Sequim Bay, Discovery Bay closed to shellfish harvesting


The Clallam County Department of Health and Human Services, Environmental Health Division, announces a recreational shellfish closure in Discovery Bay due to Diarrhetic Shellfish Poisoning (DSP).

Effective immediately, the State of Washington Department of Health has initiated a closure of the following beaches for the recreational harvest of the species of shellfish listed. The downgrade was triggered after samples collected indicate DSP present in shellfish in Discovery Bay.

All species means clams (including geoduck), oysters, mussels and other invertebrates such as the moon snail. All areas are closed for the sport harvest of scallops. These closures do not apply to shrimp. 

Crabmeat is not known to contain the biotoxin, but the guts can contain unsafe levels. To be safe, clean crab thoroughly and discard the guts (butter).

It is important to know the difference between butter clams and other species of clams. Butter clams have the ability to retain toxins for a very long time — up to a year or more. Areas may be closed for the sport harvest of butter clams when all other species are safe and open. 

For more information about this closure, call the Marine Biotoxin Hotline at 800-562-5632 or visit the Department of Health’s Marine Biotoxin Website at
