An unexpected snowstorm, tornado, flood, or power outage can create supply and food security problems. To be prepared for such emergencies, experts recommend having a three-day supply of food and water on hand. The Centers for Disease Control and Prevention (CDC) recommends storing 1 gallon per day for each person and, if possible, recommends creating a two-week supply. Don't forget to store more water if you have pets.
Accumulate enough food to provide at least 2000 calories and 1 gallon of water per day, per person in the event of an emergency or natural disaster. The minimum storage requirement for the 72-hour emergency kit, suggested by the Federal Emergency Management Agency, is 6000 calories and 3 gallons of water per person. If you and your family need to prepare for two weeks or more of food, pay attention to nutritional needs. Plan food supplies so that everyone can eat at least one well-balanced meal every day.
The shopping list mainly includes non-perishable canned foods with some perishable foods that are easy to find and store. When you're determining if a food is good for storage, ask yourself a few simple questions about each food you're considering. If you're interested in storing most of your emergency food such as dry foods such as dried beans, polished white rice, hard and soft grains, read Ready Squirrel's article, “How Much Food to Store Per Person.” According to the Federal Emergency Management Agency, store a minimum of two weeks of emergency food or 28,000 calories and fourteen gallons of water per person. Another reason you need to have emergency food ready to eat is because it's not always safe to cook after a disaster.
The foods in the table are based on FEMA suggested short-term emergency foods that are ready to eat, non-perishable, that do not require special preparation, water, or refrigeration. Once you've figured out your financial situation and are able to move forward with your emergency food storage plan, consider purchasing based on the three different levels of potential emergency scenarios. The charts below illustrate the amount of food that must be stored for a one-day emergency food supply for one to four people. While there are many items in your home that you rely on every day, emergency kits should contain the essentials essential for each person in your family to survive, such as fresh water, food, and medical supplies (including prescription drugs) for three days or two weeks.
That said, I would only recommend keeping canned food past the expiration date if you are currently in an emergency situation where you can't make it to the store. Your 72-hour emergency supply goal should be to store high-calorie foods that sustain you in the short term. Hopefully, you already know that you need emergency food storage to be prepared for disasters such as hurricanes, earthquakes, EMP, or even personal disasters such as losing a job. In the US, store enough survival foods to provide 1600 to 2400 calories per day for adult women, 2000 to 3000 calories per day for adult men, and 1000 to 2000 calories per day for children.
