Is there an ethylene oxide class action lawsuit?

Examples of lawsuits that may develop into class action

Victims of EtO emissions have filed group cases and class-action-style lawsuits against companies and facilities across the country, particularly since 2000, and many have successfully reached settlements, with some reaching hundreds of millions of dollars in compensation.

• Sterigenics U.S., LLC, in California - Sterigenics has faced hundreds of lawsuits from affected workers and residents, alleging that their cancer was associated with ethylene oxide exposure. In 2025 alone, the ongoing legal action against Sterigenics led to 97 lawsuit settlements with payments of 13$ million to plaintiffs.
• Terumo BCT Sterilization Service, Inc. in Colorado - Terumo was sued in 2022 and 2023 by two dozen victims who claimed compensation for toxic exposure in Colorado.
• B. Braun Med Inc. in Pennsylvania - After developing a range of cancers, including leukemia, several people in Allentown, Pennsylvania, successfully filed toxic exposure claims.

Some cases may be certified, or are moving toward certification as class-action lawsuits, but often, the litigation is still in earlier stages (proposed class, multi-plaintiff, etc). The classification also depends on the state.
