Ozone Service Kills Norovirus in Restaurant Kitchens, Hotels, and Cruise Ships — WHD
A 4-star, 80-seat Bangkok restaurant: late April 2026, 23 customers fell ill with severe gastroenteritis after eating the same meal. Lab tests confirmed Norovirus contamination on the cotton-candy dessert. The Department of Health ordered a 7-day closure. Half the customer base disappeared. Norovirus outbreaks plague restaurants, hotels, and cruise ships every year. Ozone kills Norovirus at 99.99% within 30-60 minutes. WHD is Thailand's only Hospital-Grade ozone service operator with 10,000 mg/h generators.
Norovirus — How Dangerous
Norovirus is the "king of gastroenteritis" — infectious dose only 18 viral particles. Symptoms: severe diarrhea, vomiting, abdominal pain, dehydration. In elderly, infants, and cancer patients, dehydration can be fatal.
Survives on surfaces 2 weeks. Heat-resistant to 60°C. Resists common disinfectants (alcohol does NOT kill Norovirus). Spreads through kitchens, bathrooms, food-contact surfaces.
US FDA reports Norovirus causes 58% of global food poisoning. In Thailand, restaurant and high-end hotel outbreaks are underdetected.
Why Conventional Methods Fail
70% alcohol does NOT kill Norovirus (FDA confirmed). Requires 1,000 ppm chlorine or high-level oxidizers. Common QAC disinfectants fail.
Sterilization-grade ozone is the only solution that kills Norovirus in spaces sprays cannot reach — under stoves, under prep tables, inside freezers, staff bathrooms, AC systems.
