**SUPPLEMENTARY INFORMATION :**  Teva Animal Health, Inc., 3915 South 48th Street Ter., St. Joseph, MO 64503, has informed FDA that it has transferred ownership of, and all rights and interest in, ANADA 200–136 for Tetracycline Hydrochloride Soluble Powder 324; ANADA 200–303 for Lincomycin Hydrochloride Soluble Powder; and ANADA 200–347 for Penicillin G Potassium, USP, all soluble powders administered in drinking water to Quo Vademus, LLC, 277 Faison West McGowan Rd., Kenansville, NC 28349. Accordingly, the Agency is amending the regulations in part 520 (21 CFR part 520) to reflect the transfer of ownership and a current format.

In addition FDA has noticed two errors in § 520.1696 Penicillin oral dosage forms. At this time, § 520.1696a is being removed because no sponsor is listed, and an obsolete drug labeler code is being removed from § 520.1696d.
