The source of this outbreak has not yet been identified by the German authorities so we might see further cases in the UK in people who have recently spent time in Germany (the incubation period for this illness is 8-14 days). That is why the Health Protection Agency is advising anyone visiting Germany to avoid eating lettuce, cucumber and tomatoes, and to seek urgent medical advice if they have illness and bloody diarrhoea within two weeks of being there.

All of the cases in the UK are associated with recent travel to Germany. There have been no reports of transmission of the infection in this country and there is no evidence that any food is contaminated with this strain of E coli in the UK.

E coli bacteria usually cause diarrhoea which settles within seven days without treatment. There are many strains of the infection. Most people normally carry harmless strains of E coli in their intestine. Both the harmless strains and those that cause diarrhoea are acquired primarily through ingestion of contaminated food or water. Person-to-person and animal-to-human transmission is through the oral-faecal route
