Abstract
A cross-sectional study was carried out from November 2015 to March 2016 on a total of 384 sheep slaughtered at Jimma municipal abattoir to determine the prevalence and estimate direct financial loss due to Cysticercus tenuicollis. Ante-mortem examinations and post-mortem organ inspections were performed following standard procedures. A total of 205 animals were found positive for Cysticercus tenuicollis with an overall prevalence of 53.4% (95% CI = 48.0-58.0) with a significant difference (p=0.000) between age groups which was higher in adult animals than in younger age groups. The relative cyst distribution in visceral organs was higher in omentum (38.0%) followed by liver (25.5%) with an estimated financial loss of 21528 ETB from liver condemnation. This study revealed that the occurrence of high prevalence of Cysticercus tenuicollis in sheep slaughtered at Jimma abattoir with a significant financial loss which deserve proper disposal of affected organs and implementation of parasite control programs in the area.

Highlights
Ethiopia is the second in Africa, and the sixth in the world, in terms of sheep population
The prevalence of C. tenuicollis was significantly higher in adult sheep than in the young age group
In this study different visceral organs were affected with C. tenuicollis in which a single or multiple organs were involved
Summary
Ethiopia is the second in Africa, and the sixth in the world, in terms of sheep population. Like many other African countries, it is known that liver fluke, Hydatid cyst and Cysticercus teniucollis are major parasites responsible for low productivity in Ethiopia livestock industry due to imposing poor weight gains and condemnation of organs and carcass of sheep and goats (Abebe, 1995). Infections with the larval stage of some species of Taenia are of veterinary importance, because they cause economic losses due to condemnation of infected offal or meat (Radfar et al, 2005), From this taenia species, Cysticercus tenuicollis is the most important parasite of sheep and goats (Yehualashet et al, 2012), which causes organ condemnation from slaughter houses (Radostits et al, 2007). The oncospheres may remain in the liver or migrate to different part of the body and the cysts are most commonly found attached to the omentums, mesenteries, liver and peritoneum (Radostits et al, 2007)
