This bill proposes amendments to the Agricultural Marketing Act of 1946, specifically targeting dairy product reporting requirements. It mandates that dairy manufacturers, already subject to reporting, must now also provide detailed production cost and product yield information for all products processed within their facilities. This new data collection aims to increase transparency regarding the economics of dairy processing. The bill further requires the Secretary of Agriculture to compile and publish a comprehensive report containing this processing cost and yield information every two years, beginning three years after the bill's enactment, to provide greater insight into the factors influencing milk pricing.
