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 Pennfield Oil Co. that provides for a zero-day preslaughter withdrawal time following use of oxytetracycline in turkey and swine feed.
Pennfield Oil Co., 14040 Industrial Rd., Omaha, NE 68144, filed a supplement to NADA 138-938 for PENNOX (oxytetracycline) Type A medicated articles used for making medicated feeds for the treatment of various bacterial diseases of livestock and fish. The supplemental NADA provides for a zero-day withdrawal time prior to slaughter when Type C medicated feeds containing oxytetracycline are fed to turkeys or swine and for minor label revisions. The supplemental application is approved as of November 26, 2007, and the regulations are amended in 21 CFR 558.450 to reflect the approval, an editorial change, and a current format.
