Prevalence of Sarcocystis infection in processed meat products by using digestion and impression smear methods in Hamedan, Iran

Abstract

Sarcocystis is a common zoonotic parasite which can be transmitted through ingestion of contaminated, undercooked meat and is a major cause of economic loss in many countries. This study aimed to detect Sarcocystis parasite in processed meat products in Hamedan, Iran. A total of 20 samples of hamburger, sausage, and cocktail were collected from markets from three factories in Hamedan, Iran. The samples were examined by digestion and impression smear methods for detecting Sarcocystis parasite. The results showed that 80% of all tested samples were infected with Sarcocystis. The infection rate in hamburger, sausage, and cocktail were 87.5, 83.33, and 66.66%, respectively. The highest infestation rate was observed in hamburger. The present study shows that the rate of Sarcocystis contamination in meat products is very high. So, evaluation of raw meat quality in addition to applying hygienic programs at all stages of the production line is inevitable. Also, consumption of undercooked meat products or fast food should be avoided.
