Summary: The recent outbreak of Pseudomonas aeruginosa in a neonatal unit in Northern Ireland has highlighted once again the imperative of a safe patient environment (Burns and Feeley, 2012). If water is not safe, then how can we have safe hospitals? This Outbreak column reviews some of the recent reports of outbreaks of P. aeruginosa and other Gram negative waterborne organisms, which highlight that it is not just the water coming in through the tap that is a cause for concern. The problem extends to the water outlets (wash-hand basins, sinks, showers and taps) themselves that can become a nidus for ongoing dissemination, and finally, to the clinical practices that complete the transmission pathway from sink organisms to patient infections. In addition, these recent outbreak reports demonstrate that our current opinions on what an optimally designed infection prevention healthcare environment should look like may be erroneous. The many outbreaks of P. aeruginosa reported in the literature from exogenous sources are not discussed here. Pseudomonas aeruginosa lives in water and soil but it can also be a human commensal. The tap water coming into hospitals is not, and never can be, sterile. What is crucial is that the journey of tap water through hospitals. water pipework systems does not encourage the growth of opportunistic pathogens in biofilms. It is the intermittent sloughing off of organisms in biofilm that presents undetectable spikes or continuous infection risks where opportunistic pathogens are concerned. As P. aeruginosa is an opportunistic pathogen, for infection to happen there needs to be an accompanying transmission pathway from the source (water/tap/drain) to the patient; there must also be a susceptible host and a .way in. for the organism. Although we can recognise our susceptible hosts, we currently have limited methods to detect the presence of biofilm and the pathogens.(RESUME D'AUTEUR)
