Researchers at the University of Nebraska Medical Center will study the prevention and treatment of lung disease in workers at hog farms.

The school has received $3.5 million in grants from the National Institute of Occupational Safety and Health and the National Institutes of Health to fund the five-year study.

UNMC says workers at hog farms and other animal facilities are at risk for lung disease because of dust exposure, with about a third developing bronchitis, asthma or something more severe.

The research will be the first to look at how the body's immune system responds to organic dust.

Iowa’s Center for Agricultural Safety and Health provides information on the proper use of respirators on swine farms.
