WASHINGTON — More packages of frozen shrimp potentially affected by radioactive contamination have been recalled, federal officials said Thursday.

Southwind Foods, a company based in California, has recalled frozen shrimp products sold under the brands Sand Bar, Arctic Shores, Best Yet, Great American, and First Street. These products were distributed between July 17 and August 8 to retail outlets and wholesalers across nine states: Alabama, Arizona, California, Massachusetts, Minnesota, Pennsylvania, Utah, Virginia, and Washington.

The products have the potential to be contaminated with Cesium-137, a radioactive isotope that is a byproduct of nuclear reactions.

Walmart stores this week recalled packages of Great Value frozen raw shrimp sold in 13 states because of potential radioactive contamination.

After federal officials discovered Cesium-137 in shipping containers at four U.S. ports and in a sample of frozen breaded shrimp imported by BMS Foods of Indonesia, the U.S. Food and Drug Administration issued a safety alert.

Consumers are advised by the FDA to avoid consuming the recalled shrimp products. While Cesium-137 can be found in various environmental sources like food, soil, and air, it poses a significant health risk with long-term, low-level exposure due to its potential to increase cancer risk.
