Transmission ofSalmonella enteritidisafter endoscopic retrograde cholangiopancreatography because of inadequate endoscope decontamination
We report a historic nosocomial outbreak of Salmonella enteritidis affecting 4 inpatients who underwent endoscopic retrograde cholangiopancreatography. The cause was attributed to inadequate decontamination of an on-loan endoscope used over a weekend. This report highlights the risks of using on-loan endoscopes, particularly regarding their commissioning and adherence to disinfection protocols. In an era of increasing antibiotic resistance, transmission of Enterobacteriaceae by endoscopes remains a significant concern.
