Huntington Memorial Hospital in Pasadena announced in late August they are investigating the possibility of patients being infected with pseudomonas bacteria due to contaminated duodenoscopes made by Olympus. The hospital has been contacting those patients who might have been exposed to this superbug during an ERCP procedure (a fiber optic scope used to diagnose and treat conditions of the gastrointestinal tract and gall bladder).

Earlier this year there were similar superbug outbreaks at UCLA and Cedars-Sinai hospitals. Olympus has been criticized by the FDA for their failure to have standard procedures to promptly report serious problems related to its devices.
