No.5 – Survival Food: Storage, Preservation, and Planning
When you prepare for emergencies, food is a top priority. Learn what to stock, how to store it, and its shelf life. Effective prepping means more than filling shelves—it’s about understanding preservation, knowing how storage times and food types differ when staying at home (stay-in-place) versus if you might need to evacuate quickly (bug-out), and adapting your plan for each scenario.
Why Survival Food Matters
During emergencies like storms, supply problems, power outages, or evacuations, you need food that provides enough calories and nutrition and will not spoil easily. Without a steady food supply, stress increases, and decision-making can suffer. Having a plan helps your family handle both short and long-term challenges with more confidence.
Now that we’ve discussed why survival food should be a priority, let’s transition to the practical side of planning: choosing the foundational types of survival food.
Types of Survival Food (and Why They Matter)
Survival foods fall into four main groups, each with unique benefits, storage needs, and shelf life.
1. Canned Foods: Reliable and Widely Available
Canned foods are dependable during emergencies. They are affordable, widely accessible, simple to rotate, and require no special equipment. Typical canned foods include soups, stews, beans, tomatoes, vegetables, meats such as corned beef and processed hams, fruits, and various milks and puddings, such as rice pudding.
Canned foods have a good shelf life, typically 2 to 5 years, but many remain safe to eat well past their ‘best by’ dates if the cans are sealed and undamaged. They are ideal for stocking up your stay-at-home larder if you have enough storage space, but heavy to carry if you have to bug out on foot.
2. Dry Staples (Rice, Beans, Pasta, Flour)
Dry foods are suited to long-term storage and provide cost-effective calories. Main types include white rice, pasta, oats, pulses (beans, lentils, peas), and flours.
They obviously need to be kept dry and are best stored in glass or heavy plastic airtight containers. Flimsy packaging, whether paper or light plastic, risks spoilage from vermin. The shelf life is good, and white rice, dry beans, and pasta can last decades if stored correctly. These foods are best for long-term storage at home (stay-in-place) because they are heavy and require long cooking times, making them less practical for taking with you in a bug-out situation.
3. Freeze-Dried and Dehydrated Foods
Freeze-dried foods retain their nutritional value by removing moisture and have an extended shelf life. Main options are freeze-dried meals, freeze-dried fruits and vegetables, dehydrated soups, and powdered eggs and milk.
They are usually much lighter than the original ingredient because the moisture is often the heavy part. That means these foods work well for both stay-in-place plans, where you may have room and cooking options, and bug-out scenarios, since they are lightweight, durable, and only need hot water.
4. Specialty Survival Foods (MREs, Rations, Pemmican)
These foods are made specifically for emergencies. Common options include MREs (Meals Ready to Eat): military rations, self-contained meals. Emergency ration bars (high-calorie, compact), Pemmican (traditional, long-lasting mix of dried meat and fat), Jerky, and cured meats.
Survival food, ready-made meals, and ration bars usually have a shelf life of 5+ years, but stored correctly, some traditional dried foods can last for many decades. These foods are especially ideal when you must bug out—leave your home suddenly and travel on foot—since they are lightweight, tough, and ready to eat without preparation. They are less optimal for long-term, stay-in-place needs because of their higher cost or limited variety, but helpful for emergencies on the move.
Types of Storage and Preservation
How you store your food is just as important as what you choose to store. Heat, moisture, and oxygen can all shorten the shelf life of food.
1. Mylar Bags with Oxygen Absorbers
Mylar bags with oxygen absorbers are a favored method for long-term dry food storage. They prevent oxidation, extending shelf life for many staples. These bags are cost-effective, lightweight, and reliable. Store them in containers that are rodent-resistant, as Mylar itself does not block rodents.
2. Vacuum-Sealed Jars or Bags
Vacuum sealing removes air, compacting food. It’s great for mid-term storage, but bags often lack mechanical strength and are more prone to punctures. Its low cost makes it ideal for storing for 1-5 years, depending on the contents and the environment in which they are stored. Good for dehydrated fruits, nuts, and meats.
3. Canning (Pressure or Water Bath)
Home canning allows you to preserve fresh produce, meats, and soups, and is especially useful for preserving your own excess garden produce or making produce available out of season. There are several types of canning, and the appropriate one needs to be used depending on the produce. Pressure canning is required when acidity is low because higher temperatures are needed to kill bacteria. Higher acidic contents can be canned in a water bath. There is also pickling, where acidic vinegar and salt are used to preserve food for a shorter term, with a change in flavour.
The shelf life depends on how well you kill off the bacteria and seal the containing jars. This can be just a few months to a few years.
4. Freezer Storage
Frozen foods offer variety, convenience, and good nutritional retention, but require electricity. In an emergency, this can be a problem unless you have your own electrical source. Any extended outage may cause food to spoil. While frozen foods are useful for planning your family’s food supply, they should not be your main survival food plan. Frozen food can last from 6 months to 2 years, depending on the type.
Duration of Storage (How Long Should You Prepare For?)
A good emergency food plan should cover different time periods.
1. Short-Term Supply (72 Hours)
At the very least, your emergency food supply should last for three days. This is often the length of time the emergency services need for you to be self-sufficient whilst help is organized. It is possible to fit this into a go-bag as well as keep it in your home at any given time. The latter really should have a lot more.
2. Medium-Term Supply (2 Weeks – 3 Months)
The go-bag is not designed for these durations, but it may still include items that last longer than 72 hours. For example, water filtration and purification could last for many weeks. First-aid items and tools could be useful in the long term. To last in the medium term away from your home, you need to get to a place with supplies, and the bug-out bag is what gets you there. Of course, depending on your situation, you may have storage elsewhere prepared for just that occasion.
3. Long-Term Supply (6 Months – 5+ Years)
A long-term survival food strategy is mainly for people in outlying areas where help may be a long time coming. Areas that are difficult to reach in winter, where normal civil society cannot provide emergency cover, or where civil society has completely broken down. Food stocks will have to be monitored for date and, if required, replaced or revolved over time.
Stay-in-Place vs. Bug-Out: How Survival Food Planning Changes
A key part of prepping is deciding whether to stay or evacuate. Your food plan must address both, but obviously, be very different in makeup.
Stay-in-Place Food Strategy. This gives a lot more options, especially if you have space to store food in a cool, dry, well-organized manner. The types of food will be more varied, as you will probably have access to cooking and more water. There will be larger quantities, and you will have long-term food options.
Bug-Out Food Strategy. This requires you to leave quickly, travel light and fast, and be ready to pick up and go. It requires: lightweight, high-calorie, minimal or no cooking, durable packaging, and compact storage. Best bug-out foods: MREs, ration bars, jerky, nuts and seeds, freeze-dried meals. A bag should have three days’ lightweight, ready-to-eat food.
Final Thoughts
A strong food strategy relies on proper long-term storage, choosing versatile foods, and rotating stock for freshness. By focusing on methods like mylar storage, freeze-drying, canning, and building layered supplies, you protect your household from surprises.
