Those internal cracks could be the result of a growth-enhancing chemical known as forchlorfenuron. This chemical is sometimes used to accelerate the size and growth of fruits, including watermelon.
While forchlorfenuron is allowed in some countries under strict regulations, concerns have been raised about its potential long-term effects on human health. Some studies have linked excessive exposure to this chemical with possible neurological damage and even cancer risks, although conclusive evidence is still debated among experts.
As a precaution, it’s best to avoid consuming watermelon that displays unnatural internal cracking, especially if it’s accompanied by an odd smell, overly mushy texture, or chemical taste.
✅ How to Choose a Safe, Fresh Watermelon
When shopping for watermelon, keep these tips in mind to choose the best one:
Look for a creamy yellow ground spot — this indicates ripeness.
Pick a heavy one — a juicy watermelon will feel heavier than it looks.
Check the rind — it should be firm, smooth, and free of dents or bruises.
Listen for a hollow sound when tapped — that “thump” means it’s ripe.
Check the stripes — two-finger-width alternating light and dark stripes are a good sign.
