Answer 1

so that it cannot infect the rest of it, just because its currently not infectious to humans doesnt mean i cannot eventually become dangerous, especially if you give it free reign to spread and roll the dice on the mutation RNG.

even from a practical viewpoint it makes sense ot euthanize them because its better ot lose a few animals than torisk your whole operation or be shut down as a health and safety hazard.
