The studies on the influence of radiation treatment of carcasses from the stress-resistant and stress-sensitive broiler chickens on the thermophysical properties of raw meat are presented. An increase in thermal diffusivity of meat from the stress-resistant poultry by 24.7 % and 54.7 % after radiation treatment of carcasses with ionizing radiation doses of 9 kGy and 12 kGy, respectively, was established. In meat from the stress-sensitive poultry, this figure increased by 33.3 % and 35.8 % compared to the untreated carcasses.It is shown that radiation treatment of carcasses by applied doses increased the thermal conductivity coefficient of meat from the stressresistant poultry by 5.3% and 7.0 %; in meat from the stress-sensitive poultry, this figure increased by 2.0 and 6.2 times compared to meat from the carcasses not exposed to radiation. At the same time, the value of the heat capacity coefficient was reduced. The irradiated poultry meat samples accumulate energy of ionizing radiation more intensively, which allows the intensification of the thermal processes occurring at various stages of meat product production. Treatment of meat from the stress-resistant poultry with ionizing radiation can reduce the amount of meat with non-traditional autolysis due to changes in its functionaltechnological properties. The results of the research should be taken into account in technological processes in the production of meat products with non-traditional autolysis.

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

The aim of our study was to investigate the microbial quality of meat products and on some clinical samples in Abidjan focused onStaphylococcusgenus and the toxin production profile ofStaphylococcus aureus(S. aureus) isolated. Bacteria were collected from 240 samples of three meat products sold in Abidjan and 180 samples issued from clinical infections. The strains were identified by both microbiological and MALDI-TOF-MS methods. The susceptibility to antibiotics was determined by the disc diffusion method. The production of Panton-Valentine Leukocidin, LukE/D, and epidermolysins was screened using radial gel immunodiffusion. The production of staphylococcal enterotoxins and TSST-1 was screened by a Bio-Plex Assay. We observed that 96/240 of meat samples and 32/180 of clinical samples were contaminated byStaphylococcus. Eleven species were isolated from meats and 4 from clinical samples. Forty-twoS. aureusstrains were isolated from ours samples. Variability of resistance was observed for most of the tested antibiotics but none of the strains displays a resistance to imipenem and quinolones. We observed that 89% of clinicalS. aureuswere resistant to methicillin against 58% for those issued from meat products. AllS. aureusisolates issued from meat products produce epidermolysins whereas none of the clinical strains produced these toxins. The enterotoxins were variably produced by both clinical and meat product samples.

Campylobacter is the leading cause of human bacterial diarrhoeal disease worldwide, with poultry meat products accounting for the majority of human cases. Recent surveys by the Food Standards Agency estimate the Campylobacter prevalence in fresh UK retail chicken to be 41.2%. However, such surveys have not distinguished between broiler chickens produced for different consumer demographics, such as the Halal market. Campylobacter colonisation of broilers is difficult to prevent, especially during routine partial depopulation of flocks. Broilers produced for the Halal market may undergo multiple depopulation events, which may increase the risk of colonisation and subsequent Campylobacter contamination of chicken meat. This project aimed to determine the prevalence and levels of Campylobacter contamination of chicken meat produced for the UK Halal market. Campylobacter was identified and enumerated from the neck skin and outer packaging of 405 Halal chickens. Following culture, isolates were assigned to species via PCR and disc diffusion antimicrobial susceptibility tests determined. Logistic regression analysis assessed risk factors for Campylobacter isolation, the level of Campylobacter contamination among positive carcasses and antimicrobial resistance outcomes. Campylobacter spp. were confirmed in 65.4% of neck skin samples and 17.1% of packaging samples. 13.8% of neck skin samples had the highest level of contamination (>1000 cfu/g). Large birds had a significantly higher number of samples with >1000 cfu/g (p<0.001) and as chicken carcass weight increased, birds were more likely to be Campylobacter-positive (p<0.05). A high prevalence of resistance was seen to ciprofloxacin (42.0%) and 38.5% of samples contained at least one multi-drug resistant Campylobacter isolate. This study demonstrates that Halal chicken has a higher Campylobacter prevalence than non-Halal chicken. Interventions should be introduced to reduce this increased public health risk to consumers.

In solving the problem of providing the population with high-grade food, an important role belongs to the domestic poultry processing industry as the most effectively developing in the world. At the same time, the market of delicatessen products from poultry meat is not large and it needs to expand the range. Of particular interest is the development of raw smoked products using starter cultures. A comparative commodity science assessment of the biological usefulness of raw smoked whole- muscle poultry meat product is given. As a result of the commodity quality assessment, it was proved that the types of raw smoked products from poultry meat offered to consumers have the best organoleptic properties and nutritional value. In the future, when calculating the biological value of raw smoked products, data from the amino acid score of experimental and control samples were used.Тhe biological value of meat products primarily depends on the quantitative content of essential amino acids and polyunsaturated fatty acids, the degree of availability of nutrients to digestive enzymes and the level of assimilation in the body. In connection with the above, on certain types of experimental meat products, a series of experiments were consistently presented, the results of which are presented in this article. Key words: poultry meat, starter cultures, amino acid score, raw smoked products.

Listeria monocytogenes and Salmonella are pathogenic bacteria that can contaminate food products during or after processing. Ready-to-eat (RTE) food does not undergo any treatment to ensure its safety before consumption, and therefore risk of foodborne disease must be considered if these pathogens are present in the food. To evaluate the prevalence of these pathogens in RTE food, 140 RTE fish product samples, 501 RTE meat product samples, 462 RTE dairy samples, and 123 RTE dishes and desserts, providing a total of 1,226 samples, were collected from retail stores and food industry and analyzed for the presence of L. monocytogenes. A total of 1,379 samples consisting of 187 RTE fish products and 569 RTE meat products, 484 RTE dairy products, and 139 RTE dishes and desserts were collected and analyzed for the presence of Salmonella. L. monocytogenes was isolated from 20% of frozen Atlantic bonito small pies, 7.9% of smoked salmon samples, 11.1% of the pork luncheon meat samples, 6.2% of frozen chicken croquettes, 16.9% of cured dried sausage samples, 12.5% of cooked ham samples, and 20% of cooked turkey breast samples. L. monocytogenes was also found to be present in 1.3% of fresh salty cheese samples and 15.1% of frozen cannelloni samples. Salmonella was isolated from 1.2% of smoked salmon samples, 1.5% of frozen chicken croquettes, 2% of cooked ham samples, and 11.1% of cured dried sausage samples. Overall, occurrence of these pathogens in RTE foods was similar to that previously reported in the literature.

Background: One of the concerns of consumers of animal protein sources is the residues of heavy metals in meat. The accumulation of these elements in meat and the consumption by humans can cause acute and chronic disorders in the function of vital organs. Methods: For the estimation of cadmium, zinc and silver in the poultry meat products, 100 samples of chicken breasts, thighs, hearts and livers were collected from meat markets in Isfahan Province. The tissues were digested and passed through filter paper, and the cadmium, zinc and silver contents were measured by an atomic absorption spectrophotometer. Results: The mean contents of cadmium in the chicken thigh, breast, liver and heart samples were 0.055±0.021, 0.048±0.023, 0.074±0.031, and 0.012±0.004 mg/kg, respectively. The mean contents of zinc in the chicken thigh, breast, liver and heart samples were 17.19±8.10, 15.70±5.75, 22.10±10.87, and 19.70±10.38 mg/kg, respectively. The concentrations of cadmium and zinc were below the international permissible limits in all samples. The mean concentrations of silver in some chicken thigh, breast, liver and heart samples were 0.0080±0.0044, 0.0048±0.0013, 0.012±0.009 and 0.0036±0.006, respectively. Of note, silver was not detected in most chicken samples. Conclusion: This study did not find cadmium, zinc and silver in the chicken meat samples above the international permissible limits. However, frequent monitoring for heavy metals in poultry meat sold in public markets is warranted to prevent their transmission to the human food chain.

The production of food products with a sufficient amount of functional ingredients is an urgent task for the modern food industry, since the health of every person and nation is largely determined by the diet. An important role in the formation of the range of functional food products is assigned to the development of new recipes and technologies for meat products. In this work, horse meat was used as raw meat. When developing a horse meat product, different methods of heat treatment of the main raw materials were used: the traditional method - frying and stewing, cooking in a combi oven, sous-vide technology. A comparative analysis of heat treatment of meat has been carried out. Investigations were carried out using digital image processing methods to compare the color change of meat samples during cooking by the above methods. The ability to select a fragment of an image for a more detailed study with the output of statistical information about the number of pixels by secondary or tertiary colors has been implemented. The geometric characteristics of objects are determined - area, perimeter, height, width, as well as color characteristics for the selected color components. Using the method of digital image processing, the processes occurring during heat treatment have been established, which makes it possible to regulate and correct the technology of cooking meat products, analyze the geometric and color characteristics of finished products. A program and method for determining the color characteristics of the meat samples under study have been developed.

The most common type of falsification of animal products is the substitution of raw materials of more valuable types with less valuable ones, including poultry meat. This paper presents the results of identification of undeclared chicken DNA in meat products using real-time polymerase chain reaction to detect falsification of products sold in Moscow and the Moscow region. As a result of PCR research, chicken DNA (Gallus gallus) was found in six out of ten samples of meat products, but semi-quantitative analysis excluded one meat product, since the amount of the desired component was less than one percent. All ten samples were also subjected to organoleptic evaluation, physical and chemical studies, luminescent microscopy, and the determination of safety indicators (the number of chemical elements, pesticides, antibiotics, and radionuclides). The results of comprehensive research did not reveal any deviations. Thus, the method of polymerase chain reaction allows you to determine the type of raw materials in the composition of minced meat products, finely ground semi-finished products, including those subjected to heat treatment. To accurately confirm the presence of falsification of meat products detected by PCR-RV, not only qualitative analysis, but also quantitative analysis is necessary.

Product Manufacturing

Production of meat and meat products is one of the key segments of domestic processing industry. In 2018, its share in total food production in Ukraine reached 17.78% (vs. 15.93% in 2013). At the same time, the main problem holding back the development of this segment is the reduction of the raw material base for the industrial processing of meat due to the crisis in animal husbandry, especially in pig and cattle breeding. The purpose of the article is to define the problems and to outline the prospects for the development of meat processing manufacturing in Ukraine, given the current state of the domestic and foreign markets of meat raw materials (chicken, pork, beef, etc.). The meat and meat product manufacturing in Ukraine is dominated by poultry meat, which share has increased by 7.22 pp. in the last six years. Instead, the share of meat products decreased by 6.54 pp. These trends indicate the reduction of advanced processing of meat raw materials. This is largely due to the low level of operating profitability of meat product manufacturing in Ukraine – 2.6% in 2018 vs. 3.7% in 2013, while the profitability of poultry meat manufacturing reached 11.3% (vs. 9.1%). Given the latest global trends in changing consumer preferences in favor of dietary types of meat, this poultry development trend in Ukraine has great prospects, especially in regions where there are no large agricultural companies. In contrast to poultry farming, the trends in domestic pig breeding are mostly negative, due to the decrease in the number of pigs caused by outbreaks of African swine fever. An even more critical situation in Ukraine is with the production of beef and veal, which is a direct result of the cattle livestock population reduction by more than 6 times in the last 25 years, as well as of the high cost of meat procurement. The latter is caused by poor livestock feed base. To overcome this problem, it is necessary to increase the volume of domestic production of compound feeds and their components. In particular, a promising area for the development of meat processing in Ukraine is the production of animal origin feeds, the raw material for which is food waste. Integrated use of meat raw materials will ultimately increase the level of profitability of this segment of the processing industry.
