[Docket No. FDA-1999-F-2405] (formerly 1999F-5522)
Irradiation in the Production, Processing and Handling of Food
ACTION: Final rule.
..........
SUMMARY: The Food and Drug Administration (FDA) is amending the food additive regulations to provide for the safe use of ionizing radiation for control of food-borne pathogens, and extension of shelf-life, in fresh iceberg lettuce and fresh spinach (hereinafter referred to in this document as ``iceberg lettuce and spinach'') at a dose up to 4.0 kiloGray (kGy).
...........
Based on the totality of the evidence, FDA concludes that irradiation of iceberg lettuce and spinach under the conditions proposed in this petition does not present a toxicological hazard.
..........
Toxicological Considerations
The available information from the results of chemical reactions described in section II.A of this document
suggests that there is no reason to suspect a toxicological hazard due to consumption of an irradiated food.
