Seattle-based AquaStar (USA) Corp is recalling approximately 26,460 6-ounce packages of cocktail shrimp, imported from Indonesia, and sold between July 31 and Aug. 16.

The states in which they have been sold are Alaska, Alabama, Arkansas, Colorado, Georgia, Iowa, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Michigan, Minnesota, Missouri, Mississippi, Montana, North Dakota, Nebraska, Ohio, Oklahoma, Oregon, South Dakota, Tennessee, Texas, Washington, Wisconsin,

A day earlier, on Aug. 27, the FDA issued a similar recall warning for frozen cooked shrimp sold across 17 states. In that instance, the importer, Aquastar, had recalled approximately 18,000 bags (net weight 2 pounds) of Kroger Mercado Cooked Medium Peeled Tail-Off Shrimp.

Both recalls are an expansion of recent recalls by Walmart and other distributors.

Cs-137 is a man-made radioisotope of the extremely reactive metal cesium, the FDA said.

Traces of Cs-137 are widespread and can be present at higher levels in water or foods grown, raised, or produced in areas with environmental contamination.

Exposure to stable or radioactive Cs-137 happens when an individual ingests contaminated food or liquids, or even breathes in contaminated air, according to the Centers for Disease Control and Prevention.

High levels of radioactive cesium in or near the body can result in nausea, vomiting, diarrhea, bleeding, coma, and death.

The FDA warned that repeated low-dose exposure to Cs-137 through consuming contaminated food can increase the risk of cancer and result in damage to DNA.

The latest Walmart products recalled were sold in refrigerated conditions, have a 12-day shelf life, and have various "Best By" dates, the FDA said.

The 6-ounce batches of cocktail shrimp were packaged in a clear plastic tray and have a red and white label with UPC 19434612191 and lot codes 10662 5106, 10662 5107, 10662 5124, and 10662 5125 printed at the bottom of the tray.
