The Current Crab Biotoxin Lab Results provide essential information about recent crab biotoxin data, helping ensure safe recreational and commercial harvesting. Domoic Acid (DA), measured in parts per million (ppm), is the primary concern due to its potential risks. Zones exceeding the DA closure limits—30 ppm for crab viscera and 20 ppm for crab meat—will be marked in red, indicating closures. Adjacent zones may also be affected due to the mobility of crab populations.
Refer to the detailed results and zone-specific closures in the document below. For more information, check out the Biotoxin Map on our website, highlighting recreational shellfish closure areas.
