As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these changes of sponsorship. Elanco US, Inc., is retaining Novartis' drug labeler code (058198). Accordingly, the animal drug regulations need only be amended in § 510.600(c) to add Elanco US, Inc., who previously was not the sponsor of an approved application. Cronus Pharma LLC will also be added as a new listing. Following these changes of sponsorship, Novartis is no longer the sponsor of an approved application and will be removed from § 510.600(c).
**III. Technical Amendments**
FDA has noticed the animal drug regulations in 21 CFR part 556 contain tolerances for residues in edible tissues for sulfathiazole, which is no longer the subject of an approved application (79 FR 15540, March 20, 2014). Accordingly, § 556.690 is being removed. FDA has also noticed that the animal drug regulations in 21 CFR 558.4 (§ 558.4) contain assay limits for ronnel and sulfaethoxypyridazine in medicated feed. As there is no longer an approved application for use of either of these drugs in medicated feed, the table for Category II drugs in § 558.4 is being amended to remove assay limits in medicated feed for both drugs. These actions are being taken to improve the accuracy of the regulations.
In addition, FDA is taking this opportunity to revise the spelling of a bacitracin salt to a preferred form, bacitracin methylenedisalicylate, and to correct the spelling of a genus of pathogenic bacteria, *Haemophilus.* These actions are being taken to improve the accuracy of the regulations.
This rule does not meet the definition of “rule” in 5 U.S.C. 804(3)(A) because it is a rule of “particular applicability.” Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.
**List of Subjects**
Administrative practice and procedure, Animal drugs, Labeling, Reporting and recordkeeping requirements.
Animal drugs.
Animal drugs, Foods.
Animal drugs, Animal feeds.
