Colonization of the human and animal intestinal tract with potential pathogenic bacteria is correlated with the risk of contamination of food products. The current study analyzed the prevalence of and O157H7 in ground meat in Ilam, Iran. Both index organisms were identified following standard food microbiological methods. For , the susceptibility to vancomycin was tested, and PCR was used to check for the gene. was present in all 24 ground meat samples, with no O157H7 detected in samples. The analysis showed the presence of the gene in 5/24 vancomycin resistant enterococci. In conclusion, this study for the first time demonstrates the presence of vancomycin-resistant enterococci in ground meat in Iran. This observation warrants further epidemiologic investigation and should be followed up in the future.
