Here are the most recent marine toxin levels, as announced by the Washington Department of Health on Wednesday, March 20. This is the final round of razor clam samples required by WDOH before any recreational razor clam opener.

Next digs are Thursday, March 28 at Twin Harbors, minus-0.3 feet at 7:57 a.m.; Friday, March 29 at Twin Harbors, Long Beach, Copalis, Mocrocks, -0.6 at 8:40 a.m.; Saturday, March 30 at Twin Harbors, Long Beach, Copalis, Mocrocks, -0.7 at 9:26 a.m.; and Sunday, March 31 at Twin Harbors, -0.6 at 10:16 a.m.

 

Before a beach can be open 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 all required sample collections.

Note that in all of these samples; only razor clam meat tissue is tested.

These samples were all collected on Sunday, March 17.

Long Beach Reserve: Domoic acid =  1 parts per million; PSP no detection; and DSP no detection.

Twin Harbors Area CL (middle): Domoic acid =  1 parts per million; PSP no detection; and DSP no detection.

Copalis Area XL (middle): Domoic acid =  less than 1 parts per million; PSP no detection; and DSP no detection.

Mocrocks Area CP (south): Domoic acid =  less than 1 parts per million; PSP no detection; and DSP no detection.
