After making 529 people sick in a March 2009 outbreak of norovirus at his Fat Duck restaurant, Heston Blumenthal says he has stopped serving raw oysters.

At least that’s what he told the New Zealand Herald yesterday.

"I’ve not served an oyster in here, in the Crown, in the Duck or in London since that happened. I don’t know if I’ll ever change."

Today, the U.S. Food and Drug Administration advised consumers, restaurant operators, commercial shippers and processors of shellfish not to eat, serve, purchase, sell or ship oysters from Area 1642 in Apalachicola Bay, Fla. because the oysters may be contaminated with toxigenic Vibrio cholerae serogroup O75.

• Nine persons have been reported with illness. For eight, the illness was confirmed as caused by toxigenic Vibrio cholerae O75; laboratory confirmation is pending in the other person. No one was hospitalized or died.

• All ill persons reported consumption of raw or lightly steamed oysters.

• Traceback indicates that oysters harvested from Area 1642 in Apalachicola Bay, Fla., between March 21 and April 6, 2011, are associated with illness.
