The 2026 (B.E. 2569) Krasae Bon, Klaeng Flood: What Was Reported

According to 4Force News on 29 September 2026, water from the Prasae Reservoir overflowed the spillway and surged into Moo 4, Krasae Bon subdistrict, Klaeng district, Rayong, affecting several hundred households and durian orchards. Residents of sixty years said they had never experienced anything like it. Rescue teams evacuated elderly residents and laid sandbags, and as of 03:15 on 28 September the water had not yet receded.

These details reflect the date of the report. Conditions change daily, so follow announcements from Klaeng district, Rayong province and the reservoir authorities.

Nationally, the Department of Disaster Prevention and Mitigation (DDPM) reported, as of 06:00 on 7 October 2026, that 27 provinces plus Bangkok were affected, covering 123 districts, 984 subdistricts and 1,154,875 households, with more than 3.1 million people affected.

Krasae Bon is orchard country. Many homes are single-storey or raised houses with a ground-floor kitchen, often a separate Thai kitchen at the back with a wooden food cupboard, water jars, a rice bin and a fridge standing on the floor. When water arrives suddenly, food and kitchenware are usually the first things submerged.

A Typical Scenario: The Back Kitchen That Would Not Stop Smelling Sour

Example case written to illustrate a common post-flood situation. It is not an interview with any resident of Krasae Bon.

Auntie Juk lives with two grandchildren in a raised wooden house in Klaeng. The kitchen sits downstairs at the back, with a wooden food cupboard, a rice bin, an old fridge and a rack of eggs from her backyard hens. The night the water rose fast, rescuers helped her out first. The grandchildren saved only part of the kitchen; rice, fish sauce, eggs, frozen pork and leftovers stayed behind.

Days later, when the water fell, the kitchen door opened onto a sour, rotten smell strong enough to make everyone step back. The fridge, without power for days, was leaking foul water. Rice in the bin had clumped, the wooden cupboard had swollen, the wooden cutting board was coated in mud, and a rat ran out from under the cupboard.

The grandson wanted to keep the eggs that looked fine and the dry rice on top. But a public health officer visiting the area warned that food touched by floodwater, or kept in a fridge without power for a long time, should not be eaten because it may carry germs such as Salmonella, and that older people like Auntie Juk cope less well with diarrhoea.

So the family discarded all food that had touched water, along with the wooden cutting board and soaked plastic containers. They washed the kitchen with clean water and detergent, disinfected surfaces, cleaned the fridge and propped it open to dry. Still, the sour smell hung in the kitchen for days. The right next step is to dry the kitchen fully, remove food and food containers, and only then consider ozone in the empty room to reduce lingering odour and airborne germs.

What Is Salmonella?

Salmonella is a rod-shaped bacterium that lives in the intestines of many animals, including poultry, pigs and cattle, and reptiles such as turtles, geckos and snakes. It is a major cause of food poisoning worldwide; the World Health Organization lists it among the leading causes of foodborne diarrhoeal disease.

Most people are infected by eating contaminated food, especially raw or undercooked eggs, undercooked chicken and meat, produce rinsed in unsafe water, and food cross-contaminated by a board or knife used for raw meat. It also spreads from unwashed hands after the toilet or handling animals.

Why kitchens need extra care after a flood

• Contaminated floodwater: water passing through animal pens, chicken coops, toilets and drains can carry gut germs into the kitchen
• Long power cuts: fridges and freezers stop, leaving fresh food at temperatures where germs grow well
• Soaked boards and utensils: wooden boards, wooden spoons and scratched plastic absorb water and germs
• Rats, cockroaches and reptiles escape the water into homes, especially kitchens with food
• Unsafe water: taps may stop or run cloudy, and jars or wells may be contaminated, making hand and dish washing harder
• Fatigue and haste: during cleanup, people eat stored or doubtful food for convenience

Salmonella Food Poisoning Symptoms and Who Is Most at Risk

According to the US CDC, symptoms usually start six hours to six days after infection and last about four to seven days.

• Diarrhoea, sometimes with mucus or blood
• Fever
• Stomach pain and cramps
• Nausea and vomiting
• Headache, tiredness and loss of appetite

Most people recover with enough fluids and salts, but in some cases the infection spreads from the gut into the blood and other organs, requiring hospital care. See a doctor promptly for high fever, bloody stools, vomiting that prevents drinking, diarrhoea beyond three days, reduced urine, dry mouth or dizziness, and for any young child, older adult, pregnant woman or person with weak immunity who has food poisoning. Sip oral rehydration solution often, and do not buy anti-diarrhoea medicine or antibiotics on your own.

Groups needing extra care

• Older adults: dehydrate easily and face more severe illness
• Young children and babies, especially with bottles and teats that may have touched floodwater
• Pregnant women
• People with chronic illness such as diabetes, kidney or liver disease, or on immune-suppressing medicine
• Anyone cooking for a large family or a shelter, where one contaminated dish affects many people

Food and Kitchenware After a Flood: What to Throw Out, What to Keep

Common searches are whether flood-touched food is safe and whether fridge food is still edible after a power cut. CDC and food safety agencies give these rules.

Throw out

• Any food that touched floodwater, including food in packaging water can enter: plastic bags, cardboard, screw-cap and snap-lid containers
• Rice, flour, sugar, dry goods and condiments that got wet or whose containers were flooded
• Home-preserved food in jars that touched floodwater
• Perishable fridge food after a power cut of more than about four hours: meat, eggs, milk, cooked leftovers
• Wooden boards, wooden spoons, scratched plastic containers, baby bottles, teats and pacifiers that touched floodwater
• Any food with an odd smell, colour or texture, even if it stayed dry

May be kept after cleaning

• Undamaged commercial cans, not dented, swollen or leaking: remove labels, wash and sanitise the cans, then relabel with a waterproof marker
• Uncracked metal or ceramic plates, bowls, pots and cutlery: wash with clean water and dish soap, then sanitise by boiling or soaking as advised

When in doubt, throw it out. Tasting is not a safe test, because Salmonella usually does not change how food smells or tastes.

Salmonella and Sour-Odour Hotspots in Krasae Bon Kitchens

• Fridges and freezers, where rotten food and liquid seep into door seals and drain channels
• Wooden and plywood cupboards that swelled and absorbed floodwater and food scraps
• Counters, sinks and under-sink pipes clogged with mud and grease
• Cutting boards, mortars, pestles and wooden utensils that soaked
• Rice bins, water jars and storage containers that floodwater entered
• Kitchen floors and grout holding mud and rotting scraps
• Behind cupboards and under the fridge, with rat and cockroach droppings
• Chicken coops and animal pens near the kitchen, from which floodwater carried waste

If you find rat droppings, do not sweep or vacuum them dry. Wear gloves and a mask, wet them with disinfectant first, then wipe up and seal in a bag to limit dust and germs.

The Impact on Krasae Bon Families

Health: food poisoning can dehydrate elders and young children fast, while some roads to hospital are still under water.

Money: new food, rice, condiments, boards and containers, and for some a new fridge or cupboard, while durian orchards are also damaged.

Time: sorting food, washing every utensil and cleaning the fridge take hours, alongside orchard work and house repairs.

Daily life: the kitchen is the heart of a Thai home. If it still smells sour and feels unsafe, families keep relying on instant food and handouts.

Why Washing, Wiping the Fridge or Charcoal Does Not Remove the Sour Smell

1. Hidden odour sources remain

Rotten scraps in fridge seals, the fridge drain, under-sink pipes and under cupboards are unseen sources. Remove, dismantle and wash each one.

2. Wooden cupboards hold rotten water

Swollen wooden or plywood cupboards keep releasing sour, musty odour even after wiping. Most must be removed and replaced with water-resistant shelving.

3. Charcoal and baking soda have limits

They help in small spaces such as a cleaned fridge, but not for odour filling the whole kitchen.

4. Disinfecting without washing first

Disinfectants work poorly through grease and mud. Wash with dish soap or detergent first, then disinfect per the label. Never mix bleach with ammonia or toilet cleaners.

5. Closing a damp kitchen

Damp kitchens breed mold and bacteria. Ventilate, use fans and let sunlight in where possible until every surface is dry.

6. Fragrance only masks

Air fresheners help briefly but do not reduce odour molecules or germs, and some scents can cling to food containers.

Kitchen Ozone After the 2026 Klaeng, Rayong Flood with WHD: How It Helps

World Health Disinfection's residential ozone disinfection service uses ozone gas (O3), an oxidiser that breaks down the structure of viruses, bacteria, mold and odour molecules in the air and on surfaces the gas reaches. Ozone then reverts to oxygen (O2), leaving no chemical residue. According to the company's certification data, the service was tested by Thailand's Department of Medical Sciences and Intertek (UK) for eliminating viruses, bacteria and mold at 99.99%.

Those results apply to the virus, bacteria and mold groups under the company's test conditions. This article does not claim that ozone eliminates Salmonella specifically. Salmonella belongs to the bacteria group the service targets; for detailed test data, ask WHD directly.

Be clear on this: ozone does not make flood-touched food safe to eat, and it does not replace washing dishes, disinfecting food-prep surfaces or discarding swollen wooden cupboards. All food, condiments and food containers must leave the room before treatment. Where ozone helps is in reducing sour, rotten-fridge, damp and musty odours and airborne germs in a kitchen that is already clean and dry, so it can be used again with confidence.

WHD's post-flood kitchen ozone process

1. Survey: by phone or LINE, the team reviews photos or video of the kitchen and other rooms, size, odour spots and dampness.
2. Discard, clean and dry first: throw out flood-touched food, wash and disinfect surfaces, clean the fridge, remove swollen wooden cupboards and ventilate until dry.
3. Empty the room: people, pets and plants out; food, condiments, medicine and food containers removed.
4. Seal and run: doors and windows closed, then the ozone cycle, typically about 30 minutes per zone depending on size and condition.
5. Rest and ventilate: ozone breaks down, then the room is aired for the time the technician sets.
6. Re-entry: once the technician confirms it is safe; wash dishes again before use and bring in fresh food.

Is Ozone Dangerous? Safety Rules

Ozone at disinfection levels is not safe to breathe, so treatment happens only in empty rooms, with time for breakdown and ventilation before anyone returns. Done correctly, the risk is very low.

• No people, pets or plants in the room during treatment
• Never treat food with ozone; remove all food and condiments first
• Keep the room closed and do not open it mid-cycle
• Always discard spoiled food, clean and dry the kitchen first
• Ventilate for the time the technician sets before re-entry
• Ozone does not replace a doctor for high fever, bloody stools or dehydration

10 Reasons Krasae Bon Homes Should Consider Kitchen Ozone After the 2026 Flood

1. Kitchen odour spreads through the whole house: kitchen ozone after a flood reduces what lingers after food is discarded and surfaces washed.
2. Fewer airborne germs in a kitchen that floodwater entered.
3. No chemical residue: ozone returns to oxygen, suiting food-prep areas.
4. Reaches spots you cannot wipe: behind the fridge, under counters, up to the ceiling.
5. Certified testing: 99.99% for viruses, bacteria and mold, per the company's certification data.
6. Less mold spore load and mustiness once moldy cupboards are gone.
7. Short cycles: about 30 minutes per zone plus rest and ventilation.
8. Suits village food stalls and shops that must reopen without lingering smells.
9. Other rooms at the same time, such as bedrooms and storerooms the flood left musty.
10. Planning support from sorting food to treatment day via the WHD ozone service.

Example Case: A Rice-and-Curry Stall in Durian Country

Example case to illustrate the right order of work. Not a real customer review.

Som sells rice and curry from the front of her Klaeng home, with the kitchen on the ground floor beside the stall. After the flood, her chest freezer, without power for days, smelled rotten, the wooden condiment cupboard had swollen and the floor was muddy. She sent photos over LINE. The team advised discarding all food and condiments that touched water or sat in the dead freezer, removing the wooden cupboard, washing floors and counters with detergent then disinfecting, cleaning the freezer and leaving it open to dry, and running fans until the kitchen was fully dry.

When ready, they booked ozone. Som moved every pot, plate and container out of the kitchen, and everyone, including the cat, left the house. The team sealed the area, ran each zone, then allowed breakdown and ventilation as advised.

The sour smell dropped enough for the stall to reopen. Som washed every utensil again, bought all-new ingredients and switched to raised stainless shelving. Ozone was the final step after discarding food and cleaning, not a way to rescue flood-touched food.
