how did the shrimp get radioactive

The shrimp became radioactive due to contamination by cesium-137, a radioactive isotope. This contamination was linked to shrimp imported from Indonesia, specifically processed by a company called PT Bahari Makmur Sejati (also operating as BMS Foods). The radioactive cesium-137 was detected in shipping containers and some shrimp samples. The contamination likely occurred because the shrimp were stored or processed in unsanitary conditions that allowed exposure to cesium-137. This isotope is a byproduct of nuclear fission and can cause DNA damage and increase cancer risks if ingested over time. The Indonesian government is investigating the source of contamination, and U.S. authorities have halted imports from the implicated company until the issue is resolved. No radioactive shrimp have been confirmed to have entered U.S. stores, and no illnesses have been reported so far.
