Norovirus Prevention Guide for Chicago Food Service (2026)

Sanitation Protocols & Hand Hygiene

Norovirus requires rigorous sanitation because it survives on surfaces longer than many pathogens. The Chicago CDPH and FDA mandate that food handlers use soap and warm water (not hand sanitizer alone) for 20 seconds after restroom use, before food handling, and between tasks. Clean and disinfect all high-touch surfaces—door handles, payment terminals, utensils, and cutting boards—every 2 hours using EPA-approved disinfectants effective against norovirus (quaternary ammonium or bleach solutions). Implement separate hand-washing stations for food prep areas and ensure staff understand that norovirus survives alcohol-based sanitizers, making proper handwashing non-negotiable.

Employee Health Screening & Sick Leave Policies

Chicago CDPH guidelines require food facilities to exclude employees showing symptoms of gastrointestinal illness—vomiting, diarrhea, or fever—for at least 24 hours after symptoms stop. Establish a daily health screening checklist that staff complete before shifts, and document all illness-related absences. Train managers to recognize norovirus symptoms and empower employees to report illness without fear of scheduling retaliation. Consider cross-training backup staff so your operation doesn't create pressure to work sick. Notify CDPH if you suspect a norovirus outbreak affecting multiple employees or customers.

Temperature Control & Food Handling

While norovirus is inactivated at high temperatures (above 140°F for 30+ seconds), proper cooking alone isn't sufficient prevention. The FDA Food Code requires that ready-to-eat foods be held at 135°F or above and cold foods at 41°F or below. Use calibrated thermometers to verify temperatures, and monitor raw shellfish storage closely since shellfish are high-risk for norovirus contamination. Prevent cross-contamination by using separate cutting boards and utensils for raw and ready-to-eat foods. Chicago health inspectors verify temperature logs and sanitation records during routine inspections, so maintain detailed documentation of all checks and corrective actions taken.
