A new wave of occupational litigation - Flavor & Fragrance Lawsuits

A new wave of occupational litigation - Flavor & Fragrance Lawsuits


A new wave of flavor and fragrance (Diacetyl) litigation is now emerging against the manufacturers and suppliers of food flavorings for chronic lung disease, bronchiolitis obliterans (BO), and other illnesses, resulting from worker exposures. The litigation results from the insidious return of Diacetyl (2,4-butanedione and biacetyl), as well as 2,3 pentanedione, into foods as artificial flavorings to alter the taste and aroma of products.

Historically, the litigation had its genesis in the manufacturing of microwave popcorn, where exposed to workers suffered lung illness. Most manufacturers removed the product in 2007 as a result of adverse public pressure.

Lack of Regulation
At present, there are no formal regulations to mandate an exposure limit. The National Institute for Occupational Safety and Health [NIOSH] and the American Conference of Governmental Industrial Hygienists [ACGIH] have recommended exposure limits for both Diacetyl and 2,3 pentanedione, not exceeding 1 to 25 ppb.
Diseases Caused by Exposure
Chronic lung diseases
Hypersensitivity pneumonitis
Granulomatous disease

Interstitial lung disease
Eye and skin irritation

Bronchiolitis Obliterans

Chronic shortness of breath with exertion
Night sweats

In 1985 NIOSH investigated the report of two food workers with bronchiolitis obliterans who were employed manufacturing “cannabutter.” In 2000 NIOSH investigated the occupational exposure of 8 microwave popcorn workers in Jasper, Missouri, who suffered from bronchiolitis obliterans. NIOSH published a Health Hazard Evaluation and confirmed the causal relationship between Diacetyl and the medical condition of ill workers, bronchiolitis obliterans.

NIOSH has identified the potential hazard to workers exposed to Diacetyl and its potential causal relation to chronic lung disease, bronchiolitis obliterans, in the following manufacturing facilities:
-Diacetyl manufacturing plants,
-Snack food plants,
-Dairy plants,
-Confection plants, refrigerated job plans,
-Cooking oil use,

-Pet food plants, and coffee roasting plants.

NIOSH and others have reported that exposure to Diacetyl causes not only bronchiolitis obliterans. but other chronic lung diseases, such as hypersensitivity pneumonitis, granulomatous disease, emphysema, asthma, and interstitial lung disease. As a result of the reaction that occurs in the human body, some individuals exposed suffer from eye and skin irritation as a precursor to chronic lung disease.

In New Jersey, it is alleged that some companies that manufacture flavor mixes (e.g., butter flavors) and raw ingredients (e.g., Diacetyl; 2,3 pentanedione) may have workers who are and have been occasionally exposed. Cases are already in litigation on behalf of these workers.
