Washington, Pierce Counties Close Beaches for Paralytic Shellfish Poison

Washington State has closed multiple beaches to recreational shellfish harvesting due to high levels of paralytic shellfish poison (PSP), a dangerous biotoxin produced by microscopic algae. Closures affect areas including Vashon Island and Pierce County shorelines from Days Island to Point Fosdick, extending north to King and Kitsap County lines. PSP can cause severe illness and death rapidly by paralyzing muscles, including those required for breathing, with symptoms beginning as tingling in the lips and tongue. Authorities advise the public to avoid harvesting shellfish in affected areas and to seek immediate medical help if symptoms occur. Commercial shellfish harvesting sites are being monitored and regulated, and shellfish sold in stores and restaurants remain safe to eat. Meanwhile, in Malaysia, the Negeri Sembilan Fisheries Department has urged fishers to halt shellfish harvesting in Port Dickson due to elevated biotoxin levels linked to harmful algal blooms, with further testing and potential bans underway.
