Washington state has banned shellfish harvesting in the waterway between Vashon and Maury island after high levels of biotoxins were discovered in the shellfish.
The Washington state Department of Health and the Public Health division of Seattle and King County posted signs at the beaches in the area warning of the fatal Paralytic Shellfish Poison (PSP) discovered in the seafood, Seattle Times reports.
PSP can be fatal if eaten and symptoms can begin immediately or within a few hours. Typically, they include tongue, lip, finger and toe tingling before potentially advancing to loss of limb control, difficulty breathing and nausea. In some instances, muscles paralysis and death can occur within 30 minutes, the Department of Health reports.
