Health authorities are urgently advising Americans to inspect their freezers following the discovery of a radioactive element in a widely popular shrimp brand available at Walmart.
The FDA has told the public to avoid Great Value raw frozen shrimp due to contamination with Cesium-137, a radioactive isotope.
Customs and Border Protection officers detected the radioactive isotope Cesium-137, or Cs-137, in shipping containers at four significant US ports, prompting them to alert the FDA.
The FDA conducted tests on the shipping containers’ contents and confirmed on Tuesday that the shrimp, imported from an Indonesian company named BMS Foods, was indeed contaminated.
CBP and the FDA are now working with Indonesian seafood regulators to pinpoint the precise source of the contamination.
According to the agency, evidence suggests the shrimp was processed or stored in unsanitary conditions that likely led to the radioactive contamination, making it unsafe for people to eat.
The risk of contamination from passing a contaminated shipping container is low, but that risk compounds if a person were to eat radioactive shrimp.
Once inside your body, Cs-137 acts as a long-term, internal source of radiation that significantly increases cancer risk.
The Do Not Eat warning is issued out of an abundance of caution, the FDA said, adding that testing to date has not confirmed the presence of contamination in any product currently being sold in stores.
Health regulators are urgently warning Americans to check their freezers after a radioactive substance was found in a popular bag of shrimp sold at Walmart .
The contaminated shipping containers entered the ports of Los Angeles, Houston, Savannah, and Miami.
The containers included three lots of Great Value brand frozen raw shrimp, all with best by dates of March 15, 2027.
The FDA confirmed Cs-137 in one batch of breaded shrimp, but all contaminated shipments were prevented from entering the US.
‘If you have recently purchased raw frozen shrimp from Walmart that matches this description, throw it away,’ the FDA said.
The FDA also instructed distributors and retailers to throw the product away. Anyone who believes they may have eaten it should consult their doctor.
The agency added that it ‘will continue working with industry to trace all implicated products processed by PT. Bahari Makmur Sejati through the supply chain to gather as much information about them as possible and take action as appropriate.’
Low-level exposure to Cs-137 is common for everyone due to its persistent presence in the environment from past nuclear weapons testing in the 1950s and 60s, according to the CDC.
The significant health risk, however, comes from highly concentrated sources found in medical and industrial equipment, where the material is sealed within protective shielding to prevent exposure.
A serious danger emerges if this shielding is compromised, either accidentally or intentionally, allowing the release of the highly concentrated radioactive material.
Significant external exposure to Cs-137 can result in severe health effects, including radiation burns, acute radiation sickness, and death. The high-energy gamma radiation it emits also elevates long-term cancer risk.
If Cs-137 is ingested or inhaled, it disperses throughout the body’s soft tissues, concentrating in the muscles, creating a persistent internal source of radiation.
It bombards surrounding tissues with beta particles and gamma rays, and substantially increases the likelihood of developing cancer.
The level of radiation found in the shrimp is below the official safety limit. However, the FDA is concerned that if someone ate shrimp with this level of radiation regularly for a long time, it could put their health at risk.
