Pluralibacter gergoviae is a rare opportunistic gram-negative Bacillus in humans and exhibits resistance to preservatives in cosmetic products. In this case report, we present nosocomial P. gergoviae sepsis that developed through contamination from a cleaning product in a previously healthy child without known chronic diseases, during pediatric intensive care unit care. Contamination with the same microorganism was detected even in unused samples of the cleaning product, leading to a recall of these items. This report highlights the case of hospital-acquired P. gergoviae sepsis to emphasize the importance of adherence to antiseptic protocols by health care workers, as well as the necessity for medical materials used in treatment and patient care to be produced and stored in compliance with appropriate regulations.
