How the hell did Cs137 get into the shrimp?!
In any case, this is about one shipping container with a really low dose that never made it to the food chain, that we know of so far:
The level of Cs-137 detected in the detained shipment was approximately 68 Bq/kg, which is below FDA’s Derived Intervention Level for Cs-137 of 1200 Bq/kg.
