Non-touch fittings in hospitals:: a procedure to eradicate Pseudomonas aeruginosa contamination

Non-touch taps, now common in hospitals, can easily be contaminated with Pseudomonas aeruginosa. We report our experience with 87 non-touch taps in a newly built wing of our teaching hospital contaminated with P. aeruginosa from the central. pipe water system. Serotyping and genotyping of strains revealed genetic diversity of isolates, but also showed that major clones were able to persist for tong periods of time in non-touch taps despite chlorination. It is notoriously difficult to decontaminate such taps with biocides and disinfectants. We describe an easy and economical procedure for the eradication of P. aeruginoso contamination from non-touch taps that does not require their removal. (c) 2005 The Hospital Infection Society.
