Sotera Health Holdings LLC has finalized a $408 million settlement for litigation over the company’s use of ethylene oxide (EtO) at a Sterigenics facility in Willowbrook, Ill., although litigation is still pending in connection with sites in other U.S. states. The news comes as med-tech trade associations register their disappointment with an EPA proposed rule for EtO that both the Medical Device Manufacturers Association (MDMA) and the Advanced Medical Technology Association (Advamed) argue would crimp availability of sterilization capacity, which would in turn create shortages of medical devices and supplies that are desperately needed by patients.
