A cross-sectional study was conducted from November 2018 to April 2019 on cattle slaughtered at Hawassa Municipal Abattoir. The objectives of the study were to estimate the prevalence of Bovine Hydatidosis, characterize the cysts, and estimate direct financial loss associated with condemnation of organs due to Bovine Hydatidosis. A total of 400 animals were selected systematically and subjected to both antemortem and postmortem examinations including by visualization, palpation and incision of organs such as lung, liver, spleen, kidney, and heart. Of the total 400 animals examined, 145 (36.3%) were found to be infected by one or more hydatid cysts. Statistically significant variation was seen in distribution of Hydatidosis among animals with different body condition scores (χ2 =9.135 and P-value = 0.010). Highest distribution of Hydatidosis was recorded in animals with poor body condition score (59.4%) followed by animals with medium (38.3%) and good body condition scores (32.6%). One or more organs per animal were found to be infested and totally condemned: 30% (120/400) lungs, 12.5% (50/400) livers, 5.5% (22/400) spleens, 1.8% (7/400) kidneys and 0.8% (3/400) hearts were infested with the cysts and subjected to a total condemnation. About 282 cysts were collected for characterization, and the laboratory examination revealed that 94 (33.3%) fertile, 143 (50.71%) sterile, 45 (15.96%) were found calcified. Based on size, 99 (35.11%), 124(43.97%), and 59 (20.92%) cysts were large, medium, and small, respectively. From the fertile cysts subjected to viability test 43 (12.25%) were viable whereas 51 (18.1%) were non-viable. In the current study, a total direct financial loss of 293,595.00 ETB per year was estimated resulting from Bovine Hydatidosis in the cattle slaughtered at Hawassa municipal abattoir. This study revealed that Hydatidosis has high prevalence and has led to significant direct financial loss due to condemnation of organs. Therefore, emphasis should be given to the control and prevention of the disease.
