Health bosses last night urged the public to remain vigilant as the number of E.coli cases linked to the Adonis Kebab House on City Road in Cardiff rose to a possible nine, with three needing hospital treatment.

Since the E.coli O157 outbreak emerged on Friday, the number of confirmed cases has risen from five to seven – with another two under investigation – but could rise further, warned Dr Gwen Lowe, consultant in communicable disease control at Public Health Wales (PHW).

Maybe health inspectors and food service operators should be vigilant before people start barfing.
