The 2008 Farm Bill amended the Packers and Stockyard Act to require that swine contracts:
• Allow swine growers to cancel growing or production contracts for up to 3 days after signing, or any date specified in the contract or growing arrangement (the contract must disclose method and deadline for cancellation);
• Include a disclosure statement on the first page that clearly states that additional large capital investments may be required of the grower during the term of the contract; and
• Allow growers to opt out of arbitration provisions before entering a contract.
