High levels of the biotoxin which produces diarrhetic shellfish poisoning (DSP) were detected in shellfish at unsafe levels, prompting closure of recreational shellfish harvesting for all species in Henderson Inlet.
Biotoxins are produced by naturally occuring plankton which can become concentrated in shellfish. Biotoxins do not harm shellfish but can cause illness or death in humans and other mammals that eat them. Cooking does not destroy the toxin and does not make the shellfish safe to eat. Diarrhetic Shellfish Poisoning causes nausea, vomiting, abdominal pain and diarrhea. Learn more about shellfish safety at: Shellfish Protection District | Thurston County
Harvesters should always check the shellfish safety map found online or by calling 1-800-562-5632 for a recorded hotline of biotoxin closures. More information is available on the website.
