipoprotein (TRL) fraction was isolated. Total and individual carotenoid contents, including lutein, zeaxanthin , α-carotene, β-carotene, and lycopene in TRL were analyzed, and composite areas under the curve (AUCs) were calculated. Results: The total mean (±SE) carotenoid AUC0–10h in TRL was higher for the HE meal than for LE and control meals [125.7 ± 19.4a compared with 44.8 ± 9.2b compared with 14.9 ± 5.2b nmol/L · 10 h, respectively (values without a common superscript letter differ); P eggs, including α-carotene, β-carotene, and lycopene, increased 3–8-fold (P eggs is an effective way to enhance carotenoid absorption from other carotenoid-rich foods such as a raw mixed-vegetable salad.

Full Text Available In the Republic of Croatia, game meat is consumed far less than meat of domestic animals. Yearly game meat consumption amounts to only 0.55 kg per household member. Consumers prefer meat of domestic animals, because it is cheaper, not paying attention to specific nutritive advantages of game meat. A research on the game meat market and consumers’ preferences was carried out on 101 examinees, chosen among inhabitants of Slavonia and Baranja. The majority of questioned inhabitants did consume game meat (92%, of whom 66% consider game meat to be of better quality than meat of domestic animals. Significant number of examinees considers game meat as healthy food, being also convinced that game was healthier to consume if hunted in their natural environment, than if reared on specialized farms (90%. Irrespective of quality, only 22% of examinees buy game meat, and 51% think such meat is too expensive. This is the main reason why consumers have game meat only once a month (51%. Taking into consideration monthly income of their respective household, 58% of examinees can afford game meat only once a month, and, if having an opportunity, they would opt for meat of roe deer (55% and rabbit (25%. When asked what would stimulate the game meat market in Croatia, 56% of examinees believe this could be achieved by lowering of prices, 27% think the issue could be addressed by opening of specialty stores, and only 17% opted for more aggressive marketing activities.

What does it take to increase the consumption of meat substitutes and attract new consumers? We identified main barriers and drivers by a consumer survey (n=553) in the U.K. and the Netherlands. Person-related factors (food neophobia and food choice motives) and product-related attitudes and beliefs towards meat and meat substitutes were compared between non-users (n=324), light/medium-users (n=133) and heavy-users of meat substitutes (n=96). Consumer acceptance was largely determined by the attitudes and beliefs towards meat substitutes and food neophobia. Key barriers for non-users and light/medium-users were the unfamiliarity with meat substitutes and the lower sensory attractiveness compared to meat. In addition, non-users had a higher tendency to avoid new foods. Hence, the less consumers were using meat substitutes, the more they wanted these products to be similar to meat. Although non-users and light/medium-users did recognize the ethical and weight-control aspects of meat substitutes, this was obviously less relevant to them. Actually, only heavy-users had high motivations to choose ethical foods, which explains their choice for meat substitutes. In order to make meat substitutes more attractive to meat consumers, we would not recommend to focus on communication of ethical arguments, but to significantly improve the sensory quality and resemblance to meat.

A notification from a laboratory concerning the detection of Campylobacter jejuni in a 6-year-old boy initiated the investigation carried out by the health authorities from Stendal district, in order to explain the morbidity rate caused by the germ. The day after the boy's pediatrician informed about a visit to a farm, which was confirmed by the head of the nursery. She told the health authorities about the consumption of raw milk during their visit at the farm.The following days more children fell sick. Within 10 days the total number of diseased children was 21. The health authorities asked for stool samples of the diseased children, nursery nurses and the head of the farm since raw milk presents a potential cause of infection. The health authorities together with the Saxony-Anhalt State Office for Consumer Protection conducted a retrospective cohort study. The aim was to explain the association between the exposure from raw milk consumption and the occurrence of the disease from C. jejuni. Based on a questionnaire data about the food and milk intake at the nursery and at home and about the trip to the farm were collected. 91% of the children's cohort and 86% of the adults' cohort were captured.The exposed group at risk showed a higher risk of falling ill than the group, which was not exposed. The risk factor raw milk explained the difference. Furthermore, the analysis of milk samples taken by the district veterinary office from 2 cows and from the farm's tank was able to detect the germs. The correlation of the illness, the consumption of raw milk, the detection of C. jejuni in the samples taken from the children and the samples taken from the cows was evident. Based on the case the health authorities recommended that heads of nurseries as well as heads of dairy farming in the district of Stendal needed to be advised on raw milk. Nurseries are still allowed to take trips to farms. However, raw animal derivates including milk must not be consumed. © Georg Thieme

Full Text Available While there are persistent rumors that the consumption of goat meat dishes increases blood pressure, there is no scientific evidence to support this. Two experiments were conducted to clarify whether or not blood pressure increases in conjunction with the consumption of goat meat dishes. In experiment 1, 24 Dahl/Iwai rats (15 weeks old, body weight 309.3±11.1 g were evenly separated into 4 groups. The control group (CP was fed a diet containing 20% chicken and 0.3% salt on a dry matter basis. The goat meat group (GM was fed a diet containing 20% goat meat and 0.3% salt. The goat meat/salt group (GS was fed a diet containing 20% goat meant and 3% to 4% salt. The Okinawan mugwort (Artemisia Princeps Pampan/salt group (GY was fed a diet containing 20% goat meat, 3% to 4% salt and 5% of freeze-dried mugwort powder. The experiment 1 ran for a period of 14 weeks during which time the blood pressure of the animals was recorded. The GS, and GY groups consumed significantly more water (p<0.01 than the CP and GM groups despite the fact that their diet consumption levels were similar. The body weight of animals in the CP, GM, and GS groups was similar while the animals in the GY group were significantly smaller (p<0.01. The blood pressure in the GM group was virtually the same as the CP group throughout the course of the experiment. In contrast, while the blood pressure of the animals in the GS and GY group from 15 to 19 weeks old was the same as the CP group, their blood pressures were significantly higher (p<0.01 after 20 weeks of age. The GY group tended to have lower blood pressure than the GS group. In experiment 2, in order to clarify whether or not the increase in blood pressure in the GS group and the GY group in experiment 1 was caused by an excessive intake of salt, the effects on blood pressure of a reduction of salt in diet were investigated. When amount of salt in the diet of the GS and GY group was reduced from 4% to 0.3%, the animal�

The most common sausages use only pork meat and are ripened for long periods. However, some countries with great tradition of sheep and goat meat consumption have the habit of eating some processed products of these meats. In Mediterranean countries as well as in other parts of the world, the meat from young lamb or kid is very usual and appreciated. These young milk fed animals producing lightweight carcasses are highly appreciated by consumers and are traditionally comm...

Update on the bird-egg syndrome and genuine poultry meat allergy.

Science.gov (United States)

Hemmer, Wolfgang; Klug, Christoph; Swoboda, Ines

Allergy to poultry meat is rare and affects both children and adults. The prevalence of poultry meat allergy is unknown, but presumably is similar to that of red meat allergy. There is no close relationship between allergy to poultry meat and allergy to red meat. Poultry meat allergy may present as primary (genuine) food allergy or as secondary food allergy resulting from cross-reactivity. Secondary poultry meat allergy may arise in the context of bird-egg-syndrome, which is due to sensitization to serum albumins present in many tissues including muscle tissue and egg yolk (Gal d 5). Primary sensitization to serum albumin may happen via the respiratory tract through exposure to pet birds (mainly in adults) or within the context of egg allergy in early childhood. Due to the heat lability of serum albumins, reactions are often limited to the skin upon contact with raw meat. Symptoms from meat ingestion are rare and mostly mild, whereas systemic reactions are common after ingestion of raw or soft-boiled egg yolk. Primary poultry meat allergy is mainly seen in adolescents and young adults, though hypersensitivity may have started already at (pre)school age. Egg allergy is usually absent. Typical symptoms of primary poultry meat allergy include OAS (±dyspnea), gastrointestinal complaints, urticaria and angioedema. Severe anaphylaxis with cardiovascular symptoms is rare. Chicken and turkey meat are highly cross-reactive and responsible for most reactions, while duck and goose meat causes milder or no symptoms. Soups, sausages, and ham represent relevant allergen sources, too. Patients with poultry meat allergy unexpectedly often suffer from concomitant allergy to fish and possibly shrimp. Serum specific IgE against fish and shrimp is found in respectively 60 and 40 % of sera, suggestive of cross-reactive allergens in these foods. The allergens thus far recognized in genuine poultry meat are LMW proteins of 5-25 kDa. One of them has been identified as �
