Last July, researchers detected high concentrations of a toxin-producing algae offshore in the Bering Strait region.

Storms can bring a bounty to the beach - driftwood sometimes or in this case, clams! But be careful out there. There are new concerns about emerging levels of harmful algae in Western Alaska waters, which could impact shellfish and human health.

After alerting the region to very high levels of harmful algal blooms west of Kotzebue and Gambell two weeks ago, scientist onboard the research vessel Norseman II have found even higher numbers of Alexandrium catenella algae cells near Wales, Diomede and Shishmaref.

A six-inch butter clam harvested on August 28 three miles north of Savoonga tested positive for saxitoxins, or paralytic shellfish poison, Norton Sound Health Corporation Environmental Coordinator Emma Pate said.The clam itself showed high levels of saxitoxin present: it had 450 micrograms of toxin per 100 gram of body tissue. The Food and Drug Administration’s safety limit is at 80 micrograms/100 g. Pate, via the SEATOR lab, on Sept. 23 issued a paralytic shellfish toxin advisory to Savoonga and Gambell.

Researchers stepping off the research vessel Norseman II in Nome last weekend, brought significant news of having found very high concentrations of a phytoplankton called Alexandrium catenella in regional waters. Alexandrium is an algae that can produce saxitoxins, which can cause dangerous paralytic shellfish poisoning in people. The scientists issued an advisory, notifying Norton Sound Health Corporation, UAF Sea Grant and the Alaska Division of Public Health.

Scientists have detected toxic algae in clams from the Bering Strait and Chukchi Sea regions of northern and western Alaska, according to a new bulletin. This set of clams was taken on August 22, 2019 about 50 miles north of Cape Lisburne.
