Hepatitis A Prevention for Chicago Food Service

Chicago's Hepatitis A Regulatory Framework

The Chicago Department of Public Health enforces regulations under the Illinois Food Safety Act and local municipal codes requiring food establishments to maintain hepatitis A prevention protocols. All food handlers in Chicago must complete food safety certification through an approved provider, with emphasis on proper handwashing and hygiene during high-risk meal preparation. CDPH conducts routine inspections of food service facilities and can issue citations for violations related to handwashing stations, temperature control, and cross-contamination prevention. Establishments must maintain documentation of employee health policies and report suspected hepatitis A cases to CDPH within 24 hours of diagnosis.

Common Hepatitis A Sources in Food Service

Hepatitis A transmission in food service primarily occurs through infected food handlers who prepare ready-to-eat foods without proper handwashing, particularly after restroom use. Contaminated produce—especially leafy greens, berries, and shellfish from polluted waters—poses significant risk and requires careful sourcing verification. The virus survives on surfaces and hands for hours, making it critical to use hot water and soap for at least 20 seconds when washing hands, especially between tasks. Chicago establishments must verify supplier compliance with FDA and state produce safety standards and maintain records of shellfish origin through the Interstate Shellfish Sanitation Program.

Prevention Protocols and Illinois Reporting Requirements

Effective hepatitis A prevention requires designated handwashing stations with hot water, soap, and single-use towels in all food prep areas, bathrooms, and break rooms—standards enforced during CDPH inspections. All food handlers showing symptoms of jaundice, abdominal pain, or diarrhea must be immediately removed from duty and referred for medical evaluation; establishments cannot return employees without written medical clearance. Illinois Department of Public Health (IDPH) requires facilities to report confirmed or suspected hepatitis A cases within one business day to the local health department, which then initiates contact tracing and may issue public health directives. Food establishments must cooperate with outbreak investigations, provide employee records, and implement enhanced cleaning protocols using EPA-approved disinfectants on high-touch surfaces during active cases.
