ecoli 0157 is a very harmful strain of ecoli that can cause fatal kidney failure. It is also known as VTEC (verocytotoxin producing e coli). The organism infects by adhering to and colonizing the intestinal tract and releasing the toxin. symptoms are kidney failure which can be fatal (haemolytic uraemic syndrome), and bloody diarrhoea. The main source of infection is cattle; faeces is transferred to the carcas during slaughter or milking. Therefore infection can be prevented by adequate cooking and pasteurization of milk.
