Occupational exposure to diacetyl has been associated with severe respiratory impairment and obliterative bronchiolitis, a serious lung disease that is irreversible. SUMMARY: OSHA is requesting data, information, and comment on issues related to occupational exposure to diacetyl and food flavorings containing diacetyl, including current employee exposures to diacetyl; the relationship between exposure to diacetyl and the development of adverse health effects; exposure assessment and monitoring methods; exposure control methods; employee training; medical surveillance for adverse health effects related to diacetyl exposure; and other pertinent subjects. Several efforts are underway to investigate exposures, improve sampling methods, evaluate engineering controls, use animal toxicology models to study a range of flavorings and determine how lung injury occurs, disseminate important public health information, and determine appropriate steps to help safeguard workers health. In the case of workers at microwave popcorn facilities across the Midwest, NIOSH studies found that mixers who worked with diacetyl and heated soybean oil for more than a year were exposed to higher levels of diacetyl fumes and experienced more shortness of breath than workers employed for less than 12 months or who worked elsewhere in the plant.. Nevertheless, consumers should be aware that some substances are still used in the packaging. As of 2019, the U.S. continues to allow the use of diacetyl in vape products.
