The True Story: Cooking Chickens That Had Died

On 14 February 2026, Cambodia's Ministry of Health announced the country's first human H5N1 case of 2026, a 30-year-old man in Meanrith village, Tuek Chhou district, Kampot province, in the south-west.

Officials said dead chickens were found at his house and had been cooked three days before he fell ill. He had fever, cough and abdominal pain, recovered after intensive care and went home, and close contacts received Tamiflu.

The Key Lesson: Unsafe Poultry Handling Happens in Everyday Life

Thai fresh markets and poultry stalls butcher and handle poultry every day. Points to watch are:

• Sick or dead birds that may be sold
• Chopping boards and knives used all day
• Stall floors and drains wet with blood
• Vendors' hands switching between cash and meat
• Market aisles shoppers walk all day

How Flu Spreads

According to the World Health Organization, seasonal influenza spreads easily where people gather, such as schools and nursing homes. It spreads through droplets when people cough or sneeze, and through hands that touch contaminated surfaces and then the eyes, nose or mouth. Most people recover within a week, but young children, older adults, pregnant women and people with chronic illness are at risk of severe disease. Influenza is an enveloped virus, which suitable disinfectants can inactivate.

Risk Register for Fresh Markets and Poultry Stalls

1. Poultry from unknown sources: likelihood medium / impact high / level high. Mitigation: buy only from certified sources. Owner: poultry vendor
2. Vendors butcher without gloves: likelihood high / impact medium / level high. Mitigation: gloves and aprons every time. Owner: poultry vendor
3. Boards and knives not cleaned during the day: likelihood high / impact medium / level high. Mitigation: wash with detergent and air-dry several times a day. Owner: poultry vendor
4. Dirty stall floors and drains: likelihood high / impact medium / level high. Mitigation: wash floors daily and fog the market on a schedule. Owner: market management
5. Vendors handle cash then meat: likelihood medium / impact low / level low. Mitigation: separate cashier or QR payment. Owner: poultry vendor

Ways to Reduce Bird Flu Risk in Fresh Markets

1. Source poultry from certified suppliers
2. Never sell or eat sick or dead birds under any circumstances
3. Wear gloves and aprons every time
4. Wash boards and knives several times a day
5. Wash stall floors and drains daily
6. Take QR payment to reduce cash handling
7. Fog the market on a schedule after closing

How ULV Disinfection Fogging Helps

The World Health Disinfection disinfection service uses ULV fogging machines that turn the disinfectant into a fine mist. It settles across the whole area, including corners, curtains, upholstery and surfaces that hand wiping cannot reach.

• Whole-area coverage without relying on wiping spot by spot
• Quick return to use, typically about 30 minutes after fogging
• Uses Chemgene HLD4H, which meets EN 14476 for virucidal activity according to the product page
• The team wears full protective equipment, so owners and staff do not take the risk themselves
• Report and photos after the job for customers, management or authorities
• Tax invoice with 3% withholding tax for companies and agencies

Ozone Treatment for Closed Rooms and Stuffy Spaces

The World Health Disinfection ozone treatment service uses machines that generate ozone gas from oxygen in the air. It suits closed rooms such as meeting rooms, bedrooms, classrooms, sick bays and vans, helping reduce germs in the air and on surfaces and removing stale odours. Ozone breaks back down into oxygen after treatment, leaving no residue.

• Works alongside disinfection fogging: spray or wipe surfaces first, then use ozone for the air and corners of closed rooms
• No people or pets in the room during treatment: the team seals the room and runs a timer
• Ventilate after treatment before normal use resumes
• Machines tested by Intertek, according to WHD's service page
• Ideal after someone has been ill, such as recovered patients' rooms, shared bedrooms and shuttle vans
