Diagnóstico e fatores de risco do complexo teníase-cisticercose bovina no município de Salinas, Minas Gerais

In order to diagnose the situation of bovine taeniasis-cysticercosis complex in the municipality of Salinas, Minas Gerais, Brazil, blood samples were collected from 355 cattle in 18 randomly selected farms. A socioeconomic questionnaire was filled in each farm for the analysis of factors which favor the maintenance of the taeniasis-cysticercosis complex. An epidemiological survey of human taeniasis was performed through analyses of the Municipal Health Department in the 2007-2010 period. A prevalence of 4.7% for bovine cysticercosis and the frequency of 0.29, 0.36, 0.24 and 0.24% for human taeniasis, during the evaluated period, was found. Among the risk factors, a statistically significant correlation was found between the occurrence of bovine cysticercosis and the ingestion of undercooked meat. It was concluded that bovine cysticercosis is present in the municipality of Salinas, due to inefficient heat treatment of the meat as the main risk factor for maintenance of the taeniasis-cysticercosis complex, reinforcing the need to adopt control measures with continuous epidemiological and health surveillance.
