More hospitalised in Qld with salmonella

Twenty-five people have now tested positive for salmonella linked to contaminated mayonnaise served at 40 Melbourne Cup functions, including the 11 who needed hospital care.

Three people are still in hospital.

The contamination, revealed on Thursday, contributed to the death of a 77-year-old woman.

A further 165 people are suspected of having been poisoned after reporting symptoms, according to Metro North public health unit director Dr Susan Vlack.

Health officials say up to 700 people could have been exposed to the bacteria.

Piccalilli Catering said on Thursday it was the company at the centre of the scare, blaming eggs from a wholesaler it has since dumped.
