State and county public health officials announced the closure of Port Townsend Bay to shellfish harvesting on Aug. 30, after testing indicated high levels of the biotoxin that causes Paralytic Shellfish Poisoning (PSP). 

With the closure, the recreational harvest of all species of molluscan shellfish including clams, oysters, mussels, and scallops is prohibited. Staff with the Jefferson County Public Health Department posted danger signs at public access points in the area. 

While crab and shrimp are not included in the closure, toxins can accumulate in crab gut and butter (the white-yellow fat inside the back of the shell). Health officials recommend cleaning crab thoroughly and avoid eating the crab butter and guts. 

In addition, and after a recent shellfish closure on August 14, 2024, department of health officials reopened Quilcene and Dabob Bay for recreational shellfish harvesting on August 29.

Paralytic Shellfish Poisoning (PSP) can be fatal. The illness is caused by eating shellfish contaminated with toxins from the naturally occurring marine plankton Alexandrium. 

The biotoxin is not destroyed by cooking or freezing. Symptoms of PSP can appear within minutes or hours, and usually begin with tingling lips and tongue, moving to the hands and feet, followed by difficulty breathing and paralysis. Anyone experiencing any of these symptoms after consuming shellfish should contact a health care provider immediately. For extreme reactions, call 911.
