Start Preamble


Food and Drug Administration, HHS.


Final rule; technical amendment.


The Food and Drug Administration (FDA) is updating the animal drug regulations to correctly reflect a previously approved 227 grams per pound (g/lb) strength of penicillin G Type A medicated article for use in the feed of several domestic species which was omitted from the regulation in the 1998 notice of approval.


This rule is effective July 26, 2000.

End Further Info End Preamble Start Supplemental Information


Pfizer, Inc., 235 East 42d St., New York, NY 10017-5755, is sponsor of NADA 046-668 that provides for use of Penicillin 100 (100 g/lb penicillin G procaine) and Penicillin 50 (227 g/lb penicillin G procaine) Type A medicated articles to make Type C medicated feeds used for increased rate of weight gain and improved feed efficiency in poultry and swine. In its approval letter of April 10, 1998, to Pfizer, Inc., the Center for Veterinary Medicine approved the use of these products to make Type C medicated feeds, but did not codify the approval of the 227 g/lb strength of Type A medicated article for this sponsor (63 FR 36179, July 2, 1998). At this time, 21 CFR 558.460(b) is amended by adding the 227 g/lb strength of Type A medicated article to reflect the 1998 approval.

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.
