Résumé |
In-refrigerator water dispensing systems are ubiquitous in residential homes with tap water as the inflow. Passage through these systems resulted in significant microbial growth in the water, with the abundance of potential opportunistic pathogens Mycobacterium and Pseudomonas increasing by 8,053- and 221-fold, respectively. Elevated exposure to microbial contaminants linked to in-refrigerator water dispensing systems may represent a significant public health concern.

• | In-refrigerator water dispensing systems are widely used in residential homes. |
• | Significant increases in microbial contamination were detected in these systems. |
• | Increased microbial contamination was linked to the loss of disinfectant residual. |
• | In-refrigerator water dispensing systems may serve as sources of pathogen exposure. |
