Ionizing Radiation Now Approved for Shell Eggs.
The extent to which this process eliminates Salmonella in eggs will depend on the Salmonella levels in individual eggs and the dose that is absorbed by each egg. At doses likely to be practical, Salmonella levels may be reduced 10- to 10,000-fold, depending on the distance of the egg from the radiation source. It is unlikely that a 5-log reduction would be achieved by this process alone. Elimination of Salmonella in all eggs cannot be guaranteed--at least on the basis of current knowledge--but the total level of Salmonella in eggs will decrease substantially, and the fraction of eggs containing viable Salmonella also should decrease.
FDA's final rule amending the food additive regulations to allow safe use of ionizing radiation for the reduction of Salmonella in fresh shell eggs was published in the Federal Register of July 21, 2000. The irradiated eggs must be labeled in accordance with the Code of Federal Regulations (21 C.F.R, 179.26).
