How to Plan for a Food Shortage: Stock, Preserve and Grow Safely

This post may contain affiliate links, full disclosure here.

Quick answer: prepare for a food shortage by learning your local risks, building a pantry of foods you eat, storing water, and learning safe preservation. Store enough shelf-stable food for at least two weeks and work toward more, rotate it, and plan meals around it. Preserve food only by tested methods, since improper home canning can cause botulism. A small garden can help, but it is a supplement, not a substitute for a pantry.

Food shortages range from empty shelves for a few days after a storm to price spikes and supply problems that last weeks or months. Most are local and temporary. The best defenses are a well-organized pantry, a plan for water and cooking and a few practical skills. This guide covers risks, stocking, safe preservation and growing food. For the numbers behind food storage, see the USDA and extension links we cite.

Identify your local risks

Think about what could disrupt food supply where you live: hurricanes, floods, winter storms, wildfires, earthquakes, power outages, transport disruptions or economic stress. Ready.gov and your local emergency management office list common hazards for your area. Also think about your household: your income stability, health needs, number of children and distance from grocery stores.

Build a food reserve

A food reserve is a rotating stock of shelf-stable food you eat. Start with a three-day supply, build toward two weeks and keep growing if you have space and budget. Choose canned goods, dry staples, nut butters, shelf-stable milk, dried fruit and comfort foods. See our guides to how much food to stock, starting a 3 month food supply and prepper foods.

Water first

Water is more urgent than food. Store at least one gallon per person per day, and learn how to make water safe. See our guide to storing water and purifying water.

Fresh foods and the freezer

Fresh food will run out first. Eat perishable items early in an outage, and use the freezer wisely. Ready.gov notes a full freezer holds temperature about 48 hours with the door closed, and discard food held above 40 F for two hours or more. Freezing extra meat or bread when it is on sale can stretch your budget, but frozen food depends on power, so do not make it your only reserve.

Tools and equipment

Manual can opener and a spare
Camp stove and fuel for outdoor use, pots, utensils and a lighter
Coolers and ice or ice packs
Food-safe storage containers, such as sealed bins and jars
A thermometer for the fridge and freezer
Water storage containers and treatment supplies

Skills that help

Learn to cook from scratch with simple ingredients, to plan meals from your pantry, to preserve food safely, to garden on a small scale and to track what you have. A little practice before a shortage is worth much more than a lot of gear.

Create a food shortage plan

Write down how many people and pets you need to feed.
Decide how many days of food you want to cover.
List the meals you will cook from your pantry.
Check what you have and mark what you need.
Make a shopping plan with a weekly budget.
Store water and a way to cook without power.
Review and rotate twice a year.

What should I buy?

Buy foods you already like and that keep: rice, pasta, oats, dried beans, canned vegetables, fruit, tuna, chicken, soup, peanut butter, shelf-stable milk, flour, sugar, salt, spices and cooking oil. Consider calories as well as variety. Buy what you will use, store it properly and rotate. The USDA says canned low-acid foods keep two to five years, and high-acid foods 12 to 18 months.

Preserving food safely

Preserving food at home can stretch your supply, but safety comes first. The National Center for Home Food Preservation provides tested methods and recipes. Key points:

Canning low-acid foods such as vegetables, meat and poultry must be done in a pressure canner using a tested recipe. Improper canning can cause botulism, a rare but serious illness.
Boiling-water canning is only for high-acid foods, such as many fruits, pickles and jams, using tested recipes.

Freezing is simple and safe if your freezer stays at 0 F or below, but it depends on power.
Drying and dehydrating work well for fruit, herbs and some vegetables. Home-dried fruit keeps about a year at 60 F and vegetables about half as long, per the NCHFP.
Never use untested recipes, old methods or open-kettle canning. Discard any jar with bulging lids, leaking, spurting or off smells, and do not taste it.

See our guides to dehydrated food, home canned food and dehydration techniques.

Start a small garden

A garden can add fresh vegetables and herbs, but it takes time to produce and is a supplement to stored food. Start small with easy crops suited to your climate, and use your local cooperative extension office for planting dates and advice. Choose a sunny spot, good soil and a reliable water source. Containers and indoor setups with grow lights can work in small spaces. Learn what grows quickly: see our guide to veggies that grow quickly. Save seed only from non-hybrid varieties, and see our survival seed bank guide.

Fishing, hunting and livestock

These can supply food in some situations, but they require licenses, skill, land and time, and they are regulated by state and local law. They are not a substitute for a stocked pantry. If you plan to fish or hunt, learn the rules, seasons and safe handling practices first, and cook wild game and fish to safe temperatures.

Emergency items to grab

If you must leave, take water, a few days of food, a can opener, medications, baby supplies, pet food, cash and your documents. Our 72-hour kit checklist lists the essentials.

Look out for neighbors

Community networks matter. Check on older neighbors, share information and consider local food banks and community programs if you or others are in need. Do not hesitate to ask for help if you are struggling to afford food.

Frequently Asked Questions

How much food should I store for a shortage?

Start with a few days, build to two weeks and add more as you can. Rotate it so it does not go to waste.

What foods last the longest?

Dry staples such as rice and beans, canned goods and commercially packaged freeze-dried food keep well when stored cool and dry. Check dates and condition regularly.

Is home canning safe?

Yes, if you use tested recipes and the right method. Low-acid foods need a pressure canner. Improper canning can cause botulism.

Can a garden replace stored food?

Not quickly. A garden supplements your pantry but takes time to produce.

What if I cannot afford a lot of food?

Start small, buy a few extra items each trip and use local food banks and community resources if you need help.

Bottom line

A reserve of food you eat, a water plan and a few safe preservation skills will cover most shortages. Build slowly, rotate, follow tested food-safety methods and look out for your neighbors.
