US Department of Defense
The Department of Defense has several units working on food-related diseases and prevention within the department. They are the United States Army Veterinary Crops; the United States Army Center for Health Promotion and Preventive Medicine; the United States Air Force Biomedical Science Corps; and other military agencies who are involved in public health training, food safety, epidemiology, inspections, testing of food, and reviewing processing and delivery systems of food. Preventive Medicine/ Environmental Health Officers conduct investigations of foodborne disease throughout the world.
US Department of Homeland Security
The Department of Homeland Security under Presidential Directive 9: Defense of the United States Agriculture and Food, 2004, established a national policy to defend the agriculture and food system against terrorist attacks, major disasters, and other emergencies. It was noted that the United States agriculture and food systems were vulnerable to disease, pests, and poisonous agents occurring naturally, unintentionally introduced into the food supply, or intentionally delivered as an act of terrorism. The fact that the entire food system is extensive, open, diverse, and very complex, making it an easy target for terrorists, could have serious consequences.
