You Cut Open a Watermelon and Found Cracks? Stop Eating It Until You Know What They Mean

Some online posts claim that cracked watermelons are always caused by excessive use of plant growth regulators.

Experts say the situation is more complicated.

Certain growth regulators have been used in agriculture to improve crop production in some regions. When used according to regulations, they are intended to help crops grow properly. However, improper use or misuse has raised concerns in some cases.

Because consumers cannot determine the cause simply by looking at the fruit, experts recommend paying attention to the watermelon’s overall freshness rather than assuming cracks alone indicate chemical use.

Signs You Should Not Eat a Watermelon

Experts recommend avoiding watermelon if you notice:

  • A sour or fermented smell
  • Mold on the rind or flesh
  • Slimy texture
  • Dark or discolored flesh
  • Large soft or rotten areas
  • Leaking liquid

These signs suggest spoilage rather than a simple internal crack.
