Prevalence, risk factors, and distribution of Cysticercus tenuicollis in visceral organs of slaughtered sheep and goats in central Ethiopia

An abattoir survey was conducted to determine the prevalence of Cysticercus tenuicollis, to find out the association between prevalence and potential risk factors as well as to assess the distribution of C. tenuicollis in visceral organs of slaughtered sheep and goats. Out of the total 768 goats and 630 sheep visceral organs inspected, C. tenuicollis was found in 358 goats (46.6%) and 252 sheep (40.0%), respectively. Adult goats (51.8%) and sheep (47.4%) were more infected than kids (41.4%) and lambs (35.8%), respectively. Goats (58.1%) and sheep (46.5%) from highland areas were more infected than goats (35.2%) and sheep (33.8%) from lowland areas. C. tenuicollis was more frequently detected in the omentum of goats and sheep than any other visceral organs. Appropriate control measures need to be introduced to reduce the prevalence of these parasites in small ruminants.
