Paralytic shellfish poison (PSP) has been detected at unsafe levels along Alki Beach south to the Pierce County line as well as on all Vashon-Maury Island beaches. As a result, the Washington State Department of Health (DOH) has closed these shores to recreational shellfish harvest.

The closure includes all species of shellfish including clams, geoduck, scallops, mussels, oysters, snails and other invertebrates; the closure does not include crab or shrimp. Crab meat is not known to contain the PSP toxin, but the guts can contain unsafe levels.

Public Health – Seattle & King County is posting advisory signs at beaches.

Harvesters are always advised to call the Biotoxin Hotline at 1-800-562-5632 or visit the Shellfish safety website before harvesting shellfish anywhere in Puget Sound.
