Abstract

Shiga toxin-producing Escherichia coli (STEC) are important food borne pathogens that can cause severe disease in children by producing two toxins (Stx1 and Stx2). This bacteria harbor several additional virulence factorsand have been classified in different serotypes that have been used as screening for detection of STEC. Aa is not possible to define when a STEC strain is pathogenic, it is important incorporate the risk assessment.
