What a short duration is, and how it exactly impacts MRE shelf life, is anyoneâs guess. Chilling MREs in the fridge undoubtedly extends the shelf life of MREs, however it is not specified by how much. Some sites selling MREs claim they last as long as 130 months (almost 11 years) at 60 F (15 C) .
For example, storage at 100Â° for 11 months then moved to storage at 70Â° would lose one-half of the 70Â° storage life. Also avoid fluctuating temperatures, in and out of freezing levels. Due to the cumulative effect of time and temperature, a regular rotation of MRE's within 5 to 7 years is recommended.
