What is an MRE?
MRE stands for meals ready to eat. The main entrees are sealed in a triple layer pouch and then cooked inside so the food is never exposed to the air until it's ready to be eaten. They can be eaten at room temperature or heated with the enclosed heaters. They can be stored for 5-10 years depending on temperature. The shelf life time was established purely for taste. The acceptable nutritional value and product safety will last far beyond the point of taste degradation.
These are great for camping or emergencies. Having these on hand will give you the peace of mind knowing you have nourishment for you and your family in case of a hurricane, flood, earthquake, blizzard, bird flu pandemic or act of terror.
