If You Open a Watermelon and See This …Throw It Out
Cutting into a watermelon is usually a refreshing moment — bright red flesh, sweet aroma, and plenty of juice. But if you slice one open and notice foam bubbling or oozing from the inside, stop immediately and throw it away. This isn’t a harmless oddity. It’s a clear warning sign that the watermelon has begun to ferment and spoil, and eating it could be dangerous.
