Is this like learning that the splash from your toilet bowl sprinkles a bit of water on your toothbrush? Essentially a pure infohazard that makes tour life worse with no benefit?
Just like the bacteria in drinking water, you can't see it, taste it or perceive it in any way and it poses no relevant health risks. Your bathroom is flooded with poop particles even if you close the lid before flushing. It's just a fun fact and nothing to worry about, really.
The entire world is covered in a fine layer of poo particles. Really, anything that isn't covered in poo is the outlier and ought to be highly suspicious.
and from what i can tell it seems like you'd just develop severe allergies and other health issues if you somehow managed to permanently sterilize your skin and everything around you
