Strains of E. coli can cause severe stomach cramps, bloody diarrhoea and vomiting.

Now, Dr Richard Othieno, consultant in public health medicine, NHS Lothian, has confirmed they are aware of “a small number” of confirmed cases of E. coli O157 in children in the county.

He said: “We’re aware of a small number of confirmed cases of E. coli O157 in children from East Lothian.

"E. coli O157 is a bacterial infection that can cause diarrhoea, bloody diarrhoea, tummy cramps and occasionally fever.

"NHS Lothian, along with partner agencies, is investigating the source and has put in place control measures.

"There is no specific treatment for E. coli O157 infection and most people who are infected will get better without medical treatment.

"However, those who have symptoms, or are concerned, are advised to contact their GP or NHS 24 on telephone number 111.”
