The Organic Dairy Data Collection Act aims to significantly enhance the availability and quality of data for the organic dairy industry. It directs the Secretary of Agriculture to support regional and national programs focused on collecting and publishing comprehensive cost-of-production data for organic milk, encompassing detailed information on major organic feedstuffs and their prices, both domestic and imported, alongside all other associated production costs. Furthermore, the bill mandates the establishment of an "Organic All Milk Prices Survey" within 90 days of enactment, designed to mirror the existing All Milk Prices Survey. This new survey will gather and report monthly data on the payments organic dairy farmers receive for their milk and the prices for organic milk cows, providing both national and regional insights, specifically for the top six organic dairy producing regions. Finally, within 180 days, the Secretary must publish new or augment existing periodic reports with organic milk data that is equivalent in scope to that reported for conventionally produced milk. These reports are required to include crucial information such as organic cost-of-production by State, regional organic milk production quantities, organic mailbox prices for key regions, and major organic feedstuff prices, utilizing data from various agricultural agencies.
