III. HUMAN S AFETY
Tolerances for the Marker Residue
The tolerances established for the pioneer bacitracin zinc product apply to the generic bacitracin zinc product.
The tolerances for residues of bacitracin from bacitracin zinc are established at 0.5 ppm (0.02 unit per gram), negligible residue, in uncooked edible tissues of chickens (21 CFR §556.70).
The tolerances for residues of decoquinate are established in uncooked edible tissues of chickens at 2.0 ppm in tissues other than skeletal muscle and 1.0 ppm in skeletal muscle.
Based on the information in 21 CFR §558.195(d), a withdrawal time is not required for the use of the combination of bacitracin and decoquinate in broiler chickens.
Regulatory Method for Residues
The regulatory analytical method for detection of residues of bacitracin is a microbiological test using Sarcina subflava (ATCC 7468) or Micrococcus subflavus (ATCC 10240). The method is found in Antibiotic Residues in Milk, Dairy Products, and Animal Tissues: Methods, Reports and Protocols, Revised October 1968, Reprinted December 1974, Nation Center for Antibiotic and Insulin Analysis, FDA, Washington, DC 20204
Modified Method for the Determination of Bacitracin in Tissues, Test Procedure Code 9A, AL Laboratories, One Executive Dr. PO Box 1399, Fort Lee NJ 07024.
The analytical method for the determination of decoquinate in tissues uses a fluorometric assay procedure. This method is found in Official Methods of Analysis of AOAC International, 16th edition.
IV. AGENCY CONCLUSIONS
This ANADA submitted under section 512(b) of the Federal Food, Drug, and Cosmetic Act satisfies the requirements of section 512(n) of the act and demonstrates that the combination of decoquinate and bacitracin zinc, when used under its proposed conditions of use, is safe and effective for its labeled indications.
