This work aims to characterize the productive chain of beef cattle in the town of Tailândia, Pará, Mesoregion Northeast Pará, in order to identify the state of the art and emphasize the slaughter stage and prevalence of economic losses carcasses of convictions and cattle organs and confirmation by microbiological analysis of lesions suggestive of bovine tuberculosis. For evaluations, secondary data on government and institutional sites, primary data through interviews with producers, cold slaughterhouse owner, community leaders and experts from public entities were used. In second phase, primary data through spreadsheets slaughtering records and convictions of carcasses and viscera were evaluated, from March 2010 to October 2014 and found that bovine tuberculosis was one of the highest conviction pathologies (2.98%) and generating greater economic loss (71.48%). Given these results, we sought confirmation by histopathological analysis and polymerase chain reaction - PCR in order to characterize the lesions and identify the presence of Mycobacterium bovis. The histopathology showed that only 1.96% of the samples corresponded to the inflammatory process characteristic of tuberculosis and 4.25% with amplification profile for the species of M. bovis. The results of this study allow us to conclude that there is need to use complementary methods to improve diagnostic of bovine tuberculosis in slaughterhouses to increase the epidemiological disease control, streamline the inspection service and reduce economic losses generated, which will make the strongest production chain.
