PORT TOWNSEND — Public health officials in Jefferson County have announced closures of multiple beaches for recreational shellfish harvesting due to high paralytic shellfish poison levels in shellfish samples sent to the state Department of Health.
Closures are now in effect for:
• Discovery Bay, including the northern Quimper Peninsula around to Point Hudson.
• Admiralty Inlet and East Marrowstone Island.
• Kilisut Harbor, including Mystery Bay and Fort Flagler State Park.
• Oak Bay, Mats Mats Bay and Port Ludlow.
Paralytic shellfish poison is a biotoxin released by the marine plankton Alexandrium. Shellfish eat this plankton and the biotoxin can accumulate in their meat.
Symptoms of paralytic shellfish poisoning, which can appear within minutes or hours, include tingling of the lips, tongue, hands and feet, followed by difficulty breathing and paralysis.
Paralytic shellfish poisoning can be fatal. People experiencing these symptoms after consuming shellfish should call 911. The heat-stable toxin is not destroyed by cooking or freezing.
Butter and varnish clams retain the toxin longer than other species, which is why they often remain closed longer than other species.
Crabmeat does not retain the biotoxin, but it can be present in crab guts and butter, the white-yellow fat inside the back of the shell, so they should be thoroughly cleaned and the crab butter and guts should be discarded.
