EPA believes more needs to be done to protect people from EtO
In November, EPA released its draft risk assessment on the pesticide Ethylene Oxide (EtO). The agency says it believes additional steps will be necessary to lessen the risks associated with the use of EtO.
EtO is a substance used to sterilize medical equipment and spices — both things that can be difficult or impossible to sterilize using different means. EtO is used on 50 percent of all sterilized medical devices in the U.S. annually. It is used on approximately 30 percent of all spices in the U.S.
The substance is up for its 15-year registration review under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). As part of the registration review, the agency is continuing to assess potential human health risks that come from working in facilities that fumigate with EtO, living in communities near EtO facilities, and consuming spices treated with EtO.
The draft risk assessment for the registration review looks at a wide range of possible levels of EtO that could affect a person’s long-term risks of getting cancer from chronic exposures to EtO, either in the workplace or through the outdoor air. Based on all available information about EtO’s toxicity, EPA found that inhaling EtO over many decades can cause cancer risks of concern. Therefore, more must be done to protect the health of workers and surrounding communities.
The next step will be to issue a proposed interim decision, which is used to outline the potential risk management options to address any potential risks of concern.
In addition, EPA is working to reduce EtO emissions to the outdoor air by reviewing Clear Air Act rules for industries that emit EtO. The agency EPA is also evaluating new technologies and methods for measuring the chemical.
