The U.S. Food and Drug Administration (FDA) has issued a final rule denying requests for a stay of the effective date and for a hearing on the final rule concerning the use of irradiation in food production, processing and  handling. Originally appearing in the August 22, 2008, Federal Register, the  rule amended food additive regulations to permit the use of ionizing radiation to control food-borne pathogens and extend the shelf life of fresh iceberg lettuce and spinach.

After reviewing objections to the final rule and requests for a hearing, FDA has concluded that “the objections do not raise issues of material fact that justify  a hearing or otherwise provide a basis for revoking or modifying the amend- ment to the regulation,” and confirmed August 22, 2008, as the effective date for the final rule.
