A Story from the Field: The Morning Wanphen Opened Her Fridge

On the bank of the Tha Chin River in Si Prachan district, Suphan Buri, there is a two-storey wooden house that doubles as a small curry-and-rice shop. For more than ten years, "Wanphen" has cooked there every morning. Rice farmers on their way to the fields, construction workers, and schoolchildren with a few coins in their pockets stop by to pick up bags of curry, stir-fried vegetables and fried eggs. The ground-floor kitchen is not just a room in her house. It is the family's livelihood and, in many ways, the heart of the neighbourhood.

This year the river came into the house almost to waist height and stayed for close to two weeks. The electricity was cut on the first day. Wanphen and her husband managed to carry some things upstairs: the rice cooker, a few bags of dry goods, the children's school books. But the two-door refrigerator, the chest freezer they used for ice, the old wooden food cupboard, the heavy pots and woks, and the thick tamarind-wood chopping board all stayed downstairs, under brown water.

On the day the water finally drained away, Wanphen was the first to wade back through the mud into the kitchen. The smell hit her before she reached the door. When she pulled open the fridge, the minced pork, chicken and coconut milk she had stocked for the week had turned into a grey, sour mess, and cloudy liquid ran out of the freezer compartment onto the floor. The wooden cupboard had swollen so badly that its doors no longer closed, and green and black spots of mold had spread along the corners and shelves. Her pots and pans were coated in a layer of silt so thick that she could not see the metal underneath.

Over the next three days she scrubbed with washing powder and household bleach until the skin on her hands stung. The tiles looked cleaner, but the sweet, rotten smell kept drifting back, especially in the evening when the doors were closed. Her seven-year-old daughter began to complain of stomach aches. Wanphen did not dare reopen the shop. She kept asking herself the same questions: Which of these things can I keep? Which should go straight to the rubbish pile? And how do I make this kitchen genuinely clean again, not just clean-looking?

Wanphen's story is a composite of what our team hears again and again from families in Si Prachan, Don Chedi, Sam Chuk and the other riverside communities along the Tha Chin in 2026. This article walks through the kitchen one area at a time, from the refrigerator to the food cupboard to everyday cookware, and then explains how professional disinfection fogging and ozone treatment can bring a flooded kitchen back to a safe, fresh-smelling state.

Why the Kitchen Is the Riskiest Room After Floodwater Recedes

Floodwater is never just rainwater. As it moves through a district it picks up whatever it passes: overflowing drains, septic tanks, animal pens, fertiliser, fuel, pesticides from the fields, and rotting vegetation. By the time it reaches a kitchen, it has become a mixture that can carry bacteria, viruses and parasites. Every surface it touches becomes a possible source of contamination, and in a kitchen those surfaces are exactly the ones that touch food.

The kitchen also has a unique combination of factors that makes the problem worse. It contains spoiled food that feeds bacteria, grease that traps dirt and holds odors, wood and particle board that soak up water, and appliances with hidden insulation, fans and drip trays. Warmth from Thailand's climate and the high humidity after a flood complete the picture. In short, the kitchen is the room where microbes have the most to eat and the most places to hide.

1. Health risks

• Diarrhoea and food poisoning. Bacteria from sewage, such as E. coli, can remain on chopping boards, plates, spoons and countertops. If those surfaces are only rinsed, the germs can move straight into the next meal.
• Leptospirosis. Rats escape rising water by climbing into food cupboards and the warm space behind the fridge. Their urine can contaminate surfaces and standing water. Cleaning with bare hands, especially hands with small cuts, raises the risk.
• Mold allergy and asthma. Wooden cabinets, the wall behind the stove and the rubber seals of the fridge door are some of the first places mold appears. Spores released into the kitchen air can trigger coughing, sneezing, a blocked nose and breathing difficulty, particularly in children and older adults.
• Skin infections and irritation. Long hours of contact with mud and strong cleaning chemicals dry and crack the skin, which then becomes an easy entry point for infection.

This information is general guidance, not medical advice. If anyone in the household develops a high fever, painful calves, severe diarrhoea or difficulty breathing after a flood, seek medical care promptly and follow the advice of Thailand's Department of Disease Control.

2. Money and time

A refrigerator, a freezer, a food cupboard and a full set of cookware add up to a significant sum. Throwing everything away means a large and sudden expense at a time when many families have already lost income. Keeping everything without treating it properly means scrubbing the same surfaces again and again while the smell keeps returning. For households that sell food from home, every day the kitchen stays closed is a day of lost earnings.

3. Reputation

In a small community, everybody knows everybody. If customers hear that someone got sick after eating from a particular shop, or if they smell something sour as they walk past, trust that has been built over many years can disappear in a matter of days. For a home-based food business, a clean kitchen is not only about health; it is about protecting the family's name.

Sorting the Kitchen: What to Throw Away and What You Can Save

Before you start scrubbing, take an hour to sort everything into three groups. This simple step stops you from wasting energy on items that should never be used again, and it also stops you from throwing away things that can safely be rescued.

Group 1: Discard immediately

• Any food that touched floodwater, and any food that sat in a fridge or freezer during a long power cut.
• Canned food that is swollen, dented, leaking or rusted along the seams.
• Bottles and jars with screw caps, crown caps, corks or pop-tops, because floodwater can seep under the lid.
• Condiments and sauces in plastic bottles, and any rice, flour, sugar, dried chilli or spices that got wet.
• Wooden chopping boards, wooden ladles, wooden spoons, bamboo chopsticks, kitchen sponges and cleaning cloths. Porous materials absorb contaminated water and cannot be reliably disinfected.
• Soft plastic containers and any plastic or melamine items with cracks or deep scratches.

Group 2: Can be saved with proper cleaning and disinfection

• Stainless steel and aluminium pots, woks, ladles and cutlery.
• Ceramic plates and bowls without cracks or chips.
• Glasses and glass storage jars with smooth surfaces.
• Hard, smooth plastic containers that show no cracks.

Group 3: Needs assessment before deciding

• Refrigerators, freezers, electric stoves, microwaves, rice cookers and water heaters. These must be checked by a qualified electrician or appliance technician before you plug them in.
• Wooden or particle-board cupboards. If the panels have swollen, delaminated or show mold growing into the wood, they usually need to be replaced. Solid hardwood furniture that is structurally sound may be cleaned, dried and treated.
• Built-in cabinets under the sink. Check the back panels and the base, where water often sits unnoticed for days.

A special word about the refrigerator

The fridge is often the single biggest source of odor after a flood. If floodwater reached the compressor or the control board, do not switch it on until a technician has inspected it. Even if the appliance itself survives, the smell of spoiled food can soak into the plastic liner, the foam insulation behind it, the drain channel and especially the rubber door gasket. To give it the best chance, remove every shelf, drawer and tray and wash them separately. Clean the drain hole and drip tray. Wipe deep into the folds of the door gasket with a disinfectant. Then leave the doors open and let the appliance dry completely before any deodorizing treatment.

Safe DIY steps for cookware

1. Always wear rubber gloves, rubber boots and a mask, especially if you have any cuts on your hands or feet.
2. Scrape off as much mud as possible, then wash items in clean water with dishwashing liquid.
3. Boil metal pots, cutlery and heat-safe dishes, or soak them in a disinfectant used according to the label directions. Let them air-dry on a clean rack.
4. Wipe countertops, the sink and cupboard fronts with disinfectant, paying attention to edges and corners where mud collects.
5. Keep doors and windows open for ventilation, and never mix different cleaning chemicals together.

After these five steps the kitchen will look much better. But the places you cannot see, such as the air vents behind the fridge, the cavity under the sink and the joints in wooden cupboards, can still hide germs and odor. That is why the next stage matters.

Why the Usual Fixes Do Not Remove the Rotten Smell

Almost every family tries the same set of remedies first. They are understandable, and some of them are useful, but on their own they rarely solve the problem completely.

• Bleach on its own. Bleach can disinfect the surfaces you physically wipe, but it does not reach into cupboard joints, the condenser area behind a fridge, or the pores of wood. Organic matter such as mud also weakens it quickly. Worse, mixing bleach with certain toilet or drain cleaners can release dangerous gases in a small, closed kitchen.
• Running fans or leaving windows open. Air movement helps things dry, which is important. But it does not destroy odor molecules or mold spores. As soon as the house is closed up again in the evening, the smell drifts back.
• Air fresheners, charcoal and coffee grounds. These either cover the smell with a stronger scent or absorb a small portion of it. The source, which is often embedded in wood, insulation and rubber, is still there.
• Painting over or adding laminate. If the wall behind the stove or under the counter is still damp and moldy, mold will grow again underneath the new surface. Within a few weeks the musty smell returns, often along with peeling paint.

The lesson is simple: manual cleaning is essential and must come first. But to make a flooded kitchen truly safe, you also need a method that reaches every hidden corner and deals with odor at its source rather than masking it.

The Solution: Chemgene HLD4H Disinfection Fogging and Ozone Treatment by WHD

World Health Disinfection (WHD) helps flood-affected homes recover with two complementary steps that together cover what manual cleaning cannot.

Step one: disinfection fogging

Our disinfection spraying service uses CHEMGENE HLD4H applied with ultra-low-volume (ULV) fogging equipment. Instead of large wet droplets, the machine produces a very fine mist that drifts into places a cloth or brush cannot reach: under the sink, behind and beneath the fridge, inside cupboard frames, along the top of wall tiles and into the corners of the ceiling. The aim is to reduce bacteria, viruses and fungi on the surfaces of the room, including the many surfaces that nobody thinks to wipe.

Step two: ozone shock treatment

Our ozone treatment service uses a high-output ozone generator in the closed kitchen. Ozone is a gas, so it travels into gaps that liquid mist cannot: wood grain, the space between a cupboard and the wall, the insulation around a fridge, and the folds of fabric curtains. Ozone is a strong oxidiser. It breaks down the molecules responsible for rotten and musty odors and damages mold spores, which is why it removes smells rather than simply covering them.

How a kitchen job works, step by step

1. Site survey. We look at how high the water reached, where mold is visible, where the smell is strongest and what needs to be moved out before treatment.
2. Clean-up and sorting advice. We advise which items should be discarded and which can be saved, and we ask that heavy mud be removed first so that the disinfectant and ozone can work directly on surfaces.
3. Disinfection fogging. We fog floors, walls, countertops, the sink area, around drains, inside open cupboards and around large appliances.
4. Ozone shock. The room is closed and treated for a period suited to its size and the severity of the odor. The ozone dose is controlled, and sensitive electronics, rubber items and anything delicate are covered or removed beforehand.
5. Ventilation. Doors and windows are opened so the remaining ozone can revert to oxygen. People only re-enter once the space has been properly aired.
6. Re-check and aftercare. We check for remaining odor and risk points and give practical advice on keeping the kitchen dry so mold and smell do not return.

Ozone safety: No people, pets or plants may be inside the treated area during ozone treatment. The space must be ventilated thoroughly before anyone goes back in. All fresh food should be removed. Sensitive electronic equipment and rubber components should be covered or taken out as our team advises, and the ozone dose is controlled to suit the room.

10 Reasons to Let WHD Help Restore Your Kitchen After the Flood

1. Reach. A fine ULV mist travels under the sink, behind the fridge and along cupboard edges, places a cloth simply cannot get to.
2. A purpose-made disinfectant. We use CHEMGENE HLD4H, formulated for surface disinfection work.
3. Odor removed at the source. Ozone treatment breaks down rot and musty odor molecules instead of hiding them under perfume.
4. Fewer mold spores. Treating the air and surfaces helps reduce spores that trigger allergies and asthma.
5. No dangerous chemical mixing. You do not need to experiment with combinations of household products that can release toxic gases.
6. Clear advice on what to keep. Knowing what can be saved and what must go helps you avoid unnecessary replacement costs.
7. Faster reopening. Home-based food sellers can get back to cooking sooner and with more confidence.
8. Controlled and safe process. The ozone dose is matched to the room, with a clear ventilation step before re-entry.
9. Whole-property protection. Standing water after a flood breeds mosquitoes, so you can add our mosquito spraying service around the house.
10. Easy daily follow-up. For everyday wiping of counters and handles, the CHEMGENE HLD4H 750 ml spray is a convenient option.

Before and After a Kitchen Restoration

What Our Customers Say

"At first I thought I could handle it myself. I scrubbed for three days and the smell would not go away. After the team fogged the kitchen and ran the ozone treatment, and we aired the room the way they told us, I walked in the next morning and could breathe properly again. They also told me honestly that the old chopping board and the wooden cupboard should be replaced, which saved me from wasting more effort on things I should not keep."

Frequently Asked Questions

Can I still use a refrigerator that was flooded?
It depends on whether water reached the compressor and the electrical controls. Have a technician check it before plugging it in. If they confirm it is safe, wash every removable part, clean the drain channel and door gaskets, let it dry completely, and then treat the odor.

Do I have to throw away pots and plates that were under water?
Not necessarily. Stainless steel and aluminium pots, woks, cutlery, and ceramic plates without cracks can be washed with soapy water, boiled or disinfected, and reused. Wooden utensils, sponges and cracked plastic should be discarded.

How long after ozone treatment can we use the kitchen?
Our team will tell you the timing based on the size of the room and the treatment level. After treatment the space must be ventilated properly before people, pets or plants return.

Will ozone damage my kitchen appliances?
We control the ozone dose for the room, and we cover or remove sensitive electronics and rubber items before treatment to protect them.

Should I clean up the mud before you arrive?
Yes, if you can. Removing heavy mud and dirt first allows the disinfectant and the ozone to work directly on surfaces. If you are unsure where to start, we will advise you during the survey.

What else should a home food business do before reopening?
Use clean water for cooking and washing, replace chopping boards and sponges, disinfect food-contact surfaces regularly, and follow food sanitation guidance from Thailand's Department of Health.

Do you work outside Si Prachan?
Yes. We help homes and businesses across Suphan Buri and other flood-affected provinces. Contact us to check scheduling for your area.

Keeping the Kitchen Fresh in the Weeks After Treatment

Professional treatment gives you a clean starting point, but how you use the kitchen during the following weeks decides whether the smell stays away. Floodwater often leaves moisture trapped in walls and under floors long after the surface looks dry, and that hidden moisture is what allows mold to return. A few simple habits make a big difference.

• Keep air moving. Open windows during the day and use a fan to push damp air outside. If you have a dehumidifier, run it in the kitchen for the first few weeks.
• Do not push furniture tight against damp walls. Leave a gap of a few centimetres behind cupboards and the fridge so air can circulate.
• Empty and wipe the fridge regularly. Check the drip tray and drain channel weekly, and wipe the door gaskets where moisture collects.
• Take out kitchen waste every day. Rotting food scraps add to odor and attract flies, cockroaches and rats, which are already more active after a flood.
• Watch for warning signs. New spots on walls, a musty smell that returns when the room is closed, or paint that starts to bubble are signs of trapped moisture. Deal with them early.
• Disinfect high-touch points. Handles, taps, light switches and counters should be wiped daily with a suitable disinfectant, especially if you sell food.

If you notice the odor returning or new mold appearing despite these steps, it may mean there is moisture deep inside a wall or under the floor. In that case, contact us so we can reassess the area and advise whether a second treatment or structural drying is needed.
