1. Visible Mold or Fuzzy Spots
What It Looks Like : White, green, or black fuzzy patches on the rind or exposed flesh.
Why It’s Dangerous : Mold indicates that harmful bacteria or fungi have taken hold, which can spread toxins throughout the fruit—even in areas that look fine.
What to Do : Discard the entire watermelon immediately. Do not attempt to cut off the moldy part, as spores may have penetrated deeper into the fruit.
2. Soft or Squishy Spots
What It Looks Like : Areas of the rind or flesh that feel overly soft, mushy, or sunken.
Why It’s Dangerous : Soft spots are often a sign of rot or bacterial growth, which can compromise the safety and flavor of the watermelon.
What to Do : If the soft spots are minor and only on the exterior, you might be able to salvage the interior by cutting away the affected areas. However, if the flesh inside is also soft or discolored, throw it out.
3. Unpleasant or Sour Smell
What It Smells Like : A sour, fermented, or off-putting odor when you cut into the watermelon.
Why It’s Dangerous : A foul smell indicates fermentation or spoilage caused by bacteria breaking down the sugars in the fruit.
What to Do : If the watermelon smells bad, don’t taste it—discard it immediately. Spoiled fruit can cause food poisoning.
