A cross-sectional study was conducted from October 2010 to August 2012 to determine the prevalence of camel hydatidosis and associated risk factors in camels slaughtered for human consumption at Akaki municipal abattoir. The results of this study revealed that out of 770 camels slaughtered, 474 (61.6 %) were harboring hydatid cysts with varying numbers and sizes in different organs (3850) in the following manner; liver (53.51%), lungs (40.39%), heart (0.13%), gastrointestinal track (GIT, 0.9%) and Kidneys (0.13%). The positive samples were put in plastic bags and taken to the laboratory for characterization of the cysts for fertility and viability. There was no significant variation between camels of different origins and the anatomo-morphological features of the cysts. The infection rates varied significantly among age groups (p<0.05), sex (p<0.005) and body condition score (p<0.05) of camels. The prevalence was found to be high (61.94%) in higher age group animals, that is, greater than 10 years as compared to 3 to 5 years (25%). The mean intensity of hydatid cyst among affected camels was found to be 3.1±5.8. Out of the examined cysts, 41.5% were found to be fertile and viable, while 18.3, 21.3 and 18.9% were non-viable, sterile and calcified cysts, respectively. The fertility of the cysts was 68.5 and 70.7% in liver and lungs, respectively.The high prevalence of camel hydatidosis affecting different organs indicates the seriousness of this disease particularly in the area of the origin of these animals that require an immediate control intervention.
