County issues total shellfish ban
High levels of marine biotoxins that cause paralytic shellfish poisoning have been detected at concentrations above the safe level in shellfish samples throughout King County.
As a result, the Washington State Department of Health has closed all beaches to the harvest of all species of shellfish in King County, including Vashon Island.
The closure includes clams, oysters, mussels, scallops and other species of shellfish. Crab is not included in the closure, but the "crab butter" should be discarded, and only the meat should be eaten.
