Alerts and Notices
Synopsis
Patients most often present in coastal locations, particularly in the Pacific Northwest and the Northeast United States. Commercially harvested shellfish is routinely tested for saxitoxin, and thus patients have typically ingested clams or mussels collected personally from local beaches.
Saxitoxin has been identified as a potential agent of bioterrorism, although it has not been used in an attack to date.
