A recent study by Ofstead et al. published in the American Journal of Infection Control described the presence of residual simethicone and non-pathogenic bacterial colonization in endoscopes despite adherence to reprocessing procedures(1). These findings received significant media attention, in part because they were released following a warning issued by the Food and Drug Administration and the Centre for Disease Control regarding the potential transmission of multi-drug resistant bacteria associated with the use of duodenoscopes(2, 3). In light of the findings described by Ofstead et al., the Canadian Association of Gastroenterology (CAG) would like to update its members on what is currently known.
