E.coli is a bacterial infection that can cause severe stomach pain, bloody diarrhoea and sickness. In severe cases it can cause kidney failure, according to Public Health Wales
The most common type of bacteria that causes illness is E.coli 0157. It is very infectious and people can become infected from eating contaminated foods, particularly inadequately cooked minced beef and milk. However, some outbreaks have been associated with yoghurt, cooked meats, meat pies, cheese, dry cured salami, raw vegetables, salad vegetables, unpasteurised apple juice and water.
People can also become infected with E.coli from direct contact with animals or contaminated environments. The illness can range from mild diarrhoea to bloody diarrhoea. A severe complication of the condition occurs in up to 10% of patients, called haemolytic-uraemic syndrome. It can be fatal.
An outbreak of E. coli O157 occurred in September/October 2005 with cases recorded in 44 different schools in the south Wales valleys. In total 157 people, mainly children, fell ill and a five-year old child died.
What are the symptoms of E.coli?
- diarrhoea
- stomach cramps

When to see a doctor
According to the NHS, there is no specific treatment for E.coli 0157 infection. People who are infected can usually be cared for at home and most will get better without treatment. It is important to drink plenty of fluids as diarrhoea can lead to dehydration.
However it is important to go to your GP if you or your child has bloody diarrhoea.
Anyone who has had an E.coli infection should stay away from work or school until they have been free of symptoms for 48 hours.
Anyone who is suffering with diarrhoea or vomiting is advised to take some simple hygiene precautions to reduce the risk of passing the illness onto others:
- Wash hands thoroughly before eating, preparing food and after going to the toilet. It is preferable to use liquid soap.
- Where possible, don’t prepare food for others.
- Wash any soiled bedding or clothing on as high a temperature as possible.
- Provide separate towels for anyone who is ill.
- Clean all surfaces, including food preparation surfaces and door handles on a regular (at least daily) basis with usual cleaning materials.
