The mean condemnation values showed the presence of hydatidosis in 523,399 (6.97%), cysticercosis in 92,277 (1.23%), and tuberculosis in 10,595 (0.14%) cattle carcasses. The mean values of hydatidosis diagnoses were higher in the regions of Alegrete (14.19%), Bagé (19.62%), and Pelotas (17.71%). The regions of Osório (1.86%), Santa Maria (2.10%), and São Luiz Gonzaga (1.83%) had highest rates of cysticercosis condemnations. All regions maintained an average bovine tuberculosis diagnosis rate of less than 1% and Estrela region had the highest index (0.70%). Results showed that the three diseases occurred in all regions of the state, the average prevalence rates in each region are variable, and distribution seems to be regionalized. This knowledge contributes to the plans for controlling these diseases, which are zoonoses that cause economic losses to the productive sector.
