I had some old civilian MRE's from Sopakco and decided to eat them and get some newer one's. The date code was 9208, which (I thought) was 2009, 208th day, or July 27, 2009. After enjoying my meal of Beef Ranchero with beans, Apple sauce, Crackers and grape Jelly, and pound cake (I am full), I started to think more upon the pack date above. I may have made a mistake. I realize now that these MRE's were given to me shortly after Hurricane Hugo, in 1989, not 2009. This means I just ate a 23 YEAR OLD MRE!!! and it tasted fine and I am not sick after 4 hours. The only thing I did not eat was the grape jelly, as the pack was leaking from being crushed under other supplies. Does anyone know how long these things actually last as the date is the packing date, not the expiration date. When stored at 70 degrees, a military MRE says it should last for 66 months, but is that a BEST IF USED BY date, or an actual expiration?
