Start Preamble


Food and Drug Administration, HHS.


Final rule.


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 lasalocid and bacitracin methylene disalicylate Type A medicated articles to make two-way combination drug Type C medicated feeds. These combination medicated feeds are used for the prevention of coccidiosis, and for increased rate of weight gain and improved feed efficiency in growing turkeys.


This rule is effective September 5, 2001.

Alpharma, Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, filed NADA 141-179 that provides for use of AVATEC® (90.7 grams per pound (g/lb) of lasalocid sodium) and BMD® (50 g/lb of bacitracin methylene disalicylate) Type A medicated articles to make combination drug Type C medicated turkey feeds. The combination Type C medicated feeds are used for prevention of coccidiosis caused by Eimeria meleagrimitis, E. gallopavonis, E. adenoeides, and for increased rate of weight gain and improved feed efficiency in growing turkeys. The NADA is approved as of July 11, 2001, and the regulations are amended in 21 CFR 558.311 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.

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.
