MRE or “Meal Ready to Eat” constitutes food supply rations that have comprehensive food supplies within the package that one can consume during emergencies. In the event that disaster or uncertainties strike, an MRE becomes handy and it can be your savior when you cannot access regular supplies of food.
A single MRE is said to represent one meal so three MREs per day can satisfy your daily meals especially if you are in the army. However, the pertinent question that you may need to ask is: “How long does MRE last?” As such, keep on reading this guide since it gives you insight into factors that can affect the lifespan of an MRE.
Life Span of an MRE
But how long do mres last? The lifespan of an MRE is not fixed since it can be anything between one month and 10 years depending on a number of factors. Essentially, the way an MRE is stored determines its lifespan since it is sensitive to aspects like temperature. The packages are easy to open but once opened, the contents should be consumed forthwith especially if you are in the jungle.
Storage and durability of MRE
The storage temperature of an MRE determines its lifespan and how long do mres last. For instance, the expiration date of an MRE that is stored at room temperature of about 49° C degrees Celcius (or 120° F) can last for about one month only. When you lower the temperature to about 10 degrees Celsius (or 50° F), then the MRE can last up to more than 5 years.
However, you should know that this timeframe your MRE can last depends on constant maintenance of the storage temperature of 75° F during those 5 years that it will last. It follows that higher temperatures reduce the shelf-life of the MRE while lower temperatures can help extend the lifespan of the MRE.
It is also imperative to know that fluctuations in temperature can affect the quality of the MRE. For example, you start off your MRE in a temperature of 90° F then shift it to 75° F, it may not be good for the next 5 years. It is important to maintain the temperature at a constant level.
You can also check the diagrams that can give you insight into the mre shelf life depending on the temperature. It is possible that some MREs can even last up to 10 years if kept in colder conditions. The most important thing that you should be watchful about pertains to maintaining your MRE at a lower but constant temperature to increase the longevity of the shelf life.

Freezing the MRE can significantly help increase its lifespan but this is not the best option to take. The layering of the packaging of the MRE may not be suitable to sustain the frozen condition. In some cases, power outages can lead to temperature loses which results in fluctuations of the desired constant temperature.
As a result, the packaging and mre shelf life can get damaged which results in the MRE losing its preservation.
