The state public health department has linked some illegally manufactured cheese with 100 cases of salmonella. Thirteen counties have reported salmonella cases that have the same strain that was found in illegally produced Mexican-style cheese. Many of those affected say they bought the cheese from worksites, street vendors or from relatives or friends.
Marion and Washington Counties in southern Illinois are included in the list, with the rest in central and upstate Illinois. The questionable cheese is usually not labeled and often comes wrapped in aluminum foil. A third of all of the cases of salmonella in this outbreak have resulted in hospitalization.
