DIAGNOSIS OF LARVEL ECHINOCOCCOSIS IN FARM ANIMALS IN THE TERRITORY OF THE RUSSIAN FEDERATION

Zoonotic invasions are widespread on the territory of the Russian Federation, one of them is echinococcosis. In this regard, the purpose of the study was to study the spread of echinococcosis of farm animals in Russia on the basis of quarterly and annual reports of the 1-vet form for 2020 - 2023, submitted by the Center for Veterinary Medicine, as well as the results of our own research - conducting a veterinary and sanitary examination of carcasses and internal organs of cattle (521) and sheep (899) from four economic regions of the Russian Federation: Central Black Earth, Central, Volga and North Caucasus. Veterinary and sanitary examination of carcasses and internal organs was carried out in accordance with the Technical Regulations of the Customs Union "On the safety of meat of meat products" dated 09.10.2013 No. 68 TR CU 034/2013 and "Veterinary rules for the appointment and conduct of veterinary and sanitary examination of meat and slaughter products ( fishing) of animals intended for processing and (or) sale”, approved on April 28, 2022 by the Ministry of Agriculture of the Russian Federation (Order No. 269). Based on the analysis of the 1-vet form reports, it was found that deer were the most infested: EI = 6,6% in 2020, 7,4% - in 2021, 6,4% - in 2022 and 0,4% - in 2023 During the veterinary and sanitary examination, the authors found that echinococcosis of cattle was diagnosed in the Central region, out of 295 carcasses 6 turned out to be infested, which corresponds to 2,03%, the Central Black Earth and Volga regions are safe, and there are no data on the North Caucasus, Since there were no carcasses and internal organs for research in the Moscow region, the extensiveness of invasion (EI) in Russia was 1,2%. In sheep, the highest percentage of infection with echinococcosis was diagnosed in the Volga region (EI = 41,9%) and the North Caucasian regions (EI = 31,5%), in the Central region a single case of detection of larvocysts in sheep was detected (EI = 0,4%), in Russia EI=23,6%.
