DEPARTMENT OF HEALTH AND HUMAN SERVICES

Food and Drug Administration

21 CFR Part 558

 
New Animal Drugs for Use in Animal Feeds; Bacitracin Methylene 
Disalicylate and Nicarbazin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a new animal drug application 
(NADA) filed by Alpharma, Inc. The NADA provides for use of approved, 
single-ingredient Type A medicated articles containing bacitracin 
methylene disalicylate and nicarbazin to formulate two-way combination 
drug Type C medicated feeds for broiler chickens.

DATES: This rule is effective March 26, 2008.

FOR FURTHER INFORMATION CONTACT: Timothy Schell, Center for Veterinary 
Medicine (HFV-128), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 240-276-8116, e-mail: timothy.schell@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Alpharma, Inc., 440 Rt. 22, Bridgewater, NJ 
08807, filed NADA 141-279 that provides for use of BMD (bacitracin 
methylene disalicylate) and NICARB (nicarbazin) Type A medicated 
articles to formulate two-way combination drug Type C medicated feeds 
for broiler chickens. The NADA is approved as of February 21, 2008, and 
the regulations are amended in 21 CFR 558.366 to reflect the approval.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and 
effectiveness data and information submitted to support approval of 
this application may be seen in the Division of Dockets Management 
(HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, 
Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
    The agency has determined under 21 CFR 25.33(a)(2) that this action 
is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.
    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.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under

redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is 
amended as follows:
