CLAMMING NEWS RELEASE UPDATE

RECREATIONAL RAZOR CLAM UPDATE: No future razor clam dates will be announced until domoic acid levels in razor clams drop below the action level. We will continue to test every two weeks. To see previous results see the web link below.

MARINE TOXIN UPDATE:

Recall, before a beach can be opened for the harvest of razor clams, WDOH protocol requires that all razor clam samples collected from that beach must test under the action level (20 ppm for domoic acid; 80 µg/100g for PSP; and 16 µg/100g for DSP) on both of two required sample collections, that must be spaced 7 to 10 days apart.

As we reported in December, razor clams are following the historical pattern of slowly depurating (losing) domoic acid. We also are observing the levels “bounce around” some, as they have in past events. This is a result the individual 12 clams we harvest when we are collecting samples. The toxin “load” can vary greatly between individual clams. The laboratory protocol requires the clams to be cleaned and then the meat from all 12 (per area) are blended together. Then a sample of that mixture is analyzed and one result is reported for that area.  If you are interested, you can check out the historical domoic acid data at the link below.

These results and the historical record of domoic acid events can be found at: https://wdfw.wa.gov/fishing/basics/domoic-acid/levels  (click on “show historical data”) and then hover your curser over the data points for more detail).

Along with sampling collecting razor clam every two week, WDFW together with our colleagues in the ORHAB (Olympic Region Harmful Algal Bloom) partnership continue on-going observations of the surf zone phytoplankton assemblages.
