21 CFR Parts 520 and 522

[Docket No. FDA-2011-N-0003]


New Animal Drugs; Ampicillin Trihydrate, Bacitracin Methylene 
Disalicylate, Flunixin, Gonadotropin Releasing Factor Analog-Diphtheria 
Toxoid Conjugate, Methylprednisolone, and Sulfamethazine

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; correcting amendments.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect revised human food safety warnings 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 
(the FD&C Act) and to improve the accuracy and readability of the 
regulations.

DATES: This rule is effective August 25, 2011.

FOR FURTHER INFORMATION CONTACT: George K. Haibel, Center for 
Veterinary Medicine (HFV-6), Food and Drug Administration, 7519 
Standish Pl., Rockville, MD 20855, 240-276-9019, e-mail: 
george.haibel@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: FDA has found that the animal drug 
regulations do not reflect certain human food safety warnings 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.
