Start Preamble


Food and Drug Administration, HHS.


Final rule; correcting amendments.


The Food and Drug Administration (FDA) is correcting a document amending the animal drug regulations to reflect approval of an original abbreviated new animal drug application (ANADA) that appeared in the Federal Register of August 18, 2004 (69 FR 51172). FDA is removing the drug labeler code for Pennfield Oil Co. in the entry for use of single-ingredient bacitracin methylene disalicylate (BMD) in swine feed, which was added in error during document formatting; and is adding the approved source of BMD in the entry for use of BMD in combination with chlortetracycline. These corrections are being made so the BMD regulations accurately reflect approved new animal drug applications.


This rule is effective September 27, 2004.
