-----------------------------------------------------------------------

SUMMARY:  The Food and Drug Administration (FDA) is amending the animal

taken to improve the accuracy of the animal drug regulations.

FOR FURTHER INFORMATION CONTACT:  George K. Haibel, Center for 
Veterinary Medicine (HFV-6), Food and Drug Administration, 7519

SUPPLEMENTARY INFORMATION: FDA is amending the animal drug regulations 
in 21 CFR 558.95 to correct an inadvertent error in the conditions of 
use of fenbendazole paste in horses and cattle. The error in the 
agency's regulations was introduced in a final rule reflecting the 
approval of a supplemental new animal drug application that published 
in the Federal Register on March 9, 2007 (72 FR 10595). This action is 
being taken to improve the accuracy of the animal drug regulations.
    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.
