As a result, the Washington State Department of Health has closed all of Grays Harbor to recreational shellfish harvesting.
This closure impacts only the area inside Grays Harbor and does NOT affect ocean beaches.
Commercial beaches are sampled separately and commercial products should be safe to eat.
The closure includes clams, oysters, mussels, scallops and other species of mollusks. Crabs are not included in the closure.
PSP poisoning can be life-threatening and is not destroyed by cooking or freezing.
Recreational shellfish harvesters are advised to call the DOH Biotoxin Hotline at 1-800-562-5632 or access the Shellfish Safety website at http://www.doh.wa.gov/shellfishsafety.htm before harvesting shellfish anywhere in Grays Harbor.
