County issues total shellfish ban
Tuesday, August 22, 2006
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. Fin fish found in these waters do not accumulate the toxins in their flesh.
Marine biotoxins are not destroyed by cooking or freezing and can be life-threatening. Symptoms of paralytic shellfish poisoning may appear within minutes or hours and usually begins with tingling lips, tongue, hands and feet followed by difficulty breathing, and potentially death. Any one experiencing these symptoms should contact a health care provider. For extreme reactions call 911.
The toxin is produced by naturally occurring "blooms" of microscopic plankton that tend to be more common during the warmer months of the year. The color of the water does not change and the plankton are invisible.
