Zoonotic tuberculosis is a major form of TB affecting humans and many animal species. Infected cattle pose a threat to public health. The aim of the study was to characterize the risks of exposure to bovine tuberculosis by slaughterhouse workers in Brazzaville. A survey was carried out among 57 workers from three slaughterhouses in Brazzaville (Mpila, Kanga Mbanzi and La Fougère) using questionnaires and field observations. The results of the profile revealed that the majority of staff are made up mainly of people over 40 years old (40.6 ± 8.4) i.e. 50.9% and 96.5% male. Married workers represent a third of respondents (29.8%) and live in families made up of 4.9 ± 2.4 people. Workers with secondary education are the majority (66.7%). The average number of years of work in slaughterhouses in Brazzaville is 18.9 ± 9.5 years. The survey also showed that many workers, 52.6%, have never received training to work in slaughterhouses. A tier of workers (31.7%) have no knowledge of animal tuberculosis, in particular its modes of transmission or its clinical signs. The premises are; normal, regularly cleaned, but are not disinfected. Despite the common occurrence of injuries, 73.7% of those surveyed said that they were not subjected to medical checks. To this, we must add, the lack of work clothes adapted by some (29.8%). All of these shortcomings constitute significant risks of contamination from zoonoses, and tuberculosis in particular. Thus, the study recommends strengthening the capacities of professionals in slaughterhouses, their medical follow-up and improve infrastructure. Finally, the fight against zoonotic tuberculosis requires a multisectoral framework involving doctors and veterinarians in the context of the "One Health" approach.
