Watermelon is the ultimate summer treat—juicy, sweet, and refreshing. But nothing ruins a sunny day faster than biting into a watermelon slice only to discover it’s gone bad. So, how do you know if a watermelon has gone bad before it’s too late? Let’s dive into the simple signs you can look for to make sure every bite is delicious and safe.
Visual Clues: What to Look for on the Outside and Inside
1. Check the Color of the Rind and Flesh
A fresh watermelon usually has a vibrant, deep green rind with a creamy yellow spot where it rested on the ground. If the rind looks dull, has yellow or brown patches, or shows signs of mold (white, black, or greenish-blue fuzzy spots), it’s a red flag that the watermelon is past its prime.
When you cut into the watermelon, the flesh should be a clear, bright pink or red. If the color looks faded, dull, or has dark spots, it might be overripe or spoiled.
2. Look for Soft or Mushy Spots
A firm watermelon rind is a sign of freshness. If you notice any soft, mushy, or sunken spots on the outside, it means the fruit is starting to rot inside. When you press the flesh, it should feel crisp and juicy, not slimy or mushy.
3. Mold Is a No-Go
Mold on watermelon is a clear sign to toss it out. Mold can appear as fuzzy patches or discoloration on the rind or flesh. Eating moldy watermelon can lead to food poisoning, so it’s best to avoid any melon with visible mold.
Smell Test: Trust Your Nose
Fresh watermelon has a sweet, slightly floral aroma. If you detect a sour, fermented, or tangy smell—think vinegar or alcohol—that’s a strong indicator the watermelon has gone bad. This unpleasant odor is caused by bacteria and yeast breaking down the sugars in the fruit.
If the watermelon smells off, don’t taste it; just throw it away to avoid any risk of illness.
Texture and Taste: What Should You Feel and Taste?
Texture
Good watermelon flesh is firm and crisp. If it feels slimy, slippery, or overly soft, it’s a sign the fruit is spoiled. Don’t try to rinse off sliminess—discard it immediately.
Taste
If you bite into a watermelon that tastes sour, fizzy, or just “off,” spit it out and don’t eat any more. Even if the melon looks okay, an unusual taste means it’s no longer safe.
Weight and Sound: Additional Freshness Checks
Weight
A ripe watermelon should feel heavy for its size because it’s full of water. If it feels unusually light, it might be dried out or overripe.
Sound
Tap the watermelon gently. A fresh, ripe watermelon produces a deep, hollow sound. If the sound is dull or flat, the melon may be spoiled inside.
How Long Does Watermelon Last?
Whole watermelons can last up to two weeks at room temperature if kept in a cool, dry place. Once cut, watermelon should be refrigerated and eaten within 3 to 5 days for best quality. Pre-cut watermelon often has a best-before date—use that as a guide but always check for spoilage signs.
Tips to Keep Your Watermelon Fresh Longer
– Store whole watermelons in a cool, dry place away from direct sunlight.
– Refrigerate cut watermelon in an airtight container.
– Avoid leaving cut watermelon out at room temperature for long periods.
– Use your senses regularly to check for any signs of spoilage.
