Resumo
Das principais zoonoses detectadas pelo serviço de inspeção oficial durante o exame post-mortem, a cisticercose e a tuberculose merecem destaque pela importância que possuem para a saúde pública e por gerarem impactos significativos na economia e no rendimento final. O presente estudo teve como objetivo verificar a evolução das ocorrências de cisticercose e de tuberculose durante 21 anos de inspeção post-mortem de bovinos, realizada em um frigorífico do centro-oeste paulista, localizado na cidade de Lins (SIF 337). Os dados coletados foram analisados em software SigmaStat versão 3.5 e, posteriormente, construídos intervalos de 95% de confiança para a proporção de ocorrência e as variáveis resposta também foram submetidas à análise de variância utilizando o procedimento Proc Mixed do software SAS 9.4 TS1M2, teste de Tukey-Kramer com nível de significância de 5%. No decorrer de todo o período, foram abatidos 5.240.138 bovinos. A ocorrência de tuberculose verificada foi de 0,15% (7.741), sendo maior em 1996 (0,41%) e menor em 2015 (0,02%), demonstrando uma redução de 11 vezes. Em relação à cisticercose bovina, foi de 4,34% (227.728), na qual 75% das carcaças continham cisticercos vivos e 25% calcificados, sendo as maiores ocorrências de cisticercose total encontrados em 2000 (6,7%) e as menores em 2015 (2,0%), com redução de 2,13 vezes. Conclui-se que as melhorias nos sistemas produtivos que aconteceram em duas décadas e a eficácia dos programas sanitários e da inspeção realizada nos matadouros frigoríficos contribuíram para a redução da ocorrência de tuberculose e cisticercose bovina ao longo dos anos, conforme observado nos dados obtidos neste estudo.
Among the major zoonoses detected by the official inspection service during the post-mortem examination, cysticercosis and tuberculosis are highlighted because of the importance they have for public health and because they generate significant impacts on the economy and final income. The present study had as objective to verify the evolution of the occurrences of cysticercosis and tuberculosis during 21 years of post-mortem inspection of cattle, carried out in a slaughterhouse in the center-west of São Paulo, located in the city of Lins (SIF 337), through data collected from the activities of the Federal Inspection Service (SIF), analyzed in software SigmaStat version 3.5 and built intervals of 95% confidence for the proportion of occurrence and the response variables were also submitted to analysis of variance using the Proc Mixed procedure of SAS 9.4 TS1M2 software, Tukey-Kramer test with significance level of 5%. During this period, 5,240,138 cattle were slaughtered. The occurrence of tuberculosis was 0.15% (7,741), being higher in 1996 (0.41%) and lower in 2015 (0.02%), showing a reduction of 11 times. In relation to bovine cysticercosis, it was 4.34% (227.728), in which 75% of the carcasses contained live cysticercus and 25% calcified, with the highest occurrences of total cysticercosis found in 2000 (6.7%) and the lowest in 2015 (2.0%), with a reduction of 2.13 times. It is concluded that the improvements in the production systems that occurred in two decades and the effectiveness of the sanitary programs and the inspection carried out in the slaughterhouses contributed to the reduction of the occurrence of tuberculosis and bovine cysticercosis over the years, as observed in the data obtained in this study.
