I have never been much of a germaphobe, a little bit with my eldest, but by the time the younger two came, I was much more aware of the issue of the danger to our health due to the environmental chemicals in every day household products. I know I am in the minority (of one?) on this board, but I am really not concerned with germs, not that I would have allowed my baby to be on a public restroom floor. We are the only animals that wash our hands before eating or using the bathroom (no, I am not saying you shouldn't wash your hands after using the bathroom). I just don't believe frequent hand washing does that much to prevent the spread of airborne pathogens and it is yet another tactic to engender fear of disease and sell health harming anti-microbial products. Obviously, I want my doctor to wash his hands prior to operating on me (or anyone else for that matter), and I acknowledge that Ignaz Semmelweis understood that going from cutting up dead bodies decaying with bacterial toxins and then delivering babies without washing their hands killed mothers. I also acknowledge that sanitation and other social improvements had been by far the most significant factor in reduction of mortality from infectious diseases, but living 16 to a room with no flushing toilet or running water, feces and garbage piled two feet high outside their dwelling, and drinking water contaminated with all manner of filth, both organic and industrial, is not the same as the fear of catching a disease unless you are washing your hands constantly or worrying about shoes bringing in germs into your house. (I expect people to take off their shoes when entering my house, but not because I think they would make me sick if they didn't, I just prefer not to have people bring dirt into my home on the bottom of their shoes).
These microbes are part of our microbiome, and only become a problem when the conditions in the body are conducive. My dog licks his privates but to date that practice has never made him sick or anyone one else in the family . His favorite food is a piece of raw chicken that he has buried in the dirt for several days and then revisits it, , it hasn'tt make him or anyone else sick (yes I know dogs have a more acidic digestive system then humans do). What makes dogs sick and susceptible to illness are immune destroying vaccinations, the resultant treatment dished out by vets, and inappropriate nutrition.
