The best quality beef in the world would “no longer be food” after 30 years! Not even freeze dried meat would be recommended for human consumption by then.
The Pigs would turn up their noses and walk away insulted, if offered this as feed.
“Not even freeze dried meat would be recommended for human consumption by then.”
Freeze dried food , and frozen food is edible indefinitely. Case in point scientists ate 50,000 year old bison that was frozen and desiccated in permafrost. They made a stew of it and were fine. There can be no bacterial life in subzero frozen or less than 5% moisture by mass that’s just biological fact.
Hermetically sealed canned food has been eaten 100 years after it was canned some from the seafloor where it say gor the duration. Again sterilized hermetically sealed containers do not allow bacterial life either. Only rarely anoxic bacteria get past the sterilization process and then you have contaminated canned food which would be obvious from the gasses they produce inside the can it a rare and a flaw in the process not that bacteria can just spontaneously appear inside a sealed sterilized container.
I personally have eaten MCI aka C-rats from the Vietnam war era in the 1990s well over 20 years old stored in the Texas heat in quonset huts on a base since well Vietnam.We were fine it was a right of passage on your first FTX with the unit. I also have eaten frozen venison that was at least ten years old vacuum sealed found after my grandfather passed in the garage freezers I remember shooting and packing that meat as a kid at least a decade before. Again meh not a big deal frozen food is good indefinitely the FDA also agrees it’s in their guidelines if one take the time to look. Freeze dried food is good for decades you can buy 25 year freeze dried prepper food stocks it’s Gucci expensive. Or you can get a vacuum pump and make a unit yourself as a prepper I did it takes two weeks to completely dry soups or chillis, solid meats also take at least two weeks it’s then self stable as long as it’s sealed and dry for all eternity organisms simply cannot grow in a bone dry environment. I pack that homemade food all over the wilderness for weeks at a time while hunting it doing geology work never seen refrigeration since it came out of the vacuum unit.
