Sec. 510.105  Labeling of drugs for use in milk-producing animals.


    (a) Part 526 of this chapter provides for new animal drugs intended 
for intramammary use in animals and includes conditions of use intended 
to prevent the contamination of milk from the use of such drugs.
    (b) Preparations containing antibiotics and other potent drugs 
labeled with directions for use in milk-producing animals will be 
misbranded under section 502(f)(2) of the act unless their labeling 
bears appropriate warnings and directions for use to avoid adulteration 
of milk under section 402(a)(2)(c)(ii) of the act.
    (c) It is the position of the Food and Drug Administration that the 
labeling for such preparations should bear a clear warning that either:
    (1) The article should not be administered to animals producing 
milk, since to do so would result in contamination of the milk; or
    (2) The label should bear the following statement: ``Warning: Milk 
that has been taken from animals during treatment and for ____ hours 
after the latest treatment must not be used for food'', the blank being 
filled in with the figure that the manufacturer has determined by 
appropriate investigation is needed to insure that the milk will not 
carry violative residues resulting from use of the preparation. If the 
use of the preparation as recommended does not result in contamination 
of the milk, neither of the above warning statements is required.

Sec. 510.106  Labeling of antibiotic and antibiotic-containing drugs intended for use in milk-producing animals.

    Whenever the labeling of an antibiotic drug included in the 
regulations in this chapter suggests or recommends its use in milk-
producing animals, the label of such drugs shall bear either the 
statement ``Warning: Not for use in animals producing milk, since this 
use

[[Page 40]]

will result in contamination of the milk'' or the statement ``Warning: 
Milk that has been taken from animals during treatment and for __ 
__hours after the latest treatment must not be used for food'', the 
blank being filled in with the figure that the Commissioner has 
authorized the manufacturer of the drug to use. The Commissioner shall 
determine what such figures shall be from information submitted by the 
manufacturer and which the Commissioner considers is adequate to prove 
that period of time after the latest treatment that the milk from 
treated animals will contain no violative residues from use of the 
preparation. If the Commissioner determines from the information 
submitted that the use of the antibiotic drug as recommended does not 
result in its appearance in the milk, the Commissioner may exempt the 
drug from bearing either of the above warning statements.

PART 510--NEW ANIMAL DRUGS--Table of Contents
 
        Subpart B--Specific Administrative Rulings and Decisions
 
Sec. 510.110  Antibiotics used in food-producing animals.

    (a) The Food and Drug Administration in the interest of fulfilling 
its responsibilities with regard to protection of the public health has 
requested an evaluation of the public health aspects of the use of 
antibiotics in veterinary medical and nonmedical uses. There is 
particular concern with regard to the potential hazards associated with 
the extensive use of antibiotics administered to food-producing animals. 
Accordingly, an ad hoc committee on the Veterinary Medical and 
Nonmedical Uses of Antibiotics was established by the Food and Drug 
Administration to study and advise the Commissioner of Food and Drugs on 
the uses of antibiotics in veterinary medicine and for various 
nonmedical purposes as such uses may affect the enforcement of the 
Federal Food, Drug, and Cosmetic Act with respect to their safety and 
effectiveness.
    (b) Based upon an evaluation of the conclusions of said Committee 
and other relevant material, Sec. 510.112 was published in the Federal 
Register of August 23, 1966 (31 FR 11141), asking sponsors of drugs 
containing any antibiotic intended for use in food-producing animals to 
submit data to establish whether such antibiotic and its metabolites are 
present as residues in edible tissues, milk, and eggs from treated 
animals. The data on the residues of antibiotics in milk from 
intramammary infusion preparations were requested within 60 days and the 
data on all other products were requested within 180 days following the 
date of publication of Sec. 510.112 in the Federal Register.
    (c) An evaluation of the data now available shows that use of many 
antibiotic preparations cause residues in edible products of treated 
animals for varying and, in some cases, for long periods of time 
following the last administration. Because of the accumulation of new 
information with regard to the development of resistance of bacteria to 
antibiotics, the ability of bacteria to transfer this resistance, and 
the development of sensitivity to antibiotics in humans, unauthorized 
and unsafe residues of antibiotics cannot be permitted in food obtained 
from treated animals.
    (d) Based on evaluation of information available, including the 
conclusions of the aforementioned ad hoc Committee, the Commissioner 
concludes that antibiotic preparations intended for use in food-
producing animals, other than topical and ophthalmic preparations, are 
not generally recognized among qualified experts as having been shown to 
be safe for their intended use(s) within the meaning of section 201(s) 
of the Federal Food, Drug, and Cosmetic Act.
    (e) Therefore, all exemptions from the provisions of section 409 of 
the act for use of antibiotics in food-producing animals based on 
sanctions or approvals granted prior to enactment of the Food Additives 
Amendment of 1958 (Pub. L. 85-929; 72 Stat. 1784) will be revoked and 
the uses which are concluded to be safe will be covered by food additive 
regulations. On those products for which there are inadequate residue 
data, actions will be initiated to withdraw approval of new-drug 
applications under the provisions of section 505 of the act. Antibiotic 
preparations, other than those for topical and ophthalmic application in 
food-producing animals, which are not covered by food additive 
regulations will be subject to regulatory action

[[Page 41]]

within 180 days after publication of the forthcoming revocation order.
    (f) Because of the variation in the period of time that antibiotic 
residues may remain in edible products from treated animals, all 
injectable, intramammary infusion, intrauterine, and oral preparations, 
including medicated premixes intended for use in food-producing animals, 
are deemed to be new drugs as well as food additives.

Sec. 510.112  Antibiotics used in veterinary medicine and for nonmedical purposes; required data.

    (a) An ad hoc committee, Committee on the Veterinary Medical and 
Nonmedical Uses of Antibiotics, was formed by the Food and Drug 
Administration to study, and advise the Commissioner on, the use of 
antibiotics in veterinary medicine and for various nonmedical purposes 
as such uses may affect the enforcement of the Federal Food, Drug, and 
Cosmetic Act with respect to the safety and effectiveness of such 
substances. A copy of the report may be obtained from the Food and Drug 
Administration, Office of Public Affairs, Room 15-05, Parklawn Building, 
5600 Fishers Lane, Rockville, MD 20857.
    (b) On the basis of the report of the Committee and other 
information, sponsors of drugs containing any antibiotic intended for 
use in food-producing animals shall submit data for determining whether 
or not such antibiotics and their metabolites are present as residues in 
edible tissues, milk, and eggs from treated animals; however, in the 
case of a drug for which such data have already been submitted and for 
which a regulation has been promulgated under section 409 of the act, 
only such data as has been accumulated since the issuance of the 
regulation need be submitted.
    (c) The required data shall be submitted within 180 days of the date 
of publication of this section in the Federal Register; except that in 
the case of data on intramammary infusion preparations the data shall be 
submitted within 60 days of such publication. Data demonstrating the 
absence in milk of residues of intramammary infusion preparations when 
used as directed in their labeling are needed within the 60-day period 
because of the importance of milk in the human diet.
    (d) Regulatory proceedings including revocation of prior sanctions, 
or actions to suspend or amend new drug or antibiotic approvals granted 
prior to passage of the Food Additives Amendment of 1958 (72 Stat. 
1784), may be initiated with regard to the continued marketing of any 
antibiotic preparation on which the required information is not 
submitted within the period of time prescribed by paragraph (c) of this 
section.
    (e) Questions relating to the acceptability of proposed research 
protocols and assay methods for determining the amount of antibiotic 
residues in food should be directed to the Director, Center for 
Veterinary Medicine, Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855.

[[Page 42]]

    (1) Unpublished reports of clinical or other animal experience, 
studies, investigations, and tests conducted by the applicant or 
reported to him by any person involving the new animal drug that is the 
subject of the application or any related drugs. An adequate summary and 
bibliography of reports in the scientific literature would ordinarily 
suffice. (The application must identify at the time of each report 
submission, each drug he considers related to the subject drug.)
    (2) Experience, investigations, studies, or tests involving the 
chemical or physical properties or any other properties of the new 
animal drug, such as its behavior or properties in relation to 
microorganisms, including both the effects of the drug on microorganisms 
and the effect of microorganisms on the drug.
    (3) For information required by this section, adequate 
identification of its source, when known, including the name and post 
office address of the person who furnishes such information.
    (4) Copies of all mailing pieces and other labeling, and, if it is a 
prescription new animal drug or a veterinary feed directive drug, all 
advertising other than that contained in the application used in 
promoting the drug, and copies of the currently used package labeling 
that gives full information for use of the drug whether or not such 
labeling is contained in the application.
    (5) Information concerning the quantity of the new animal drug 
distributed in a manner and form that facilitates estimates of the 
incidence of any adverse effects reported to be associated with the use 
of the drug. This does not require disclosure of financial, pricing, or 
sales data.
    (6) Information concerning any previously unreported changes from 
the conditions described in an application conforming to the conditions 
of Sec. 514.8(a)(5) of this chapter.
    (b) The applicant shall submit to the Food and Drug Administration 
copies of the records and reports described in paragraph (a) of this 
section, except routine assay and control records, appropriately 
identified with the new animal drug application(s) to which they relate, 
as follows:
    (1) Immediately upon receipt by the applicant, complete records or 
reports covering information of the following kinds:
    (i) Information concerning a mixup in the new animal drug or its 
labeling with another article.
    (ii) Information concerning any bacteriological or significant 
physical or other change or deterioration in the new animal drug, or any 
failure of one or more distributed batches of the drug to meet the 
specifications established for it in the new animal drug application.
    (2) As soon as possible, and in any event within 15 working days of 
its receipt by the applicant, complete records of reports concerning any 
information of the following kinds:
    (i) Information concerning any unexpected side effects, injury, 
toxicity, or sensitivity reaction or any unexpected incidence or 
severity thereof associated with clinical use, studies, investigations, 
or tests, whether or not determined to be attributable to the new animal 
drug, except that this requirement shall not apply to the submission of 
information described in a written communication to the applicant from 
the Food and Drug Administration as types of information that may be 
submitted at other designated intervals. Unexpected as used in this 
subdivision refers to conditions or developments not previously 
submitted as part of the new animal drug application, or conditions and 
developments occurring at a rate higher than that shown by information 
previously submitted as part of the application.
    (ii) Information concerning any unusual failure of the new animal 
drug to exhibit its expected pharmacological activities.
    (3) When mailing pieces, any other labeling, and advertising are 
devised for promotion of the new animal drug, specimens shall be 
submitted at the time of initial dissemination of such labeling and at 
the time of initial publication of any advertisement for a prescription 
drug. Mailing pieces and labeling designed to contain samples of a drug 
shall be complete except for the omission of the drug.
    (4) All the kinds of information described in paragraph (a) of this

repeatedly or deliberately failed to maintain such records or to make 
required reports in accordance with the provisions of this section, or 
that the applicant has refused to permit access to or copying of, or 
verification of such records or reports, the Commissioner shall give the 
applicant notice and opportunity for a hearing on the question of 
whether to withdraw the approval of the application, as provided in 
Sec. 514.200 of this chapter.
    (e) Upon written request of the applicant stating reasonable grounds 
therefor, the Commissioner will make available any information in 
possession of the Food and Drug Administration of the kinds the 
applicant is required to maintain under the provisions of this section, 
except information readily available to the applicant from other sources 
or information which the Commissioner concludes is confidential.
    (f) The applicant required to establish and maintain records and 
make reports required by this section includes any person whose name 
appears on the labeling of the drug as its manufacturer, packer, or 
distributor under an approval or who is engaged in the manufacturing, 
processing, packing, or labeling of the drug under an approval of the 
new animal drug application or any supplement to it; however, to avoid 
unnecessary duplication in the submission of reports, any such 
applicant's obligation to submit a report may be met by its submission

Sec. 510.410  Corticosteroids for oral, injectable, and ophthalmic use in animals; warnings and labeling requirements.


    (a) The Food and Drug Administration has received reports of side 
effects associated with the oral, injectable, and ophthalmic use of 
corticosteroid animal drugs. The use of these drugs administered orally 
or by injection has resulted in premature parturition when administered 
during the last trimester of pregnancy. Premature parturition may be 
followed by dystocia, fetal death, retained placenta, and metritis. 
Additionally, corticosteroids used in dogs, rabbits, and rodents during 
pregnancy have produced cleft palate in offspring. Use in dogs has 
resulted in other congenital anomalies, including deformed forelegs, 
phocomelia, and anasarca. Drugs subject to this section are required to 
carry the veterinary prescription legend and are subject to the labeling 
requirements of Sec. 201.105 of this chapter.
    (b) In view of these potentially serious side effects, the Food and 
Drug Administration has concluded that the labeling on or within 
packaged corticosteroid-containing preparations intended for animal use 
shall bear conspicuously the following warning statement:

    Warning: Clinical and experimental data have demonstrated that 
corticosteroids administered orally or by injection to animals may 
induce the first stage of parturition if used during the last trimester 
of pregnancy and may precipitate premature parturition followed by 
dystocia, fetal death, retained placenta, and metritis.
    Additionally, corticosteroids administered to dogs, rabbits, and 
rodents during pregnancy have resulted in cleft palate in offspring. 
Corticosteroids administered to dogs during pregnancy have also resulted 
in other congenital anomalies, including deformed forelegs, phocomelia, 
and anasarca.

Sec. 510.440  Injectable iron preparations.

    There has been an increasing interest in the use of injectable iron 
compounds for the prevention or treatment of iron-deficiency anemia in 
animals. Although some such preparations have been shown to be safe, 
such articles are regarded as new animal drugs within the meaning of the 
Federal Food, Drug, and Cosmetic Act. Accordingly, an approved new 
animal drug application is required prior to the marketing of such 
preparations within the jurisdiction of the act. In addition to the need 
for demonstrating the safety of such articles, the labeling of such 
preparations should not only recommend appropriate dosages of iron but 
also declare the amount (in milligrams) of available iron (Fe) per 
milliliter of the subject product.

PART 510--NEW ANIMAL DRUGS--Table of Contents
 
          Subpart E--Requirements for Specific New Animal Drugs
 
Sec. 510.455  New animal drug requirements regarding free-choice administration in feeds.

    (a) For the purpose of this section, free-choice administration of 
animal drugs in feeds involves feeds that are placed in feeding or 
grazing areas and are not intended to be consumed fully at a single 
feeding or to constitute the entire diet of the animal. Such methods of 
administering drugs include, but are not limited to, medicated blocks 
(agglomerated feed compressed or rendered into a solid mass and cohesive 
enough to hold its form), mineral mixes, and liquid feed tank 
supplements (``lick tank'' supplements) containing one or more animal 
drugs. The manufacture of medicated free-choice feeds is subject to the 
current good manufacturing practice regulations for medicated feeds.
    (b) The Food and Drug Administration has concluded that there are 
questions about the safety and effectiveness of drugs when administered 
in free-choice feeds. Therefore, such methods of administration cause 
the drugs so administered to be new animal drugs, for which approved new 
animal drug applications (NADA's) are required. (See Sec. 510.3(i)). In 
addition, the exemption from the requirement of an approved medicated 
feed application provided in Sec. 558.4 of this chapter does not apply 
to any free-choice medicated feed.
    (c) An NADA or supplemental NADA for products for free-choice 
feeding submitted for approval under section 512(b) of the act shall 
provide for:

[[Page 46]]

    (1) The manufacture of a finished product for the free-choice 
administration of a new animal drug. Such an approval will not provide a 
basis upon which an application can be approved under section 512(m) of 
the act; or
    (2) The manufacture of a Type A medicated article for use in the 
subsequent manufacture of a free-choice medicated feed. The approved 
NADA will provide a basis upon which an application can be approved 
under section 512(m) of the act. Data for a specific free-choice product 
may, if desired, be generated and submitted to the Food and Drug 
Administration by the manufacturer of the free-choice feed in the form 
of a master file which can be referenced in the NADA or supplemental 
NADA submitted by the new animal drug sponsor.
    (d) Approval of the NADA or supplemental NADA submitted under 
paragraph (c) of this section will be reflected in a regulation in part 
558 of this chapter published under section 512(i) of the act. The 
regulation will either state the formulation of the approved free-choice 
product or specify the specific free-choice administration products in 
which the drug is approved for use. If the approval is for a Type A 
medicated article, the regulation in part 558 of this chapter will 
indicate that each use of the Type A medicated article in a free-choice 
product must be the subject of an approved supplemental NADA.
    (e) An application submitted under section 512(m) of the act to 
provide for manufacture of a specific free-choice feed from an approved 
Type A medicated article will be approved if, in addition to the 
information required by the medicated feed application, it includes a 
reference to the exact formula of the product to be manufactured as 
follows:
    (1) The formula is the same as the one published in the new animal 
drug regulations; or
    (2) The data in a master file have been referenced in an NADA or 
supplemental NADA; and
    (3) Use of the Type A medicated article in the specific formulation 
has been approved on the basis that:
    (i) The formula is the same as the one for which acceptable data 
have been submitted in a master file by the medicated feed applicant; or
    (ii) The medicated feed applicant has written authority to reference 
a master file that has acceptable data for the formula in question.
