7 U.S. Code § 196 - Statutory trust established; livestock
It is hereby found that a burden on and obstruction to commerce in livestock is caused by financing arrangements under which packers encumber, give lenders security interest in, or place liens on, livestock purchased by packers in cash sales, or on inventories of or receivables or proceeds from meat, meat food products, or livestock products therefrom, when payment is not made for the livestock and that such arrangements are contrary to the public interest. This section is intended to remedy such burden on and obstruction to commerce in livestock and protect the public interest.
All livestock purchased by a packer in cash sales, and all inventories of, or receivables or proceeds from meat, meat food products, or livestock products derived therefrom, shall be held by such packer in trust for the benefit of all unpaid cash sellers of such livestock until full payment has been received by such unpaid sellers:
For the purpose of this section, a cash sale means a sale in which the seller does not expressly extend credit to the buyer.
