More shrimp recalled for possible radioactive contamination. See full list.

The Food and Drug Administration has issued an expanded warning about more frozen shrimp sold at retailers like Walmart and Kroger for possible radioactive chemical contamination.

The FDA initiated the first recall in an Aug. 19 notice, announcing certain raw frozen shrimp products processed by Indonesian company PT. Bahari Makmur Sejati (doing business as BMS Foods) had tested positive for Cesium-137, also known as Cs-137. A handful of manufacturers sold these products under different brand names to retailers nationwide.

The recall has since been expanded on eight occasions, with the most recent additions being released on Tuesday, Sept. 23, as involved companies continue to add more products to the list.

The presence of Cs-137 violates the Federal Food, Drug, and Cosmetic Act, according to the FDA, which adds that, as it appears, the affected product may have been "prepared, packed, or held under insanitary conditions whereby it may have become contaminated with Cs-137 and may pose a safety concern."

Here's what to know about the latest update on the recalls.

Which shrimp products have been added to the latest recall?

Two companies have added to the recalled shrimp list as of Tuesday, Sept. 23: Southwind Foods LLC, which expanded on a previous recall notice from late August, and Lawrence Wholesale LLC, which sells Kroger-branded products.

Southwind Foods, Beaver Street Fisheries, AquaStar (USA) Corp and Lawrence Wholesale have all issued a series of recalls since Aug. 19 covering shrimp products sold nationwide and processed by PT. Bahari Makmur Sejati.

As of Thursday, Sept. 25, here is the full list.

What is Cesium-137 (Cs-137) and why is it regulated?

Cs-137 is a radioisotope of cesium, meaning it is a chemical element that emits radiation as it breaks down. It is man-made and is produced by nuclear fission, according to the FDA. In the United States, it is used in medical devices and measurement gauges, such as industrial devices that measure the thickness of materials.

Because it is widespread around the globe, trace amounts can be found in the environment, including soil, food and air, the FDA said. Agencies, including the FDA and U.S. Customs & Border Protection, test for, monitor and regulate the presence of the substance due to the risks associated with long-term exposure.

The FDA said low-level radiation exposure over time can lead to serious health complications. Exposure to Cs-137 alone can cause burns, acute radiation sickness, cancer and death. Due to the risks, governing agencies restrict potential exposure to lessen the possibility of these long-term impacts.

PT. Bahari Makmur Sejati has been placed on an import alert, which prevents any of their food products from entering the United States until the company resolves any conditions that could have caused the exposure.

What to do if you have recalled shrimp

If you have a package of the recalled shrimp at home, throw it out and do not eat or serve it, according to the FDA. Distributors and retailers should dispose of the product, not sell or serve it.

Those who fear they may have been exposed to elevated levels of cesium should contact their medical provider. To file a complaint or report an adverse reaction, consumers can visit the FDA's Industry and Consumer Assistance portal.
