SUMMARY: 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 Roche Vitamins, Inc. The supplemental NADA 
provides for a zero-day withdrawal period for use of 500 grams per ton 
(g/t) chlortetracycline (CTC) Type C medicated chicken feeds.

EFFECTIVE DATE: November 27, 1998.

FOR FURTHER INFORMATION CONTACT: Dianne T. McRae, Center for Veterinary 
Medicine (HFV-102), Food and Drug Administration, 7500 Standish Pl.,

for use of Aureomycin<Register> (CTC) Type A medicated articles to make

are used for 5 days for reduction of mortality due to CTC susceptible 
Escherichia coli infections. The supplement provides for reducing the 
24-hour withdrawal period to a zero-day slaughter withdrawal period.

information summary.
    In accordance with the freedom of information provisions of 21 CFR

data and information submitted to support approval of this supplemental 
application may be seen in the Dockets Management Branch (HFA-305), 
Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, 
MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
    The agency has determined under 21 CFR 25.33(a)(3) that this action 
is of a type that does not individually or cumulatively have a
