An abattoir based Cross-Sectional Study on Prevalence and Economic Impacts of Liver Hydatidosis in Slaughtered Animals, Garmsar, NorthEast Iran

One-year cross-sectional study from, April 2015 to April 2016, was conducted at the Garmsar slaughter house, Northeast Iran, to determine prevalence rate and assess economic loss due to hepatic hydatidosis. Routine and daily postslaughter inspection of a total 13620 animals including sheep (9272), goats (8280), and cattle (1068) was carried out. Two hundered and twentyeight livers of slaughtered animals were infected with hydatidosis forming a prevalence of 1.67 %. The mean prevalence showed 1.5%, 1.7%, and 3%, for sheep (140), goats (56) and cattle (32) respectively. The economic loss due to condemnation of 228 livers of cattle, sheep and goats using retail market price during the study period amounted to 221000000 Iranian Rials (IRs) equivalent to US$ 6260.61 (One American dollar = 35300IRs). In conclusion, the presence of hydatidosis at a such prevalence and the consequent effect on ruminants signify the need for the control of stray dog population, deworming of dogs, and avoidance of backyard slaughter and proper disposal of infected viscera to curtail the problem in Garmsar. Development of socio-economic and cultural conditions of community based-control strategies is imperative. Key stakeholders are urged to prevent the access of dogs to fresh offal and to impose hygienic disposal of condemned organs. Further studies are needed to determine genotypic characteristics of Echinococcus granulosus local strains in livestock, assess the indirect economic loss and investigate public health implication of hydatidosis in Garmsar district.
