Resource | Research and Data | Payment Accuracy and Program Integrity The Extent of Trafficking in The Food Stamp Program: 1999 - 2002

Food stamps are intended for food. When individuals sell their benefits for cash it violates the spirit and intent of the Food Stamp Program as well as the law. This practice, known as trafficking, diverts food stamp benefits away from their purpose. It reduces intended nutritional assistance and undermines public perceptions of the integrity and utility of the program. To combat trafficking, the Food and Nutrition Service conducts undercover investigations of authorized food stores. In addition, the agency has developed powerful new EBT-based administrative tools to identify and sanction traffickers.
