Doctor's Note

This video is about natural toxins that bioaccumulate up the food chain, but the same happens with industrial pollutants. See, for example, Xenoestrogens & Sperm Counts and Fish Intake Biomarker. Some of the other unusual conditions to strike fish consumers are profiled in Sexually Transmitted Fish Toxin, New Corpse Smell, Allergenic Fish Worms, Fish Fog and Greasy Orange Rectal Leakage. There are about 50 videos on fish and hundreds more on more than a thousand other topics.

For more context, check out my associated blog post, Mercury Testing Recommended Before Pregnancy.

      All smells a bit fishy to me.  Let’s ask the keeper of Domoic Acid, Mr. Domo himself:  http://www.DomoNation.com. Was it his love for Brain Freeze that he ate the Slurpee again or the Amnestic disorder from being king of Domoic acid.  I don’t think there is Domoic Acid in Slurpee’s is there.

    However, domoic acid only concentrates in the guts of fish and shellfish, so the muscle tissues of predator fish like tuna should be relatively (and I’ll only say relatively) safe.  We don’t know a lot about the effects of low exposures of domoic acid, only acute exposure.  

    Diagnosed acute exposures only come from blooms, like that in the 80s in maritime Canada, where the case you highlighted occured and over a hundred people were hit from eating contaminated mussels — which are consumed with the guts and all.

    It’s likely because most clinicians don’t know enough about ASP to recognize it, that many cases go undiagnosed every year.  I’m speaking, not as a clinician, but as a person who probably got ASP from eating mussels in 2007, and now live with memory issues (not as bad as you describe, thank God) and epilepsy, but my intellect intact.  

    Another point of interest — it was a bloom resulting in gulls being stricken with domoic acid poisoning when Alfred Hitchcock was a child — disoriented and sick, they fell to the ground and attacked any human that came near — that inspired the movie “The Birds.”  Just last year, a researcher went into tissue archives, and proved that samples taken from the birds sickened in that bloom were suffering from domoic acid poisoning!
