About USDA

In 1862, when President Abraham Lincoln founded the U.S. Department of Agriculture (USDA), he called it the "people's Department." In Lincoln's day, 58 percent of the people were farmers who needed good seeds and information to grow their crops. Today, USDA continues Lincoln's legacy by serving all Americans. Among other responsibilities, USDA is responsible for the safety of meat, poultry and egg products. It is a research leader in everything from human nutrition to new crop technologies that allow us to grow more food and fiber using less water and pesticides.
