What is the problem?
Raw oysters harvested and shipped from Hood Canal Area 4 in Washington State between August 30 and September 19 have been linked to illnesses caused by Vibrio parahaemolyticus bacteria.

What are the symptoms of Vibrio illness?
Illness is typically characterized by nausea, vomiting, and diarrhea. The symptoms begin from a few hours up to five days after consumption of raw or undercooked seafood, particularly shellfish, or after ingestion of surface waters.

Who is at risk?
Persons at risk are those who traveled to Washington State and consumed oysters that were harvested from Hood Canal Area 4 or who purchased oysters in a state to which these oysters were distributed and ate them.  Individuals with weakened immune systems, including people affected by AIDS, chronic alcohol abuse, liver, stomach, or blood disorders, cancer, diabetes, or kidney disease can be more susceptible to vibrio illness and should avoid eating raw oysters, regardless of where they are harvested.

What Do Consumers Need To Do? 
Consumers in the affected states should inquire of the retailer, restaurant, or other facility about the source of the oysters offered for purchase. If the oysters were definitely or possibly harvested from Hood Canal Area 4 in Washington State, and have not yet been consumed, they should not be eaten. If the oysters were already consumed and no one became ill, no action is needed. If you develop a diarrheal illness within a week after consuming raw or undercooked shellfish, see your healthcare provider and inform the provider about this exposure.

Where Were the Oysters Distributed?
Records obtained by Washington State health officials indicate that raw oysters from this area of the Hood Canal in Washington State were distributed to 23 states: Alaska, Arizona, California, Colorado, Connecticut, Florida, Hawaii, Illinois, Indiana, Maryland, Minnesota, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Virginia, Utah, and Washington, and to the countries of China, Indonesia, Taiwan, and Thailand.

What is Being Done about the Problem?
The Washington State Department of Health has closed Area 4 of Hood Canal to shellfish harvesting. All product harvested and shipped between August 30 and September 19 has been recalled. Washington State has notified all other states where product was shipped that they should hold and destroy product.
