I'd be far more concerned if they
weren't radioactive, given that the only way
that can happen is if they're over 80 years old and stored in a sealed container to avoid fallout from nuclear weapons testing, which has contaminated literally everything on Earth since then. And that's not even counting naturally-occurring radioactive materials released into the environment by industrial processes such as mining. Given all the fear-mongering around low-level radiation, I can't even pretend to be concerned by this radioactive shrimp until I know how it compares to
bananas.
EDIT: Found a more useful source for this story:
edition.cnn.com/2025/08/19/health/radioactive-contamination-shrimp-walmart-fdaThe levels of cesium detected – about 68 becquerels per kilogram – were well below the FDA’s intervention level of 1,200 Bq/kg. Still, regulators issued the advisory out of caution, citing the potential risks of cancer from long-term, low-dose exposure and problems at the supplier’s facility.
68 becquerels per kilogram is only 4.5 bananas per kilogram - nothing to panic about and certainly not indicative of a major nuclear whoopsie.
