The Supplemental Nutrition Assistance Program (SNAP) is among the oldest enduring federal programs. Now, the Agriculture Department has found a way to help recipients eat well even if they live in what’s known as a food desert: no access to supermarkets or high quality food. Two finalists for Service to America Medals brought SNAP to online food buying. Federal Drive Host Tom Temin spoke with the two Sammies finalists: Lisa Gafaldi, a Senior Technical Adviser to the SNAP program and Shelly Pierce, Director of the SNAP Policy and Innovation Division.
