How do you know olives are still good?

There are a few ways to tell if olives are still good:

* Smell: Olives should have a slightly salty and fruity smell. If they smell off, they are likely spoiled.

* Taste: Olives should taste slightly salty and briny, with a hint of bitterness. If they taste sour or rancid, they are likely spoiled.

* Texture: Olives should be firm and plump. If they are mushy or soft, they are likely spoiled.

* Color: Olives can vary in color from green to black, depending on the type of olive. However, they should be consistent in color throughout. If there are any dark spots or discoloration, the olives are likely spoiled.

If you are unsure whether or not olives are still good, it is best to err on the side of caution and discard them.
