Watermelon is the quintessential summer treat-juicy, sweet, and refreshing. But nothing ruins a sunny day faster than biting into a watermelon only to discover it’s gone bad. Knowing how to tell if watermelon has gone bad can save you from a disappointing snack and potential stomach upset. Here’s a friendly, easy-to-follow guide to help you spot the signs of a spoiled watermelon before you take that first delicious bite.
Visual Signs: What to Look for on the Outside and Inside
1. Check the Rind and Skin
A fresh watermelon has a firm, smooth rind with a consistent deep green color and a creamy yellow “field spot” where it rested on the ground. If you notice:
– Soft or mushy spots on the rind
– Large dents or cracks
– Dark patches or moldy areas
– A dull or faded color instead of vibrant green
These are all red flags that the watermelon may be spoiled or overripe.
2. Look Inside the Flesh
When you cut into the watermelon, the flesh should be bright red or deep pink and juicy. Signs of spoilage include:
– Brown or dark spots in the flesh
– A dull or faded color
– Slimy or mushy texture
– Mold inside the fruit
If you see any of these, it’s best to discard the watermelon.
Texture and Feel: What Your Hands Can Tell You
3. Firmness Test
A fresh watermelon feels firm and dense when you press gently on the rind. If it feels soft, mushy, or spongy, this usually indicates internal rot or overripeness.
4. Weight Check
A ripe watermelon should feel heavy for its size, indicating it’s full of water and juicy. If it feels unusually light, it might be drying out inside or spoiled.
Sound Test: The Hollow Knock Trick
Tap the watermelon with your knuckles. A fresh watermelon typically produces a deep, hollow sound. If the sound is dull or flat, it might be a sign that the watermelon is overripe or spoiled inside.
Smell and Taste: Trust Your Senses
5. Sniff the Watermelon
Fresh watermelon has a sweet, mild aroma. If you detect a sour, fermented, or unpleasant smell-similar to vinegar or alcohol-the watermelon has likely gone bad and should be thrown away.
6. Taste Test (If You’re Unsure)
If the watermelon looks and smells okay but tastes sour, bitter, or fizzy on your tongue, it’s a clear sign it’s spoiled and unsafe to eat.
Other Important Tips
7. Shelf Life and Storage
Watermelon is best eaten within a week of purchase if stored in the refrigerator. Whole watermelons can last about 1-2 weeks at room temperature, but once cut, they should be refrigerated and consumed within 3-5 days to avoid spoilage.
8. Avoid Watermelons Left in Heat
If a watermelon has been left out in hot weather for too long, it can spoil quickly. Signs include a strong bad smell, mushy texture, and visible holes or black spots on the rind.
