THREE more cases of the E coli 055 strain in Dorset have been confirmed.

Lab tests today confirmed that the E coli infection and Verocytotoxin-producing Escherichia coli (VTEC) O55 has been confirmed in all three cases - seeing one of them in hospital with haemolytic uraemic syndrome.

It is the same strain found in the recently reported outbreak.

Extensive investigations are ongoing but no common source has yet to be identified.

Close family and pets of those affected are being tested.

To date there have been 30 confirmed cases of the strain since November 20, 2014.

Four were reported in May this year and there was a further case in July before the three were confirmed today.
