If the meals are stored at a temperature of 80 degrees F/26.7 degrees C the current shelf life chart shows they will last a minimum of 36 months.The lower the storage temperature, the longer the shelf life.Due to the cumulative effect of time and temperature, a regular rotation of MRE’s within 5 to 7 years is recommended.The shelf life of the MRE primarily depends upon the temperature at which they are stored.MREs replaced the canned MCI, or Meal, Combat, Individual rations, in 1981, and is the intended successor to the lighter LRP ration developed by the United States Army for Special Forces and Ranger patrol units in Vietnam. During the First World War, canned meats were replaced with lightweight preserved meats (salted or dried) to save weight and allow more rations to be carried by soldiers carrying their supplies on foot.MREs have also been distributed to civilians during natural disasters. At the beginning of World War II, a number of new field rations were introduced, including the Mountain ration and the Jungle ration. Space Program, Military, Forest Service, and FEMA have used MREs since the 1970s.Some of the best information available on MRE shelf life is the storage life chart (see below) compiled by the U. Their opinions were combined to determine when the MRE ration was no longer acceptable.
The additional components within the complete meal are also normally produced within 30 days or less of their packaging date.
Your MRE cases will have a label with the manufacturing date on it.
