Preparation Steps

  • Start with a 3-day supply and expand to 30 days, then to 90 days over time — do not try to build everything at once.
  • Store food in a cool, dark, dry location; temperatures below 21°C (70°F) significantly extend the shelf life of most staples.
  • Use airtight food-grade buckets or sealed mylar bags with oxygen absorbers for bulk long-term storage of grains and legumes.
  • Label every container with the purchase date and estimated use-by date.
  • Rotate your stock consistently using FIFO (First In, First Out) — older items are consumed first and replaced with fresh stock.

Immediate Actions

  • Calculate your household's caloric needs: 1800–2400 calories per adult per day; adjust for children, pregnant women, and those doing physical labor.
  • Focus on calorie-dense, shelf-stable foods: white rice, dried beans, rolled oats, lentils, pasta, peanut butter, canned fish, canned legumes, and cooking oil.
  • Include vitamins in your supply — particularly Vitamin B12, C, and D, which are commonly deficient during emergency diets relying on shelf-stable foods.
  • Store water separately at a minimum of 1 gallon (approximately 4 liters) per person per day for at least 3 days; scale up as space allows.
  • Include comfort and morale foods: coffee, tea, sugar, chocolate, and familiar snacks matter during prolonged stressful situations.

What to Avoid

  • Do not store only one or two types of food — nutritional monotony leads to vitamin and mineral deficiencies over time and severely impacts morale.
  • Do not forget to store foods you actually know how to cook — a bag of dried kidney beans is useless if you don't know they must be soaked and boiled to remove toxins.
  • Avoid storing food in areas with temperature fluctuations — a garage that reaches 35°C (95°F) in summer drastically reduces food shelf life.
  • Do not neglect comfort and specialty items for household members with dietary restrictions, allergies, or medical conditions.

Supplies Needed

  • Food-grade airtight buckets with gamma-seal lids.
  • Mylar bags and oxygen absorbers for long-term bulk grain storage.
  • Manual hand-operated can opener.
  • Camping stove and adequate fuel supply for cooking without electricity.
  • Food thermometer for verifying safe cooking temperatures.

Recovery Steps

  • Rotate stock regularly and consistently — check expiry dates every 6 months and consume or donate items approaching their end date.
  • Replenish all consumed stores as soon as supply chains are accessible again after an event.
  • Adjust your quantities and food variety based on what your household actually needed and used during the emergency.
  • Evaluate storage conditions and address any issues with moisture, pests, or temperature extremes.
  • Update your written inventory after every rotation or restocking event.
