Prevalence and Associated Risk Factors of Cysticercosis bovis in Bishoftu Municipal Abattoir, Central Ethiopia

Abstract

Background: Cysticercus bovis has zoonotic implications with economic losses from organ contamination and treatment costs. In developing countries such as Ethiopia, where hygienic standards are low and residents customarily eat raw or undercooked meat, the disease is prevalent. Methods: A cross-sectional study was carried out from December 2021 to June 2022 to determine the prevalence of Cysticercus bovis in cattle slaughtered at the Bishoftu municipal abattoir, in central Ethiopia. Study populations for the active abattoir survey were cattle presented to the abattoir for slaughtering and routine meat inspection conditions. The organ namely the tongue, masseter muscle, liver, and triceps muscle were inspected for the presence of C. bovis. Results: From a total of 330 cattle, 14 were found to be positive for C. bovis, with an overall prevalence of 4.24%. Based on the origin of the animals, the highest prevalence was recorded at Adama (7.27%), followed by Bishoftu (5.45%), Mojo (5.45%), Borana (3.63%), Dukem (3.63%), and Kaliti (0.00%). Similarly, out of 111 adults and 219 old-aged cattle slaughtered and examined at the abattoir, 4.5%, and 4.11% were positive for C. bovis, respectively. Among tested independent variables, sex, body condition score, age, and origin of animals had no relationships with the prevalence of C. bovis. From the detected organ, the tongue ranks first for the highest number of cysts, followed by the masseter muscle, liver, and triceps muscle, with total cysts of 6, 4, 3, and 1, respectively. Conclusion: C. bovis is a prevalent zoonotic parasite disease that causes carcass condemnation; an enhanced understanding of the health consequences of teniasis is required to protect the community.
