21 CFR Part 520


Oral Dosage Form New Animal Drugs; Neomycin Sulfate Oral Solution

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 abbreviated new 
animal drug application (ANADA) filed by Pharmacia & Upjohn Co. The 
supplemental ANADA provides for a shorter withdrawal period following 
use of neomycin sulfate oral solution in the drinking water or in milk 
for cattle (excluding veal calves), swine, sheep, and goats for the 
treatment and control of colibacillosis.

EFFECTIVE DATE: November 12, 1997.

FOR FURTHER INFORMATION CONTACT: Lonnie W. Luther, Center for 
Veterinary Medicine (HFV-102), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-0209.

SUPPLEMENTARY INFORMATION: Pharmacia & Upjohn Co., 7000 Portage Rd., 
Kalamazoo, MI 49001-0199, filed supplemental ANADA 200-113 that 
provides for a shorter withdrawal period following use of neomycin 
sulfate oral solution in the drinking water or in milk for cattle 
(excluding veal calves), swine, sheep, and goats for the treatment and 
control of colibacillosis (bacterial enteritis) caused by Escherichia 
coli susceptible to neomycin sulfate.
    Approval of supplemental ANADA 200-113 is as a generic copy of the 
sponsor's approved supplemental NADA 11-315. The supplemental ANADA is 
approved as of February 7, 1997, and the regulations are amended in 
Sec. 520.1485(d)(3) (21 CFR 520.1485(d)(3)) to reflect the approval.
    The previously approved supplement to NADA 11-315 included data to 
support revised tolerances for residues of neomycin in the edible 
tissues of cattle, swine, sheep, and goats. Based on evaluation of the 
data as provided in the ``General Principles for Evaluating the Safety 
of Compounds Used in Food-Producing Animals Guidelines,'' tolerances of 
1.2 parts per million (ppm) in muscle, 3.6 ppm in liver, and 7.2 ppm in 
kidney and fat, and withdrawal times of 1 day for cattle, 2 days for 
sheep, and 3 days for swine and goats were established. The revised 
withdrawal times were established in 21

CFR 520.1484(c)(3) and now for ANADA 200-113 in Sec. 520.1485(d)(3).
    No additional effectiveness or safety studies were required for 
this approval. Therefore, a freedom of information summary is not 
required. A summary of data and information submitted to support the 
original ANADA approval may be seen in the Dockets Management Branch 
(HFA-305), Food and Drug Administration, 12420 Parklawn Dr., rm. 1-23, 
Rockville, MD 20857, between 9 a.m. and 4 p.m., Monday through Friday.
    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.

List of Subjects in 21 CFR Part 520

    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 520 is 
amended as follows:
