Sarcocystosis is a common disease between humans and livestock that occurs from the consumption of raw or undercooked meat and can be a threat to consumer health. The aim of the present study was to determine the occurrence of microbial and parasitic contamination in hamburgers, ground meat, and kebabs sold in Ahvaz county using PCR and microscopy methods. In this study, 90 samples including 30 ground meat samples, 30 hamburger samples and 30 kebab samples were collected from supply centers and transferred to the Food Hygiene Laboratory of Islamic Azad University, Shahrekord. The samples were used to examine the presence of sarcocysts by microscopy and PCR and to detect Escherichia coli contamination by standard methods. The results showed that respectively sarcocysts were detected microscopically in 7 samples (23.3%) of traditional hamburgers, 5 samples (16.67%) of packaged ground meat, and 7 samples (23.7%) of kebabs. PCR results showed that sarcocysts were detected in 5 samples (16.67%) of hamburgers, 4 samples (13.33%) of ground meat, and 7 samples (23.3%) of kebabs. Also, Escherichia coli contamination was found in 9 samples (30%), 4 samples (6.67%) of traditional hamburgers, kebabs, and ground meat. Given the presence of Escherichia coli and sarcocysts in all samples, it is recommended to avoid eating raw or undercooked meat products, and operators should take strict measures to enforce strict regulations.
