I’m a poor person, I know a lot about how food lasts beyond expiry dates.

There’s being overly afraid of going past best-by date, and there’s being stupid by eating 2 weeks old leftovers from the fridge.

After 5 days I wouldn’t eat anything opened or already cooked from the fridge that isn’t naturally preserved (like cheese or sour cream). Things go bad in the fridge too.

I’ve not tried 2 weeks old rice, and I don’t want to. You want to keep something edible more than a few days, that’s what the freezer is for.
