Hospital portable water can harbor nontuberculous Mycobacterium species (e.g., M. mucogenicum, M. rhodesiae, M. peregrinum, M. fortuitum, M. porcinum) and represents a potential source for HAIs.[25,26] Although rare, one study reported that a 5-year outbreak of community-acquired and hospital-acquired M. porcinum infections was linked to contamination of the public water supply.[27] Nontuberculous mycobacterium contamination of drinking water can serve as a long-term reservoir for patient colonization (especially sputum) and clinical disease.[27] Pseudo-outbreaks of nontuberculous Mycobacterium species can occur in hospitals from laboratory contamination as well as contamination of ice machines.[28,29] Evaluating laboratory water sources and ice machines in healthcare facilities is also important after a flood to prevent this from occurring.
