USDA recently issued a voluntary standard for grass-fed meat marketing claims. The grass-fed standard states that grass and/or forage must be the sole components of the grass-fed animal's diet during its lifetime, with the exception of milk consumed prior to weaning. Animals cannot be fed grain or grain byproducts and must have continuous access to pasture during the growing season. The USDA Agricultural Marketing Service (AMS) will complete an audit of the production process to verify the 100%-grass-fed designation. The producer must be able to verify for AMS that the requirements are being met through a detailed, documented quality management system. Learn more at
