'Quite Extensive': Huge Toxic Algae Bloom Hits West Coast

An extraordinarily large mass of toxic algae off the West Coast of the United States has prompted state agencies to shut down crab and clam fisheries in at least two states, posing risks to recreational fishing and marine life.

The so-called "red tide" bloom doesn't pose a health risk to people who eat commercially caught fish, according to experts. But the Washington Department of Fish and Wildlife has shut down all crab fishing in its waters, and authorities in Oregon have closed that state's coast to digging for clams.

Such halts will likely have no significant impact on commercial fisherman, who have moved on to harvesting other species. But crabs or clams caught and eaten by recreational fishers pose a significant health risk, possibly causing seizures or even death.
