**SUPPLEMENTARY INFORMATION:**
PM Resources, Inc., 13001 St. Charles Rock Rd., Bridgeton, MO 63044, has informed FDA that it has transferred ownership of, and all rights and interest in, the following four approved NADAs to Virbac AH, Inc., 3200 Meacham Blvd., Ft. Worth, TX 76137:
| Application No. | 21 CFR Section | Trade Name |
| --- | --- | --- |
| NADA 007-076 | 520.2325a | SULFA-NOX (sulfaquinoxaline) Liquid |
| NADA 008-244 | 520.2325a | SULFA-NOX (sulfaquinoxaline) Concentrate |
| NADA 043-215 | 524.900 | PURINA Grub-Kill (famphur) |
| NADA 092-150 | 520.2045 | PURINA Horse & Colt Wormer (pyrantel tartrate) |
Accordingly, the agency is amending the regulations in 21 CFR 520.2045, 520.2325a, and 524.900 to reflect the transfer of ownership.
Following these changes of sponsorship, PM Resources, Inc., is no longer the sponsor of an approved application. Accordingly, § 510.600(c) is being amended to remove the entries for PM Resources, Inc.
