Bovine tuberculosis and associated consequences in the rural commune of Tanghin-Dassouri in Burkina Faso

Tuberculose bovine et conséquences associées

Abstract

Bovine tuberculosis is a major zoonotic disease caused by the bacterium Mycobacterium bovis. It is a disease with
a high hygienic and economic impact. The objective of this study was to assess the prevalence of bovine tuberculosis
through seizures from 2018 to 2020 on the Yimdi slaughter area with the economic consequences and risk
behaviours associated with this zoonotic disease in the rural commune of Tanghin-Dassouri in Burkina Faso. Thus,
a retrospective cohort study was conducted. Economic losses and risk behaviours towards this zoonosis were
determined by a questionnaire. Of the 35,796 cattle slaughtered, 722 lungs were seized, representing a prevalence
of 2.0±0.2% partial TB-related lung seizures. No cattle carcasses were fully seized. Economic losses were estimated
at 2,166,000 FCFA. The most common risk behaviours observed in humans were the sale of unhealthy animal
proteins, the consumption of undercooked meat and offal, and the consumption of unpasteurized raw or curdled milk
and fresh cheese. In the light of these results and in order to improve the safety of foodstuffs of animal origin, this
study should be extended to other slaughterhouses and slaughter areas in Burkina Faso with the effective
involvement of all municipalities in the fight against illegal slaughter. Laboratory confirmation and awarenessraising
of butchers on the risks of zoonotic transmission of tuberculosis are necessary.
