Major Metacestodes Of Sheep And Goats Slaughtered At Three Selected Export Abattoirs In Central Oromia Prevalence Cyst Characterization Assessment Of Financial Losses And Public Awareness About Metacestodes And Their Risk Fac

In small ruminants metacestodes are important as a main cause of organs and meat condemnation contributing to a significant financial loss and they cause human diseases, especially in poor and developing countries. A cross sectional study was conducted between November 2018 and March 2019 with the aim of determining the prevalence, organ distribution, fertility rate, cyst burden and assessing financial losses and public awareness of metacestodes in sheep and goats slaughtered at selected export abattoirs in central Oromia. Routine ante-mortem and post-mortem examination were conducted for the presence of metacestodes. Post-mortem examination was conducted through visual inspection, palpation and systemic incision of each visceral organ particularly the lungs, kidneys, liver, spleen, heart, omentum, mesentery, and striated muscles. In this study, Cysticercus ovis, Cysticercus tenuicollis and hydatid cyst in small ruminants slaughtered at Bishoftu Abyssinia, Elfora and Modjo Allana abattoirs were detected with the overall prevalence of 29.2 % (224/768). Of 384 goats examined, 8 (2.1%), 44 (11.5%) and 33 (8.6%) were found to be infected with C. ovis, C. tenuicollis and hydatid cysts, respectively with over all prevalence of 85 (22.1%). Similarly a total prevalence of 139 (36.2%), 22 (5.7%), 64 (16.7%) and 53 (13.8%) were detected in 384 sheep carcass examined with similar pattern of metacestodes species. Statistically significant variation of infection rate was seen between body condition and agro ecology of animals (P
