This is actually an issue that I personally have with a lot of people who own pets. Any kind of pet.
Animals lack the capacity to be sanitary in any way. So it's up to you to have the sanitary practices (but also don't go overboard).
Your mouth is the main gateway bugs use to get to you. Animals, their body parts, their feces, and their mouths should NOT EVER go near your mouth. Yes this includes dogs. Think about it, what is the one thing that dogs LOVE to do when they come across chicken poop? Yes, the answer is 'eat it'. Now let your dog kiss you, and tada like magic you get sick.
You don't have to lug sanatizer around like a lifeline, or daintily walk a huge circle around chicken-poop, or even put rubber gloves on up to your elbows, just wash your hands when you're done, and don't put them in your mouth before-hand.
Also, no kissing baby animals, no matter how cute they are. All it takes is a chick getting it's head stepped on by another chick with poop encrusted feet (very common event). Put your mouth on that cute chickie head, and again... tada... sick.
I think the moral is that humans just need to keep their mouths to themselves, and stop viewing 'outbreaks' and 'infections' as lurking around every corner. Just be reasonable in what you put your mouth against, and wash your hands. That's it, no magic formula, no bleach, no sanitizer addiction, no plague-masks, no lasers, no deathstars or stasis chambers, or any of that fancy stuff.
