A cross-sectional survey of bovine hydatidosis was carried out on local zebu cattle slaughtered at Birre-Sheleko and Dangila Abattoirs from August 2007 to July 2008 to determine the prevalence and to estimate financial loss caused by the disease. Postmortem examination, hydatid cyst characterization and direct and indirect financial loss estimations were conducted. Out of the total of 521 animals examined (255 Birre-Sheleko and 266 Dangila), 79 (15.2%) were found harbouring one or more hydatid cyst. The prevalence of the disease between the two abattoirs was not significantly different (P > 0.05). The result obtained from postmortem examination indicated that a total of 112 visceral organs were found harbouring one or more hydatid cysts. The involvement of lung, liver, spleen and kidney was found to be 70.5%, 21.4%, 6.3% and 1.8% respectively. From the total of 224 cysts counted, 147 (65.6%), 29 (12.9%), 3 (1.3%) and 45 (20.1%) were small, medium, large and calcified cysts respectively, and 114 (50.9%) and 65 (29%) were sterile and fertile cysts respectively. Viability rate of 47.7%, all from the lungs, and higher liver calcification rate were observed. The annual financial loss from organ condemnation and carcass weight loss due to bovine hydatidosis at Birre-Sheleko and Dangila abattoirs were estimated to be $18911.6. © 2009 Blackwell Verlag GmbH.
