Toxins in Maine shellfish prompt recall and ban on harvests

The ban, which remains in effect until further notice includes areas east of a line drawn south from Point of Maine (Machiasport) to the limit of U.S. jurisdiction; AND west of the U.S./Canadian border.

The notice by the two agencies ban the harvest of clams, mussels, European oysters, surf/hen clams, or carnivorous snails from the shores, flats, and waters of the aforementioned coastal areas because tests have shown high levels of domoic acid, a naturally occurring marine neurotoxin produced by certain types of algae.

While there have been no reports of illness, Food Safety News reports that excessively high levels of domoic acid can cause serious health problems, including amnesic shellfish poisoning (ASP), and even death. Keep in mind, too, that freezing or cooking of the shellfish will not remove the deadly neurotoxin.

In August, Digital Journal reported on the decline of an iconic “foundation species, the blue mussel, because of warming ocean waters along the northeastern coast of the United States.

And one of the sad consequences of warming waters is the increasing chances of algae formation or algae blooms. People on the west coast of the U.S. and on up into Canada have become very familiar with harvest bans because of the presence of domoic acid in shellfish.

We are deeply saddened to announce the passing of our dear friend Karen Graham, who served as Editor-at-Large at Digital Journal. She was 78 years old. Karen's view of what is happening in our world was colored by her love of history and how the past influences events taking place today. Her belief in humankind's part in the care of the planet and our environment has led her to focus on the need for action in dealing with climate change. It was said by Geoffrey C. Ward, "Journalism is merely history's first draft." Everyone who writes about what is happening today is indeed, writing a small part of our history.
