FIELD NOTE 04 / Stay safe / First 72 hours
The pantry is now a department
Use a supply ledger, protect the cold chain, and avoid turning a power outage into food poisoning.
Your objective
Make a safe meal plan from food you actually have, with allergies and cooking needs recorded.
Gather these
- Shelf-stable food your household eats
- Manual can opener
- Appliance thermometer
- Safe drinking water
- Paper inventory
The procedure
Record the outage
Write when power was lost and keep refrigerator and freezer doors closed. With doors closed, CDC gives up to four hours for a refrigerator, 48 hours for a full freezer, and 24 hours for a half-full freezer. These are conditional estimates, not a guarantee after repeated opening.
Check food safety
Keep refrigerated food at 40°F (4°C) or below. Discard refrigerated perishables after four hours without power or another cold source. That closed-fridge estimate does not permit keeping food warm: discard affected perishables, such as meat, eggs, milk and leftovers, held at or above 40°F (4°C) for more than two hours. Discard them if their safe time and temperature history cannot be established. Consult the linked FoodSafety.gov charts for food-specific decisions, including thawed frozen food; ice crystals or a temperature at or below 40°F may permit refreezing, but there are exceptions. Never taste food to test safety.
Choose simple meals
List shelf-stable foods, portions available, allergies, and water or fuel needed. Start with meals requiring little preparation. Keep a separate list for infant feeding and clinical diets so the general meal plan does not silently exclude someone.
Keep a fair ledger
Use columns for item, quantity, storage location, date, and planned use. Record incoming supplies and actual use. Agree how to prioritize people with additional needs and how to ask privately for help. Recheck the inventory before promising meals.
Preserve only with tested methods
Home canning needs a tested recipe and the specified equipment, process, and altitude adjustment. Low-acid foods require appropriate pressure canning. A sealed lid alone does not prove safety. Save an approved reference before a disruption and practice under competent guidance.
Stop and get help when…
- Discard affected perishable food when its safe time and temperature history cannot be established. For food exposed to floodwater, use official disposal guidance; do not taste it to check safety.
- Do not improvise canning recipes, shorten processing, or replace a pressure canner with an unspecified appliance.
A small, safe practice run
Plan one ordinary shelf-stable meal without electricity. Include safe water, allergies, and an accessible opening method. Do not disable your fridge to practice.
