Top 10 Foggers and Disinfectants for Hotels Hosting Conferences and Seminars: Lessons from About 60 NAACP Convention Attendees Fall Ill With Norovirus After Hotel Banquet in Redwood City (2014)
Food Safety News reported about 60 NAACP California Hawaii convention attendees with nausea and vomiting after the closing banquet at the Sofitel in Redwood City; norovirus was confirmed and the hotel stopped food service and sanitised the property. What should Thai conference hotels prepare?
The Real Story from the News: A Closing Banquet That Ended in Illness
Food Safety News reported on 8 November 2014 that about 60 attendees fell ill hours after the closing banquet on 26 October 2014.
San Mateo County Health confirmed norovirus, and the hotel stopped serving food during the investigation and sanitised the property.
Why Choosing the Right Equipment Matters
Thai conference hotels host hundreds of attendees sharing meeting rooms, toilets and buffets for days. Screening sick kitchen staff, soap handwashing, buffet management and cleaning meeting rooms and toilets with norovirus-labelled products reduce risk.

Prefer Not to Do It Yourself? Use a Professional Service
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Frequently Asked Questions
Q: What to do after norovirus at a conference? A: Stop serving implicated food, notify authorities and clean the whole venue with norovirus-labelled products.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Health References
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
Summary
Redwood City shows large conferences need hygiene systems. Prepared hotels keep their corporate clients.
