Norovirus in Foodservice: How It Spreads and How to Stop It
Norovirus is one of the leading causes of foodborne illness worldwide — and in the fast‑paced world of foodservice, it can spread like wildfire if not properly controlled. Known for causing sudden outbreaks of vomiting, diarrhea, and stomach cramps, Norovirus is highly contagious and can survive on surfaces for days.
For restaurants, catering companies, and other foodservice operations, understanding how Norovirus spreads is the first step toward preventing it — and protecting both your customers and your reputation.
Person‑to‑Person Transmission
The most common route in foodservice is infected food handlers. Even if symptoms have subsided, individuals can still shed the virus for days.
-
Risk points: Handling ready‑to‑eat foods without gloves, inadequate handwashing after using the restroom, or working while sick.
-
Prevention tip: Enforce strict illness reporting policies and require staff to stay home for at least 48 hours after symptoms end.
Contaminated Surfaces & Utensils
Norovirus can survive on countertops, utensils, and equipment for extended periods.
-
Risk points: Shared prep tools, cutting boards, and high‑touch surfaces like refrigerator handles.
-
Prevention tip: Use EPA‑approved sanitizers effective against Norovirus and clean high‑touch areas frequently throughout the day.
Contaminated Food & Water
Raw produce, shellfish, and ready‑to‑eat foods are common culprits. Contamination can occur at any point — from harvesting to plating.
-
Risk points: Improper washing of fruits and vegetables, using contaminated ice, or sourcing from unsafe suppliers.
-
Prevention tip: Vet suppliers carefully, wash produce thoroughly, and ensure water and ice come from safe, treated sources.
Airborne Particles from Vomiting Events
When someone vomits, tiny droplets containing the virus can land on nearby surfaces or food.
-
Risk points: Dining areas, restrooms, or kitchens where an incident occurs.
-
Prevention tip: Have a vomit and diarrhea cleanup kit on hand and train staff on safe cleanup procedures to avoid cross‑contamination.
