Maria, who worked at Cardinal Health's warehouse in El Paso, was diagnosed with stage 3 triple-negative breast cancer nearly a decade after her employment. She learned about ethylene oxide, a toxic chemical used for sterilizing medical devices, and its potential link to her cancer. Ethylene oxide is classified as a carcinogen by the EPA, with studies indicating it can increase cancer risks, particularly for breast and lung cancers. Investigations suggest that emissions from Cardinal's warehouses may expose local residents to cancer risks above acceptable levels. While new regulations have been introduced to control emissions, they do not cover all aspects of the medical supply chain, leaving many workers and nearby communities vulnerable. Maria's case highlights the urgent need for stricter safety measures and accountability in the industry.
