Managing food after power loss
Which food to use first, preserve or discard when refrigeration stops.
Critical caution: Smell and appearance cannot prove that food is safe. Never taste-test suspect food.
- Time
- Immediate–48 hours
- Difficulty
- Low
- Outcome
- Use safe perishables without wasting cold air or risking illness
Survival lens: A disciplined inventory protects both nutrition and morale. Use the most time-sensitive resources first, but never turn scarcity into a reason to eat unsafe food.
Before you begin
- Record the time power failed
- Keep appliance doors closed
- Separate flood-exposed food
What you need
- Fridge/freezer thermometers
- Cooler and ice packs
- Permanent marker
- Waste bags
Step-by-step procedure
- Preserve the cold. Keep doors shut. An unopened refrigerator keeps food cold for about four hours; CDC notes about 48 hours for a full freezer and 24 hours for a half-full freezer.
- Measure, do not guess. Use appliance and food thermometers where available. Do not rely on room temperature, smell or appearance.
- Move high-risk food once. After four hours, transfer refrigerated perishables to a cooler only if ice can keep them at 4°C/40°F or below.
- Prioritise meals. Use safely cold refrigerated food, then partially thawed frozen food that still has ice crystals, then shelf-stable food.
- Discard decisively. Throw out perishable refrigerated food above safe temperature for too long and anything touched by floodwater. Never taste-test.
- Clean and record. Bag waste securely, clean contaminated surfaces and note what remains for meal planning.
How to check it is working
- Temperature or time history is known
- Raw and ready-to-eat foods are separated
- No food touched floodwater
- Discard decisions are recorded once—not repeatedly debated
Common mistakes
- Opening doors to “check” repeatedly
- Eating food because it smells normal
- Refreezing food without temperature evidence
- Saving questionable food for animals
