{"title":"Improving U.S. Biosafety and Biosecurity: Revisiting Recommendations from the Federal Experts Security Advisory Panel and the Fast Track Action Committee on Select Agent Regulations.","authors":"Clint A Haines, Gigi Kwik Gronvall","doi":"10.1089/apb.2022.0025","DOIUrl":"10.1089/apb.2022.0025","url":null,"abstract":"<p><strong>Introduction: </strong>In response to a series of biosafety incidents in 2014, the White House directed two high-level expert committees to analyze biosafety and biosecurity in U.S. laboratories and make recommendations for work with select agents and toxins. Overall, they recommended 33 actions to address areas related to national biosafety, including promoting a culture of responsibility, oversight, outreach and education, applied biosafety research, incident reporting, material accountability, inspection processes, regulations and guidelines, and determining the necessary number of high-containment laboratories in the United States.</p><p><strong>Methods: </strong>The recommendations were collected and grouped into categories previously defined by the Federal Experts Security Advisory Panel and the Fast Track Action Committee.
