Products, that meet the requirements of Technical regulations of the Customs Union are possible to produce only from high-quality and safe raw materials of animal origin. However, it is necessary to identify the risks associated with its use, assessment and indication of management mechanisms. In the production of meat products, the mechanisms for managing the identified risks associated with meat raw materials will be different. The aim of our study is to identify the most important risk factors associated with meat from different species of animals, including poultry, currently used in meat processing plants. The emphasis was placed on the meat intended for the production of smoked sausages, as these products are subjected to minimal temperature effects, respectively, under adverse conditions, almost always retains the original parameters of the feedstock (for example, the presence of antibiotics, pathogens). The screening microbiological method for the presence of antimicrobial chemotherapeutic agents was used to identify the chemical risk factor. Classical microbiological methods were used to determine the biological risk factor. It was found that the chemical risk factor (the presence of antimicrobial chemotherapeutic agents) creates a biological problem, i.e. the emergence of antibiotic-resistant strains of pathogens. Thus, in the study of beef, we found that the percentage of samples contaminated with antimicrobial chemotherapeutic agents was 26.7 %, pork –35.3 %, and poultry meat — 42.9 %. At the same time, Salmonella spp. was absent in the same beef samples and the monocytogenes, however, have been found and they have demonstrated their resistance to antibiotics. In pork and poultry all bacteria were found. Perhaps, these species of animals and poultry, strains of microorganisms have the greatest antibacterial resistance.
