Title: Occupational Exposure to Diacetyl and Food Flavorings Containing Diacetyl 

Abstract: On July 26, 2006, the United Food and Commercial Workers International Union (UFCW) and the International Brotherhood of Teamsters (IBT) petitioned DOL for an Emergency Temporary Standard (ETS) for all employees exposed to diacetyl, a major component in artificial butter flavoring. Diacetyl and a number of other volatile organic compounds are used to manufacture artificial butter food flavorings. These food flavorings are used by various food manufacturers in a multitude of food products including microwave popcorn, certain bakery goods, and some snack foods. OSHA denied the petition on September 25, 2007, but has initiated 6(b) rulemaking. Evidence from NIOSH and other sources indicated that employee exposure to diacetyl and food flavorings containing diacetyl is associated with bronchiolitis obliterans, a debilitating and potentially fatal disease of the small airways in the lung. Severe obstructive airway disease has been observed in the microwave popcorn industry and in food flavoring manufacturing plants. Experimental evidence has shown that inhalation exposure to artificial butter flavoring vapors and diacetyl damaged tissue lining, the nose, and airways of rats and mice. OSHA published an Advanced Notice of Proposed Rulemaking (ANPRM) on January 21, 2009, but withdrew the ANPRM on March 17, 2009, in order to facilitate timely development of a standard. The Agency subsequently initiated review of the draft proposed standard in accordance with the Small Business Regulatory Enforcement Fairness Act (SBREFA). The SBREFA Panel Report was completed on July 2, 2009.
