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.
