21 CFR Part 558


New Animal Drugs For Use In Animal Feeds; Bacitracin Methylene 
Disalicylate, Decoquinate, and Roxarsone

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the

[[Page 38475]]

animal drug regulations to reflect approval of a new animal drug 
application (NADA) filed by Alpharma Inc. The NADA provides for using 
approved bacitracin methylene disalicylate, decoquinate, and roxarsone 
Type A medicated articles to make combination drug Type C medicated 
broiler chicken feeds.

EFFECTIVE DATE: July 17, 1998.

FOR FURTHER INFORMATION CONTACT: Charles J. Andres, Center for 
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1638.

SUPPLEMENTARY INFORMATION: Alpharma Inc., One Executive Dr., P.O. Box 
1399, Fort Lee, NJ 07024, is sponsor of NADA 141-100 that provides for 
combining approved Type A medicated articles containing BMD<Register> 
(10, 25, 30, 40, 50, 60, or 75 grams per pound (g/lb) bacitracin 
methylene disalicylate) with Deccox<Register> (6 percent or 27.2 g/lb 
decoquinate), and 3-Nitro<Register> (45.4, 90, or 227 g/lb roxarsone) 
to make Type C medicated broiler feeds containing 50 g/ton (g/t) 
bacitracin methylene disalicylate, 27.2 g/t decoquinate, and 22.7 to 
45.4 g/t roxarsone. The Type C medicated broiler feeds are used as an 
aid in the prevention of necrotic enteritis, for the prevention of 
coccidiosis, and for increased rate of weight gain, improved feed 
efficiency, and improved pigmentation in broiler chickens. The NADA is 
approved as of June 2, 1998, and the regulations are amended in 21 CFR 
558.76(d)(3) and 558.195(d) by adding new entries, and 558.530(d)(5)(x) 
is revised to reflect the approval. The basis for 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.
    This approval is for use of single ingredient Type A medicated 
articles to make combination drug Type C medicated feeds. One 
ingredient, roxarsone, is a Category II drug as defined in 21 CFR 
558.3(b)(1)(ii). Prior to enactment of the Animal Drug Availability Act 
of 1996 (Pub. L. 104-250) (ADAA), an approved medicated feed 
application (MFA) was required for feed mills to make Type C medicated 
feeds from Type A medicated articles containing Category II drugs. The 
ADAA revised the Federal Food, Drug, and Cosmetic Act to replace the 
requirement for MFA's with a requirement for feed mill licenses.
    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.

    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:
