If you walk through your house with your shoes on, you may be dragging in all kinds of nasty germs and chemicals from the great outdoors.
The bottoms of your shoes spread many unhealthy agents, from pollen and pesticides on the lawn to salmonella in bird poop. In fact, as many as nine different kinds of pathogens can thrive on shoes, according to a University of Arizona study.
Microbes can survive and even multiply because of nutrient-rich soil and other deposits left on the soles.
Ugh. I am not a germophobe but maybe I'll start taking off my shoes before I enter my residence. Or burn them.
