FDA Expands Warning on Eating Raw Oysters from Hood Canal in Washington State

(Aug 24, 2007)--The U.S. Food and Drug Administration is warning consumers not to eat raw oysters harvested from an additional part (growing area 5) of the southern tip of Hood Canal in Washington state due to a foodborne illness outbreak caused by Vibrio parahaemolyticus bacteria. This follows an earlier outbreak and August 10 warning about oysters harvested from growing area 6 of Hood Canal.

Symptoms of the illness, vibriosis, include watery diarrhea, often with abdominal cramping, nausea, vomiting, fever, and chills. Usually these symptoms occur within 24 hours of ingestion and last no more than three days. Severe disease is rare and occurs most commonly in people with weakened immune systems. Those who believe they have experienced these symptoms after consuming raw oysters should consult their health care provider and contact their local health department.

Raw oysters harvested from growing area 5 in Hood Canal from July 31 through August 20, 2007 have caused at least six people to become ill in Washington state. To date, records indicate that raw oysters from the area were distributed to California, Colorado, Idaho, New York, Oregon, Utah, Washington state, and British Columbia (Canada).

The Washington State Department of Health has closed the growing area associated with the illness and has asked commercial oyster harvesters and dealers who obtained oysters from this area to recall them.

Consumers who have recently purchased oysters should check with the place of purchase and ask if they were harvested from the affected growing areas. The recall involves both shucked oysters and oyster in the shell (shell stock oysters).

Those with weakened immune systems, including people affected by HIV/AIDS, chronic alcohol abuse, liver, stomach, or blood disorders, cancer, diabetes, or kidney disease, should avoid eating raw oysters, regardless of where they are harvested.
