The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future.

Food and Drug Administration, HHS.

The application seeks conditional approval of the use of florfenicol by veterinary feed directive for the control of mortality in catfish due to columnaris disease associated with Flavobacterium columnare.
This rule is effective October 9, 2007.Start Further Info

Schering-Plough Animal Health Corp., 556 Morris Ave., Summit, NJ 07901, filed an application for conditional approval (141-259) that provides for the use of AQUAFLOR-CA1 (florfenicol), a Type A medicated article, by veterinary feed directive to formulate Type C medicated feed for the control of mortality in catfish due to columnaris disease associated with Flavobacterium columnare. In accordance with the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Minor Use and Minor Species Animal Health Act of 2004 (MUMS Act), this drug is conditionally approved as of April 13, 2007, and the regulations are amended by adding 21 CFR 516.1215 and by revising 21 CFR 556.283 to reflect the conditional approval of this application. The effect of this final rule is delayed until October 9, 2007, pending establishment of part 516 (72 FR 41010, July 26, 2007).
In accordance with the freedom of information provisions of 21 CFR part 20, a summary of safety and effectiveness data and information submitted to support conditional approval of this application for conditional approval may be seen in the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, Start Printed Page 57200MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
AQUAFLOR-CA1 in the dosage form and for the intended uses conditionally approved by FDA under application number 141-259 qualifies for 7 years of exclusive marketing rights beginning on the date of approval. This new animal drug qualifies for exclusive marketing rights under section 573(c) of the act (21 U.S.C. 360ccc-2(c)) because it has been declared a designated new animal drug by FDA under section 573(a) of the act.
FDA has determined under 21 CFR 25.33(d)(4) 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.Start List of Subjects

(iii) Limitations. Feed containing florfenicol shall not be fed to catfish for more than 10 days. Following administration, fish should be reevaluated by a licensed veterinarian before initiating a further course of therapy. A dose-related decrease in hematopoietic/lymphopoietic tissue may occur.
