Death by Popcorn

Published 14 September 07 02:43 PM | NextStudent

Microwave popcorn “pushers” grossed well over a billion dollars ($1.33 billion to be exact) in the year 2000.

But this popular, ubiquitous snack food may be adversely affecting your health, making you sick and potentially even leading to death.

We’re totally serious: Your microwave popcorn could be killing you.

Smog, Carbon Monoxide, and Now—the Waft of Bogus Butter

Whether you’re settling in on the couch to take a TiVo break or just looking for an easy snack, microwave popcorn has a tantalizing go-to convenience: five minutes and you’re in hot buttered heaven.

But that rich, savory smell is exactly what got one Colorado man seriously sick. “When he broke open the bags, after the steam came out, he would often inhale the fragrance because he liked it so much,” writes Gardiner Harris in a New York Times article (“Doctor Links a Man’s Illness to a Microwave Popcorn Habit,” Sep. 5, 2007).

That fragrance comes from diacetyl, a chemical added to microwave popcorn to give it its buttery flavor and smell. Although eating foods that contain diacetyl hasn’t previously been found to pose health risks, inhalation of the fumes produced when diacetyl is heated has been linked to “popcorn lung,” a respiratory disease found in workers at food-flavoring factories and popcorn plants.

The Colorado man, Wayne Watson, went to his doctor, plagued by a worsening cough and deteriorating shortness of breath.

A self-confessed “Mr. Popcorn,” Watson told his personal physician, Dr. Cecile Rose, that he had been eating at least two bags of microwave popcorn every day for over 10 years. Rose discovered the popcorn link on a hunch, asking Watson about his popcorn consumption after noticing similarities between Watson’s symptoms and those of popcorn factory workers afflicted with popcorn lung.

Following her theory, Rose measured levels of diacetyl in Watson’s home after he made popcorn and found levels of the chemical were comparable to those in microwave popcorn plants. Naturally, she encouraged Watson to kick his popcorn habit.

Six months later, Watson’s lung condition has improved. But that hasn’t alleviated concerns among the medical community and industry officials: Until Watson, popcorn lung had only been found only in flood-flavoring and popcorn plant workers, not in everyday consumers.

Professional Poppers Plagued by “Popcorn Lung”

Popcorn lung, medically referred to as bronchiolitis obliterans, is the obliteration of tiny airways in the lungs and can be fatal. When the vapors from heated diacetyl are inhaled over a long period of time, Harris explains, “the small airways in the lungs [can] become swollen and scarred. Sufferers can breathe in deeply, but they have difficulty exhaling.”

Flavoring manufacturers have so far paid out over $100 million as a result of lawsuits brought by affected workers, according to ABC News (“Could Microwave Popcorn Be Toxic?,” May 16, 2007).

ABC recounts the case of Jerry Blaylock, a 53-year-old employee for a flavoring company in St. Louis, Mo. After just 10 months at the plant, Blaylock developed the condition and his lungs now only function at 45 percent capacity. Blaylock says he can no longer take his grandchildren to amusement parks or the zoo.

ConAgra Foods, manufacturer of Orville Redenbacher popcorn, has acknowledged a concern for “workplace exposure” to diacetyl, but told ABC News that “everyday use of its popcorn was safe for consumers.”

Despite ConAgra’s and other manufacturers’ assurances that the disease is isolated to plant workers, Watson’s case—which, according to Daniel DeNoon at WebMD, led Rose to fire off a letter on July 18 to the Food and Drug Administration, the Centers for Disease Control and Prevention, the Environmental Protection Agency, and the Occupational Safety and Health Administration—has raised concerns about the risks to consumers (“Microwave Popcorn Linked to Lung Harm,” Sep. 5, 2007).

Stopping the Pop, at Least for Now

So what does this mean for those of us who love our microwave popcorn and refuse to part with it, in spite of all the evidence that those delicious buttery aromas could be harming us?

You could continue eating it, but with some precautions. Here are some suggestions for dealing with the deadly fumes when your bag is fresh from the microwave:

§ Open it underneath your stove’s fan in the kitchen while holding your breath.

§ Have your least favorite roommate open it for you, then pretend you never read this article.

§ Open the bag and eat as much as you can as quickly as possible without breathing. Hope you don’t burn yourself.
