The marine algae that produces Paralytic Shellfish Poisoning (PSP) in shellfish are declining in many areas of Jefferson County. In response to recent testing, the Washington State Department of Health (DOH) removed the biotoxin closure at certain recreational shellfish harvesting beaches in Oak Bay, Squamish Harbor, and Dabob Bay. In Quilcene Bay, harvesting butter and varnish clams is still restricted, because the PSP toxins persist in these species longer and they are unsafe to consume. Public access points are posted with warning signs and the DOH Shellfish Safety Map shows up-to-date information for recreational shellfish harvesting at www.doh.wa.gov/ShellfishSafety.htm.

Marine biotoxins are not destroyed by cooking or freezing. People can become ill from eating shellfish contaminated with the naturally occurring marine algae containing toxins harmful to humans. Symptoms of PSP can appear within minutes or hours and usually begins with tingling lips and tongue, moving to the hands and feet, followed by difficulty breathing, and potentially death. Anyone experiencing these symptoms should contact a health care provider immediately. For extreme reactions, call 911.

Recreational harvesters should also check Fish and Wildlife regulations and seasons at wdfw.wa.gov/fishing/shellfish or the Shellfish Rule Change Hotline 1-866-880-5431.
