In January 2011, the Food Safety Modernization Act (FSMA) became law in the United States. With roughly 15 percent of the U.S. food supply imported, this law was intended to strengthen the food safety system. Previously, the Public Health Security and Bioterrorism Preparedness Response Act had been signed into law following the events of Sept. 11, 2001. It gave the Food and Drug Administration (FDA) the detention authority over food items if there is a credible threat of serious health consequences or death.
