Cysticercosis in cattle in Senegal.

The hearts of 51, and the masticatory muscles of another 51 cattle from the slaughter-house in Dakar, were examined by careful dissection. Cysticerci and/or cystic lesions were found in 13.7% of the hearts and in 25.5% of the masticatory muscles. The cystic lesions were examined histologically in an attempt to identify Taenia saginata cysticerci. A final infection rate of 5.8% in hearts and 15.7% in masticatory muscles was thus obtained. Lower percentages were recorded after inspecting 2088 slaughtered cattle by the routine meat inspection technique.
