Mild summer weather is nice for enjoying a day at the beach. But the sunny days also create favorable conditions for poisonous bacteria that can cause illness and closures for shellfish harvesting.
Numerous beaches in the central Puget Sound area are closed to recreational shellfish harvesting. The presence of Paralytic Shellfish Poison, known as PSP, resulted in a new closure extending from Seattle’s Alki Beach south to the Pierce County line, including Vashon Island. It spread there from Kitsap County.
