Abstract

Beef is a very present meat in the Brazilian population diet, with an annual per capita consumption estimated at 40 kg. The state of Rio Grande do Sul, located in southern Brazil, has a strong livestock with a herd of approximately 14 million cattle, and has in beef cattle one of the foundations of its economy. It is known that beef meat is a food with potential for zoonosis transmission if it is not going through a proper hygienic-sanitary control at slaughter and, if is consumed raw or undercooked. In addition, infected animals remain agents of diseases in the environment by promoting continuity of infectious cycles and endangering human health. The objective of this study was to conduct an epidemiological study on the occurrence of cysticercosis, hydatid disease and tuberculosis in animal slaughtered under sanitary inspection of the Coordination of Animal Products Inspection - CISPOA of Rio Grande do Sul state, betwen 2009 and 2014. Data were obtained from the Department of Agriculture, Livestock and Agribusiness (SEAPA) from Rio Grande do Sul state. The study examined the occurrence of lesions according to the county of origin of carcasses, with the data being presented according to the micro-regions established by SEAPA. A total of 4,460,880 cattle were slaughtered under inspection of CISPOA. We found 51,877 instances of cysticercosis with an average rate of 1.16%. The lowest average levels over the period were recorded in Santa Rosa (0.58%) and Soledade (0.60%). The regional Osorio presented the highest frequency of occurrence, reaching 4.21% in 2009 and only keep occurring average higher than 2% in the six years evaluated. Lesions suggestive of bovine tuberculosis were found in 7,045 carcasses, an average frequency of 0.16%. All regions studied have maintained an average of tuberculosis suggestive lesions below 1% in the six years studied, the regional Estrela had the highest rate 0.86%. Hydatidosis had the highest occurrence rates with 345,727 occurrences and average of 7.75%, highlighting the regional Bage with 22.18% and 19.01% in Pelotas, with endemic status to the disease. Knowledge of these data could assist in drawing up plans to prevent and eradicate these diseases which cause morbidity in humans and animals, as well as considerable economic losses due to the disposal of products.
