Select Agent Program

Intiated in 1996 with the Antiterrorism and Effective Death Penalty Act, and bolstered by the USA Patriot Act of 2001, and the Public Health Security and Bioterrorism Preparedness and Response Act of 2002, the National Select Agent Registry (NSAR) Program oversees the possession, use and transfer of biological select agents and toxins that have the potential to pose a severe threat to public or environmental health. Possession of the specified agents or toxins without registration carries severe civil and criminal penalties.
