Three cases of E. coli O157 have been confirmed in an outbreak at a children’s nursery on Anglesey.

Tri Ceffyl Bach Nursery in Amlwch was closed as a precaution last Thursday.

Dr Chris Whiteside, consultant in communicable disease control for Public Health Wales, said: "Given the nature of this infection it is not unusual for more cases to be identified amongst children attending the nursery. This is why the nursery was closed and the children and staff were asked to be tested.”
