FEATURES OF POSTMORTEM DIAGNOSIS OF CYSTICERCOSIS IN LIVESTOCK ANIMALS AT ENTERPRISES OF VARIOUS TYPES

Abstract

The article highlights some features of the long-term dynamics of infection of livestock animals with cysticercosis. Significant differences are shown in the detection of cysticercosis in pigs and cattle in postmortem diagnostics at enterprises of various types. An analysis of the epizootic situation on cysticercosis of livestock animals was carried out using materials from the veterinary and sanitary examination of raw materials and products of animal origin (Form 5-vet) for 2009–2020. The infection of animals with Cysticercus cellulosaе and Cysticercus bovis was assessed using the conventional method. It was established that the Novosibirsk Region was contaminated with cysticercosis of livestock animals. Finnosis of cattle is recorded annually with infection rate varying from 0.09 to 0.01%, however, cysticercosis of pigs has been detected since 2018. The average cysticercosis infection rate in cattle and pigs was 0.03 and 0.005%, respectively. The leading role in the postmortem diagnostics of finnosis in cattle belongs to meat processing plants. During the research period at meat processing plants, slaughterhouses and markets, 814, 59 and 93 cases of finnosis in cattle were identified respectively, which was 84.0, 6.0 and 10.0%. Cysticercosis of pigs is more often recorded at slaughterhouses (53.0%) and markets (47.0% of carcasses).
