Ingesting the neurotoxin can make people extremely sick, and cause death in the worst cases. Symptoms of domoic acid poisoning may include vomiting, diarrhea, abdominal cramps, headache and dizziness and can occur within 30 minutes to 24 hours after eating the toxic seafood.

The warning will likely lead to a delay in the start of the crab season, which was scheduled for November 15.
