The U.S. Food and Drug Administration is expanding its warning about radioactive shrimp, recalling more brands due to possible contamination.
The federal health agency said earlier this week nearly 18,000 bags of frozen Kroger Mercado Cooked Medium Peeled Tail-Off Shrimp and 26,460 packages of cocktail shrimp, both from Seattle-based Aquastar Corp, were recalled because of potential contamination with the radioactive isotope Cesium-137 (Cs-137).
Earlier alerts had warned about contamination among Walmart’s Great Value shrimp and frozen shrimp sold by California-based company Southwind Foods.

The FDA said all of the brands were processed by the Indonesian supplier PT. Bahari Makmur Sejati, operating as BMS Foods, and the company has been placed under a full import alert.
PT. Bahari Makmur Sejati was added “to a new import alert for chemical contamination to stop products from this firm from coming into the U.S. until the firm has resolved the conditions that gave rise to the appearance of the violation,” the FDA said in a press release.
The shrimp placed under recall alerts may have been prepared, packed or held in “insanitary conditions” during which they became contaminated with Cs-137, the FDA said.

No products have tested positive for Cs-137 in the U.S. marketplace at this time, and no illnesses have been reported to date, according to the FDA.
Cesium is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder, according to the U.S. Environmental Protection Agency.
Low-dose exposure to Cs-137, such as in water or food, over a long-term period of time can damage DNA within living cells of the body and increase the risk of cancer, the FDA says.
External exposure to large amounts of Cs-137, according to the EPA, can cause burns, acute radiation sickness and even death.
