The sand spits in Willapa Bay are referred to as the Willapa Spits and are used for commercial harvest.
Domoic acid, a naturally occurring toxin produced by certain types of algae, can be harmful or even fatal to humans if contaminated shellfish is consumed. The Washington Department of Fish and Wildlife (WDFW) routinely provides razor clams from various ocean beaches to the Washington Department of Health to test for domoic acid. State public health officials have set the unsafe level for domoic acid in razor clams at 20 parts per million and above.
See domoic acid levels at Long Beach, Twin Harbors, Copalis, Mocrocks, and Kalaloch.
