Canning for Emergencies:
A Practical Guide
Canning is a time-tested, powerful way to create a resilient and nutritious emergency food and water supply. When done safely, it lets you fill your pantry with shelf-stable meals, fruits, vegetables, and even sterile water—ready for storms, blackouts, or supply disruptions.
Why Canning is Smart for Emergency Prep
Long Shelf Life: Properly canned foods and water last years—often up to a decade—without refrigeration.
Nutrition Preserved: Canning retains much of a food’s nutrition, so you can eat well even in an emergency.
Customizable: Choose ingredients tailored to your family’s dietary needs, tastes, and traditions.
Less Waste: Preserve seasonal harvests and pantry surpluses while reducing reliance on fragile supply chains.
Staples to Can for Emergency Pantry
Food Type | Why It Matters | Storage Life |
Low-Acid Veggies | Corn, green beans, peas, carrots—fiber/vitamins | 2–5 years |
Protein-Rich Meats | Chicken, beef, ham, fish—adds vital nutrients | 2–5 years |
Ready Meals | Chili, stews, soups—heat & eat | 2–5 years |
Fruit & Tomatoes | Fiber, vitamin C, variety, comfort | 1–2 years |
Water (see below) | Essential for hydration/sanitation | Decades |
Pro tip: Also include staples like canned beans and lentils for quick, satisfying protein.
How to Safely Can Food for Emergencies
Choose the Right Method
Water Bath Canning: For high-acid foods (jams, most fruits, pickles, tomatoes with added acid).
Pressure Canning: For low-acid foods (vegetables, meats, poultry, fish) to prevent botulism.
Start with Research-Tested Recipes
Only use university extension or USDA/National Center for Home Food Preservation guidelines.
Avoid unverified online or hand-me-down recipes to prevent foodborne illness.
Sanitize and Prepare Jars and Lids
Clean thoroughly and inspect for chips/cracks.
Follow correct “headspace” for safe sealing.
Process for the Correct Time and Pressure
Adjust processing times for your altitude.
Never shortcut the canning or cooling process.
Label, Store, and Rotate
Write date and contents on each jar.
Store in a cool, dark, dry place, ideally 50–70°F.
Use oldest jars first; replenish as you go.
Canning Water for Disaster Recovery
Canning water ensures you have a supply that remains shelf-stable for decades—longer than bottled water!
Steps:
Use potable, clean water only.
Boil water for 5 minutes.
Fill sterilized canning jars, leaving ½-inch headspace.
Process in a boiling water canner (check canning times per jar size).
Cool, check for seals, remove rings.
Store in a cool, dark location.
Key Cautions:
Canning does NOT remove heavy metals, chemicals, or other contaminants—filter and disinfect any non-municipal water before canning.
Use only jars that seal properly. Unsealed jars must be used right away.
Quick Emergency Canning Safety Tips
Never can low-acid foods (meats, most vegetables) in a water bath—pressure can only.
Don’t improvise processing times or methods.
When in doubt, throw it out—don’t risk botulism.
Stack jars no more than two-high to protect seals during storage.
Keep emergency canning equipment accessible: pressure canner, water bath canner, good supply of jars, lids, and bands.
Canned Goods to Stock for Emergencies
Protein: Chicken, tuna, salmon, chili, beans, lentils, stew.
Veggies: Potatoes, corn, carrots, green beans, tomatoes.
Fruits: Peaches, pears, applesauce, pineapple.
Convenience Items: Soups, pasta sauces, evaporated milk, coconut milk.
Storage and Maintenance
Store canned goods with other emergency supplies.
Rotate stock—use and replace within recommended shelf-life.
Regularly check seals and appearance.
