Vashon’s Quartermaster Harbor closed to recreational shellfish harvesting

Vashon-Maury Island’s Quartermaster Harbor has been closed to recreational shellfish harvesting because of unsafe levels of paralytic shellfish poison (PSP).

King County and state health officials Thursday issued this alert:

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.
