Two things can happen to cooking oil over time. It can become stale, which means that the flavour becomes flat and unappealing, or it can become rancid, which means that it becomes sour. Either way, you don't want to use it. Either way, use your taste buds and ignore expiration dates. Oil stores better in cool places and when it is sealed, and when properly stored can be used long past the expiration date.
Usually until the expiration date.
no, this is long past its expiration date, throw it out and buy new.
As long as the can is not damaged....for as long as you can think. (Unless it has an expiration date on it!)
Who knows? Is there an expiration date? If not, check their website (if they have one.)
Cooking shortening is made to last a long time. It contains preservatives that allow this. Each container of shortening will have an expected life date on it. Look for the expiration date.

The can should have an expiration date on it. That doesn't mean that it is bad once that date has passed, but could be risky.
Well it depends on what kind of food brand is in the box. If it is cereal or cookies after the expiration date they will be stall.
Every package of salami should have an expiration date that you should go by. If there is no expiration date, the salami should last up to week after opened if in a sealed package or container.
The same as cake mix. Approx. 3-5 months.
Maalox is no longer any good after the expiration date. When the expiration date has passed it means that it is no longer as effective as it once was.
The expiration date is there for a reason. If it's a cheesecake which doesn't use preservatives, then the expiration date is probably pretty accurate.
