ABSTRACT
The aim of this study was to identify the prevalence and the main risk factors related to the transmission of bovine cysticercosis based on tracking animals sent for slaughter and coming from properties located in the micro-region of Uberlândia, Minas Gerais, Brazil. The properties were previously evaluated for the occurrence of cysticercosis during post-mortem inspection in the 12 months prior to the beginning of the research, and those with animals with bovine cysticercosis found at least once during this period were considered positive. A cross-sectional study was carried out on 87 properties, from which 1024 bovine serum samples were collected. Indirect ELISA performed serological diagnosis and Immunoblot confirmed positive sera. The prevalence found in this study was 5.1% (95% CI = 3.74-6.42). The risk factors identified were cattle origin (RC = 4.9), grazing (RC = 6.4) and sewage destination on the property (RC = 3.6). These environmental factors suggest that sanitation control measures and the restriction of pastures beyond the property boundary can help prevent disease in the study area. A control system based on risk analysis was discussed and proposed as a strategy to control bovine cysticercosis in the Triângulo Mineiro region and other regions of the country.
