Summary:

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect revised human food safety warnings or updated pathogen nomenclature on dosage form new animal drug product labeling that have not been codified. The regulations are also being amended to correct the wording of certain other conditions of use, to correct minor errors, and to revise some sections to reflect a current format. These actions are being taken to comply with the Federal Food, Drug, and Cosmetic Act (FD&C Act) and to improve the accuracy and readability of the regulations.

Supplementary information:

FDA has found that the animal drug regulations do not reflect certain human food safety warnings or the scientific nomenclature of pathogens that have been updated on labeling of various dosage form new animal drug products. At this time, the regulations are being amended to reflect approved labeling. The regulations are also being amended to correct the wording of certain other conditions of use and to correct minor errors. As the opportunity has presented itself, some sections have been revised to a current format. These actions are being taken to comply with the FD&C Act and to improve the accuracy and readability of the regulations.

This rule does not meet the definition of “rule” in 5 U.S.C. 804(3)(A) because it is a rule of “particular applicability.” Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.
