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 Pharmacia & Upjohn Co. The supplemental NADA provides for the use of neomycin sulfate Type A medicated articles to make Type B and Type C medicated feeds for cattle, swine, sheep, and goats in a broader range of concentrations.


This rule is effective July 26, 2000.

End Further Info End Preamble Start Supplemental Information


Pharmacia & Upjohn Co., 7000 Portage Rd., Kalamazoo, MI 49001-0199, has filed a supplemental application to NADA 140-976 that provides for use of Neomix® (neomycin sulfate) Type A medicated articles to make Type B and Type C medicated feeds for cattle, swine, sheep, and goats used for the treatment and control of colibacillosis (bacterial enteritis) caused by Escherichia coli susceptible to neomycin. The supplemental NADA requested that the approved range of concentrations for neomycin Type C medicated feeds of 400 to 1,600 grams per ton (g/ton) be broadened to 250 to 2,250 g/ton. The approved daily dose of 10 milligrams per pound of body weight remains unchanged. The supplemental NADA is approved as of June 28, 2000, and the regulations are amended in 21 CFR 558.364 to reflect the approval.

Approval of this supplemental NADA does not require additional safety and effectiveness data. 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 congressional review requirements in 5 U.S.C. 801-808.
