It stated that “ Diacetyl and 2,3-pentanedione exposures from cigarette smoking far exceed occupational exposures for most food/flavoring workers who smoke. ” Based on this finding, the authors suggested that “ previous claims of a significant exposure – response relationship between diacetyl inhalation and respiratory disease in food/flavoring workers were confounded because none of the investigations considered or quantified the non-occupational diacetyl exposure from cigarette smoke, yet all the cohorts evaluated had considerable smoking …
