21 CFR Part 558

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


New Animal Drugs for Use in Animal Feeds; Monensin; Tylosin

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 supplemental new animal drug 
application (NADA) filed by Elanco Animal Health, A Division of Eli 
Lilly & Co. The supplemental NADA revises limitations for liquid Type B 
medicated cattle feeds containing tylosin phosphate.

DATES: This rule is effective October 15, 2009.

FOR FURTHER INFORMATION CONTACT: Cindy L. Burnsteel, Center for 
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 240-276-8341, e-mail: 
<a href="/cdn-cgi/l/email-protection#beddd7d0dac790dccbccd0cdcadbdbd2fed8dadf90d6d6cd90d9d1c8"><span class="__cf_email__" data-cfemail="3f5c56515b46115d4a4d514c4b5a5a537f595b5e1157574c11585049">[email protected]</span></a>.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli 
Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a 
supplement to NADA 12-491 for use of TYLAN (tylosin phosphate) Type A 
medicated article. For liquid Type B medicated cattle feeds containing 
tylosin phosphate, the supplement removes the presolubilization 
instructions previously required for manufacture and reduces the expiry 
from 8 weeks to 31 days. The supplemental NADA is approved as of 
September 8, 2009, and the regulations in 21 CFR 558.625 are amended to 
reflect the approval. In addition, the limitations for two-way 
combination drug medicated liquid feeds containing tylosin and monensin 
in 21 CFR 558.355 are amended to reflect the revised limitations for 
tylosin liquid feeds.
    Approval of this supplemental NADA did not require review of 
additional safety or effectiveness data or information. Therefore, a 
freedom of information summary is not required.
    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.
