Sotera Health Services LLC, the parent company of Sterigenics US LLC, has agreed to pay $408 million to settle more than 870 lawsuits pending against the company in Illinois as a means of moving past the specter of ongoing litigation over Sterigenics’ use of ethylene oxide (EtO) for contract medical device sterilization. The settlement may open the doors to litigation over other sterilization plants’ use of the sterilant, constituting an industry-wide attack on device sterilization services that may crimp supplies of devices that are not candidates for other methods of sterilization.
