The algae occurs naturally, and episodes of domoic acid poisoning are not uncommon along the California coast, but the current outbreak is unusually severe.īerman Kowalewski said the dead dolphin count is “definitely the most number of animals we've seen with a domoic acid event” in her 25 years of work.īeached sea lions can appear disoriented and agitated, with symptoms such as head bobbing, foaming at the mouth, seizures and loss of motor skills. It can be fatal if consumed in high doses. The toxin enters the food chain and sickens marine mammals as they eat prey.ĭomoic acid is also a risk to people who eat crustaceans, fish and shellfish that have accumulated elevated levels, according to the California Department of Public Health. Tissue samples have been collected for tests to confirm the animals are victims of domoic acid, a neurotoxin produced by the algae Pseudo-nitzschia, according to NOAA Fisheries.
