21 CFR Part 558

 
New Animal Drugs for Use in Animal Feed; Zilpaterol

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 Intervet, Inc. The NADA provides for use of approved, 
single-ingredient zilpaterol hydrochloride and monensin U.S.P. Type A 
medicated articles to make two-way combination Type B and Type C 
medicated feeds for cattle fed in confinement for slaughter.

DATES: This rule is effective March 18, 2008.

FOR FURTHER INFORMATION CONTACT:  Gerald L. Rushin, Center for 
Veterinary Medicine (HFV-126), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8103, e-mail: 
gerald.rushin@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Intervet, Inc., P.O. Box 318, 29160 Intervet 
Lane, Millsboro, DE 19966, filed NADA 141-278 that provides for use of 
ZILMAX (zilpaterol hydrochloride) and RUMENSIN (monensin U.S.P.) Type A 
medicated articles to make dry and liquid, two-way combination Type B 
and Type C medicated feeds used for increased rate of weight gain, 
improved feed efficiency, and increased carcass leanness; and for 
prevention and control of coccidiosis due to Eimeria bovis and E. 
zuernii in cattle fed in confinement for slaughter during the last 20 
to 40 days on feed. The NADA is approved as of February 15, 2008, and 
the regulations in 21 CFR 558.665 are amended 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 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.
