Microbiology of the food chain — Detection, isolation and characterization of Shiga toxin-producing Escherichia coli (STEC) — Part 1: Horizontal method for the detection and isolation of Shiga toxin-producing Escherichia coli (STEC)

Scope

This standard describes the detection and isolation of Shiga toxin-producing Escherichia coli (STEC). The procedure includes the detection by Real Time PCR of the major virulence genes of STEC, stx1 and stx2 (Reference [2]) in enrichment cultures. Isolation of STEC from the enrichment culture is attempted if one or both stx genes are detected in the screening.
