USDA Organic Agriculture
USDA is committed to helping organic agriculture grow and thrive. To help meet Secretary Vilsack’s goal of increasing the number of certified organic operations, USDA is delivering results through its many programs which serve the growing organic sector. October 2012 marked the 10th anniversary of the USDA Organic Seal, and has become a leading global standard.
