State health officials say they have traced a widespread salmonella outbreak at some Chicago-area Subway restaurants to a food distributor based in central Illinois. The outbreak led to 109 confirmed salmonella cases and some 90 probable or suspected cases between late April and June.

Investigators believe the most likely source of the lettuce, tomatoes and olives linked to the illness was Sysco in Lincoln, Illinois, which delivered produce to the affected subway restaurants.
