UK households are being warned that wearing outdoor shoes indoors could pose serious health risks, potentially even shortening lifespan. Research shows footwear can harbour hundreds of thousands of bacteria, including E. coli and Clostridium difficile, which are linked to infections.
A University of Arizona study found that 96% of shoe soles carried coliform bacteria, and 27% had E. coli. Another study detected an average of 421,000 bacteria on a typical shoe, with up to 99% transferring to clean floors within a few steps.
Health experts caution that shoes can also carry MRSA, pesticides, lead, and other pollutants from public places like shopping centres and hospital car parks. These contaminants can spread to carpets and rugs, where children crawling or playing can pick them up.
Life insurance firm Life Pro recommends removing shoes at the door, using indoor-only slippers or socks, and providing guests with fresh socks or slippers. Regular vacuuming and mopping of high-traffic areas can also help reduce germ buildup.
