Domoic acid

Domoic acid is a natural toxin produced by certain types of algae, especially during harmful algal blooms. Marine animals like shellfish, such as mussels and scallops, can accumulate the toxin from the water. When humans consume contaminated seafood, they may experience poisoning called amnesic shellfish poisoning, which can cause symptoms like nausea, vomiting, abdominal cramps, and memory loss. Domoic acid is a concern for public health and marine ecosystems, prompting monitoring and seafood safety regulations to prevent illness.
