Still, considering that Robert F. Kennedy, Jr., the anti-vaxxer in charge of the Department of Health and Human Services that oversees the FDA, once ate so much tuna and perch fish that it gave him mercury poisoning, it seems unlikely that the agency is going to put that much effort into warning people not to consume potentially radioactive shrimp.
Just be sure to take your iodine tablets and you can have a little radioactive shrimp, as a treat.
