After the Flood: Which Stockpile Supplies to Keep, Clean, or Throw Away

You did everything right before the typhoon. The rice was stored, the canned goods were lined up, the water containers were full, the first aid kit was ready. Then the floodwater came in—maybe ankle-deep, maybe up to the second step of the stairs—and sat there for a night or two.

Now the water is gone, and you are looking at a shelf of supplies that were supposed to keep your family going. The big question is simple: what can you still use, and what has to go?

This is a question I have seen families struggle with many times after flooding. Throwing away food feels wasteful, especially when money is tight and the sari-sari store down the street is also flooded. But keeping the wrong items can turn a property problem into a health problem, right when clinics are busiest. This guide walks through each type of supply, one category at a time, so you can sort with a clear head.

Start With One Rule: Floodwater Is Not “Just Water”

Floodwater in Philippine towns and cities rarely stays clean. As it moves through streets, it can pick up sewage from overflowing canals and septic tanks, animal waste, fuel and oil from vehicles, garbage, and chemicals from homes and small shops. You cannot tell by looking at it. Even water that looks clear can carry germs.

So the sorting rule is this: anything that floodwater touched should be treated as contaminated until proven otherwise. The question is not “does it look okay?” but “can this item be cleaned safely, all the way through?”

For many items, the answer is no, because floodwater seeps into places you cannot reach: inside a rice sack, under a bottle cap, through the paper of a medicine box. For a smaller group of items, the answer is yes, if you clean them properly.

Before You Sort: Protect Yourself

Sorting flood-damaged supplies is part of cleanup, and cleanup is when many injuries and infections happen. Before you start:

• Wear boots and gloves. Rubber boots and household rubber gloves are enough for most sorting work.
• Cover any wounds. Leptospirosis is a known risk after floods in the Philippines, and it can enter through cuts and scratches on the skin. If you have an open wound, keep it dry and covered, or let someone else handle the wet items. (For wound care when clinics are hard to reach, see First Aid When Help Is Delayed.)
• Prepare clean water and soap. You will need it for washing your hands and for cleaning the items you decide to keep.
• Set up three areas: a “keep” area that stays dry, a “clean first” area, and a “discard” area. Label them with a marker on cardboard so family members helping you do not mix them up.

Food: What to Throw Away, What You Can Save

Throw away

• Rice, flour, sugar, and grains in sacks, plastic bags, or open containers that were wet. Water soaks through woven sacks and thin plastic. Drying it in the sun does not remove contamination.
• Noodles, biscuits, chips, and snacks in plastic or paper packaging. The packaging is not designed to keep out water under pressure.
• Anything in jars or bottles with screw tops, snap lids, or crown caps—including sauces, peanut butter, condiments, bagoong, and jams. Floodwater can get under the lid.
• Coffee, milk powder, and cereals in boxes, sachets, or cans with pull-up plastic lids.
• Fresh food—fruit, vegetables, eggs, meat, fish—that floodwater touched.
• Food from the refrigerator or freezer if it was flooded, or if the power was out long enough that frozen items fully thawed and stayed warm.
• Cans that are dented, swollen, rusted, or leaking, or cans whose seams are damaged.

Can be saved after cleaning

• Commercially sealed all-metal cans (sardines, corned beef, meat loaf, vegetables) that are not damaged in any way.
• Commercially sealed retort pouches (the thick foil-like pouches some ready-to-eat meals come in) that are intact and not punctured.

To clean them: remove the paper labels (floodwater soaks into paper), wash the can or pouch with soap and clean water, then sanitize it by soaking in a diluted household bleach solution prepared according to the bleach product’s label or DOH guidance, and let it air-dry. Write the contents and expiry date on the can with a permanent marker before you peel the label off, or you will be guessing later.

When you finally open a cleaned can, wash the top again just before opening, and use a clean can opener.

Drinking Water: Be Stricter Than You Think

This is where many families take risks, because water feels like the most important thing to keep.

• Bottled water that floodwater touched: do not drink it. Floodwater can enter around the cap and the neck of the bottle, even if the seal looks fine.
• Water containers (jugs, drums, pails) that were submerged: discard the water inside. The container itself can usually be cleaned and sanitized, then refilled from a safe source.
• Water containers that stayed above the flood line: generally safe if they were covered and nothing splashed in. Wipe the outside before opening.
• Tap water after a flood: follow announcements from your local government and water provider. Do not assume it is safe just because it is flowing again.

If you are unsure about any water, use your safest source for drinking, cooking, brushing teeth, and preparing baby formula. Use the doubtful water only for flushing toilets or cleaning floors.

Medicines and First Aid Supplies

Medicines are a hard loss, especially maintenance medicines for blood pressure, diabetes, or asthma. But medicines that got wet cannot be trusted.

• Tablets, capsules, syrups, and creams that floodwater touched should be discarded, even if they are inside blister packs. Water and germs can enter through damaged foil, and moisture can damage the medicine itself.
• Insulin and other medicines that were in a refrigerator during a long power outage may have lost effectiveness. Ask a pharmacist or your doctor before using them.
• Bandages, gauze, cotton, and plaster that got wet are no longer sterile. Replace them.
• Thermometers, scissors, and tweezers made of metal or hard plastic can be washed and disinfected.

Before you throw medicines away, take a photo of every label: name, dosage, and prescription details. This makes it much faster to get replacements from your health center, barangay health station, or pharmacy. If you have a maintenance medicine and cannot get a refill, tell your barangay health worker or the medical team at an evacuation center right away. Do not wait until you run out.

Batteries, Power Banks, and Electrical Items

This is a fire safety issue, not only a cleanliness issue.

• Power banks, rechargeable lamps, and lithium batteries that were submerged should not be charged or used. Water can damage the internal parts and cause overheating, swelling, or fire—sometimes days later. Put them in a dry metal container or a safe area away from things that burn, and dispose of them properly when collection becomes available.
• Disposable batteries (AA, AAA, D) that got wet may leak or corrode. Replace them.
• Flashlights and radios that were soaked: remove the batteries, let the device dry fully, and do not assume it works. Test it in daylight before you rely on it at night.
• Extension cords and appliances that were submerged should be checked by a qualified electrician before use.

In my experience, fires after floods often start from electrical items that people turn back on too early. A dead flashlight is a small loss. A charging power bank that catches fire in a house full of wet clutter is a much bigger one.

Clothes, Blankets, Documents, and Your Go Bag

• Clothes and blankets: can usually be saved. Wash them in hot water with detergent, and dry them completely in the sun. Anything that still smells of mold after washing should be discarded, especially items for babies or family members with asthma.
• Mattresses, pillows, and foam: usually cannot be cleaned properly once soaked with floodwater.
• Important documents: do not throw them away. Separate the pages carefully, lay them flat to dry out of direct sunlight, and photograph them. Many government offices can reissue documents, and a damaged original or photo will help.
• Your go bag: if it was flooded, empty it completely and apply all the rules above to each item. Then rebuild it. For a practical list, see Go Bag para sa Pamilyang Apat.

Judgment Points

When you are tired and surrounded by wet boxes, it helps to have a short set of questions. For each item, ask:

1. Did floodwater actually touch it? If it was on a high shelf and stayed dry, it is probably fine. Do not throw away good supplies out of panic.
2. Is it sealed in metal or a thick retort pouch, with no damage? If yes, clean and keep. If it is paper, plastic, cloth, or has a screw-top lid, discard it.
3. Will someone swallow it, put it on a wound, or charge it? For these three uses, be strict. When in doubt, throw it out.
4. Who will use it? Be even more careful with food, water, and medicine for babies, older adults, pregnant women, and anyone with a chronic illness.

What You Can Do Today

Even if your home has not flooded this season, a few small changes will make the next sorting job much easier:

• Raise your stockpile. Move supplies to a higher shelf or the second floor if you have one. Even 60 centimeters off the floor makes a difference in many floods.
• Use sealed plastic boxes with tight lids for rice, noodles, and snacks. They are not perfect, but they give you more time.
• Keep a list of your medicines on your phone, with photos of the labels and prescriptions.
• Store power banks and batteries high and dry, separate from food.
• Write expiry dates on canned goods with a marker now, so you are ready if labels ever need to come off.

If the flood also cut your power, cooking with the supplies you saved brings its own risks. See Safe Cooking During a Brownout before lighting LPG or charcoal indoors.

Summary

After a flood, your stockpile is not “all lost” and not “all fine.” Most items fall into clear groups. Food in paper, plastic, sacks, and screw-top jars goes. Undamaged, commercially sealed metal cans and retort pouches can be cleaned and kept. Bottled water and medicines that floodwater touched should be replaced. Soaked batteries and power banks should never be charged. Clothes and documents can usually be saved with care.

Sorting this way is not about being wasteful. It is about making sure the supplies you prepared to protect your family do not end up making someone sick. The time to rebuild your stockpile is after you have sorted—and this time, a little higher off the floor.
