This guide reviews contracts for the sale of organic milk that were used in 2007. All of these contracts required that farmers have organic certification. But all of the contracts also included farm practice requirements that went beyond those required for organic certification. For example, requirements related to access to pasture are often spelled out in greater detail than is currently included in National Organic Program regulations. Additional requirements are generally lawful. Farmers should be sure that they understand how to comply with the additional requirements, and how they will show that they have complied.
