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.
Most strains of E.coli are harmless, but those that produce verocytotoxin (called verocytotoxin-producing E.coli, or VTEC) can cause severe illness. In the UK, the most common type is E.coli 0157. E.coli or Escherichia coli are bacteria that normally live in the intestines of humans and animals.Although, most strains of these bacteria are harmless, several are known to produce toxins that can cause diarrhea. One particular E.coli strain called 0157 can cause severe diarrhea and kidney damage.his is because most bacteria that cause food poisoning need time to multiply in the intestine. The length of the incubation period depends on the type of bacteria and how many are swallowed. It could be hours or days.
