The main purpose of the Fair Milk Pricing for Farmers Act is to improve transparency in the dairy industry by requiring manufacturers to report their processing costs. This aims to ensure fair pricing for dairy farmers and enhance market stability. Key provisions of the Act include a requirement for dairy manufacturers to report detailed information about their production costs and product yields. This information must be provided for all products processed at the same facility. The Secretary of Agriculture is tasked with determining the specifics of these reporting requirements.
