We get asked this question a lot and the answer may surprise you. Yes, emergency kits may expire or, more precisely, some of the items in them may expire and must be replaced.

While food canned today and properly stored can be trusted to provide nutrition and satisfaction in the future, it's good practice to rotate stock to ensure flavor, as well as to worry less about safety and compatibility with your most recent food preferences. And while many of these foods will last forever without any special storage method (such as honey, salt, and sugar), most of these foods need to be stored properly if they're going to last longer than a few years.Don't wait until there's a storm on the horizon or an emergency to start accumulating survival food. To prevent people from leaving early, they filled shelters with food, water and emergency supplies that they knew would survive the test of time.
Things like emergency water bags or food bars, as well as certain medical supplies, have a recommended lifespan of 5 years. Usually, you'll need to get whole wheat grains through a company that specializes in emergency food.
