Answer 1

So it doesn’t spread throughout the herd/colony and ruin our entire food supply. There’s also a chance that it can spread to humans. Most of the worst outbreaks come from animals because our immune system cannot handle them. It is only through repetitive close contact that the germ in question can mutate to be carried by humans. Eliminating this possibility is the best option for all parties.
