21 CFR Part 558

[Docket No. FDA-2009-N-0665]


New Animal Drugs for Use in Animal Feeds; Semduramicin; 
Virginiamycin

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 an original new animal drug 
application (NADA) filed by Phibro Animal Health. The NADA provides for 
use of single-ingredient Type A medicated articles containing 
semduramyicin (as semduramicin sodium biomass) and virginiamycin to 
manufacture 2-way combination drug Type C medicated feeds for use in 
broiler chickens.

DATES: This rule is effective August 18, 2009.

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: [email protected].

SUPPLEMENTARY INFORMATION: Phibro Animal Health, 65 Challenger Rd., 3d 
floor, Ridgefield Park, NJ 07660, filed NADA 141-289 that provides for 
the use of AVIAX II (semduramicin sodium biomass) and STAFAC 
(virginiamycin) Type A medicated articles to manufacture 2-way 
combination drug Type C medicated feeds for broiler chickens. The NADA 
is approved as of July 13, 2009, and the regulations are amended in 21 
CFR 558.555 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 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.
