The USDA, or United States Department of Agriculture, is a federal agency responsible for overseeing various aspects of farming, forestry, and food. Established in 1862, its mission includes ensuring food safety, supporting agricultural production, and promoting rural development. The USDA also provides assistance to farmers and ranchers through programs and services. In addition to its agricultural focus, the USDA plays a key role in nutrition and food policy. It develops dietary guidelines and oversees food assistance programs like SNAP (Supplemental Nutrition Assistance Program). The agency also conducts research to improve agricultural practices and sustainability.
