Raw milk cheese is considered as a risk for foodborne Shiga toxin-producing E. coli (STEC) contamination. In this study, 124 raw milk cheese samples (64 Kareish and 60 Damietta cheese samples) were assayed for the presence of STEC using molecular detection of virulence markers such as Shiga toxins (stx1 and st×2) and intimin gene (eae) and by serotyping. By PCR, 14 E. coli strains showed the presence of the stx2 gene, either single or in association with the stx1, and were considered positive… CONTINUE READING
