                   Subpart B--Establishment Standards
 
Sec. 600.11  Physical establishment, equipment, animals, and care.

    (a) Work areas. All rooms and work areas where products are 
manufactured or stored shall be kept orderly, clean, and free of dirt, 
dust, vermin and objects not required for manufacturing. Precautions 
shall be taken to avoid clogging and back-siphonage of drainage systems. 
Precautions shall be taken to exclude extraneous infectious agents from 
manufacturing areas. Work rooms shall be well lighted and ventilated. 
The ventilation system shall be arranged so as to prevent the 
dissemination of microorganisms from one manufacturing area to another 
and to avoid other conditions unfavorable to the safety of the product. 
Filling rooms, and other rooms where open, sterile operations are 
conducted, shall be adequate to meet manufacturing needs and such rooms 
shall be constructed and equipped to permit thorough cleaning and to 
keep air-borne contaminants at a minimum. If such rooms are used for 
other purposes, they shall be cleaned and prepared prior to use for 
sterile operations. Refrigerators, incubators and warm rooms shall be 
maintained at temperatures within applicable ranges and shall be free of 
extraneous material which might affect the safety of the product.
    (b) Equipment. Apparatus for sterilizing equipment and the method of 
operation shall be such as to insure the destruction of contaminating 
microorganisms. The effectiveness of the sterilization procedure shall 
be no less than that achieved by an attained temperature of 121.5 deg. C 
maintained for 20 minutes by saturated steam or by an attained 
temperature of 170 deg. C maintained for 2 hours with dry heat. 
Processing and storage containers, filters, filling apparatus, and other 
pieces of apparatus and accessory equipment, including pipes and tubing, 
shall be designed and constructed to permit thorough cleaning and, where 
possible, inspection for cleanliness. All surfaces that come in contact 
with products shall be clean and free of surface solids, leachable 
contaminants, and other materials that will hasten the deterioration of 
the product or otherwise render it less suitable for the intended use. 
For products for which sterility is a factor, equipment shall be 
sterile, unless sterility of the product is assured by subsequent 
procedures.
    (c) Laboratory and bleeding rooms. Rooms used for the processing of 
products, including bleeding rooms, shall be effectively fly-proofed and 
kept free of flies and vermin. Such rooms shall be so constructed as to 
insure freedom from dust, smoke and other deleterious substances and to 
permit thorough cleaning and disinfection. Rooms for animal injection 
and bleeding, and rooms for smallpox vaccine animals, shall be 
disinfected and be provided with the necessary water, electrical and 
other services.
    (d) Animal quarters and stables. Animal quarters, stables and food 
storage areas shall be of appropriate construction, fly-proofed, 
adequately lighted and ventilated, and maintained in a clean, vermin-
free and sanitary condition. No manure or refuse shall be stored as to 
permit the breeding of flies on the premises, nor shall the 
establishment be located in close proximity to off-property manure or 
refuse storage capable of engendering fly breeding.
    (e) Restrictions on building and equipment use--(1) Work of a 
diagnostic nature. Laboratory procedures of a clinical diagnostic nature 
involving materials that may be contaminated, shall not be performed in 
space used for the manufacture of products except that manufacturing 
space which is used

[[Page 9]]

only occasionally may be used for diagnostic work provided spore-bearing 
pathogenic microorganisms are not involved and provided the space is 
thoroughly cleaned and disinfected before the manufacture of products is 
resumed.
    (2) Spore-bearing organisms for supplemental sterilization procedure 
control test. Spore-bearing organisms used as an additional control in 
sterilization procedures may be introduced into areas used for the 
manufacture of products, only for the purposes of the test and only 
immediately before use for such purposes: Provided, That (i) the 
organism is not pathogenic for man or animals and does not produce 
pyrogens or toxins, (ii) the culture is demonstrated to be pure, (iii) 
transfer of test cultures to culture media shall be limited to the 
sterility test area or areas designated for work with spore-bearing 
organisms, (iv) each culture be labeled with the name of the 
microorganism and the statement ``Caution: microbial spores. See 
directions for storage, use and disposition.'', and (v) the container of 
each culture is designed to withstand handling without breaking.
    (3) Work with spore-bearing organisms. Except as provided in the 
previous paragraph, all work with spore-bearing microorganisms shall be 
done in an entirely separate building: Provided, That such work may be 
done in a portion of a building used in the manufacture of products not 
containing spore-bearing microorganisms if such portion is completely 
walled-off and is constructed so as to prevent contamination of other 
areas and if entrances to such portion are independent of the remainder 
of the building. All vessels, apparatus and equipment used for spore-
bearing microorganisms shall be permanently identified and reserved 
exclusively for use with those organisms. Materials destined for further 
manufacturing may be removed from such an area only under conditions 
which will prevent the introduction of spores into other manufacturing 
areas.
    (4) Live vaccine processing. Space used for processing a live 
vaccine shall not be used for any other purpose during the processing 
period for that vaccine and such space shall be decontaminated prior to 
initiation of the processing. Live vaccine processing areas shall be 
isolated from and independent of any space used for any other purpose by 
being either in a separate building, in a separate wing of a building, 
or in quarters at the blind end of a corridor and shall include adequate 
space and equipment for all processing steps up to filling into final 
containers. Test procedures which potentially involve the presence of 
microorganisms other than the vaccine strains, or the use of tissue 
culture cell lines other than primary cultures, shall not be conducted 
in space used for processing live vaccine.
    (5) Equipment and supplies--contamination. Equipment and supplies 
used in work on or otherwise exposed to any pathogenic or potentially 
pathogenic agent shall be kept separated from equipment and supplies 
used in the manufacture of products to the extent necessary to prevent 
cross-contamination.
    (f) Animals used in manufacture--(1) Care of animals used in 
manufacturing. Caretakers and attendants for animals used for the 
manufacture of products shall be sufficient in number and have adequate 
experience to insure adequate care. Animal quarters and cages shall be 
kept in sanitary condition. Animals on production shall be inspected 
daily to observe response to production procedures. Animals that become 
ill for reasons not related to production shall be isolated from other 
animals and shall not be used for production until recovery is complete. 
Competent veterinary care shall be provided as needed.
    (2) Quarantine of animals--(i) General. No animal shall be used in 
processing unless kept under competent daily inspection and preliminary 
quarantine for a period of at least 7 days before use, or as otherwise 
provided in this subchapter. Only healthy animals free from detectable 
communicable diseases shall be used. Animals must remain in overt good 
health throughout the quarantine periods and particular care shall be 
taken during the quarantine periods to reject animals of the equine 
genus which may be infected with glanders and animals which may be 
infected with tuberculosis.

[[Page 10]]

    (ii) Quarantine of monkeys. In addition to observing the pertinent 
general quarantine requirements, monkeys used as a source of tissue in 
the manufacture of vaccine shall be maintained in quarantine for at 
least 6 weeks prior to use, except when otherwise provided in this part. 
Only monkeys that have reacted negatively to tuberculin at the start of 
the quarantine period and again within 2 weeks prior to use shall be 
used in the manufacture of vaccine. Due precaution shall be taken to 
prevent cross-infection from any infected or potentially infected 
monkeys on the premises. Monkeys to be used in the manufacture of a live 
vaccine shall be maintained throughout the quarantine period in cages 
closed on all sides with solid materials except the front which shall be 
screened, with no more than two monkeys housed in one cage. Cage mates 
shall not be interchanged.
    (3) Immunization against tetanus. Horses and other animals 
susceptible to tetanus, that are used in the processing steps of the 
manufacture of biological products, shall be treated adequately to 
maintain immunity to tetanus.
    (4) Immunization and bleeding of animals used as a source of 
products. Toxins or other nonviable antigens administered in the 
immunization of animals used in the manufacture of products shall be 
sterile. Viable antigens, when so used, shall be free of contaminants, 
as determined by appropriate tests prior to use. Injections shall not be 
made into horses within 6 inches of bleeding site. Horses shall not be 
bled for manufacturing purposes while showing persistent general 
reaction or local reaction near the site of bleeding. Blood shall not be 
used if it was drawn within 5 days of injecting the animals with viable 
microorganisms. Animals shall not be bled for manufacturing purposes 
when they have an intercurrent disease. Blood intended for use as a 
source of a biological product shall be collected in clean, sterile 
vessels. When the product is intended for use by injection, such vessels 
shall also be pyrogen-free.
    (5) [Reserved]
    (6) 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 in the 
manufacture of products, the manufacturer shall immediately notify the 
Director, Center for Biologics Evaluation and Research.
    (7) Monkeys used previously for experimental or test purposes. 
Monkeys that have been used previously for experimental or test purposes 
with live microbiological agents shall not be used as a source of kidney 
tissue for the manufacture of vaccine. Except as provided otherwise in 
this subchapter, monkeys that have been used previously for other 
experimental or test purposes may be used as a source of kidney tissue 
upon their return to a normal condition, provided all quarantine 
requirements have been met.
    (8) Necropsy examination of monkeys. Each monkey used in the 
manufacture of vaccine shall be examined at necropsy under the direction 
of a qualified pathologist, physician, or veterinarian having experience 
with diseases of monkeys, for evidence of ill health, particularly for 
(i) evidence of tuberculosis, (ii) presence of herpes-like lesions, 
including eruptions or plaques on or around the lips, in the buccal 
cavity or on the gums, and (iii) signs of conjunctivitis. If there are 
any such signs or other significant gross pathological lesions, the 
tissue shall not be used in the manufacture of vaccine.
    (g) Filling procedures. Filling procedures shall be such as will not 
affect adversely the safety, purity or potency of the product.
    (h) Containers and closures. All final containers and closures shall 
be made of material that will not hasten the deterioration of the 
product or otherwise render it less suitable for the intended use. All 
final containers and closures shall be clean and free of surface solids, 
leachable contaminants and other materials that will hasten the 
deterioration of the product or otherwise render it less suitable for 
the intended use. After filling, sealing shall be performed in a manner 
that will maintain the integrity of the product during the dating 
period. In addition, final containers and closures for products intended 
for use by injection shall be sterile and

[[Page 11]]

free from pyrogens. Except as otherwise provided in the regulations of 
this subchapter, final containers for products intended for use by 
injection shall be colorless and sufficiently transparent to permit 
visual examination of the contents under normal light. As soon as 
possible after filling final containers shall be labeled as prescribed 
in Sec. 610.60 et seq. of this chapter, except that final containers may 
be stored without such prescribed labeling provided they are stored in a 
sealed receptacle labeled both inside and outside with at least the name 
of the product, the lot number, and the filling identification.
