Cisticercose bovina: dados epidemiológicos da região nordeste do Rio Grande do Sul e material educativo

Abstract

Cysticercosis is a disease that have cattle as the intermediate hosts of Taenia saginata. This parasitic disease is responsible for losses of large financial sums in the meat production chain. Due to the fact that it is a zoonosis, both veterinary and human medicine are involved in the prevention and treatment of the disease. Thus, the objective of this study was to analyze the situation of bovine cysticercosis in the Northeast region of Rio Grande do Sul, in addition to carrying out a survey on the profile of fiscal veterinarians who work in the region and producing an educational material. From June to July 2020, a questionnaire was applied to tax Veterinarians on sanitary inspection and the taeniasis-cysticercosis complex to assess their knowledge on the subject. Data for the years 2015 to 2019 were collected and statistically analyzed from cattle sent for slaughter from the municipalities of Serra Gaúcha and Campos de Cima da Serra, data from cattle slaughtered in regional slaughterhouses and the sites of insertion of the parasite in the carcass. As a way of promoting knowledge about the disease, educational material was produced. The epidemiological survey resulted in an occurrence of 1,10% of cysticercosis in slaughtered cattle from the municipalities of the two regions studied. In regional refrigeration plants, the observed occurrence was 0,95%. The observation of cysticerci in the sites was 68.8% in the heart, 17.6% in the head, 5.9% in the liver, 2.7% in the carcass, 2.5% in the diaphragm, 2.2% in the tongue and 0.03% in the esophagus. The information obtained through the study shows that cysticercosis is present in the region in expressive values, which demands sanitary education measures for humans, management directed to cattle and rigorous inspection of carcasses, thus causing the incidence of the disease to be really reduced.
