I’m done testing the expiration limits. I ate a can of soup that was maybe 4 months past its due date. Opened it first. Smelled fine. But something about the consistency seemed slightly different. But no big deal, I thought. I was sick from both ends for the next 3 days. I’m done with that. Don’t even think about it.
I grew up eating home canned food.
Most things you just removed the mold on top and ate it. My mother lived to just short of 98 and my father 90 yrs old eating the same.
Texture, Taste and Smell tests were important. If the dog turned his nose stay away as he ate dead groundhogs.
The same was true of fish and wild game even when fresh. You watched for worms and diseases in the animal prior to cooking it. (I always disliked biting into the lead shot though)
“I was sick from both ends for the next 3 days.”
The key is to whistle. If it comes over submissively, go ahead and eat. If it snarls in defiance...shoot, shovel and shut up.
You likely did not heat it high and long enough, as that would kill bacteria, although toxins it produced would remain. Beware of tomato products, for due to the PH bacteria tends to grow (and of course, throw out any puffed can), while non-fat (fat grows rancid) high sugar products can last quite long.
