Food and Drug Administration

21 CFR Parts 556 and 558


New Animal Drugs; Laidlomycin

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 Alpharma Inc. The supplemental NADA 
provides for the establishment of a tolerance for residues of 
laidlomycin in cattle liver. The previously established acceptable 
daily intake (ADI) for total residues of laidlomycin is also being 
codified.

DATES: This rule is effective July 18, 2003.

FOR FURTHER INFORMATION CONTACT: Eric S. Dubbin, Center for Veterinary 
Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-827-0232, e-mail: [email protected].

SUPPLEMENTARY INFORMATION: Alpharma Inc., One Executive Dr., P.O. Box 
1399, Fort Lee, NJ 07024, filed a supplement to NADA 141-025 for use of 
CATTLYST (laidlomycin propionate potassium) Type A medicated articles 
used to formulate Type C medicated feeds for cattle. The supplemental 
NADA provides for the establishment of a tolerance for residues of 
laidlomycin in cattle livers. FDA is also taking this opportunity to 
codify the previously established ADI for total residues of 
laidlomycin. The supplemental NADA is approved as of May 12, 2003, and 
parts 556 and 558 (21 CFR parts 556 and 558) are amended by adding new 
Sec.  556.346 and by revising Sec.  558.305. 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 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 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)(1) 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.
