In 2024, the EPA issued a ruling that aims to reduce ethylene oxide emissions by 90%. Despite this, workers and residents who lived near EtO-emitting facilities are still facing elevated cancer risks. There are hundreds of commercial facilities in the U.S. that have been emitting ethylene oxide (EtO) gas for years.
In the earlier decades after EtO sterilization was patented, these companies emitted tons of EtO gas with little to no oversight, exposing the facility workers and residents in nearby communities. In 2024, the Environmental Protection Agency finally issued a ruling requiring around 90 facilities nationwide to reduce their EtO emissions by 90%. This ruling is an important step in acknowledging the danger of EtO exposure to humans.
Ethylene oxide is a potent carcinogen that sterilization facilities usually emit as a colorless gas. This compound is an effective sterilizer because it can damage microorganisms' DNA, but the same property makes it dangerous to humans exposed to it. A person can be exposed to EtO gas for decades and not realize it, not knowing that exposure may have already increased their risk of developing cancer. The latency period for EtO-related cancer varies depending on the type of cancer, ranging from 9 to 20 years after exposure.
While the EPA ruling may help reduce cancer risk for future workers and residents, those who have already been exposed to EtO for decades are still facing the consequences of nearly 50 years of EtO sterilization.
Industry groups that use EtO continue to fight back against EPA policies, which means it may be difficult to pursue compensation claims against these companies. The 2024 EPA ruling does not automatically grant compensation to victims of EtO exposure, but it can be a useful tool in supporting an ethylene oxide claim. It is a formal acknowledgement of the harmful effects of EtO on public health, and it can serve as a basis for determining how unsafe your working or living conditions were.
