The Federal Select Agent Program (FSAP) is comprised of the Centers for Disease Control and Prevention, the U.S. Division of Select Agents and Toxins (DSAT) and the U.S. Department of Agriculture. The FSAP oversees the possession, use, and transfer of biological select agents and toxins. Every individual or entity that possesses, uses, or transfers these agents or toxins must be registered with the FSAP.

The Select Agent Regulations require the Principal Investigator use “due diligence” when transferring an amount of a HHS select toxin otherwise excluded under the Regulations. This provision requires the Principal Investigator to take reasonable actions to ensure that the recipient:
- Is eligible to receive the select toxin (Principal Investigator, treating physician or veterinarian, or commercial manufacturer or distributor).
- Has a legitimate need (i.e., reasonably justified by a prophylactic, protective, bona fide research, or other peaceful purpose) to handle or use such select toxins.
