Public Service Announcement: South Trident Basin Alexandrium Bloom

KANA is actively observing an Alexandrium bloom at South Trident Basin, the phytoplankton responsible for paralytic shellfish poisoning!

PSP symptoms include tingling in the lips and fingertips, numbing of the arms and legs, nausea, difficulty breathing, and even death. Anyone with these symptoms should seek immediate medical care, or call 9-1-1 or their local clinic immediately.

KANA is not a regulatory agency and the consumption of wild shellfish in Alaska is considered ‘dig at your own risk’. Commercially harvested shellfish are regulated by the Department of Environmental Conservation and are considered safe for consumption.
