The Food and Drug Administration issues a second recall on frozen shrimp after potential exposure to radioactive material.

Southwind Foods, a California-based company, "voluntarily" recalled a select amount of frozen shrimp due to possible contamination with the radioactive isotope cesium-137, the FDA said in a Thursday press release.

This marks the second recall of frozen shrimp this week after both companies' products were potentially exposed to Cesium-137.
