WASHINGTON — The Food and Drug Administration is evaluating whether consumers, like workers in popcorn plants, can develop lung disease from inhaling a chemical additive used for butter flavoring in microwave popcorn.

A Denver physician said in a letter to the agency in July that a patient who had eaten several bags of extra butter-flavored popcorn each day for several years had developed symptoms similar to those of some microwave popcorn-plant workers.

The letter “does not present evidence” that consumer exposure to vapors of the chemical diacetyl, generated by microwaving popcorn, causes lung disease, said FDA spokesman Michael Herndon. He said the agency is studying the situation, and “carefully considering the safety and regulatory issues it raises.”

ConAgra Foods Inc., the nation’s largest maker of microwave popcorn including the Orville Redenbacher’s and Act II brands, said it is eliminating “within a year” diacetyl from its microwave popcorn.

“While we are fully confident that microwave popcorn is safe for consumers to prepare and consume, we plan to eliminate the use of added diacetyl in products in order to eliminate even the perception of risks for consumers and to provide our employees who handle large quantities of diacetyl regularly with the safest possible work environment,” said spokeswoman Stephanie Childs.

The industry in 2004 sold more than three billion bags, with sales totaling more than $1 billion, ConAgra said.

In 2000, a physician reported to the Missouri health department that eight workers from a microwave popcorn factory developed lung disease. Studies conducted by the National Institute for Occupational Safety and Health concluded that cumulative exposure to diacetyl vapor over time has the potential to cause serious lung damage and a condition known as bronchiolitis obliterans.

In April, the U.S. Centers for Disease Control and Prevention said workers at factories that make food flavorings as well as popcorn factories are at risk of contracting the hard-to-treat condition.

NIOSH has recommended that manufacturers substitute the chemical with less-dangerous ones, and that workers don masks and other protective gear. Links between the chemical and lung disease have been less clear in consumers, and the FDA has labeled the chemical “generally recognized as safe.” Last year, David Michaels, a professor at the George Washington University School of Public Health and Health Services, petitioned the FDA to drop the designation.

Consumers, not just factory workers, may be in danger from fumes from buttery flavoring in microwave popcorn, according to a warning letter to federal regulators from a doctor at a leading lung research hospital. (more…)

Charlotte’s record-setting heat wave could add another chapter to the history book today, with forecasters expecting temperatures to vault over the 100-degree mark yet again.

And the previously forecast “relief” this weekend might not be such a break, after all.

High temperature records have been set four days this month already, and a fifth mark is possible this afternoon. Yet another record will be threatened Friday.

Forecasters are predicting a high of 101 degrees today in Charlotte, which is near the Aug. 16 record of 102 degrees, set in 1954. Friday’s forecast high is 97, which would equal the record of the day, set in 1911.

A daily record was set Wednesday, with Charlotte’s 99-degree high. That broke the mark of 97, set in 1923.

It’s the same old story for our region.

High pressure is dominating much of the South, pushing temperatures at or above the 100-degree mark. A cold front is forecast to push into the region Friday, and that could set off thunderstorms in the drought-stricken region.

But the cold front won’t do much to cool temperatures.

Forecasters originally thought high temperatures would be pushed back into the upper 80s from Saturday into next week, but they now say the 90s will continue to dominate. Highs could reach the middle 90s Saturday and will be in the lower 90s Sunday.

The only change in the forecast will be welcome — a 30 percent chance of afternoon thunderstorms Saturday, Sunday, Monday and next Wednesday.
