KOMO News has an article - Shellfish contaminated by toxic algae may cause paralysis - about an algae bloom. Due to the holiday weekend, we haven't received any news release from San Juan County. The Washington Dept of Health has a safety map, Recreational Shellfish beach closures listed by county, a fact sheet on vibriosis and much more information on its website.
Commercial operations are separate from the recreational information. The commercial closure information is posted here.
