According to a recent University of Houston study, more than 26% of shoes worn inside the home are contaminated with Clostridium difficile (C. diff), a bacterium that can cause stomach pain and explosive diarrhea. In a separate study from the University of Arizona, researchers found that 96% of shoe soles also contain fecal bacteria. Gross.
Beyond being utterly disgusting, these stats are especially concerning if you have kids or an elderly person in your household.
Irwin Stromeyer, owner of Sterile Space Infection Defense, a company that offers a range of infection control services, pointed out:
After all, think about what what those shoes encounter when you’re outside. City dwellers, in particular, are likely stepping on “animal feces, food garbage, people’s spit and nasal discharge, perhaps some vomit, gasoline, oil, pesticides, fertilizer, and a thousand other biological materials.
