California—A Shrimp News Question on the Radiation of Live Shrimp


In the first week of April 2014, the Food and Drug Administration (FDA) approved the radiation of crustaceans—shrimp, crab and lobster—to control pathogens and extend shelf life.  The new rule covers raw, frozen, cooked, partially cooked, shelled, dried and ready-to-cook crustaceans.


In his report on FDA’s approval, John Sackton, editor and publisher of, an online, subscription-based, fisheries news service, mentioned that Crystal Seas Oysters, which fishes, processes and markets oysters, radiates live, in-shell oysters.  Crystal Seas’ webpage says the radiation treatment eliminates Vibrios to undetectable levels in live oysters.  The temperature of the oysters does not change during the radiation process.


Does anyone know if live shrimp broodstock and postlarvae could be radiated to eliminate Vibrios and possibly EMS?  Presumably, the shrimp produced from the process would not need to carry the radiation symbol, especially if only the broodstock were radiated.
