A full day's production of cheese may have to be destroyed after the Duke of Edinburgh failed to wear hygiene gear during his visit to an Australian cheese factory on Tuesday.
Prince Philip visited the factory in Wagga Wagga, southwest of Sydney, as part of a Royal tour with Queen Elizabeth the Second, but he declined to don a sterile coat and cap.
Now the batch under production probably won't be offered for sale.
Even wet weather couldn't deter royalists who lined the entrance to Sydney's Children's hospital for a glimpse of their Queen.
And they were not to be disappointed.
Small crowds meant there was plenty of room to view the Queen, wearing a red and white patterned dress and jacket with a white hat and bag.
This is Queen Elizabeth's first visit to Australia since voters decided in a referendum to retain her as their head of state.
She began the fourth day of her 16-day tour mingling with hospital staff and patients at Sydney's Children's Hospital, and unveiling a plaque to commemorate her visit there.
Security was beefed-up for the visit following a scare on Monday when a man was found to have a knife strapped to his leg outside the Queen's scheduled lunch venue.
But the Queen's visits were relatively low-key affairs. On Tuesday, it was her husband Prince Philip, Duke of Edinburgh who was grabbing the headlines.
His trip to a cheese factory may result in a full day's cheese production being destroyed.
The problem? The Duke of Edinburgh failed to wear a hygiene cap and gown.
Prince Philip visited the a cheese making facility on the campus of Charles Sturt University in Wagga Wagga, 400 kilometres (250 miles) southwest of Sydney.
But he declined to don a sterile white laboratory coat and soft cloth cap over his navy blue suit.
Cheese maker Barry Lillywhite said the batch under production at the time would be tested for contamination, but would probably not be offered for sale.
Later on Tuesday, Prince Philip enjoyed trying to impress crowds with his ceremonial skills.
"You are going to watch the world's leading plaque unveiler at work"
SUPER CAPTION: Prince Philip, Duke of Edinburgh
And Queen Elizabeth visited the site of Sydney's 2000 Olympics, opening on September 15.
The Queen has not been invited to attend the opening ceremony.
In a break with tradition, Australia bypassed its head of state as the dignitary who will declare the Games open.
The country's highest government official, Prime Minister John Howard, will not perform the function either. He withdrew from the role after being accused of hypocrisy because he is a monarchist.
In the end, the role was handed to the queen's representative in Australia, Governor-General Sir William Deane - an official almost unknown outside Australia.
During her visit, the Queen was shown through the Games' basketball and swimming venues, the athletes' village and Stadium Australia, where a capacity crowd of 110-thousand people is expected to watch the opening and closing ceremonies.
