What these facts tell us is that this flood spread across most of the province and hit people whose lives are tied directly to the land. With paddies, ponds and orchards under water, the economic loss is already heavy. If people in the household fall ill while they are racing to rescue their fields, the burden on the family multiplies.

How a Farmland Flood in Prachinburi Differs from an Urban Flood

Water that flows through rice fields, shrimp ponds, orchards and animal pens carries a different load from urban floodwater. It typically brings silt, plant debris, dead animals, animal manure and traces of farm inputs. Overflowing shrimp ponds can release water that is high in organic matter. In fields and orchards, rodents that normally live along paddy dykes and in sheds flee to higher ground, which is very often someone's house.

Many farm homes in Prachinburi are raised on stilts or are single-storey houses close to the fields, with the tractor, water pump, sprayer tanks, fertiliser sacks and other equipment kept nearby. In a flood, all of this sits in the same water that flows through the house. Germs from the fields can then travel into kitchens and bedrooms on hands, boots and shared tools.

There is also the question of what is stored where. Fertiliser sacks, fuel cans for the pump and farm chemicals are often kept in the same space under the house as rice and household items. When floodwater moves them around, containers can split or tip over, and residues spread across the floor. That is one more reason to wear gloves, to separate damaged chemical containers from household goods straight away, and to wash every surface thoroughly before any disinfectant goes on. It is also a reason never to mix cleaning products, because you cannot always be sure what is already on a surface after a farmland flood.

Farmers also rarely get a break. As soon as the water drops, many go straight out to check the damage, save what they can and prepare for the next crop. House cleaning gets put off or rushed, and that is exactly when mold and bacteria get the upper hand.

Germs Prachinburi Farming Families Should Watch for After the Flood

This section draws on guidance from the World Health Organization (WHO), the US CDC and Thailand's Department of Disease Control.

Leptospirosis: a top risk for rice and orchard farmers

Thailand's Department of Disease Control regularly warns that farmers who wade, tread through mud or stand in paddy water for long periods are at risk of leptospirosis. The bacteria come from the urine of rats and some other animals, are present in water and mud, and enter the body through cuts, scrapes or skin softened by long soaking. Watch for a sudden high fever, headache, muscle pain (especially in the calves) and red eyes. Anyone with these symptoms after working the fields or wading must see a doctor promptly and mention the flood exposure. Effective prevention means rubber boots and gloves, covering wounds and washing immediately after leaving the water. A disinfectant reduces germs on surfaces in the home and on equipment, but it does not prevent or treat this disease.

Bacteria from manure and sewage: E. coli and Salmonella

Water that passes through animal pens, septic tanks and manure-covered ground can carry E. coli and Salmonella into the house. These bacteria remain on kitchen floors, kitchenware, water buckets and shared tools, causing diarrhoea, vomiting, stomach pain and fever. When the whole household is already exhausted from rescuing the fields, these illnesses can knock people down faster than usual.

Viruses spreading in homes and shelters

Norovirus and rotavirus cause diarrhoea and spread through hands, food and surfaces. RSV and influenza spread fast when people are crowded together, for example in temporary shelters or relatives' homes housing several families. Hand-foot-and-mouth disease among small children passes through shared toys and surfaces.

Mold in rice stores, wooden houses and damp sacks

Mold thrives on anything that has soaked up water: walls, wooden floors, rice stores, sacks, mats and mattresses. WHO and CDC recommend cleaning and drying within 24–48 hours of the water receding to limit mold growth. Spores can cause allergies, coughing, wheezing and eye irritation. Paddy rice or produce that was soaked and has gone moldy should not be eaten.

Who in a farming family is most at risk

• Farmers who work the fields, wade and tread through mud every day, especially those with wounds on their feet and legs
• Older family members at home, common in rural households
• Young children who play on the floor and with toys that may have been in the water
• Pregnant women and people with diabetes, kidney disease or weakened immunity
• Workers helping to rescue shrimp ponds and orchards, who are in water and mud for long hours

Example Case: A Farm House Beside the Paddies in Wang Dan

Note: this is an illustrative example case describing a situation commonly seen in farm homes after floods. It is not a real person or an interview from the news.

Imagine "Auntie Bua" and "Uncle Choet", who grow rice and have a small orchard in Wang Dan sub-district, Kabin Buri. Their home is a raised half-concrete, half-timber house. Underneath they keep a water pump, plastic sprayer tanks, hoes, spades and some sacks of paddy rice. Their son works at a factory in town and leaves his two children with them on weekdays.

As the water came in, they carried what they could upstairs, but the heavy tools and some of the rice sacks stayed below. During the flood, Uncle Choet waded out to check the paddies and orchard almost every day, while Auntie Bua cooked in a makeshift kitchen upstairs. The grandchildren were told not to play in the water, but kept sneaking off to sit on the stairs with their feet dangling in it.

When the water went down, they found thick mud under the house mixed with straw and a rotten smell from decaying plants. The sprayer tanks and pump were clogged with silt, the rice sacks had gone moldy, the lower wooden walls had black stains, and Uncle Choet had a graze on his shin from wading. Auntie Bua wanted to finish cleaning quickly with the bleach she had left, but worried it would eat into the pump and metal parts they still needed for work. This is the situation tens of thousands of farming households in Prachinburi are facing, and the plan below is written for them.

The first thing Auntie Bua should do is take Uncle Choet to a doctor to have the wound checked, mentioning that he has been wading for days. Then the cleaning can begin, step by step.

Why Soap or Bleach Alone Isn't Enough for a Farm Home

Washing with clean water and detergent is an essential first step, and CDC gives guidance on using diluted bleach properly. But for a home where living space and working equipment are mixed together, there are clear limits.

The Solution for Prachinburi Farm Homes: CHEMGENE HLD4H

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

• Organisms listed on the product page: bacteria, fungi, mycobacteria, Salmonella and viruses including influenza H1N1, RSV, norovirus, hand-foot-and-mouth virus and SARS-CoV-2.
• Speed: the product page states it kills within 1 minute, with 99.85% efficacy against COVID-19.
• Residual effect: surface protection for up to 14 days, per the product information.
• Dilution: 1:30, 1:50, 1:60, 1:100 and up to 1:200, chosen by task and label.
• Non-corrosive: stainless steel, aluminium, rubber, plastic and fibreglass.
• Biodegradable, and stated to be safe for people, pets and medical equipment when used as directed.
• Tests and approvals: Mahidol University, NHS England, ISO 9001:2015, ISO 13485, SGS, Intertek, CE, EN 13727 / EN 14348 / EN 13624 / EN 14476.

What matters most for farm homes is that it doesn't corrode aluminium, rubber or plastic, the main materials of sprayer tanks, hoses, pipes and boots, and that it dilutes as far as 1:200, so it can cover a large house and equipment shed without waste.

Because one diluted batch can cover the kitchen, bathroom, bedrooms, the space under the house and the equipment shed, a family can work through the whole property in a planned order rather than buying several different products for different jobs. That keeps costs down at a time when income from the fields has stopped.

Important caution: Chemgene HLD4H is a surface disinfectant for homes, sheds and equipment after cleaning. It is not for pouring into shrimp ponds, water bodies or paddy fields, or for spraying on crops. For restoring ponds and farmland, ask your local fisheries and agriculture officials for advice.

A Four-Week Recovery Plan for Farm Homes After the Water Drops

One principle runs through the whole plan: wash off the mud first, then disinfect per the label. Always wear rubber gloves, boots and a mask, keep air moving, and never mix Chemgene HLD4H with other chemicals, especially farm chemicals.

Week 1: Safety and the living space

• Switch off ground-floor power and have an electrician check it before use.
• Watch for snakes, centipedes and other animals that fled the water into the house and under it.
• Photograph damage to the house, fields, ponds and orchard for assistance claims.
• Throw away food, medicines and rice that touched floodwater.
• Shovel out mud and wash floors, walls, kitchen and bathroom with clean water and detergent.
• Dilute Chemgene HLD4H per the label, spray or wipe the washed surfaces, and leave for the label contact time.
• Start with the children's and older relatives' bedrooms, the kitchen and the bathroom.

Week 2: Under the house, sheds and working equipment

• Remove straw, moldy sacks and rotting debris.
• Wash the pump, sprayer tanks, hoses, hoes, spades and wheelbarrow free of mud.
• Disinfect handles, grips and high-touch surfaces with Chemgene HLD4H.
• Wash and disinfect boots, rubber gloves and raincoats after every day in the fields.
• Open sheds to sunlight and breeze to reduce humidity.

Week 3: Rice stores, water containers and shared touch points

• Clean the rice store and produce storage areas and make sure they are fully dry before new produce goes in.
• Wash water jars, buckets and tanks, then disinfect the outside and lids. Follow public health guidance on drinking and household water.
• Disinfect door knobs, stair rails, light switches, children's toys and the dining table regularly.

Week 4: Recheck and prevent a comeback

• Check for new mold on walls, behind cupboards and under wooden floors.
• Repeat disinfection on heavily used surfaces as advised on the label.
• If musty smells or chemical odours from repair work linger, consider an ozone odour and chemical-residue removal service.
• Keep an eye on everyone's health through the first month. Fever, calf pain, red eyes or severe diarrhoea means seeing a doctor promptly.

FAQ: Disinfecting After the Prachinburi Flood

Q: Can I use Chemgene HLD4H to disinfect a shrimp pond or paddy field?

A: No. It is a surface disinfectant for homes, buildings and equipment after cleaning, not for pouring into water bodies or aquaculture ponds, or spraying on crops. For pond and farmland recovery, consult fisheries and agriculture officials.

Q: Can I use it on a water pump and sprayer tank?

A: You can disinfect the outer surfaces and grips once the mud is washed off. According to the product information it doesn't corrode aluminium, stainless steel, rubber or plastic, but follow each machine's manual for cleaning internal parts.

Q: Can I spray it straight onto the mud under the house?

A: Not recommended. Shovel and wash the mud out first. Disinfectants work fully on clean surfaces, at the label dilution and contact time.

Q: We have grandparents and small grandchildren at home. Is it suitable?

A: The product page states it is safe for people and pets when used as directed, and it is used in elderly-care and childcare settings. Keep children out of the area while spraying, ventilate well and store the product out of reach.

Q: Does disinfectant protect farmers from leptospirosis?

A: Not directly. It reduces germs on surfaces at home and on equipment, but Leptospira infection comes from contact with water and mud through wounds or skin. Wear boots and gloves, cover wounds and see a doctor as soon as symptoms appear.

Q: Can I use it on boots every day after working in the fields?

A: Yes. Wash the mud off first, then spray or wipe with Chemgene HLD4H per the label. According to the product information it doesn't corrode rubber, so it suits regular repeated use.

Q: I'm in Prachinburi. How do I order?
