Paralytic Shellfish Poison Found In King County, Harvest Closed

SEATTLE, WA - Beaches from West Seattle to the Pierce County border are closed for shellfish harvesting due to the discovery of high levels of a nasty biotoxin. Paralytic shellfish poison can't be destroyed by cooking, and can be deadly, according to health officials.

The poison lives in meat of shellfish like clams, geoduck, and mussels. Although crabs and shrimp are not included in this harvest closure, crabs can harbor the poison in the guts - the yellow slurry found in the bottom of the carapace.

Symptoms of paralytic shellfish poisoning come on rapidly, in as little as 30 minutes. Most cases mimic food poisoning, plus tingling in the extremities and face. But the poison can cause paralysis and death.

Shellfish harvesting is generally off limits in Puget Sound from University Place north to Marysville due to pollution. You can check shellfish harvest safety via the state Department of Health.
