Important note: This article is general information about restoring a home and kitchen after a flood. It is not medical advice. For questions about feeding, formula, stored breast milk and your baby's health, please consult your paediatrician, a nurse or a breastfeeding clinic directly. If your baby has a fever, diarrhea, vomiting, is unusually drowsy or is feeding much less than normal, see a doctor promptly.

A Story from the Field: The Smallest, Most Important Corner of the House

Mind and her husband live in a two-storey townhome in a housing estate in Khlong Sam Wa, close to Khlong Hok Wa. They recently welcomed their daughter, Khao Hom, who is now four months old. Mind breastfeeds most of the time and pumps milk so that Grandma can bottle-feed when Mind is back at work. A tin of formula sits in reserve, as their doctor suggested.

The counter next to the fridge in the ground-floor kitchen became the milk-prep corner, the one place everyone in the house knew had to be spotless. It held a bottle steriliser, a drying rack, bottle brushes, an electric breast pump, a box of pump parts, a hot-water flask, the formula tin, and a small chest freezer filled with bags of breast milk that Mind had saved one bag at a time.

In mid-September 2026, heavy rain fell for days. The canal overflowed into the estate, the ground floor flooded to around 50 centimetres, and the power went off for two days. Mind carried the baby upstairs along with the breast pump and the bottles she could grab. But the steriliser, the drying rack, the breast milk freezer and the formula on the lower shelf of the cupboard stayed in the kitchen.

When the water went down, the kitchen smelled strongly of damp and mud. The wooden cupboards under the counter had swollen, and mold spots had appeared on the doors. The formula tins on the bottom shelf were marked with a cloudy water line. The freezer, without power for so long, had thawed, and every bag of breast milk was soft. The steriliser had mud caked around its base, and the floor was slick with a thin film of slime.

Mind stood looking at the thawed milk with tears in her eyes, and the questions came all at once. Can any of this milk still be used? Can bottles that went underwater be boiled and used again? How clean does the kitchen need to be before she can make up bottles for her baby there again? If you are new parents in Khlong Sam Wa, Min Buri, Nong Chok or a nearby district, this guide is here to help.

Why the Milk-Prep Corner Needs Special Care After a Flood

1. Babies are the most vulnerable people in the house

A baby's immune system is still developing. Floodwater is often contaminated with sewage and germs such as E. coli, which can cause diarrhea, and diarrhea in a baby can lead to dehydration quickly. Anything that touches milk or goes into your baby's mouth has to be safe first.

2. Baby items are small and full of crevices

Teats, pump valves, connectors and tubing have tiny gaps where germs and silt can hide. Some parts are very hard to clean all the way through, especially if they sat in floodwater for days.

3. Long power cuts affect stored breast milk

Frozen breast milk that thawed during a power cut is something many parents find heartbreaking to lose. Whether to keep or discard it is a question for a nurse or breastfeeding clinic, not something to guess.

4. Mold in kitchen cupboards and counters

Wooden cupboards under the counter that swelled with water often grow mold inside. Mold spores can trigger allergies, and a musty kitchen makes you uneasy every time you prepare a bottle.

5. New parents are already short on sleep

Caring for a baby while cleaning up after a flood is exhausting. A clear order of work means you do not have to do the same job twice, and it saves energy for the night feeds that still have to happen.

What Not to Do with Baby Items After a Flood

• Washing bottles in tap water you are not sure about: After a flood, the water supply in some areas may have temporary problems. Follow announcements from the waterworks authority or local officials, and use bottled or boiled water until you are confident.
• Using formula from tins that touched floodwater: Even with the lid on, floodwater can seep past the rim. Throw it away and buy new.
• Using surface disinfectant on bottles or teats: Anything that goes into your baby's mouth should be cleaned according to the manufacturer's instructions, such as boiling or steaming, not with a surface disinfectant.
• Plugging in a steriliser or pump that was submerged: There is a risk of electric shock or short circuit. Have it checked by the supplier first, or replace it.
• Spraying air freshener in the kitchen: Strong fragrance is not appropriate where baby feeds are prepared, and it does nothing about the cause.

Sorting the Milk-Prep Corner: Discard, Check or Clean and Keep

Discard and replace

• Teats, silicone connectors and pump tubing that were submerged in floodwater
• Tins or bags of formula that touched floodwater, even unopened
• Bottle brushes, sponges and cloths that soaked in the water
• Unused breast milk storage bags that were in the flood

Check with the supplier or an expert first

• Bottle sterilisers, dryers and electric breast pumps that got wet
• Freezers and fridges that were submerged: have a technician check the electrics before use
• Breast milk that thawed during the power cut: ask a nurse or breastfeeding clinic

Clean and sterilise as the manufacturer advises, then keep

• Glass or hard plastic bottles with no cracks: wash thoroughly and then boil or steam according to the manual. If in doubt, replace them.
• Containers that were not submerged but sat in the damp room: wash and sterilise again before use.

Restoring the Kitchen and Milk-Prep Corner: Step by Step

1. Set up a temporary milk-prep station upstairs: A clean table, a hot-water flask and bottled water while the kitchen is not ready.
2. Have an electrician check the ground floor: Before switching on lights or plugging in kitchen appliances.
3. Remove mud and items to discard: Wear rubber boots, rubber gloves and a mask. Keep the baby upstairs during this stage.
4. Wash floors, counters and cupboards: Use clean water and detergent. Take off swollen cupboard doors to dry or replace them, then make sure everything is completely dry.
5. Professional disinfection fogging and ozone treatment: To deal with germs on surfaces, mold inside cupboards and musty odors.
6. Ventilate and set up the milk-prep corner again: Keep baby items raised off the floor and separate from the rubbish bin and the sink.

Kitchen Disinfection Fogging and Ozone Treatment from World Health Disinfection

World Health Disinfection (WHD) provides disinfection fogging and ozone treatment for homes after a flood, including kitchens where milk and food are prepared for young children.

Surface disinfection with CHEMGENE HLD4H

The team uses CHEMGENE HLD4H with an ultra-low-volume (ULV) fogger on floors, lower walls, the inside of under-counter cupboards, door frames and every surface the floodwater touched. Before fogging, the team will ask you to remove bottles, teats, pump parts, food containers and all food from the area, so they can be cleaned separately according to the manufacturers' instructions.

Ozone treatment for mold and musty odors

After fogging, the team seals the kitchen and runs an ozone treatment. Ozone gas reaches into cupboard gaps and corners that cannot be wiped, helping to destroy mold spores and break down musty and muddy odors. The dose is controlled to suit the size of the room.

Safety for homes with a baby

• Babies, adults, pets and plants must not be in the area during ozone treatment. Many families take their baby to stay with relatives for the whole day of the service.
• Move baby items, food and any good formula out of the room first.
• Appliances that cannot be moved, such as the fridge or microwave, are covered and the team uses a controlled ozone dose, because fridge door seals and some plastics can age faster with long exposure to high ozone levels.
• After treatment, open doors and windows to ventilate for the time the team recommends, then wipe the counters with clean water once more before you start preparing milk.

How the service works

1. Site survey: water level, swollen cupboards and mold spots.
2. Advice on what to throw away and what to move out.
3. ULV disinfection fogging with CHEMGENE HLD4H.
4. Ozone treatment in the sealed room.
5. Ventilation until the room is ready to use.
6. A re-check of odors and mold spots.

Why Kitchens in Khlong Sam Wa Housing Estates Stay Damp

Many housing estates in Khlong Sam Wa were built on former farmland and fish ponds, criss-crossed by canals such as Khlong Hok Wa and Khlong Sam Wa itself. The land is flat and low, so when the canals rise, water can sit in the estate roads and gardens for days before it drains. Even after it leaves the house, the ground under and around the kitchen stays saturated.

Townhome kitchens here are often at the back of the house, with a single small window or a door to a narrow service yard. They get little sun and little airflow. Built-in cupboards made of particleboard or MDF soak up water like a sponge and swell, and their backs sit tight against walls that are already damp. It is the perfect hidden place for mold to grow, and the musty smell often seems to come from nowhere because the source is behind or underneath the cabinets.

That is why, in many of these kitchens, the most effective first step is to remove the damaged cupboard doors and kickboards, let air reach the hidden spaces and dry everything thoroughly. Once that is done, disinfection fogging and ozone treatment can reach the gaps and voids that a cloth never will, and the kitchen has a real chance of staying fresh afterwards.

Setting Up a Safer Milk-Prep Corner

When the kitchen is ready again, it is a good moment to rethink the milk-prep corner so it is easier to keep clean and safer if water ever returns.

• Height: Keep the steriliser, bottles and pump parts on the counter or a wall shelf, never on low shelves or the floor.
• Separation: Leave a clear gap between the milk-prep area and the sink, the rubbish bin and raw-food preparation.
• Containers: Store clean, dry bottles and pump parts in a lidded plastic box so they stay protected from dust and splashes.
• Power: Plug the steriliser and pump into sockets well above floor level, and avoid trailing extension leads across the floor.
• Water: Keep a supply of bottled water near the corner, so you are never forced to use water you are unsure about.
• A simple routine: Wipe the counter before and after every bottle preparation, and wash hands thoroughly each time.

These are small changes, but together they turn the milk-prep corner into the calm, reliable space new parents need, especially in the middle of the night.

Planning the Day of the Service with a Baby

A treatment day goes much more smoothly when it is planned around your baby's routine. Here is a simple approach many families use.

• The day before: Pack a day bag for the baby with enough bottles, formula or expressed milk, nappies, spare clothes and the breast pump if the mother is pumping. Move all other baby items, food and good formula out of the kitchen.
• Where the baby will be: Arrange to spend the day with grandparents, relatives or friends in a home that was not flooded. A familiar person and a quiet room help the day feel normal for the baby.
• Morning of the service: One parent meets the team, shows them the kitchen and other flooded rooms, and confirms which appliances are staying and need to be covered.
• During the service: Nobody stays in the treated area. The parent can wait outside or leave and come back at the time the team gives.
• After the service: Ventilate for the recommended time, wipe the counters with clean water, then bring back the freshly sterilised bottles and set up the milk-prep corner.
• Bringing the baby home: Once the house is aired out and the milk-prep corner is ready, the family can come home and settle back into the usual feeding routine.

Looking After Yourselves, Too

New parents dealing with a flood often put themselves last. Broken sleep, worry about the baby, lost breast milk and a damaged home add up quickly. It is completely normal to feel overwhelmed, sad or frustrated, especially when months of carefully saved milk have been lost.

Accept help where it is offered. Let relatives hold the baby while you rest, or let friends help carry rubbish to the street. If you are breastfeeding and the stress seems to be affecting your supply, or if you feel low for more than a few days, talk to your breastfeeding clinic, nurse or doctor. Getting the house clean matters, but so does making sure the people caring for the baby are coping.

Before and After: Khao Hom's Milk-Prep Corner

A New Mother's Voice

"At first I didn't know where to start. The team helped us sort what to throw away and what to have the shop check, and told us to take the bottles and pump parts out to sterilise ourselves before they fogged. For the thawed breast milk, we phoned the nurse at the breastfeeding clinic. Now we're making up bottles in the kitchen again, and there's no musty smell at all."

- An example scenario from a family in Khlong Sam Wa

Be Ready if Heavy Rain Returns

• Keep spare formula, a spare set of bottles and spare pump parts upstairs in a sealed plastic box.
• Keep bottled water and a hot-water flask upstairs.
• Ask your breastfeeding clinic in advance how to handle frozen breast milk during long power cuts.
• Wipe the counters and surfaces around the milk-prep corner regularly with CHEMGENE spray, then wipe again with clean water.
• If dust mites build up in your baby's room, consider a dust mite removal service.

Frequently Asked Questions

1. Can bottles that were submerged be boiled and used again?

Glass or hard plastic bottles without cracks may be washed and then boiled or steamed according to the manufacturer's instructions and reused, but teats and silicone parts should be replaced. If you are unsure, replacing the whole set is the safest option.

2. Can breast milk that thawed during the power cut still be given to my baby?

Please ask a nurse, paediatrician or breastfeeding clinic, because it depends on several factors, such as how long it was thawed and how warm it became.

3. Will fogging leave residue on the kitchen counter?

The team will advise on ventilation after the service and recommend wiping the counters with clean water again before you prepare milk or food.

4. How long does my baby need to be away?

The team gives an estimated time after the survey, including ventilation. In general, we recommend your baby stays elsewhere for the whole day of the service.

5. Should we treat only the kitchen or the whole house?

Every area the water reached should be treated, and your baby's bedroom too if it is damp or musty. The team will assess this after the survey.

6. Which areas do you cover?

Khlong Sam Wa and nearby districts such as Min Buri, Nong Chok, Sai Mai, Bang Khen and Lam Luk Ka, as well as other areas of Bangkok and the surrounding provinces.

7. Can you schedule around feeding times or a parent's return to work?

Yes. Let the team know your baby's routine and any dates that matter, such as when a parent goes back to work, and we will try to book a day that keeps disruption to a minimum and leaves enough time for ventilation before the family returns.
