A verdict by a Sioux City, Iowa jury awarded $7.5 million for the death of a worker after he developed a rare lung condition, broncholitis obliterans. The worker was a butter flavor mixer with American Popcorn Company.
Ronald Kuiper, who passed away on Wednesday afternoon, was formerly employed at American Popcorn Company as a butter flavor mixer. He had been diagnosed with the rare lung condition called broncholitis obliterans, which has been linked to artificial butter flavor exposure.
The product and chemical is butter flavor containing diacetyl, a chemical which has been found by the National Institute of Safety and Health to cause severe lung injury.
