More bagged, frozen shrimp are part of another recall issued by the U.S. Food and Drug Administration (FDA) on Aug. 21. This recall affects 13 products that may have also been contaminated with radioactive isotope Cesium-137 across nine states.

Some packages of Great Value frozen shrimp sold at Walmart are at risk for potential for Cesium-137 contamination, the FDA says.

The FDA advises consumers not to eat the recalled products. Traces of Cesium-137 are widespread in the environment including food, soil and air. The primary health risk is through long-term, repeated low-dose exposure, which can increase the risk of cancer.
