State agriculture officials in Oregon have shut down commercial and recreational crabbing along the entire coast because of high levels of domoic acid found in the crabs' flesh.
The Oregon Department of Agrilculture says the ban includes the harvest of Dungeness and red rock crab in bays and estuaries, off docks, piers, jetties and in the ocean.
Consumption of domoic acid can result in dizziness, headaches, vomiting and diarrhea. More severe cases can result in memory loss and death.
