California Officials Issue Shellfish Warning Due to Toxic Algal Blooms

Statewide Shellfish Quarantine

• ⚠️ California health officials have issued a statewide quarantine on recreationally harvested mussels.
• 📌 An expanded advisory warns against sport-harvested clams, scallops, and oysters from Santa Barbara to San Diego.

Toxic Algal Blooms and Marine Life

• 🌊 A toxic algae bloom is poisoning sea life, leading to a spike in animal deaths, including sea lions and whales.
• 🔬 The toxin, known as domoic acid, builds up in shellfish and enters the food chain.
• 🐟 This toxin affects marine mammals and birds that consume contaminated fish.

Risks to Human Health

• 🧠 The toxin can cause severe or even fatal illness in humans, including Paralytic Shellfish Poisoning.
• ⚡ Symptoms can range from neurological problems to short-term memory loss and, in severe cases, death.
• 🚫 The threat is from beaches where foragers gather shellfish, not from commercially sold, certified sources.

Commercial vs. Recreational Shellfish

• ✅ Commercially sold shellfish from certified sources are considered safe.
• 🎣 The quarantine specifically impacts shellfish caught recreationally and is in effect through October.
• ❓ Officials advise against consuming any questionable shellfish and direct people to websites for updates.
