In Ilha Grande, located on the coast of Piauí, four cows were diagnosed with bovine tuberculosis, which prompted action by the state's agricultural defense agency, Adapi. The diagnosis led to the compulsory sanitary slaughter of these animals, in line with legislation directed at controlling the spread of this disease among livestock. This case is part of a broader statewide survey conducted by Adapi, which tested 2,700 female cows across 330 farms in 224 municipalities of Piauí.

The slaughtered cows were confirmed to be over 24 months old, a typical age for heightened risk of bovine tuberculosis. Adapi emphasized the necessity for producers to conduct regular testing of their herds and to promptly report any suspected cases to agricultural defense authorities. This proactive approach is crucial for maintaining the health and safety of both livestock and the public, especially considering the serious zoonotic implications associated with infected meat.

Bovine tuberculosis is an incurable zoonosis caused by the bacterium Mycobacterium bovis, leading to severe lesions in infected animals. The disease poses significant risks not only to cattle but also to humans who may consume contaminated meat or come into close contact with affected animals. By enforcing strict sanitary measures, authorities aim to prevent potential outbreaks and protect both agricultural and public health in the region.
