Staphylococcus aureus cultures from name badge lanyards were phenotypically and genotypically indistinguishable from the wearer's nasal carrier strains by pulsed-field gel electrophoresis and antibiogram. Lanyards had a mean age of 22 months and hygiene was poor with only 9% ever having been laundered. Molecular analysis showed that 26% of S. aureus nasal carriers shared an indistinguishable strain on their lanyard. Lanyards should not be recommended for staff in frontline clinical care.
