What’s the shelf life on that canned butter? Thanks in advance.
It may be TEOTWAWKI, but I ain’t gonna go without butter. No way, no how.
There was no drop dead date on it. I would assume, as I assume with all canned foods that it's about 25 years. I don't make that assumption lightly. I've taught food safety classes to young airmen, for both federal and State certifications.
Dented cans are bad. Swelled cans are bad. Throw them away. Don't open them and contaminate the kitchen.
Open undented and unswelled cans and look at and smell of the contents. If it looks ok, and smells ok, it generally is ok.
This is just for commercial canned products, and not home canned. And it is not official advice, it's just what I do in my real world.
