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 Schering-Plough Animal Health Corp. The NADA provides for use of a florfenicol concentrate solution to make medicated drinking water for administration to swine for the treatment of respiratory disease. FDA is also amending the regulations to add tolerances for residues of florfenicol in edible tissues of swine.
DATES:
This rule is effective December 24, 2002.
FOR FURTHER INFORMATION CONTACT:
Joan C. Gotthardt, Center for Veterinary Medicine (HFV-130), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-7571, e-mail: jgotthar@cvm.fda.gov.
SUPPLEMENTARY INFORMATION:
Schering-Plough Animal Health Corp., 1095 Morris Ave., Union, NJ 07083, filed NADA 141-206 for NUFLOR (florfenicol) 2.3% Concentrate Solution used to make medicated drinking water for administration to swine for the treatment of respiratory disease associated with several bacterial pathogens. The NADA is approved as of September 4, 2002, and the regulations are amended in 21 CFR part 520 by adding § 520.955 to reflect the approval. The basis of approval is discussed in the freedom of information summary.
In addition, the regulations are amended in 21 CFR 556.283 to establish tolerances for residues of florfenicol in edible tissues of treated swine and to reflect a current format.
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.
Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 3 years of marketing exclusivity beginning September 4, 2002.
The agency has determined under 21 CFR 25.33(d)(5) 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.
