Apparent prevalence and performance of post-mortem inspection for bovine tuberculosis surveillance at Korhogo municipal slaughterhouse (northern Côte d'Ivoire)
Abstract
The aim of this study was to determine the apparent prevalence and evaluate the effectiveness of post-mortem tuberculosis diagnosis at the Korhogo slaughterhouse. To this end, 600 bovine carcasses underwent post-mortem inspection. A prescapular lymph node was removed from each carcass, and any lesions suspected of being tuberculous were examined. These samples were then subjected to the Ziehl-Neelsen (ZN) staining test. Following the analyses, the apparent prevalence of tuberculosis was estimated at 2.7%, and the lungs (62.5%) were the most frequently identified organs suspected of having tuberculosis. Furthermore, this test revealed that the sanitary inspection carried out at the Korhogo slaughterhouse had a sensitivity of 5.56% and a specificity of 98.57%, respectively. However, the diagnostic efficiency was only 0.70, a moderate level of performance. This preliminary study highlighted the moderate effectiveness of sanitary inspection in the post-mortem diagnosis of tuberculosis and the need to strengthen sanitary control in this slaughterhouse.
