New Animal Drugs For Use In Animal Feeds; Nicarbazin, Narasin, and Bacitracin Methylene Disalicylate
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 using approved two-way narasin/nicarbazin and single-ingredient bacitracin methylene disalicylate (BMD) Type A medicated articles to make three-way, combination drug Type C medicated feeds for broiler chickens.
DATES:
This rule is effective May 6, 2002.

Steven D. Vaughn, Center for Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-7580, e-mail: svaughn@cvm.fda.gov.
SUPPLEMENTARY INFORMATION:
Alpharma, Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, has filed NADA 141-124 that provides for the combination use of approved MAXIBAN (36 grams per pound (g/lb) each of narasin and nicarbazin) and BMD (10, 25, 30, 40, 50, 60, or 75 g/lb bacitracin methylene disalicylate) Type A medicated articles in three-way, combination drug Type C medicated feeds for broiler chickens. The Type C feeds containing 27 to 45 g/ton each narasin and nicarbazin and 50 g/ton bacitracin methylene disalicylate are used for the prevention of coccidiosis caused by Eimeria tenella , E. necatrix , E. acervulina , E. maxima , E. brunetti , and E. mivati , and as an aid in the prevention of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin. The Type C broiler feeds containing 27 to 45 g/ton each narasin and nicarbazin and 100 to 200 g/ton BMD are used for the prevention of coccidiosis caused by E. tenella , E. necatrix , E. acervulina , E. maxima , E. brunetti , and E. mivati as an aid in the control of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin. The NADA is approved as of January 14, 2002, and the regulations in 21 CFR 558.76 and 558.366 are amended to reflect the approval. The basis of approval is discussed in the freedom of information summary.
In accordance with the freedom of information provisions of 21 CFR part 20 and 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 Dockets Management Branch (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.
FDA 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.
