Over a dozen sea lions sickened by toxic algae in Malibu
- At least 14 sea lions have been reported sick in Malibu, possibly due to exposure to domoic acid toxicity.
- Recent rains may have contributed to the algal bloom suspected in these cases.
- Wildlife officials are advising the public to avoid direct contact with sick sea lions and report sightings to the authorities.
In Malibu, California, wildlife officials have reported that at least 14 sea lions have been found sick over the past few days, raising alarm over potential domoic acid toxicity. This occurs due to exposure to harmful algal blooms, particularly from the single-celled organism Pseudo-nitzschia, which can contaminate marine life and pose health risks to both animals and humans. The California Wildlife Center stated that they have received multiple calls regarding distressed sea lions, with symptoms observed including seizures, lethargy, and unusual craning head motions known as 'stargazing.' Disturbed beachgoers are cautioned against approaching these animals, as they can respond aggressively when in distress. Current conditions, including the recent rains, have heightened suspicion regarding this algal bloom and its effects. Domoic acid toxicity is not new to the region; it has previously affected numerous marine animals along California’s coast. Wildlife officials noted that back in August, around 90 sea lions and various other marine species exhibited similar symptoms of poisoning. The health implications extend beyond marine animals; humans who consume contaminated seafood may also suffer serious health issues, known as amnesiac shellfish poisoning. Early symptoms in humans can include gastrointestinal disturbances, which escalate into neurological symptoms as the condition worsens. Both animals and humans alike can be affected by either benign or toxic strains of domoic acid, emphasizing the cross-species risks stemming from marine environmental health concerns. The California Wildlife Center is actively monitoring the situation and is urging beachgoers to report any encounters with distressed sealife, as immediate intervention is crucial for recovery. In conclusion, the recent outbreak highlights the persistent threat posed by toxic algal blooms in coastal areas and necessitates ongoing awareness and investigation. It serves as a reminder of the interconnectivity within marine ecosystems, emphasizing the need for preventive measures and public education to mitigate risks associated with contaminated fish and shellfish consumption.
