I did some checking before I started my colony. I know they legal to own, breed, and sell here in Nebraska. I know some places, even states, have made laws about and against them though. Best just to check where you are what laws are about regarding your animals.
Furthermore, as far as I have seen and experienced, my ASFs are clean. I give put all my Breeders through an Ivermectin bath cycle that should rid them of mites and even most internal parasites. Standard procedure with any feeder breeders, I would think.
