Red Tide

Contact Us

As red tide blooms approach coastal areas, breaking waves can cause their toxins to become mixed with airborne sea spray. People in coastal areas can experience varying degrees of eye, nose, and throat irritation. When a person leaves an area with a red tide, symptoms usually go away. People with severe or chronic respiratory conditions such as asthma or chronic lung disease are cautioned to avoid areas with active red tides.

Shellfish like clams, oysters, and coquinas that are harvested from areas with active red tides should not be eaten. These shellfish are filter feeders that can concentrate the toxins. Scallops can be consumed if only the scallop muscle is eaten. Scallop stew, using the whole animal including guts, should not be eaten. Seafood, also commonly called shellfish such as crabs, shrimp, and lobster can be eaten because they do not concentrate the toxin.
