State and local health officials are investigating an outbreak of a serious infection caused by eating a kind of cantaloupe grown in Colorado that was shipped to Illinois and 16 other states.
The Illinois Department of Health says at least 20 people across the U.S. have become ill after eating cantaloupes contaminated with Listeria monocytogenes bacteria, 2 of whom have died.
There have been reports of possible Listeria cases in Illinois, including some in Cook County, but the health department says none of those have been confirmed.
The confirmed cases have been linked to what are called Rocky Ford cantaloupes shipped by Jensen Farms in Colorado.
The health department is working with the Centers of Disease Control, the U.S. Food and Drug Administration and local health departments in Illinois.
