Which of the following agency combinations is responsible for the safety of feed ingredients?

The correct choice indicates that the FDA and FSIS are the key agencies responsible for ensuring the safety of feed ingredients. The FDA (Food and Drug Administration) plays a crucial role in regulating animal feed, including the approval of feed additives, monitoring feed safety, and enforcing compliance with feed safety standards. Specifically, the FDA's Center for Veterinary Medicine oversees the regulation of animal drugs and feed ingredients.
