Shellfish in Antigua & Barbuda: What to Know, What to Watch For, and How Fishermen Protect Public Health

Shellfish such as conch, mussels, oysters, clams, whelks, and periwinkles are an important part of Caribbean cuisine and coastal life. In Antigua & Barbuda, these species contribute to food security, livelihoods, and cultural traditions. However, shellfish also require special care because they can pose health risks if harvested or handled improperly.

Understanding shellfish safety protects consumers, fishermen, and our marine environment.

What Makes Shellfish Different?

Shellfish are filter feeders, meaning they feed by filtering large amounts of water. While this helps keep oceans clean, it also means shellfish can accumulate harmful substances, including:
• Bacteria and viruses
• Harmful algae toxins (red tide)
• Heavy metals and pollutants

Because of this, shellfish must be harvested from clean, monitored waters and handled correctly.
