The Sterigenics Willowbrook Case
After updated EPA data showed significantly elevated cancer risk from Sterigenics' Willowbrook, Illinois facility, thousands of residents sued. In 2023, Sterigenics settled approximately $408 million -- the largest environmental mass tort settlement in Illinois history. The settlement resolved claims from residents who lived or worked near the facility during its operating period.
Expanding Litigation at Other Sites
EPA mapping of EtO emissions has identified numerous sites nationally with elevated cancer risk. New class actions are being filed against facility operators including Becton Dickinson and Medline. The Sterigenics settlement establishes a framework for valuing individual cases at other sites.
Who Qualifies
Residents who lived or worked near an EtO sterilization facility and developed cancer -- particularly breast cancer, non-Hodgkin lymphoma, or leukemia -- may have viable claims. Proximity and duration of residence are key factors.
Status 2026
The Sterigenics Illinois settlement has been administered. Litigation at other EtO facilities is in various stages. This is an active and expanding mass tort area.
