How to Tell if a Banana is Bad?

If you have ever bought a ripe banana, you know that it may not taste as good as you expected. If you notice that the peel starts to turn yellow or has brown spots, you should throw it out immediately. It’s also possible to smell the fruit. If the banana smells like rotten eggs, then you should discard it. However, if the banana has an unpleasant smell, it’s probably already past its prime.

The first clue is the color of the banana. If the banana is black, it’s overripe and will not ripen further.
