Sterigenics US LLC, of Oak Brook, Ill., has announced it will not reopen its ethylene oxide (EtO) sterilization plant in Willowbrook, Ill., a development that could strain the capacity for sterilization of devices such as duodenoscopes. Illinois is not the only state that is taking action on EtO, however, a predicament that suggests the U.S. federal government may have to insert itself into the discussion in order to avoid a shortage of critical, life-saving devices.
