Elevated biotoxins close recreational shellfish harvest in Birch Bay

Shellfish harvesting in northern Whatcom County has been suspended due to unsafe levels of paralytic shellfish poisoning found in Birch Bay. The Washington State Department of Health has closed recreational harvesting from Sandy Point to the Canadian border, affecting areas like Drayton Harbor and Point Roberts. This is the second closure this summer, following a previous ban that lasted from July 16 to August 1. Molluscan shellfish, which include clams, mussels, oysters, and scallops, are particularly at risk, with mussels showing the highest toxin concentrations. While locally harvested crab meat remains unaffected, crab butter and entrails could contain harmful biotoxins and should be discarded.

Symptoms of PSP, which can manifest within minutes, include numbness and tingling in the lips and tongue. The toxin cannot be eliminated by cooking or freezing. Residents are encouraged to check the Washington Shellfish Closure map or call the Department of Health Biotoxin Hotline to ensure safety before harvesting shellfish.
