More packages of frozen shrimp potentially affected by radioactive contamination have been recalled, federal officials said Thursday.
California-based Southwind Foods recalled frozen shrimp sold under the brands Sand Bar, Arctic Shores, Best Yet, Great American and First Street. The bagged products were distributed between July 17 and Aug. 8 to stores and wholesalers in nine states: Alabama, Arizona, California, Massachusetts, Minnesota, Pennsylvania, Utah, Virginia, and Washington state.
The products have the potential to be contaminated with Cesium-137, a radioactive isotope that is a byproduct of nuclear reactions.
CsCl is also much less active per gram because about half of fission product cesium is stable (on top of longer halflife)
