A southwest suburban woman who was authorized by the Illinois Department of Public Health to teach food service sanitation classes and administer state certification exams was convicted of conspiracy to commit bribery for accepting at least $79,650 in return for fraudulently arranging to provide bogus certificates for at least 531 individuals. The defendant, Maryanne Koll, a retired Chicago Public Health Department food sanitation inspector who operated Kollmar Food Safety Institute from her home in Burr Ridge, was convicted of one count of bribery conspiracy in a written ruling that was made public Friday by a federal judge following a stipulated bench trial.
