A Story From the Field: The Stockpot That Went Quiet for a Week

"Auntie Daeng" has sold Hainanese-style chicken rice from a shophouse beside a morning market in the town centre of Mueang Sing Buri for more than twenty years. Her day starts at three in the morning. She poaches the chickens, cooks the fragrant rice in a huge pot, and simmers a clear bone broth that regulars sip before they go to work. Her daughter fries patongko dough sticks and brews old-style Thai coffee at a little stand by the door. The shop has six stainless-steel tables, a chopping counter at the front, a glass cabinet where the poached chickens hang, and a small back kitchen where sacks of rice, cans of cooking oil and crates of soy sauce bottles usually sit on the floor.

When the Chao Phraya River rose in October, the water crept slowly into the market lane and then into the shop until it reached about mid-shin. Auntie Daeng and her daughter managed to carry the rice cookers and the big pots upstairs in time. But the rice sacks, the crates of seasoning, the bags of shallots and garlic and the old refrigerator in the back were too heavy to move. The shop stayed closed for almost a week.

On the day the water finally drained away, the first thing she noticed was the smell. A room that used to smell of ginger and chicken broth now smelled damp and stale, with an earthy, muddy odour rising from the floor. There was almost an inch of clay-like silt under the chopping counter. The stainless-steel table legs carried a clear tide line. Small black spots of mold had appeared on the back kitchen wall exactly where the water had reached, and the rice bags on the floor had swollen and begun to smell sour.

Regular customers kept calling: "Auntie, when are you opening? We miss your chicken rice." But she did not feel ready. If the musty smell was still there, customers would notice the moment they walked in. More importantly, she simply did not want anyone eating food cooked in a shop she did not believe was truly clean.

Auntie Daeng's story is a realistic scenario of the kind our team sees again and again in breakfast shops around markets after floodwater recedes, whether the shop sells chicken rice, rice porridge, boiled rice soup, fried dough sticks or old-fashioned coffee. This article explains why these shops need extra care, what to do first and in what order, and exactly where professional disinfection fogging and ozone treatment fit into the recovery.

Why Market Breakfast Shops Need Extra Care After a Flood

Floodwater that flows through a market is never just rainwater or clean river water. Before it reaches a shop, it has usually passed through storm drains, sewer chambers, rubbish bins, fish stalls, meat stalls and public toilets. It carries mud, waste and many kinds of germs, and it leaves them behind in every corner of the shop it enters. A market food shop is therefore one of the places where post-flood hygiene matters most, because whatever stays in the building can end up close to the food that is prepared there every morning.

Health risks for staff and customers

• Diarrhoea and food poisoning. Bacteria from sewage, such as E. coli, can remain on floors, counters, chopping boards and containers. If cleaning is incomplete, contamination can travel from those surfaces to food.
• Leptospirosis. Market rats often flee rising water into shops. Their urine mixes with floodwater and mud and is the source of this disease. Anyone who wades through water or cleans the shop without rubber boots and gloves is at risk, especially if they have cuts on their feet or hands.
• Skin infections. Cooks often have small cuts on their hands from chopping chicken or slicing vegetables. Contact with mud and dirty water can infect those wounds.
• Allergies and breathing problems. Mold spores growing on walls and under counters can make people with allergies or asthma cough, sneeze and feel short of breath. Breakfast cooks spend hours inside the shop before sunrise, often with the shutter half closed, so they breathe that air for a long time.

Risks to income and reputation

A breakfast shop survives on regulars. People who eat the same chicken rice every morning remember not only the taste but also the feel of the place. If a shop reopens too early while the musty smell is still there, customers may say nothing at all and simply start eating somewhere else. In an age when everyone photographs their food and posts it online, a single picture of mold on the wall behind the counter can damage a reputation that took years to build.

On the other hand, staying closed for too long means losing income every single day, both for the owner and for the staff who depend on the shop. Suppliers have to be told, regular orders disappear, and the longer the shutter stays down, the more customers form new habits. The goal is therefore not to rush and not to wait endlessly, but to follow a clear sequence that makes the shop genuinely clean and lets the owner reopen with confidence.

Step One, Done by the Shop: Throw Away Flood-Touched Stock and Sort Equipment Clearly

Before thinking about fogging or ozone, a food business owner must start by sorting everything in the shop. No disinfection method can make food that has been in floodwater safe to eat again. This is the most important rule in the whole recovery, and it is not negotiable.

• Throw away immediately: rice, beans, flour, sugar, shallots, garlic, ginger, fresh vegetables, chicken and every ingredient that touched floodwater. This also includes food in a fridge that was flooded or lost power for a long time, seasoning bottles with corks or screw caps that water could seep past, and any paper packaging, foam boxes or plastic bags meant for food.
• Throw away or seriously consider replacing: wooden chopping boards, wooden spatulas, wooden chopsticks, hand towels, sponges and any porous equipment. Mud and germs soak deep into these materials and are very hard to remove.
• Wash and keep using: stainless-steel pots, trays, plates, metal spoons and forks, and basins without cracks. Scrub them with clean water and dishwashing liquid, then scald or sanitise them in the way the shop normally does, and let them dry in a clean place away from the flooded area.
• Have a technician check first: fridges, chest freezers, rice cookers, power sockets and gas stoves that were underwater. An electrician or qualified technician should inspect them before they are switched on again.

Once sorting is done, shovel out the mud, wash the floor, walls and counters with clean water and a cleaning detergent, and open doors and windows to let air move through. Then move all food, newly bought ingredients, washed containers and food-contact equipment out of the shop before our team arrives to disinfect and ozone-treat. In a restaurant, disinfection is always carried out on an empty space, never on food.

It helps to take a few photographs of the shop at this stage, before and after the mud is removed. They are useful for any insurance or assistance claims and also help our team understand where the water reached and which areas were worst affected.

Why the Usual Fixes Are Not Enough

Pouring bleach on everything. Bleach can disinfect smooth surfaces, but when it is poured onto mud that has not been washed away, its effect drops sharply. It also cannot reach the gaps under counters, the space between the wall and the cabinets, or a damp ceiling. And a strong chlorine smell is not what any food shop wants hanging in the air when customers arrive for breakfast.

Running fans for days. Fans help surfaces dry faster, which is good, but they do not kill anything. They can even blow mold spores around the room and spread them to places that were never wet.

Air fresheners or incense to mask the smell. A strong fragrance can hide a musty odour for a few hours, but the odour molecules and the cause of the smell are still there. After a day or two the musty smell returns. Heavy perfume also clashes with the aroma of food, which is the very thing that draws customers into a chicken rice shop.

Painting over mold stains. If the wall is still damp, mold under the new paint keeps growing and will push the paint into blisters or new black spots within a few weeks. Moisture and mold must be dealt with before repainting.

Reopening and hoping the smell fades. Some owners reopen quickly and expect the smell to disappear on its own as the shop is used again. In a closed shophouse with a rolling shutter, damp air stays trapped overnight, and the smell is often strongest exactly at 3 a.m. when cooking begins.

The Solution: CHEMGENE HLD4H Disinfection Fogging Plus Ozone Treatment of the Empty Shop by WHD

The World Health Disinfection (WHD) service is designed to pick up where the shop's own cleaning leaves off. It combines two methods that support each other.

1. Ultra-low-volume (ULV) disinfection fogging with CHEMGENE HLD4H disinfectant. The fine droplets drift into places that cloths and brushes cannot reach, such as the underside of counters, behind the glass cabinet, the edges of the rolling shutter and the joint between floor and wall. This reduces bacteria, viruses and mold on surfaces throughout the shop.

2. Ozone shock treatment with a controlled ozone generator. Ozone is a gas that spreads into the whole room. It helps destroy airborne mold spores and breaks down the molecules responsible for musty, muddy and stagnant-water smells that have soaked into the shop.

Fogging deals mainly with surfaces, while ozone deals with the air and with odour trapped in the room. Used together, after proper cleaning, they give a far more complete result than either method alone.

How the service works for a chicken rice or breakfast shop

1. Site survey. The team checks the size of the shop, how high the water rose, where mold has appeared and how the back kitchen and storage areas are laid out.
2. Preparation advice. We confirm that flood-touched stock has been discarded, mud has been removed and the floor washed, and that all food, ingredients, food containers, plants and pets have been moved out.
3. Disinfection fogging. The team fogs the floor, walls, counters, tables, chairs, rolling shutter, toilet and rubbish area.
4. Ozone treatment. The shop is closed and treated with ozone for a period suited to its size. Nobody may enter during this time.
5. Ventilation. The shutter and windows are opened so that air can circulate until the ozone has broken down, before the owner goes back in.
6. Re-check and advice. The team walks through the shop again to check smell and surfaces and gives advice on controlling moisture in the first week.

Disinfection fogging and ozone treatment help reduce germs, mold and odours in the shop space. They do not replace the everyday kitchen hygiene that every food business must keep up, and they are not a certification of food safety. If you are unsure about reopening a food business, ask your local public health officer or municipality.

Before and After: A Chicken Rice Shop's Recovery

An Owner's Voice (Example Scenario)

"At first I thought washing the shop myself would be enough. I washed it three times and the smell was still there. When the team came, they told me to throw out all the rice and seasonings that had been in the water first, and then they fogged and ran the ozone while the shop was empty. The next morning there was no mud smell. On the first day back, my regulars asked what I had done because the shop felt fresher, and I simply told them."

Frequently Asked Questions

Q: After disinfection, can I use the rice or seasonings that were in the floodwater?
A: No. Every food and ingredient that touched floodwater must be thrown away. Fogging and ozone are applied only to the empty shop space, never to food.

Q: What must be moved out before ozone treatment?
A: All food, ingredients, food-contact containers, plants and pets. Every person must be outside. Sensitive electronics should be covered or removed.

Q: How long after ozone treatment can I go back in?
A: The shop must be ventilated until the ozone has broken down. The team will tell you a suitable time based on the size of the shop and the conditions on site.

Q: Do I need to wash the counters again before cooking?
A: Yes. Food-contact surfaces such as the chopping counter, boards and trays should be washed again using the shop's normal routine before cooking begins.

Q: There is black mold on the wall. Will I still need to repaint after ozone?
A: Ozone reduces spores and odour, but staining embedded in the plaster may remain. Wait until the wall is completely dry, then scrape and repaint with a paint suitable for damp areas.

Q: My shop is a single shophouse unit. Is it too small for the service?
A: Not at all. The team adjusts the amount of disinfectant and the ozone time to the space. Contact us for an on-site assessment.

Q: My family lives upstairs. Can the living area be treated at the same time?
A: Yes. Many shops are shophouses with living quarters above. See our page on residential ozone disinfection and plan the whole building in one visit.

Tips for the First Week After Reopening

• Open the shutter and run the kitchen extractor fan after closing every day to push out trapped moisture.
• Store new rice and seasonings on shelves well above the floor, never on the floor itself.
• Check the back kitchen wall every two or three days. If new mold spots appear, wipe them promptly and let our team know.
• Check the rubbish area and the drain in front of the shop so water does not pool, since standing water breeds mosquitoes and smells.
• Staff should wear gloves when washing areas that still have mud and wash their hands every time before handling food.
• Keep a simple cleaning log for the first few weeks so everyone on the team knows what has been done and when.

Planning the Reopening Day Without Rushing

Many owners ask us how long the whole process takes. The honest answer is that it depends on how quickly the shop can complete its own sorting and cleaning, how damp the walls still are, and whether electrical equipment needs repair. Fogging and ozone treatment themselves usually fit into a single visit for a shophouse, but the steps before them cannot be skipped.

A practical timeline many market shops follow looks like this. On the first days after the water drains, the owner and staff throw away flood-touched stock, remove mud and wash every surface. While the walls dry, an electrician checks the fridge, freezer, rice cookers and sockets. Next, the WHD team carries out disinfection fogging and ozone treatment in the empty shop, followed by ventilation. After that, the owner washes food-contact surfaces again, brings in new ingredients, places them on raised shelving and does a trial cook for family or staff. Only then does the shutter go up for customers.

It is also worth telling regulars what is happening. A short message on the shop's LINE group or Facebook page saying that the shop is closed for cleaning and disinfection, and will reopen on a certain date, keeps customers informed and shows that the owner takes hygiene seriously. Customers tend to return to a shop that was honest about the flood rather than one that reopened quietly while it still smelled damp.
