The U.S. Department of Agriculture (USDA) develops and executes policy on farming, agriculture, and food. Its aims include meeting the needs of farmers and ranchers, promoting agricultural trade and production, assuring food safety, protecting natural resources, fostering rural communities, and ending hunger in America and abroad.

The USDA employs more than 100,000 employees and has an annual budget of approximately $95 billion. It consists of 17 agencies, including the Animal and Plant Health Inspection Service, the Food and Nutrition Service, and the Forest Service. The bulk of the department's budget goes towards mandatory programs that provide services required by law, such as programs designed to provide nutrition assistance, promote agricultural exports, and conserve our environment. 

The USDA also plays an important role in overseas aid programs by providing surplus foods to developing countries.
