A few weeks ago, we reported on the recent toxic algae bloom (also known as red tide) that was affecting both marine and land animals that depend on the ocean and nearby ecosystems. Some of the consequences of this outbreak included the appearance of hundreds of infected sea lions, along with several dead animals such as pelicans, dolphins, and even whales washing up on local shores.
Now, state health officials are warning about a new danger—this time to humans. The California Department of Public Health (CDPH) has announced a quarantine on all recreationally harvested mussels along the entire coastline, effective from May 1 through October 31. However, it’s important to note that this advisory does not apply to commercially sold shellfish from certified sources.
The quarantine aims to protect the public from shellfish poisoning due to the presence of domoic acid, which can cause severe illness, including coma and even death. This mussel quarantine is in addition to existing shellfish safety advisories against consuming sport-harvested bivalve shellfish, including mussels, clams, scallops, and oysters. The main counties affected are:
- Santa Barbara
- Ventura
- Los Angeles
- Orange
- San Diego.
If you’re planning to enjoy seafood, you still can, just make sure it comes from trusted sources and avoid harvested seashells. Health officials urge the public to choose seafood from reputable local restaurants and certified suppliers that follow strict safety standards. These sources ensure their products are clean, responsibly harvested, and free from toxins that could pose a risk to your health.
