## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Pharmacia & Upjohn Co. The supplemental NADA provides for use of ceftiofur crystalline free acid suspension via a new injection site in beef and nonlactating dairy cattle, for use in lactating dairy cattle for the treatment of respiratory disease, and for the establishment of a 13-day pre-slaughter withdrawal period in cattle. FDA is also amending the regulations to revise the tolerance for residues of ceftiofur in bovine kidney to accommodate these new conditions of use.
