A very important thing that we can all do to lower our exposure to toxins - heavy metals, pesticides, etc., is to take off our shoes at the door. A recent study highlighted another great reason to leave our shoes at the door - poop!
The bottoms of our shoes can have fecal matter on them, with especially high levels if you live in a densely populated city such as New York City. The sidewalks have lots of microbes, lots of E.coli! Pet dogs defecate on the sidewalks in NYC, and even if the owners pick up the stools (as they should) - some residue stays. Which then people track into their homes on the bottom of their shoes.
The study found high numbers of microbes on outdoor sidewalks, but also on people’s shoes, indoor floors, and carpets. If you live in New York City and wear your shoes indoors, you will absolutely be contaminating the surfaces with the fecal matter. Not good for young children playing on the floors.
The researchers found that carpeted areas have way, way more fecal matter than bare floors.
