Shellfish Program

Clallam County Environmental Health Services (CCEH) works to preserve and restore high quality shellfishing areas along coastal borders. Our state is the leading producer of farmed shellfish in the nation, but many beaches have been closed or ‘downgraded’ by the Washington State Department of Health due to contamination. The Environmental Health Services Shellfish Program focuses on marine biotoxin monitoring and notification along with public education.

Biotoxin Monitoring and Notification

CCEH coordinates the Olympic Baywatchers for PSP monitoring at two sites in Sequim Bay. Environmental Health Services also samples mussels at Ediz Hook biweekly to check for PSP. All of the samples collected along Clallam County beaches are sent to the Washington State Department of Health Laboratory to be tested. If a beach is closed by the State Department of Health, Clallam County notifies the public of the closure.

Volunteer Opportunities

CCEH coordinates volunteer opportunities related to Water Quality and Shellfish monitoring. The success of our shellfish restoration programs is not possible without the assistance of our volunteers. If you are interested in volunteering, please contact us at 360-417-2258.

  • Baywatchers - collect samples for Paralytic Shellfish Poisoning monitoring
  • BEACH volunteers - monitor selected saltwater swimming beaches for bacteria pollution
  • Streamkeepers - assess a variety of biological, physical, and chemical stream health indicators
  • Pollution Identification and Correction program - works to to identify, investigate, and prevent sources of pollution by coordinating certain Streamkeeper volunteer monitoring activities

Shellfish Safety

Toxic Shellfish SignThe Washington State Department of Health licenses and inspects commercial and recreational shellfish operations for safety and quality. Clallam County Health regularly sends samples to DOH labs, and utilizes health information provided by the department.

It is important to have a plan before going out to harvest shellfish. ALWAYS check for beach closures either online, calling the 24 hour Marine Biotoxin (Red Tide) hotline 1–800–562–5632, or calling the local health department. Beaches closed for recreational shellfishing will also have signs posted on site for public education of health hazards. Not all species are restricted at all times, so become familiar with different species to be able to identify species that are safe for harvest.

Molluscan shellfish are filter-feeders that ingest small particles from their surroundings, including biotoxins. Under certain circumstances, marine biotoxins ingested from eating shellfish can lead to serious health consequences. Most toxins are produced by algae and are not visibly noticeable or able to be cooked out of the shellfish, and have no antidote. Be sure to acquaint yourself with possible hazards related to shellfish consumption.

Tides are tracked for public safety and convenience.  Be sure to check for low tide before gathering shellfish, which is the best time to harvest.

Shellfish Regulations

Shellfish regulations are enforced by the Washington Department of Fish & Wildlife. Refer to their shellfish page for the most up to date information. An extensive pamphlet is available online as a free download, which contains everything you need to know before harvesting. WDFW also has an excellent Recreational Shellfish Harvest video that serves as a shellfishing 101 crash course. The video includes how to dig for and where to find various species of shellfish.Clam Plate
