Yes, I have heard that. I'm sure they carry some nasty parasites too.
I just read something I didn't know about coons. I know most of the diseases they carry & can transmit to other living things, but I didn't know about roundworm. The eggs of this worm are so light, they can become airborne. Real bad news! By inhaling them, they can hatch & migrate to your brain & eyes. Lovely. Stay away from coon poop! Problems (& deaths) came about through folks who kept them as pets & their little ones got to chewing the coon bedding. Ewwww! Then of course there's salmonella, rabies & leptospirosis. All transmittable to humans & other animals alike. Anyway, just thought I'd share this little nature factoid with you all, in case you didn't know this already.
