[Federal Register Volume 64, Number 112 (Friday, June 11, 1999)] [Rules and Regulations] [Pages 31497-31498] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 99-14924] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration 21 CFR Parts 520 and 556 Oral Dosage Form New Animal Drugs; Neomycin Sulfate AGENCY: Food and Drug Administration, HHS. ACTION: Final rule. ----------------------------------------------------------------------- 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. The supplemental NADA provides for use of neomycin sulfate in turkey drinking water for the control of mortality associated with Escherichia coli organisms susceptible to neomycin sulfate in growing turkeys. The regulations are also amended to provide for a tolerance for neomycin residues in edible turkey tissues and an acceptable daily intake (ADI). EFFECTIVE DATE: June 11, 1999. FOR FURTHER INFORMATION CONTACT: William T. Flynn, Center for Veterinary Medicine (HFV-133), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-7570. SUPPLEMENTARY INFORMATION: Pharmacia & Upjohn Co., 7000 Portage Rd., Kalamazoo, MI 49001-0199, filed supplemental NADA 11-315 that provides for use of Neomix325 and Neomix AG 325 (neomycin sulfate) soluble powder in turkey drinking water for the control of mortality associated with E. coli organisms susceptible to neomycin sulfate in growing turkeys. The supplemental NADA is approved as of May 5, 1999, and 21 CFR 520.1484 is amended to reflect the approval. The basis of approval is discussed in the freedom of information summary. In addition, a tolerance for residues of neomycin in edible tissues of turkeys has not been previously established. Section 556.430 is amended editorially to reflect current format, to provide tolerances for neomycin residues in edible turkey tissue, and to provide an ADI for neomycin. In accordance with the freedom of information provisions of 21 CFR part 20 and 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this supplemental application may be seen in the Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday. Under section 512(c)(2)(F)(iii) of the Federal, Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval for use in turkey drinking water qualifies for 3 years of marketing exclusivity beginning May 5, 1999, because the supplemental application contains substantial evidence of the effectiveness of the drug involved, any studies of animal safety or, in the case of food- producing animals, human food safety studies (other than bioequivalence or residue studies) required for this approval and conducted or sponsored by the applicant. The 3 years marketing exclusivity is limited to use of the drug for the control of mortality associated with E. coli organisms susceptible to neomycin sulfate in growing turkeys. FDA has carefully considered the potential environmental effects of this action and has concluded that the action will not have a significant impact on the human environment. Therefore, an environmental impact statement is not required. FDA's finding of no significant impact and the evidence supporting that finding, contained in an environmental assessment, may be seen in the Dockets Management Branch (address above) between 9 a.m. and 4 p.m., Monday through Friday. 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. List of Subjects 21 CFR Part 520 Animal drugs. 21 CFR Part 556 Animal drugs, Foods. 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 parts 520 and 556 are amended as follows: PART 520--ORAL DOSAGE FORM NEW ANIMAL DRUGS 1.

(a) Specifications. Neomycin sulfate soluble powder contains 20.3 grams of neomycin sulfate (equivalent to 14.2 grams of neomycin base) per ounce. (b) Sponsors. See 000069, 046573, 050604, and 051259 in Sec. 510.600(c) of this chapter for use as in paragraph (d)(1) of this section. See 000009 for use as in paragraphs (d)(1) and (d)(2) of this section. (c) Related tolerances. See Sec. 556.430 of this chapter. (d) Conditions of use-(1) Cattle (excluding veal calves), swine, sheep, and goats. (i) Amount. 10 milligrams of neomycin sulfate per pound of body weight per day (22 milligrams per kilogram) in divided doses for a maximum of 14 days. (ii) Indications for use. For the treatment and control of colibacillosis (bacterial enteritis) caused by Escherichia coli susceptible to neomycin sulfate in cattle (excluding veal calves), swine, sheep, and goats. (iii) Limitations. Add to drinking water or milk; not for use in liquid supplements. Prepare a fresh solution daily. If symptoms persist after using this preparation for 2 or 3 days, consult a veterinarian. Treatment should continue 24 to 48 hours beyond remission of disease symptoms, but not to exceed a total of 14 consecutive days. Discontinue treatment prior to slaughter as follows: Cattle (not for use in veal calves), 1 day; sheep, 2 days; swine and goats, 3 days. (2) Turkeys-(i) Amount. 10 milligrams of neomycin sulfate per pound of body weight per day (22 milligrams per kilogram) for 5 days. (ii) Indications for use. For the control of mortality associated with E. coli organisms susceptible to neomycin sulfate in growing turkeys. (iii) Limitations. Add to drinking water; not for use in liquid supplements. Prepare a fresh solution daily. If symptoms persist after using this preparation for 2 or 3 days, consult a veterinarian. Treatment should continue 24 to 48 hours beyond remission of disease symptoms, but not to exceed a total of 5 consecutive days. PART 556--TOLERANCES FOR RESIDUES OF NEW ANIMAL DRUGS IN FOOD 3.

(2) Turkeys. 7.2 ppm in skin with adhearing fat, 3.6 ppm in liver, and 1.2 ppm in muscle. (3) Milk. A tolerance is established for residues of parent neomycin of 0.15 ppm. Dated: May 28, 1999.
