In this episode, Ayesha talked about new rules that the US Environmental Protection Agency (EPA is proposing for curbing ethylene oxide emissions from sterilization facilities. The agency says the new guidelines would help reduce emissions by 80 percent, which is particularly important for communities that live near sterilization plants and workers who work at them. Ethylene oxide is a known carcinogenic, with long-term exposure to the odorless, colorless gas being associated with cancers including breast cancer and myeloma among others. The gas is used to sterilize medical equipment as well as spices. Hear about the new proposed rules and industry reactions to them.
