One of the foundations of a comprehensive emergency preparedness plan is a food storage supply. Ideally you would have enough food storage for you and your family to shelter in place for at least several months. If you have to leave home you'll want to have at least a 72 hour survival kit. Freeze dried foods and mixes provide the longest shelf life while preserving the taste and nutrition of your food storage. A critical part of your food storage plan is water storage and filters.
