About Modesto Milling

Modesto Milling was established in 1974 as a Dairymen's Co-operative. In 1997, a group of local dairymen convinced the Board of Directors to start manufacturing organic dairy grain mixes. By January 1998, Modesto Milling gained its organic certification from Oregon Tilth of Salem, Oregon, as the first organic grain processor in Central California. Modesto Milling processed, conventional and organic feed until August of 2007, when the Board of Directors voted to convert the mill's manufacturing to 100% organic feed. Ninety-nine percent of the ingredients now in use are organic or naturally mined products.

The mill receives ingredients by both rail and truck. Our 20,000 sq.ft. warehouse has space for finished feed and raw sack ingredients, including many specialty OMRI certified products. Bulk feed makes up a majority of our tonnage. Most customers buy our feed through our growing retail sack and feed store business, but we also sell directly in bulk. As a mill trying to live among giants, we understand the needs of smaller ranches, organic production enthusiasts and entrepreneurs.

Here is an article that covers a small part of our history.

Organic Certifications

Modesto Milling holds organic certifications and does business with vendors who hold organic certifications. Many of our clients insist on our formulations containing certified ingredients, because these certifications help them maintain their own organic certification status.

Here are some of our certifications along with info about the certifying organizations:

USDA Organic Certification

The National Organic Program (NOP) develops, implements, and administers national production, handling, and labeling standards for organic agricultural products. The NOP also accredits the certifying agents (foreign and domestic) who inspect organic production and handling operations to certify that they meet USDA standards.Learn more here.

Oregon Tilth Certification

Oregon Tilth is a nonprofit research and education membership organization dedicated to biologically sound and socially equitable agriculture. Oregon Tilth offers educational events throughout the state of Oregon, and provides organic certification services to organic growers, processors, and handlers internationally. Learn more here.
