"The President issued Homeland Security Presidential Directive (HSPD) -9 in 2004 to establish a national policy to defend the food and agriculture systems against terrorist attacks, major disasters, and other emergencies. HSPD-9 assigns various emergency response and recovery responsibilities to the Departments of Agriculture (USDA), Health and Human Services (HHS), Homeland Security (DHS), and others. In addition, Emergency Support Function (ESF) -11 addresses the federal food and agriculture response during emergencies and is coordinated by USDA. GAO was asked to evaluate (1) the extent to which there is oversight of federal agencies' overall progress in implementing HSPD-9; (2) the steps USDA has taken to implement its HSPD-9 responsibilities for response and recovery and challenges, if any; and (3) the circumstances under which USDA has coordinated an ESF-11 response and challenges it faces, if any. GAO reviewed key documents; surveyed states; and interviewed agency, state, and industry officials. "
