OLYMPIA - State health officials warn that a type of biotoxin never before found in Washington shellfish has been detected in shellfish from the Sequim Bay area. The discovery led to a commercial and recreational harvest closure in Sequim Bay, and people are urged not to eat shellfish from that area until further notice due to the risk of Diarrhetic Shellfish Poisoning (DSP). A recall was conducted for commercially sold products from the area dating back to August 1; all recalled product has been accounted for and is not currently on the market.
This is the first time in Washington or the United States that DSP toxin has been found above acceptable food safety limits. Since this is new to the state, the Department of Health is sampling and testing shellfish areas throughout the state to learn more about it. New information will be shared as it is received.
