Abstract

Endoscopes are used widely for the diagnosis and therapy of medical disorders. To prevent spread ofnosocomial infection, all endoscopes should undergo thorough cleaning and high-level disinfection following each use. The Food and Drug Administration (FDA) has approved a user-friendly package label for one liquid chemical germicide that requires a 45-minute immersion at 25°C to support a high-level disinfection label claim. Scientific data reviewed here suggest that one can achieve at least an 8-log reduction in M tuberculosis contamination with cleaning (4 logs) followed by chemical disinfection for 20 minutes (4 to 6 logs). The FDA should modify the label to state that if cleaning is accomplished using a standardized cleaning protocol, then a 20-minute immersion at 20°C will be sufficient to achieve high-level disinfection.
