21 CFR Parts 510 and 529


Certain Other Dosage Form New Animal Drugs; Competitive Exclusion 
Culture

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a new animal drug application 
(NADA) filed by BioScience Division of Milk Specialties Co. The NADA 
provides for use of a competitive exclusion culture (lyophilized 
bacterial cultures) for early establishment of intestinal microflora in 
chickens to reduce Salmonella colonization.

EFFECTIVE DATE: May 7, 1998.

FOR FURTHER INFORMATION CONTACT: Naba K. Das, Center for Veterinary 
Medicine (HFV-133), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-594-1659.

SUPPLEMENTARY INFORMATION: BioScience Division of Milk Specialties Co., 
Illinois and Water Sts., P.O. Box 278, Dundee, IL 60118, is sponsor of 
NADA 141-101 that provides for the use of Preempt<SUP>TM</SUP>, a 
competitive exclusion culture (lyophilized bacterial cultures), for the 
early establishment of intestinal microflora in chickens to reduce 
Salmonella colonization. The NADA is approved as of March 13, 1998, and 
the regulations are amended by adding 21 CFR 529.469 to reflect the 
approval. The basis of approval is discussed in the freedom of 
information summary.

    In addition, BioScience Division of Milk Specialties Co. has not 
been previously listed in the animal drug regulations as sponsor of an 
approved application. At this time, 21 CFR 510.600(c)(1) and (c)(2) are 
amended to add entries for the firm.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and 514.11(e)(2)(ii), a summary of safety and effectiveness 
data and information submitted to support approval of this application 
may be seen in the Dockets Management Branch (HFA-305), Food and Drug 
Administration, 12420 Parklawn Dr., rm. 1-23, Rockville, MD 20857, 
between 9 a.m. and 4 p.m., Monday through Friday.
    Under section 512(c)(2)(F)(i) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(i)), this approval for food-
producing animals qualifies for 5 years of marketing exclusivity 
beginning March 13, 1998, because no active ingredient (including any 
salt or ester of the active ingredient) has been approved in any other 
application.
    The agency has determined under 21 CFR 25.33(c) that this action is 
of a type that does not individually or cumulatively have a significant 
effect on the human environment. Therefore, neither an environmental 
assessment nor an environmental impact statement is required.
