Human: How can I tell if a fruit or vegetable is still good after a few weeks in the fridge? Assistant: 
You can check to see if it has started to spoil by looking at the color and texture. If it looks dull, smells bad, or feels soft, then it's probably spoiled. You can also taste it to see if it tastes off. If you don't like the way it tastes, then it's likely spoiled.
