Abstract

Sarcocystis is composed of 130 species of heteroxenous coccidian and differ in terms of life cycle and pathogenicity. This parasite is common between humans and livestock and human being infected by eating raw or semi-ruminating meat. The infection is a global outbreak, causing many diseases in many animals and causing many health and economic losses. The aim of this study was to determine the rate of contamination of sarcosystis in slaughtered livestock in Semnan abattoir using compression and digestion methods. Hence during the winter of 1396 and spring of 1397, 334 cattle and 334 sheep and goats (evenly sheep and goats) were randomly selected at abattoir and examined by digestive and compression methods for the presence of Sarcocystis cyst. The mean of contamination of Semnan in cattle was determined using digestive method of 87% and with compressive method of 60%, in goats by digestive method 83.33% and using compressive method 59% and in sheep by digestive method 81% and with the compressive method was 59.52%. The results showed that the digestive method was the most sensitive method for detecting sarcocystis in abattoir in Semnan. Regarding the high prevalence of sarcosysts, the complete cooking of meat it should be considered, regardless of the apparent inspection outcome.
