SFist alerts you to the risk of “sport-caught shellfish” from Santa Cruz county carrying a neurotoxin called domoic acid, which causes amnesic shellfish poisoning (ASP). Of course, the key is that most shellfish people buy in stores or eat in restaurant is commercially caught, and thus “subject to frequent and mandatory testing.”
Domoic acid buildup in shellfish is caused by certain algal blooms. ASP can cause brain damage in humans, and seizures in marine mammals. Sounds awesome.
