Texas Shellfish Recall Due to Algae Bloom

Texas Shellfish Recall Due to Algae Bloom

If you live in Texas and like to drive to the coast for fresh shellfish, be warned: an algae bloom has closed the bays in Aransas, Corpus Christi and Copano. A recall of oysters, clams and mussels has been issued.

Consumers who purchased or harvested shellfish after March 1 should not eat them and instead dispose of them.

Algae blooms, also known as red tide, produce a toxin called okadaic acid that causes diarrhetic shellfish poisoning (DSP) in humans. Cooking the shellfish does not kill the toxin. Symptoms of DSP include vomiting, diarrhea, nausea and cramping. The symptoms last two to three days and are usually not life threatening, but are definitely unpleasant.
