Shiga toxin-producing E. coli(STEC), also called verotoxinogenic E. coli, usually do not cause disease inanimals but may cause watery diarrhoea, haemorrhagic colitis, and/orhaemolytic uraemic syndrome in humans. Zoonotic STEC include the O157:H7strains and, with increasing frequency, certain non-O157 strains.
