Situação epidemiológica das zoonoses parasitárias em bovinos: hidatidose, fasciolose e cisticercose no município de Pelotas – Rio Grande do Sul, Brasil

Abstract

Cattle farming is an activity of economic importance for the state of Rio Grande do Sul, Brazil. Meat production in Brazil demonstrates progress and progressive strengthening of the chain over the years. The main objective of the sanitary inspection of slaughter products is to declare that the carcass obtained is suitable or not for human consumption, ensuring the health of consumers, avoiding the transmission of numerous diseases, as well as parasitic zoonoses. Hydatid disease and cysticercosis are zoonoses caused by tapeworms, respectively, Echinococcus granulosus and Taenia spp. Fascioliasis is a parasitic zoonosis caused by the trematode Fasciola hepatica. A retrospective analysis was performed based on information from the Pelotas Municipal Inspection Service (SIM-Pelotas), from 2020 to 2022, to research data on hydatid disease, cysticercosis and fascioliasis in cattle slaughtered under municipal supervision. The overall prevalence of zoonoses was calculated, with the prevalence of fascioliasis 4.62%, hydatid disease 3.31% and cysticercosis 1.20%. This work brings important information about the situation of parasitic zoonoses in the southern region of Rio Grande do Sul during three years of inspection by the municipal inspection service.
