CHICAGO — Officials say 11 people were taken to Chicago hospitals after a reported leak of carbon dioxide and carbon monoxide at a meatpacking plant.
Emergency crews were called Monday to the Battaglia Foodservice Distributors plant in an industrial area in the city's Lower West Side district.
Chicago Fire Department spokesman Larry Merritt says about 25 workers were in the plant at the time. He says those taken to hospitals had non-life-threatening injuries.
Merritt says the leak came from machinery at the plant and was believed to have been caused by human error. No surrounding businesses were evacuated. Firefighters used fans to ventilate the building.
