Abstract
A retrospective study was carried out from 2008 to 2013 to estimate the prevalence of hydatidosis in ruminants slaughtered at the Kermanshah municipal abattoir in western Iran A total number of 663633 livestock 393585 sheep 81080 goats and 188968 cattle slaughtered in the 5year period and overall 9524 143 livers and 13147 198 lungs were condemned The lungs were more frequently infected with hydatid cysts than the livers in all animal species The average prevalence of hydatidosis was 27 in this area The prevalence of Echinococcus granulosus infection recorded in the present study was generally lower than those reported from other regions of Iran Greater awareness among farmers destruction of organs containing hydatid cysts prevention of access of dogs to raw offals and implementation of national rabies control program could be responsible factors The results showed a significant difference p 0001 in the prevalence of hydatidosis among studied animals with higher prevalence in cattle than sheep with the lowest prevalence recorded in goats However the annual prevalence of liver and lung condemnations due to hydatidosis was decreased in some years but the overall trend had a variable pattern in the prevalence of hydatidosis over the study period Data showed a significant seasonal pattern for hydatidosis in all studied animals Liver and lung condemnations due to hydatidosis were higher in the fall for sheep and cattle whereas in goats were higher in summer This could be attributed to various factors such as sources of slaughtered animals changes in management practice and ecological factors The current results suggest that a systematic investigation that lead to a disease control strategy is required to reduce the economic and public health consequences of hydatidosis In addition the present survey provides baseline data for the future monitoring of this potentially important parasitic disease in the region
