Also know, do emergency rations expire?
Emergency Food and Water has expiration dates. Most food bar rations come with a 5 year shelf life and so do most drinking water rations in foil packages (pouches) and cardboard containers.
Keeping this in consideration, how long do food rations last?
The average MRE shelf life lasts five years in 75 degrees F. If kept in cooler conditions, they can last well over 10 years and still be safe to eat. However, you should note that an MRE will only last about a month if stored in 120 degrees F.
Overall: Although it looks and smells very similar to many of the other ration bars, the SOS bars are a bit more cookie-like. The texture is not as hard or dry as the others in this taste test, and the flavor is a bit sugar cookie-like.
