Ethylene oxide (EtO) is a highly toxic chemical used to sterilize medical equipment and manufacture other chemicals. The EPA determined in 2016 that EtO is carcinogenic to humans at exposure levels far lower than previously thought. Residents living near EtO-emitting facilities in Georgia, Illinois, Texas, Colorado, and other states have filed lawsuits alleging their cancers — including lymphoma, breast cancer, and leukemia — were caused by chronic exposure to EtO emissions.
