Possession, Use, and Transfer of Select Agents and Toxins; Biennial Review of the List of Select Agents and Toxins and Enhanced Biosafety Requirements. Final rule.

In accordance with the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (the Bioterrorism Response Act), the Centers for Disease Control and Prevention (CDC) in the Department of Health and Human Services (HHS) has reviewed the list of biological agents and toxins that have the potential to pose a severe threat to public health and safety. Following the review, HHS has decided: Not to finalize the proposed changes to the list of select agents and toxins at this time; to finalize provisions to address toxin permissible limits and the inactivation of select agents; to finalize specific provisions to the section of the regulations addressing biosafety; and to clarify regulatory language concerning security, training, incident response, and records. In a companion document published in this issue of the Federal Register, the U.S. Department of Agriculture (USDA) has made parallel regulatory changes.
