II. EFFECTIVENESS AND TARGET ANIMAL SAFETY

In accordance with the Center for Veterinary Medicine's policy letter dated November 2, 1989, as published in the Federal Register on January 30, 1990 (55 FR 3107), following the approval of an ANADA for a generic Type A Medicated article (ANADA 200-223, generic bacitracin zinc), ALPHARMA, Inc., is entitled to the approval of generic bacitracin zinc in combination with salinomycin. Bioequivalence studies are not required for the approval of this generic combination (Type C Medicated feed). Bacitracin zinc is codified under 21 CFR §558.78. Salinomycin is codified under 21 CFR §558.550. The combination of bacitracin zinc and salinomycin is codified under 21 CFR §558.550 (b) (1) (vii).

 

III. HUMAN SAFETY

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).

Under NADA 128-686 a tolerance for salinomycin was not required because residue levels in all three broiler tissues (muscle, liver, and skin/fat) were significantly below the established safe concentration for total residues.

Withdrawal Time
Based on the information in 21 CFR §558.550(b)(1)(vii), a withdrawal time is not required for the use of the combination of bacitracin and salinomycin 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, National 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.

Under NADA 128-686 a regulatory method for salinomycin was not required because residue levels in all three broiler tissues (muscle, liver, and skin/fat) were significantly below the established safe concentration for total residues.

 

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 salinomycin and bacitracin zinc, when used under its proposed conditions of use, is safe and effective for its labeled indications.
