Introduction & Objectives: Zoonotic parasites are large groups of zoonoses among which the most important are hydatid cyst, liver trematodes and sarcocystis.These zoonoses are of considerable importance regarding both human health and economy. The objective of this study was to determine the prevalence of tissue zoonotic parasites and their epidemiologic status in Hamadan and to estimate the health and medical burden they impose on the society.

Materials & Methods: In this cross sectional study, viscera (including liver, lung, kidney, heart,…) and muscles of 2590 sheep, 420 cattle, and 490 goats were macroscopically inspected for hydatid cysts, liver flukes, cysticercus , and microscopically (for Sarcocystis) in the Hamadan abattoir. The data were presented by descriptive tables and analyzed by c2 statistical test.

Results: The infection rate for hydatid cyst, Fasciola, Dicrocoelium and Sarcocystis were found 12.3%, 4.9%, 6.5%, and 5.5% respectively. The high infection rates for hydatid cyst and Fasciola were found in cattle (16.2% and 9.5%) and for Dicrocoelium and Sarcocystis were found in sheep (6.9%). Infection rate of lungs was higher (41.2%) than liver (36.6%) and liver and lung simultaneously were 22.2% in the infected animals. Infection to Sarcocystis and Cysticercus were not found in the cattle.

Conclusion: This study indicated that infection rate of tissue zoonotic parasites are relatively high in the domestic animals of Hamadan , however, the rate is lower in comparison to the previous studies. These parasites had imposed considerable economic burden on the society through reduction in the dairy production and increased the risk of infection in the population as well.
