For eggs which have moved or are moving in interstate or foreign commerce, (1) no State or local jurisdiction may require the use of standards of quality, condition, weight, quantity, or grade which are in addition to or different from the official Federal standards, (2) with respect to egg handlers specified in paragraphs (1) and (2) of section 1034(e) of this title, no State or local jurisdiction may impose temperature requirements pertaining to eggs packaged for the ultimate consumer which are in addition to, or different from, Federal requirements, and (3) no State or local jurisdiction other than those in noncontiguous areas of the United States may require labeling to show the State or other geographical area of production or origin: Provided, however, That this shall not preclude a State from requiring that the name, address, and license number of the person processing or packaging eggs, be shown on each container. Labeling, packaging, or ingredient requirements, in addition to or different than those made under this chapter, the Federal Food, Drug, and Cosmetic Act [21 U.S.C. 301 et seq.] and the Fair Packaging and Labeling Act [15 U.S.C. 1451 et seq.], may not be imposed by any State or local jurisdiction, with respect to egg products processed at any official plant in accordance with the requirements under this chapter and such Acts. However, any State or local jurisdiction may exercise jurisdiction with respect to eggs and egg products for the purpose of preventing the distribution for human food purposes of any such articles which are outside of such a plant and are in violation of any of said Federal Acts or any State or local law consistent therewith. Otherwise the provisions of this chapter shall not invalidate any law or other provisions of any State or other jurisdiction in the absence of a conflict with this chapter.
