21 U.S.C. § 607

(a) Labeling receptacles or coverings of meat or meat food products inspected and passed; supervision by inspectors When any meat or meat food product prepared for commerce which has been inspected as hereinbefore provided and marked “Inspected and passed” shall be placed or packed in any can, pot, tin, canvas, or other receptacle or covering in any establishment where inspection under the provisions of this chapter is maintained, the person, firm, or corporation preparing said product shall cause a label to be attached to said can, pot, tin, canvas, or other receptacle or covering, under the supervision of an inspector, which label shall state that the contents thereof have been “inspected and passed” under the provisions of this chapter; and no inspection and examination of meat or meat food products deposited or inclosed in cans, tins, pots, canvas, or other receptacle or covering in any establishment where inspection under the provisions of this chapter is maintained shall be deemed to be complete until such meat or meat food products have been sealed or inclosed in said can, tin, pot, canvas, or other receptacle or covering under the supervision of an inspector. (b) Information on articles or containers; legible form All carcasses, parts of carcasses, meat and meat food products inspected at any establishment under the authority of this subchapter and found to be not adulterated, shall at the time they leave the establishment bear, in distinctly legible form, directly thereon or on their containers, as the Secretary may require, the information required under paragraph (n) of section 601 of this title . (c) Labeling: type styles and sizes; definitions and standards of identity or composition; standards of fill of container; consistency of Federal and Federal-State standards The Secretary, whenever he determines such action is necessary for the protection of the public, may prescribe: (1) the styles and sizes of type to be used with respect to material required to be incorporated in labeling to avoid false or misleading labeling in marketing and labeling any articles or animals subject to this subchapter or subchapter II of this chapter; (2) definitions and standards of identity or composition for articles subject to this subchapter and standards of fill of container for such articles not inconsistent with any such standards established under the Federal Food, Drug, and Cosmetic Act [ 21 U.S.C. 301 et seq.], and there shall be consultation between the Secretary and the Secretary of Health and Human Services prior to the issuance of such standards under either Act relating to articles subject to this chapter to avoid inconsistency in such standards and possible impairment of the coordinated effective administration of these Acts. There shall also be consultation between the Secretary and an appropriate advisory committee provided for in section 661 of this title , prior to the issuance of such standards under this chapter, to avoid, insofar as feasible, inconsistency between Federal and State standards. (d) Sales under false or misleading name, other marking or labeling or in containers of misleading form or size; trade names, and other marking, labeling, and containers approved by Secretary No article subject to this subchapter shall be sold or offered for sale by any person, firm, or corporation, in commerce, under any name or other marking or labeling which is false or misleading, or in any container of a misleading form or size, but established trade names and other marking and labeling and containers which are not false or misleading and which are approved by the Secretary are permitted. (e) Use withholding directive respecting false or misleading marking, labeling, or container; modification of false or misleading matter; hearing; withholding use pending proceedings; finality of Secretary’s action; judicial review; application of section 194 of title 7 If the Secretary has reason to believe that any marking or labeling or the size or form of any container in use or proposed for use with respect to any article subject to this subchapter is false or misleading in any particular, he may direct that such use be withheld unless the marking, labeling, or container is modified in such manner as he may prescribe so that it will not be false or misleading. If the person, firm, or corporation using or proposing to use the marking, labeling or container does not accept the determination of the Secretary, such person, firm, or corporation may request a hearing, but the use of the marking, labeling, or container shall, if the Secretary so directs, be withheld pending hearing and final determination by the Secretary. Any such determination by the Secretary shall be conclusive unless, within thirty days after receipt of notice of such final determination, the person, firm, or corporation adversely affected thereby appeals to the United States court of appeals for the circuit in which such person, firm, or corporation has its principal place of business or to the United States Court of Appeals for the District of Columbia Circuit. The provisions of section 194 of title 7 shall be applicable to appeals taken under this section. (f) Lamb and mutton The Secretary, consistent with United States international obligations, shall establish standards for the labeling of sheep carcasses, parts of sheep carcasses, sheepmeat, and sheepmeat food products.
