In order to prevent the waste of commodities whether in private stocks or acquired through price-support operations by the Commodity Credit Corporation before they can be disposed of in normal domestic channels without impairment of the price-support program or sold abroad at competitive world prices, the Commodity Credit Corporation is authorized, on such terms and under such regulations as the Secretary of Agriculture may deem in the public interest: (1) upon application, to make such commodities available to any Federal agency for use in making payment for commodities not produced in the United States; (2) to barter or exchange such commodities for strategic or other materials as authorized by law; (3) in the case of food commodities to donate such commodities to the Bureau of Indian Affairs and to such State, Federal, or private agency or agencies as may be designated by the proper State or Federal authority and approved by the Secretary, for use in the United States in nonprofit school-lunch programs, in nonprofit summer camps for children, in the assistance of needy persons, and in charitable institutions, including hospitals and facilities, to the extent that they serve needy persons (including infants and children). In the case of clause (3) the Secretary shall obtain such assurance as he deems necessary that the recipients thereof will not diminish their normal expenditures for food by reason of such donation. In order to facilitate the appropriate disposal of such commodities, the Secretary may from time to time estimate and announce the quantity of such commodities which he anticipates will become available for distribution under clause (3). The Commodity Credit Corporation may pay, with respect to commodities disposed of under this subsection, reprocessing, packaging, transporting, handling, and other charges accruing up to the time of their delivery to a Federal agency, or to the designated State or private agency. In addition, in the case of food commodities disposed of under this subsection, the Commodity Credit Corporation may pay the cost of processing such commodities into a form suitable for home or institutional use, such processing to be accomplished through private trade facilities to the greatest extent possible. For the purpose of this subsection the terms “State” and “United States” include the District of Columbia and any Territory or possession of the United States. Dairy products acquired by the Commodity Credit Corporation through price support operations may, insofar as they can be used in the United States in nonprofit school lunch and other nonprofit child feeding programs, in the assistance of needy persons, and in charitable institutions, including hospitals, to the extent that needy persons are served, be donated for any such use prior to any other use or disposition. Notwithstanding any other provision of law, such dairy products may be donated for distribution to needy households in the United States and to meet the needs of persons receiving nutrition assistance under the Older Americans Act of 1965 [42 U.S.C. 3001 et seq.].
