AGENCY:

Food and Drug Administration, HHS.

ACTION:

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: [e-mail].

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.

List of Subjects in 21 CFR Part 558

• Animal drugs
• Animal feeds

Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs and redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is amended as follows:
