Final rule.


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 Fort Dodge Animal Health. The supplemental NADA provides for amending the milk discard statement to state the milk discard time only (i.e., to remove reference to the number of milkings).


This rule is effective April 18, 2000.

End Further Info End Preamble Start Supplemental Information


Fort Dodge Animal Health, Division of American Home Products Corp., 800 Fifth Street NW., P.O. Box 518, Fort Dodge, IA 50501, filed supplemental NADA 97-222 that provides for a 96-hour milk-discard time (i.e., removal of the parenthetical reference to an 8-milking milk discard time) for use of CEFA-LAK® and TODAY® (cephapirin sodium) intramammary infusion products for treatment of lactating cows for bovine mastitis. The supplemental NADA is approved as of February 4, 2000, and the regulations are amended in 21 CFR 526.365(d)(3) to reflect the approval.

Approval of this supplemental NADA conforms to the requirements of 21 CFR 510.105. Approval does not require review of the safety or effectiveness data required for approval of the NADA. Therefore, a freedom of information summary is not required.

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.
