THE RESULTS OF BAKTERIOLOGICAL RESEARCH AND THE RANGE OF SEROLOGICAL VARIANTS OF SALMONELLA ISOLATED FROM FOOD PRODUCTS OF ANIMAL ORIGIN IN UKRAINE IN 2016-2020

Introduction. The issue of food safety of animal origin is of public concern due to outbreaks of food poisoning, the most common causes of which are the zoonotic pathogen Salmonella spp. The number of known serological variants of Salmonella is constantly growing. Salmonella is a complex and acute challenge of humane and veterinary medicinе, due to the complex antigenic structure of the pathogen. A great threat is posed by rare serovars S. vuadens, S. thompson, S. virchov, S. solindale, S. papuana, S. infantis that have not previously been isolated.

The goal of the work. To analyze the results of bacteriological studies of food products of animal origin produced in Ukraine on Salmonella spp. in 2016-2020, to establish serological variants of isolated salmonella.

Materials and methods. The research was conducted on the basis of the laboratory of microbiological research of food and feed of research bacteriological department of the State Scientific and Research Institute of Laboratory Diagnostics and Veterinary and Sanitary Expertise. The analysis of official statistical reporting data of state laboratories of the State Service of Ukraine for Food Safety and Consumer Protection in 2016-2020 was also performed. All researches were performed by standardized methods according to the current normative documents.

Results of research and discussion. Contamination of food products of animal origin is related not only to the circulation of the pathogen Salmonella spp. among various animals that are a direct source of infection, but also to the compliance with sanitary and hygienic requirements for technological processing of raw materials of animal origin and production. The most contaminated with Salmonella spp. over a 5-year period were poultry by-products– 0.23%, poultry meat – 0.18%, semi-finished meat products – 0.10%, eggs – 0.07%.

The most common serovars of Salmonella isolated from food products of animal origin in 2016-2020 were: S. enteritidis – 18.3%, S. infantis – 3.8%, S. typhymurium – 3.4%, S. virchov, S. thompson, S. vuadens – by 2.4% each, S. isangi, S. papuana, S. enterica, S.colindale – by 0.5% each.

Conclusion and prospects further research. Salmonellosis remains a relevant foodborne illness in Ukraine. The most contaminated with salmonellosis are poultry meat (0.18%), semi-finished products (0.10%), poultry offal (0.23%) and eggs (0.07%). The safest products concerning salmonellosis were meat, canned meat and heat-treated meat products, milk and dairy products, fish and fish products.

Keywords: bacteriological research, serological variants of Salmonella, regulatory documents, food products of animal origin, Salmonella spp.
