Paralytic Shellfish Poison (PSP) has been detected at unsafe levels in Quartermaster Harbor shellfish on Vashon-Maury Island. As a result, the Washington State Department of Health (DOH) has closed Quartermaster Harbor beaches 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. Crabmeat is not known to contain the PSP toxin, but the guts can contain unsafe levels. To be safe, clean crab thoroughly and discard the guts (“butter”). Working with partners, Public Health – Seattle & King County is posting advisory signs at beaches warning people to not collect shellfish.
Commercial beaches are sampled separately and commercial products should be safe to eat.
