I've got those small canned hams and lots of spam.....how long do they last....
There’s a new show on one of the foodie networks called eating history. It’s exactly what it sounds like people eating food hundreds or more years old. There is cases where tinned food yes actual tinned cans from over a hundred years ago was found and then taken to a food lab where they tested it for contamination, nutrients and metal.contamination. turns out if properly canned and sealed the food was still biologically sterile and safe to eat, having lost less than half it’s nutrient content. Taste well that’s subjective....
Here’s a surprisingly good article on that from WebMD.
