Comment Re:Possibly a marine toxin (Score 1) 102
Cyanobacteria growing on invasive water-thyme(Hydrilla verticillat that super-accumulates bromine) create neurotoxins with that element (comes from some weed killers, misc. anthropogenic, and natural sources.) They're toxic to all sorts of aquatic organisms and raptors that prey on them as well. Investigation on toxicity to mammals is planned. (URL: https://www.newscientist.com/a...).
I remember reading the BMAA related articles a whiles back, (URL: https://academic.oup.com/toxsc...)
It's a confounded problem. For instance, IIRC, throughout the year depending on local climate there are algae blooms at some body of water or other, but not necessarily any formalized fine grain testing + warning/notification system in place for the consumer fisher/hunter/gatherer (other than avoid fishing in bloom and avoid fish/crustaceans near a bloom.) BMAA or other multitude of toxin testing is likely impractical for the consumer as well. What is the prudent path to allow recreational water use/foraging while not being paralyzed by insidious risks.(see related: https://www.theguardian.com/en... and https://www.cdc.gov/habs/gener...)
