“All food sample results to date have been negative for E.coli O157, but it’s important to be aware that where food has been contaminated with E.coli O157, it is not always possible to identify the bacteria on food testing.
“As an additional precautionary measure, we have advised a small number of wholesalers to cease adding some imported rocket leaves to their mixed salad products pending further investigations.”
