Abstract

Pseudomonas aeruginosa infections have been linked to contaminated hospital taps, highlighting the potential for tap outlet fittings (OF) to harbour biofilm.

Suggested interventions include flushing regimens and alternative OF designs.|To investigate the transfer of P. aeruginosa from a contaminated cleaning cloth to conventional and 'antimicrobial/antibiofilm' OFs and to determine whether this contamination persists and/or leads to contamination of tap water.|Microfibre cloths contaminated with P. aeruginosa (10|The median number of P. aeruginosa transferred from cloth to OF was 5.7 × 10|Contaminated cleaning cloths may transfer P. aeruginosa to OFs, leading to contamination of tap water.
