Meat by-products safety indicators analysis by the Omsk region producers

The purpose of the study is to analyze the safety indicators of meat by-products from producers in the Omsk Region. Tasks: determination of sanitary-significant indicators (content of heavy and radioactive metals, microbiological profile, presence of antibiotics and pesticides) and quality indicators (organoleptic and physico-chemical profile) in a sample of meat offal. The object of research is offal of slaughter animals, chilled and frozen (beef); meat by-products, processed, 2nd category - light beef, frozen. The product is produced at a meat processing plant in the Omsk Region and is intended for sale through retail chains in the city of Omsk. The quality of the product is assessed using standard methods. Research (2021) was carried out at the Siberian Cossack Institute of Technology and Management (branch of the Federal State Budgetary Educational Institution of Higher Education (FGBOU HE) Moscow State University of Technology and Management named after K.G. Razumovsky) using the laboratory facilities of the FGBOU HE Omsk State Agrarian University named after P.A. Stolypin with the analysis of the average sample according to the analyzed indicators in threefold analytical repetition. The concentrations of heavy metals that do not exceed the MPC in the tissue of the beef lung were determined. In the test sample, arsenic was found the most, lead was 2.5 times less, and traces of cadmium and mercury, as well as trace amounts of cesium 137 (less than 3 Bq/kg). The content of organochlorine compounds established in the lung tissue (in particular, dichlorodiphenyltrichloromethyl methane and its metabolites) is 2.5 times lower than the maximum allowable concentration (less than 0.004 mg/kg). Negative results were obtained in the analysis of the microbiological profile of the sample and the absence of traces of antibiotics in it. These studies confirm the ecological and nutritional safety of meat by-product light frozen beef and testify to the observance by the producers of the Omsk Region of the sanitary conditions for keeping cattle, as well as the conditions for slaughtering and storing meat offal.
