EPA Weakens Cancer Chemical Rules for Medical Sterilizers

The Environmental Protection Agency (EPA) has proposed weakening air pollution limits for ethylene oxide, a chemical crucial for sterilizing medical equipment such as catheters and syringes. This proposed rule aims to reverse previous Biden-administration findings that identified significant cancer risks at facilities using this chemical. The EPA stated its concern that existing standards could jeopardize the sterilization of life-saving medical devices and threaten the domestic supply chain for essential equipment.

Ethylene oxide is known to cause leukemia and other cancers with long-term exposure, affecting workers and nearby residents. Environmental advocates, including the American Lung Association, have condemned the proposal, emphasizing the documented health dangers and elevated cancer risks for communities located near sterilization plants. Many of these facilities are situated in minority communities, leading to disproportionate exposure.

This proposed change follows a pattern of the EPA under the Trump administration relaxing pollution controls for industries. A 2024 EPA rule had aimed to drastically reduce ethylene oxide emissions by approximately 90% at nearly 90 commercial sterilization facilities nationwide. The earlier regulation also mandated air testing for the chemical and ensured pollution controls were functional.
