White Spots On Cantaloupe: What It Means And What Should Be Done About It

White Spots on Cantaloupe

Despite being unsightly in appearance, spots that appear on produce aren’t always a bad thing. Sometimes, the fruit is simply bruised or has developed a few patches but is perfectly safe to eat.

Other times, patches that appear on fruit, and specifically white patches on cantaloupe, can mean that the fruit is growing mold and probably shouldn’t be eaten.

If you notice white spots on the exterior of your cantaloupe, give the cantaloupe a good squeeze. A good cantaloupe may give slightly, but generally, your cantaloupe shouldn’t give too much.

If you notice that your cantaloupe is soft when squeezed, is mushy, or has an otherwise unsightly appearance along with the white patches, you are better off not purchasing, or eating, this particular melon.

White Spots on Cantaloupe Flesh

Does your cantaloupe have white spots on its flesh? If so, you may wish to avoid eating it.

White spots on the flesh of cantaloupe could mean a variety of things, but if you aren’t sure, don’t take the risk.

Although eating mold does not always hurt you, the truth is that some mold types can. If you choose to eat a melon that is showing signs of rotting you run the risk of developing foodborne illness as many instances of food poisoning are caused by fresh produce.

Having said this, it is important to understand that not all white spots on the flesh of cantaloupe mean mold. Sometimes fruits develop spots on their flesh for completely benign reasons. If you do notice white spots on the flesh of the fruit, it may be best to check for other signs of spoilage as well.

Signs of spoilage include:

  • Bruised Skin or Flesh
  • Wrinkling Skin
  • Mushy Flesh
  • Discolored Flesh
  • Insects
  • Mold Growth

Causes of White Spots

White spots can happen for a few different reasons. Some are no big deal, while others might be a sign of something more serious.

Fungal Infections

Fungi love warm, damp places, which makes cantaloupe fields and storage areas a perfect spot for them to grow. Common fungal diseases that affect cantaloupes include powdery mildew and downy mildew, which can show up as white, powdery spots on the fruit’s surface.

As a shopper, you can lower the risk of fungal problems by keeping your cantaloupe in a cool, dry place and eating it before it goes bad.


This happens when the fruit sits in strong, direct sunlight for too long, making the skin change color and develop white or pale patches. Sunscald is more likely to happen to cantaloupes that don’t have enough shade from their own leaves or other plants nearby.

While sunscald itself won’t hurt you, it can make the fruit more likely to get infections or attract pests.

Pest Damage

Lastly, white spots on cantaloupe flesh could be a sign of pest damage. Bugs like aphids, mites, and whiteflies can nibble on the fruit, leaving behind small bite marks that might look like white or light-colored dots. Sometimes, these pests also leave behind a sticky stuff called honeydew, which can attract other bugs and cause sooty mold to grow, making the cantaloupe’s surface look even worse.

Are the White Spots on Cantaloupe Flesh OK to Eat?

You could take that risk, but be careful.

Eating the flesh of a fruit that looks abnormal could be safe, but you need to be sure that the fruit actually is safe before eating it.

If you are unsure, it is always best to avoid eating the fruit.

If, however, the white spots on the flesh of your cantaloupe don’t appear to be mold and appear to be only in one particular location of the fruit, you may consider cutting the infected part out and eating the rest of your cantaloupe.

Still, if you notice that the majority of the cantaloupe flesh is covered in white spots or that there are other signs of spoilage that indicate your cantaloupe has gone bad, be sure to pitch the melon and avoid eating it. Doing so will help you avoid the risks of getting sick from having consumed a potentially rotten cantaloupe.

Impact on Health

While white spots on your fruit might seem concerning, they don’t always indicate a health risk. However, it’s important to understand when these spots could potentially be harmful.

  • Fungal Infections: One of the most common causes of white spots on cantaloupe is fungal infections like powdery mildew. While consuming cantaloupe with powdery mildew is generally considered safe, it’s best to avoid eating fruit with extensive fungal growth. If the white spots cover a significant portion of the cantaloupe or are accompanied by other signs of spoilage like soft spots or an off-odor, it’s safer to discard the fruit.
  • Pesticide Residue: In some cases, white spots on cantaloupe might be caused by residue from pesticides or other agricultural chemicals. While these substances are regulated and deemed safe in small amounts, it’s always a good idea to thoroughly wash your cantaloupe before cutting and consuming it. This helps remove any potential residue and reduces the risk of ingesting harmful substances.
  • Spoilage and Foodborne Illness: If you’re unsure about the cause of the white spots on your cantaloupe, it’s better to err on the side of caution. Avoid eating cantaloupe that has an unusual odor, feels soft or mushy, or shows signs of mold growth beyond just a few small white spots. These could indicate that the fruit has started to spoil, increasing the risk of foodborne illness.

Mold on Cantaloupe

Remember, consuming some types of mold may not hurt you–but some types certainly will.

With this in mind, it is important to avoid consuming mold on fruits, especially if you have a sensitivity to mold or have other respiratory sensitivities, such as asthma.

Mold on cantaloupe can show up in a variety of hues including white, pink, blue, and black. Thus, it is important to be able to identify these types of mold and avoid eating them when you can.

Black Spots on Cantaloupe

If you notice black spots on cantaloupe, pay very close attention.

Unlike answering simple questions about fruit like, “How to clean grapes?” we can’t give you a step-by-step on how to wash away black spots from cantaloupe. That’s because black spots on cantaloupe could mean that the fruit is rotting or is infected with a disease of sorts. And because some molds are black, it is possible that the mold occurring is a toxic black mold that is known to cause deadly infections.

If you notice black spots on your cantaloupe before purchasing it or after having brought it home, it is best to avoid the fruit rather than try to eat it because of the risks associated with black spots and mold on cantaloupe.

How Can You Tell If a Cantaloupe Has Gone Bad?

If you pick up your cantaloupe and it looks funny, feels light in your hands, sounds hollow, or is soft when squeezed, the melon is likely depleted of water and has gone bad.

Moreover, rotting cantaloupe may have a fruity fermenting smell associated with it going rancid. The cantaloupe’s flesh will likely also be mushy and unappetizing.

What Does a Good Cantaloupe Look Like?

Good cantaloupe will typically be firm to the touch, have a pleasant aroma at the stem core (where it has been cut), and will be void of discolored black, pink, white, or blue patches that could be indicators of mold.

If you smell a melon at its stem core, be sure to note if the smell is displeasing or if there isn’t a smell at all. The former is a sign that the cantaloupe has gone bad while the latter is an indicator that the melon is underripe.
