Norovirus Prevention Guide for Houston Food Service

Employee Health Screening & Exclusion Protocols

The Texas Food Establishment Rules (Chapter 228) mandate that food employees reporting vomiting, diarrhea, or jaundice must be excluded from food handling duties immediately. Houston food operations should implement daily health check-ins before shifts, asking staff directly about gastrointestinal symptoms. Employees who worked while symptomatic must be documented and reported to the Houston Health Department within 24 hours if a confirmed norovirus exposure is suspected. Establish a clear sick leave policy that doesn't penalize workers for reporting illness—this encourages compliance. Consider cross-training kitchen staff to maintain operations when key employees are unavailable due to illness.

Sanitation & Environmental Controls for Norovirus

Norovirus survives on surfaces for hours to days and spreads rapidly through contaminated food contact surfaces and restrooms. The FDA Food Code recommends using a sanitizer solution of 1,000–5,000 ppm of sodium hypochlorite (bleach) or equivalent EPA-approved disinfectant specifically labeled for norovirus. Clean and sanitize all food contact surfaces, door handles, restroom fixtures, and POS terminals at minimum every 4 hours, and immediately after any known contamination. Houston food service staff must wash hands for 20 seconds with soap and warm water—hand sanitizer alone is insufficient against norovirus. When norovirus contamination is confirmed, conduct a deep sanitation using a commercial-grade EPA-registered disinfectant, and document all steps for health department compliance.

Temperature Monitoring & Safe Food Handling

Norovirus can contaminate ready-to-eat foods during preparation by infected employees, even if the food is cooked (norovirus is typically transmitted by infected food handlers, not through cooking failure). Texas rules require all potentially hazardous foods to be held at proper temperatures: hot foods at 135°F or above, cold foods at 41°F or below. Implement temperature logs using calibrated thermometers and document readings at opening, mid-shift, and closing. Train all staff on the critical importance of handwashing after restroom use and between tasks; assign a manager to verify compliance during service. Houston Health Department inspectors evaluate food safety practices under Texas Administrative Code Title 25, Part 1, so maintaining detailed temperature and sanitation records protects your business during inspections.
