Routinely cleaning wristbands is generally ignored. New research finds 95 percent of wristbands tested were contaminated. Rubber and plastic wristbands had higher bacterial counts, while gold and silver, had little to no bacteria. Bacteria found were common skin residents of the genera Staphylococcus and Pseudomonas, and intestinal organisms of the genera Escherichia, specifically E. coli. Staphylococcus was prevalent on 85 percent of the wristbands; researchers found Pseudomonas on 30 percent of the wristbands; and they found E. coli bacteria on 60 percent of the wristbands, which most commonly begins infection through fecal-oral transmission.
