I have always wondered about food storage manufacturers’ claims about the shelf life of their products. Many claim 30 years shelf life for what they sell. Of course, the question is how can the consumer ever know that this is true?
Many purchasers are dead and buried by the time 30 years pass. Who could ever go back and demand that their money be returned if it did turnout that the product had gone bad?
I know one fellow who obtained No. 10 cans of wheat from a small survival food manufacturer. When he opened a can several years later, to his horror, he found the contents to be moldy. He began opening other cans and found that all of the others were similar. That would obviously be a very bad thing, even something fatal to discover during a long-term emergency.
I believe that many survivalist/preppers, like me, are reluctant to open relatively expensive cans of stored products to test them. Having paid the money for the product, they are reluctant to “waste” it by using it during normal times.
