The Closure Includes Several Species of Shellfish

• Clams
• Geoduck

What Are the Symptoms of Paralytic Shellfish Poisoning?

Early symptoms 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 symptoms are severe, call 911 or have someone take you to the emergency room.

If symptoms are mild, call your healthcare provider or the Washington Poison Center at 800-222-1222.
