To cite the regulations in this volume use title, part and section number. Thus, 21 CFR 500.23 refers to title 21, part 500, section 23. Explanation

The Code of Federal Regulations is a codification of the general and permanent rules published in the Federal Register by the Executive departments and agencies of the Federal Government. The Code is divided into 50 titles which represent broad areas subject to Federal regulation. Each title is divided into chapters which usually bear the name of the issuing agency. Each chapter is further subdivided into parts covering specific regulatory areas.

Each volume of the Code is revised at least once each calendar year and issued on a quarterly basis approximately as follows:

Title 1 through Title 16

as of January 1

Title 17 through Title 27

as of April 1

Title 28 through Title 41

as of July 1

Title 42 through Title 50

as of October 1

The appropriate revision date is printed on the cover of each volume.

LEGAL STATUS

The contents of the Federal Register are required to be judicially noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie evidence of the text of the original documents (44 U.S.C. 1510).

 HOW TO USE THE CODE OF FEDERAL REGULATIONS

The Code of Federal Regulations is kept up to date by the individual issues of the Federal Register. These two publications must be used together to determine the latest version of any given rule.

To determine whether a Code volume has been amended since its revision date (in this case, April 1, 2000), consult the “List of CFR Sections Affected (LSA),” which is issued monthly, and the “Cumulative List of Parts Affected,” which appears in the Reader Aids section of the daily Federal Register. These two lists will identify the Federal Register page number of the latest amendment of any given rule.

 EFFECTIVE AND EXPIRATION DATES

Each volume of the Code contains amendments published in the Federal Register since the last revision of that volume of the Code. Source citations for the regulations are referred to by volume number and page number of the Federal Register and date of publication. Publication dates and effective dates are usually not the same and care must be exercised by the user in determining the actual effective date. In instances where the effective date is beyond the cut-off date for the Code a note has been inserted to reflect the future effective date. In those instances where a regulation published in the Federal Register states a date certain for expiration, an appropriate note will be inserted following the text.

 OMB CONTROL NUMBERS

The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires Federal agencies to display an OMB control number with their information collection request. Many agencies have begun publishing numerous OMB control numbers as amendments to existing regulations in the CFR. These OMB numbers are placed as close as possible to the applicable recordkeeping or reporting requirements.

 OBSOLETE PROVISIONS

Provisions that become obsolete before the revision date stated on the cover of each volume are not carried. Code users may find the text of provisions in effect on a given date in the past by using the appropriate numerical list of sections affected. For the period before January 1, 1986, consult either the List of CFR Sections Affected, 1949-1963, 1964-1972, or 1973-1985, published in seven separate volumes. For the period beginning January 1, 1986, a “List of CFR Sections Affected” is published at the end of each CFR volume.

 INCORPORATION BY REFERENCE

What is incorporation by reference? Incorporation by reference was established by statute and allows Federal agencies to meet the requirement to publish regulations in the Federal Register by referring to materials already published elsewhere. For an incorporation to be valid, the Director of the Federal Register must approve it. The legal effect of incorporation by reference is that the material is treated as if it were published in full in the Federal Register (5 U.S.C. 552(a)). This material, like any other properly issued regulation, has the force of law.

What is a proper incorporation by reference? The Director of the Federal Register will approve an incorporation by reference only when the requirements of 1 CFR part 51 are met. Some of the elements on which approval is based are:

(a) The incorporation will substantially reduce the volume of material published in the Federal Register.

(b) The matter incorporated is in fact available to the extent necessary to afford fairness and uniformity in the administrative process.

(c) The incorporating document is drafted and submitted for publication in accordance with 1 CFR part 51.

Properly approved incorporations by reference in this volume are listed in the Finding Aids at the end of this volume.

What if the material incorporated by reference cannot be found? If you have any problem locating or obtaining a copy of material listed in the Finding Aids of this volume as an approved incorporation by reference, please contact the agency that issued the regulation containing that incorporation. If, after contacting the agency, you find the material is not available, please notify the Director of the Federal Register, National Archives and Records Administration, Washington DC 20408, or call (202) 523-4534.

 CFR INDEXES AND TABULAR GUIDES

A subject index to the Code of Federal Regulations is contained in a separate volume, revised annually as of January 1, entitled CFR Index and Finding Aids. This volume contains the Parallel Table of Statutory Authorities and Agency Rules (Table I). A list of CFR titles, chapters, and parts and an alphabetical list of agencies publishing in the CFR are also included in this volume.

An index to the text of “Title 3—The President” is carried within that volume.

The Federal Register Index is issued monthly in cumulative form. This index is based on a consolidation of the “Contents” entries in the daily Federal Register.

A List of CFR Sections Affected (LSA) is published monthly, keyed to the revision dates of the 50 CFR titles.

 REPUBLICATION OF MATERIAL

There are no restrictions on the republication of material appearing in the Code of Federal Regulations.

animals.</SUBJECT> <P>(a) The Commissioner of Food and Drugs has determined that, in order to assure that anthelmintic drugs, including animal feeds bearing or containing such drugs, which do not carry the prescription statement are labeled to provide adequate directions for their effective use, labeling of these anthelmintic drugs shall bear, in addition to other required information, a statement that a veterinarian should be consulted for assistance in the diagnosis, treatment, and control of parasitism.</P> <P>(b) The label and any labeling furnishing or purporting to furnish directions for use, shall bear conspicuously the following statement: “Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism.”<PRTPAGE P="6"/> </P> <P>(c) For drugs covered by approved new animal drug applications, the labeling revisions required for compliance with this section may be placed into effect without prior approval as provided for in § 514.8 (d) and (e) of this chapter. For animal feeds bearing or containing anthelmintic drugs covered by approved applications, the labeling revisions required for compliance with this section may be placed into effect without the submission of supplemental applications as provided for in § 514.9 of this chapter.</P> <P>(d) Labeling revisions required for compliance with this section shall be placed into effect by February 25, 1975, following which, any such drugs that are introduced into interstate commerce and not in compliance with this section will be subject to regulatory proceedings.</P> </SECTION> <SECTION> <SECTNO>§ 500.26</SECTNO> <SUBJECT>Timed-release dosage form drugs.</SUBJECT> <P>(a) Drugs are being offered in dosage forms that are designed to release the active ingredients over a prolonged period of time. There is a possibility of unsafe overdosage or ineffective dosage if such products are improperly made and the active ingredients are released at one time, over too short or too long a period of time, or not released at all. Drugs marketed in this form, which are referred to by such terms as timed-release, controlled-release, prolonged-release, sustained-release, or delayed-release drugs, are regarded as new animal drugs within the meaning of section 201(v) of the Federal Food, Drug, and Cosmetic Act.</P> <P>(b) Timed-release dosage form animal drugs that are introduced into interstate commerce are deemed to be adulterated within the meaning of section 501(a)(5) of the act and subject to regulatory action unless such animal drug is the subject of an approved new animal drug application as required by paragraph (a) of this section.</P> <P>(c) The fact that the labeling of this kind of drug may claim delayed, prolonged, controlled, or sustained-release of all or only some of the active ingredients does not affect the new animal drug status of such articles. A new animal drug application is required in any such case.</P> <P>(d) New animal drug applications for timed-release dosage form animal drugs must contain, among other things, data to demonstrate safety and effectiveness by establishing that the article is manufactured using procedures and controls to ensure release of the total dosage at a safe and effective rate. Data submitted in the new animal drug application must demonstrate that the formulation of the drug and the procedures used in its manufacture will ensure release of the active ingredient(s) of the drug at a safe and effective rate and that these release characteristics will be maintained until the expiration date of the drug. When the drug is intended for use in food-producing animals, data submitted must also demonstrate that, with respect to possible residues of the drug, food derived from treated animals is safe for consumption.</P> <CITA>[42 FR 8635, Feb. 11, 1977, as amended at 60 FR 38480, July 27, 1995]</CITA> </SECTION> <SECTION> <SECTNO>§ 500.27</SECTNO> <SUBJECT>Methylene blue-containing drugs for use in animals.</SUBJECT> <P>(a) New information requires a re- evaluation of the status of drugs containing methylene blue (tetramethylthionine chloride) for oral use in cats or dogs.</P> <P>(1)(i) It has been demonstrated that two orally administered urinary antiseptic-antispasmodic preparations that contained methylene blue cause Heinz body hemolytic anemia in cats when used according to label directions. The specific cause of the reaction was determined to be the methylene blue contained in the preparations. The reaction can be severe enough to cause death of treated animals.</P> <P>(ii) The Heinz body hemolytic anemia reaction to methylene blue has also been demonstrated in dogs under laboratory conditions. The precise mechanism by which methylene blue produces the characteristic erythrocytic inclusion bodies (Heinz bodies) and associated hemolytic anemia is unclear.</P> <P>(2) The effectiveness of orally administered methylene blue as a urinary antiseptic is open to question. It appears that following oral administration, methylene blue is poorly and erratically absorbed and also slowly and erratically excreted in the urine. Studies <PRTPAGE P="7"/>in the dog indicate it is excreted in the urine essentially as leukomethylene blue stabilized in some manner. Methylene blue itself is stepwise demethylated in alkaline solutions (alkaline urine being a frequent consequence of urinary infection) to Azure B, Azure A, and Azure C. The antiseptic efficacy of all of these excretion products is unsubstantiated.</P> <P>(3) In view of the foregoing, the Commissioner has concluded that animal drugs containing methylene blue for oral use in cats or dogs are neither safe nor generally recognized as effective within the meaning of section 201(v) of the act and are therefore considered new animal drugs. Accordingly, all prior formal and informal opinions expressed by the Food and Drug Administration that such drugs are “not new drugs” or “no longer new drugs” are hereby revoked.</P> <P>(b) Animal drugs that contain methylene blue for oral use in cats or dogs and not the subject of an approved new animal drug application (NADA) are deemed to be adulterated under the provisions of section 501(a) (5) and/or (6) and/or misbranded under section 502(a) of the act and subject to regulatory action as of April 10, 1978.</P> <P>(c) Sponsors of animal drugs that contain methylene blue for oral use in cats or dogs and not the subject of an approved new animal drug application (NADA) may submit an application in conformity with § 514.1 of this chapter. Such applications will be processed in accordance with section 512 of the act. Submission of an NADA will not constitute grounds for continued marketing of this drug substance until such application is approved.</P> <P>(d) New animal drug applications required by this regulation pursuant to section 512 of the act shall be submitted to the Food and Drug Administration.

FDA has determined that gentian violet is not exempted from new animal drug status under the “grandfather” provisions of the Drug Amendments of 1962 (21 U.S.C. 342).</P> <CITA>[56 FR 40507, Aug. 15, 1991]</CITA> </SECTION> <SECTION> <SECTNO>§ 500.35</SECTNO> <SUBJECT>Animal feeds contaminated with Salmonella microorganisms.</SUBJECT> <P>(a) Investigations by the Food and Drug Administration, the Centers for Disease Control of the U.S. Public Health Service, the Animal Health Division of the Agricultural Research Service, U.S. Department of Agriculture, and by various State public health agencies have revealed that processed fish meal, poultry meal, meat meal, tankage, and other animal byproducts intended for use in animal feed may be contaminated with Salmonella bacteria, an organism pathogenic to man and animals. Contamination of these products may occur through inadequate heat treatment of the product during its processing or through recontamination of the heat-treated product during a time of improper storage or handling subsequent to processing.</P> <P>(b) Articles used in food for animals are included within the definition of <PRTPAGE P="8"/> <E T="03">food</E> in section 201(f) of the Federal Food, Drug, and Cosmetic Act. Further, Salmonella contamination of such animal feeds having the potentiality for producing infection and disease in animals must be regarded as an adulterant within the meaning of section 402(a) of the act. Therefore, the Food and Drug Administration will regard as adulterated within the meaning of section 402(a) of the act shipments of the following when intended for animal feed and encountered in interstate commerce and found upon examination to be contaminated with Salmonella microorganisms: Bone meal, blood meal, crab meal, feather meal, fish meal, fish solubles, meat scraps, poultry meat meal, tankage, or other similar animal byproducts, or blended mixtures of these.</P> <CITA>[40 FR 13802, Mar. 27, 1975, as amended at 54 FR 18279, Apr. 28, 1989]</CITA> </SECTION> <SECTION> <SECTNO>§ 500.45</SECTNO> <SUBJECT>Use of polychlorinated biphenyls (PCB's) in the production, handling, and storage of animal feed.</SUBJECT> <P>(a) Polychlorinated biphenyls (PCB's) represent a class of toxic industrial chemicals manufactured and sold under a variety of trade names, including: Aroclor (United States); Phenoclor (France); Colphen (Germany); and Kanaclor (Japan). PCB's are highly stable, heat resistant, and nonflammable chemicals. Industrial uses of PCB's include, or did include in the past, their use as electrical transformer and capacitor fluids, heat transfer fluids, hydraulic fluids, plasticizers, and in formulations of lubricants, coatings, and inks. Their unique physical and chemical properties and widespread, uncontrolled industrial applications have caused PCB's to be a persistent and ubiquitous contaminant in the environment, causing the contamination of certain foods. In addition, incidents have occurred in which PCB's have directly contaminated animal feeds as a result of industrial accidents (leakage or spillage of PCB fluids from plant equipment). These accidents in turn cause the contamination of food intended for human consumption (meat, milk, and eggs). Investigations by the Food and Drug Administration have revealed that heat exchange fluids for certain pasteurization equipment used in processing animal feed contain PCB's. Although heat exchange fluids in such equipment are considered to be in <E T="03">closed systems</E>, leakage has occurred that resulted in direct contamination of animal feed with PCB's and subsequently resulted in the transfer of PCB's to human food produced by animals consuming the contaminated feed. The use of PCB-containing coatings on the inner walls of silos has resulted in the contamination of silage which has in turn caused PCB residues in the milk of dairy cows consuming the contaminated silage. Since PCB's are toxic chemicals, the PCB contamination of food as a result of these and other incidents represent a hazard to public health. It is therefore necessary to place certain restrictions on the industrial uses of PCB's in the production, handling, and storage of animal feed.</P> <P>(b) The following special provisions are necessary to preclude accidental PCB contamination of animal feed:</P> <P>(1) Coatings or paints for use on the contact surfaces of feed storage areas may not contain PCB's or any other harmful or deleterious substances likely to contaminate feed.</P> <P>(2) New equipment or machinery for handling or processing feed in or around an establishment producing animal feed shall not contain PCB's.</P> <P>(3) On or before Sept. 4, 1973, the management of establishments producing animal feed shall:</P> <P>(i) Have the heat exchange fluid used in existing equipment or machinery for handling and processing feed sampled and tested to determine whether it contains PCB's, or verify the absence of PCB's in such formulations by other appropriate means. On or before Sept. 4, 1973, any such fluid formulated with PCB's must to the fullest extent possible commensurate with current good manufacturing practices, be replaced with a heat exchange fluid that does not contain PCB's.</P> <P>(ii) Eliminate to the fullest extent possible commensurate with current good manufacturing practices from the animal feed producing establishment any PCB-containing lubricants for equipment or machinery used for handling or processing animal feed.<PRTPAGE P="9"/> </P> <P>(iii) Eliminate to the fullest extent possible commensurate with current good manufacturing practices from the animal feed producing establishment any other PCB-containing materials, whenever there is a reasonable expectation that such materials could cause animal feed to become contaminated with PCB's either as a result of normal use or as a result of accident, breakage, or other mishap.</P> <P>(iv) The toxicity and other characteristics of fluids selected as PCB replacements must be adequately determined so that the least potentially hazardous replacement should be used. In making this determination with respect to a given fluid, consideration should be given to (<E T="03">a</E>) its toxicity; (<E T="03">b</E>) the maximum quantity that could be spilled onto a given quantity of food before it would be noticed, taking into account its color and odor; (<E T="03">c</E>) possible signaling devices in the equipment to indicate a loss of fluid, etc.; (<E T="03">d</E>) and its environmental stability and tendency to survive and be concentrated through the food chain.

This subpart provides an operational definition of no residue and identifies the steps a sponsor of a compound shall follow to secure the approval of the compound. FDA guidelines contain the procedures and protocols FDA recommends for the implementation of this subpart. These guidelines are available from the Dockets Management Branch (HFA-305), Food and Drug Administration, rm. 1-23, 12420 Parklawn Dr., Rockville, MD 20857.

artificial flavor, the flavor shall be so labeled, e.g., <E T="03">natural and artificial strawberry flavor.</E> In cases where the flavor <PRTPAGE P="23"/>contains a solely artificial flavor(s), the flavor shall be so labeled, e.g., <E T="03">artificial strawberry flavor.</E> </P> <P>(h) The label of a food to which flavor is added shall declare the flavor in the statement of ingredients in the following way:</P> <P>(1) Spice, natural flavor, and artificial flavor may be declared as <E T="03">spice, natural flavor,</E> or <E T="03">artificial flavor,</E> or any combination thereof, as the case may be.</P> <P>(2) An incidental additive in a food, originating in a spice or flavor used in the manufacture of the food, need not be declared in the statement of ingredients if it meets the requirements of § 501.100(a)(3).</P> <P>(3) Substances obtained by cutting, grinding, drying, pulping, or similar processing of tissues derived from fruit, vegetable, meat, fish, or poultry, e.g., powdered or granulated onions, garlic powder, and celery powder, are commonly understood by consumers to be food rather than flavor and shall be declared by their common or usual name.</P> <P>(4) Any salt (sodium chloride) used as an ingredient in food shall be declared by its common or usual name <E T="03">salt.</E> </P> <P>(5) Any monosodium glutamate used as an ingredient in food shall be declared by its common or usual name <E T="03">monosodium glutamate.</E> </P> <P>(6) Any pyroligneous acid or other artificial smoke flavors used as an ingredient in a food may be declared as <E T="03">artificial flavor</E> or <E T="03">artificial smoke flavor.</E> No representation may be made, either directly or implied, that a food flavored with pyroligneous acid or other artificial smoke flavor has been smoked or has a true smoked flavor, or that a seasoning sauce or similar product containing pyroligneous acid or other artificial smoke flavor and used to season or flavor other foods will result in a smoked product or one having a true smoked flavor.</P> <P>(i) If the label, labeling, or advertising of a food makes any direct or indirect representations with respect to the primary recognizable flavor(s), by word, <E T="03">vignette</E>, e.g., depiction of a fruit, or other means, or if for any other reason the manufacturer or distributor of a food wishes to designate the type of flavor in the food other than through the statement of ingredients, such flavor shall be considered the characterizing flavor and shall be declared in the following way:</P> <P>(1) If the food contains no artificial flavor which simulates, resembles or reinforces the characterizing flavor, the name of the food on the principal display panel or panels of the label shall be accompanied by the common or usual name of the characterizing flavor in letters not less than one-half the height of the letters used in the name of the food, except that:</P> <P>(i) If the food is one that is commonly expected to contain a characterizing food ingredient, and the food contains natural flavor derived from such ingredient and an amount of characterizing ingredient insufficient to independently characterize the food, or the food contains no such ingredient, the name of the characterizing flavor may be immediately preceded by the word <E T="03">natural</E> and shall be immediately followed by the word <E T="03">flavored</E> in letters not less than one-half the height of the letters in the name of the characterizing flavor.</P> <P>(ii) If none of the natural flavor used in the food is derived from the product whose flavor is simulated, the food in which the flavor is used shall be labeled either with the flavor of the product from which the flavor is derived or as <E T="03">artificially flavored.</E> </P> <P>(iii) If the food contains both a characterizing flavor from the product whose flavor is simulated and other natural flavor which simulates, resembles or reinforces the characterizing flavor, the food shall be labeled in accordance with the introductory text and paragraph (i)(1)(i) of this section and the name of the food shall be immediately followed by the words <E T="03">with other natural flavor</E> in letters not less than one-half the height of the letters used in the name of the characterizing flavor.</P> <P>(2) If the food contains any artificial flavor which simulates, resembles or reinforces the characterizing flavor, the name of the food on the principal display panel or panels of the label shall be accompanied by the common or usual name(s) of the characterizing flavor, in letters not less than one-half the height of the letters used in the name of the food and the name of the <PRTPAGE P="24"/>characterizing flavor shall be accompanied by the word(s) <E T="03">artificial</E> or <E T="03">artificially flavored,</E> in letters not less than one-half the height of the letters in the name of the characterizing flavor.</P> <P>(3) Wherever the name of the characterizing flavor appears on the label (other than in the statement of ingredients) so conspicuously as to be easily seen under customary conditions of purchase, the words prescribed by this paragraph shall immediately and conspicuously precede or follow such name, without any intervening written, printed, or graphic matter, except:</P> <P>(i) Where the characterizing flavor and a trademark or brand are presented together, other written, printed, or graphic matter that is a part of or is associated with the trademark or brand may intervene if the required words are in such relationship with the trademark or brand as to be clearly related to the characterizing flavor; and</P> <P>(ii) If the finished product contains more than one flavor subject to the requirements of this paragraph, the statements required by this paragraph need appear only once in each statement of characterizing flavors present in such food.</P> <P>(iii) If the finished product contains three or more distinguishable characterizing flavors, or a blend of flavors with no primary recognizable flavor, the flavor may be declared by an appropriately descriptive generic term in lieu of naming each flavor.</P> <P>(4) A flavor supplier shall certify, in writing, that any flavor he supplies which is designated as containing no artificial flavor does not, to the best of his knowledge and belief, contain any artificial flavor, and that he has added no artificial flavor to it. The requirement for such certification may be satisfied by a guarantee under section 303(c)(2) of the act which contains such a specific statement. A flavor used shall be required to make such a written certification only where he adds to or combines another flavor with a flavor which has been certified by a flavor supplier as containing no artificial flavor, but otherwise such user may rely upon the supplier's certification and need make no separate certification. All such certifications shall be retained by the certifying party throughout the period in which the flavor is supplied and for a minimum of 3 years thereafter, and shall be subject to the following conditions:</P> <P>(i) The certifying party shall make such certifications available upon request at all reasonable hours to any duly authorized officer, or employee of the Food and Drug Administration or any other employee acting on behalf of the Secretary of Health and Human Services. Such certifications are regarded by the Food and Drug Administration as reports to the government and as guarantees or other undertakings within the meaning of section 301(h) of the act and subject the certifying party to the penalties for making any false report to the government under 18 U.S.C. 1001 and any false guarantee or undertaking under section 303(a) of the act. The defenses provided under section 303(c)(2) of the act shall be applicable to the certifications provided for in this section.</P> <P>(ii) Wherever possible, the Food and Drug Administration shall verify the accuracy of a reasonable number of certifications made pursuant to this section, constituting a representative sample of such certifications, and shall not request all such certifications.</P> <P>(iii) Where no person authorized to provide such information is reasonably available at the time of inspection, the certifying party shall arrange to have such person and the relevant materials and records ready for verification as soon as practicable; provided that, whenever the Food and Drug Administration has reason to believe that the supplier or user may utilize this period to alter inventories or records, such additional time shall not be permitted. Where such additional time is provided, the Food and Drug Administration may require the certifying party to certify that relevant inventories have not been materially disturbed and relevant records have not been altered or concealed during such period.</P> <P>(iv) The certifying party shall provide, to an officer or representative duly designated by the Secretary, such qualitative statement of the composition of the flavor or product covered by the certification as may be reasonably <PRTPAGE P="25"/>expected to enable the Secretary's representatives to determine which relevant raw and finished materials and flavor ingredient records are reasonably necessary to verify the certifications. The examination conducted by the Secretary's representative shall be limited to inspection and review of inventories and ingredient records for those certifications which are to be verified.</P> <P>(v) Review of flavor ingredient records shall be limited to the qualitative formula and shall not include the quantitative formula. The person verifying the certifications may make only such notes as are necessary to enable him to verify such certification. Only such notes or such flavor ingredient records as are necessary to verify such certification or to show a potential or actual violation may be removed or transmitted from the certifying party's place of business: <E T="03">Provided,</E> That, where such removal or transmittal is necessary for such purposes the relevant records and notes shall be retained as separate documents in Food and Drug Administration files, shall not be copied in other reports, and shall not be disclosed publicly other than in a judicial proceeding brought pursuant to the act or 18 U.S.C. 1001.</P> <P>(j) A food to which a chemical preservative(s) is added shall, except when exempt pursuant to § 501.100, bear a label declaration stating both the common or usual name of the ingredient(s) and a separate description of its function, e.g., <E T="03">preservative, to retard spoilage, a mold inhibitor, to help protect flavor</E> or <E T="03">to promote color retention.</E> </P> <CITA>[41 FR 38619, Sept. 10, 1976, as amended at 42 FR 14091, Mar. 15, 1977; 42 FR 15675, Mar. 22, 1977]</CITA> </SECTION> </SUBPART> <SUBPART> <RESERVED>Subparts C-E [Reserved]</RESERVED> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart F—Exemptions From Animal Food Labeling Requirements</HD> <SECTION> <SECTNO>§ 501.100</SECTNO> <SUBJECT>Animal food; exemptions from labeling.</SUBJECT> <P>(a) The following foods are exempt from compliance with the requirements of section 403(i)(2) of the act (requiring a declaration on the label of the common or usual name of each ingredient when the food is fabricated from two or more ingredients).</P> <P>(1) An assortment of different items of food, when variations in the items that make up different packages packed from such assortment normally occur in good packing practice and when such variations result in variations in the ingredients in different packages, with respect to any ingredient that is not common to all packages.

This shall be expressed in the terms of weight, measure, numerical count, or a combination of numerical count and weight or measure. The statement shall be in terms of fluid measure if the food is liquid, or in terms of weight if the food is solid, semisolid, or viscous, or a mixture of solid and liquid; except that such statement may be in terms of dry measure if the food is a fresh fruit, fresh vegetable, or other dry commodity that is customarily sold by dry measure. If there is a firmly established general consumer usage and trade custom of declaring the contents of a liquid by weight, or a solid, semisolid, or viscous product by fluid measure, it may be used. Whenever the Commissioner determines that an existing practice of declaring net quantity of contents by weight, measure, numerical count, or a combination in the case of a specific packaged food does not facilitate value comparisons by consumers and offers opportunity for consumer confusion, he will by regulation designate the appropriate term or terms to be used for such commodity.</P> <P>(b)(1) Statements of weight shall be in terms of avoirdupois pound and ounce.</P> <P>(2) Statements of fluid measure shall be in terms of the U.S. gallon of 231 cubic inches and quart, pint, and fluid ounce subdivisions thereof, and shall:</P> <P>(i) In the case of frozen food that is sold and consumed in a frozen state, express the volume at the frozen temperature.</P> <P>(ii) In the case of refrigerated food that is sold in the refrigerated state, express the volume at 40 °F (4 °C).</P> <P>(iii) In the case of other foods, express the volume at 68° F (20° C).</P> <P>(3) Statements of dry measure shall be in terms of the U.S. bushel of 2,150.42 cubic inches and peck, dry quart, and dry pint subdivisions thereof.</P> <P>(c) When the declaration of quantity of contents by numerical count does not give adequate information as to the quantity of food in the package, it <PRTPAGE P="28"/>shall be combined with such statement of weight, measure, or size of the individual units of the foods as will provide such information.</P> <P>(d) The declaration may contain common or decimal fractions. A common fraction shall be in terms of halves, quarters, eighths, sixteenths, or thirty-seconds; except that if there exists a firmly established general consumer usage and trade custom of employing different common fractions in the net quantity declaration of a particular commodity, they may be employed. A common fraction shall be reduced to its lowest terms; a decimal fraction shall not be carried out to more than two places. A statement that includes small fractions of an ounce shall be deemed to permit smaller variations than one which does not include such fractions.</P> <P>(e) The declaration shall be located on the principal display panel of the label, and with respect to packages bearing alternate principal panels it shall be duplicated on each principal display panel.</P> <P>(f) The declaration shall appear as a distinct item on the principal display panel, shall be separated (by at least a space equal to the height of the lettering used in the declaration) from other printed label information appearing above or below the declaration and (by at least a space equal to twice the width of the letter “N” of the style of type used in the quantity of contents statement) from other printed label information appearing to the left or right of the declaration. It shall not include any term qualifying a unit of weight, measure, or count (such as <E T="03">jumbo quart</E> and <E T="03">full gallon</E>) that tends to exaggerate the amount of the food in the container. It shall be placed on the principal display panel within the bottom 30 percent of the area of the label panel in lines generally parallel to the base on which the package rests as it is designed to be displayed: <E T="03">Provided,</E> That on packages having a principal display panel of 5 square inches or less, the requirement for placement within the bottom 30 percent of the area of the label panel shall not apply when the declaration of net quantity of contents meets the other requirements of this part.</P> <P>(g) The declaration shall accurately reveal the quantity of food in the package exclusive of wrappers and other material packed therewith; provided that in the case of foods packed in containers designed to deliver the food under pressure, the declaration shall state the net quantity of the contents that will be expelled when the instructions for use as shown on the container are followed. The propellant is included in the net quantity declaration.</P> <P>(h) The declaration shall appear in conspicuous and easily legible boldface print or type in distinct contrast (by typography, layout, color, embossing, or molding) to other matter on the package; except that a declaration of net quantity blown, embossed, or molded on a glass or plastic surface is permissible when all label information is so formed on the surface. Requirements of conspicuousness and legibility shall include the specifications that:</P> <P>(1) The ratio of height to width (of the letter) shall not exceed a differential of 3 units to 1 unit (no more than 3 times as high as it is wide).</P> <P>(2) Letter heights pertain to upper case or capital letters. When upper and lower case or all lower case letters are used, it is the lower case letter “o” or its equivalent that shall meet the minimum standards.</P> <P>(3) When fractions are used, each component numeral shall meet one-half the minimum height standards.</P> <P>(i) The declaration shall be in letters and numerals in a type size established in relationship to the area of the principal display panel of the package and shall be uniform for all packages of substantially the same size by complying with the following type specifications:</P> <P>(1) Not less than <FR>1/16</FR> inch in height on packages the principal display panel of which has an area of 5 square inches or less.</P> <P>(2) Not less than <FR>1/8</FR> inch in height on packages the principal display panel of which has an area of more than 5 but not more than 25 square inches.</P> <P>(3) Not less than <FR>3/16</FR> inch in height on packages the principal display panel of which has an area of more than 25 but not more than 100 square inches.</P> <P>(4) Not less than <FR>1/4</FR> inch in height on packages the principal display panel of <PRTPAGE P="29"/>which has an area of more than 100 square inches, except not less than <FR>1/2</FR> inch in height if the area is more than 400 square inches.</P> <FP>Where the declaration is blown, embossed, or molded on a glass or plastic surface rather than by printing, typing, or coloring, the lettering sizes specified in paragraphs (i) (1) through (4) of this section shall be increased by <FR>1/16</FR> of an inch.</FP> <P>(j) On packages containing less than 4 pounds or 1 gallon and labeled in terms of weight or fluid measure:</P> <P>(1) The declaration shall be expressed both in ounces, with identification by weight or by liquid measure and, if applicable (1 pound or 1 pint or more) followed in parentheses by a declaration in pounds for weight units, with any remainder in terms of ounces or common or decimal fractions of the pound (see examples set forth in paragraphs (m) (1) and (2) of this section), or in the case of liquid measure, in the largest whole units (quarts, quarts and pints, or pints, as appropriate) with any remainder in terms of fluid ounces or common or decimal fractions of the pint or quart (see examples in paragraphs (m) (3) and (4) of this section).</P> <P>(2) If the net quantity of contents declaration appears on a random package, that is a package which is one of a lot, shipment, or delivery of packages of the same consumer commodity with varying weights and with no fixed weight pattern, it may, when the net weight exceeds 1 pound, be expressed in terms of pounds and decimal fractions of the pound carried out to not more than two decimal places. When the net weight does not exceed 1 pound, the declaration on the random package may be in decimal fractions of the pound in lieu of ounces (see example in paragraph (m)(5) of this section).</P> <P>(3) The declaration may appear in more than one line. The term <E T="03">net weight</E> shall be used when stating the net quantity of contents in terms of weight. Use of the terms <E T="03">net</E> or <E T="03">net contents</E> in terms of fluid measure or numerical count is optional. It is sufficient to distinguish avoirdupois ounce from fluid ounce through association of terms; for example, <E T="03">Net wt. 6 oz.</E> or <E T="03">6 oz. net wt.</E> and <E T="03">6 fl. oz.</E> or <E T="03">net contents 6 fl. oz.</E> </P> <P>(k) On packages containing 4 pounds or 1 gallon or more and labeled in terms of weight or fluid measure, the declaration shall be expressed in pounds for weight units with any remainder in terms of ounces or common or decimal fraction of the pound, or in the case of fluid measure, it shall be expressed in the largest whole unit (gallons followed by common or decimal fraction of a gallon or by the next smaller whole unit or units (quarts, or quarts and pints)) with any remainder in terms of fluid ounces or common or decimal fractions of the pint or quart (see paragraph (m)(6) of this section).</P> <P>(l) [Reserved]</P> <P>(m) <E T="03">Examples:</E> (1) A declaration of 1<FR>1/2</FR> pounds weight shall be expressed as <E T="03">Net Wt. 24 oz.

Dual or combination declarations of net quantity of contents as provided for in paragraphs (a), (c), and (j) of this section (for example, a combination of net weight plus numerical count, net contents plus dilution directions of a concentrate, etc.) are not regarded as supplemental net quantity statements and may be located on the principal display panel.</P> <P>(p) A separate statement of the net quantity of contents in terms of the metric system is not regarded as a supplemental statement and an accurate statement of the net quantity of contents in terms of the metric system of weight or measure may also appear on the principal display panel or on other panels.</P> <P>(q) The declaration of net quantity of contents shall express an accurate statement of the quantity of contents of the package. Reasonable variations caused by loss or gain of moisture during the course of good distribution practice or by unavoidable deviations in good manufacturing practice will be recognized.

PCB's are highly stable, heat resistant, and nonflammable chemicals. Industrial uses of PCB's include, or did include in the past, their use as electrical transformer and capacitor fluids, heat transfer fluids, hydraulic fluids, and plasticizers, and in formulations of lubricants, coatings, and inks. Their unique physical and chemical properties and widespread, uncontrolled industrial applications have caused PCB's to be a persistent and ubiquitous contaminant in the environment, causing the contamination of certain foods. In addition, incidents have occurred in which PCB's have directly contaminated animal feeds as a result of industrial accidents (leakage or spillage of PCB fluids from plant equipment). These accidents in turn caused the contamination of food products intended for human consumption (meat, milk and eggs). Investigations by the Food and Drug Administration <PRTPAGE P="36"/>have revealed that a significant percentage of paper food-packaging material contains PCB's which can migrate to the packaged food. The origin of PCB's in such material is not fully understood. Reclaimed fibers containing carbonless copy paper (contains 3 to 5 percent PCB's) have been identified as a primary source of PCB's in paper products. Some virgin paper products have also been found to contain PCB's, the source of which is generally attributed to direct contamination from industrial accidents from the use of PCB-containing equipment and machinery in food-packaging manufacturing establishments. Since PCB's are toxic chemicals, the PCB contamination of food-packaging materials as a result of industrial accidents, which can cause the PCB contamination of food, represents a hazard to public health. It is therefore necessary to place certain restrictions on the industrial uses of PCB's in establishments manufacturing food-packaging materials.</P> <P>(b) The following special provisions are necessary to preclude the accidental PCB contamination of food-packaging materials:</P> <P>(1) New equipment or machinery for manufacturing food-packaging materials shall not contain or use PCB's.</P> <P>(2) On or before September 4, 1973, the management of establishments manufacturing food-packaging materials shall:</P> <P>(i) Have the heat exchange fluid used in existing equipment for manufacturing food-packaging materials sampled and tested to determine whether it contains PCB's or verify the absence of PCB's in such formulations by other appropriate means. On or before Sept. 4, 1973, any such fluid formulated with PCB's must to the fullest extent possible commensurate with current good manufacturing practices be replaced with a heat exchange fluid that does not contain PCB's.</P> <P>(ii) Eliminate to the fullest extent possible commensurate with current good manufacturing practices from the establishment any other PCB-containing equipment, machinery and materials wherever there is a reasonable expectation that such articles could cause food-packaging materials to become contaminated with PCB's either as a result of normal use or as a result of accident, breakage, or other mishap.</P> <P>(iii) The toxicity and other characteristics of fluids selected as PCB replacements must be adequately determined so that the least potentially hazardous replacement is used. In making this determination with respect to a given fluid, consideration should be given to (<E T="03">a</E>) its toxicity; (<E T="03">b</E>) the maximum quantity that could be spilled onto a given quantity of food before it would be noticed, taking into account its color and odor; (<E T="03">c</E>) possible signaling devices in the equipment to indicate a loss of fluid, etc.; and (<E T="03">d</E>) its environmental stability and tendency to survive and be concentrated through the food chain. The judgment as to whether a replacement fluid is sufficiently non-hazardous is to be made on an individual installation and operation basis.</P> <P>(c) The provisions of this section do not apply to electrical transformers and condensers containing PCB's in sealed containers.</P> </SECTION> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart B—Tolerances for Unavoidable Poisonous or Deleterious Substances</HD> <SECTION> <SECTNO>§ 509.30</SECTNO> <SUBJECT>Temporary tolerances for polychlorinated biphenyls (PCB's).</SUBJECT> <P>(a) Polychlorinated biphenyls (PCB's) are toxic, industrial chemicals. Because of their widespread, uncontrolled industrial applications, PCB's have become a persistent and ubiquitous contaminant in the environment. As a result, certain foods and animal feeds, principally those of animal and marine origin, contain PCB's as unavoidable, environmental contaminants. PCB's are transmitted to the food portion (meat, milk, and eggs) of food producing animals ingesting PCB contaminated animal feed. In addition, a significant percentage of paper food-packaging materials contain PCB's which may migrate to the packaged food. The source of PCB's in paper food-packaging materials is primarily of certain types of carbonless copy paper (containing 3 to 5 percent PCB's) in waste paper stocks used for manufacturing recycled paper. Therefore, temporary tolerances for residues of PCB's as unavoidable environmental or <PRTPAGE P="37"/>industrial contaminants are established for a sufficient period of time following the effective date of this paragraph to permit the elimination of such contaminants at the earliest practicable time. For the purposes of this paragraph, the term <E T="03">polychlorinated biphenyls (PCB's)</E> is applicable to mixtures of chlorinated biphenyl compounds, irrespective of which mixture of PCB's is present as the residue. The temporary tolerances for residues of PCB's are as follows:</P> <P>(1) 0.2 part per million in finished animal feed for food-producing animals (except the following finished animal feeds: feed concentrates, feed supplements, and feed premixes).</P> <P>(2) 2 parts per million in animal feed components of animal origin, including fishmeal and other by-products of marine origin and in finished animal feed concentrates, supplements, and premixes intended for food-producing animals.</P> <P>(3) 10 parts per million in paper food-packaging material intended for or used with finished animal feed and any components intended for animal feeds. The tolerance shall not apply to paper food-packaging material separated from the food therein by a functional barrier which is impermeable to migration of PCB's.</P> <P>(b) A compilation entitled “Analytical Methodology for Polychlorinated Biphenyls, February 1973” for determining compliance with the tolerances established in this section is available from the Dockets Management Branch, Food and Drug Administration, rm. 1-23, 12420 Parklawn Dr., Rockville, MD 20857.</P> <CITA>[42 FR 52821, Sept. 30, 1977, as amended at 46 FR 8460, Jan. 27, 1981;

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.</P> <P>(b) Based upon an evaluation of the conclusions of said Committee and other relevant material, § 510.112 was published in the <E T="04">Federal Register</E> of August 23, 1966 (31 FR 11141), asking <PRTPAGE P="41"/>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 § 510.112 in the <E T="04">Federal Register</E>.</P> <P>(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.</P> <P>(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.</P> <P>(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 within 180 days after publication of the forthcoming revocation order.</P> <P>(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.</P> <CITA>[40 FR 13807, Mar. 27, 1975, as amended at 54 FR 18280, Apr. 28, 1989; 64 FR 403, Jan. 5, 1999]</CITA> </SECTION> <SECTION> <SECTNO>§ 510.112</SECTNO> <SUBJECT>Antibiotics used in veterinary medicine and for nonmedical purposes; required data.</SUBJECT> <P>(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.</P> <P>(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.</P> <P>(c) The required data shall be submitted within 180 days of the date of publication of this section in the <E T="04">Federal Register</E>; except that in the case of data on intramammary infusion <PRTPAGE P="42"/>preparations the data shall be submitted within 60 days of such publication.

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.

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.</P> </SECTION> <SECTION> <SECTNO>§ 510.455</SECTNO> <SUBJECT>New animal drug requirements regarding free-choice administration in feeds.</SUBJECT> <P>(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.</P> <P>(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 § 510.3(i)). In addition, the exemption from the requirement of an approved medicated feed application provided in § 558.4 of this chapter does not apply to any free-choice medicated feed.</P> <P>(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:</P> <P>(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</P> <P>(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.</P> <P>(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.</P> <P>(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:</P> <P>(1) The formula is the same as the one published in the new animal drug regulations; or</P> <P>(2) The data in a master file have been referenced in an NADA or supplemental NADA; and<PRTPAGE P="47"/> </P> <P>(3) Use of the Type A medicated article in the specific formulation has been approved on the basis that:</P> <P>(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</P> <P>(ii) The medicated feed applicant has written authority to reference a master file that has acceptable data for the formula in question.</P> <APPRO>(Approved by the Office of Management and Budget under control number 0910-0205)</APPRO> <CITA>[51 FR 19827, June 3, 1986]</CITA> </SECTION> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart F—Animal Use Exemptions From Certification and Labeling Requirements</HD> <SECTION> <SECTNO>§ 510.515</SECTNO> <SUBJECT>Animal feeds bearing or containing new animal drugs subject to the provisions of section 512(n) of the act.</SUBJECT> <P>Animal feeds that bear or contain penicillin, chlortetracycline, feed grade zinc bacitracin, and bacitracin methylene disalicylate, with or without added suitable nutritive ingredients are exempt from the certification requirements of section 512 of the act provided they are the subject of and in compliance with regulations for their use in this subchapter E, part 558 of this chapter, or any one of the paragraphs of this section:</P> <P>(a) Where indicated in paragraph (b) of this section it is manufactured with or without one, but only one, of the following ingredients in a quantity, by weight of feed, as hereinafter indicated:</P> <P>(1) Arsanilic acid: Not less than 0.005 percent and not more than 0.01 percent.</P> <P>(2) Sodium arsanilate: Not less than 0.005 percent and not more than 0.01 percent.</P> <P>(3) 3-Nitro-4-hydroxyphenylarsonic acid: Not less than 0.0025 percent and not more than 0.0075 percent except in chicken or turkey feed which shall contain not less than 0.0025 percent and not more than 0.005 percent.</P> <P>(b) It is intended for use in any one of the following conditions set forth in this paragraph:</P> <P>(1) It is intended for use solely in the treatment of chronic respiratory disease (air-sac infection), infectious sinusitis, and blue comb (nonspecific infectious enteritis) in poultry and/or bacterial swine enteritis; its labeling bears adequate directions and warnings for such use; and it contains, per ton of feed, the equivalent of 100 grams of penicillin.

If a danger to the public health exists, however, he shall terminate the exemption forthwith and notify the sponsor of the termination. In such event the sponsor shall have an opportunity for a regulatory hearing before the Food and Drug Administration pursuant to part 16 (see 42 FR 15675, March 22, 1977) of this chapter on the question of whether the exemption should be reinstated.</P> <P>(5) If the Commissioner determines, after the unreliable data submitted by the investigator are eliminated from consideration, that the data remaining are such that a new animal drug application would not have been approved, he will proceed to withdraw approval of the application in accordance with section 512(e) of the act.</P> <P>(6) An investigator who has been determined to be ineligible may be reinstated as eligible to receive investigational-use new animal drugs when the Commissioner determines that he has presented adequate assurance that he will employ such new animal drugs solely in compliance with the exempting regulations in this section for investigational-use new animal drugs.</P> <P>(d) <E T="03">Termination of exemption.</E> If the Commissioner finds that:</P> <P>(1) The sponsor of the investigation has failed to comply with any of the conditions for the exemption established under this section, or</P> <P>(2) The continuance of the investigation is unsafe or otherwise contrary to the public interest or the drug is being or has been used for purposes other than bona fide scientific investigation, he shall first notify the sponsor and invite his immediate correction. If the conditions of the exemption are not immediately met, the sponsor shall have an opportunity for a regulatory hearing before the Food and Drug Administration pursuant of part 16 of this chapter on whether the exemption should be terminated. If the exemption is terminated the sponsor shall recall or have destroyed the unused supplies of the new animal drug.</P> <P>(e) <E T="03">Statements and requests.</E> “Notice(s) of Claimed Investigational Exemption for a New Animal Drug” and requests for authorization to use investigational animals and their products for food should be addressed to the Department of Health and Human Services, Food and Drug Administration, Center for Veterinary Medicine, 7500 Standish Pl., Rockville, MD 20855.</P> <P>(f) <E T="03">Contract research organizations.</E> (1) For purposes of this part and part 514, <E T="03">contract research organization</E> means a person that assumes, as an independent contractor with the sponsor, one or more of the obligations of a sponsor, e.g., design of a protocol, selection or monitoring of investigations, evaluation of reports, and preparation of materials to be submitted to the Food and Drug Administration.</P> <P>(2) A sponsor may transfer responsibility for any or all of the obligations set forth in this part to a contract research organization. Any such transfer shall be in writing and, if not all obligations are transferred, shall describe each of the obligations being assumed by the contract research organization. If all obligations are transferred, a general statement that all obligations have been transferred is acceptable. Any obligation not covered by the written description shall be deemed not to have been transferred.</P> <P>(3) A contract research organization that assumes any obligation of a sponsor shall comply with the specific regulations in this chapter applicable to this obligation and shall be subject to the same regulatory action as a sponsor for failure to comply with any obligation assumed under these regulations. Thus, all references to <E T="03">sponsor</E> in this part apply to a contract research <PRTPAGE P="58"/>organization to the extent that it assumes one or more obligations of the sponsor.</P> <CITA>[40 FR 13823, Mar. 27, 1975, as amended at 41 FR 48268, Nov. 2, 1976; 42 FR 15675, Mar. 22, 1977; 50 FR 7517, Feb. 22, 1985; 50 FR 16668, Apr. 26, 1985; 52 FR 8847, Mar. 19, 1987; 54 FR 18280, Apr. 28, 1989; 57 FR 6475, Feb. 25, 1992; 62 FR 40599, July 29, 1997]</CITA> </SECTION> </PART> <PART> <EAR>Pt. 514</EAR> <HD SOURCE="HED">PART 514—NEW ANIMAL DRUG APPLICATIONS</HD> <CONTENTS> <SUBPART> <HD SOURCE="HED">Subpart A—General Provisions</HD> <SECHD>Sec.</SECHD> <SECTNO>514.1</SECTNO> <SUBJECT>Applications.</SUBJECT> <SECTNO>514.4</SECTNO> <SUBJECT>Substantial evidence.</SUBJECT> <SECTNO>514.6</SECTNO> <SUBJECT>Amended applications.</SUBJECT> <SECTNO>514.7</SECTNO> <SUBJECT>Withdrawal of applications without prejudice.</SUBJECT> <SECTNO>514.8</SECTNO> <SUBJECT>Supplemental new animal drug applications.</SUBJECT> <SECTNO>514.11</SECTNO> <SUBJECT>Confidentiality of data and information in a new animal drug application file.</SUBJECT> <SECTNO>514.12</SECTNO> <SUBJECT>Confidentiality of data and information in an investigational new animal drug notice.</SUBJECT> <SECTNO>514.15</SECTNO> <SUBJECT>Untrue statements in applications.</SUBJECT> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart B—Administrative Actions on Applications</HD> <SECTNO>514.100</SECTNO> <SUBJECT>Evaluation and comment on applications.</SUBJECT> <SECTNO>514.105</SECTNO> <SUBJECT>Approval of applications.</SUBJECT> <SECTNO>514.106</SECTNO> <SUBJECT>Approval of supplemental applications.</SUBJECT> <SECTNO>514.110</SECTNO> <SUBJECT>Reasons for refusing to file applications.</SUBJECT> <SECTNO>514.111</SECTNO> <SUBJECT>Refusal to approve an application.</SUBJECT> <SECTNO>514.115</SECTNO> <SUBJECT>Withdrawal of approval of applications.</SUBJECT> <SECTNO>514.116</SECTNO> <SUBJECT>Notice of withdrawal of approval of application.</SUBJECT> <SECTNO>514.117</SECTNO> <SUBJECT>Adequate and well-controlled studies.</SUBJECT> <SECTNO>514.120</SECTNO> <SUBJECT>Revocation of order refusing to approve an application or suspending or withdrawing approval of an application.</SUBJECT> <SECTNO>514.121</SECTNO> <SUBJECT>Service of notices and orders.</SUBJECT> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart C—Hearing Procedures</HD> <SECTNO>514.200</SECTNO> <SUBJECT>Contents of notice of opportunity for a hearing.</SUBJECT> <SECTNO>514.201</SECTNO> <SUBJECT>Procedures for hearings.</SUBJECT> </SUBPART> <SUBPART> <RESERVED>Subparts D-E[Reserved]</RESERVED> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart F—Judicial Review</HD> <SECTNO>514.235</SECTNO> <SUBJECT>Judicial review.</SUBJECT> </SUBPART> </CONTENTS> <AUTH> <HD SOURCE="HED">Authority: </HD> <P>21 U.S.C. 351, 352, 360b, 371, 379e, 381.</P> </AUTH> <SOURCE> <HD SOURCE="HED">Source: </HD> <P>40 FR 13825, Mar. 27, 1975, unless otherwise noted.</P> </SOURCE> <SUBPART> <HD SOURCE="HED">Subpart A—General Provisions</HD> <SECTION> <SECTNO>§ 514.1</SECTNO> <SUBJECT>Applications.</SUBJECT> <P>(a) Applications to be filed under section 512(b) of the act shall be submitted in the form described in paragraph (b) of this section.

The Food and Drug Administration will take no action against a new animal drug or an applicant solely because changes that have been permitted in a written communication are placed into effect by the applicant prior to his receipt of a written notice of approval of the supplemental new animal drug application.</P> <P>(h) Except as provided in paragraphs (e) and (g) of this section, no provision of this section shall limit the authority of the Secretary or of the Commissioner to suspend or withdraw approval of a new animal drug application in accord with the provisions of section 512(e) of the act or to initiate any other regulatory proceedings with respect to a drug or applicant under provisions of the act.</P> <P>(i) Changes from the conditions of an approved new animal drug application in accord with the provisions of paragraphs (d), (e), and (g) of this section are permitted on the basis of a temporary deferral of final action on the <PRTPAGE P="71"/>supplemental application under the provisions of section 512 (c), (d), or (e) of the act.</P> <P>(j) When an applicant receives written notification from the Food and Drug Administration, under the provisions of paragraph (g) of this section, that he may place into effect changes proposed in a supplemental application without approval of the supplemental application, he may within 30 days submit a written request that the Food and Drug Administration process the supplemental application. In such case, the change shall not be put into effect until approved. Within 180 days of the receipt of such written request, the Food and Drug Administration will approve the supplemental application or furnish notice of an opportunity for a hearing under the provisions of section 512 (d) or (e), or both, of the act on a proposal to refuse approval of the supplemental application or to withdraw approval of the application and supplements thereto.</P> <P>(k) A supplement to an application that became effective prior to October 10, 1962, may include a written statement to the effect that a temporary deferral of final action under the provisions of paragraph (d), (e), or (g) of this section is unacceptable to the applicant and that the applicant requests action as provided in section 512(c) of the act. Final action on such supplemental applications will be expedited in accord with applicable provisions of section 512 of the act and regulations in this subchapter E. In such cases, if the applicant places into effect any of the proposed changes prior to his receipt of a written notice of approval of the supplemental new animal drug application, such action may be regarded by the Food and Drug Administration as a basis for invoking the provisions of section 512(e)(1)(D) of the act; that is, the applicant may be furnished notice of an opportunity for a hearing on a proposal to withdraw approval of the application on the ground that the application contains an untrue statement of a material fact related to the changes from the conditions approved in the application.</P> <P>(l) A supplemental application that contains nonclinical laboratory studies shall include, with respect to each nonclinical study, either a statement that the study was conducted in compliance with the requirements set forth in part 58 of this chapter, or, if the study was not conducted in compliance with such regulations, a brief statement of the reason for the noncompliance.</P> <CITA>[40 FR 13825, Mar. 27, 1975, as amended at 50 FR 7517, Feb. 22, 1985; 50 FR 16668, Apr. 26, 1985; 62 FR 40600, July 29, 1997]</CITA> </SECTION> <SECTION> <SECTNO>§ 514.11</SECTNO> <SUBJECT>Confidentiality of data and information in a new animal drug application file.</SUBJECT> <P>(a) For purposes of this section the <E T="03">NADA file</E> includes all data and information submitted with or incorporated by reference in the NADA, INAD's incorporated into the NADA, supplemental NADA's, reports under §§ 510.300 and 510.301 of this chapter, master files, and other related submissions.

The primary purpose of conducting adequate and well-controlled studies of a new animal drug is to distinguish the effect of the new animal drug from other influences, such as spontaneous change in the course of the disease, normal animal production performance, or biased observation. One or more adequate and well-controlled studies are required to establish, by substantial evidence, that a new animal drug is effective. The characteristics described in paragraph (b) of this section have been developed over a period of years and are generally recognized as the essentials of an adequate and well-controlled study. Well controlled, as used in the phrase adequate and well controlled, emphasizes an important aspect of adequacy. The Food and Drug Administration (FDA) considers these characteristics in determining whether a study is adequate and well controlled for purposes of section 512 of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360b). Adequate and well-controlled studies, in addition to providing a basis for determining whether a new animal drug is effective, may also be relied upon to support target animal safety. The report of an adequate and well-controlled study should provide sufficient details of study design, conduct, and analysis to allow critical evaluation and a determination of whether the characteristics of an adequate and well-controlled study are present.</P> <P>(b) <E T="03">Characteristics</E>. An adequate and well-controlled study has the following characteristics:</P> <P>(1) The protocol for the study (protocol) and the report of the study results (study report) must include a clear statement of the study objective(s).</P> <P>(2) The study is conducted in accordance with an appropriate standard of conduct that addresses, among other issues, study conduct, study personnel, study facilities, and study documentation. The protocol contains a statement acknowledging the applicability of, and intention to follow, a standard of conduct acceptable to FDA. The study report contains a statement describing adherence to the standard.<PRTPAGE P="80"/> </P> <P>(3) The study is conducted with a new animal drug that is produced in accordance with appropriate manufacturing practices, which include, but are not necessarily limited to, the manufacture, processing, packaging, holding, and labeling of the new animal drug such that the critical characteristics of identity, strength, quality, purity, and physical form of the new animal drug are known, recorded, and reproducible, to permit meaningful evaluations of and comparisons with other studies conducted with the new animal drug. The physical form of a new animal drug includes the formulation and physical characterization (including delivery systems thereof, if any) of the new animal drug as presented to the animal. The protocol and study report must include an identification number which can be correlated with the specific formulation and production process used to manufacture the new animal drug used in the study.</P> <P>(4) The study uses a design that permits a valid comparison with one or more controls to provide a quantitative evaluation of drug effects. The protocol and the study report must describe the precise nature of the study design, e.g., duration of treatment periods, whether treatments are parallel, sequential, or crossover, and the determination of sample size. Within the broad range of studies conducted to support a determination of the effectiveness of a new animal drug, certain of the controls listed below would be appropriate and preferred depending on the study conducted:</P> <P>(i) <E T="03">Placebo concurrent control</E>. The new animal drug is compared with an inactive preparation designed to resemble the new animal drug as far as possible.</P> <P>(ii) <E T="03">Untreated concurrent control</E>. The new animal drug is compared with the absence of any treatment. The use of this control may be appropriate when objective measurements of effectiveness, not subject to observer bias, are available.</P> <P>(iii) <E T="03">Active treatment concurrent control</E>. The new animal drug is compared with known effective therapy. The use of this control is appropriate when the use of a placebo control or of an untreated concurrent control would unreasonably compromise the welfare of the animals. Similarity of the new animal drug and the active control drug can mean either that both drugs were effective or that neither was effective. The study report should assess the ability of the study to have detected a difference between treatments. The evaluation of the study should explain why the new animal drugs should be considered effective in the study, for example, by reference to results in previous placebo-controlled studies of the active control.</P> <P>(iv) <E T="03">Historical control</E>. The results of treatment with the new animal drug are quantitatively compared with experience historically derived from the adequately documented natural history of the disease or condition, or with a regimen (therapeutic, diagnostic, prophylactic) whose effectiveness is established, in comparable animals. Because historical control populations usually cannot be as well assessed with respect to pertinent variables as can concurrent control populations, historical control designs are usually reserved for special circumstances. Examples include studies in which the effect of the new animal drug is self-evident or studies of diseases with high and predictable mortality, or signs and symptoms of predictable duration or severity, or, in the case of prophylaxis, predictable morbidity.</P> <P>(5) The study uses a method of selecting animals that provides adequate assurances that the animals are suitable for the purposes of the study. For example, the animals can reasonably be expected to have animal production characteristics typical of the class(es) of animals for which the new animal drug is intended, there is adequate assurance that the animals have the disease or condition being studied, or, in the case of prophylactic agents, evidence of susceptibility and exposure to the condition against which prophylaxis is desired has been provided. The protocol and the study report describe the method of selecting animals for the study.</P> <P>(6) The study uses a method to assign a treatment or a control to each experimental unit of animals that is random and minimizes bias. Experimental units of animals are groups of animals that are comparable with respect to <PRTPAGE P="81"/>pertinent variables such as age, sex, class of animal, severity of disease, duration of disease, dietary regimen, level of animal production, and use of drugs or therapy other than the new animal drug. The protocol and the study report describe the method of assignment of animals to an experimental unit to account for pertinent variables and method of assignment of a treatment or a control to the experimental units. When the effect of such variables is accounted for by an appropriate design, and when, within the same animal, effects due to the test drug can be obtained free of the effects of such variables, the same animal may be used for both the test drug and the control using the controls set forth in paragraph (b)(4) of this section.</P> <P>(7) The study uses methods to minimize bias on the part of observers and analysts of the data that are adequate to prevent undue influences on the results and interpretation of the study data. The protocol and study report explain the methods of observation and recording of the animal response variables and document the methods, such as “blinding” or “masking,” used in the study for excluding or minimizing bias in the observations.</P> <P>(8) The study uses methods to assess animal response that are well defined and reliable. The protocol and study report describe the methods for conducting the study, including any appropriate analytical and statistical methods, used to collect and analyze the data resulting from the conduct of the study, describe the criteria used to assess response, and, when appropriate, justify the selection of the methods to assess animal response.</P> <P>(9) There is an analysis and evaluation of the results of the study in accord with the protocol adequate to assess the effects of the new animal drug. The study report evaluates the methods used to conduct, and presents and evaluates the results of, the study as to their adequacy to assess the effects of the new animal drug. This evaluation of the results of the study assesses, among other items, the comparability of treatment and control groups with respect to pertinent variables and the effects of any interim analyses performed.</P> <P>(c) <E T="03">Field studies</E>. (1) Field conditions as used in this section refers to conditions which closely approximate the conditions under which the new animal drug, if approved, is intended to be applied or administered.</P> <P>(2) Studies of a new animal drug conducted under field conditions shall, consistent with generally recognized scientific principles and procedures, use an appropriate control that permits comparison, employ procedures to minimize bias, and have the characteristics generally described in paragraph (b) of this section. However, because field studies are conducted under field conditions, it is recognized that the level of control over some study conditions need not or should not be the same as the level of control in laboratory studies. While not all conditions relating to a field study need to be or should be controlled, observations of the conditions under which the new animal drug is tested shall be recorded in sufficient detail to permit evaluation of the study. Adequate and well-controlled field studies shall balance the need to control study conditions with the need to observe the true effect of the new animal drug under closely approximated actual use conditions.</P> <P>(d) <E T="03">Waiver</E>. The Director of the Center for Veterinary Medicine (the Director) may, on the Director's own initiative or on the petition of an interested person, waive in whole or in part any of the criteria in paragraph (b) of this section with respect to a specific study. A petition for a waiver is required to set forth clearly and concisely the specific criteria from which waiver is sought, why the criteria are not reasonably applicable to the particular study, what alternative procedures, if any, are to be, or have been employed, and what results have been obtained. The petition is also required to state why the studies so conducted will yield, or have yielded, substantial evidence of effectiveness, notwithstanding nonconformance with the criteria for which waiver is requested.</P> <P>(e) <E T="03">Uncontrolled studies</E>. Uncontrolled studies or partially controlled studies are not acceptable as the sole basis for the approval of claims of effectiveness or target animal safety. Such studies, carefully conducted and documented, <PRTPAGE P="82"/>may provide corroborative support of adequate and well-controlled studies regarding effectiveness and may yield valuable data regarding safety of the new animal drug. Such studies will be considered on their merits in light of the characteristics listed here. Isolated case reports, random experience, and reports lacking the details which permit scientific evaluation will not be considered.</P> <CITA>[63 FR 10770, Mar. 5, 1998]</CITA> </SECTION> <SECTION> <SECTNO>§ 514.120</SECTNO> <SUBJECT>Revocation of order refusing to approve an application or suspending or withdrawing approval of an application.</SUBJECT> <P>The Commissioner, upon his own initiative or upon request of an applicant stating reasonable grounds therefor and if he finds that the facts so require, may issue an order approving an application that previously has had its approval refused, suspended, or withdrawn.</P> </SECTION> <SECTION> <SECTNO>§ 514.121</SECTNO> <SUBJECT>Service of notices and orders.</SUBJECT> <P>All notices and orders under this subchapter E and section 512 of the act pertaining to new animal drug applications shall be served:</P> <P>(a) In person by any officer or employee of the Department designated by the Commissioner; or</P> <P>(b) By mailing the order by certified mail addressed to the applicant or respondent at his last known address in the records of the Food and Drug Administration.</P> </SECTION> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart C—Hearing Procedures</HD> <SECTION> <SECTNO>§ 514.200</SECTNO> <SUBJECT>Contents of notice of opportunity for a hearing.</SUBJECT> <P>(a) The notice to the applicant of opportunity for a hearing on a proposal by the Commissioner to refuse to approve an application or to withdraw the approval of an application will specify the grounds upon which he proposes to issue his order.

(<E T="03">a</E>) Prior to charging vat, empty old contents and thoroughly clean the vat. Dip vats should be calibrated to maintain an accurate dilution. Add water, then drug to the vat according to the dilution rate indicated in the table. Add super phosphate at a rate of 100 pounds per 1,000 gallons of vat solution. Super phosphate is added to control the pH of the solution and ensure vat stability. Super phosphate is usually available at most fertilizer dealers as 0-45-0 or 0-46-0. Stir the dip thoroughly, preferably with a compressed air device; however, any form of thorough mixing is adequate. Re-stir vat contents prior to each use. During the dipping operation, each time the dip's volume is reduced by <FR>1/8</FR> to <FR>1/4</FR> of its initial volume, replenish with water and add the drug at a rate of 1 gallon for each 50 or 200 gallons water added—depending on dilution rate 1:60 or 1:240. Also add super phosphate as necessary to maintain pH between 4.5 and 6.5. Stir well and resume dipping. Repeat replenishment process as necessary. For evaportion, add additional water accordingly. For added water due to rainfall, merely replenish dip with the product according to directions. If overflow occurs, either analyze for drug concentration and adjust accordingly or dispose of vat contents and recharge. Check pH after each addition of water or super phosphate to assure proper pH controls.</P> <P>(<E T="03">b</E>) <E T="03">Dip maintenance</E>. (<E T="03">1</E>) With use of dip vat tester, dipping may continue as long as the drug concentration is maintained between 0.15 and 0.25 percent, and the dip is not too foul for satisfactory use as indicated by foul odor or excessive darkening (i.e., color changes from beige to very dark brown).</P> <P>(<E T="03">2</E>) Without use of dip vat tester, vat should be emptied, cleaned, and recharged each time one of the following occurs: When the dip has been charged for 120 days; when the dip becomes too foul for satisfactory use, within the 120-day limit; if the number of animals dipped equals twice the number of gallons of the initial dip volume, within the 120-day limit.</P> <P>(ii) <E T="03">Spray method</E>. To prepare the spray, mix drug with water according to table and stir thoroughly. Apply the fresh mixture as a high-pressure spray, taking care to wet the skin, not just the hair. Apply to the point of “runoff,” about 1 gallon of diluted spray per adult animal. Lesser amounts will permit runoff for younger animals.</P> <P>(iii) <E T="03">Pour-on method</E>. Dilute the drug with water according to table by slowly adding water to the product while stirring. Apply 1 ounce of the diluted mixture per 100 pounds of body weight (to a maximum of 8 ounces per head) down the center line of the back.</P> <P>(2) <E T="03">Timing of applications for cattle grub control</E>. For optimum cattle grub control, it is important to treat as soon as possible after the heel fly season, before the grub larvae reach the <PRTPAGE P="313"/>gullet or spinal canal, as the rapid kill of large numbers of larvae in these tissues may cause toxic side effects, such as bloat, salivation, staggering, and paralysis.</P> <P>(3) <E T="03">Treatment regimens</E>. (i) Control of scabies mites requires two treatments, 10 to 14 days apart.</P> <P>(ii) Control of Lone Star Ticks and hornflies requires two treatments, 7 days apart.</P> <P>(4) <E T="03">Warnings.</E> The drug is a cholinesterase inhibitor. Do not use this drug on animals simultaneously or within a few days before or after treatment with or exposure to cholinesterase-inhibiting drugs, pesticides, or chemicals. Do not apply within 21 days of slaughter. For use on beef cattle only. Do not treat sick, convalescent, or stressed cattle, or calves less than 3 months old except in Federal or State eradication programs where immediate treatment of all animals in an infested herd is mandatory. Be sure free access to drinking water is available to cattle prior to dipping. Do not dip excessively thirsty animals. Do not dip animals when overheated. Repeat treatment as necessary but not more often than every 7 to 10 days. Treatment for lice, ticks, hornflies, and scabies mites may be made any time of the year except when cattle grub larvae are in the gullet or spinal canal. Treatment for lice, ticks, and scabies mites may be made any time 7 to 10 days following treatment for grubs. Do not treat grubs when the grub larvae are in the gullet or spinal canal. Do not get in eyes, on skin, or on clothing. Do not breathe spray mist. Wear rubber gloves, goggles, and protective clothing. In case of skin contact, wash immediately with soap and water; for eyes, flush with water. Wash all contaminated clothing with soap and hot water before re-use.</P> <P>(d) <E T="03">Related tolerances.</E> See 40 CFR 180.261.</P> <CITA>[40 FR 13873, Mar. 27, 1975, as amended at 46 FR 27914, May 22, 1981; 48 FR 39607, Sept. 1, 1983; 54 FR 51021, Dec. 12, 1989; 61 FR 8873, Mar. 6, 1996; 62 FR 61626, Nov. 19, 1997; 63 FR 5255, Feb. 2, 1998]</CITA> </SECTION> <SECTION> <SECTNO>§ 524.1880</SECTNO> <SUBJECT>Prednisolone-neomycin sulfate ophthalmic ointment.</SUBJECT> <P>(a) <E T="03">Specifications.</E> Prednisolone-neomycin sulfate ophthalmic ointment contains 2 milligrams prednisolone and 5 milligrams neomycin sulfate (equivalent to 3.5 milligrams neomycin base) in each gram of ointment.</P> <P>(b) <E T="03">Sponsor.</E> See No. 017030 in § 510.600(c) of this chapter.</P> <P>(c) <E T="03">Conditions of use.</E> The drug is recommended for use in superficial ocular inflammations or infections limited to the conjunctiva or the anterior segment of the eye of cats and dogs, such as those associated with allergic reactions or gross irritants.

Consideration of an appropriate tolerance for a drug shall result in a conclusion either that:</P> <P>(1) Finite residues will be present in the edible products—in which case a finite tolerance is required; or</P> <P>(2) It is not possible to determine whether finite residues will be incurred but there is reasonable expectation that they may be present—in which case a tolerance for negligible residue is required; or</P> <P>(3) The drug induces cancer when ingested by man or animal or, after tests which are appropriate for the evaluation of the safety of such drug, has been shown to induce cancer in man or animal; however, such drug will not adversely affect the animals for which it is intended, and no residue of such drug will be found by prescribed methods of analysis in any edible portion of such animals after slaughter or in any food yielded by or derived from the living animal—in which case the accepted method of analysis shall be published or cited, if previously published and available elsewhere, in this part; or</P> <P>(4) It may or may not be possible to determine whether finite residues will be incurred but there is no reasonable expectation that they may be present—in which case the establishment of a tolerance is not required; or</P> <P>(5) The drug is such that it may be metabolized and/or assimilated in such form that any possible residue would be indistinguishable from normal tissue constituents—in which case the establishment of a tolerance is not required.</P> <P>(b) No tolerance established pursuant to paragraph (a)(1) of this section will be set at any level higher than that reflected by the permitted use of the drug.</P> <P>(c) Any tolerance required pursuant to this section will, in addition to the toxicological considerations, be conditioned on the availability of a practicable analytical method to determine the quantity of residue. Such method must be sensitive to and reliable at the established tolerance level or, in certain instances, may be sensitive at a higher level where such level is also deemed satisfactory and safe in light of the toxicity of the drug residue and of the unlikelihood of such residue's exceeding the tolerance.</P> </SECTION> </SUBPART> <SUBPART> <HD SOURCE="HED">Subpart B—Specific Tolerances for Residues of New Animal Drugs</HD> <SECTION> <SECTNO>§ 556.20</SECTNO> <SUBJECT>2-Acetylamino-5-nitrothiazole.</SUBJECT> <P>A tolerance of 0.1 part per million is established for negligible residues of 2-<PRTPAGE P="336"/>acetylamino-5-nitrothiazole in the edible tissues of turkeys.</P> </SECTION> <SECTION> <SECTNO>§ 556.30</SECTNO> <SUBJECT>Aklomide.</SUBJECT> <P>Tolerances are established for combined residues of aklomide (2-chloro-4-nitrobenzamide) and its metabolite (4-amino-2-chlorobenzamide) in uncooked edible tissues of chickens as follows:</P> <P>(a) 4.5 parts per million in liver and muscle.</P> <P>(b) 3 parts per million in skin with fat.</P> </SECTION> <SECTION> <SECTNO>§ 556.34</SECTNO> <SUBJECT> Albendazole.</SUBJECT> <P>(a) <E T="03">Acceptable daily intake (ADI)</E>.

The 3,5-DNBA is extracted from the sample with acetone and chloroform and prepared for chromatography by removing the aqueous phase in a separatory funnel and the solvents in a flash evaporator. The extract residue is chromatographed on alumina to remove several lipid components and residues of other drugs. The benzamide eluate is passed through a column of Dowex-50 resin, or equivalent, to remove arylamines; for example, 3-amino-5-nitrobenzamide. The 3,5-DNBA fraction is reduced, after removal of alcohol, with TiCl<E T="22">3</E> in basic solution to an arylamine, presumably 3,5-diaminobenzamide. The reduced fraction is placed on another Dowex-50 column, most of the interfering substances are removed with washings of alcohol and water, and the arylamine residue is eluted with 4<E T="03">N</E> HCl.

Transfer 1.0 milliliter of stock solution D to a 1-dram glass vial, evaporate to a dry residue in a vacuum desiccator at reduced pressure. The residue contains 2 micrograms of zeranol to be used as a calibration standard in operation of the gas chromatograph.</P> <HD SOURCE="HD1">V. <E T="04">Procedure</E> </HD> <P>A. Preparation of glassware: Glassware should be washed in detergent or chromic acid solution to remove contaminants and rinsed in water to remove traces of cleaning agent. Rinse with methanol before using.</P> <P>B. Preparation of sample.</P> <P>1. Collect muscle, liver, kidney, and tripe from a freshly sacrificed animal under the cleanest conditions possible.</P> <P>2. Grind the fresh tissue in a meat grinder, divide into 100-gram portions, and wrap in aluminum foil. Store wrapped tissue in a deep freeze. Fat should be wrapped in foil and stored in deep freeze.</P> <P>C. Extraction procedure for muscle, liver, kidney, and tripe.</P> <P>1. Weight 100 grams of partially thawed tissue into a 250-milliliter homogenizing flask, add 60 milliliters of water, and attach to a Virtis “45” Tissue Mill, or equivalent.</P> <P>2. Mix the materials at 45,000 r.p.m. for 5 minutes to obtain a thin homogenate.</P> <P>3. Transfer the homogenate to a 1-liter, widemouth, freeze drying flask using 10-20 milliliters of water for a rinse.</P> <P>4. Place the flask on its side in a nearly horizontal position in a slurry of dry ice and acetone. Rotate the flask on its side as the homogenate cools to set down a uniform frozen solid layer on the wall of the flask.</P> <P>5. Mount the flask on a Virtis freeze drier, or equivalent, and lyophilize to dry solids. This operation usually requires 20-24 hours. <E T="03">Stopping place.</E> </P> <P>6. Transfer the solid cake to a clean sheet of paper and crumble by hand to a size convenient for transfer to an extraction thimble.</P> <P>7. Transfer the solids to a single thickness 60 x 180 milliliter Soxhlet extraction thimble and compact the solids sufficiently to guarantee complete immersion during solid extraction.</P> <P>8. Transfer 600 milliliters of methanol to a 1-liter pot of a Soxhlet extraction assembly and place the thimble in the extractor. Mount a large glass funnel in the neck of the extractor with the stem extending into the thimble. Rinse the 1-liter freeze drying flask with three 50-milliliter portions of fresh methanol and transfer the rinses through the funnel into the thimble. Mount the condenser in the extractor and extract the solids for 15 hours. The extractor should be heated with the electric heating mantle so that a fill-empty cycle requires 18-24 minutes.</P> <P>9. Drain the methanol from the thimble. Composite the methanol from the extractor and pot in an 800-milliliter beaker.</P> <P>10. Rinse the pot with 10 milliliters of methanol and add to the methanol composite. Transfer 50 milliliters of 2<E T="03">N</E> HCl down the pot side wall, and add to methanol composite. Concentrate to 125 milliliters by boiling on a hot plate.</P> <P>D. Extraction procedure for fat.</P> <P>1. Cut fat into <FR>1/4</FR>-inch cubes. The lyophilization of fat is unnecessary since it is essentially water free.</P> <P>2. Transfer 100 grams of the prepared fat to a 60- x 180-millimeter extraction thimble and extract with 750 milliliters of methanol for 15 hours in the Soxhlet extractor. The extractor should be heated with the electric heating mantle so that a fill-empty cycle requires 18-24 minutes.</P> <P>3. Drain the methanol from the thimble. Composite the methanol from the extractor and pot into an 800-milliliter beaker.</P> <P>4. Rinse the pot with 10 milliliters of methanol and add to the methanol composite. Transfer 50 milliliters of 2<E T="03">N</E> HCl down the pot side wall, and add to methanol composite. Concentrate to 125 milliliters by boiling on a hot plate.</P> <P>E. Solvent partition.</P> <P>1. Transfer the methanol concentrate to a 500-milliliter separatory funnel, identified by number as 1, with 70 milliliters of chloroform rinse and mix.</P> <P>2. Add 300 milliliters of water and without shaking allow liquid phases to separate.</P> <P>3. Withdraw the chloroform layer into a separatory funnel, identified by number as 2, <PRTPAGE P="352"/>containing 100 milliliters of 2 percent aqueous sodium chloride.</P> <P>4. Gently mix the contents of funnel 2 horizontally end to end 30 times and allow phases to separate. Usually about 20 minutes are required to obtain maximum chloroform separation.</P> <P>5. Withdraw the chloroform layer into a beaker.</P> <P>6. Extract with shaking the contents of funnels 1 and 2 successively with three more 50-milliliter portions of chloroform.</P> <P>7. Composite the chloroform extracts and concentrate to 125 milliliters by evaporation on a steam bath and cool to room temperature.</P> <P>8. Transfer the chloroform composite to a 250-milliliter separatory funnel, fitted with a Teflon stopcock, using 10 milliliters of chloroform as a rinse.</P> <P>9. Extract the chloroform with three separate 20-milliliter portions of 1<E T="03">N</E> sodium hydroxide solution retaining the emulsion in the sodium hydroxide phase. Agitation of sodium hydroxide with the chloroform extract for the first time is accompanied by the appearance of emulsion.</P> <P>10. Perform an extraction by gently inverting the closed funnel and returning the funnel to an upright position.</P> <P>11. Repeat phase mixing 30 times per extraction.</P> <P>12. Allow phases to separate for 10 minutes. The time delay allows for gradual dissipation of the emulsion to improve phase separation. The zeranol transfers from the chloroform to the upper sodium hydroxide phase in this operation.</P> <P>13. Composite the sodium hydroxide extracts.</P> <P>14. Wash the sodium hydroxide extract with three 50-milliliter portions of chloroform using the technique as in step 9 and the same 10-minute interval for phase separation. Washing the chloroform removes the emulsion and unwanted impurities from the sodium hydroxide phase.</P> <P>15. Discard the chloroform washes. Transfer the sodium hydroxide extracts to a 250-milliliter beaker. Rinse each separatory funnel with two 5-milliliter portions of water and add to the sodium hydroxide extract. Wash each funnel twice with tap water and twice with distilled water before next use.</P> <P>16. Neutralize the washed sodium hydroxide extract to pH 8.0 by dropwise addition of 3<E T="03">N</E> phosphoric acid using a pH meter for pH detection.</P> <P>17. Transfer the pH 8.0 water extract to a 250-milliliter separatory funnel using 10 to 20 milliliters of water for a rinse.</P> <P>18. Extract the solution with three separate 50-milliliter portions of carbon tetrachloride. The zeranol transfers to the lower carbon tetrachloride phase. Use the same 30-count phase-mixing technique as in step 9 and allow the mixture to stand 5 minutes for phase separation.</P> <P>19. Composite the carbon tetrachloride extracts.</P> <P>20. Extract the carbon tetrachloride composite with two 20-milliliter portions of 1<E T="03">N</E> sodium hydroxide. Zeranol transfers from carbon tetrachloride to the upper sodium hydroxide phase. After phase mixing, allow the mixture to stand 5 minutes for phase separation.</P> <P>21. Composite the sodium hydroxide extracts.</P> <P>22. Wash the extract with two 50-milliliter portions of carbon tetrachloride. Allow the mixture to stand 5 minutes for phase separation. Discard the carbon tetrachloride washes.</P> <P>23. Transfer the sodium hydroxide extract into a 250-milliliter beaker. Rinse the separatory funnel with two 5-milliliter portions of water and add to the sodium hydroxide extract. Wash each funnel twice with tap water and twice with distilled water before next use. Adjust the sodium hydroxide extract to a pH of 9.5 by dropwise addition of 3<E T="03">N</E> phosphoric acid and transfer to a 250-milliliter separatory funnel using 10-20 milliliters of water for a rinse.</P> <P>24. Extract the pH 9.5 water solution with three separate 30-milliliter portions of anhydrous ethyl ether. Allow the mixture to stand 5 minutes for phase separation. The zeranol transfers to the upper ether phase.</P> <P>25. Composite the ether extracts in a 125-milliliter Erlenmeyer flask.</P> <P>26. Reduce the volume of ether to about 1-2 milliliters by evaporation on a hot plate with low heat while removing vapor from top of flask by vacuum aspiration.</P> <P>27. Transfer ether residue to a 1-dram glass vial. Rinse down flask side wall with 1-2 milliliters of fresh ether and transfer to the glass vial.</P> <P>28. Continue evaporation of ether to 0.1 milliliter.</P> <P>29. Place vial in a vacuum desiccator and evaporate residue at line vacuum and room temperature overnight to dryness.</P> <P>30. Close vial with a plastic cap and submit ether residue for preparation of TMS derivative and gas chromatographic assay. <E T="03">Stopping place.</E> </P> <P>F. Gas liquid chromatography.</P> <P>1. Start the gas chromatography and maintain the following operational conditions:</P> <P>Carrier gas pressure: 50 p.s.i. at tank.</P> <P>Carrier gas flow rate: Sufficient to give zeranol derivative peak a retention time of 4-8 minutes.</P> <P>Electrometer range: 10<E T="21">2</E> or 10<E T="21">1</E>.</P> <P>Detector temperature: 325 °C.</P> <P>Injection port temperature: 325 °C.</P> <P>Column temperature: 250°-280 °C., operate isothermally.</P> <P>Recorder sensitivity: 1 millivolt.</P> <P>Recorder chart speed: 1 inch per minute.<PRTPAGE P="353"/> </P> <P>Sample size: 1 microliter to 5 microliters as necessary to give desired peak area for quantitative measurement.</P> <P>Septums: Replace each evening and allow to condition overnight at operational temperature.</P> <P>Flame assembly: Remove silica ash from the flame assembly each week. The flame assembly is removed; the anode, flame jet, and chimney are cleaned with a nylon bristle brush. Water and acetone are drawn through the jet capillary to remove any foreign material.</P> <P>2. Add 0.2 milliliter of silating reagent to the sample or to the zeranol standard.</P> <P>3. Stopper the vial and shake vigorously.</P> <P>4. Warm the vial at 40°-50° C. for a few minutes, then roll the vial on a horizontal plane to insure that all of the interior surfaces of the vial have been in contact with the reagent.</P> <P>5. Let vial stand for 4 hours or overnight in a warm area (40 °C.) to allow reaction to reach completion.</P> <P>6. Place vial in a small padded centrifuge tube and centrifuge to settle the precipitate and insure that all the liquid is at the bottom of the vial.</P> <P>7. Inject 1.0-5.0 microliters of clear solution into the chromatograph. At the beginning of the day's run, make 3-5 injections of a standard to condition the column for that day before taking quantitative data.</P> <P>8. Run known mixtures at the beginning, middle, and end of the day's run over the concentration range of samples to be analyzed to compensate for day-to-day sensitivity fluctuations and drift. If four or less samples are to be run, calibrating at the beginning and end of the run is sufficient.</P> <HD SOURCE="HD1">VI. <E T="04">Calculations</E> </HD> <P>Area values are obtained on known mixtures and samples by multiplying the net peak height by the peak width at half height or by counting squares. Area values obtained on knowns are plotted versus zeranol concentration. Calibration plots indicate a near linear function in the 0-10 microgram range. Area values obtained on samples are converted directly to microgram quantities using the curve. Control tests demonstrated a 70 percent recovery of zeranol from spiked wet beef liver and muscle necessitating a correction factor.</P> <GPH DEEP="36" SPAN="1"> <GID>ER01JA93.411</GID> </GPH> <FP>Where:</FP> <P SOURCE="P-3">0.7=Correction factor for 70 percent recovery.</P> <P SOURCE="P-3">W=Grams of tissue examined.</P> <HD SOURCE="HD1">VII. <E T="04">Recovery Study</E> </HD> <P>A. Fortification of reagent blank.</P> <P>1. For those using this method for the first time either for recovery study or tissue assay, a solvent blank and solvent fortified with zeranol should be processed through the entire procedure. This preliminary operation will establish whether or not the procedure is free from contamination arising from solvents and glassware and demonstrate the level of recovery of the standard zeranol. Level of recovery should be in the same range as the samples.</P> <P>2. Transfer 600 milliliters of methanol to a 1-liter beaker.

The demonstrated instability of these drugs gives rise to the question of the stability of other drugs when added to liquid Type B medicated feeds, except where specific approval has been granted for such use. Therefore, the labeling of a drug to provide for its use in a liquid Type B medicated feed causes the drug to be a new animal drug for such use for which an approved new animal drug application is required pursuant to section 512(b) of the Federal Food, Drug, and Cosmetic Act.</P> <P>(b) The addition of a drug to a liquid Type B medicated feed causes such Type B feed to become an animal feed bearing or containing a new animal drug for which an approved application is required pursuant to section 512(m) of the act.</P> <P>(c) Each drug product, intended for oral administration to animals, which contains any of the drugs listed in paragraph (d) of this section and which bears labeling for its use in animal feed and/or drinking water shall also include in such labeling the following statement: “FOR USE IN ——————— ONLY. NOT FOR USE IN LIQUID TYPE B MEDICATED FEEDS,” the blank being filled in with the words “DRY FEEDS,” “DRINKING WATER,” “DRY FEEDS AND DRINKING WATER” as applicable, unless:</P> <P>(1) Such drug product is the subject of an approved new animal drug application providing for its use in liquid Type B medicated feeds, or;</P> <P>(2) The labeling provisions of this paragraph have been waived on the basis of approval of a petition which includes a copy of the product label; a description of the formulation; and information which establishes that the physical, chemical, or other properties of the particular drug product are such that it cannot reasonably be expected to be diverted for use in liquid Type B medicated feeds. Such petitions shall be submitted to the Food and Drug Administration, Center for Veterinary Medicine, 7500 Standish Pl., Rockville, MD 20855.</P> <P>(d) The labeling provisions of paragraph (c) of this section apply to all forms of bacitracin, oxytetracycline, and chlortetracycline.</P> <P>(e) For any drug which is the subject of an approved new animal drug application, the labeling provisions of paragraph (c) of this section may be implemented without prior approval as provided for in § 514.8(d) and (e) of this chapter.</P> <CITA>[40 FR 13959, Mar. 27, 1975, as amended at 52 FR 2684, Jan. 26, 1987; 57 FR 6475, Feb. 25, 1992]</CITA> </SECTION> <SECTION> <SECTNO>§ 558.15</SECTNO> <SUBJECT>Antibiotic, nitrofuran, and sulfonamide drugs in the feed of animals.</SUBJECT> <P>(a) The Commissioner of Food and Drugs will propose to revoke currently approved subtherapeutic (increased rate of gain, disease prevention. etc.) uses in animal feed of antibiotic and sulfonamide drugs whether granted by approval of new animal drug applications, master files and/or antibiotic or food additive regulations, by no later than April 20, 1975, or the nitrofuran drugs by no later than September 5, 1975, unless data are submitted which resolve conclusively the issues concerning their safety to man and animals and their effectiveness under specific criteria established by the Food and Drug Administration based on the guidelines included in the report of the FDA task force on the use of antibiotics in animal feeds. All persons or firms previously marketing identical, related, or similar products except the nitrofuran drugs not the subject of an approved new animal drug application must submit a new animal drug application by July 19, 1973, or by December 4, 1973, in the case of nitrofuran drugs, if marketing is to continue during the interim. New animal drug entities with antibacterial activity not previously marketed, now pending approval or submitted for approval prior to, on, or following the effective date of this publication, shall satisfy such criteria prior to approval.</P> <P>(b) Any person interested in developing data which will support retaining approval for such uses of such antibiotic, nitrofuran, and sulfonamide <PRTPAGE P="359"/>drugs pursuant to section 512(l) of the Federal Food, Drug, and Cosmetic Act shall submit to the Commissioner the following:</P> <P>(1) By July 19, 1973, records and reports of completed, ongoing, or planned studies, including protocols, on the tetracyclines, streptomycin, dihydrostreptomycin, penicillin, and the sulfonamides; for all other antibiotics by October 17, 1973; and for the nitrofuran drugs by March 4, 1974. The Food and Drug Administration encourages sponsors to consult with the Center for Veterinary Medicine on protocol design and plans for future studies.</P> <P>(2) By April 20, 1974, data from completed studies on the tetracyclines, streptomycin, dihydrostreptomycin, the sulfonamides, and penicillin assessing the effect of the subtherapeutic use of the drug in feed on the salmonella reservoir in the target animal as compared to that in nonmedicated controls. Failure to complete the salmonella studies for any of these drugs by that time will be grounds for proceeding to immediately withdraw approval.</P> <P>(3) By April 20, 1975, data satisfying all other specified criteria for safety and effectiveness, including the effect on the salmonella reservoir for any antibiotic or sulfonamide drugs and by September 5, 1975, for the nitrofuran drugs, approved for subtherapeutic use in animal feeds. Drug efficacy data shall be submitted for any feed-use combination product containing such drug and any feed-use single ingredient antibiotic, nitrofuran, or sulfonamide not reviewed by the National Academy of Sciences—National Research Council, Drug Efficacy Study covering drugs marketed between 1938 and 1962.</P> <P>(4) Progress reports on studies underway every January 1 and July 1 until completion.</P> <P>(c) Failure on the part of any sponsor to comply with any of the provisions of paragraph (b) of this section for any of the antibacterial drugs included in paragraph (b)(1) of this section, or interim results indicating a health hazard, will be considered as grounds for immediately proceeding to withdraw approval of that drug for use in animal feeds under section 512(l) of the act in the case of failure to submit required records and reports and under section 512(e) where new information shows that such drug is not shown to be safe.</P> <P>(d) Criteria based upon the guidelines laid down by the task force may be obtained from the Food and Drug Administration, Center for Veterinary Medicine, 7500 Standish Pl., Rockville, MD 20855.</P> <P>(e) Reports as specified in this section shall be submitted to: Food and Drug Administration, Center for Veterinary Medicine, Office of New Animal Drug Evaluation (HFV-100), 7500 Standish Pl., Rockville, MD 20855.</P> <P>(f) Following the completion of the requirements of paragraphs (a) and (b) of this section and the studies provided for therein:</P> <P>(1) Those antibiotic, nitrofuran, and sulfonamide drugs which fail to meet the prescribed criteria for subtherapeutic uses but which are found to be effective for the therapeutic purposes will be permitted in feed only for high-level, short-term therapeutic use and only by or on the order of a licensed veterinarian.</P> <P>(2) Animal feeds containing antibacterial drugs permitted to remain in use for subtherapeutic purposes shall be labeled to include a statement of the quantity of such drugs.</P> <P>(g) The submission of applications and data required by paragraphs (a) and (b) of this section is not required for the continued manufacture of any Type A medicated article which is produced solely from a Type A article that is in compliance with the requirements of this section: <E T="03">Provided,</E> That the Type A medicated article contains no drug ingredient whose use in or on animal feed requires an approved application pursuant to section 512(m) of the act and/or where the Type A article is approved by regulation in this part.</P> <P>(1) The following antibacterial Type A articles manufactured by the designated sponsors are eligible for interim marketing based on their compliance with the requirements of this section:<PRTPAGE P="360"/> </P> <GPOTABLE CDEF="s75,xs50,xs50,xs50,r75" COLS="5" OPTS="L2,i1"> <BOXHD> <CHED H="1">Drug sponsor</CHED> <CHED H="1">Type A article</CHED> <CHED H="1">Species</CHED> <CHED H="1">Use levels</CHED> <CHED H="1">Indications for use</CHED> </BOXHD> <ROW> <ENT I="01">Pitman-Moore, Inc.</ENT> <ENT>Bacitracin zinc </ENT> <ENT>Chickens, turkeys, swine, pheasants, quail, and cattle </ENT> <ENT>Sec. 558.78 </ENT> <ENT>Sec. 558.78.</ENT> </ROW> <ROW> <ENT I="01">A.

But when the concentration of residue in the processed food when ready to eat is higher than the tolerance prescribed for the raw agricultural commodity, the processed food is adulterated unless the higher concentration is permitted by a tolerance obtained under section 409 of the act. For example, if fruit bearing a residue of 7 parts per million of DDT permitted on the raw agricultural commodity is dried and a residue in excess of 7 parts per million of DDT results on the dried fruit, the dehydrated fruit is adulterated unless the higher tolerance for DDT is authorized by the regulations in this part.

A petition will not be denied, however, by reason of the petitioner's having followed procedures other than those outlined in the publications of the National Academy of Sciences-National Research Council if, from available evidence, the Commissioner finds that the procedures used give results as reliable as, or more reliable than, those reasonably to be expected from the use of the outlined procedures. In reaching a decision, the Commissioner will give due weight to the anticipated levels and patterns of consumption of the additive specified or reasonably inferable. For the purposes of this section, the principles for evaluating safety of additives set forth in the above-mentioned publications will apply to any substance that may properly be classified as a food additive as defined in section 201(s) of the act.</P> <P>(b) Upon written request describing the proposed use of an additive and the proposed experiments to determine its safety, the Commissioner will advise a person who wishes to establish the safety of a food additive whether he believes the experiments planned will yield data adequate for an evaluation of the safety of the additive.</P> </SECTION> <SECTION> <SECTNO>§ 570.30</SECTNO> <SUBJECT>Eligibility for classification as generally recognized as safe (GRAS).</SUBJECT> <P>(a) General recognition of safety may be based only on the views of experts qualified by scientific training and experience to evaluate the safety of substances directly or indirectly added to food. The basis of such views may be either (1) scientific procedures or (2) in the case of a substance used in food prior to January 1, 1958, through experience based on common use in food. General recognition of safety requires common knowledge about the substance throughout the scientific community knowledgeable about the safety of substances directly or indirectly added to food.</P> <P>(b) General recognition of safety based upon scientific procedures shall require the same quantity and quality of scientific evidence as is required to obtain approval of a food additive regulation for the ingredient. General recognition of safety through scientific procedures shall ordinarily be based upon published studies which may be corroborated by unpublished studies and other data and information.</P> <P>(c) General recognition of safety through experience based on common use in food prior to January 1, 1958, may be determined without the quantity or quality of scientific procedures required for approval of a food additive regulation. General recognition of safety through experience based on common use in food prior to January 1, 1958, shall ordinarily be based upon generally available data and information. An ingredient not in common use in food prior to January 1, 1958, may achieve general recognition of safety only through scientific procedures.</P> <P>(d) The food ingredients listed as GRAS in part 582 of this chapter do not include all substances that are generally recognized as safe for their intended use in food. Because of the large number of substances the intended use of which results or may reasonably be expected to result, directly or indirectly, in their becoming a component or otherwise affecting the characteristics of food, it is impracticable to list all such substances that are GRAS. A food ingredient of natural biological origin that has been widely consumed for its nutrient properties in the United States prior to January 1, 1958, without known detrimental effects, which is subject only to conventional <PRTPAGE P="472"/>processing as practiced prior to January 1, 1958, and for which no known safety hazard exists, will ordinarily be regarded as GRAS without specific inclusion in part 582 of this chapter.</P> <P>(e) A food ingredient that is not GRAS or subject to a prior sanction requires a food additive regulation promulgated under section 409 of the act before it may be directly or indirectly added to food.</P> <P>(f) A food ingredient that is listed as GRAS in part 582 of this chapter shall be regarded as GRAS only if, in addition to all the requirements in the applicable regulation, it also meets all of the following requirements:</P> <P>(1) It complies with any applicable specifications, or in the absence of such specifications, shall be of a purity suitable for its intended use.</P> <P>(2) It performs an appropriate function in the food or food-contact article in which it is used.</P> <P>(3) It is used at a level no higher than necessary to achieve its intended purpose in that food or, if used as a component of a food-contact article, at a level no higher than necessary to achieve its intended purpose in that article.</P> <P>(g) New information may at an time require reconsideration of the GRAS status of a food ingredient. Any change in status shall be accomplished pursuant to § 570.38.</P> <P>(h) If a substance is affirmed as GRAS pursuant to § 570.35 and listed in a regulation with no limitation other than good manufacturing practice, it shall be regarded as GRAS if its conditions of use are not significantly different from those reported in the regulation as the basis on which the GRAS status of the substance was affirmed. If the conditions of use are significantly different, such use of the substance may not be GRAS. In such case a manufacturer may not rely on the regulation as authorizing the use but must independently establish that the use is GRAS or must use the substance in accordance with a food additive regulation.</P> <P>(i) If an ingredient is affirmed as GRAS pursuant to § 570.35 and listed in a regulation with specific limitation(s), it may be used in food only within such limitation(s) (including the category of food(s), the functional use(s) of the ingredient, and the level(s) of use). Any use of such and ingredient not in full compliance with each such established limitation shall require a food additive regulation.</P> <P>(j) Pursuant to § 570.35, a food ingredient may be affirmed as GRAS and listed in a regulation for a specific use(s) without a general evaluation of use of the ingredient. In addition to the use(s) specified in the regulation, other uses of such an ingredient may also be GRAS.

as safe for their intended use. However, by way of illustration, the Commissioner regards such common food ingredients as salt, pepper, sugar, vinegar, baking powder, and monosodium glutamate as safe for their intended use. The lists in subparts B through H of this part include additional substances that, when used for the purposes indicated, in accordance with good manufacturing or feeding practice, are regarded by the Commissioner as generally recognized as safe for such uses.</P> <P>(b) For the purposes of this section, good manufacturing or feeding practice <PRTPAGE P="500"/>shall be defined to include the following restrictions:</P> <P>(1) The quantity of a substance added to animal food does not exceed the amount reasonably required to accomplish its intended physical, nutritional, or other technical effect in food; and</P> <P>(2) The quantity of a substance that becomes a component of animal food as a result of its use in the manufacturing, processing, or packaging of food, and which is not intended to accomplish any physical or other technical effect in the food itself, shall be reduced to the extent reasonably possible.</P> <P>(3) The substance is of appropriate grade and is prepared and handled as a food ingredient. Upon request the Commissioner will offer an opinion, based on specifications and intended use, as to whether or not a particular grade or lot of the substance is of suitable purity for use in food and would generally be regarded as safe for the purpose intended, by experts qualified to evaluate its safety.</P> <P>(c) The inclusion of substances in the list of nutrients does not constitute a finding on the part of the Department that the substance is useful as a supplement to the diet for animals.</P> <P>(d) Substances that are generally recognized as safe for their intended use within the meaning of section 409 of the Act are listed in subparts B through H of this part. When the status of a substance has been reevaluated and affirmed as GRAS or deleted from subparts B through H of this part, an appropriate explanation will be noted, e.g., “affirmed as GRAS,” “food additive regulation,” “interim food additive regulation,” or “prohibited from use in food,” with a reference to the appropriate new regulation. Such notation will apply only to the specific use covered by the review, e.g., direct animal food use and/or indirect animal food use and/or animal feed use and will not affect its status for other uses not specified in the referenced regulation, pending a specific review of such other uses.</P> </SECTION> <SECTION> <SECTNO>§ 582.10</SECTNO> <SUBJECT>Spices and other natural seasonings and flavorings.</SUBJECT> <P>Spices and other natural seasonings and flavorings that are generally recognized as safe for their intended use, within the meaning of section 409 of the act, are as follows:</P> <GPOTABLE CDEF="s100,r100" COLS="2" OPTS="L2"> <BOXHD> <CHED H="1">Common name</CHED> <CHED H="1">Botanical name of plant source</CHED> </BOXHD> <ROW> <ENT I="01">Alfalfa herb and seed</ENT> <ENT> <E T="03">Medicago sativa</E> L.</ENT> </ROW> <ROW> <ENT I="01">Allspice</ENT> <ENT> <E T="03">Pimenta officinalis</E> Lindl.</ENT> </ROW> <ROW> <ENT I="01">Ambrette seed</ENT> <ENT> <E T="03">Hibiscus abelmoschus L.</E> </ENT> </ROW> <ROW> <ENT I="01">Angelica</ENT> <ENT> <E T="03">Angelica archangelica</E> L. or other spp. of Angelica.</ENT> </ROW> <ROW> <ENT I="01">Angelica root</ENT> <ENT>Do.</ENT> </ROW> <ROW> <ENT I="01">Angelica seed</ENT> <ENT>Do.</ENT> </ROW> <ROW> <ENT I="01">Angostura (cusparia bark)</ENT> <ENT> <E T="03">Galipea officinalis</E> Hancock.</ENT> </ROW> <ROW> <ENT I="01">Anise</ENT> <ENT> <E T="03">Pimpinella anisum</E> L.</ENT> </ROW> <ROW> <ENT I="01">Anise, star</ENT> <ENT> <E T="03">Illicium verum Hook.</E> f.</ENT> </ROW> <ROW> <ENT I="01">Balm (lemon balm)</ENT> <ENT> <E T="03">Melissa officinalis</E> L.</ENT> </ROW> <ROW> <ENT I="01">Basil, bush</ENT> <ENT> <E T="03">Ocimum minimum</E> L.</ENT> </ROW> <ROW> <ENT I="01">Basil, sweet</ENT> <ENT> <E T="03">Ocimum basilicum L.</E> </ENT> </ROW> <ROW> <ENT I="01">Bay</ENT> <ENT> <E T="03">Laurus nobilis</E> L.</ENT> </ROW> <ROW> <ENT I="01">Calendula</ENT> <ENT> <E T="03">Calendula officinalis</E> L.</ENT> </ROW> <ROW> <ENT I="01">Camomile (chamomile), English or Roman</ENT> <ENT> <E T="03">Anthemis nobilis</E> L.</ENT> </ROW> <ROW> <ENT I="01">Camomile (chamomile), German or Hungarian</ENT> <ENT> <E T="03">Matricaria chamomilla</E> L.</ENT> </ROW> <ROW> <ENT I="01">Capers</ENT> <ENT> <E T="03">Capparis spinosa</E> L.</ENT> </ROW> <ROW> <ENT I="01">Capsicum</ENT> <ENT> <E T="03">Capsicum frutescens</E> L. or <E T="03">Capsicum annuum</E> L.</ENT> </ROW> <ROW> <ENT I="01">Caraway</ENT> <ENT> <E T="03">Carum carvi</E> L.</ENT> </ROW> <ROW> <ENT I="01">Caraway, black (black cumin)</ENT> <ENT> <E T="03">Nigella sativa</E> L.</ENT> </ROW> <ROW> <ENT I="01">Cardamom (cardamon)</ENT> <ENT> <E T="03">Elettaria cardamomum</E> Maton.</ENT> </ROW> <ROW> <ENT I="01">Cassia, Chinese</ENT> <ENT> <E T="03">Cinnamomum cassia</E> Blume.</ENT> </ROW> <ROW> <ENT I="01">Cassia, Padang or Batavia</ENT> <ENT> <E T="03">Cinnamomum burmanni</E> Blume.</ENT> </ROW> <ROW> <ENT I="01">Cassia, Saigon</ENT> <ENT> <E T="03">Cinnamomum loureirii</E> Nees.</ENT> </ROW> <ROW> <ENT I="01">Cayenne pepper</ENT> <ENT> <E T="03">Capsicum frutescens</E> L. or <E T="03">Capsicum annuum</E> L.</ENT> </ROW> <ROW> <ENT I="01">Celery seed</ENT> <ENT> <E T="03">Apium graveolens</E> L.</ENT> </ROW> <ROW> <ENT I="01">Chervil</ENT> <ENT> <E T="03">Anthriscus cerefolium</E> (L.)
