This chemical has been used as a marker of exposure to flavoring vapors in investigations evaluating lung disease in microwave popcorn manufacturing facilities.1 Acetoin (also called acetyl methyl carbinol), 2,3-pentanedione, 2,3-hexanedione and 2,3-heptanedione are all structurally related to diacetyl and have been suggested as possible substitutes for diacetyl. Responding to allegations about coffee farms in Guatemala, William "Bill" Murray, President and CEO of the National Coffee Association, commented: NCA and our member companies agree that child labor has no place in the coffee supply chain. As part of the partnership, NCA President &CEO William (Bill) Murray joins the Sustainable Coffee Challenge Advisory Council, where he will leverage the technical, operational, and consumer expertise of NCAs vast membership to help inform the Challenges strategy and support specific programs. Unlike workers, so far there have not been peer-reviewed scientific studies showing that consumers using products such as microwave popcorn that contain butter flavoring chemicals are at increased risk for lung disease. Despite varying opinions about this potential hazard, there are a number of exposure guidelines and recommended precautions that have been suggested by various authorities (described in the NCA members-exclusiveFAQbelow).

As noted in the NIOSH Alert, Preventing Lung Disease in Workers Who Use or Make Flavorings, the flavorings industry has estimated that over a thousand flavoring ingredients have the potential to be respiratory hazards due to possible volatility and irritant properties (alpha, beta-unsaturated aldehydes and ketones, aliphatic aldehydes, aliphatic carboxylic acids, aliphatic amines, and aliphatic aromatic thiols and sulfides). font-size: .75em;
Proposition 65 warnings now greet guests at Disneyland, drivers at California parking garages, visitors at hotels, shoppers at car dealerships and lunchgoers in fast-food lines.
