Diacetyl Exposure

Diacetyl is a chemical used to create a buttery flavor in foods and is produced during the fermentation of beer. While it is generally safe in small amounts, prolonged exposure to high levels of diacetyl, especially in workplaces like popcorn factories or breweries, can pose health risks. It has been linked to a serious lung condition known as "popcorn lung" or bronchiolitis obliterans, which causes coughing and breathing difficulties. To minimize risk, proper ventilation and protective measures are important in environments with potential diacetyl exposure.
