If I believe this warning... I have committed a criminal act! WTF!!

I've been using Kleenex brand tissues for as long as I have been alive. Just yesterday, I noticed a warning on the bottom of my box of anti-viral Kleenex, which I have highlighted and underlined for your viewing pleasure:

If I take this warning seriously (which I don't), simply using a Kleenex tissue for any other purpose on another part of my anatomy (other than my face), would mean I am in violation of a Federal law! Which law? Can I be arrested for said act? Does it mean I've committed a Misdemeanor, or a Felony... or what? Is Kimberly-Clark freakin' crazy?
