It is more likely to go "good" (turn to alcohol) than to go bad. It can crystallize though.

Fresh magic mushrooms will go bad quickly. Dried magic mushrooms last much longer but may lose their potency over time, especially if exposed to air and/or stored in hot conditions.
Unopened it will last on the self for a year or more. But once it is opened, it will last a couple of months in the fridge. If you've opened the container or used mayo on a sandwich or in a salad, it shouldn't be left unrefrigerated for more than a couple of hours.
look at the expiration date, if its in the jar in the fridge it should last about 2-3 months. if its on a sandwich it should last a few hours, depending on how cool it is. In my opinion mayo can not go bad in 3 to 4 months because of the vinegar that preserves it
No i don't thing so
Oh yes, after about 3 years.
After a while, white wine can deteriorate in quality.
Onion is what goes bad in the potatoe salad because it attracks bacteria. If you use mayo that is home made then that can go bad but the commercial mayo has preservatives in it. If you put an onion out on the counter when someone is sick and let it there over night you will see how it attracks the bacteria.
definitely! If past the expiration date dispose of it.
Coffee-Mate liquid will usually last 2-3 weeks after opening. If left unopened, it can be stored for several months in the fridge. You will know when the coffee mate has gone bad, because it will curdle, change color, or smell badly. You can usually tell when it is starting to go bad, well before this point because the creamer will not integrate with the coffee immediately, and will leave "rings" on top of the coffee until it is stirred in. However, it is still safe to consume at the "ring" stage. It can be stored even longer in the freezer, but this is not recommended as some separation of the product may occur after thawing.
