PART 680--ADDITIONAL STANDARDS FOR MISCELLANEOUS PRODUCTS--Table of Contents
 
Sec. 680.1  Allergenic Products.

    (a) Definition. Allergenic Products are products that are 
administered to man for the diagnosis, prevention or treatment of 
allergies.
    (b) Source materials--(1) Criteria for source material. Only 
specifically identified allergenic source materials that contain no more 
than a total of 1.0 percent of detectable foreign materials shall be 
used in the manufacture of Allergenic Products, except that this 
requirement shall not apply to molds and animals described under 
paragraphs (b) (2) and (3) of this section, respectively. Source 
materials such as pelts, feathers, hairs, and danders shall be collected 
in a manner that will minimize contamination of the source material.
    (2) Molds. (i) Molds (excluding rusts and smuts) used as source 
material in the manufacture of Allergenic Products shall meet the 
requirements of Sec. 610.18 of this chapter and Sec. 680.2 (a) and (b).

    (ii) Mold cultures shall be free of contaminating materials 
(including microorganisms) prior to harvest, and care shall be taken to 
minimize contamination during harvest and subsequent processing.
    (iii) Mold manufacturers shall maintain written standard operating 
procedures, developed by a qualified individual, that will ensure the 
identity of the seed culture, prescribe adequate processing of the mold, 
and specify the acceptable limits and kinds of contamination. These 
limits shall be based on results of appropriate tests performed by the 
manufacturer on at least three consecutive lots of a mold that is a 
representative species of mold subject to the standard operating 
procedures. The tests shall be performed at each manufacturing step 
during and subsequent to harvest, as specified in the standard operating 
procedures. Before use of the mold as a source material for Allergenic 
Products, in accordance with 21 CFR 601.2, the standard operating 
procedures and test data from the three representative lots described 
above shall be submitted to and approved by the Director, Center for 
Biologics Evaluation and Research (HFB-1).
    (3) Mammals and birds--(i) Care of animals. Animals intended as a 
source material for Allergenic Products shall be maintained by competent 
personnel in facilities or designated areas that will ensure adequate 
care. Competent veterinary care shall be provided as needed.
    (ii) Health of animals. Only animals in good health and free from 
detectable skin diseases shall be used as a source material for 
Allergenic Products. The determination of good health prior to 
collection of the source material shall be made by a licensed 
veterinarian or a competent individual under the supervision and 
instruction of a licensed veterinarian provided that the licensed 
veterinarian certifies in writing that the individual is capable of 
determining the good health of the animals.
    (iii) Immunization against tetanus. Animals of the equine genus 
intended as a source material for Allergenic Products shall be treated 
to maintain immunity to tetanus.
    (iv) Reporting of certain diseases. In cases of actual or suspected 
infection with foot and mouth disease, glanders, tetanus, anthrax, gas 
gangrene, equine infectious anemia, equine encephalomyelitis, or any of 
the pock diseases among animals intended for use or used as source 
material in the manufacture of allergenic Products, the manufacturer 
shall immediately notify the Director, Center for Biologics Evaluation 
and Research (HFB-1).
    (v) Dead animals. Dead animals may be used as source material in the 
manufacture of Allergenic Products: Provided, That (a) the carcasses 
shall be frozen or kept cold until the allergen can be collected, or 
shall be stored under other acceptable conditions so that the postmortal 
decomposition processes do not adversely affect the allergen, and (b) 
when alive, the animal met the applicable requirements prescribed in 
paragraphs (b)(3) (i), (ii), and (iii) of this section.
    (vi) Mammals and birds inspected by the U.S. Department of 
Agriculture. Mammals and birds, subject to inspection by the U.S. 
Department of Agriculture at the time of slaughter and found suitable as 
food, may be used as a source material, and the requirements of 
paragraph (b)(3) (i) through (iv) of this section do not apply in such a 
case. Notwithstanding U.S. Department of Agriculture inspection, the 
carcasses of such inspected animals shall be frozen or kept cold until 
the allergen is collected, or shall be stored under other acceptable 
conditions so that the postmortal decomposition processes do not 
adversely affect the allergen.
    (c) Listing of source materials and suppliers. Each licensed 
manufacturer shall initially list with the Director, Center for 
Biologics Evaluation and Research (HFB-1), the name and address of each 
of the manufacturer's source material suppliers. The listing shall 
identify each source material obtained from each source material 
supplier. The licensed manufacturers shall update the listing annually 
to include new source material suppliers or to delete those no longer 
supplying source materials.

    (d) Exemptions. (1) Exemptions or modifications from the 
requirements under paragraph (b) of this section shall be made only upon 
written approval by the Director, Center for Biologics Evaluation and 
Research (HFB-1).
    (2) Nonlicensed source material suppliers are exempt from drug 
registration.
