Bronchiolitis obliterans, a rare, life-threatening lung disease, has been found in eight in eight individuals who worked in California food-flavoring plants between 2003 and 2007. Contracting this disease was apparently the result of inhaling diacetyl, which is also linked to the occurrence of bronchiolitis obliterans in people who work in the microwave popcorn industry.
And the latest issue of Morbidity and Mortality Weekly Report indicates that women who work in battery manufacturing plants have elevated lead levels.
"Bronchiolitis obliterans is a severe lung disease that can be prevented with appropriate measures, such as engineering controls, work practices, medical surveillance, and a respiratory protection program," according to report co-author Dr. Rachael Bailey, an epidemic intelligence service officer at the CDC's National Institute for Occupational Safety and Health.
There are no regulations governing U.S. food flavoring plants.
