California’s commercial season for Dungeness crabs will likely be delayed, as a massive algae bloom has rendered the aquatic creatures toxic.

Dungeness crab is used in many popular dishes, particularly during the holidays.
This year some outlets for the delicacy may find their usual suppliers with little to offer, as California’s season for the crabs will likely be delayed.
The reason is that the crabs are, at this time, toxic.
A massive algae bloom has tainted the Dungeness crab population with domoic acid. 
People eating crabmeat containing the acid may experience vomiting, diarrhea, and stomach cramps.
