Possession, Use, and Transfer of Select Agents and Toxins

This document completes the biennial review and republication of the lists of biological agents and toxins regulated by the U.S. Department of Health and Human Services (HHS), as well as those biological agents and toxins regulated by both HHS and the U.S. Department of Agriculture (USDA). Because USDA has chosen to no longer regulate ten biological agents and toxins which HHS still believes have the potential to pose a severe threat to public health and safety, we have moved those ten biological agents and toxins from the overlap select agents and toxins section to the HHS select agents and toxins section of the select agent regulations. In a companion document published in this issue of the Federal Register, the USDA has established corresponding final rules regarding the select agents and toxins regulated only by the USDA, as well as those overlap select agents and toxins regulated by both agencies.
