The number of people infected with the E.coli infection that swept through schools and communities in south Wales rose again, this time to 156 cases.
Health officials said children there had been infected before strict hygiene controls were put in place after the first cases were reported nearly two weeks ago.
Tests to pin-point the source are continuing and health officials have yet to release any results, but investigations have centred on the John Tudor and Sons meat supply firm in Bridgend, although tests from the firm have come back negative.
