Radioactive Contamination Found in Imported Shrimp

Food recalls are nothing new, but every so often, one comes along that stands out because of how unusual—and alarming—it is. Most people expect to hear about Salmonella, Listeria, or E. coli when products are pulled from shelves. But radioactive contamination? That’s something far less common and far more unsettling.

In the United States, several well-known seafood companies are now recalling frozen shrimp after federal health officials discovered potential contamination with Caesium-137 (Cs-137), a radioactive isotope linked to cancer.

Southwind Foods, a California-based supplier, is among the companies announcing what they describe as a “limited quantity” recall. Other brands connected to the recall include Sand Bar, Best Yet, Arctic Shores Seafood Company, Great American Seafood Imports Co., and First Street.

The U.S. Food and Drug Administration (FDA) confirmed that the affected shrimp were distributed across multiple states between July 17 and August 8. States include Alabama, Arizona, California, Massachusetts, Minnesota, Pennsylvania, Utah, Virginia, and Washington.

At this stage, the FDA hasn’t identified which retailers sold the shrimp or exactly how the contamination occurred. Consumers who purchased frozen shrimp from these brands during the specified dates are advised to dispose of the products immediately.

FDA Blocks Indonesian Shrimp Shipment After Radioactive Contamination Concerns

This recall comes on the heels of another incident. Just weeks earlier, the FDA flagged raw prawns imported from PT. Bahari Makmur Sejati, a seafood supplier based in Indonesia. That shipment, destined for major U.S. ports in Los Angeles, Houston, Savannah, and Miami, was stopped before it reached store shelves.

The reason? Testing suggested the prawns may have been exposed to Cs-137 while being transported. The agency reported a contamination level of about 68 becquerels per kilogram—below the threshold for immediate harm but concerning enough to block the shipment.

Officials stressed that while no illnesses have been linked to any of the recalled shrimp, repeated exposure to low doses of Cs-137 carries long-term risks. The isotope can damage DNA inside human cells, which over time increases the risk of cancer.

Shrimp Recall Sparks Concern After Discovery of Radioactive Contamination

Most people associate radioactive materials with nuclear plants or old weapons tests, not frozen shrimp at the grocery store. That’s why experts say this case is so unusual.

“This is very, very unique, in my initial reading of the situation,” said Suresh Pillai, a microbiologist who directs the National Center for Electron Beam Research at Texas A&M University, in an interview with Slate.“This is not normal.” He added that it’s more accurate to describe the situation as “shrimp tainted with a material that is radioactive” rather than the catchier but misleading label of “radioactive shrimp.”Unsplash

Caesium-137 is not some obscure lab chemical. According to the Centers for Disease Control and Prevention (CDC), it has widespread industrial and medical uses. It plays a role in radiation therapy to treat certain cancers, in sterilizing medical equipment, and in industrial gauges that measure the flow of liquids through pipelines.

Cs-137 has also been a lingering environmental concern since the mid-20th century. Nuclear weapons testing during the 1950s and 1960s released large amounts into the atmosphere. As a result, trace levels can still be detected worldwide.

Furthermore, the 'availability heuristic,' a concept explored by Dr. Jonathan Haidt, a social psychologist, may also play a part in our reactions to food recalls. Dr. Haidt states, "Our intuitions about risk are often shaped by the stories we hear and the examples we see." This heuristic refers to the mental shortcut that our brains use to make decisions based on the most readily available information. When news of a food recall is widespread, it becomes highly available in our minds, and we may overestimate the probability of being affected by it. As noted by Dr. Angela Duckworth, a character researcher, "We tend to focus on the most dramatic events, which can distort our understanding of everyday risks."

Radiation Exposure Risks Range from Mild to Severe, with Larger Amounts Causing Burns, Sickness, Cancer, or Even Death

For most people, daily exposure to small amounts in the environment isn’t a health issue. But ingestion or inhalation of larger amounts is dangerous.

The CDC notes that symptoms of acute exposure can include burns, nausea, radiation sickness, and, in extreme cases, death. Even without immediate illness, internal contamination raises the risk of long-term health problems like cancer.

Understanding the Psychology of Fear in Food Contamination

The most important step for consumers is vigilance. Anyone who purchased shrimp from the affected brands during the dates listed by the FDA should not eat them. The safest course of action is disposal.

While no illnesses have been reported, the recalls show how fragile the global food supply chain can be. Seafood often travels thousands of miles from fishing boats to American dinner tables, and along the way, it can encounter unexpected risks, from bacterial outbreaks to, in this case, radioactive contamination.

Food safety officials stress that cases like this are rare. Still, the idea of shrimp carrying radioactive particles is enough to unsettle even the most adventurous eater. Whether this turns out to be a one-off shipping error or something more systematic remains to be seen.
