Start Preamble


Food and Drug Administration, HHS.


Final rule; technical amendment.


The Food and Drug Administration (FDA) is amending the animal drug regulations that reflect approval of two new animal drug applications (NADAs) for combination drug Type C feeds containing nequinate. In a notice published in the Federal Register of February 28, 1978 (43 FR 8182), FDA withdrew approval of these NADAs. This action is being taken to improve the accuracy of the regulations.


This rule is effective August 28, 2001.

End Further Info End Preamble Start Supplemental Information


In the Federal Register of February 28, 1978 (43 FR 8182), the agency published a notice that it was withdrawing approval of NADA 42-919 for combination use of nequinate and roxarsone, and NADA 48-205 for combination use of nequinate and oxytetracycline, both in chicken feed. These actions were requested by the sponsor, Ayerst Laboratories, because the products were no longer manufactured or marketed. However, a final rule published in the same issue of the Federal Register (43 FR 8134) did not amend all applicable portions of the regulations. At this time, the agency is amending the animal drug regulations in 21 CFR 558.365 and 558.450 to remove portions reflecting approval of these NADA’s.

Publication of this document constitutes final action on these changes under the Administrative Procedure Act (5 U.S.C. 553). Notice and public procedure are unnecessary because FDA is merely making nonsubstantive changes.

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.
