“The wedding went really well . . . but the aftermath was terrible.”

That’s what one guest at a wedding reception told The West after a bride and seven wedding guests – including the wife of the State’s top health adviser – became ill after a wedding reception at one of Perth’s most exclusive restaurants.

Former Princess Margaret Hospital director of emergency Gary Geelhoed, who took over as WA’s chief medical officer this month, told The West Australian several people became ill after the wedding at Fraser’s restaurant in Kings Park on Saturday.

Dr Geelhoed said the Health Department was investigating.

“I’m not sure what happened – certainly people got sick, but whether it’s related (to the food) or not, I’m not sure,” he said.

Fraser’s chef and co-owner Chris Taylor said the restaurant was co-operating with the Health Department’s investigation and was aware of the claims of food poisoning.

It is understood more than 100 people were at the event.

Fraser’s spokeswoman Samantha White said the restaurant had been contacted by the wedding party and had “gone through a number of processes” after the allegations were raised.
