New York Woman Files Suit Charging Butter Flavoring Chemical Diacetyl, Used in Microwave Popcorn, Led to Serious Lung Injury

May 1, 2010

April 30, 2010, Queens County, NY – Wendy R. Fleishmann and Elizabeth Alexander of the national plaintiffs' law firm Lieff Cabraser Heimann & Bernstein, LLP, and Ken McClain of the Kansas City, Missouri law firm, Humphrey Farrington and McClain, P.C., announced today that Agnes Mercado, of Queens County, New York, filed a personal injury lawsuit against ConAgra Foods, Inc., Givaudan Flavors Corp. and numerous diacetyl manufacturers.

In April, 2010 Ms. Mercado was diagnosed with a severe lung disease as a result of her exposure to ConAgra's microwave popcorn which contained butter flavorings with added diacetyl. The disease is associated with inhaling butter flavoring vapors and has been identified as bronchiolitis obliterans -- literally, an obliteration of the lung's airways. Breathing tests can identify difficulty in moving air in and out of the lungs, called lung obstruction. In the case of bronchiolitis obliterans, that obstruction is "fixed," meaning it doesn't respond to normal asthma medications.

About her injury, Ms. Mercado stated, "I have always taken good care of myself and never would have thought that something as seemingly harmless as eating microwave popcorn would have hurt me so badly."

The lawsuit charges that Ms. Mercado sustained a severe lung disease after consuming microwave popcorn containing the butter flavoring chemical diacetyl. The chemical is used for the aroma and taste in butter, some cheeses and snack and bakery products.

Wendy Fleishman stated, "The product diacetyl has destroyed our client's health. It should never have been added to microwave popcorn or any other food." Ken McClain stated, "Unfortunately, my firm represents consumers who have been diagnosed with bronchiolitis obliterans. The hazards were unknown by consumers for far too long."

The complaint further alleges that exposure to butter flavoring containing added diacetyl may cause other health problems including asthma, bronchiectasis, chronic obstructed bronchitis, pulmonary disease, emphysema, lung impairment as well as several others.
