E.coli O157

VTEC areecoli a group of bacteria which cause illness in humans. The most important VTEC strain to cause illness in the UK is E. coli O157. Symptoms can range from mild gastroenteritis to severe bloody diarrhoea, mostly without fever, through to two serious conditions known as haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopaenic purpura (TTP) that affect the blood, kidneys and in severe cases the central nervous system.

 People can become infected by:

  • Eating contaminated food
  • Contact with infected animals either directly or through inadvertent contact with animal faeces (e.g. at farms, petting farms and campsites); 
  • Contact with other people who have the illness (i.e. through inadequate hand hygiene after using the toilet and/or before food handling); 
  • Drinking water from inadequately treated water supplies; 
  • Swimming or playing in contaminated water such as ponds or streams.

The PHA advises that everyone follows some simple rules to prevent the spread of E coli - not just those with symptoms, but everyone should wash their hands after using the toilet and before eating or preparing food. Raw and cooked food should be kept completely separate, raw meat should be cooked through and vegetables and fruit should be washed thoroughly before eating.
