Explanation:
United States Department of Agriculture ( USDA) is a federal agency in the United States which was founded by Abraham Lincoln. This agency plays a major role in the regulation and maintenance of farming, ranching, and forestry industries, as well as regulating aspects of food quality & safety. The agencies established under the USDA includes:
