A diagnostic instrument comprising a combined assessment of core control and assurance activities and a microbial assessment instrument were used to measure the performance of current food safety management systems (FSMSs) of two poultry meat preparation companies. The high risk status of the company's contextual factors, i.e., starting from raw materials (poultry carcasses) with possible high numbers and prevalence of pathogens such as Campylobacter spp., requires advanced core control and assurance activities in the FSMS to guarantee food safety. The level of the core FSMS activities differed between the companies, and this difference was reflected in overall microbial quality (mesophilic aerobic count), presence of hygiene indicators (Enterobacteriaceae, Staphylococcus aureus, and Escherichia coli), and contamination with pathogens such as Salmonella, Listeria monocytogenes, and Campylobacter spp. The food safety output expressed as a microbial safety profile was related to the variability in the prevalence and contamination levels of Campylobacter spp. in poultry meat preparations found in a Belgian nationwide study. Although a poultry meat processing company could have an advanced FSMS in place and a good microbial profile (i.e., lower prevalence of pathogens, lower microbial numbers, and less variability in microbial contamination), these positive factors might not guarantee pathogen-free products. Contamination could be attributed to the inability to apply effective interventions to reduce or eliminate pathogens in the production chain of (raw) poultry meat preparations.

Muscle growth and poultry meat quality issues.

Science.gov (United States)

Petracci, Massimiliano; Cavani, Claudio

2012-01-01

Over the past 50 years the worldwide growing demand of poultry meat has resulted in pressure on breeders, nutritionists and growers to increase the growth rate of birds, feed efficiency, size of breast muscle and reduction in abdominal fatness. Moreover, the shift toward further processed products has emphasized the necessity for higher standards in poultry meat to improve sensory characteristics and functional properties. It is believed that genetic progress has put more stress on the growing bird and it has resulted in histological and biochemical modifications of the muscle tissue by impairing some meat quality traits. The most current poultry meat quality concerns are associated with deep pectoral muscle disease and white striping which impair product appearance, and increased occurrence of problems related with the meat's poor ability to hold water during processing and storage (PSE-like condition) as well as poor toughness and cohesiveness related to immaturity of intramuscular connective tissue. This paper is aimed at making a general statement of recent studies focusing on the relationship between muscle growth and meat quality issues in poultry.

Summary 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 se...

2015-06-01

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.

Influence of color on dielectric properties of marinated poultry breast meat.

Science.gov (United States)

Samuel, D; Trabelsi, S

2012-08-01

The dielectric behavior of foods when exposed to radio-frequency and microwave electric fields is highly influenced by moisture content and the degree of water binding with constituents of the food materials. The ability to correlate specific food quality characteristics with the dielectric properties can lead to the development of rapid, nondestructive techniques for such quality measurements. Water-holding capacity is a critical attribute in meat quality. Up to 50% of raw poultry meat in the United States is marinated with mixtures of water, salts, and phosphates. The objective of this study was to determine if variations in breast meat color would affect the dielectric properties of marinated poultry meat over a broad frequency range from 500 MHz to 50 GHz. Poultry meat was obtained from a local commercial plant in Georgia (USA). Color and pH measurements were taken on the breast filets. Groups of breast filets were sorted into classes of pale and normal before adding marination pickup percentages of 0, 5, 10, and 15. Breast filets were vacuum-tumbled and weighed for pickup percentages. Dielectric properties of the filets were measured with a coaxial open-ended probe on samples equilibrated to 25°C. Samples from pale meat exhibited higher dielectric properties than samples from normal meat. No differences could be observed between samples from pale and normal meat after marination of the samples. Overall, dielectric properties increased as the marination pickup increased (α=0.05). Marination pickup strongly influenced the dielectric loss factor. Differences between samples marinated at different pickup levels were more pronounced at lower frequencies for the dielectric loss factor. As frequency increased, the differences between samples decreased. Differences in dielectric constant between samples were not as consistent as those seen with the dielectric loss factor.

1993-01-01

Ionising radiation in doses used for radurisation (Recommendations of international organizations admit for poultry meat doses up to 5 kGy. Practically doses up to 3 kGy are applied does not influence erythromycin concentration in poultry meat. Doses on a level 10 kGy reduce its concentration in slurry more effectively, but results of earlier studies on penicillin and streptomycin suggest, that reduction of erythromycin level in meat should be smaller than in slurry. This allows an assumption that poultry meat irradiation with radurisation doses (up to 5 kGy), does not cause danger of overlooking of erythromycin residues in meat, with traditional, microbiological methods of detection.

1994-12-31

The purpose of the study was an evaluation of the effect of ionizing radiation on detection of oxytetracycline residues in poultry meat. Oxytetracycline was chosen as a representative of tetracyclines which are often applied in poultry for therapeutical reasons. The experiment was conducted using both broiler meat treated by oxytetracycline and slurry of broiler meat containing appropriate concentration of this antibiotic. A traditional microbiological method for determination of antibiotics antimicrobial activity was used. A significant decrease of oxytetracycline concentration in meat slurry as a result of irradiation was noted. A dose of 1 kGy reduced concentration of tetracycline to ca 40% and a dose of 3 kGy reduced it to ca 3%. In ground poultry meat a dose of 1 kGy reduced this antibiotic concentration to 70%, a dose of 3 kGy reduced oxytetracycline concentration to 35% and a 5 kGy dose reduced it up to ca 18% of initial concentration. It can be concluded that irradiation of poultry meat with radurization doses can cause some difficulties in detection of tetracycline residues in meat using traditional microbiological methods of detection.

Full Text Available The paper goal was to study consumer behaviour for poultry meat. In this purpose 100 individuals participated to a questionnaire based survey  in a supermarket of  Bucharest. Specific methods of marketing research in such a case assured the statistical processing of the respondents’ answers. The results pointed out an increased consumption of poultry meat,  a preference for fresh chicken meat which is daily bought  or 2-3 times a week in a varied amount ranging between 1-1.5 kg depending on consumer’s income for covering the family need. The main factors influencing consumer buying decision are the sensorial meat characteristics, meat quality, origin, price, prepaking grade. As a conclusion producers have to pay more attention to these aspects in their future strategy for producing and commercialising poultry meat.

In 2007 and 2008, a monitoring study was carried out in Poland to examine the occurrence of thermotolerant Campylobacter spp. in raw and cooked chicken products available on the retail market. A total of 912 samples were tested: 443 samples of raw chicken meat, 146 samples of giblets, and 323 ready-to-eat poultry products (150 samples of spit-roasted chicken, 56 samples of smoked chicken, and 117 samples of pâté and cold meats). A high level of contamination of raw chicken meat (51.7% of samples) and chicken giblets (47.3% of samples) was detected. However, thermotolerant Campylobacter spp. were found in only 1.2% of the ready-to-eat poultry products.

Microbiological quality of poultry meat: a review

Directory of Open Access Journals (Sweden)

GC Mead

Full Text Available Poultry meat can be contaminated with a variety of microorganisms, including those capable of spoiling the product during chill storage, and certain foodborne pathogens. Human illness may follow from handling of raw meat, undercooking or mishandling of the cooked product. While Salmonella and Campylobacter spp. remain the organisms of greatest global concern in this respect, others present include the more recently reported Arcobacter and Helicobacter spp. and, occasionally, verotoxigenic Escherichia coli. Also considered here is the growing problem of antimicrobial resistance among poultry-associated pathogens. Because of the need for a systematic and universally applicable approach to food safety control, the Hazard Analysis Critical Control Point (HACCP concept is increasingly being introduced into the Poultry Industry, and Quantitative Risk Assessment (QRA is being applied to microbial hazards. Among a number of completed and on-going studies on QRA are those undertaken by FAO/WHO on Salmonella and Campylobacter in broilers. In the case of Campylobacter, however, any QRA must assume at present that all strains have the same pathogenic potential for humans and comparable survival capabilities, even though this is unlikely to be the case. Implementation of the HACCP system in poultry processing plants addresses zoonotic agents that are not detectable by conventional meat inspection procedures and can help to control contamination of carcasses with spoilage organisms. The system brings obvious benefits in optimising plant hygiene, ensuring compliance with legislation and providing evidence of 'due diligence' on the part of the processor. It is now being applied globally in two different situations: in one, such as that occurring in the USA, carcass contamination is clearly reduced as carcasses pass through the process and are finally chilled in super-chlorinated water. There is also the option to use a chemical-rinse treatment for further

Formation of Poultry Meat Flavor by Heating Process and Lipid Oxidation

Directory of Open Access Journals (Sweden)

Full Text Available Flavor is an important factor in the acceptance of food. Flavor of poultry meat is naturally formed through a specific process of heating, where various chemical reactions complex occurred among nonvolatile precursors in fatty tissue or in lean tissue. The main flavor in the form of volatile and nonvolatile components play a major influence on the acceptance of various processed meat, especially the taste. Removal of sulfur components decreases meat flavor (meaty, while removal of carbonyl compounds decrease the specific flavor and increases common flavor of the meat. Poultry meat has a fairly high fat content that easily generates lipid oxidation. Lipid oxidation in poultry meat is a sign that the meat was damaged and caused off odor. Addition of antioxidants in the diet can inhibit lipid oxidation in the meat. Lipids interaction with proteins and carbohydrates is unavoidable during the thermal processing of food, causing the appearance of volatile components. The main reaction in meat flavor formation mechanism is Maillard reaction followed by Stecker reaction and degradation of lipids and thiamine. They involve in the reaction between carbonyl and amine components to form flavor compounds, which enhance the flavor of poultry meat.

Campylobacter, a common poultry intestine commensal, is a well known cause of human gastric illnesses across the globe. Consumption of contaminated poultry meat is a major cause of Campylobacter related infections. In the present study, radiation sensitivity of indigenous strains of C. jejuni and C. coli isolated from poultry was evaluated. The decimal reduction dose (D 10 ) values of different Campylobacter isolates at 0-4 o C in saline and blood broth were in the range of 0.120-0.210 kGy and 0.170-0.234 kGy, respectively. D 10 values in chicken meat homogenate for Campylobacter were in the range of 0.110-0.190 kGy. Chicken meat samples were inoculated with C. jejuni and exposed to gamma radiation to study the effectiveness of radiation treatment in elimination of Campylobacter. Radiation treatment with a dose of 1 kGy could achieve complete elimination of 10 5 CFU of Campylobacter/g in poultry meat samples. No recovery of Campylobacter was observed, even after enrichment and selective plating in 1 kGy treated chicken meat samples stored at 4 o C up to 7 days. Present study shows that irradiation of poultry meat with 1 kGy can ensure safety of poultry meat. - Highlights: → Campylobacter isolates were sensitive to gamma radiation. → Low dose of 1 kGy is effective for 5-log reduction of Campylobacter in chicken meat. → No recovery of Campylobacter in radiation processed samples during storage. → First report on radiation sensitivity of Indian Campylobacter isolates.

Listeria is the genus of a bacteria found in soil and water and some animals, including poultry and cattle. It can be present in raw milk and food made from raw milk. It can also live in food processing plants and contaminate a variety of processed meats. Microscopically, Listeria species appear as small, Gram-positive rods, which are sometimes arranged in short chains. In direct smears, they can be coccoid, so they can be mistaken for streptococci. Longer cells can resemble corynebacteria. Flagella are produced at room temperature but not at 37°C. Haemolytic activity on blood agar has been used as a marker to distinguish Listeria monocytogenes among other Listeria species, but it is not an absolutely definitive criterion. Further biochemical characterization is necessary to distinguish between the different Listeria species. The objective of this study was to detect, isolate and identify Listeria monocytogenes from poultry meat. Within a period of six months from January to June 2017, a total of 15 samples were collected. Three samples were positive for the presence of Listeria monocytogenes. Biochemical and microbiological tests as well as PCR technique using specific primers were used to confirm L. Monocytogenes in the samples.

Full Text Available Poultry meat production has doubled in past 40 years in the world, with the tendency of constant growth, and its production volume exceeds beef, but is behind pork production. For poultry meat production it is typical that its annual increase exceeds pork as well as beef production. The biggest producers of poultry meat are Asia, North and South America and Europe. The most significant category of poultry is meat of young chicken (broilers. Cobb, Ross and Hubbard broiler provenance are most common in Serbia. The objective of this investigation was to analyse poultry meat production volume in Serbia, observed during three six-years periods - A (1984-1989, B (1994-1999 i C (2004-2009. For data processing there were used the data obtained from Statistical Yearbooks of Serbia from 1984. to 2009. It was found out that average poultry meat production in period A was 108,33 ± 7,00 thousand tonnes, than it statistically significantly decreased and in period B it was 76,67±5,54 thousand tonnes, and finally in period C it was 72,17± 5,78 thousand tonnes.

A number of beneficial effects can be achieved by irradiating meats and poultry under different conditions. It is possible, for example, to extend the market life of both fresh and processed meats by applying radiation doses sufficient to reduce the microbial population, thereby delaying onset of spoilage; higher doses aimed at destroying both spoilage and pathogenic microorganisms can also be applied to meats, packaged to prevent recontamination, resulting in a shelf-stable product; the objective may also be to inactivate pathogenic bacteria, parasites and viruses in order to obtain a product which is acceptable from the point of view of public health.

Utilization of byproducts and waste materials from meat, poultry and fish processing industries: a review.

Science.gov (United States)

Jayathilakan, K; Sultana, Khudsia; Radhakrishna, K; Bawa, A S

2012-06-01

India is bestowed with vast livestock wealth and it is growing at the rate of 6% per annum. The contribution of livestock industry including poultry and fish is increasing substantially in GDP of country which accounts for >40% of total agricultural sector and >12% of GDP. This contribution would have been much greater had the animal by-products been also efficiently utilized. Efficient utilization of by-products has direct impact on the economy and environmental pollution of the country. Non-utilization or under utilization of by-products not only lead to loss of potential revenues but also lead to the added and increasing cost of disposal of these products. Non-utilization of animal by-products in a proper way may create major aesthetic and catastrophic health problems. Besides pollution and hazard aspects, in many cases meat, poultry and fish processing wastes have a potential for recycling raw materials or for conversion into useful products of higher value. Traditions, culture and religion are often important when a meat by-product is being utilized for food. Regulatory requirements are also important because many countries restrict the use of meat by-products for reasons of food safety and quality. By-products such as blood, liver, lung, kidney, brains, spleen and tripe has good nutritive value. Medicinal and pharmaceutical uses of by-product are also highlighted in this review. Waste products from the poultry processing and egg production industries must be efficiently dealt with as the growth of these industries depends largely on waste management. Treated fish waste has found many applications among with which the most important are animal feed, biodiesel/biogas, dietectic products (chitosan), natural pigments (after extraction) and cosmetics (collagen). Available information pertaining to the utilization of by-products and waste materials from meat, poultry and fish and their processing industries has been reviewed here.

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.

Considerable work on consumers' food safety habits has highlighted issues associated with home food preparation. However, consumer handling of foods, such as poultry, during shopping and storage has not been noted. The objective of this study was to determine consumer behaviors during purchasing and initial storage of raw poultry to determine potential cross-contamination issues. A shop-along observational study was conducted to determine actual shopping, transportation, and storage behavior of consumers who purchase raw poultry products. Neither hand sanitizer nor wipes were observed in 71% of grocery store meat sections of stores visited. Plastic bags could be found in the meat section 85% of the time, but only 25% of shoppers used the bag for their raw poultry purchases. During checkout, the poultry was bagged separately from other products 71% of the time. A majority of shoppers stored raw poultry in the original package without an additional container or overwrap. Overall, there needs to be an increase in food safety education on the handling of poultry during purchasing, transportation, and storage.

This research was aimed at the evaluation of the antimicrobial activity exerted by poultry protein hydrolyzates derived from industrial leftovers added to minced turkey meat, intended for the production of burgers for human consumption. Hydrolyzates were obtained through enzymatic hydrolysis from poultry bone and meat trimmings, as by-products from the poultry industry. Colony forming unit assays, under both laboratory and industrial conditions, were performed to assess microbial growth. Poultry protein hydrolyzates inhibited microbial growth occurring in semi-finished turkey meat during the normal retention period because of their water holding capacity resulting in a decreased water activity. Overall, the findings demonstrated that poultry protein hydrolyzates could decrease mesophilic, psychrophilic, and thermophilic bacterial growth for the entire product shelf-life. Bacterial growth inhibition obtained in minced turkey meat by addition of poultry protein hydrolyzates (1.5%), hygroscopic amino acids mixture (1.5%) or sodium chloride (1%) was similar. It is suggested that the use of hydrolyzates could allow the reduction of salt content in poultry meat based products leading to the production of low-sodium turkey food still maintaining acceptable sensory characteristics.

Beneficial Effects of Poultry Meat Consumption on Cardiovascular Health and the Prevention of Childhood Obesity

Directory of Open Access Journals (Sweden)

Mustafa Metin Donma

2017-08-01

Full Text Available Poultry meat is an animal product important in human nutrition. A variable, and moderate energy content, highly digestible proteins of good nutritional quality, unsaturated lipids, fat-soluble and B-complex vitamins as well as minerals make poultry meat a valuable food. Poultry meat is one of the recommended constituents of Dietary Approaches to Stop Hypertension Diet as well as the Mediterranean Diet. The substitution of red meat with poultry as well as fish, nuts and legumes decreases the risk of developing type 2 and gestational diabetes mellitus, improves glycemic control and cardiovascular risk factors. Low-fat diets supported by fruits, grains, nuts, fish and poultry instead of red meat yields cardiovascular health benefits. Anti-inflammatory and antioxidative diet enriched with high-quality foods reduces pro-inflammatory cytokines. This favors anti-inflammatory milieu which in turn improves insulin sensitivity and endothelial function and ultimately act as a barrier to obesity, metabolic syndrome, type 2 diabetes mellitus and development of atherosclerosis. The nutritive value of poultry meat depends on different factors such as age, feeding, keeping, hybrids, carcass parts and type of meat. Preventive measures against risky aspects of the matter should be developed. Since the use of antibiotics leads to the development of antibiotic resistant pathogens, antibiotics must be replaced by herbs and spices with growth promoting effects, antimicrobial properties, and other health related benefits to solve the problem. Enrichment and fortification with nutrients may cause poultry meat to gain even more functional food character.

Skarp, C P A; Hänninen, M-L; Rautelin, H I K

2016-02-01

The incidence of human infections caused by Campylobacter jejuni and Campylobacter coli, the main bacterial agents of gastrointestinal disease, has been increasing worldwide. Here, we review the role of poultry as a source and reservoir for Campylobacter. Contamination and subsequent colonization of broiler flocks at the farm level often lead to transmission of Campylobacter along the poultry production chain and contamination of poultry meat at retail. Yet Campylobacter prevalence in poultry, as well as the contamination level of poultry products, vary greatly between different countries so there are differences in the intervention strategies that need to be applied. Temporal patterns in poultry do not always coincide with those found in human infections. Studies in rural and urban areas have revealed differences in Campylobacter infections attributed to poultry, as poultry seems to be the predominant reservoir in urban, but not necessarily in rural, settings. Furthermore, foreign travel is considered a major risk factor in acquiring the disease, especially for individuals living in the northern European countries. Intervention strategies aimed at reducing Campylobacter colonization in poultry and focused at the farm level have been successful in reducing the number of Campylobacter cases in several countries. Increasing farm biosecurity and education of consumers are likely to limit the risk of infection. Overall, poultry is an important reservoir and source of human campylobacteriosis, although the contribution of other sources, reservoirs and transmission warrants more research.

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.

2018-05-01

Full Text Available The objective of this study was to investigate and summarize the levels of incidence of Salmonella spp., Listeria monocytogenes, Staphylococcus aureus and Campylobacter spp. in poultry meat commercialized in Europe. After systematic review, incidence data and study characteristics were extracted from 78 studies conducted in 21 European countries. Pooled prevalence values from 203 extracted observations were estimated from random-effects meta-analysis models adjusted by pathogen, poultry type, sampling stage, cold preservation type, meat cutting type and packaging status. The results suggest that S. aureus is the main pathogen detected in poultry meat (38.5%; 95% CI: 25.4–53.4, followed by Campylobacter spp. (33.3%; 95% CI: 22.3–46.4%, while L. monocytogenes and Salmonella spp. present lower prevalence (19.3%; 95% CI: 14.4–25.3% and 7.10%; 95% CI: 4.60–10.8%, respectively. Despite the differences in prevalence, all pathogens were found in chicken and other poultry meats, at both end-processing step and retail level, in packed and unpacked products and in several meat cutting types. Prevalence data on cold preservation products also revealed that chilling and freezing can reduce the proliferation of pathogens but might not be able to inactivate them. The results of this meta-analysis highlight that further risk management strategies are needed to reduce pathogen incidence in poultry meat throughout the entire food chain across Europe, in particular for S. aureus and Campylobacter spp.

PRODUCTION OF POULTRY MEAT AND EGGS IN THE REPUBLIC OF CROATIA AND IN THE EUROPEAN UNION

Directory of Open Access Journals (Sweden)

Davor Bošnjaković

2017-01-01

Full Text Available Poultry meat and eggs are a significant source of nutrients in the human diet. Poultry products are widely consumed because they are nutritionally valuable, there are no religious restrictions on consumption, it is relatively easy to prepare diverse meals based on poultry, and the price of such products is relatively low. The aim of this research was to investigate the development of poultry production in the Republic of Croatia in the period 2010-2014, comprising the period of two years after Croatia joined the EU. The paper also compares data of poultry production in Croatia and in the EU. Over the period in question, total meat production in Croatia was reduced by 23%, meat import was increased by 45%, poultry meat export was increased by 46%, and production of eggs decreased by 20%. At the same time, in the EU countries poultry production was increased by 8.8% on average, export was increased by 10%, and import was reduced by 3.7%, while the egg production stagnated. In 2014, consumption of poultry meat in Croatia was 18.3 kg per capita, and in the EU 26.8 kg per capita. Self-sufficiency in the poultry production over the analyzed period was not satisfactory, therefore in the coming years, Croatia will have to develop quickly this important branch of livestock breeding. In addition to conventional production, faster development refers to production of organic and functional poultry products.

Science.gov (United States)

Mudalal, S; Lorenzi, M; Soglia, F; Cavani, C; Petracci, M

2015-04-01

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.

An Immunoassay for Quantification of Contamination by Raw Meat Juice on Food Contact Surfaces.

Science.gov (United States)

Chen, Fur-Chi; Godwin, Sandria; Chambers, Edgar

2016-11-01

Raw chicken products often are contaminated with Salmonella and Campylobacter , which can be transmitted from packages to contact surfaces. Raw meat juices from these packages also provide potential media for cross-contamination. There are limited quantitative data on the levels of consumer exposure to raw meat juice during shopping for and handling of chicken products. An exposure assessment is needed to quantify the levels of transmission and to assess the risk. An enzyme-linked immunosorbent assay (ELISA) was developed and validated for quantitative detection of raw meat juice on hands and various food contact surfaces. Analytical procedures were designed to maximize the recovery of raw meat juice from various surfaces: hands, plastic, wood, stainless steel, laminated countertops, glass, and ceramics. The ELISA was based on the detection of a soluble muscle protein, troponin I (TnI), in the raw meat juice. The assay can detect levels as low as 1.25 ng of TnI, which is equivalent to less than 1 μl of the raw meat juice. The concentrations of TnI in the raw meat juices from 10 retail chicken packages, as determined by ELISA, were between 0.46 and 3.56 ng/μl, with an average of 1.69 ng/μl. The analytical procedures, which include swabbing, extraction, and concentration, enable the detection of TnI from various surfaces. The recoveries of raw meat juice from surfaces of hands were 92%, and recoveries from other tested surfaces were from 55% on plastic cutting boards to 75% on laminated countertops. The ELISA developed has been used for monitoring the transfer of raw meat juice during shopping for and handling of raw chicken products in our studies. The assay also can be applied to other raw meat products, such as pork and beef.

Microbiological safety of tenderized, proteinaceous, semi-processed and processed food prepared from poultry treated with ionizing radiation and other processes

International Nuclear Information System (INIS)

Klinger, I.; Lapidot, M.

1998-01-01

From a microbiological point of view, poultry meat is considered to be one of the most contaminated raw foods, harbouring bacteria, including pathogens such as Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Campylobacter spp. Some of these pathogens can survive the heat treatment used during the further processing of poultry meat into ready to eat products such as sausages and patties, and thus endanger consumer health, particularly in the young, the elderly and the immunocompromised. L. monocytogenes is of particular concern. This Gram positive, non-spore forming, psychrotrophic pathogen has been recognized as one of the causes of a severe food borne illness. The organism is relatively heat stable and can multiply under refrigeration conditions, but is sensitive to ionizing radiation. A survey conducted in Israel demonstrated that raw poultry meat was heavily contaminated with L. monocytogenes and that the pathogen could also be recovered from ready to eat poultry products. It was proposed that treatment of the raw meat with ionizing radiation prior to heating and use of the hazard analysis critical control point concept in the further processing plant would result in the elimination of contamination in ready to eat products.

2016-09-01

Full Text Available The Total Antibiotics test is a microbial inhibition test which has been recently introduced for the detection of antibiotics in meat. The aim of this study was to determine whether it would be suitable for the detection of coccidiostats in poultry meat. A comparison with the Premi®Test was assessed also for the suitability of the detection of coccidiostats in poultry meat. A selection of poultry meat samples of different organ parts were assessed with 14 samples from Slovakian farms that had previously been tested for coccidiostats by the Veterinary and Food Institute in Košice. In addition, another 8 samples from varied Slovakian supermarkets such as Lidl, Billa and Tesco with samples of chicken or duck meat, were tested. Each prepared sample was added to the Total Antibiotics kit tubes and incubated. The samples from all sources showed a mixture of positive and negative results for the detection of coccidiostats.

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.

The relationship between the consumption of meat and health is multifaceted, and it needs to be analyzed in detail, with specific attention to the relevant differences that characterize the effects of the different meat types, as yet considered by only a limited literature. A variable but moderate energy content, highly digestible proteins (with low levels of collagen) of good nutritional quality, unsaturated lipids (mainly found in the skin and easily removed), B-group vitamins (mainly thiamin, vitamin B6, and pantothenic acid), and minerals (like iron, zinc, and copper) make poultry meat a valuable food. Epidemiological studies performed across the world, in highly diverse populations with different food preferences and nutritional habits, provide solid information on the association between poultry consumption, within a balanced diet, and good health. Consumption of poultry meat, as part of a vegetable-rich diet, is associated with a risk reduction of developing overweight and obesity, cardiovascular diseases, and type 2 diabetes mellitus. Also, white meat (and poultry in particular) is considered moderately protective or neutral on cancer risk. The relevance of poultry meat for humans also has been recognized by the UN Food and Agricultural Organization (FAO), who considers this widely available, relatively inexpensive food to be particularly useful in developing countries, where it can help to meet shortfalls in essential nutrients. Moreover, poultry meat consumption also contributes to the overall quality of the diet in specific ages and conditions (prior to conception, during pregnancy up to the end of breastfeeding, during growth, and in the geriatric age) and is suitable for those who have an increased need for calorie and protein compared to the general population.

The major objective of this study was to investigate the prevalence of Shiga toxin (Stx)-producing Escherichia coli (STEC) in different types of food samples and to compare their genetic relatedness with STEC strains previously isolated from animal sources in Bangladesh. We investigated a total of 213 food samples, including 90 raw meat samples collected from retail butcher shops, 20 raw milk samples from domestic cattle, and 103 fresh juice samples from street vendors in Dhaka city. We found that more than 68% (n = 62) of the raw meat samples were positive for the stx gene(s); 34% (n = 21) of buffalo meats and 66% (n = 41) of beef. Approximately 10% (n = 2) of the raw milk and 8% (n = 8) of the fresh juice samples were positive for stx. We isolated STEC O157 from seven meat samples (7.8%), of which two were from buffalo meats and five from beef; and no other STEC serotypes could be isolated. We could not isolate STEC from any of the stx-positive raw milk and juice samples. The STEC O157 isolates from raw meats were positive for the stx(2), eae, katP, etpD, and enterohemorrhagic E. coli hly virulence genes, and they belonged to three different phage types: 8 (14.3%), 31 (42.8%), and 32 (42.8%). Pulsed-field gel electrophoresis (PFGE) typing revealed six distinct patterns among seven isolates of STEC O157, suggesting a heterogeneous clonal diversity. Of the six PFGE patterns, one was identical and the other two were ≥90% related to PFGE patterns of STEC O157 strains previously isolated from animal feces, indicating that raw meats are readily contaminated with fecal materials. This study represents the first survey of STEC in the food chain in Bangladesh.

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.

The radiation resistance and ability of Listeria monocytogenes ATCC 7644, 15313, 43256, and 49594 to multiply on irradiated, air-packed, refrigerated raw or cooked turkey breast meat nuggets (ca. 25 g) and ground turkey breast meat was investigated. Gamma-radiation D values for L. monocytogenes were significantly different on raw and cooked nuggets, 0.56 +/- 0.03 kGy and 0.69 +/- 0.03 kGy, respectively; but they were not significantly different (P less than or equal to 0.05) on raw and cooked ground turkey meat. High populations (approximately 10(9) CFU/g) of L. monocytogenes declined during 14 days of storage at 4 degrees C in both irradiated and nonirradiated samples of raw but not of cooked ground turkey breast meat. A moderate inoculum (approximately 10(3) CFU/g) did not survive a radiation dose of 3 kGy. The population increased in cooked but not in raw samples of irradiated ground turkey meat stored at either 2 or 7 degrees C for 21 days. The D value changed significantly from 0.70 +/- 0.04 to 0.60 +/- 0.02 kGy when the product was cooked to an internal temperature of 80 degrees C before irradiation. Growth on either raw or cooked turkey meat did not alter the radiation resistance of L. monocytogenes. Analyses were performed for pH, a(w), moisture, and reducing potential of raw and cooked turkey meat and for pH, amino acid profile, thiamine, and riboflavin contents of aqueous extracts of raw and cooked turkey meats without identifying the factor or factors involved in differences in the survival and multiplication of L. monocytogenes on raw and cooked meat

Full Text Available The present research was conducted to provide information on the influence of stunning methods in conjunction with refrigeration and freezing time on the textural and rheological properties of raw meat. Pork raw meat, commercially available, was analyzed for textural properties such as hardness, cohesiveness, adhesiveness and fracture force. Sample were analyzed fresh, after 3 days of refrigeration, and 15 days, 30days and 60 days freezing time in commercially available refrigerators mimicking the storing conditions used by consumers. For pork raw meat, hardness increased sharply after 3 days of refrigeration and showed no significant differences after 15days of freezing compared to 3days refrigeration time. After 30 days of freezing the raw pork meat samples’ hardness decreased significantly compared to the hardness of the samples freeze for15 days. Hardness of gas stunning raw pork meat samples compared to electrical stunning raw pork meat samples was 2.57 times higher indicating a better firmness of the gas stunning raw pork meat. The cohesiveness of the raw pork meat from gas stunned animals maintained its levels after 60 days of freezing while the meat from electrically stunned animals showed significant modificatio

The aim of this study was to determine the physical and microbiological quality of chicken meat produced by the different type of enterprise slaughterhouse in Karanganyar District. The number of 20 poultry slaughterhouses was determined by convenience sampling method. The samples of chicken meat were randomly collected from medium enterprise poultry slaughterhouses (n=12) and small enterprise poultry slaughterhouses (n=8). A survey was carried out among poultry slaughterhouses in Karanganyar District. All the samples were subjected to physical quality consisted of pH test, texture, and color, while microbiological quality consisted of total plate count, microbial detection of Escherichia coli and Salmonella. The data were analyzed using descriptive quantitative analysis. The study showed that chicken meat in 6 small enterprise slaughterhouses and 11 medium enterprise slaughterhouses had normal pH of 5.81 - 6.3. Color and texture of chicken meats had relatively normal in both small and medium enterprise slaughterhouses. The total plate count of chicken meat showed in both small and medium enterprise slaughterhouses was 1x101 CFU/gr, and Salmonella was detected in 1 medium enterprise slaughterhouse. The overall results of the study suggest that the potential risk of chicken meat contamination depends on the processing of chicken meat in poultry slaughterhouses.

Microbiologic studies were carried out in the production of poultry meat in a poultry dressing combine of the Stork system. Examined were a total of 125 washing samples taken at the 9th, 11th and 15th hour from the scalding vat, the cooling vat, the machine of eviscerating and the skin surface after plucking, eviscerating and shower washing and prior to packing the carcasses. It was found that the count of aerobic organisms continuously rose during the technologic processing of the slaughtered birds with regard to the surface of the carcasses, the peak values of the total counts and that of coliforms being reached during evisceration. It was further established that shower washing of the carcasses immediately following evisceration guaranteed a washing effect so far as the microflora on the surface was concerned, amounting to 77.60 per cent. So far as the coliform bacteria was concerned this effect was found to be equal to 89.78 per cent. The total count of aerobic microflora on the surface of carcasses prior to packing was found to vary within the range of 3000 to 72000, while the count of coliforms ranged from 100 to 1800/cm2.

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.

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

A total of 120 broiler wing meat samples (60 packaged pieces wrapped using strech film in styrofoam plates and 60 unpackaged pieces bought from different markets in Hatay province were analysed. Listeria spp. was isolated from 57 (47.5% out of 120 samples. Fifty-four, out of 57 Listeria spp. isolates were identified as L. monocytogenes. L. monocytogenes was isolated from the samples collected during the spring, winter, summer, and autumn at the levels of 26.6%, 40%, 53.3%, 60%, respectively. In this study, the isolation rates were found to be the highest in autumn, while the isolation rates were found to be the lowest in spring. As a consequence, high prevalence of Listeria spp. and L. monocytogenes in poultry wing meat samples may pose a risk for human health. We consider that with obeying the rules of good hygiene practices (GHP, good manufacturing practices (GMP and HACCP can minimize the contamination with Listeria spp.

2012-01-01

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.

White striping and woody breast myopathies in the modern poultry industry: a review.

Science.gov (United States)

Kuttappan, V A; Hargis, B M; Owens, C M

2016-11-01

Myopathies are gaining the attention of poultry meat producers globally. White Striping (WS) is a condition characterized by the occurrence of white striations parallel to muscle fibers on breast, thigh, and tender muscles of broilers, while Woody Breast (WB) imparts tougher consistency to raw breast fillets. Histologically, both conditions have been characterized with myodegeneration and necrosis, fibrosis, lipidosis, and regenerative changes. The occurrence of these modern myopathies has been associated with increased growth rate in birds. The severity of the myopathies can adversely affect consumer acceptance of raw cut up parts and/or quality of further processed poultry meat products, resulting in huge economic loss to the industry. Even though gross and/or histologic characteristics of modern myopathies are similar to some of the known conditions, such as hereditary muscular dystrophy, nutritional myopathy, toxic myopathies, and marbling, WS and WB could have a different etiology. As a result, there is a need for future studies to identify markers for WS and WB in live birds and genetic, nutritional, and/or management strategies to alleviate the condition. © 2016 Poultry Science Association Inc.

Extending shelf life of poultry and red meat by irradiation processing

1993-01-01

Research has demonstrated that ionizing radiation can inactivate parasites, eliminate or greatly reduce the populations of microbial pathogens, and extend the shelf life while preserving the desired nutritional and sensory properties of refrigerated poultry and red meats. Foodborne pathogens can be greatly reduced in population and sometimes completely eliminated from foods by low doses of ionizing radiation. The shelf life of poultry, pork, and beef can be significantly extended by treatment with ionizing radiation. Combination treatments with vacuum packaging or modified atmosphere packaging and ionizing radiation have produced better than predicted results. Additional research is needed on the combined processes

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.

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.

The effect of high pressure processing at high temperature on texture and color of frankfurter-type sausages made with different contents of mechanically recovered poultry meat (MRPM) was evaluated and compared with that of a standard cooking process. Five types of sausages containing 100, 75, 50, 25, and 0% MRPM and 0, 25, 50, 75, and 100% of minced pork meat (MPM), respectively, were manufactured. They were pressurized at 500 MPa for 30 min at 50, 60, 70, and 75 C or cooked at 75 C for 30 min. Pressure-treated sausages were less springy and firm, but more cohesive. Moreover, color of pressurized sausages was lighter and more yellow than that of conventionally cooked sausages. Addition of MPM increased cohesiveness, hardness, and force at 80% compression. Minced pork meat also caused the appearance of sausages to be lighter, less red, and less yellow. Cooked sausages made with MRPM can have an attractive appearance and texture via high pressure processing.

Ahn, D.U.; Sell, J.L.; Jeffery, M.; Jo, C.; Chen, X.; Lee, J.I.

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

2008-10-01

The occurrence of Campylobacter spp. in a variety of foods from Ottawa, Ontario, Canada, and raw milk samples from across Canada was determined over a 2-year period. The samples consisted of 55 raw foods (chicken, pork, and beef), 126 raw milk samples from raw milk cheese manufacturers, and 135 ready-to-eat foods (meat products, salads, and raw milk cheeses). Campylobacter jejuni was detected in 4 of the 316 samples analyzed: 1 raw beef liver sample and 3 raw chicken samples. An isolation rate of 9.7% was observed among the raw chicken samples tested. This study also investigated the role of cross-contamination in disseminating Campylobacter from raw poultry within a food service operation specializing in poultry dishes. Accordingly, kitchen surfaces within a restaurant in Ottawa, Ontario, were sampled between March and August 2001. Tests of the sampling method indicated that as few as 100 Campylobacter cells could be detected if sampling was done within 45 min of inoculation; however, Campylobacter spp. were not detected in 125 swabs of surfaces within the kitchens of this food service operation. Despite the reported high prevalence of Campylobacter spp. in raw poultry, this organism was not detected on surfaces within a kitchen of a restaurant specializing in poultry dishes.

2008-03-01

Full Text Available Two experiments were conducted to evaluate the effects of dietary oxidized poultry offal fat on the performance of broilers and on the oxidative stability of dark chicken meat. One hundred and sixty male chicks were fed a corn-soybean meal diet containing 4% fresh or oxidized poultry fat from 10 to 47 days of age. Fresh fat was stored frozen until diets were produced, and oxidized fat was obtained by electrical heating (110 to 120 ºC. Birds were slaughtered at 47 days of age, and carcass characteristics were measured. Skinless and deboned thigh meat was stored chilled during 12 days, and samples were periodically collected to assess their quality and oxidative stability. Dietary oxidized fat did not affect bird performance or carcass characteristics. During chilled storage, meat color (L*, a* and b* was not affected by dietary treatments; however, TBARS (Thiobarbituric Acid Reactive Substances values were higher (P<0.05 in thigh meat from chickens fed the oxidized fat, indicating that oxidative stability was adversely affected.

2011-03-01

In this study, the possibility of extending shelf life of marinated poultry meat products by high pressure processing was evaluated. Relevant spoilage and pathogenic strains were selected and used as target microorganisms (MOs) for challenge experiments. Meat and brine were inoculated with MOs and treated at 450 MPa, 4 °C for 3 min. The results of inactivation show a decreasing pressure tolerance in the series Lactobacillus > Arcobacter > Carnobacterium > Bacillus cereus > Brochothrix thermosphacta > Listeria monocytogenes. Leuconostoc gelidum exhibited the highest pressure tolerance in meat. A protective effect of poultry meat was found for L. sakei and L. gelidum. In parallel, the influence of different marinade formulations (pH, carbonates, citrates) on protein structure changes during a pressure treatment was investigated. Addition of sodium carbonate shows a protection against denaturation of myofibrillar proteins and provides a maximum water-holding capacity. Caustic marinades allowed a higher retention of product characteristics than low-pH marinades.

2016-03-01

Full Text Available To create a concept of the marketing strategy, it is necessary to analyse the factors affecting the purchasing decisions of consumers. For the variables: production, import, export, and manufacturer's price we examine their impact on the marketing of poultry meat in the EU-28 in 2009 and 2011. Countries are grouped into clusters, their properties are analysed in relation to the mentioned variables. With multiple regression analysis, we find that there is a statistical correlation between high production and de-pending on the variable, and between the imports and exports as the independent vari-ables. Based on the analysed data in the researched countries, we conclude that the qualitative development of the production of poultry meat required implementing sophis-ticated agricultural policy with low inputs prices and exploit all available spare re-sources.

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.

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.

1993-01-01

Poultry meat and some vegetables, irradiated by 5 MeV electrons (0.1-4 kGy), were analysed by differential scanning calorimetry, from 24 h after irradiation. The temperature and enthalpy transitions of the water contained in the irradiated samples were measured and compared with those of unirradiated samples. The authors analysed 18 meat and 10 vegetable samples for each irradiation dose together with a similar number of unirradiated controls. The mean supercooling temperatures of water in the irradiated poultry meat samples and in some vegetables are significantly lower than those of controls. Moreover, the freezing enthalpies of the irradiated poultry breast are significantly lower than those of controls, while they are unchanged in the other cases. The mean ice melting temperatures and enthalpies are similar for all samples. The amount of the lowering of the water-ice transition depends on the nature of the sample and is highest in poultry breast and lowest in vegetables. (author)

2013-04-01

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.

Physico-chemical and microbiological properties of raw fermented sausages are not influenced by color differences of turkey breast meat.

Science.gov (United States)

Popp, J; Krischek, C; Janisch, S; Wicke, M; Klein, G

2013-05-01

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.

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.

Linear accelerators, commonly called Linacs, are being used for different industrial processes. This kind of machine produces high power electron beams and can treat many products with a high throughput. The main application of a Linac is the sterilization of medical disposable devices, polymerization and decontamination of food products. Salmonella commonly contaminates poultry. Thanks to E-beam treatment, it eradicates the pathogen quickly and permits the use of meat that should have been thrown away because of its infection. The world's first Linac dedicated to treat mechanically deboned poultry meat is located in Brittany at the Societe des Proteines Industrielles. It is a Thomson CSF Linac product, the CIRCE II, with an energy of 10 MeV and a power of 10 kW. This Linac has been used for more than 8 years, and its technology is fully proven. (author)

Supplying the energy demand in the chicken meat processing poultry with biogas

Directory of Open Access Journals (Sweden)

Adriano Henrique Ferrarez

2016-01-01

Full Text Available The main use of electrical energy in the chicken meat processing unit is refrigeration. About 70% of the electricity is consumed in the compressors for the refrigeration system. Through this study, the energetic viability of using biogas from poultry litter in supplying the demand for the refrigeration process was found. The meat processing unit studied has the potential to process about a hundred and sixty thousand chickens a day. The potential biogas production from poultry litter is 60,754,298.91 m3.year-1. There will be a surplus of approximately 8,103MWh per month of electric energy generated from biogas. An economic analysis was performed considering a planning horizon of 20 years and the discount rate of 12% per year. The economic analysis was performed considering scenario 1: sale of all electricity generated by the thermoelectric facility, and scenario 2: sale of the surplus electricity generated after complying with the demands of the refrigeration process and all other electrical energy and thermal energy use. Economic indicators obtained for scenarios 1 and 2 were favorable for the project implementation.

2015-01-15

The occurrence of pathogenic strains in poultry meat is of growing concern in Romania. Another problem found on a global level is the continuous increase of antimicrobial resistance in bacteria isolated from food. This study aimed to evaluate the prevalence of pathogenic bacteria in poultry carcasses obtained in Romania in 2012-2013 and to reveal the most prevalent patterns of antimicrobial resistance in the isolated strains. A total of 144 broiler chicken carcasses were evaluated according to classical microbiological methods. The DNA was extracted from the bacterial colonies and the resistance genes were identified by PCR. In 2012, 47.2% of the samples revealed at least one of the following bacteria: Campylobacter jejuni (9.72%; n = 7), Salmonella enterica serotype Enteritidis (4.17%; n = 3), Listeria monocytogenes (15.28%; n = 11), and Escherichia coli (16.67%; n = 12). In 2013, the number of positive samples of pathogenic bacteria decreased, although Campylobacter jejuni was isolated in a higher percentage (20.8% vs. 9.72%). The percentage of multidrug-resistant (MDR) bacteria was high (23%); the most prevalent pattern included resistance to tetracycline, sulfonamides, and quinolones/fluoroquinolones. All the resistant Salmonella and E. coli strains were tested for the presence of characteristic resistance genes (Kn, bla(TEM), tetA, tetB, tetG, DfrIa, aadA1a, Sul) and revealed that these isolates represent an important reservoir in the spread of this phenomenon. Our findings suggest that Romania urgently needs an integrated surveillance system within the entire chain, for drug-resistant pathogens isolated from poultry meat.

Lupton, Sara J; Hakk, Heldur

2017-09-01

Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants whose use has contaminated foods and caused subsequent human exposures. To address the issue of possible human exposure, samples from a 2012-13 US meat and poultry (beef, pork, chicken, turkey) study were analysed for seven PBDEs. The mean summed concentrations of the seven BDE congeners (ΣPBDE) from beef, pork, chicken and turkey were 0.40, 0.36, 0.19, and 0.76 ng g -1 lipid weight (lw). The range of ΣPBDEs for all meat classes was 0.01-15.78 ng g -1 lw. A comparison of this study with a 2007-08 study revealed a decline in the median ΣPBDEs for all four meat classes, a reduction of 25.9% to 70.0%, with pork, chicken and turkey PBDE residues being statistically lower relative to the 2007-08 study. BDEs 47 and 99 contributed the most to the ΣPBDE concentrations, indicating likely animal exposures to the penta-BDE formulation. Based on the reported data an estimate of US consumer daily intake of PBDEs from meat and poultry was 6.42 ng day -1 .

Prospects and challenges of radiation processing of meats and meat products in India

International Nuclear Information System (INIS)

Chander, Ramesh

2014-01-01

In India goat, lamb and chicken meat are widely preferred, while, bovine meat and pork are consumed only by a small segment of the population. Meats in the country are mainly marketed fresh or in frozen state. Recently chilled poultry has been introduced in Indian market. In addition to fresh meats, several other ready to eat or ready to cook meat products like chicken chilly, chicken tikka, mutton shammi kababs, mutton seekh kababs etc are available in urban Indian market. These products are marketed only in the frozen state and have limited market due to expensive and inadequate freezing facilities. Major share of domestic fresh meat and poultry market is by unorganized sector and only a few corporate houses like Godrej and Venkey's are marketing poultry products. The time has come to benefit from radiation processing for safe, chilled meat and poultry in India. Shelf-stable, nutritious meat and meat products can also be produced by the process. Radiation processing of these foods will be of great economic and health significance and give boost to exports. This radiation processing can meet the needs of services of convenient and ready-to-eat meat and meat products

Background The significant role of retail poultry meat as an important exposure pathway for the acquisition and transmission of extended spectrum ?-lactamase-producing Escherichia coli (ESBL-EC) into the human population warrants understanding concerning those operational practices associated with dissemination of ESBL-EC in poultry meat retailing. Hence, the objective of this study was to determine the prevalence, spatial distribution and potential risk factors associated with the disseminat...

Escherichia coli and urinary tract infections: the role of poultry-meat.

Extraintestinal pathogenic Escherichia coli (ExPEC) is the most common cause of community-acquired and hospital-acquired extraintestinal infections. The hypothesis that human ExPEC may have a food animal reservoir has been a topic of investigation by multiple groups around the world. Experimental studies showing the shared pathogenic potential of human ExPEC and avian pathogenic E. coli suggest that these extraintestinal E. coli may be derived from the same bacterial lineages or share common evolutionary roots. The consistent observation of specific human ExPEC lineages in poultry or poultry products, and rarely in other meat commodities, supports the hypothesis that there may be a poultry reservoir for human ExPEC. The time lag between human ExPEC acquisition (in the intestine) and infection is the fundamental challenge facing studies attempting to attribute ExPEC transmission to poultry or other environmental sources. Even whole genome sequencing efforts to address attribution will struggle with defining meaningful genetic relationships outside of a discrete food-borne outbreak setting. However, if even a fraction of all human ExPEC infections, especially antimicrobial-resistant ExPEC infections, is attributable to the introduction of multidrug-resistant ExPEC lineages through contaminated food product(s), the relevance to public health, food animal production and food safety will be significant.

Full Text Available Background: In this study, a method for determination of tetracycline (TC residues in poultry with the help of high-performance liquid chromatography technique was validated. Materials and Methods: The principle step involved in ultrasonic-assisted extraction of TCs from poultry samples by 2 ml of 20% trichloroacetic acid and phosphate buffer (pH 4, which gave a clearer supernatant and high recovery, followed by centrifugation and purification by using 0.22 μm filter paper. Results: Validity study of the method revealed that all obtained calibration curves showed good linearity (r2 > 0.999 over the range of 40-4500 ng. Sensitivity was found to be 1.54 and 1.80 ng for oxytetracycline (OTC and TC. Accuracy was in the range of 87.94-96.20% and 72.40-79.84% for meat. Precision was lower than 10% in all cases indicating that the method can be used as a validated method. Limit of detection was found to be 4.8 and 5.10 ng for OTC and TC, respectively. The corresponding values of limit of quantitation were 11 and 12 ng. Conclusion: The method reliably identifies and quantifies the selected TC and OTC in the reconstituted poultry meat in the low and sub-nanogram range and can be applied in any laboratory.

Observational studies on the association between white meat (including fish and poultry) intake and the risk of colorectal adenoma (CRA), the precursor of colorectal cancer, have reported mixed results. To provide a quantitative assessment of this association, we summarized the evidence from observational studies. Relevant studies published on or before April 30, 2012 were identified from MEDLINE and EMBASE. Summary effect size estimates with 95% confidence intervals (CIs) were calculated with a random-effects model. Between-study heterogeneity was assessed using the Cochran Q and I(2) statistics. A total of 23 publications from 21 independent studies (16 case-control and 5 cohort studies) were included in this meta-analysis. Based on high versus low analysis, the summary effect size estimate of CRA was 0.96 (95% CI, 0.84-1.09) for white meat intake, 0.98 (95% CI, 0.80-1.19) for fish intake, and 0.98 (95% CI, 0.80-1.18) for poultry intake. Subgroup analyses revealed that the null associations of CRA with intake of white meat (fish/poultry) were independent of geographic locations, study design, type of food frequency questionnaire, number of cases, and adjustments for confounders, such as body mass index, use of nonsteroidal anti-inflammatory drugs, dietary energy intake, smoking, and physical activity. Intake of white meat (fish/poultry) is not associated with the risk of CRA. Copyright © 2013 Elsevier Inc. All rights reserved.

The burden of food-borne diseases still represents a threat to public health; in 2012, the domestic setting accounted for 57.6% of strong-evidence EU food-borne Salmonella outbreaks. Next to cross-contamination, inadequate cooking procedure is considered as one of the most important factors contributing to food-borne illness. The few studies which have assessed the effect of domestic cooking on the presence and numbers of pathogens in different types of meat have shown that consumer-style cooking methods can allow bacteria to survive and that the probability of eating home-cooked poultry meat that still contains surviving bacteria after heating is higher than previously assumed. Thus, the main purpose of this study was to reproduce and assess the effect of several types of cooking treatments (according to label instructions and not following label instructions) on the presence and numbers of Salmonella Typhimurium DT 104 artificially inoculated in five types of poultry-based meat preparations (burgers, sausages, ready-to-cook-kebabs, quail roulades and extruded roulades) that are likely to be contaminated by Salmonella. Three contamination levels (10 cfu/g; 100 cfu/g and 1000 cfu/g) and three cooking techniques (grilling, frying and baking) were applied. Cooking treatments performed according to label instructions eliminated Salmonella Typhimurium (absence per 25g) for contamination levels of 10 and 100 cfu/g but not for contamination levels of 1000 cfu/g. After improper cooking, 26 out of 78 samples were Salmonella-positive, and 23 out of these 26 samples were artificially contaminated with bacterial loads between 100 and 1000 cfu/g. Nine out of 26 samples provided quantifiable results with a minimum level of 1.4MPN/g in kebabs (initial inoculum level: 100 cfu/g) after grilling and a maximum level of 170MPN/g recorded in sausages (initial inoculum level: 1000 cfu/g) after grilling. Kebabs were the most common Salmonella-positive meat product after cooking

Full Text Available Abstract Food Business Operators (FBO are responsible for the safety of the food they produce and in Ireland those under the regulatory control of the Department of Agriculture, Food and Marine are required to provide summary data on microbiological tests undertaken as part of their food safety controls. These data are provided to the National Reference Laboratory through the 25 private laboratories undertaking the testing. Results Over the five-year period Salmonella sp. was isolated from 0.7% of the 254,000 raw meat or raw meat products tested with the annual prevalence ranging from 0.5 to 1.1%. Poultry meats were consistently more contaminated than other meats with higher recovery rates in turkey (3.3%, duck (3.3%, and chicken (2.5% compared with meats of porcine (1.6%, ovine (0.2% and bovine origin (0.1%. Salmonella sp. was also isolated from 58 (0.06% of the 96,115 cooked or partially cooked meat and meat products tested during the reporting period with the annual percentage positive samples ranging from 0.01 to 0.16%. A total of 50 different serotypes were recovered from raw meats over this period with the greatest diversity found in poultry samples (n = 36. Four serotypes, Kentucky, Typhimurium, Agona and Derby accounted for over 70% of all isolates detected on FBO testing over the period 2005 to 2009. Conclusions Capturing microbiological data generated by Food Business Operators allows the regulatory sector access to a substantial amount of valuable data with the minimum financial outlay.

The transportation of poultry and related products for international trade contributes to transboundary pathogen spread and disease outbreaks worldwide. To prevent pathogen incursion through poultry products, many countries have regulations about animal health and poultry product quarantine. However, in Japan, animal products have been illegally introduced into the country in baggage and confiscated at the airport. Lately, the number of illegally imported poultry and the incursion risk of transboundary pathogens through poultry products have been increasing. In this study, we isolated avian influenza viruses (AIVs) from raw poultry products illegally imported to Japan by international passengers. Highly (H5N1 and H5N6) and low (H9N2 and H1N2) pathogenic AIVs were isolated from raw chicken and duck products carried by flight passengers. H5 and H9 isolates were phylogenetically closely related to viruses isolated from poultry in China, and haemagglutinin genes of H5N1 and H5N6 isolates belonged to clades 2.3.2.1c and 2.3.4.4, respectively. Experimental infections of H5 and H9 isolates in chickens and ducks demonstrated pathogenicity and tissue tropism to skeletal muscles. To prevent virus incursion by poultry products, it is important to encourage the phased cleaning based on the disease control and eradication and promote the reduction in contamination risk in animal products. © 2017 Blackwell Verlag GmbH.

Thermophilic Campylobacter spp. are one of the primary causes of bacterial human diarrhea. The consumption of poultry meats, by-products, or both is suspected to be a major cause of human campylobacteriosis. The aims of this study were to determine the prevalence of thermophilic Campylobacter spp. in fresh poultry meat and poultry by-products by conventional culture methods and to confirm Campylobacter jejuni and Campylobacter coli isolates by using the multiplex PCR assay. Two hundred fifty fresh poultry samples were collected from a variety of supermarkets and slaughterhouses located in Sfax, Tunisia, including chicken (n =149) and turkey (n =101). The samples were analyzed using conventional microbiological examinations according to the 2006 International Organization for Standardization method (ISO 10272-1) for Campylobacter spp. Concurrently, a real-time PCR was used for identification of C. jejuni and C. coli . Of the 250 samples of poultry meat and poultry by-products, 25.6% (n = 64) were contaminated with Campylobacter spp. The highest prevalence of Campylobacter spp. was found in chicken meat (26.8%) followed by turkey meat (23.7%). Among the different products, poultry breasts showed the highest contamination (36.6%) followed by poultry by-products (30%), poultry wings (28%) and poultry legs (26%) showed the lowest contamination, and no contamination was found on neck skin. Of the 64 thermophilic Campylobacter isolates, C. jejuni (59.7%) was the most frequently isolated species and 10.9% of the isolates were identified as C. coli . All of the 64 Campylobacter isolates identified by the conventional culture methods were further confirmed by PCR. The seasonal peak of Campylobacter spp. contamination was in the warm seasons (spring and summer). The study concluded that high proportions of poultry meat and poultry by-products marketed in Tunisia are contaminated by Campylobacter spp. Furthermore, to ensure food safety, poultry meats must be properly cooked

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.

Full Text Available Campylobacter spp. are bacterial pathogens associated with human gastroenteritis worldwide. In Europe, campylobacteriosis is one of the leading food-borne bacterial diseases and the consumption of poultry meats is suspected to be one of the major causes of illness. The aim of our research was to determine the number of Campylobacter spp. in poultry carcasses and in poultry meat samples during their storage till to retail markets. The study was conducted from February 2009 to February 2010 at slaughterhouse in Veneto region, followed by a test of fresh poultry meat placed on the market for sale. A total of 90 poultry carcass and 90 samples of poultry meat were examined. The quantitative examination resulted in Campylobacter spp. counts (mean: for carcasses between 2,0 ∙101 ufc/g and 1,5 ∙103 ufc/g (4,2 ∙102 and poultry meat between 2,0 ∙101 ufc/g and 3,7 ∙102 ufc/g (8,1 ∙101. The majority of isolates were classified as Campylobacter jejuni (58,3%, Campylobacter coli (22,9% or Arcobacter cryaerophilus (4,2%.

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.

Vegetarian diets are defined by the absence of meat and fish, but differences in the intake of other foods between meat-eaters and low or non-meat eaters are also important to document. We examined intakes of high-protein foods (meat, poultry, fish, legumes, nuts, vegetarian protein alternatives, dairy products, and eggs) and other major food groups (fruit, vegetables, bread, pasta, rice, snack foods, and beverages) in regular meat-eaters, low meat-eaters, poultry-eaters, fish-eaters, vegetarians, and vegans of white ethnicity participating in UK Biobank who had completed at least one web-based 24-h dietary assessment (n = 199,944). In regular meat-eaters, around 25% of total energy came from meat, fish, dairy and plant milk, cheese, yogurt, and eggs. In vegetarians, around 20% of energy came from dairy and plant milk, cheese, yoghurt, eggs, legumes, nuts, and vegetarian protein alternatives, and in vegans around 15% came from plant milk, legumes, vegetarian alternatives, and nuts. Low and non-meat eaters had higher intakes of fruit and vegetables and lower intakes of roast or fried potatoes compared to regular meat-eaters. The differences in the intakes of meat, plant-based high-protein foods, and other foods between meat-eaters and low and non-meat eaters in UK Biobank may contribute to differences in health outcomes.

Antibiotic use in animal husbandry has raised concerns on the spread of resistant bacteria. Currently animal products are traded globally with unprecedented ease, which has been challenging the control of antimicrobial resistance. This study aims to detect and characterize extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae from imported and locally produced poultry products sold in Ghana. Local and imported chicken meat was collected from 94 stores and markets throughout Kumasi (Ghana) and cultured on selective ESBL screening agar. Phenotypic ESBL-producing E. coli and K. pneumoniae isolates were confirmed by combined disc test and further characterized by antibiotic susceptibility testing, amplification of the bla CTX-M , bla TEM and bla SHV genes as well as multilocus sequence typing (MLST) and linked to the country of origin. Out of 200 meat samples, 71 (36%) samples revealed 81 ESBL-producing isolates (46 E. coli and 35 K. pneumoniae), with 44% (30/68) of local poultry and 31% (41/132) of imported products being contaminated. Most ESBL-producing isolates harboured the bla CTX-M-15 gene (61/81, 75%) and the dominant Sequence Types (ST) were ST2570 (7/35, 20%) among K. pneumoniae and ST10 (5/46, 11%) among E. coli. High numbers of ESBL-producing bacteria, particularly on local but also imported poultry meat, represent a potential source for human colonization and infection as well as spread within the community. Surveillance along the poultry production-food-consumer chain would be a valuable tool to identify sources of emerging multidrug resistant pathogens in Ghana. Copyright © 2018 Elsevier B.V.

da Silva, Débora Cristina Fernandes; de Arruda, Alex Martins Varela; Gonçalves, Alex Augusto

2017-06-01

The aim of this study was to determine and compare the quality parameters of broiler chicken meat from free-range and industrial poultry system. Proximate composition, color, pH, shear force, microbial quality and sensory characteristics were evaluated. Both free-range and industrial chicken meat presented PSE (pale, soft and exudative) anomaly ( L * > 53). An inverse correlation between lightness, pH and shear force was observed. The free range broiler meat had higher yellow color ( b * 11.56) and shear force (2.75 kgf) and lower red color ( a * 1.65) and pH (5.75) in comparison to the industrial broiler meat, due intensive physical activity on growing phase and influence of the pre-slaughter stress on the rigor mortis. The thigh cut from free range broiler meat showed higher protein levels (18.00%), while to the thigh and drumstick cuts of industrial broiler meat showed higher total fat levels (3.4 and 5.0%, respectively). In general, each strain and chickens producing methods gave the peculiar characteristics to meat (chemical, physical, microbiological and sensorial).

Monge, María Del Pilar; Magnoli, Carina Elizabeth; Chiacchiera, Stella Maris

2012-05-01

The aims of the present work were: (1) to determine both mycobiota in raw materials and finisher poultry feed, as well as the ability to produce aflatoxin B1 by A. flavus strains, and (2) to evaluate the natural co-occurrence of aflatoxins (AFs), fumonisins (FBs), gliotoxin, diacetoxyscirpenol (DAS), HT-2 toxin, and T-2 toxin in poultry feed by LC-MS/MS. Nineteen percent of raw materials and 79% of finisher poultry feed samples exceeded the maximum allowed total fungal count (1 × 10(4) CFU g(-1)) to ensure hygienic quality. Aspergillus flavus was the only species belonging to section Flavi which was isolated while Fusarium verticilliodes was the prevalent species. Forty-seven percent of A. flavus strains were aflatoxin B1 producers and the highest frequency of aflatoxigenic strains was isolated from finisher poultry feeds. Principal component analysis showed that corn grains are closely related with total fungal and Fusarium counts. This positive relationship suggests that total fungal and Fusarium spp. counts in poultry feed might come mainly from corn grains. Regarding poultry feeds, in ground finisher type, Aspergillus spp. counts increased as water activity (aw) diminished. A positive relationship among aw, total fungal and Fusarium spp. counts was observed in both ground finisher and ground starter feed. Several mycotoxins were monitored in feeds by applying the LC MS/MS technique. One hundred percent of poultry samples were contaminated with FB1, and the highest levels were detected in pelleted finisher poultry. AFB1, gliotoxin, DAS, HT-2 toxin, and T-2 toxin were not detected in any poultry feed. The scarcity of available mycotoxicological studies from Argentinean poultry feed using a multitoxin analysis technique enhances the contribution of the findings of this report.

This study was performed to determine the prevalence, antimicrobial susceptibility, and genetic relatedness of Salmonella enterica subsp. enterica and Campylobacter spp. in poultry meat, and to analyze the association of genetic types of these bacteria with their geographical distribution and antimicrobial resistance profiles. Salmonella and Campylobacter isolates have been detected, respectively, in 54 and 71 samples out of 100 samples tested. Nine Salmonella serotypes were found, including S. enterica subsp. enterica serovar Infantis (33%), Schwarzengrund (12%), Manhattan (9%), and others. Campylobacter jejuni and C. coli were detected in 64 (64%) and 14 (14%) samples, respectively. S. enterica subsp. enterica isolates were very frequently resistant to tetracycline (78.3%) and streptomycin (68.3%). Many C. jejuni and C. coli isolates were resistant to sulfamethoxazole/trimethoprim (90.5%), nalidixic acid (47.3%), ampicillin (45.9%), and ciprofloxacin (40.5%). Cluster analysis was performed for the Salmonella isolates using pulsed-field gel electrophoresis (PFGE) data. For Campylobacter isolates, the cluster analysis was based on both PFGE and comparative genomic fingerprinting. The molecular typing results were compared with the information about antimicrobial resistance and geographical locations in which the poultry meat was produced. This analysis revealed that C. jejuni strains with a particular genotype and antimicrobial resistance profile are spreading in specific areas of Japan.

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.

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.

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.

Roxarsone (rox), an arsenic (As) containing organic compound, is a common feed additive used in poultry production. To determine if As present in rox is excreted into the poultry litter without any retention in chicken meat for safe human consumption, the transference of As from the feed to poultry excreta was assessed using two commercial chicken strains fed with and without dietary rox. The results revealed that both the strains had similar behaviour in growth (chicken weight; 2.17-2.25kg), feed consumption (282-300kgpen -1 initially containing 102 chicken) and poultry litter production (73-81kgpen -1 ) during the growth phase of 35days. Our mass balance calculations showed that chickens ingested 2669-2730mg As with the feed and excreted out 2362-2896mg As in poultry litter during the growth period of 28days when As containing feed was used, yielding As recovery between 86 and 108%. Though our complementary studies show that residual arsenic species in rox-fed chicken meat may have relevance to human exposure, insignificant retention of total As in the chicken meat substantiates our mass balance results. The results are important in evaluating the fate of feed additive used in poultry production and its potential environmental implications if As containing poultry litter is applied to soil for crop production.

Full Text Available Mozambican poultry industry might be an option to facilitate people's access to animal protein, as well as to reduce the dependence on imports of the product, bringing jobs and income forth. This study aimed to characterize and to analyze the competitiveness of poultry industry in Mozambique. Porter’s Five Forces Model, which focuses on the five strengths that shape business competition, was applied. The results show a low level of competition within the industry, a limited supply of raw material and the fact that national products are commodities and competes with strong foreign participants. Domestic demand for chicken meat is increasing, but buyers base their decision mainly on price. Challenges include establishment of governance structure and policies for poultry sector and consumer welfare. Another alternative to improve the poultry industry in Mozambique is to promote technical cooperation with other countries, such as Brazil, in order to acquire specific structures for chicken production, genetic material and adequate nutrition.

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.

1999-01-01

The mean activity concentrations of the naturally occurring radionuclides ( 226 Ra, 228 Ra and 40 K) in three types of meat (goat meat, beef and pork) from stock animals as well as free-range and intensive poultry raised within the OAU environment of the Obafemi Awolowo University (OAU), Ile-Ife, were measured by means of a well-calibrated high-purity germanium detector. The specific activities of 226 Ra in the three types of meat ranged from 1.11 to 5.83 Bq kg -1 with a mean of 3.10±1.52 Bq kg -1 . 228 Ra was not detectable in both beef and pork but had a range of 1.53-1.63 Bq kg -1 with a mean of 1.58±0.30 Bq kg -1 in goat meat while 40 K recorded an average specific activity of 360.00±54.20 Bq kg -1 for the various samples of meat. The mean activity values of 226 Ra, 228 Ra and 40 K for the poultry were 2.59±0.48, 0.78±0.13 and 265.01±15.90 Bq kg -1 , respectively. The results obtained for the daily radionuclide intake of the various meat types showed that those of 226 Ra ranged from 0.4 to 8.1 mBq d -1 with a mean of 4.9±0.4 mBq d -1 . Since 228 Ra was not detectable in beef and pork its daily intake could not be estimated. However, a mean value of intake of 2.2±0.4 mBq d -1 was obtained for goat meat. The values of 40 K intake ranged from 150.0 to 672.7 mBq d -1 with an average of 455.5±19.0 mBq d -1 . The mean daily intakes of 226 Ra, 228 Ra and 40 K for the two types of poultry were 6.15±0.70, 1.9±0.3 and 633.4±38.0 mBq d -1 , respectively

The objective of this study was to investigate a clonal relationship among thermotolerant Campylobacter spp. isolates from different stages of the poultry meat supply chain in Argentina. A total of 128 thermotolerant Campylobacter spp. (89 C. jejuni and 39 C. coli) isolates from six poultry meat chains were examined. These isolates were from: a) hens from breeder flocks, b) chickens on the farm (at ages 1 wk and 5 wk), c) chicken carcasses in the slaughterhouse, and d) chicken carcasses in the retail market. Chickens sampled along each food chain were from the same batch. Campylobacter spp. isolates were analyzed using pulsed-field gel electrophoresis to compare different profiles according to the source. Clustering of C. jejuni isolates resulted in 17 profiles, with four predominant genotypes and many small profiles with just a few isolates or unique patterns, showing a very high degree of heterogeneity among the C. jejuni isolates. Some clusters included isolates from different stages within the same chain, which would indicate a spread of strains along the same poultry meat chain. Moreover, twenty-two strains of C. coli clustered in seven groups and the remaining 17 isolates exhibited unique profiles. Evidence for transmission of thermotolerant Campylobacter spp. through the food chain and cross contamination in the slaughterhouses were obtained. This collective evidence should be considered as the scientific basis to implement risk management measures to protect the public health. Copyright © 2017 Asociación Argentina de Microbiología.

Full Text Available Poultry production in eastern Croatia is developed by individual producers mainly in semi intensive way, and within the organized poultry systems where the process is organized in a modern, intensive way. There is a tradition of breeding hens and geese in this area. Poultry products - meat and eggs are important in supplying the population with animal protein, minerals and vitamins. Modern hybrid hens are used for egg production and for meat production in the intensive production. Today geese breeding in these areas are completely neglected. Croatia as a member of European Union, has possibility of the placement of autochthonous breeds of poultry such as Hrvatica hen, Zagorje turkey and Podravian goose. Financial supports at the national level are allocated for the first two autochthonous breeds of poultry because these breeds can, with good production traits, represent genetic resources and strategic reserves in the future development of domestic poultry genotypes. Poultry production is especial emphasis in accordance with the criteria of welfare and health of poultry. This paper discusses further development of poultry in terms of production of poultry meat and eggs as a functional food. The composition and content of nutricines in meat and eggs can be affected by feed composition. Desired nutricines are installed in muscular tissue of poultry by using feed and adding some components. Consumption of eggs and poultry meat enriched by selenium, lutein and omega-3 fatty acids affects the improvement of the quality of the human diet. The recent researches show that chicken can effectively be enriched in carnosine - ingredients that are now taught as “anti-aging” factor. Enrichment of poultry products with nutricines gives greater importance to these foods in the diet of the population than the former one, mainly based on the nutritional aspect. Greater selection of quality poultry products can be a significant factor in the development of

The significant role of retail poultry meat as an important exposure pathway for the acquisition and transmission of extended spectrum β-lactamase-producing Escherichia coli (ESBL-EC) into the human population warrants understanding concerning those operational practices associated with dissemination of ESBL-EC in poultry meat retailing. Hence, the objective of this study was to determine the prevalence, spatial distribution and potential risk factors associated with the dissemination of ESBL-EC in poultry meat retail at wet-markets in Selangor, Malaysia. Poultry meat (breast, wing, thigh, and keel) as well as the contact surfaces of weighing scales and cutting boards were sampled to detect ESBL-EC by using culture and disk combination methods and polymerase chain reaction assays. Besides, questionnaire was used to obtain data and information pertaining to those operational practices that may possibly explain the occurrence of ESBL-EC. The data were analysed using logistic regression analysis at 95 % CI. The overall prevalence of ESBL-EC was 48.8 % (95 % CI, 42 - 55 %). Among the risk factors that were explored, type of countertop, sanitation of the stall environment, source of cleaning water, and type of cutting board were found to be significantly associated with the presence of ESBL-EC. Thus, in order to prevent or reduce the presence of ESBL-EC and other contaminants at the retail-outlet, there is a need to design a process control system based on the current prevailing practices in order to reduce cross contamination, as well as to improve food safety and consumer health.

2014-01-01

Full Text Available The objective of this study was to begin characterizing purchase, storage, handling, and preparation of poultry products and eggs by selected consumers in three Asian countries: India, Korea, and Thailand. Approximately 100 consumers in each location were recruited to participate in this study. The consumers were surveyed about eggs and poultry purchase behavior characteristics, such as temperatures and locations, storage behavior, such as storage locations in the refrigerator or freezer, preparation behavior, such as washing eggs and poultry before cooking, and handling behavior, such as using cutting boards during cooking. The results indicated differences in purchase and storage practices of raw eggs. Most Korean consumers purchased refrigerated eggs and stored the eggs in the refrigerator, while Indian and Thai consumers bought eggs that were stored at room temperature, but would refrigerate the eggs at home. Approximately half of the consumers in each country froze raw meat, poultry, or seafood. Food preparation practices showed potential for cross-contamination during cooking, such as using the same cutting board for different kinds of foods or not washing hands with soap and water. The results presented in this pilot study may lead to development of educational messages and raising consumer awareness of food safety practices in Asian countries.

2015-07-01

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

2012-01-01

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.

This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batter, were produced and analyzed for pH, proximal composition, calcium and residual nitrite content, water activity, 2-thiobarbituric acid reactive substances (TBARS), instrumental color and texture profile. The sensory profile of the mortadella's was also evaluated by acceptance test and check-all-that-applies (CATA) analysis. The MDPM addition increased (p<0.05) fat, residual nitrite and calcium content in the all sausage formulations, but mutton sausage had (p<0.05) higher fat and lower moisture content than lamb sausage. The pH, water activity, TBARS index and color was not affected by MDPM additions, while the mutton sausages were significantly redder (higher a *, C *, and lower h °) and darker (lower L *) than lamb sausages. Adding up to 60% of MDPM reduced (p<0.05) sausages hardness and chewiness. Overall, the meat replacement by MDPM increased the sausages acceptance, but the mutton sausage with 30% of MDPM replacer were the most preferred. Consumers related that pink color, glossy appearance, poultry meat-like taste, soft texture, juicy and greasy mouth feel to all sausages contain MDPM according to CATA analysis. Mutton from culled ewes can be utilized for mortadella production with 30% replacement of lean mutton and fat by MDPM.

The data were analysed using logistic regression analysis at 95 % CI. Results The overall prevalence of ESBL-EC was 48.8 % (95 % CI, 42 – 55 %. Among the risk factors that were explored, type of countertop, sanitation of the stall environment, source of cleaning water, and type of cutting board were found to be significantly associated with the presence of ESBL-EC. Conclusions Thus, in order to prevent or reduce the presence of ESBL-EC and other contaminants at the retail-outlet, there is a need to design a process control system based on the current prevailing practices in order to reduce cross contamination, as well as to improve food safety and consumer health.

The U.S. Food Safety and Inspection Service (FSIS) tests sets of samples of selected raw meat and poultry products for Salmonella to ensure that federally inspected establishments meet performance standards defined in the pathogen reduction-hazard analysis and critical control point system (PR-HACCP) final rule. In the present report, sample set results are described and associations between set failure and set and establishment characteristics are identified for 4,607 sample sets collected from 1998 through 2003. Sample sets were obtained from seven product classes: broiler chicken carcasses (n = 1,010), cow and bull carcasses (n = 240), market hog carcasses (n = 560), steer and heifer carcasses (n = 123), ground beef (n = 2,527), ground chicken (n = 31), and ground turkey (n = 116). Of these 4,607 sample sets, 92% (4,255) were collected as part of random testing efforts (A sets), and 93% (4,166) passed. However, the percentage of positive samples relative to the maximum number of positive results allowable in a set increased over time for broilers but decreased or stayed the same for the other product classes. Three factors associated with set failure were identified: establishment size, product class, and year. Set failures were more likely early in the testing program (relative to 2003). Small and very small establishments were more likely to fail than large ones. Set failure was less likely in ground beef than in other product classes. Despite an overall decline in set failures through 2003, these results highlight the need for continued vigilance to reduce Salmonella contamination in broiler chicken and continued implementation of programs designed to assist small and very small establishments with PR-HACCP compliance issues.

Devatkal, Suresh K; Naveena, B M

2010-06-01

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.

Listeriosis is a disease that causes septicemia or encephalitis in humans, animals and birds. Although, the disease is rare and sporadic in poultry but if occurs then causes septicemia or sometimes localized encephalitis. Occasionally, the disease is seen in young chicks and the causative agent, like in humans and animals, is Listeria monocytogenes. The organism is capable to infect almost all animals and poultry; however, outbreaks of listeriosis are infrequent in birds. It is widely distributed among avian species and chickens, turkeys, waterfowl (geese, ducks), game birds, pigeons, parrots, wood grouse, snowy owl, eagle, canaries, which appear to be the most commonly affected. Chickens are thought to be the carriers of Listeria and also the prime reservoirs for the infection and thus contaminate the litter and environment of the poultry production units. Listeriosis is often noticed along with other poultry diseases such as coccidiosis, infectious coryza, salmonellosis, campylobacteriosis and parasitic infections, signifying the opportunistic nature of the organism. Intestinal colonization of poultry and the presence of L. monocytogenes in feces represent a potential source of the organism for listeriosis in ruminants. Man gets infection from raw broiler meat due to Listeria contamination and unhygienic conditions of the processing area, rather than acquiring direct infection from birds. With the changing food habits of the people, the health consciousness is also increasing and since listeriosis has now been recognized as an emerging food borne zoonoses. Therefore, this review has been compiled to make aware the poultry producers and the consumers of poultry meat/products regarding the importance of the disease and its public health significance.

The significance of Campylobacter jejuni infection in poultry: a review.

Science.gov (United States)

Shane, S M

1992-01-01

Campylobacter is a significant cause of enterocolitis in consumers of undercooked poultry meat. Campylobacter jejuni is the most significant of the three thermophilic Campylobacter species, and is responsible for intestinal colonization in poultry and food-borne enteritis in humans. Generally, C. jejuni is apathogenic in poultry, although newly hatched chicks and turkeys may develop a transient diarrhoea following infection. Modern intensive poultry production favours the introduction of infection into commercial growing units, resulting in intestinal colonization during the second to fourth weeks inclusive. Routes of infection include contaminated fomites, infected water supply, rodents, insects, and free-living birds. Vertical transmission is considered unlikely. Contamination of poultry meat is enhanced by deficiencies in transport and processing of broilers and turkeys. Scalding, defeathering and evisceration represent the significant points of cross-contamination during processing. Epidemiological correlation has been established between consumption of contaminated chicken and outbreaks of human campylobacteriosis. Amelioration of infection by application of improved standards of hygiene and decontamination is possible in the context of commercial poultry production. Improvement in washing of carcasses, and the application of chemical disinfectants and gamma irradiation have the potential to reduce the prevalence of C. jejuni contamination in poultry meat. These innovations, together with improved storage and handling of meat products, will reduce the risk of campylobacteriosis to consumers.

2010-01-01

Full Text Available Examinations were conducted in terms of microbiological quality/quantity (TMC, Coliforms, E. coli, S. aureus, Sulphate-reducing Clostridia, B. cereus, Salmonella spp. and Lysteria spp. and Campylobacter spp. on 240 poultry meat samples (chicken, turkey and quail acquired pursuant to the standards set by the Regional Plan of programming and coordination in the field of operations concerning official inspections of Lombardia animal origin and by a few private companies for self-inspection. The TMC was consistently low and in line with reports in the literature, as was the case with coliforms, E. coli, S. aureus, sulphatereducing Clostrides and B. cereus. In the case of Salmonella spp., only 5 samples tested positive: one for S. typhimurium and one for S. enteritidis (chicken; only one sample from turkey tested positive for S. blokley, and two out of five samples analysed from quail tested positive result for S. typhimurium. About 3% of the samples analyzed tested positive for Listeria monocitogenes, but they were within the legal limits. Research on Campylobacter thermophiles has involved only 50 samples, of which only 5 have tested positive. These results confirm the high quality of hygiene and cleanliness of poultry meat, in accordance with that reported in the national literature and with respect to EU norms.

Full Text Available The aim of this study was to observe the effectiveness of disinfection on a broiler farm and in a plant processing the poultry from this farm. The broiler farm was disinfected with a preparation based on peracetic acid while a preparation based on quarternary ammonium salt was used in the processing plant. We evaluated swabs taken from surfaces, which come into contact with broilers and broiler meat. Results of the swabs taken by standard microbiological swabbing method were evaluated with results of the swabs taken by the ATP-bioluminescence method. The microbiological examination included total counts of microorganisms, coliform count and moulds. When using the standard plate counts method on the broiler farm we found that the plate counts in 0% of swabs were 100 CFU. In the processing plant, out of 22% of swabs 100. The bioluminescence method was applied only in the processing plant where 300 RLU were measured in 80, 10 and 10% of swabs, resp. Our observations and results allowed us to conclude that the disinfectants tested appeared suitable for the respective premises and the ATP bioluminescence method could be use as a as a suitable complement for detection of cleanliness of individual surfaces.

Comminuted sausages formulated with mechanically deboned poultry meat-MDPM (turkey or chicken, frame or neck) treated in different ways before production (vacuum packed MDPM or air packed skeletons deboned at production) and stored frozen for 6 or 18 weeks have been studied using a full-factorial design and chemical, physical and sensory analysis. MDPM was obtained from a Beehive separator. Comminuted sausages with MDPM from turkey frames, stored at -25 °C as skeletons, packed in air for 18 weeks developed marked rancid odour and flavour which could also be detected by thiobarbituric acid reactive substances (TBARS) and the concentration of volatile compounds. Vacuum packed mechanically deboned meat irrespective of species and carcass part could be stored for up to 18 weeks and used in formulation of sausages without any serious changes in their sensory profiles. Instrumental colour differences between sausages were mainly due to species. Turkey sausages were darker, redder and less yellow than chicken sausages. Moisture and fat contents were influenced by carcass part and to a lesser extent depended on species and storage time. Principal least squares regression (PLS2) showed close relationships between instrumental parameters and sensory attributes. TBARS, hexanal and volatile compounds were highly correlated with rancid flavour while redness (a(∗)) was strongly related to sensory colour hue and colour strength.

2013-10-11

This study focused on the heterogeneity of consumer reactions, measured through poultry meat purchase intentions, when facing three cases of risk. The heterogeneity was analysed by latent class logistic regression that included all three risk cases. Approximately 60% of the respondents belonged to the group of production risk avoiders, in which the intention to purchase risk food was significantly lower than in the second group of risk neutrals. In addition to socio-demographic variables, the purchase intentions were statistically associated with several attitude-based variables. We highlighted some policy implications of the heterogeneity. Overall, the study demonstrated that risk matters to consumers, not all risk is equal, and consumer types react somewhat differently to different types of risk.

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.

Developing control points for halal slaughtering of poultry.

Science.gov (United States)

Shahdan, I A; Regenstein, J M; Shahabuddin, A S M; Rahman, M T

2016-07-01

Halal (permissible or lawful) poultry meat production must meet industry, economic, and production needs, and government health requirements without compromising the Islamic religious requirements derived from the Qur'an and the Hadiths (the actions and sayings of the Prophet Muhammad, peace and blessings be upon him). Halal certification authorities may vary in their interpretation of these teachings, which leads to differences in halal slaughter requirements. The current study proposes 6 control points (CP) for halal poultry meat production based on the most commonly used halal production systems. CP 1 describes what is allowed and prohibited, such as blood and animal manure, and feed ingredients for halal poultry meat production. CP 2 describes the requirements for humane handling during lairage. CP 3 describes different methods for immobilizing poultry, when immobilization is used, such as water bath stunning. CP 4 describes the importance of intention, details of the halal slaughter, and the equipment permitted. CP 5 and CP 6 describe the requirements after the neck cut has been made such as the time needed before the carcasses can enter the scalding tank, and the potential for meat adulteration with fecal residues and blood. It is important to note that the proposed halal CP program is presented as a starting point for any individual halal certifying body to improve its practices. © 2016 Poultry Science Association Inc.

Periodic surveys of the food supply for dioxins and dioxin-like compounds are a useful tool to measure changes in dioxin levels in the environment and to update predictions of human exposure to these toxic compounds from dietary components. In the mid-1990s, the US Department of Agriculture together with the US Environmental Protection Agency conducted a survey of dioxins in beef, pork, and poultry from slaughtering facilities across the US. A similar survey has been conducted to obtain statistically-valid information about current levels of dioxins in domesticallyproduced meat and poultry, to further investigate any unusual findings, and to compare these new results with those from the previous survey.

Cancer prevention guidelines recommend limiting intake of red meat and avoiding processed meat; however, few studies have been conducted on the effects of specific red meat subtypes on colon cancer or rectal cancer risk. The study aim was to evaluate associations between intake of red meat and its subtypes, processed meat, fish, and poultry and risk for colon cancer or rectal cancer in the Danish Diet, Cancer and Health cohort study. We also evaluated whether fish or poultry should replace red meat intake to prevent colon cancer or rectal cancer. During follow-up (13.4 y), 644 cases of colon cancer and 345 cases of rectal cancer occurred among 53,988 participants. Cox proportional hazards models were used to compute incidence rate ratio (IRRs) and 95% CIs. No associations were found between intake of red meat, processed meat, fish, or poultry and risk for colon cancer or rectal cancer. The risk associated with specific red meat subtypes depended on the animal of origin and cancer subsite; thus, the risk for colon cancer was significantly elevated for higher intake of lamb [IRR(per 5g/d) = 1.07 (95% CI: 1.02-1.13)], whereas the risk for rectal cancer was elevated for higher intake of pork [IRR(per 25g/d) = 1.18 (95% CI: 1.02-1.36)]. Substitution of fish for red meat was associated with a significantly lower risk for colon cancer [IRR(per 25g/d) = 0.89 (95% CI: 0.80-0.99)] but not rectal cancer. Substitution of poultry for red meat did not reduce either risk. This study suggests that the risks for colon cancer and potentially for rectal cancer differ according to the specific red meat subtype consumed.

Full Text Available Poultry farming is a strategic branch of the livestock sector with high potential recovery in a short period of time. Today poultry farming in our country is developed in three basic systems: industrial-intensive, household-intensive and household-extensive, more importance and priority being given to intensive-industry system, the share of which in the production of eggs and meat consumption, is 50-60% of the total volume of poultry production. Intensive-industrial system is characteristic of poultry factories using biological material with valuable productive potential, are equipped with modern technological equipment, which ensures increasing the rate of production and delivery of eggs and meat, poultry achieve high production, reducing costs per unit production. In this system annually will produce 25-30 thousand tons of meat, 280-350 million eggs for consumption, including 100-150 million eggs for export. The household-intensive system is specific for small and medium farms is characteristic of which optimal dimension is considered of 1-10 thousand laying hens or up to 20-40 thousand chickens bred for meat. Household-extensive system is specific for individual poultry farms; the production obtained was mainly used to ensure family needs.

Full Text Available Many people have led to the consumption of organic animal products in the event that the increase in sensitivity to a healthy diet in developed countries, and maintaining the safety of food of animal origin. Feeding and breeding in conventional production are emerged some of the negative effects and also it is more in organic production with new restrictions. Organic production is based on animal welfare. On the basis of behaviors such as feather-pecking and cannibalism known to be low in protein level of rations and unbalanced in terms of amino acids or minerals. As of 2015, organic poultry feed provided the appropriate conditions that will be 95% organic certified in Turkey and therefore, to create a balanced ration and feed hygiene in protecting brings serious challenges. Fodder supply of organic poultry feed raw materials that make up the quality, quantity and issue forms a significant effect on the health of the poultry additives permitted. The quality of the feed raw materials that constituent diets, quantity, feed supplying form and permitted feed additives significantly affects the health of poultry. Different physiological stages of the animal's nutritional requirements in order to ensure production of quality poultry products must be met from organically produced and very well-known with the contents of feedstuff digestibility. In this study, the problems encountered in feeding can be eliminated while performing economic production with considering animal welfare, following that balanced and adequate organic ration formulations and issues such as improving the production of feed raw materials are discussed.

Fresh poultry meat and poultry products are highly perishable foods and high potential sources of human infection due to the presence of several foodborne pathogens. Focusing on the microbial control of poultry products, the food industry generally implements numerous preventive measures based on the Hazard Analysis and Critical Control Points (HACCP) food safety management system certification together with technological steps, such as refrigeration coupled to modified atmosphere packaging that are able to control identified potential microbial hazards during food processing. However, in recent years, to meet the demand of consumers for minimally processed, high-quality, and additive-free foods, technologies are emerging associated with nonthermal microbial inactivation, such as high hydrostatic pressure, irradiation, and natural alternatives, such as biopreservation or the incorporation of natural preservatives in packaging materials. These technologies are discussed throughout this article, emphasizing their pros and cons regarding the control of poultry microbiota and their effects on poultry sensory properties. The discussion for each of the preservation techniques mentioned will be provided with as much detail as the data and studies provided in the literature for poultry meat and products allow. These new approaches, on their own, have proved to be effective against a wide range of microorganisms in poultry meat. However, since some of these emergent technologies still do not have full consumer's acceptability and, taking into consideration the hurdle technology concept for poultry processing, it is suggested that they will be used as combined treatments or, more frequently, in combination with modified atmosphere packaging.

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

2018-01-01

Full Text Available Injuries of repetitive efforts constitute one of the prime causes of absenteeism in the workplace, bear a considerable cost for the public health system and can cast doubt on the sustainability of a company. The objective of this paper is to build, in the researchers, the needed knowledge to choose a set of relevant scientific articles about repetitive strain injuries in the poultry meat industry, aiming to identify characteristics in those scientific publications that have the potential to contribute to the topic of this paper. The research is characterized as exploratory-descriptive, and draws on primary and secondary data sources. The study involves the application of a method for the selection and analysis of the selected articles. To this end, the method utilized was the knowledge development process—constructivist (Proknow-C, as the theoretical intervention instrument. Within the process development, a portfolio of 16 articles aligned to the research and scientifically recognized with the main periodicals, papers, authors and keywords was obtained. The ProKnow-C process allowed us to identify opportunities in the literature about injuries in the poultry meat industry and showed opportunities for future research. This paper, under the constructivist perspective, presents a structured process to build, in the researcher, the necessary knowledge for the identification, selection and analysis of relevant scientific articles relating to research context and, for these articles, find prominences and opportunities for a research theme without similar publications.

The condition of the poultry industry in Poland

Directory of Open Access Journals (Sweden)

Iwona Kozioł

2014-08-01

Full Text Available The poultry industry in Poland is characterized by high dynamics of development and in this regard was placed at the forefront of European Union countries. The main reason for the acceleration and modernization of the industry was the Polish accession to the European Union. Sanitary and veterinary requirements, and rules on the placing of poultry products in the trade, which our country was obliged to fulfill, led to the sector producing products with a high level of security. Rapidly growing domestic demand and foreign markets for Polish products affectes the growth of poultry production. Consumers are attracted primarily by the high quality products and reasonable price, as well as the relatively low cost of production. The industry has become an example of what can grow even in a crisis. As a result of changes occurring in the Polish market, meat and aspecially poultry meat is becoming increasingly important, becoming an essential part of the economy. Forecasts for the poultry industry in 2014 are positive, sae to an anticipated decline in grain prices and a limited supply of pork and beef. This will increase the global and the European Union demand for white meat, due to its nutritional properties and competitive prices.

Occurrence of bioactive sphingolipids in meat and fish products

DEFF Research Database (Denmark)

Hellgren, Lars

2001-01-01

/neutral glycolipids varied from 1 to 2.9, while in poultry this ratio varied between 5.2 to 19.2 and in red meat it varied from 1.6 to 8.3. The fatty acid composition of sphingomyelin in fish was dominated by C24:1 (Delta (9)) or C22:1 (Delta (9)), while C16:0 and C18:0 were the dominating sphingomyelin species....... Therefore we investigated the contents of sphingomyelin and neutral glycosphingolipids in commonly consumed meat and fish products. Sphingomyelin and glycosphingolipids were found in all foodstuffs studied. The total amount varied between 118 +/- 17 nmol/g (cod) to 589 +/- 39 nmol/g (chicken leg). Generally......, lower amounts of sphingolipids were determined in fish meat than in red meat and poultry, while poultry was the richest source of this class of lipids. However, fish meat contained a relatively high content of neutral glycolipids compared with other types of meat. Thus, in fish the ratio sphingomyelin...

The specific objectives of the programme have been to evaluate the magnitude, fate and significance of agricultural chemical residues in edible tissues and by-products of livestock and poultry, aided by radiotracer techniques. It was anticipated that the data arising from studies conducted under this programme would be useful in assessing the toxicological significance of studied chemicals to exposed animals and to humans who may consume potentially polluted meat, milk or eggs. A separate abstract was prepared for each of the 13 papers in this report

Red meat and poultry intakes and risk of total and cause-specific mortality: results from cohort studies of Chinese adults in Shanghai.

Directory of Open Access Journals (Sweden)

Yumie Takata

Full Text Available Most previous studies of meat intake and total or cause-specific mortality were conducted in North America, whereas studies in other areas have been limited and reported inconsistent results. This study investigated the association of red meat or poultry intake with risk of total and cause-specific mortality, including cancer and cardiovascular disease (CVD, in two large population-based prospective cohort studies of 134,290 Chinese adult women and men in Shanghai. Meat intakes were assessed through validated food frequency questionnaires administered in person at baseline. Vital status and dates and causes of deaths were ascertained through annual linkage to the Shanghai Vital Statistics Registry and Shanghai Cancer Registry databases and home visits every 2-3 years. Cox regression was used to calculate hazard ratios (HRs and 95% confidence intervals (CIs for the risk of death associated with quintiles of meat intake. During 803,265 person-years of follow up for women and 334,281 person-years of follow up for men, a total of 4,210 deaths in women and 2,733 deaths in men accrued. The median intakes of red meat were 43 g/day among women and 54 g/day among men, and pork constituted at least 95% of total meat intake for both women and men. Red meat intake was associated with increased total mortality among men, but not among women; the HR (95% CI comparing the highest with the lowest quintiles were 1.18 (1.02-1.35 and 0.92 (0.82-1.03, respectively. This sex difference was statistically significant (P = 0.01. Red meat intake was associated with increased risk of ischemic heart disease mortality (HR = 1.41, 95% CI = 1.05-1.89 and with decreased risk of hemorrhagic stroke mortality (HR = 0.62, 95% CI = 0.45-0.87. There were suggestive inverse associations of poultry intake with risk of total and all-CVD mortality among men, but not among women. Further investigations are needed to elucidate the sex-specific associations between red

Though imports of products of animal origin into the European Union (EU) have to comply with legal requirements and quality standards of the community, food consignment rejections at external EU borders have been increasing in recent years. This study explored microbiological metrics according to national target and critical values valid for samples at consumer level of 498 fresh poultry meat and 136 fresh pork filets from consignments subjected to physical checks during clearing at the border inspection post Hamburg harbour between January 2014 and December 2015 with ISO standard methods. Quantitative results indicated that critical thresholds for aerobic counts, Enterobacteriaceae, and E. coli were never surpassed. Merely for staphylococci, one poultry sample (0.2%) and 10 pork samples (9.3%) exceeded the critical limit (3.7 log cfu/g). However, qualitative analyses revealed that, Staphylococcus aureus was present in 16% and 10% of all poultry and pork samples, respectively, though no methicillin-resistant Staphylococcus aureus could be confirmed. Moreover, E. coli was present in 50% and 67% of all pork and poultry samples, respectively, and thereof 33 isolates were confirmed as extended-spectrum β-lactamase-producing E. coli. Only 1.2% of the poultry samples were unacceptable due to the presence of Salmonella spp., whereas they were not detected in any pork sample. Campylobacter spp. were not detected in any sample. Though imported pork and poultry meat complies mostly with national market requirements, it might pose a potential risk to public health, especially for a direct or indirect foodborne transmission of imported, uncommon strains of zoonotic bacteria.

Meat and meat products – analysis of the most common threats in the years 2011-2015 in Rapid Alert System for Food and Feed (RASFF)

Science.gov (United States)

Kononiuk, Anna D.; Karwowska, Małgorzata

The key tool used in the European Union in order to eliminate the risks associated with the consumption of potentially hazardous food is RASFF - Rapid Alert System for Food and Feed Safety. The RASFF was established to increase accountability and strengthening cooperation between states of the European Union in the field of food safety control. The aim of this study was to explore the trends and temporal and spatial distribution of notifications on food safety hazards between January 2011 and December 2015 with a special emphasis on meat and meat products on the basis of notification from RASFF. The study analyzed notifications on the annual reports of the RASFF published by the European Commission and requests added to the portal RASFF in the period 01.01.2011 - 31.12.2015 on the category of “meat and meat products (other than poultry) and “poultry meat and poultry meat products”. Analysis included detailed information on each notification, such as the classification and date, hazard category, notifying country, country origin. The most common classifications of notification were ‘alert’ and ‘border rejection’. Generally, basis of this notifications were ‘company’s own check’ and ‘official control on the market’. Pathogenic microorganisms were the most often hazard of category in which the higher number of notifications concerned with Salmonella spp. Alert notification which is the most dangerous for consumers were the most common type of classification for notifications on ‘meat and meat product’ category. The most of notifications in category ‘poultry meat and poultry meat products’ were the result of border control. Pathogenic microorganisms were the reason for the huge number of notifications in studied product categories. Many of notifications were associated with products which origin countries were outside RASFF member states.

Osman İrfan İLHAK

2015-01-01

Full Text Available The identification of meat species used in meat products is important by reason of economic considerations, religious factors, verification of label, and prevention of unfair-market competition. In this paper, multiplex PCR method was experienced for routine detection of equine (horse and donkey, poultry (chicken and turkey, pig and cattle meat in sucuk (sausage. The primers used for these animals generated specific fragments, and they did not show cross reactions with the DNA from the other genus of animal. After multiplex PCR was successfully optimized, a field study was carried out to investigate the presence of horse, donkey, chicken, turkey and pig meat in 50 sucuks (30 beef and 20 beef + poultry collected from markets. The result of the field study indicated that 23.3% of 30 beef sucuk samples were containing poultry meat. None of the 50 sucuk samples was containing pig meat, but one (2% of the samples generated equine fragment. The present study showed that the multiplex PCR method can be used for routine analysis of meat species identification, verification and control of label information of meat products.

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.

2000-12-05

A study was undertaken to determine populations and profiles of yeast species on fresh and processed poultry products upon purchase from retail supermarkets and after storage at 5 degrees C until shelf life expiration, and to assess the potential role of these yeasts in product spoilage. Fifty samples representing 15 commercial raw, marinated, smoked, or roasted chicken and turkey products were analyzed. Yeast populations were determined by plating on dichloran rose bengal chloramphenicol (DRBC) agar and tryptone glucose yeast extract (TGY) agar. Proteolytic activity was determined using caseinate and gelatin agars and lipolytic activity was determined on plate count agar supplemented with tributyrin. Populations of aerobic microorganisms were also determined. Initial populations of yeasts (log10 cfu/g) ranged from less than 1 (detection limit) to 2.89, and increased by the expiration date to 0.37-5.06, indicating the presence of psychrotrophic species. Highest initial populations were detected in raw chicken breast, wings, and ground chicken, as well as in turkey necks and legs, whereas roasted chicken and turkey products contained less than 1 log10 cfu/g. During storage, yeast populations increased significantly (P chicken, ground chicken, liver, heart and gizzard, and in ground turkey and turkey sausage. Isolates (152 strains) of yeasts from poultry products consisted of 12 species. Yarrowia lipolytica and Candida zeylanoides were predominant, making up 39 and 26% of the isolates, respectively. Six different species of basidiomycetous yeasts representing 24% of the isolates were identified. Most Y. lipolytica strains showed strong proteolytic and lipolytic activities, whereas C. zeylanoides was weakly lipolytic. Results suggest that yeasts, particularly Y. lipolytica, may play a more prominent role than previously recognized in the spoilage of fresh and processed poultry stored at 5 degrees C.

New scientific challenges - the possibilities of using selenium in poultry nutrition and impact on meat quality

Science.gov (United States)

Marković, R.; Glišić, M.; Bošković, M.; Baltić, M. Ž.

2017-09-01

Physiological stress is one of many concerns facing modern broiler production. In conditions when birds are exposed to stress, supplementation of selenium, which is a crucial glutathione peroxidase enzymatic cofactor, increases the antioxidant capacity of the animals and decreases the harmful effects of free radicals. Dietary selenium improves production performance and health of animals, and positively affects the immune system, the quality, selenium content and fatty acid composition of meat and eggs. There are several different forms of selenium, the most common dietary supplements being an inorganic form (sodium selenite) and anorganic form (selenomethionine). However, in recent years, new forms of selenium, such as a 2-hydroxy-4-methylselenobutanoic acid (HMSeBA) and nanoselenium, which have more bioavailability, bioefficacy, and low toxicity have been designed. In this short comparative overview discusses the effects of inorganic, organic and nanoforms of selenium on production results, glutathione peroxidase activity, meat quality and level of toxicity in poultry.

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.

Extensive protein hydrolyzation is indispensable to prevent IgE-mediated poultry allergen recognition in dogs and cats.

Science.gov (United States)

Olivry, Thierry; Bexley, Jennifer; Mougeot, Isabelle

2017-08-17

The central premise for the commercialization of diets with hydrolyzed ingredients is that the small-sized digested peptides would be unable to crosslink allergen-specific IgE at the surface of tissue mast cells and induce their degranulation. Evidence for the validity of this concept to diagnose food allergies in dogs and cats is limited, however. Our objectives were to study the recognition of standard and variably hydrolyzed poultry extracts by sera from dogs and cats with elevated chicken-specific serum IgE. Forty sera from dogs and 40 from cats with undetectable, low, medium or high serum levels of chicken-specific IgE were tested by ELISA on plates coated with the positive controls chicken, duck and turkey meat extracts and the negative controls beef meat (dogs) or wheat (cats). Plates were also coated with a non-hydrolyzed chicken meal, and mildly- or extensively-hydrolyzed poultry feather extracts. The frequencies of dogs with positive IgE against the various extracts were: chicken meat: 100%, duck and turkey meats: 97%, beef meat: 3%, non-hydrolyzed chicken meal: 73%, mildly-hydrolyzed poultry feathers: 37% and extensively-hydrolyzed poultry feathers: 0%. For cats, these respective percentages were (with wheat replacing beef as a negative control): 100, 84, 97, 7, 7, 0 and 0%. To detect any allergenic cross-reactivity between poultry meat-based and feather hydrolysate-derived extracts, an IgE ELISA inhibition was also done. Ten canine sera with the highest level of anti-poultry IgE in the previous experiment were incubated overnight with a previously optimized 50 μg amount of each of the extracts used above. We performed ELISA on plates coated with chicken, duck or turkey meats with or without inhibitors. The median inhibition percentages after incubation with the non-hydrolyzed chicken meal were ~22%, with the mildly-hydrolyzed poultry feathers: 14-22%, and those with the extensively-hydrolyzed poultry feathers: 5 to 10%; the last inhibition level was

Family poultry production in Mauritius: problems and prospects

International Nuclear Information System (INIS)

Jugessur, V.S.; Seenevassen Pillay, M.M.

2002-01-01

The Republic of Mauritius has been self-sufficient in poultry meat and eggs for more than two decades and has been successfully meeting the increasing demand for these commodities. About 85% of the poultry meat is presently produced by four industrial farms, 10% by small commercial producers, and around 5% by family (backyard) poultry farms. The flourishing broiler production industry has transformed the erstwhile important traditional backyard poultry farming of indigenous chickens into an insignificant side activity on the main island of Mauritius, while on the other hand, scavenging chickens continue to be an important source of both food and income on Rodrigues, the second biggest island territory of the Republic. A survey carried out on 30 selected family poultry farms in Mauritius and Rodrigues in 1999 and 2000 enabled the identification of the major problems faced by smallholder poultry farmers. At the same time the results provided a basis for future interventions for improving family poultry production. The results showed that diseases like fowl pox, Newcastle disease, Gumboro disease, respiratory and parasitic diseases occurred all year round on 42% and 82% of farms in Mauritius and Rodrigues, respectively. Low to mild helminth and lice infestations were detected on 40% and 50% of the farms in Mauritius and Rodrigues, respectively. (author)

Sui, Zhixian; Raubenheimer, David; Rangan, Anna

2017-08-01

The study of meal patterns and overall diet in relation to health outcomes may be more important than focusing on single nutrients or food groups. The present study aimed to explore the composition of main meals and snacks in the Australian population and examine associations between meat/poultry/fish and other foods. The study utilised 24 h recalls. Meal composition was defined based on average intakes of food groups per meal disaggregated from all food sources. 2011-12 National Nutrition and Physical Activity Survey. Australian people (n12153) aged 2 years or above. Overall, breakfast was the smallest meal of the day, typically consisting of grains, dairy products and fruit. Lunch was the second largest meal, consisting mostly of grains, non-starchy vegetables and meat/poultry/fish. The largest meal was dinner, comprising meat/poultry/fish, vegetables (starchy and non-starchy), grains and often including discretionary beverages (children) or alcohol (adults). The main food groups consumed at snacking occasions were dairy, fruit, discretionary foods and beverages (including alcohol for adults). The most frequently consumed meat types were beef and chicken at dinner and ham at lunch. Non-starchy vegetables were accompanying foods for red meat, poultry and fish/seafood consumed in varying portion sizes, but did not accompany processed meat. The present study considered meat, poultry and fish as the meal centre and their accompaniments of other food groups at different eating occasions. These findings expand the background evidence for health professionals developing meal-based framework/guidelines and public health messages.

The Study of Effect of Surimi Production Steps on Chemical Composition and Electrophoresis Pattern of Myofibrillar Proteins of Mechanically Deboned poultry meat (MDPM

Directory of Open Access Journals (Sweden)

Sh Haji BagherNaeeni

2013-08-01

Full Text Available Mechanically deboning poultry meat (MDPM is widely used due to its suitable technological properties as well as low lipids and saturated fatty acids contents. Besides, production processes applied during the surimi production can improve the technological properties of MDPM. That is to say, the production steps of surimi can change chemical composition and concentration of myofibrillar proteins and improve functional properties of MDPM. In this study, MDPM was prepared from the poultry meat. The production process consisted of 2 washing steps with sodium bicarbonate solution followed by another washing step with 4°C water. Afterwards, chemical properties of MDPM and surimi (moisture content, protein, lipid, and ash content as well as electrophoresis pattern were evaluated. Result showed that surimi production steps could significantly decrease protein, lipid and ash contents; however, moisture content of MDPM increased significantly. The result of electrophoresis indicated a significant increase in heavy chain myosin with 200 KDa and actin with 45 KDa molecular weights. It was concluded that the production steps improved the chemical properties and increased the concentration of MDPM myofibrillar proteins.

Effect of organic poultry purchase frequency on consumer attitudes toward organic poultry meat.

Science.gov (United States)

Van Loo, Ellen; Caputo, Vincenzina; Nayga, Rodolfo M; Meullenet, Jean-Francois; Crandall, Philip G; Ricke, Steven C

2010-09-01

Because of the growing consumers' interest in organic meat, consumers' (N = 976) attitude toward organic meat was evaluated. Most respondents (59%) occasionally purchased organic chicken. To determine the organic chicken consumer profile, the organic chicken consumption frequencies of different demographic groups were compared. The results show dependence on age (P= 0.039) and ethnicity (P = 0.015). Older respondents as well as respondents who identified themselves as Caucasians tended to buy organic chicken more frequently. However, many other socio-demographic factors were not correlated with organic chicken consumption: gender (P = 0.185), education (P = 0.235), household income (0.867), living with partner or not (P = 0.235), and number of children (P = 0.883). Taste was identified as the most important meat quality attribute (perceived as [very] important by 94% of the respondents). Other important meat quality criteria were: general appearance, overall health, price, nutritional value, and containing no medical residues. "Organically produced" appeared to not be that important compared with other criteria. When respondents bought organic chicken more often, the importance of most of the meat quality attributes shifted to higher levels of importance, except for the price where an adverse effect was shown. The main motivation factors to buy organic chicken were the perception that organic chicken has fewer residues (pesticides, hormones, antibiotics), is safer, and healthier. The high price for organic meats was the strongest limiting factor for organic meat purchases followed by poor availability. Approximately 41% of the non-buyers and 30% of the occasional buyers perceived organic meat as not or hardly likely to be available in their supermarket. This study obtained a better knowledge of consumers' attitudes and perception of organic chicken as well as the effect of various demographics on the likelihood of buying organic chicken.

Radiation preservation of meat and meat products: A review.

Science.gov (United States)

Dempster, J F

1985-01-01

The World Health Organisation (WHO) in 1980 clarified the position regarding the medical acceptability of irradiated foods when it said'…no health hazard results from consuming any food irradiated up to a dose of one megarad (1 Mrad)'. This resulted in renewed interest in irradiation as a cost-effective alternative to traditional preservation methods such as canning and freezing. Thus, radurisation (the application of ionising radiation at a dose level which substantially reduces the microbial population) increases the shelf life of poultry, comminuted meat and meat dishes significantly. Low dose irradiation, or radicidation, eliminates parasites such as Trichinae and cysticerci in pork and, very importantly, salmonella organisms in poultry and red meat. Therefore, irradiation has an important rôle to play in public health protection. High dose irradiation, or radappertisation ('cold sterilisation'), uses doses in excess of 1 Mrad and is analogous to retorting as understood in the canning industry. However, it can adversely affect quality in producing 'free radicals' in high protein foods such as meat. To prevent this, special precautions are necessary, e.g. irradiation is conducted at very low temperatures and the product is usually vacuum packed. A further potential use of irradiation is its ability to reduce the quantity of nitrite necessary in cured meats. This may become of practical significance if legislation further reduces the amount of nitrite permitted in these products. Copyright © 1985. Published by Elsevier Ltd.

Mycotoxins in poultry production

Directory of Open Access Journals (Sweden)

Resanović Radmila M.

2009-01-01

Full Text Available All poultry is sensitive to mycotoxins. This partly depends on the type, age and production categories of poultry, their living conditions and nutritive status and partly on the type, quantity and duration of mycotoxin ingestion. The presence of mycotoxins results in significant health disorders and a decrease in production performances. This leads to considerable economic loss for the poultry industry - either direct losses, i.e. death of the poultry or the indirect ones, i.e. the decrease in body mass, number and quality of eggs, greater food conversion, and immunosuppression. Immunosuppression results in increased sensitivity to infective agents and a bad vaccinal response. Morevover, mycotoxin residues in poultry meat, eggs and products derived from them pose a threat to human health. In order to prevent and reduce the negative implications of mycotoxins in the poultry production, it is necessary to create both global and national strategies for combatting mycotoxins, advance diagnostic techniques and procedures, intensify the control of food quality, introduce new limits on the maximum amount of mycotoxins allowed in food and poultry feed used for certain species and categories of animals, and synchronise it with the European standards.

Heterocyclic amines in meat and meat products

Directory of Open Access Journals (Sweden)

Aliye BULGAN

2013-06-01

Full Text Available Heterocyclic amines (HA are the mutagenic/carcinogenic compounds which generate as a result of cooking of red meat, poultry meat and fish fillets at high temperatures. Up to 20 different HAs were detected and classified in the researches that conducted on these types of meats cooked at high temperatures. HAs are the products of Maillard reactions and the Strecker degredation of main precursors such as creatine/creatinine, aminoacid and the polysaccharides. Many physical and chemical factors effect the formation of HAs. Thus, it was reported by many researchers that utilizing coating and marination processes in addition to using natural and synthetic antioxidants and seasonings-plant extracts were effective on inhibiting/decreasing the formation of HAs. Additionally, boiling/steaming and microwave cooking methodologies were recommended instead of barbecuing, grilling or frying to inhibit/decrease the formation of HAs. The HAs formed in meat and meat products and the factors which have effects on the formation of HAs are presented in this review.

Antimicrobial use in Chinese swine and broiler poultry production.

Science.gov (United States)

Krishnasamy, Vikram; Otte, Joachim; Silbergeld, Ellen

2015-01-01

Antimicrobial use for growth promotion in food animal production is now widespread. A major concern is the rise of antimicrobial resistance and the subsequent impact on human health. The antimicrobials of concern are used in concentrated animal feeding operations (CAFOs) which are responsible for almost all meat production including swine and poultry in the US. With global meat consumption rising, the CAFO model has been adopted elsewhere to meet this demand. One such country where this has occurred is China, and evidence suggests 70% of poultry production now occurs outside of traditional small farms. Moreover, China is now the largest aggregate consumer of meat products in the world. With this rapid rise in consumption, the Chinese production model has changed along with the use of antimicrobials in feeds. However, the specific antibiotic use in the Chinese food animal production sector is unclear. Additionally, we are aware of high quantities of antimicrobial use because of reports of high concentrations of antimicrobials in animal waste and surface waters surrounding animal feeding operations. In this report, we estimate the volume of antibiotics used for swine and poultry production as these are the two meat sources with the highest levels of production and consumption in China. We adopt a model developed by Mellon et al. in the US for estimating drug use in feed for poultry and swine production to estimate overall antimicrobial use as well as antimicrobial use by class. We calculate that 38.5 million kg [84.9 million lbs] were used in 2012 in China's production of swine and poultry. By antibiotic class, the highest weights are tetracyclines in swine and coccidiostats in poultry. The volume of antimicrobial use is alarming. Although there are limitations to these data, we hope our report will stimulate further analysis and a sense of urgency in assessing the consequences of such high levels of utilization in terms of antibiotic resistance in the food supply

Can we improve the nutritional quality of meat?

Science.gov (United States)

Scollan, Nigel D; Price, Eleri M; Morgan, Sarah A; Huws, Sharon A; Shingfield, Kevin J

2017-11-01

The nutritional value of meat is an increasingly important factor influencing consumer preferences for poultry, red meat and processed meat products. Intramuscular fat content and composition, in addition to high quality protein, trace minerals and vitamins are important determinants of nutritional value. Fat content of meat at retail has decreased substantially over the past 40 years through advances in animal genetics, nutrition and management and changes in processing techniques. Evidence of the association between diet and the incidence of human non-communicable diseases has driven an interest in developing production systems for lowering total SFA and trans fatty acid (TFA) content and enrichment of n-3 PUFA concentrations in meat and meat products. Typically, poultry and pork has a lower fat content, containing higher PUFA and lower TFA concentrations than lamb or beef. Animal genetics, nutrition and maturity, coupled with their rumen microbiome, are the main factors influencing tissue lipid content and relative proportions of SFA, MUFA and PUFA. Altering the fatty acid (FA) profile of lamb and beef is determined to a large extent by extensive plant and microbial lipolysis and subsequent microbial biohydrogenation of dietary lipid in the rumen, and one of the major reasons explaining the differences in lipid composition of meat from monogastrics and ruminants. Nutritional strategies can be used to align the fat content and FA composition of poultry, pork, lamb and beef with Public Health Guidelines for lowering the social and economic burden of chronic disease.

Effects of microbial aerosol in poultry house on meat ducks’ immune function

Directory of Open Access Journals (Sweden)

Guanliu YU

2016-08-01

Full Text Available The aim of this study was to evaluate effects of microbial aerosols on immune function of ducks and shed light on the establishment of microbial aerosol concentration standards for poultry. A total of 1800 1-d-old Cherry Valley ducks were randomly divided into 5 groups (A, B, C, D and E with 360 ducks in each. To obtain objective data, each group had three replications. Concentrations of airborne bacteria, fungi, endotoxin in different groups were created by controlling ventilation and bedding cleaning frequency. Group A was the control group and hygienic conditions deteriorated progressively from group B to E. A 6-stage Andersen impactor was used to detect the aerosol concentration of aerobes, gram-negative bacteria, fungi and AGI-30 microbial air sampler detect the endotoxin, and Composite Gas Detector detect the noxious gas. In order to assess the immune function of meat ducks, immune indicators including H5 AIV antibody titer, IgG, IL-2, T-lymphocyte transformation rate, lysozyme and immune organ indexes were evaluated. Correlation coefficients were also calculated to evaluate the relationships among airborne bacteria, fungi, endotoxin and immune indicators. The results showed that the concentration of airborne aerobe, gram-negative bacteria, fungi, endotoxin have a strong correlation to H5 AIV antibody titer, IgG, IL-2, T-lymphocyte transformation rate, lysozyme and immune organ indexes, respectively. In addition, when the concentration of microbial aerosol reach the level of group D, serum IgG (6 - 8 weeks, lysozyme (4 week were significantly higher than in group A (P < 0.05; serum IL-2 (7 and 8 weeks , T-lymphocyte transformation rate, lysozyme (7 and 8 weeks, spleen index (6 and 8 weeks and bursa index (8 week were significantly lower than in group A(P < 0.05 or P < 0.01. The results indicated that a high level of microbial aerosol adversely affected the immune level of meat ducks. The microbial aerosol values in group D provide a basis

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.

Incidence of Salmonella Infantis in poultry meat and products and the resistance of isolates to antimicrobials

Science.gov (United States)

Kalaba, V.; Golić, B.; Sladojević, Ž.; Kalaba, D.

2017-09-01

Globalisation, climate change, changes in eating habits and the food industry, modern animal husbandry and market demands often have a negative impact on quality assurance, food safety and animal health. After the eradication of some zoonotic diseases that previously often jeopardized the human population, today in developed countries, the focus is mainly on the control of zoonoses transmitted by food. Salmonella is one of the most common pathogens that can be transmitted from animals to humans, and its reservoirs are poultry, cattle and pigs, so one transmission route to humans is from contaminated food of animal origin. Multidrug-resistant isolates of Salmonella, which can transfer their resistance genes to other microorganisms, are considered a serious threat to public health. Control of Salmonella primarily depends on a good monitoring system and knowledge of the presence of serovars and strains in an epizootiological area. During the first nine months of 2016, 1321 samples of poultry meat and products were examined, among which 108 harboured Salmonella. Altogether, 29 of the 108 isolates (26.85%) were Salmonella Infantis. For all 29 S. Infantis isolates, antimicrobial resistance was tested by the disc diffusion method. The isolates showed 100% resistance to amoxicillin, and nalidixic acid.

2016-01-01

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

International Nuclear Information System (INIS)

Manzoor, T.; Ayub, M.; Ashraf, M.; Manzoor, M.; Tabinda, A.B.

2005-01-01

Consumption of chicken meat has tremendously increased, especially in big cities of Pakistan like Lahore, during last few decades, due to low cholesterol level and lesser price as compared to beef and lamb meat. Non- scientific slaughter methods common in practice have increased the risk of bacterial load on chicken meat making it unsafe for human consumption. Keeping in view, the risk of bacterial contamination on chicken meat present study was conducted to determine bacterial load in different areas (Shad Bagh, Samanabad, Sanda) of city Lahore. Pour-plate method was used with differential media of blood agar, and selective medias of eosinmethylene blue, citrimide agar and mannitol agar. Maximum bacteria] growth (35.3 plus minus 0.77 million per gram) was observed in blood agar in Shad Bagh's poultry meat while in Samanabad's poultry meat maximum bacterial growth was observed in eosinmethylene blue agar (9.6 plus minus 0.40 million per gram) while Sanda's poultry meat showed maximum bacterial growth in cetrimide agar (6.9 plus minus 0.43).

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.

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.

McMillin, Kenneth W

2017-10-01

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.

2015-06-01

Avian hosts constitute a natural reservoir for thermophilic Campylobacter species, primarily Campylobacter jejuni and Campylobacter coli, and poultry flocks are frequently colonized in the intestinal tract with high numbers of the organisms. Prevalence rates in poultry, especially in slaughter-age broiler flocks, could reach as high as 100% on some farms. Despite the extensive colonization, Campylobacter is essentially a commensal in birds, although limited evidence has implicated the organism as a poultry pathogen. Although Campylobacter is insignificant for poultry health, it is a leading cause of food-borne gastroenteritis in humans worldwide, and contaminated poultry meat is recognized as the main source for human exposure. Therefore, considerable research efforts have been devoted to the development of interventions to diminish Campylobacter contamination in poultry, with the intention to reduce the burden of food-borne illnesses. During the past decade, significant advance has been made in understanding Campylobacter in poultry. This review summarizes the current knowledge with an emphasis on ecology, antibiotic resistance, and potential pre- and postharvest interventions.

2005-01-15

A total of 253 samples of raw meat (bovine, swine and poultry) were collected in local supermarkets in Sao Paulo, Brazil, and analysed for Salmonella and E. coli 0157:H7, in order to determine their microbiological quality and compliance with the established standards for these two bacteria. Additionally, samples of ground beef were artificially contaminated with S. enteritidis and E. coli 0157:H7, in order to determine the effect of refrigeration and freezing temperature during the storage period (4ºC for 5 days, and - 18ºC for 90 days, respectively). Twenty-three samples (9.1%) were positive to Salmonella and seven different serotypes were isolated, S. enteritidis being the most common serotype founded (34,8%). The results of the artificially contaminated samples showed that E. coli 0157:H7 was sensitive to refrigeration as well as freezing temperature. S. enteritidis was only affected by freezing temperature during the storage time. (author)

This study investigated the effects of acute heat stress and slaughter processing on poultry meat quality and carbohydrate metabolism. Broilers (200) were randomly divided into 2 groups receiving heat stress (HS; 36°C for one h), compared to a non-stressed control (C). At slaughter, each group was further divided into 2 groups for slaughter processing (L = laboratory; F = commercial factory). L group breasts were removed immediately after bleeding without carcass scalding or defeathering, and stored at 4°C. F group broilers were scalded (60°C, 45 s) after bleeding and defeathering. Then the breasts were removed and cooled in ice water until the core temperature was ≤4°C. Rates of Pectoralis core temperature and pH decline were changed by slaughter processing, but only HS affected ultimate pH in group L. HS muscles had higher L* values (P  0.05). Sarcoplasmic protein solubility was higher in F processed birds (P < 0.05). HS decreased the solubility of myofibrillar and total protein in the L-slaughtered birds. Thus, HS caused a higher frequency of accelerated muscle glycolysis than controls. Factory processing (chilling) could not completely eliminate the effects of accelerated glycolysis caused by pre-slaughter HS. © 2016 Poultry Science Association Inc.

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.

Biological conversion of poultry and animal waste to a feedstuff for poultry

Energy Technology Data Exchange (ETDEWEB)

El Boushy, A.R.; Klaassen, G.J.; Ketelaars, E.H.

1985-06-01

Poultry and animal waste can be converted into a high protein feed-stuff by biological digestion and degradation, oxidation or by the action of micro-organisms and algae. These processes might help to solve the accummulating problem of disposal of poultry and animal waste, which in some cases are not suitable as soil fertilizers and cause pollution problems. International co-operation between advanced industrialized countries and developing areas is not only desirable but essential to overcome malnutrition by increasing the animal protein supply in the form of meat and eggs. Only a limited number of published data are available but nevertheless five types of treated waste are considered useful under certain conditions as feedstuffs for poultry: 1. housefly pupae meal - caged layer manure degraded by housefly larvae; 2. earthworm meal - another biodegradation of caged layer manure; 3. liquor and residue from a ditch used for oxidizing swine liquid manure; 4. aerobic fermentation of poultry manure; and 5. meals produced from algae grown in ponds of sedimented animal waste and sewage. 46 references.

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

Directory of Open Access Journals (Sweden)

Tjeppy D Soedjana

2013-12-01

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

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.

2018-03-01

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.

Simulations at Czech poultry market

Directory of Open Access Journals (Sweden)

Lenka Rumánková

2012-01-01

Full Text Available This paper defines the possible scenarios of the development of the poultry market in the Czech Republic, in view of the trends in production, consumption and foreign trade. The individual scenarios are based upon the forecasts of selected factors that have a substantial impact on the poultry market and whose changes can be expected in the subsequent years with great likelihood. The article sets out and addresses various scenarios for the period of 2012–2014. The scenarios are based upon the partial equilibrium model of the poultry market, which has been derived on the basis of time series and panel data within the years 1995–2009. The conducted analysis clearly shows that changes in the prices of agricultural producers will have an effect on changes in the production of poultry meat, an increase in VAT through consumer prices will impact the rate of domestic consumption, as well as changes in disposable income. Similarly, a change in the exchange rate will have an effect on the amount of poultry imported into the Czech Republic.

Full Text Available Methods for determination of free water content in poultry meat are described in Commission Regulation EEC No 1538/91 as amended and in ČSN 57 3100. Two of them (method A and D have been validated in conditions of a Czech poultry processing plant. The capacity of slaughtering was 6000 pieces per hour and carcasses were chilled by air with spraying. All determinations were carried out in the plant’s lab and in the lab of the Institute of Food Technology. Method A was used to detect the amount of water lost from frozen chicken during thawing in controlled conditions. Twenty carcasses from six weight groups (900 g–1400 g were tested. The average values of thaw loss water contents ranged between 0.46% and 1.71%, the average value of total 120 samples was 1.16%. The results were compared with the required maximum limit value of 3.3%. The water loss content was in negative correlation with the weight of chicken (r = –0.56. Method D (chemical test has been applied to determine the total water content of certain poultry cuts. It involved the determination of water and protein contents of 62 representative samples in total. The average values of ratio of water weight to proteins weight WA/RPA were in breast fillets 3.29, in legs with a portion of the back 4.06, legs 4.00, thighs 3.85 and drumsticks 4.10. The results corresponded to the required limit values for breast fillets 3.40 and for leg cuts 4.15. The ratio of water weight to proteins weight WA/RPA was correlated with the weight of chicken for breast fillets negatively (r = –0.61 and for leg cuts positively (r = 0.70. Different correlations can be explained by the distribution of water, protein and fat in carcasses. The evaluation of methods in the parameter of percentage ratio of the average value to the limit showed that method D (results were at the level of 97% of the limit was more exact than method A (results were at the level 32% of the limit but it is more expensive.

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.

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.

2017-08-01

Campylobacteriosis is the most common cause of bacterial gastroenteritis worldwide. Consumption of poultry, especially chicken's meat is considered the most common route for human infection. The aim of this study was to determine if Campylobacter spp. might persist in the poultry plant environment before and after cleaning and disinfection procedures and the distribution and their genetic relatedness. During one month from a poultry plant were analyzed a total of 494 samples -defeathering machine, evisceration machine, floor, sink, conveyor belt, shackles and broiler meat- in order to isolate C. jejuni and C. coli. Results showed that C. jejuni and C. coli prevalence was 94.5% and 5.5% respectively. Different typing techniques as PFGE, MLST established seven C. jejuni genotypes. Whole genome MLST strongly suggest that highly clonal populations of C. jejuni can survive in adverse environmental conditions, even after cleaning and disinfection, and persist for longer periods than previous thought (at least 21 days) in the poultry plant environment. Even so, it might act as a source of contamination independently of the contamination level of the flock entering the slaughter line. Copyright © 2017 Elsevier Ltd. All rights reserved.

1995-01-01

Poultry litter has presented a waste disposal problem to the poultry industry in many parts of the United Kingdom. The plant at Eye is a small to medium scale power station, fired using poultry litter. The 12.7 MW of electricity generated is supplied, through the local utility, to the National Grid. The spent litter that constitutes the fuel is made up of excrement and animal bedding (usually 90% excrement and 10% straw or wood shavings). It comes from large climate-controlled buildings (broiler houses) where birds, reared for meat production, are allowed to roam freely. (UK)

Using annual serologic surveillance data from all poultry farms in the Netherlands during 2007-2013, we quantified the risk for the introduction of low pathogenicity avian influenza virus (LPAIV) in different types of poultry production farms and putative spatial-environmental risk factors: distance from poultry farms to clay soil, waterways, and wild waterfowl areas. Outdoor-layer, turkey (meat and breeder), and duck (meat and breeder) farms had a significantly higher risk for LPAIV introduction than did indoor-layer farms. Except for outdoor-layer, all poultry types (i.e., broilers, chicken breeders, ducks, and turkeys) are kept indoors. For all production types, LPAIV risk decreased significantly with increasing distance to medium-sized waterways and with increasing distance to areas with defined wild waterfowl, but only for outdoor-layer and turkey farms. Future research should focus not only on production types but also on distance to waterways and wild bird areas. In addition, settlement of new poultry farms in high-risk areas should be discouraged.

Raw poultry litter has certain drawbacks for energy production such as high ash and moisture content, a corrosive nature, and low heating values. A combined solution to utilization of raw poultry litter may involve fractionation and pyrolysis. Fractionation divides poultry litter into a fine, nutrient-rich fraction and a coarse, carbon-dense fraction. Pyrolysis of the coarse fraction would remove the corrosive volatiles as bio-oil, leaving clean char. This paper presents the effect of fractionation and pyrolysis process parameters on the calorific value of char and on the characterization of bio-oil. Poultry litter samples collected from three commercial poultry farms were divided into 10 treatments that included 2 controls (raw poultry litter and its coarse fraction having particle size greater than 0.85 mm) and 8 other treatments that were combinations of three factors: type (raw poultry litter or its coarse fraction), heating rate (30 or 10 degrees C/min), and pyrolysis temperature (300 or 500 degrees C). After the screening process, the poultry litter samples were dried and pyrolyzed in a batch reactor under nitrogen atmosphere and char and condensate yields were recorded. The condensate was separated into three fractions on the basis of their density: heavy, medium, and light phase. Calorific value and proximate and nutrient analysis were performed for char, condensate, and feedstock. Results show that the char with the highest calorific value (17.39 +/- 1.37 MJ/kg) was made from the coarse fraction at 300 degrees C, which captured 68.71 +/- 9.37% of the feedstock energy. The char produced at 300 degrees C had 42 +/- 11 mg/kg arsenic content but no mercury. Almost all of the Al, Ca, Fe, K, Mg, Na, and P remained in the char. The pyrolysis process reduced ammoniacal-nitrogen (NH4-N) in char by 99.14 +/- 0.47% and nitrate-nitrogen (NO3-N) by 95.79 +/- 5.45% at 500 degrees C.

2016-11-01

Full Text Available The purpose of this review is to present information about raw materials that can be used in pig and poultry diets and the factors responsible for variations in their mycotoxin contents. The levels of mycotoxins in pig and poultry feeds are calculated based on mycotoxin contamination levels of the raw materials with different diet formulations, to highlight the important role the stage of production and the raw materials used can have on mycotoxins levels in diets. Our analysis focuses on mycotoxins for which maximum tolerated levels or regulatory guidelines exist, and for which sufficient contamination data are available. Raw materials used in feed formulation vary considerably depending on the species of animal, and the stage of production. Mycotoxins are secondary fungal metabolites whose frequency and levels also vary considerably depending on the raw materials used and on the geographic location where they were produced. Although several reviews of existing data and of the literature on worldwide mycotoxin contamination of food and feed are available, the impact of the different raw materials used on feed formulation has not been widely studied.

The selection of broilers for augmented growth rate and breast has brought about wooden-breast (WB) muscle abnormalities, which caused substantial economic losses. The objective of this study was to compare water holding capacity, water mobility and distribution, salt-soluble protein (SSP) content, and protein profiles of normal and WB chicken meat with different additions of NaCl. Thirty WB and 30 normal chicken breasts were selected from a deboning line of a major Chinese processing plant at 2 to 3 h post mortem. Two different meat batters were formulated to 150 mg/g meat protein and different NaCl contents (0%, 1%, 2%, 3%, and 4%). Results indicated that as NaCl contents increased, the cooking loss of meat batters decreased (P meat showed different protein profiles, with myosin heavy chain exhibiting a higher intensity at ≥3% salt level. Low-field nuclear magnetic resonance (LF-NMR)revealed an increased T22 and higher P22 in raw WB meat compared to normal meat (P meat batters, WB meat batters had reduced T21 and lower immobilized water proportions at low NaCl contents (meat gels. Meat gels prepared from WB had a lower proportion of water within the myofibrillar protein matrix and a greater proportion of exuded bulk water at NaCl contents meat, meat batters and gels, water distribution and mobility of WB exhibited significant differences compared to normal meat. The addition of NaCl affected water mobility and distributions in meat batters, with a level of 3% NaCl eliminating the differences between processed normal and WB meat products. © 2017 Poultry Science Association Inc.

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.

2001-01-01

Studies were conducted to see the levels of important nutrients and selected essential/toxic metals in different types of meat i.e. beef, poultry, mutton and fish. The meat samples were also analyzed for bacterial contamination. Highest value of protein (20.32 +- 1.86% was detected in poultry (chicken) while maximum fats and fiber contents (13.50 +- 0.14 and 0.135 +- 0.112%) were found in beef samples. The Pb content was found to be 7.0 +- 0.61 (mutton), 6.6 +- 0.58 (beef) and 3.3 +- 0.39 ppm (poultry). The highest level of Cd was determined in poultry (1.00 +- 0.13) followed by mutton (0.80 +- 0.07), beef (0.70 +- 0.08) and fish (0.25 +- 0.04 ppm). The maximum level of Cu (10.0 +- 0.55 and 7.0 +- 0.43 ppm) was detected in beef and mutton respectively while comparatively low Cu content was found in poultry as well as fish samples. It was observed that fresh meat had low levels of heavy metals. Highest concentrations of Fe (3.29 +- 0.41ppm) and P (167.8 +- 10.31) were found in mutton and beef respectively. The data revealed that majority of meat samples were also contaminated with bacteria and showed presence of E. coli. Hence, were considered unfit for human consumption. In addition % moisture and ash were also examined. The results were compared with recommended daily allowances and some remedial measures to control environmental pollution of meat sold in the open air are suggested. (author)

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.

Nutritional Factors Affecting Abdominal Fat Deposition in Poultry: A Review

Science.gov (United States)

Fouad, A. M.; El-Senousey, H. K.

2014-01-01

The major goals of the poultry industry are to increase the carcass yield and to reduce carcass fatness, mainly the abdominal fat pad. The increase in poultry meat consumption has guided the selection process toward fast-growing broilers with a reduced feed conversion ratio. Intensive selection has led to great improvements in economic traits such as body weight gain, feed efficiency, and breast yield to meet the demands of consumers, but modern commercial chickens exhibit excessive fat accumulation in the abdomen area. However, dietary composition and feeding strategies may offer practical and efficient solutions for reducing body fat deposition in modern poultry strains. Thus, the regulation of lipid metabolism to reduce the abdominal fat content based on dietary composition and feeding strategy, as well as elucidating their effects on the key enzymes associated with lipid metabolism, could facilitate the production of lean meat and help to understand the fat-lowering effects of diet and different feeding strategies.

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.

Growth curves were evaluated for aerobic mesophilic and psychrotrophic bacteria, Pseudomonas spp. and Staphylococcus spp., grown in raw, salted, and cooked chicken breast at 2, 4, 7, 10, 15, and 20 ℃, respectively, using the modified Gompertz and modified logistic models. Shelf life was determined based on microbiological counts and sensory analysis. Temperature increase reduced the shelf life, which varied from 10 to 26 days at 2 ℃, from nine to 21 days at 4 ℃, from six to 12 days at 7 ℃, from four to eight days at 10 ℃, from two to four days at 15 ℃, and from one to two days at 20 ℃. In most cases, cooked chicken breast showed the highest microbial count, followed by raw breast and lastly salted breast. The data obtained here were useful for the generation of mathematical models and parameters. The models presented high correlation and can be used for predictive purposes in the poultry meat supply chain. © The Author(s) 2015.

Technological Feasibility of Preserving Meat, Poultry and Fish Products by Using a Combination of Conventional Additives, Mild Heat Treatment and Irradiation

Energy Technology Data Exchange (ETDEWEB)

Wierbicki, E. [United States Army Natick Research and Development Laboratory, Natick, MD (United States)

1981-09-15

Radappertization, or irradiation sterilization of meats and other protein foods (poultry, seafoods) is a new processing method applicable to pre-cooked (enzyme inactivated) foods that are hermetically sealed (either in metal cans, flexible pouches, or metal or plastic trays) and involves irradiation to sterilizing doses of either gamma rays (from a cobalt-60 or caesium-137 source) or by X-rays and electrons. The process is particularly applicable to pre-cooked meat, poultry, fin fish, and shellfish, as well as to dry foods, animal feed, and spices. The resulting radappertized products are free from food spoilage microorganisms and organisms of public health significance, including the pathogens such as C. botulinum, salmonellae, trichinae, etc. The radappertized products can be stored without refrigeration for long periods (years), the limiting factor being the integrity of the primary packaging material. Irradiation sterilization of cured meats allows complete elimination or a drastic reduction of incoming nitrite to the levels needed only for characteristic colour and flavour of the items while providing protection against C. botulinum by irradiation. The irradiated-cured products with the low levels of added nitrite are free from residual nitrite and nitrosamines, including nitrosopyrrolidine in fried bacon. In recent co-operative research with the US Department of Agriculture, it was shown that irradiation also destroys pre-formed nitrosamines in bacon. The technology of the process was developed by the US National Food Irradiation Program and the US Army from 1953 to 1980. The US Army spearheaded the development of this new technology to the point where the food irradiation potentials have become meaningful within the broad scope of national and international interests. Therefore, it was highly appropriate that, effective 1 October 1980, the responsibility for the programme at this stage was transferred to the US Department of Agriculture which has been

A simulated supermarket setting (SSS) test was conducted to determine whether consumers (n = 126) would purchase irradiated poultry products, and the effects of marketing strategies on consumer purchase of irradiated poultry products. Consumer preference for irradiated poultry was likewise determined using a home-use test. A slide program was the most effective educational strategy in changing consumers' purchase behavior. The number of participants who purchased irradiated boneless, skinless breasts and irradiated thighs after the educational program increased significantly from 59.5 and 61.9% to 83.3 and 85.7% for the breasts and thighs, respectively. Using a label or poster did not increase the number of participants who bought irradiated poultry products. About 84% of the participants consider it either 'somewhat necessary' or 'very necessary' to irradiate raw chicken and would like all chicken that was served in restaurants or fast food places to be irradiated. Fifty-eight percent of the participants would always buy irradiated chicken if available, and an additional 27% would buy it sometimes. About 44% of the participants were willing to pay the same price for irradiated chicken as for nonirradiated. About 42% of participants were willing to pay 5% or more than what they were currently paying for nonirradiated chicken. Seventy-three percent or more of consumers who participated in the home-use test (n = 74) gave the color, appearance, and aroma of the raw poultry products a minimum rating of 7 (= like moderately). After consumers participated in a home-use test, 84 and 88% selected irradiated thighs and breasts, respectively, over nonirradiated in a second SSS test

Tuomisto, Hanna L; de Mattos, M Joost Teixeira

2011-07-15

Cultured meat (i.e., meat produced in vitro using tissue engineering techniques) is being developed as a potentially healthier and more efficient alternative to conventional meat. Life cycle assessment (LCA) research method was used for assessing environmental impacts of large-scale cultured meat production. Cyanobacteria hydrolysate was assumed to be used as the nutrient and energy source for muscle cell growth. The results showed that production of 1000 kg cultured meat requires 26-33 GJ energy, 367-521 m(3) water, 190-230 m(2) land, and emits 1900-2240 kg CO(2)-eq GHG emissions. In comparison to conventionally produced European meat, cultured meat involves approximately 7-45% lower energy use (only poultry has lower energy use), 78-96% lower GHG emissions, 99% lower land use, and 82-96% lower water use depending on the product compared. Despite high uncertainty, it is concluded that the overall environmental impacts of cultured meat production are substantially lower than those of conventionally produced meat.

2016-09-01

The global poultry industry has been faced with emerging broiler breast meat quality issues including conditions known as white striping (WS, white striations parallel to muscle fibers) and woody breast (WB, hardness of raw fillet). Experiments were conducted to evaluate effects of WS and WB hardness on meat quality traits in broiler breast fillets. In Exp. 1, birds were processed at approximately 9 wk of age and deboned at 4 h postmortem (PM); in Exp. 2, birds were processed at approximately 6 and 9 wk of age and deboned at 2 h PM. Fillets were categorized as: normal for both white striping and woody breast (NORM); moderate for white striping and mild for woody breast (MILD); severe for white striping and mild for woody breast (WS); severe for woody breast and moderate for white striping (WB); or severe for both white striping and woody breast (BOTH). Sarcomere length, gravimetric fragmentation index, marination uptake, cook loss, and Meullenet-Owens razor shear energy (MORSE) values on non-marinated and marinated fillets were assessed. Sarcomeres tended to be longer (P = 0.07) with increasing severity of WS and WB in both experiments and gravimetric fragmentation index did not differ (P > 0.05) among categories. Marinade uptake decreased (P  0.05) in non-marinated fillets, the marinated BOTH fillets had greater MORSE values (P  0.05) among categories of marinated breasts. At 9 wk, WS and BOTH were higher (P white striping and woody breast, individually or in combination, negatively impact meat quality, especially water holding capacity attributes such as marinade uptake and cook loss. © 2016 Poultry Science Association Inc.

The present study evaluates the presence of Listeria spp and particularly of L. monocytogenes in bovine, pork and poultry meats sold by retail in supermarkets and butchers in the city of Cassino. The sensibility to the antibiotics mostly used in the veterinary practice has been tested on the isolated strains. The different species of Listeria have shown a considerable variation of isolation based on the meat's typology and on the different store's provenance. Moreover our results show greater degree of contamination than the data currently available the Italian literature. In our study poultry meat is the most contaminated one. We can assert that omissions and poor caring errors in the manipulation and conservation of meat expose the customer to an even higher risk of infection.

In this study, total mercury (THg) and methylmercury (MeHg) concentrations in muscles (leg and breast), organs (intestine, heart, stomach, liver) and blood were investigated for backyard chickens, ducks and geese of the Wanshan Mercury Mine, China. THg in poultry meat products range from 7.9 to 3917.1 ng/g, most of which exceeded the Chinese national standard limit for THg in meat (50 ng/g). Elevated MeHg concentrations (0.4–62.8 ng/g) were also observed in meat products, suggesting that poultry meat can be an important human MeHg exposure source. Ducks and geese showed higher Hg levels than chickens. For all poultry species, the highest Hg concentrations were observed in liver (THg: 23.2–3917.1 ng/g; MeHg: 7.1–62.8 ng/g) and blood (THg: 12.3–338.0 ng/g; MeHg: 1.4–17.6 ng/g). We estimated the Hg burdens in chickens (THg: 15.3–238.1 μg; MeHg: 2.2–15.6 μg), ducks (THg: 15.3–238.1 μg; MeHg: 3.5–14.7 μg) and geese (THg: 83.8–93.4 μg; MeHg: 15.4–29.7 μg). To not exceed the daily intake limit for THg (34.2 μg/day) and MeHg (6 μg/day), we suggested that the maximum amount (g) for chicken leg, breast, heart, stomach, intestine, liver, and blood should be 1384, 1498, 2315, 1214, 1081, 257, and 717, respectively; the maximum amount (g) for duck leg, breast, heart, stomach, intestine, liver, and blood should be 750, 1041, 986, 858, 752, 134, and 573, respectively; and the maximum amount (g) for goose leg, breast, heart, stomach, intestine, liver, and blood should be 941, 1051, 1040, 1131, 964, 137, and 562, respectively. - Highlights: • Elevated mercury levels were observed in poultry from Wanshan Mercury Mine, China. • Ducks and geese showed higher mercury levels than chickens. • Liver and blood showed the highest mercury levels. • Poultry can be an important dietary Hg exposure source for local residents. - High levels of Hg associated with poultry surrounding the Wanshan Mercury Mine pose a great risk of Hg exposure to

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.

Blue Water Footprint Management in a UK Poultry Supply Chain under Environmental Regulatory Constraints

Directory of Open Access Journals (Sweden)

2018-02-01

Full Text Available Chicken is the most consumed meat in the UK, accounting for 40% of meat consumption, while national production sufficiency reaches about 80%. As a farmed animal product, chicken meat is responsible for significant freshwater appropriation volumes during its production cycle. In this context, this research aims at exploring freshwater dynamics in the UK processed poultry industry. Specifically, we develop a System Dynamics model to capture the blue water footprint, as a key sustainability performance indicator of a poultry supply chain, in the case that relevant environmental and regulatory constraints are applied. The model contributes towards investigating the impact of two potential policy-making scenarios, namely, the “water penalty” and the “water tax”, on the nexus between profitability and water usage across the poultry supply chain. Responding to the regulatory constraints, the food processor either reconfigures the supply chain through rethinking desired inventory levels or implements a water management intervention. The results indicate that investing in water-friendly production technologies could offer a greater advantage to sustainable supply chains in terms of blue water efficiency and profitability, compared to employing inventory management strategies. Overall, our analysis highlights that effective policy-making and technology-driven interventions could provide potential towards ensuring economic growth and environmental sustainability of the UK poultry sector.

Since meat may be involved in the etiology of colorectal cancer, associations between meat-related compounds were examined to elucidate underlying mechanisms in a population-based case-control study. Participants (989 cases/1,033 healthy controls) completed a food frequency questionnaire with a meat-specific module. Multivariable logistic regression was used to examine associations between meat variables and colorectal cancer; polytomous logistic regression was used for subsite-specific analyses. The following significant positive associations were observed for meat-related compounds: 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx) and colorectal, distal colon, and rectal tumors; 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) and colorectal and colon cancer tumors; nitrites/nitrates and proximal colon cancer; 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and rectal cancer; and benzo[a]pyrene and rectal cancer (P-trends cancer and pan-fried red meat and colorectal cancer were found (P-trends cancer; and well-done/charred poultry and colorectal, colon, and proximal colon tumors (P-trends nitrates may be involved in colorectal cancer etiology.

Poortvliet, P M; Ekkel, E D; Kemp, B; Stassen, E N

2018-01-01

Abstract Differences in risk perceptions of public health and food safety hazards in various poultry husbandry systems by various stakeholder groups, may affect the acceptability of those husbandry systems. Therefore, the objective was to gain insight into risk perceptions of citizens, poultry farmers, and poultry veterinarians regarding food safety and public health hazards in poultry husbandry systems, and into factors explaining these risk perceptions. We surveyed risk perceptions of Campylobacter contamination of broiler meat, avian influenza introduction in laying hens, and altered dioxin levels in eggs for the most commonly used broiler and laying hen husbandry systems in Dutch citizens (n = 2,259), poultry farmers (n = 100), and poultry veterinarians (n = 41). Citizens perceived the risks of the three hazards in the indoor systems higher and in the outdoor systems lower than did the professionals. Citizens reported higher concerns regarding aspects reflecting underlying psychological factors of risk perception compared to professionals. Professionals indicated a relatively low level of personal control, which might imply risk denial. Of the socio-demographic characteristics, gender and childhood residence were associated with risk perceptions. The influence of other factors of risks perception are discussed. It is suggested that risk perceptions of all stakeholder groups are influenced by affect, stigma, and underlying values. To adapt current or new husbandry systems that can count on societal support, views of key stakeholders and multiple aspects such as animal welfare, public health, food safety, and underlying values should be considered integrally. When trade-offs, such as between animal welfare and public health have to be made, insight into underlying values might help to find consensus among stakeholders. PMID:29161444

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.

Effects of gamma irradiation on the survival of Listeria monocytogenes and on its growth at refrigeration temperature in poultry and red meat

International Nuclear Information System (INIS)

Gursel, B.; Gurakan, G.C.

1997-01-01

Gamma irradiation sensitivity of a strain of Listeria monocytogenes was determined in trypticase soy broth supplemented with yeast extract (TSB-YE), in a slurry of chicken breast meat and in raw ground beef. D10 values in these different media were 0.364, 0.599, and 0.699 kGy, respectively. This organism appeared most sensitive in TSB-YE, more resistant in minced fresh chicken breast meat, and most resistant in fresh minced beef. It was found that irradiation at 2.5 kGy prior to refrigeration is an efficient way for the preservation of meat products contaminated at 10(3) to 10(4) per gram initial load of L. monocytogenes for about 7 d. However, with this initial load, the injured cells might repair themselves and cause a health hazard during storage at 4 C in the presence of air after 7 d

2012-01-01

Salmonella is a globally widespread food-borne pathogen having major impact on public health. All motile serovars of Salmonella enterica of poultry origin are zoonotic, and contaminated meat and raw eggs are an important source to human infections. Information on the prevalence of Salmonella at farm/holding level, and the zoonotic serovars circulating in layer poultry in the South and South-East Asian countries including Bangladesh, where small-scale commercial farms are predominant, is limited. To investigate the prevalence of Salmonella at layer farm level, and to identify the prevalent serovars we conducted a cross-sectional survey by randomly selecting 500 commercial layer poultry farms in Bangladesh. Faecal samples from the selected farms were collected following standard procedure, and examined for the presence of Salmonella using conventional bacteriological procedures. Thirty isolates were randomly selected, from the ninety obtained from the survey, for serotyping and characterized further by plasmid profiling and pulsed-field gel electrophoresis (PFGE). Results of the survey showed that the prevalence of motile Salmonella at layer farm level was 18% (95% confidence interval 15–21%), and Salmonella Kentucky was identified to be the only serovar circulating in the study population. Plasmid analysis of the S. Kentucky and non-serotyped isolates revealed two distinct profiles with a variation of two different sizes (2.7 and 4.8 kb). PFGE of the 30 S. Kentucky and 30 non-serotyped isolates showed that all of them were clonally related because only one genotype and three subtypes were determined based on the variation in two or three bands. This is also the first report on the presence of any specific serovar of Salmonella enterica in poultry in Bangladesh. PMID:22558269

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.

2015-01-01

Phosphorus (P) may be immobilized and consequently the runoff loss risks be reduced if poultry litter (PL) is converted into biochar prior to land application. Laboratory studies were conducted to examine the water extractability of P in PL biochar and its release kinetics in amended soils. Raw PL and its biochar produced through 400 °C pyrolysis were extracted with deionized water under various programs and measured for water extractable P species and contents. The materials were further incubated with a sandy loam at 20 g kg −1 soil and intermittently leached with water for 30 days. The P release kinetics were determined from the P recovery patterns in the water phase. Pyrolysis elevated the total P content from 13.7 g kg −1 in raw PL to 27.1 g kg −1 in PL biochar while reduced the water-soluble P level from 2.95 g kg −1 in the former to 0.17 g kg −1 in the latter. The thermal treatment transformed labile P in raw PL to putatively Mg/Ca phosphate minerals in biochar that were water-unextractable yet proton-releasable. Orthophosphate was the predominant form of water-soluble P in PL biochar, with condensed phosphate (e.g., pyrophosphate) as a minor form and organic phosphate in null. Release of P from PL biochar in both water and neutral soils was at a slower and steadier rate over a longer time period than from raw PL. Nevertheless, release of P from biochar was acid-driven and could be greatly promoted by the media acidity. Land application of PL biochar at soil pH-incorporated rates and frequency will potentially reduce P losses to runoffs and minimize the adverse impact of waste application on aquatic environments. - Highlights: • The predominant portion of P in poultry litter biochar is water insoluble. • Poultry litter P was immobilized by forming Ca/Mg (pyro)phosphates in biochar. • Release of P from biochar was slower and steadier than from raw poultry litter. • Soil pH greatly influenced the P release patterns of poultry litter biochar

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

1994-01-01

The effect of gamma rays on tissue level changes of unbound tyrosine and tetracycline was examined in comparative trials with broiler chicken meat. White meat and dark meat samples were taken from the killed chicken and were frozen at -18 o C. The three experimental groups were gamma irradiated with doses of 1.0, 1.5 and 2 kGy. The contents of the unbound antibiotics were microbiologically tested on 24th hour and 45th day after irradiation using Bacillus subtilis ATCC 6633, respectively Bac. mycoides HB 2 as test organisms. It was found that on 25th hour after irradiation both antibiotics were not significantly changed compared to the controls. After 45 days of storage a tendency towards decreasing the antibiotic concentrations in both the white and dark meat had been detected. (author)

Full Text Available In the technology of traditional and new forms of food, the modification of structure of proteins is carry out in two opposite directions: the hydrolytic destruction of high-molecular polymers and the artificial creation of polymeric structures of high molecular mass. The transglutaminase preparations (protein-glutamine (-glutamyltransferase, EC 2.3.2.13, TG are used in practical work for realization of the second direction. The main mechanisms of action are polymerization reactions, which lead to a change in the hydrophobicity of protein molecules. The main catalyzed reactions are acyl transfer, binding between glutamine and lysine residues of proteins and deamination. The authors analyzed the approaches to the preparation, properties and studied the joint effect of temperature and pH on the activity of the commercial preparation Revada TG 11 with the application of an enzymatic colorimetric test. The authors studied combined stuffing systems based on beef, pork, poultry mechanical deboning, as well as replacing part of the raw material with protein-carbohydrate compositions with Revada TG 11. The results were used to develop simulated meat systems of biopolymer compositions (SMSBC, approximate in structure and properties to the gels formed by actin and myosin during extraction from myofibrils under the traditional technological processes of meat products production - maturation, salt curing, fine meat grinding. SMSBC includes lupine flour bio-activated by germination, a preparations of dietary fiber as well as a preparation of transglutaminase Revada TG 11. The protein components of the secondary raw materials during the processing of milk such as sodium caseinate, and also whey were used to balance the amino acid composition of the food systems. For practical use, the following options for SMSBC introducing into the composition of minced meat emulsions were recommended by the authors: in the form of hydrated biopolymer dispersion at cutting

Wageningen Economic Research conducted a study on the potential consequences of a free trade agreement between Mexico and the EU. The Dutch government is concerned that giving access to products from countries with a lower level of animal welfare could undermine the EU welfare standard. This study shows that production costs are lower in Mexico compared to the EU in all three sectors investigated: egg production, poultry meat and pig meat. In egg production in particular, the welfare standard...

The USDA Food Safety and Inspection Service determined populations of bacteria on poultry during processing at a slaughter plant in Puerto Rico in November and December 1987. The plant was selected because of its management's willingness to support important changes in equipment and processing procedures. The plant was representative of modern slaughter facilities. Eight-hundred samples were collected over 20 consecutive 8-hour days of operation from 5 sites in the processing plant. Results indicated that slaughter, dressing, and chilling practices significantly decreased the bacterial contamination on poultry carcasses, as determined by counts of aerobic bacteria, Enterobacteriaceae, and Escherichia coli. Salmonella was not enumerated; rather, it was determined to be present or absent by culturing almost the entire rinse. The prevalence of Salmonella in the study decreased during evisceration, then increased during immersion chilling.

Proliferation of microbial population on fresh poultry meat over time elicits spoilage when reaching unacceptable levels, during which process slime production, microorganism colony formation, negative organoleptic impact and meat structure change are observed. Spoilage organisms in raw meat, especially Gram-negative bacteria can be difficult to combat due to their cell wall composition. In this study, the natural antimicrobial agents ε-poly-L-lysine (ε-PL) and isoeugenol were tested individually and in combinations for their activities against a selection of Gram-negative strains in vitro. All combinations resulted in additive interactions between ε-PL and isoeugenol towards the bacteria tested. The killing efficiency of different ratios of the two antimicrobial agents was further evaluated in vitro against Pseudomonas putida. Subsequently, the most efficient ratio was applied to a raw turkey meat model system which was incubated for 96 h at spoilage temperature. Half of the samples were challenged with P. putida, and the bacterial load and microbial community composition was followed over time. CFU counts revealed that the antimicrobial blend was able to lower the amount of viable Pseudomonas spp. by one log compared to untreated samples of challenged turkey meat, while the single compounds had no effect on the population. However, the compounds had no effect on Pseudomonas spp. CFU in unchallenged meat. Next-generation sequencing offered culture-independent insight into population diversity and changes in microbial composition of the meat during spoilage and in response to antimicrobial treatment. Spoilage of unchallenged turkey meat resulted in decreasing species diversity over time, regardless of whether the samples received antimicrobial treatment. The microbiota composition of untreated unchallenged meat progressed from a Pseudomonas spp. to a Pseudomonas spp., Photobacterium spp., and Brochothrix thermosphacta dominated food matrix on the expense of low

Full Text Available Poultry meat is one of the most important sources of infection of Yersinia spp. for humans. The aim of the present study was to evaluate the incidence of Yersinia enterocolitica in chicken meat by using culture method on selective medium and confirmation by PCR assay. Also, biochemical methods were used for biotyping. A total of 100 chicken thigh meat samples were collected randomly from retail outlets in Mashhad, Iran. Samples were enriched in Peptone-Sorbitol-Bile (PSB broth and then cultured on Cefsulodin-Irgasan-Novobiocin (CIN agar containing antibiotics supplement. The DNA was extracted from suspected colonies of Yersinia spp. and then PCR test using specific primers for 16S rRNA gene of Yersinia enterocolitica was performed. In this study, 30% of chicken meat was contaminated with Yersinia spp. by culture method and 25% of chicken meat was contaminated with Yersinia enterocolitica. Biotyping of isolated colonies showed that all of the isolates belonged to biotype 1A. Culture and detection of Yersinia spp. from food samples traditionally take 4 days. Due to high accuracy and speed of PCR assay, it is a good alternative method for microbiological techniques. In conclusion, poultry meat can act as a source of Y. enterocolitica and could be considered as a public health hazard.

NAFTA AT 21: STRUCTURAL CHANGE IN MEXICAN’S DEMAND FOR U.S. MEAT AND MEAT PRODUCTS

Full Text Available The purpose of this paper is to examine the influence of the North American Free Trade Agreement (NAFTA on the change in consumer preference for U.S. meat and meat products in Mexico and to provide empirical estimates of the extent of sensitivity of meat price change to change in quantity demand. The analyses used an Inverse Almost Ideal Demand System (IAIDS model to address the study objectives due to its appropriateness in modeling the level of utility for commodities with fixed or exogenously determined short run supply. The study findings show that Mexico’s participation in NAFTA could have indirectly effected a structural change in demand for imported meat from the U.S. but the direction of change is heterogeneous among the different meat groups. Also, while Mexican demand for U.S. meat is inflexible, price response to changes in the quantity of imported U.S. poultry is much sensitive compared to pork and beef.

McDonnell, Lindsey M; Glass, Kathleen A; Sindelar, Jeffrey J

2013-08-01

The objective of this study was to identify ingredients that inhibit Listeria monocytogenes in natural, organic, or clean-label ready-to-eat meat and poultry products. Fourteen ingredients were screened in uncured (no-nitrate-or-nitrite-added), traditional-cured (156 ppm of purified sodium nitrite), cultured (alternative cured, natural nitrate source, and Staphylococcus carnosus), or preconverted (alternative cured, natural nitrite source) turkey slurries. Slurries were cooked, cooled, inoculated to yield 3 log CFU/ml L. monocytogenes, stored at 4°C, and tested weekly for 4 weeks. Three antimicrobial ingredients, 1.5 % vinegar-lemon-cherry powder blend, 2.5 % buffered vinegar, and 3.0 % cultured sugar-vinegar blend, were incorporated into alternative-cured ham and uncured roast beef and deli-style turkey breast. Controls included all three meat products without antimicrobial ingredients and a traditional-cured ham with 2.8 % sodium lactate-diacetate. Cooked, sliced products were inoculated with 3 log CFU/g L. monocytogenes, vacuum packed, and stored at 4 or 7°C, for up to 12 weeks. For control products without antimicrobial agents stored at 4°C, a 2-log L. monocytogenes increase was observed at 2 weeks for ham and turkey and at 4 weeks for roast beef. Growth (>1-log increase) in the sodium lactate-diacetate was delayed until week 6. Compared with the control, the addition of either vinegar-lemon-cherry powder blend or buffered vinegar delayed L. monocytogenes growth for an additional 2 weeks, while the addition of cultured sugar-vinegar blend delayed growth for an additional 4 weeks for both ham and turkey. The greatest L. monocytogenes delay was observed in roast beef containing any of the three antimicrobial ingredients, with no growth detected through 12 weeks at 4°C for all the treatments. As expected, L. monocytogenes grew substantially faster in products stored at 7°C than at 4°C. These data suggest that antimicrobial ingredients from a natural source

INFLUENCE OF AUTOLYTIC TRANSFORMATIONS ON ELECTROPHYSICAL PROPERTIES OF GOAT MEAT

Full Text Available Functional foods represented an important element of a balanced, healthy diet. They play an important role in improving the structure of the diet of the population, are a means of prevention, correction and prevention of early transition premorbid conditions and various diseases. Meat and meat products based on it can be considered as a promising raw material for functional foods. Goat has certain dietary properties and can be used in manufacturing, but the production of high-grade products from goat meat, capable of long-term storage is not well developed. The chemical composition of the new raw meat - goat meat, on the example of the longissimus muscle of back is rich in protein, moisture, ash, and low-fat compared with other types of raw meat, which lets you create based on goat meat sector wide functional meat products. Therefore investigated the possibility of using goat meat in the production technology of functional foods. Showing the prospects for the development of goat in Russia.

Krishnan, K R; Sharma, N

1990-01-01

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.

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.

2016-01-01

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.

A response surface experimental design was employed to estimate residual nitrite level at various initial nitrite concentrations, percent turkey meat in the formula, and heat quantity (F) values using a typical wiener as the test system. Pork and mechanically separated turkey were used as the meat ingredients. Residual nitrite and pH were measured at day 1, 7 days, 14 days, and 49 days after processing. Protein, fat, salt, moisture, and CIE (L*a*b*) color values were also determined. Results showed that the effect of turkey meat on residual nitrite level was significant (P meat in the formula resulted in lower residual nitrite levels at a fixed pH. The residual nitrite level was initially proportional to initial nitrite concentration, but it became a nonsignificant factor during longer storage time. Differences in heat quantity had a significant effect (P nitrite level initially. Greater heat quantity decreased residual nitrite level in finished cured meat products at a fixed pH. However, this effect became nonsignificant during longer storage. Reduction of residual nitrite in wieners because of turkey meat addition at a fixed pH was due to characteristics of the turkey tissue, but the mechanism of action remains unknown. It was also established that commercial wieners had a higher pH if poultry meat was included in the formulation.

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.

Health and Welfare in Organic Poultry Production

2002-03-01

Full Text Available This review paper deals with the major health and welfare aspects of organic poultry production. The differences between organic and conventional egg and poultry meat production are discussed, with the main emphasis on housing and management requirements, feed composition and the use of veterinary prophylactic and therapeutic drugs. The effects of the legislation and statutes for organic farming on the health and welfare of the birds are also discussed, especially in relation to the biosecurity problems associated with free-range systems, the occurrence of behavioural disturbances in loose housed flocks and the use of veterinary drugs and vaccinations in general. The results from a questionnaire sent out to all Swedish organic egg producers, where questions about the farmer's perception of the birds' health status were included, are presented at the end of the paper. It is concluded that most of the health and welfare problems seen in conventional poultry systems for loose housed or free ranging birds can also been found on organic poultry farms. It is also concluded that there is a need for information about biosecurity, disease detection and disease prevention on organic poultry farms.

The effects of mechanically deboned poultry meat (MDPM) and levels of collagen fibers on comminuted, cooked sausage quality characteristics were investigated using the central composite rotatable design of response surface methodology (RSM). Use of collagen fiber as an additive affected the sausage characteristics, but the effect depended on the amount of the MDPM used. While MDPM additions resulted in higher cooking loss and darker and redder frankfurters, the addition of collagen fibers improved cooking yields and contributed to the lightness of the final product. Higher collagen fiber content was also accompanied by a significant increase in frankfurter hardness regardless of the MDPM content. Use of collagen fibers countered the negative effects of MDPM on sausage quality attributes, especially on cooking yields and final product color. Copyright © 2011 Elsevier Ltd. All rights reserved.

Full Text Available The use of natural origin antioxidants presents in fruit peels like prunes and its application to a meat product were analyzed. Phenolic compound concentration and antioxidant activity were determined to an ethanolic extract of prunes peels. A polyphenols concentration of 84 ug/g was found in the prunes peels extract with an antioxidant activity of 65.77% (TEAC. Two batches of cooked sausages were elaborated (pork meat and poultry paste, adding 5% of dehydrated prunes peels to sausages formulation to determinate the oxidative rancidity (TBA during 14 days of refrigerated storage. Sausageselaborated with poultry paste presented higher amount of malonaldehyde, indicating a higher tendency to lipid oxidation as compared to pork sausages. In same way, the incorporation ofprunes peels decreased oxidative rancidity since the content of antioxidant compounds delayed this process in processed meat products during storage.

How can we improve the environmental sustainability of poultry production?

Science.gov (United States)

Leinonen, Ilkka; Kyriazakis, Ilias

2016-08-01

The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environmental impacts, such as global warming, eutrophication and acidification. Amongst different sub-processes, feed production and transport contributes about 70 % to the global warming potential of poultry systems, whereas manure management contributes about 40-60 % to their eutrophication potential and acidification potential, respectively. All these impacts can be reduced by improving the feed efficiency, either by changing the birds through genetic selection or by making the feed more digestible (e.g. by using additives such as enzymes). However, although genetic selection has the potential to reduce the resources needed for broiler production (including feed consumption), the changing need of certain feed ingredients, most notably protein sources as a result of changes in bird requirements may limit the benefits of this strategy. The use of alternative feed ingredients, such as locally grown protein crops and agricultural by-products, as a replacement of South American grown soya, can potentially also lead to improvements in several environmental impact categories, as long as such feeding strategies have no negative effect on bird performance. Other management options, such as improving poultry housing and new strategies for manure management have also the potential to further improve the environmental sustainability of the poultry industries in Europe.

Effect of irradiation dose and irradiation temperature on the thiamin content of raw and cooked chicken breast meat

International Nuclear Information System (INIS)

Graham, W.D.; Stevenson, M.H.; Stewart, E.M.

1998-01-01

The usefulness of ionising radiation for the elimination of pathogenic bacteria in poultry meat has been well documented as have the effects of this processing treatment on the nutritional status of the food, in particular, the vitamins. Unfortunately, much of the earlier research carried out on the effect of irradiation on vitamins was carried out in solution or in model systems at doses much greater than those used commercially thereby resulting in considerable destruction of these compounds. Thus, those opposed to the process of food irradiation labelled the treated food as nutritionally poor. However, in reality, due to the complexity of food systems the effects of irradiation on vitamins are generally not as marked and many processes, for example cooking, cause the same degree of change to the vitamins. Thiamin (vitamin B1) is the most radiation sensitive of the water-soluble vitamins and is therefore a good indicator of the effect of irradiation treatment. In this study the effects of irradiation at either 4°C or −20°C followed by cooking on the thiamin content of chicken breast meat was determined. Results showed that whilst both irradiation and cooking resulted in a decrease in thiamin concentration, the losses incurred were unlikely to be of nutritional significance and could be further minimised by irradiating the chicken meat at a low temperature. Thiamin analyses were carried out using high-performance liquid chromatography since this technique is faster and more selective than the chemical or microbiological methods more commonly employed. Total thiamin, both free and combined form, was determined following acid and enzyme hydrolysis. © 1998 Society of Chemical Industry

ENRICHMENT OF POULTRY PRODUCTS WITH FUNCTIONAL INGREDIENTS

Directory of Open Access Journals (Sweden)

Gordana Kralik

2012-06-01

Full Text Available Primary role of food is to provide nutritive stuffs in sufficient amounts to meet nutritive requirements. However, recent scientific findings confirm assumptions that particular food or its ingredients had positive physiological and psychological effects on health. Functional food is referred to food rich in ingredients, having beneficial effects on one or more functions in an organism. By consuming functional food consumers can expect some health benefits. Production of poultry products as functional food is getting more important on foreign markets while portion of such products on domestic food market is insignificant. The aim of this paper is to present possibilities for enrichment of poultry products, such as broiler and turkey meat and chicken eggs, as they can be characterized as functional food. Functional ingredients in poultry products are polyunsaturated fatty acids (LNA, EPA and DHA and antioxidants. Enrichment of poultry products with the stated ingredients that are beneficial for human health is subject of many researches, and only recently have researches been directed towards assessment of market sustainability of such products.

Use of artificial intelligence in the production of high quality minced meat

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

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.

There are many slaughter procedures that religions and cultures use around the world. The two that are commercially relevant are the halal and kosher methods practiced by Muslims and Jews respectively. The global trade in red meat and poultry produced using these two methods is substantial, thus the importance of the quality of the meat produced using the methods. Halal and kosher slaughter per se should not affect meat quality more than their industrial equivalents, however, some of their associated pre- and post-slaughter processes do. For instance, the slow decline in blood pressure following a halal pre-slaughter head-only stun and neck cut causes blood splash (ecchymosis) in a range of muscles and organs of slaughtered livestock. Other quality concerns include bruising, hemorrhages, skin discoloration and broken bones particularly in poultry. In addition to these conventional quality issues, the "spiritual quality" of the meat can also be affected when the halal and kosher religious requirements are not fully met during the slaughter process. The nature, causes, importance and mitigations of these and other quality issues related to halal and kosher slaughtering and meat production using these methods are the subjects of this review.

Proteomics can be used to characterize quality defects including pale, soft, and exudative (PSE) meat (pork and poultry), woody broiler breast meat, reddish catfish fillets, meat toughness, and beef myoglobin oxidation. PSE broiler meat was characterized by 15 proteins that differed in abundance in comparison to normal broiler breast meat, and eight proteins were differentially expressed in woody breast meat in comparison to normal breast meat. Hemoglobin was the only protein that was differentially expressed between red and normal catfish fillets. However, inducing low oxygen and/or heat stress conditions to catfish fillets did not lead to the production of red fillets. Proteomic data provided information pertaining to the protein differences that exist in meat quality defects. However, these data need to be evaluated in conjunction with information pertaining to genetics, nutrition, environment of the live animal, muscle to meat conversion, meat quality analyses and sensory attributes to understand causality, protein biomarkers, and ultimately how to prevent quality defects.

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. In the fully adjusted Cox regression model, the relative risks of CVD across increasing quintiles of total unprocessed meat intake were 1.0 (reference, 0.72 (95% confidence interval (CI: 0.55, 0.95, 0.57 (95% CI: 0.42, 0.78, 0.69 (95% CI: 0.51, 0.95, and 0.69 (95% CI: 0.48, 0.97, but no significant linear trend was detected (p for trend = 0.14. Frequent poultry consumption was significantly associated with a decreased CVD risk; this association showed a dose-response relationship (p for trend = 0.04. This study showed that a moderate intake of total unprocessed meat was inversely associated with CVD risk. A significant inverse association between poultry consumption and incident CVD was observed in Korean adults, requiring further confirmation in other populations.

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.

Full Text Available In Taiwan, Angiostrongylus cantonensis infection has been reported in foreign laborers who had consumed raw Ampullarium canaliculatus snails. This study analyzed three foreign laborers who had contracted enzyme-linked immunosorbent assay-confirmed A cantonensis infection while working in Taiwan. All three workers had consumed either roasted snails or raw snails flavored with seasoning while drinking wine. This study investigated possible risk factors for A cantonensis, including naturally occurring A cantonensis in A canaliculatus snails, viability of third-stage A cantonensis larvae in raw seasoned snails and in roasted snails, infectivity of larvae, and effects of alcohol while consuming snails. Positive infection rates in snails from five different irrigation canals in south Taiwan ranged from 12.3% to 29.4% and the average number of motile larvae per infected snail ranged from 36 to 65. The number of motile and coiled larvae in snail meat after 120 minutes seasoning was 93 (27.7% and 233 (69.3%, respectively. After 20 minutes of roasting, most larvae in the snail meat were dead. The infectivities of motile and coiled larvae from snail meat after 60 minutes seasoning were 53.2% and 33.2%, respectively, and those from snail meat after 5 minutes roasting were 33.2% and 7.0%, respectively. Eating Taiwan A canaliculatus snails raw is extremely risky given their high infection rates and infection intensities. Even after 120 minutes seasoning or after 20 minutes roasting, snail meat should be considered unsafe for human consumption. Finally, experimental rodent studies indicated that consuming alcohol while ingesting larvae does not significantly reduced infectivity.
