The California Department of Public Health (CDPH) is warning consumers not to eat recreationally harvested bivalve shellfish (such as mussels, clams or whole scallops) from Monterey or Santa Cruz counties due to dangerous levels of a naturally occurring toxin that can cause illness or death.
Dangerous levels of domoic acid have been detected in mussels from this region. This toxin, also known as Amnesic Shellfish Poisoning (ASP), can cause illness or death in humans. No cases of human poisoning from domoic acid are known to have occurred in California.
