What Happened at Rangsit Market, Pathum Thani

According to a Thai PBS report dated 27 September 2026, Rangsit Market was flooded across almost the entire market and most shops were closed. At the same time, Khlong Rangsit Prayoonsak, the canal running through the area, was at red-flag status, a warning of high water, and overflowed onto roads and into homes.

The same report said roads alongside Khlong Rangsit were under roughly 15 to 60 centimetres of water depending on location, and that pumps had been deployed at 16 points to drain the area.

These details describe the situation on the report date. Canal and road levels change daily, so vendors, residents and commuters in the Rangsit area should keep following announcements from Pathum Thani province, local authorities and market management.

Why a Flooded Fresh Market Is a Bigger Hygiene Problem Than an Ordinary Flood

A fresh market is where raw food, water and large numbers of people meet every day. When floodwater comes in, everything in the market is stirred into the same water.

• Floodwater collects waste from many sources: the overflowing canal, roadside drains and the market's public toilets. Water that reaches the stalls may contain sewage.
• Spoiled food. When most shops close suddenly, meat, seafood and vegetables left behind can rot and mix with the water, feeding bacteria.
• Drains and grease traps. Markets have many gutters and grease traps. Floodwater lifts the sediment and fat inside them and coats floors and stall legs.
• Rats and insects. Markets attract rats because of food waste. In a flood they climb onto stalls, shelves and roofs and may leave urine where people will later touch.
• Countless food-contact surfaces. Chopping boards, knives, trays, scales, basins, ice boxes, display fridges and stall tables are all surfaces where food will be placed directly once trading resumes.

That is why reopening after the water recedes should not mean hosing off mud and putting stock back out. It should be a structured recovery that protects vendors, customers and the market's reputation.

Example Case: Auntie Juk's Pork Stall After the Water Drops

This is an illustrative scenario based on common situations in flooded markets. It is not about any real person in the news report.

Auntie Juk has sold pork at a fresh market in Pathum Thani for more than twenty years. The day the water came in, she packed the remaining meat into an ice box and hurried home, where the street was also starting to flood. The market stayed shut for days, and with it her daily income.

When the water went down she returned to find a mud line across her stainless steel table. Her large wooden chopping board, used for years, was waterlogged and smelled. The plastic ice box held cloudy water, the scale was caked with silt, and the floor around the stall was slick with slime. Regular customers were calling to ask when she would reopen, and she wanted to as soon as possible, because every closed day meant lost money.

Her question is the same as that of hundreds of other vendors: if she just washes with water and detergent and puts the pork out, is that safe? And if a customer gets sick, what happens to a business built over twenty years?

Germs Floodwater Brings into a Fresh Market, and Who Is Most at Risk

The WHO, the US CDC and Thailand's Department of Disease Control all warn that food- and waterborne illness tends to rise after floods. In a fresh market, these are the germs to watch.

Food-poisoning bacteria: E. coli and Salmonella

E. coli signals faecal contamination, and Salmonella is a leading cause of food poisoning linked to meat, eggs and poultry. If boards, trays or tables touched by sewage-tainted water then hold raw meat, bacteria can move from surface to food and from food into customers' kitchens. Undercooking or cross-contamination at home can then cause diarrhoea, vomiting, stomach pain and fever.

Leptospirosis

Markets often have many rats, and Leptospira bacteria in rat urine spread through floodwater and mud. Vendors who wade in to rescue stock or stand in water for hours cleaning stalls, especially with cuts on their feet, are at risk. The Department of Disease Control advises anyone with a sudden high fever, headache, muscle pain especially in the calves, or red eyes after flood exposure to see a doctor promptly and mention it.

Viruses spread by hands and surfaces

Norovirus and rotavirus cause diarrhoea and spread easily through hands, food and contaminated surfaces. Markets are full of shared touch points: rails, baskets, bags, cash and scales. Crowded, semi-enclosed markets also help respiratory viruses like influenza and RSV spread, and parents bringing small children should be alert to hand, foot and mouth disease, which spreads through contact.

Mould on wood, tarpaulins and damp corners

Wooden boards and shelves, sun tarps and corners of stalls stay damp long after the water recedes, ideal for mould. WHO and CDC advise cleaning and drying within 24 to 48 hours to limit mould. Beyond the musty smell, mould can contaminate dry goods sold in markets, such as rice, beans, dried chillies and spices.

Who is most at risk

• Vendors and market workers, who wade, clean and carry stock and have the longest exposure.
• Young children and older shoppers, whose defences are weaker and who dehydrate quickly with diarrhoea.
• Pregnant women, who need to be especially careful about food poisoning.
• People with chronic illness such as diabetes, kidney disease or weakened immunity.
• Food sellers and restaurants that buy ingredients at the market to cook and resell, multiplying the impact if ingredients are contaminated.

The Layers of Impact on Market Vendors

• Immediate loss of income. Most fresh-market vendors live day to day; every closed day hits stall rent, household bills and school fees.
• Lost stock. Fresh produce left behind, wet dry goods and soaked packaging all have to go.
• Damaged equipment. Fridges, digital scales, mincers and extension leads that went under need checking or replacing.
• Customer trust. The biggest hidden cost. One case of food poisoning spreads by word of mouth faster than the flood itself.
• Vendors' own health. Wading, working in damp conditions and the stress of lost income take a toll on body and mind.

Spending one more day to clean and disinfect properly protects long-term income. It is not wasted time.

Why Detergent or Bleach Alone Does Not Fully Solve the Problem for Food Stalls

Many vendors already scrub with detergent and splash bleach at closing time, a good habit. After a flood, though, the limits matter:

• Detergent cleans but is not designed to disinfect. Washing is vital because it removes mud and fat, but germs can survive in knife grooves on boards and joints in tables.
• Bleach corrodes metal. Stainless tables, scales, fridge trims and aluminium tools can stain or pit with frequent or strong bleach.
• The smell lingers. Chlorine odour on a food stall is unwelcome to vendors and shoppers, and under low market roofs with poor airflow it builds up.
• Mixing mistakes. With everyone cleaning at once, someone may combine bleach with toilet cleaner or ammonia products, which can release dangerous gas.
• Grease and blood reduce effectiveness. Meat and fish stalls carry heavy organic soil, and if it is not fully removed, disinfectant action drops.
• No lasting protection. Once dry, surfaces are immediately exposed again to hands, customers and splashes.

The Solution for Stalls After the Flood: CHEMGENE HLD4H Medical-Grade Disinfectant

According to the product information, CHEMGENE HLD4H is a medical-grade high-level disinfectant made in England and used in hospitals, clinics, laboratories, schools, offices, airports, homes and elderly and child care settings.

Organisms listed: the product information lists bacteria, fungi and mould, mycobacteria, Salmonella and viruses including influenza H1N1, RSV, norovirus, hand, foot and mouth disease virus and SARS-CoV-2. The product page states it kills within 1 minute, is 99.85% effective against COVID-19, and gives residual surface protection for up to 14 days.

Kind to market equipment: per the product information it is non-corrosive to stainless steel, aluminium, rubber, plastic and fibreglass, the main materials of stall tables, trays, scales, ice boxes and basins. It is biodegradable and stated to be safe for people, pets and medical equipment when used as directed.

Tests and approvals cited: Mahidol University, NHS England, ISO 9001:2015, ISO 13485, SGS, Intertek, CE, and EN 13727, EN 14348, EN 13624 and EN 14476.

Dilution: 1:30, 1:50, 1:60, 1:100 and up to 1:200 per the product information. Choose the dilution and contact time on the label for each job.

Seven Steps to Reopen a Market Stall Clean and Germ-Safe

The key rule: remove the mud and wash the stall clean first, then apply CHEMGENE HLD4H to cleaned surfaces at the label dilution and contact time.

1. Safety first. Wear rubber boots, long gloves and a mask and cover any cuts. Make sure stall power is off and do not plug in a submerged fridge or mincer until an electrician has checked it. Keep the area ventilated.

2. Discard what cannot be saved. Throw away fresh and dry food, condiments and packaging that touched floodwater, and anything from fridges left without power. Discard soaked tarps, sponges, cloths and fabric bags. Replace wooden boards that are swollen, cracked or deeply scored, because they are hard to clean.

3. Shovel mud and clear the gutter in front of the stall, and coordinate with market management on central drains and grease traps.

4. Wash every surface with detergent. Scrub tables, legs, undersides, shelves, trays, basins, baskets, ice boxes, the outside of scales (keeping water out of the electronics), knives and boards. Brush away all fat and blood, then rinse with clean water.

5. Disinfect with CHEMGENE HLD4H. Mix per the label, spray or wipe all cleaned surfaces and leave for the contact time. For direct food-contact surfaces, follow the label on whether a clean-water rinse is needed. Never mix with bleach or other chemicals.

6. Dry and set up again. Use fans or let the stall dry fully, stand boards and trays to drain, and do not lay out fresh stock until surfaces are dry. Keep goods off the floor.

7. Clean your hands and tools. Wash hands with soap and clean water after removing gloves, and clean boots, brushes and buckets before receiving new stock.

Guide by Stall Type

Pork, chicken and beef: the riskiest items are boards, knives, hooks, meat trays and scales. Remove all grease with hot water or dish soap, then disinfect per the label. Stainless hooks and rails can be treated without corrosion worries, per the product information. Don't forget the floor under the stall, where blood and wash water drip daily.

Fish and seafood: ice boxes, basins and tanks are usually plastic or fibreglass. Pour out old water, scrub off slime and scales, then wash and disinfect inside and out. Any ice kept through the flood must be discarded.

Vegetables and fruit: produce that touched floodwater should be thrown out, not washed and resold. Wash and disinfect plastic baskets and shelves and replace soaked display cloths.

Ready-cooked food: wash then disinfect pots, pans, ladles, trays and glass display cabinets, following the label on rinsing for food-contact items. Have submerged gas cylinders and hoses checked by a professional before use.

Dry goods, rice and spices: stock exposed to water or high humidity should be discarded because of mould risk. Wash wooden shelves, dry them fully, disinfect, and recheck for mould in the following weeks.

Shared market areas: public toilets, hand basins, stair rails, doors, trolleys and cashier points are shared touch points that management should wash and disinfect before reopening and regularly afterwards.

Before and After: A Market Stall After the Flood

Example Case, Continued: Auntie Juk Reopens with Confidence

Illustrative scenario to explain the steps, not a real customer review.

Instead of reopening the moment the water went down, Auntie Juk took one extra day. In the morning she threw out the leftover pork and the swollen wooden board, shovelled mud from under the stall and cleared the gutter. In the afternoon she scrubbed the stainless table, hooks, trays and ice box with detergent and rinsed them.

That evening she mixed CHEMGENE HLD4H at the label dilution, sprayed the table, hooks, trays, ice box, the outside of the scale and the floor beneath, left it for the contact time, followed the label for surfaces that touch meat directly, and let everything dry overnight.

The next morning she set out a new board, took delivery of fresh pork and put up a small sign saying the stall had been cleaned and disinfected. Her regulars came back, there was no chlorine smell, and the steel still shone. While water lingered around the market, she disinfected the stall after closing each day.

Reopening Checklist for Rangsit Market and Pathum Thani Fresh-Market Vendors

• ☐ Follow market management and local authority notices on when it is safe to reopen
• ☐ Have stall wiring checked before plugging in fridges and equipment
• ☐ Discard food, ingredients, ice and packaging that touched floodwater
• ☐ Replace wooden boards, sponges, cloths and tarps soaked in dirty water
• ☐ Shovel mud and clear the gutter in front of the stall
• ☐ Wash every surface with detergent and clean water until free of grease and mud
• ☐ Disinfect cleaned surfaces with CHEMGENE HLD4H at the label dilution and contact time
• ☐ For direct food-contact surfaces, follow the label on rinsing
• ☐ Let everything dry fully before laying out stock
• ☐ Use clean, safe water to wash food, never floodwater
• ☐ Wash hands often and provide hand gel or a basin for customers
• ☐ Watch for fever, calf pain, red eyes or diarrhoea; see a doctor and mention flood exposure

Advice for Shoppers When Rangsit-Area Markets Reopen

Customers play a part too. In the first days after a market reopens, choose stalls that look freshly cleaned and dry, with goods raised off the floor and no standing water underneath. Avoid buying produce that looks muddy or water-stained, and be wary of ice or chilled seafood if you are unsure how it was stored during the flood. Wear closed shoes if the market floor or the road outside is still wet, and wash your hands with soap after shopping, before handling food at home.

In your own kitchen, keep raw meat and seafood separate from ready-to-eat food, use different boards for each, and cook meat, poultry and eggs thoroughly. Wash and disinfect your shopping baskets and reusable bags if they touched floodwater on the way home. If anyone in the family develops diarrhoea, vomiting or a fever after eating, keep them hydrated and see a doctor, particularly for young children, older relatives and pregnant women. Good habits on both sides of the counter are what bring a community market back to normal quickly and safely.

Frequently Asked Questions

1. Can I wash flood-touched vegetables and still sell them?

Not recommended. Food that touched floodwater should be discarded, because it may carry sewage and germs that washing cannot reliably remove.

2. Can I spray CHEMGENE HLD4H directly on meat or vegetables?

No. It is for surfaces and equipment, not for applying to food.

3. Do I have to wash the table before spraying?

Yes, every time. Mud, grease and blood reduce disinfection. Wash with detergent and clean water first, then apply per the label.

4. Is it safe on stainless tables and meat hooks?

Yes. Per the product information it is non-corrosive to stainless steel, aluminium, rubber, plastic and fibreglass.

5. What dilution should a food stall use?

The product information lists 1:30, 1:50, 1:60, 1:100 and up to 1:200. Follow the label for the job, or ask the team by phone or LINE.

6. Is one disinfection enough?

Do one thorough round before reopening, then keep cleaning and disinfecting after closing each day, especially while water still stands nearby.

7. I waded for days and now have a fever and calf pain. What should I do?

See a doctor promptly and mention flood exposure, as this may signal leptospirosis. Disinfectant is not medical treatment.

Reopen Your Stall with Surfaces Customers Can Trust

Wash off every trace, then disinfect with a medical-grade product that won't corrode your stainless steel.
