Question: The mainstay i got has not expiration date.  It is blank where it says "Exp date:"Is there another way to find out?
Document: I got a pack of these because I was close to free shipping on some other items. I figured I'd try it out and see how it went, but the expiration dates have been removed from the food so theres no real way to be able to tell if its safe for human consumption. I kept the one I bought though, figured if I was half dead I could take a chance on some expired food rations. Just be aware, dont buy this as your main survival food.
just sitting there) and 3 days @ 3 bars/day on land. The calorie count would be 800 and 1,200 per day, respectfully.Forth: Contains Partially Hydrogenated Oil, i.e. trans fat, but hey, I think shelf life in this case outweighs the bad. Besides its not meant to be eaten often, hopefully you only eat it because you got curious.Fifth: The Mfg Date, Lot #, and Exp Date, has appeared to rubbed off.
I ate one of these rations the moment i got them and it was actually pretty good. Did need a little water afterwards, but could manage without if needed. The expiration date is in 2017 which is what I would expect from a "5 year shelf life" statement. Will be buying many more over the coming days
Great for emergency rations that don't take up a lot of space or weigh a lot. The date they are produced is stamped on the package as well as the expiration date (which is 5 years after production date).I don't plan on munching on them for snack food around the campfire, but if I got stranded, stuck, or otherwise ran out of other food, it's nice knowing I have several days of food in one fairly compact package.
While this is not gourmet eating, it is food. Purchased 8/2012 with an expiration date of 7/2017, so it's prettty "fresh". I tried a package on a recent backpacking trip to test bugout equipment and It got old really, really fast (the taste that is). However when faced with a survival situation I am sure eating one of these will not be an issue. My package came sealed neatly and when opened the 9 bars within broke apart easily into the proper portion size.
I had ordered this product a year ago and had put it away as soon as it received, upon cleaning my pantry i noticed it and immediately looked at it to see what the expiration date was, amazingly there is no date printed for expiration or mfg date or lot #. goes into the bin immediately. in the future i will definitely ask the seller for mfg/exp date info prior to purchase and validate upon receipt of item, what a waste. hope this doesnt happen to others looking to purchase this item
I have read great reviews about this ration and am give it 4 stars only because I have not tasted it myself even though people say they like it. I am sure it will suffice in an emergency situation. One of the mainstay packs lost the seal and will be returned. Make sure to check for that and the expiration date.
The second was almost as good as the first. The third, I noticed an odd, not unpleasant, but hard to define after taste. The fourth the after taste got stronger. And halfway through the fifth, it suddenly turned into the most revolting thing I had ever had in my mouth, and it was all I could do not to spit it out on the floor.The exact point varies from one individual to another.
I opened one just to try it as I ordered 5 total, the taste is not bad for the purpose they serve... survival,  but I need to know I can store these for as long as possible and sending me ones that are already 1/2 way through the shelf life is not OK in my book, so I am sending the other 4 back and hopefully will find a supplier that will send &#34;fresh&#34; product.
I got these as part of a last ditch disaster kit along with the Datrex water and some other items with the sole intent to have these for a medium-term storage. The idea is to have some of these in a car/truck BOB and the package does take up more space than I prefer, and there's no way to break it down into smaller portions without opening the whole thing.
Answer: yes
