The prevalences of parasitic infections responsible for the condemnation of liver during meat inspection, and their economic implication were estimated in slaughtered animals in Iran. The liver organ was examined for the presence of parasitic lesions during meat inspection in cattle, camel, buffalo, sheep and goat. The parasitic agents observed in the condemned livers of these animals were Fasciola spp., Dicrocoelium dendriticum, Cysticercus tenuicollis and hydatid cyst. The average percentages of liver condemnation for three years period by Fasciola spp., D. dendriticum, Cysticerci and hydatid cyst were 2.12, 2.71, 0.04, and 2.88 %, respectively. The mean prevalence of Fasciola spp. in cattle, sheep, goat, camel and buffalo was 4.32, 1.85, 1.56, 1.31 and 9.31 %, respectively and the mean prevalence of D. dendriticum in those animals were 3.65, 2.66, 2.19, 5.09 and 3.90 %, respectively. Also, the mean prevalence of Cysticerci and hydatid cyst were 0.13 and 3.72 % in cattle, 0.04 and 2.85 % in sheep, 0.05 and 2.40 % in goat, 0.02 and 8.22 % in camel and 0.001 and 5.48 % in buffalo, respectively. The most contributing parasites to marketable liver condemnation were hydatid cyst in sheep, goat and camel and Fasciola spp. in cattle and buffalo, and the average annual cost for condemned livers was 8.2 million USD.
