2022 - 2020
- September 2022: High densities of Alexandrium cells were observed by the HAB cruise in the Bering Strait region at the beginning of the month. A strong storm in Western Alaska washed up clams along the coast and harvesters are encouraged to stay alert to the signs of PSP and contact their local health care providers if they experience any of the signs after consuming shellfish.
- August 2022: Alexandrium is being observed in several regions of Alaska, including near Seward, and in the Bering Strait region where very high densities were detected by the Norseman II cruise – the nearby communities have been alerted. Toxins were elevated in shellfish in Southeast, and a possible PSP case was reported, although samples were not available to confirm.
- July 2022: Alexandrium was present in the waters of Alaska, including in the Northern Bering Sea. Shellfish testing has not been conducted extensively, but the Southeast Alaska Tribal Ocean Research network has detected high levels of PST in butter shellfish across Southeast Alaska.
- June 2022: Alexandrium is present in the waters of the Gulf of Alaska, and shellfish from Unalaska and Chignik Lagoon are testing above the regulatory limit for PST.
