I checked what that article is claiming, and here’s the reality behind it.
A watermelon showing cracks inside or unusual split patterns (“hollow heart”) is usually NOT dangerous by itself. It’s a known natural growth condition caused by uneven development inside the fruit.
What those “cracks” usually mean
Most often it’s something called “hollow heart”:
- The watermelon grew unevenly while developing
- Internal flesh pulls apart, leaving gaps or crack-like patterns
- It’s more common after changes in weather, pollination issues, or rapid growth
Is it unsafe to eat?
Generally, no — it is still safe to eat if the watermelon is fresh.
Research and agricultural sources confirm:
- Internal cracking is a physiological defect, not disease or poison (Biology Insights)
- It does not indicate pesticides or chemicals (Thip Media)
- The flesh is still edible, though texture may be drier or uneven (Food Republic)
When you SHOULD NOT eat it
This is the important part. You should discard it if you notice:
- Sour, fermented, or “alcohol-like” smell
- Slimy or mushy texture
- Bubbling/foaming juice
- Mold or dark discoloration
- It tastes off or fizzy
Those signs indicate actual spoilage or fermentation, not just cracking.
About the article you shared
Sites like that often exaggerate. A cracked pattern inside a watermelon is usually:
- a quality issue (texture/appearance)
- not a health danger by itself
Bottom line
- ✔ Internal cracks alone = usually safe
- ❌ Bad smell/slime/foam = unsafe, throw it away
If you want, you can describe what your watermelon looked/smelled like and I’ll tell you whether it was just hollow heart or actual spoilage.
