Two Pierce County beaches have been closed after unsafe levels of Paralytic Shellfish Poison were found in shellfish samples.
Shellfish harvesting is temporarily restricted at Day Island, Point Defiance, Wollochet Bay and Hale Passage, according to Tacoma-Pierce County Health Department.
A stretch of shoreline from Gig Harbor to the Kitsap County Line also remains closed.
Advisory signs will be posted at Dash Point County Park, Brown’s Point Park, Owens Beach, Point Defiance boathouse, Narrows Park, Day Island marina, Wollochet Bay boat launch and Fox Island Bridge.
The closure includes oysters, clams, mussels, scallops and other species of mollusks. Shrimp and crabs are not included.
PSP can be life-threatening. A natural marine organism produces the toxin, which is not killed by cooking or freezing.
The Health Department said more closures may be coming.
Before harvesting shellfish in Puget Sound, people are advised to call the Biotoxin Hotline at 800-562-5632 or www.doh.wa.gov.ehp/sf/biotoxin.htm.
