Domoic acid (DA) is a neurotoxin known to cause Amnesic Shellfish Poisoning (ASP) in humans and other predators that consume contaminated aquatic organisms that have consumed P. australius. [16] DA has been isolated in several species of red algae, but is produced mostly by members of the Pseudo-nitzschia genus. Chemical structure of domoic acid
