Norovirus Prevention Guide for Las Vegas Food Service

Employee Health Screening & Exclusion Protocols

The Southern Nevada Health District requires food handlers showing symptoms of norovirus—vomiting, diarrhea, or gastroenteritis—to be immediately excluded from work. Establish a daily health check-in system where staff report symptoms before shifts; many Las Vegas operators use digital forms or text check-ins to document compliance. Employees who have worked while ill must be reported to the health district, and cross-contamination to other staff must be investigated. Train managers to recognize norovirus symptoms and enforce the 24-48 hour exclusion period after symptoms resolve, per FDA Food Code guidelines adopted by Nevada regulations. Document all health screening records for at least 90 days to demonstrate due diligence during inspections.

Enhanced Sanitation & Surface Decontamination

Norovirus survives on hard surfaces for hours, requiring EPA-approved disinfectants and bleach solutions (typically 1,000-5,000 ppm) for contaminated areas. Las Vegas food service operations must implement hourly sanitization of high-touch zones: door handles, POS terminals, ice bins, and beverage stations. The Southern Nevada Health District enforces California's norovirus guidance, which mandates immediate closure and deep cleaning of affected food prep areas if contamination is suspected. Use separate color-coded cleaning supplies for restrooms (highest contamination risk) and food contact surfaces to prevent cross-contamination. Document all sanitization activities with timestamps and staff initials, maintaining records for health department review during routine inspections or outbreak investigations.

Food Handling Controls & Temperature Management

While norovirus cannot be eliminated by cooking (unlike bacteria), proper food handling prevents raw product contamination. Ready-to-eat foods must never be handled by staff with symptoms or exposed employees during outbreak windows. The FDA Food Code emphasizes proper handwashing for 20 seconds with soap and warm water after restroom use—alcohol-based sanitizers alone are ineffective against norovirus. Las Vegas restaurants must maintain separate, dedicated handwashing stations in all food prep and restroom areas, monitored for soap and paper towel availability. Implement cold chain management: monitor food storage temperatures (41°F or below) with calibrated thermometers, as temperature abuse increases cross-contamination risks when combined with poor sanitation practices.
