Tomatoes are so versatile, they’re practically a staple in every kitchen. But unfortunately, when they go bad, you’ve gotta toss them—and that’s just sad. A word of advice: when you’ve got fresh tomatoes, prioritize them in your ingredient rotation so they never go to waste. They’re so nutritious they deserve a special place in your weekly meals. If they do go bad, there are a few signs to look out for.

Look for cracks, mold spots, sunken areas, or other damage on the outside surface of the tomato. If you see these, they’re done.

Grip, don’t squeeze, the tomato. A good one should be firm enough that it doesn’t sink in as you hold it. Throw it away if it seems soft.

Smell the outside of the tomato. A bad tomato smells pretty rancid—you’ll know.

Slice the tomato in half. Feel the inside; if it feels slimy, trash it.

Inspect the inside of the tomato for mold spots, discolored areas, or foul smells—all signs that it’s time to let it go.
