Shellfish Safety Information

Fishing Regulations Icon Washington Fishing

Eating contaminated shellfish or seaweed can cause serious illness or death. The only way to be safe is to “Know Before You Dig”. Always check for current beach closures and advisories related to biotoxins, pollution, or other human health concerns the same day you plan to harvest: www.doh.wa.gov/shellfishsafety (clickable map), or call the Department of Health at (360) 236-3330 or the local county health department. For biotoxin information only, call the toll-free Biotoxin Hotline at 1-800-562-5632. In addition, some beaches may be posted with warning signs — look for signs as you access the beach.

Always check both the current wdfw season and the doh health closure status before harvesting any public beach.

Biotoxin Closures

Don’t harvest in areas with marine biotoxins, also known as “Red Tide”. You could get sick or die.

Paralytic Shellfish Poisoning (PSP) & Amnesic Shellfish Poisoning (ASP) & Diarrhetic Shellfish Poisoning (DSP):

  • Can make you sick or cause death
  • Can’t be destroyed by cooking or freezing
  • Are produced by algae and do not always turn the water red
  • Can remain in butter and varnish clams longer than in other shellfish species

Pollution Closures

Don’t harvest in areas that are polluted. You could get sick.

Pollution can come from many sources like sewage drain pipes, failing septic systems, farm practices, boats, and pet waste. Some closures and advisories are listed on page 131. Visit www.doh.wa.gov/shellfishsafety for the current beach status.

Vibrio Warnings

Be aware of Vibrio Warnings. You could get sick.

Vibrio Bacteria:

  • Cook all shellfish thoroughly to kill the bacteria and to avoid getting sick
  • Highest risk from May-September, especially in Puget Sound and Hood Canal
  • Are naturally occurring bacteria that can multiply rapidly in warm conditions

Help Keep Our Waters Safe and Clean

Human and pet waste can make people sick and cause harvest closures. Please do your part to protect our waterways and shellfish beaches:

  • Use public toilets. Scoop, bag and trash human waste if no facilities are available.
  • Scoop, bag, and trash your pet’s waste.
  • Pump, don’t dump! Use pumpout stations to dispose of boat sewage. Visit https://pumpoutwashington.org.


Don’t Relocate Shells or Shellfish!

Like humans and other animals, shellfish can get sick. It is illegal to move shells and shellfish from beach to beach or between state waters without a transfer permit. When you move animals and shells from one area to another, you can accidentally introduce or spread harmful pests and diseases. These movements include activities like:

  • Transferring shellfish to seed your beach
  • Putting used oyster shells on beaches
  • Storing shellfish harvested from other areas or bought from the store on a beach or off a dock
  • Releasing any aquatic animals into state waters for any reason.

Help safeguard Washington shellfish. For more information, visit https://invasivespecies.wa.gov/priorityspecies/infectious-shellfish-diseases/. To apply for a transfer permit visit https://wdfw.wa.gov/licenses/fishing/shellfish-import-transfer.
