Set the household target before shopping
A 72-hour plan is twelve person-days of food for four people. An illustrative 2,000-calorie daily target yields 24,000 calories, but a child's portion, a very active adult, or a medical diet may call for a different mix. Use package nutrition panels to add actual calories rather than counting a pouch, can, or serving as one complete meal.
FoodSafety.gov recommends at least a three-day supply of foods with a long storage life that require little or no cooking, water, or refrigeration. Store foods that fit the people and pets in your household, including allergies and special diets.
- 12 person-days for a family of four
- Count the calories in the exact products you buy
- Plan for infant, allergy, medication, texture, and pet needs separately

Use this as a starting basket, then swap brands and flavors for foods your family already eats. The quantities are examples, not a guaranteed calorie total; compare labels and use the food calculator to close any gap.
- 12 to 24 complete ready-to-eat meal portions, depending on their actual calories and the rest of the basket
- 12 to 18 cans of familiar meals, beans, fish, vegetables, or fruit with enough protein and calories across the mix
- Nut or seed butter, crackers, tortillas, oats that can be eaten cold, dried fruit, and shelf-stable snacks
- Shelf-stable milk or a suitable alternative, plus infant food or formula if needed
- A tested manual can opener, utensils, wipes, and food-safe bags for waste
A sturdy manual opener makes shelf-stable canned meals practical without electricity.
Check on AmazonBuild three days of real meals
One workable pattern is shelf-stable milk, fruit, and nut butter for breakfast; a ready-to-eat meal or bean-and-tortilla combination for lunch; and a canned entrée, fish, or another complete meal for dinner. Add calorie-dense snacks so the daily total matches the people eating it.
Choose cans with pull tabs when convenient, but do not rely on tabs alone. Keep a manual can opener in the same bin. All canned food can be eaten at room temperature if the product is labeled ready to eat and the package is intact; follow the directions on the exact product.
Keep water beside the food
FoodSafety.gov advises at least one gallon of water per person and per pet per day, with more for heat, illness, pregnancy, and other needs. Four people over three days need at least twelve gallons as a baseline. Dry meals, beverage mixes, and cleanup increase the total, so favor no-cook foods that do not consume the drinking supply.
Store containers where you can lift and move them safely, follow the container maker's sanitation and rotation instructions, and use the water calculator for household and pet adjustments.

Put the food, opener, water, a printed inventory, and dietary instructions where everyone can find them. Store the reserve in a cool, dry interior location, away from chemicals and flood risk. Twice a year, check package dates and seals and move suitable older food into ordinary meals.
Discard bulging, opened, leaking, or damaged cans and pouches. Do not taste questionable food to decide whether it is safe.
Frequently asked questions
How much emergency food does a family of four need for three days?
Plan twelve person-days of food. A sample 2,000-calorie daily target totals 24,000 calories, but adjust for the actual household and check package labels.
Do I need MREs for a 72-hour kit?
No. MREs are a convenient ready-to-eat option; familiar shelf-stable grocery foods can cover much of the reserve if calories, nutrition, water, and opening tools are accounted for.
How much water goes with the food?
Start with at least one gallon per person per day: twelve gallons for four people over three days. Add more for pets, heat, health needs, and preparation.
