The Environmental Health Division enforces food protection by investigating food-borne illnesses and other complaints after a problem has occurred. To report a food-borne illness, please see our "Make a Complaint" page. To file a complaint, you may either call the department at 309-679-6161 or email us. This is the next step in protection after prevention.
