Tests show high levels of marine biotoxin paralytic shellfish poison (PSP) 

CLOSURE AREA: Port Madison, Miller Bay, and Port Orchard Passage from the Agate Pass Bridge to Illahee State Park, including all bays and inlets. Check the state shellfish safety map to view specific locations.

All existing shellfish closures remain in effect.  

SPECIES AFFECTED: All recreational shellfish harvesting for all species of clams, oysters, and mussels.

Shrimp and crab are not included in this closure, but crabs should be cleaned prior to cooking, and the “crab butter” should be discarded. 

Anyone planning to harvest or consume local, recreationally-harvested shellfish must first:

SYMPTOMS OF PSP:  Early symptoms of PSP include tingling of the lips and tongue, which may begin within minutes of eating toxic shellfish or may take an hour or two to develop. Symptoms may progress to tingling of fingers and toes and then loss of control of arms and legs, followed by difficulty in breathing. Some people feel nauseous or experience a sense of floating. If a person consumes enough toxin, muscles of the chest and abdomen become paralyzed, including muscles used for breathing, and the victim can suffocate. Death from PSP has occurred in less than 30 minutes.
