21 CFR Part 528


New Animal Drugs For Use In Animal Feeds; Monensin; Technical 
Amendment

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; technical amendment.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations for monensin by removing the duplicate assay limits 
that appear in the regulations. This action is necessary to ensure the 
accuracy and consistency of the regulations.

EFFECTIVE DATE:  March 24, 1998.

FOR FURTHER INFORMATION CONTACT: David L. Gordon, Center for Veterinary 
Medicine (HFV-6), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-594-1739.

SUPPLEMENTARY INFORMATION: In the animal drug regulations, provisions 
for the assay limits for monensin liquid feeds were established in the 
regulations for medicated feed applications in Sec. 558.4(d) (21 CFR 
558.4(d)) in the Category I table and in the monensin regulation in 
Sec. 558.355(c) (21 CFR 558.355(c)). In issuing the medicated feed 
regulations, assay limits were relegated to Sec. 558.4(d) in the 
Federal Register of March 3, 1986 (51 FR 7382 at 7393). Inadvertently, 
the monensin liquid feed assay limits were also established in 
Sec. 558.355(c). At this time, those limits in Sec. 558.355(c) are 
removed and the paragraph reserved.
