CFR Citation: 21 CFR Part 558

NOTICE: RULES

ACTION: Animal drugs, feeds, and related products:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: New Animal Drugs for Use in Animal Feeds; Lincomycin

DATES: This rule is effective June 18, 2007.

DOCUMENT SUMMARY: 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., a Div. of Pfizer, Inc. The supplemental NADA provides for the use of lincomycin in feed of swine weighing greater than 250 pounds and for the addition of a reproductive cautionary statement to labeling.

SUMMARY: Lincomycin,

SUPPLEMENTAL INFORMATION

Pharmacia & Upjohn Co., a Div. of Pfizer, Inc., 235 E. 42d St., New York, NY 10017, filed a supplement to NADA 97505 that provides for use of LINCOMIX 20 (lincomycin hydrochloride) and LINCOMIX 50 Feed Medications in singleingredient Type B and Type C medicated feeds for swine weighing greater than 250 pounds and for the addition of a reproductive caution statement to labeling. The supplemental application is approved as of May 23, 2007, and the regulations are amended in 21 CFR 558.325 to reflect the approval.

Approval of this supplemental NADA did not require review of additional safety or effectiveness data or information. 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. 801808.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs and redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is amended as follows:
