San Diego health officials have traced an outbreak of Vibrio parahaemolyticus to oysters from Washington State.  A consumer warning was posted on 10News.com today:

The County of San Diego Department of Environmental Health is alerting consumers about oysters from the southern part of Hood Canal in Washington State that may be linked to several cases of an intestinal disease in California and San Diego County.

County health officials were notified that some oyster-growing areas in Hood Canal have been closed due to concerns over Vibrio parahaemolyticus, a foodborne illness which can be caused by eating raw or undercooked shellfish.

Three cases in the San Diego area are currently under investigation. Environmental Health staff is checking local food facilities for the product.

Tip:  Don’t eat oysters in months without an "r":  May, June, July, August.
