Where in the Constitution does it give the FedGov the power to run an Agency like the FDA?

Probably stems from the Wickard V Filburn case that destroyed the interstate commerce clause. Because of that decision, the fedgov can regulate, ban, or control anything it likes, interstate commerce or not, and uses the necessary and proper clause to do so.
