Cooked ham which was supplied to independent butchers, has been linked as the source for an outbreak of salmonella in Conwy and Gwynedd.
Dr Judy Hart a consultant for Public Health Wales said: “The strain of salmonella we are investigating is very unusual so it is highly unlikely that the cases in England and Wales are coincidence. Testing has been carried out on ham supplied to a number of butchers identified as part of the investigation.”
