Abstract: Research aimed to determine the optimal doses of gamma radiation required for sterilisation of agricultural products from biological factors of microbial and fungal nature. To achieve this goal, doses of 5.0, 7.5, 15.0, 22.5, 30.0, 45.0, 60.0, 75.0, 90.0 kGy were tested at the “Issledovatel” gamma installation to sterilize minced meat from microbes; for sterilization of grain from toxic fungi – doses of 7.5, 15.0, 20.0, 22.5, 25.0, 30.0, 35.0, 40.0, 45.0, 60.0 kGy. The dose rate absorbed by the product in all variants was 0.594 Gy/s. When irradiating minced meat infected with E. coli strain KV-1 and strain PL-6, a complete absence of microbial growth was observed at a gamma irradiation dose of 20 kGy, with spores of Cl. perfringens strain No. 28 (type A) – at a dose of 25 kGy, with one-day culture (vegetative form) Cl. perfringens strain No. 28 (type A) – 15 kGy. Complete sterilisation of grain infected with toxigenic fungi Aspergillus flavus occurred at a dose of 45.0 kGy, Aspergillus – 35.0 kGy, Fusarium sporotrichiella – 22.5 kGy, Helminthosporium – 20.0 kGy, Alternaria alternata – 15.0 kGy. Meat irradiated at a dose of 25 kGy, in terms of organoleptic, physicochemical, bacteriological indicators, as well as biological usefulness (based on the results of daily feeding to rat pups), complied with the requirements of state standards of the Russian Federation, the rules of veterinary examination of slaughter animals and veterinary and sanitary examination of meat and meat products to a good quality product. The study of the general toxicity and biological usefulness of grain (based on the results of daily feeding to rat pups) indicated the non-toxicity and biological usefulness of grain irradiated at doses of 25, 35 kGy and the toxicity of irradiated at a dose of 45 kGy.
