Abstract

The purpose of research is to study the results of post-mortem examination of beef, to monitor parasitic diseases among the population of the Kabardino-Balkarian Republic. The material for the study was the data obtained from post-mortem examinations from 2020 to 2022 and information from the Center for Hygiene and Epidemiology of the Office of the Federal Service for Surveillance on Consumer Rights Protection and Human Welfare in the Kabardino-Balkarian Republic for the same period. Recently, a significant part of productive animals in the territory of the Kabardino-Balkarian Republic comes from the southern regions of the Russian Federation. Based on the results of reports conducted by the veterinary service for the period 2020–2022. 7,427 cattle carcasses were identified with affected organs and tissues by the following invasive diseases: Fasciolosis, Echinococcosis, Dicrocoeliasis. In 2020, the highest infection rate was due to Echinococcus granulosus infestation – 42.54 %, followed by Fasciola hepatica and Fasciola gigantica – 32.52 %; the smallest – when infected with Dicrocoelium lanceatum – 24.94 %. In 2021, the highest level of infection was also due to infection by Echinococcus granulosus – 39.02 %, then Fasciola hepatica and Fasciola gigantica – 36.72 %, the lowest was due to infection by Dicrocoelium lanceatum – 24.24 %. In 2022, most of the culling occurred due to infestation: Echinococcus granulosus – 38.50 %, then Fasciola hepatica and Fasciola gigantica – 36.80 %, the least due to infection with Dicrocoelium lanceatum – 24.68 %. Favorable natural and climatic conditions, pasture animal husbandry, and peculiarities of the social structure of the population of the Kabardino-Balkarian Republic lead to the interaction of the pathogen and host populations. Based on the results of epidemiological examinations of foci of invasive diseases of the population in the Russian Federation, the following results were obtained: over the past 5 years (2017–2021), 1,909 cases of infection with Echinococcus granulosus were identified. In total, 551 cases of infection with Echinococcus granulosus and Echinococcus multilocularis were registered in the Russian Federation in 2022.
