Parasites of the genus Sarcocyst are among the most common parasites found in domestic ruminants, and some of them can cause significant economic losses when causing clinical and subclinical diseases. The purpose of this study was to investigate the level of sarcocyst contamination using microscopic, macroscopic and PCR methods in slaughtered animals in Isfahan slaughterhouse. In this research, 335 carcasses including 130 sheep carcasses, 95 goat carcasses and 110 cow carcasses were evaluated for contamination. The evaluated tissues included tongue, esophagus, heart and diaphragm. The results showed that out of 335 samples of slaughtered animal carcasses, 18 samples (5.37%) were diagnosed as sarcocysts in the macroscopic method, 46 samples (13.73%) in the microscopic method, and 74 samples (22.08%) in the PCR method. The results showed that 62 sheep carcasses (47.62%), 28 cattle carcasses (28.18%), and 45 goat carcasses (47.36%) were infected with sarcocyst. The highest frequency of sarcocyst in the sheep sample is in the esophagus (53.22%) and the lowest in the heart and diaphragm (9.67%), respectively, for the cow, the highest frequency of sarcocyst is in the tongue (48.14%) and the lowest in the diaphragm (9.87%) and for goats, the highest frequency of sarcocysts was in the esophagus (31.11%) and the lowest frequency was in the diaphragm (15.56%). Considering the frequency of sarcocyst infection in the carcasses of slaughtered animals, it is recommended not to consume meat and meat products in raw and semi-cooked form, and also to avoid keeping cyst carriers in the environment of keeping animals.
