The Washington Department of Health (WDOH) has closed all recreational shellfish harvesting in Willapa Bay due to increasing levels of the marine toxin domoic acid.
Biotoxins are marine toxins that can concentrate in shellfish to dangerous levels, making the shellfish unsafe to eat. Paralytic Shellfish Poisoning (PSP or "red tide"), Amnesic Shellfish Poisoning (ASP or "domoic acid"), and Diarrhetic Shellfish Poisoning (DSP or "okadaic acid") are the biotoxins commonly found in Washington's marine waters.
At this time there is no commercial closure. Although commercial harvesters have been contacted directly by WDOH with additional instructions.
All questions should be referred to the Washington Department of Health.
