American researchers warn that wearing flip-flops may increase your risk of illness from bacterial exposure.
In a revealing study, participants walked New York streets in flip-flops for four days. Lab tests uncovered more than 18,000 bacteria on the footwear.
One researcher explained, "After wearing slippers for three months, 93 percent contain bacteria from feces and 20 percent contain E. coli bacteria."
While many bacteria are harmless, some can be very dangerous. They pose a serious threat if they enter the bloodstream through a small foot wound, potentially causing severe illness.
