Key takeaways

• Store a several-day supply of non-perishable food your household will eat, with a manual can opener (Ready.gov).

Storms, outages and water advisories can cut off power and clean tap water for days. A small stock of water and non-perishable food is one of the cheapest forms of insurance, and it can be built a little at a time on a tight budget. This guide summarizes advice from Ready.gov (FEMA), the CDC and FoodSafety.gov, and lists popular, widely reviewed storage items on Amazon. For older adults, also plan for medicines, special diets and anything that needs electricity.

1. Water: How Much to Store

Ready.gov says to store at least one gallon of water per person per day for several days, for drinking and sanitation. A normally active person needs about three quarters of a gallon of fluid daily from water and other beverages, but individual needs vary with age, health, activity, diet and climate. Children, nursing mothers and sick people may need more, a medical emergency might require additional water, and in very hot temperatures water needs can double.

The CDC says to store at least 1 gallon of water per person, per day for 3 days, for drinking, cooking, brushing teeth and other uses, and to try to store a 2-week supply if possible. It suggests storing more for pregnant women, people who are sick, pets, or if you live in a hot climate.

2. Choosing and Storing Water

• The CDC says unopened, commercially bottled water is the safest and most reliable source of water in an emergency. Store it in the sealed original container in a cool, dark place, and observe the expiration date (CDC, Ready.gov).
• If you fill containers yourself, the CDC says it is best to use FDA-approved food-grade water storage containers, which can be found at surplus or camping supply stores. Contact the manufacturer if you are not sure whether a container is food-grade.
• Clean the containers before use as the CDC and Ready.gov describe, and replace water you stored yourself every 6 months.
• The CDC suggests storing a bottle of unscented liquid household chlorine bleach to disinfect water if necessary. Follow the CDC’s “Making Water Safe in an Emergency” instructions.

3. Food: Several Days of Non-Perishables

Ready.gov says to store at least a several-day supply of non-perishable food, choose foods your family will eat, and remember any special dietary needs. After a disaster there may be outages lasting several days, so stock canned foods, dry mixes and other staples that do not require refrigeration, cooking, water or special preparation, and be sure to include a manual can opener and eating utensils.

Ready.gov’s suggested items include ready-to-eat canned meats, fruits and vegetables, protein or fruit bars, dry cereal or granola, peanut butter, dried fruit, canned juices, non-perishable pasteurized milk, high-energy foods and comfort or stress foods. Check labels for sodium and for any dietary restrictions, and ask your doctor or dietitian if you have a condition such as diabetes or kidney disease.

4. Food Safety Without Power

• Keep refrigerator and freezer doors closed. The refrigerator keeps food cold for about four hours if unopened (Ready.gov).
• Use a refrigerator thermometer to check the temperature, and keep food at 40°F or below (Ready.gov).
• Discard perishable food such as meat, poultry, fish, eggs or leftovers that have been above 40°F for two hours or more (Ready.gov).
• Do not eat foods from cans that are swollen, dented or corroded, and remember “when in doubt, throw it out” (Ready.gov).
• Charcoal grills and camp stoves are for outdoor use only (Ready.gov).

6. Build It Slowly on a Budget

• Add a few extra cans or a gallon of water to each shopping trip.
• Rotate: use the oldest items first and replace them, and write dates on containers.
• Store everything in one easy-to-reach place, and make sure you can lift heavy containers. If you cannot, use smaller bottles.
• Include your medicines and plan for ones that need refrigeration, as Ready.gov and your provider advise.
