Norm, I don't know. Medicating cattle is introducing drugs into the food supply. The fact that it is over the counter may mean it is easier to get approved, but for something to be effective it often has negative effects if consumed on a regular basis or in too large of amounts. So the FDA is pretty careful about that subject.

Nisin is already approved as a food preservative, so I think approval is more likely. Nisin is the active ingredient in MastOut.

What is the active ingredient in the spray?
