Use by dates were invented by places like farms and stuff because the cans were lasting too long. Also, a sell by date is not a use by date, a sell by date means you probably have about 10 more dates.
This is why I will not allow the husband to shop at Costco anymore and like all that. He'd buy huge containers of tinned tomatoes and then dump half of them later and I'd be screaming, "Is it dented, is it bulging IF NOT PUT IT BACK." We actually had arguments where I would open up a tin and spoon it into my mouth going "It's delicious, it's FINE."
You can carry this too far: take care of your eggs. I once pulled an egg out of my mom's "gourmet egg holder" and split it into a jar, and it was GREEN the yolk. I said cautiously to my mom, "Do you know when you last bought eggs and she waved her hands and went, "Oh you know...." I was like, "I do NOT know that is my point and I want to know its age, and also tell you to keep them in the cheap paper cartons and ONLY keep them a month after their due date.
I mean I am fairly certain I coulda ATE it I had a cast iron stomach and still do. But somehow green is not a good look for an uncooked egg.
LOL, I am going to make it pretty far in the zombie apocalypse. I have old meds I really wouldn't CARE to use unless I HAD to but most meds are fine years after the sell by date just less potent, I guess.
Some like Wellbutrin you really gotta watch the sell by date, but you open it up... it just smells off, a bit like rotten eggs, oddly. I think that bottle was out of date by like 5 years though.
