Possible Domoic Acid​ Outbreak Sickens Sea Lions Off Malibu

MALIBU, CA — Wildlife officials believe a domoic acid outbreak has sickened California sea lions in Malibu.

The California Wildlife Center received at least 14 calls in four days for sea lions in distress.

"Though we have not confirmed the cause for these animals' illness, their signs and the recent rains make the situation highly suspicious for domoic acid toxicity," the center said Saturday on Facebook. "

Domoic acid is an algal bloom resulting from a single-celled organism called Pseudo-nitzschia. There are benign and toxic strains which animals may be exposed to through ingestion of contaminated fish.

In its toxic form, domoic acid damages the brain and heart, even in low doses, according to the California Wildlife Center. Signs in marine mammals include seizures, a craning head motion known as "stargazing," and highly lethargic or comatose states.

"These animals are suffering and confused; do not interact directly with animals such as sea lions in distress as they may lunge and bite without warning," the center advised.

Malibu residents and visitors were urged to stay away from animals on the beach and call or text the center's marine team at 310-924-7256 for assistance with animals in distress.
