ACTION:
Final rule.
SUMMARY: The Food and Drug
Administration (FDA) is amending the
animal drug regulations to reflect
approval of four supplemental new
animal drug applications (NADAs) filed
by Pharmacia & Upjohn Co. The
supplemental NADAs establish or revise
preslaughter withdrawal periods in
cattle injected with a solution made
from ceftiofur sodium powder or with a
suspension of ceftiofur hydrochloride,
or receiving an intramammary infusion
of ceftiofur hydrochloride.
DATES: This rule is effective July 13,
2006.

SUPPLEMENTARY INFORMATION: Pharmacia

Powder for Injection and to NADA 140–
890 for EXCENEL RTU (ceftiofur
hydrochloride) Sterile Suspension.
These products are approved for
veterinary prescription use in livestock
by injection for the treatment or control
of various bacterial diseases. Pharmacia
& Upjohn Co. also filed supplements to
NADA 141–238 for SPECTRAMAST LC
(ceftiofur hydrochloride) Sterile
Suspension and to NADA 141–239 for
SPECTRAMAST DC (ceftiofur
hydrochloride) Sterile Suspension.
These products are approved for
veterinary prescription use by
intramammary infusion in dairy cows
for the treatment of bacterial mastitis.
The supplemental NADAs establish or
revise preslaughter withdrawal periods
in cattle consistent with the tolerance
for residues of ceftiofur in bovine
kidney which was revised elsewhere in
this issue of the Federal Register. The
applications are approved as of June 2,
2006, and the regulations are amended
in 21 CFR 522.313 and 526.314 to reflect
the approval. The basis of approval is
discussed in the freedom of information
summaries.
In accordance with the freedom of
information provisions of 21 CFR part
20 and 21 CFR 514.11(e)(2)(ii),
summaries of the safety and
effectiveness data and information
submitted to support approval of these
applications may be seen in the Division
of Dockets Management (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) that these actions are of a
type that do not individually or
cumulatively have a significant effect on
the human environment. Therefore,
neither an environmental assessment
nor an environmental impact statement
is required.
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.
