You are supposed to wash watermelon before you cut into it.
Even though you don’t eat the rind, washing watermelon is important because bacteria on the outside can transfer to the flesh when your knife slices through.
The FDA actually recommends washing all produce, including watermelon, before preparing or eating it.
So if you’ve been wondering whether you should wash watermelon, the answer is a friendly yes.
In this post, we’ll look at why you should wash watermelon, how to wash watermelon properly, and what happens if you skip this simple step.
Let’s dive in.
Why You Should Wash Watermelon
You should wash watermelon because the outside of the melon can carry dirt, pesticides, and harmful bacteria like Salmonella.
Here’s why washing watermelon matters more than you might think.
1. Bacteria Transfer During Cutting
When you slice through an unwashed watermelon, your knife drags whatever is on the rind right into the flesh you’re about to eat.
This is the main reason you should wash watermelon before cutting it.
Even if the inside looks perfectly clean, the contamination happens in that single slice.
2. Watermelons Grow on the Ground
Watermelons grow in soil, which means they can pick up dirt and bacteria from the ground.
They also get handled by multiple people between the farm and your kitchen.
That journey is another reason washing watermelon is a smart habit.
3. Pesticide Residue Can Linger
Conventional watermelons may have pesticide residue on the rind.
While you don’t eat the rind, that residue can still transfer to the flesh when you cut it.
Washing watermelon helps reduce this risk and keeps your fruit safer to enjoy.
4. It’s a Quick and Easy Step
Washing watermelon takes less than a minute.
For such a small effort, it’s worth it for the peace of mind alone.
So yes, you should wash watermelon every single time.
How to Wash Watermelon the Right Way
Washing watermelon properly is simple, but there’s a right and wrong way to do it.
Here’s how to wash watermelon so it’s actually clean and safe.
1. Rinse Under Running Water
Start by holding your watermelon under cool running water.
Use your hands or a clean produce brush to rub the entire surface.
Running water is better than soaking because it helps rinse away bacteria instead of letting it sit.
2. Skip the Soap and Bleach
Never use soap, detergent, or bleach when washing watermelon.
Produce is porous, and these chemicals can soak into the rind and end up in the flesh.
Plain water is all you need for washing watermelon safely.
3. Dry It With a Clean Towel
After washing watermelon, pat it dry with a clean paper towel or cloth.
Drying helps remove any remaining bacteria and keeps the surface from getting slippery while you cut.
4. Wash Before You Cut, Not Before You Store
Only wash watermelon right before you plan to cut it.
Washing watermelon and then storing it wet can encourage mold growth.
Keeping it unwashed until slicing time is the safer approach.
What Happens If You Don’t Wash Watermelon?
If you don’t wash watermelon, you’re not automatically going to get sick, but you’re definitely increasing your risk.
The CDC has linked outbreaks of foodborne illness to contaminated melons, including watermelon.
When you skip washing watermelon, you’re basically gambling with bacteria you can’t see.
1. Higher Risk of Food Poisoning
Bacteria like Salmonella and Listeria can live on the rind of a watermelon.
Once you cut through it, those bacteria get a free ride into the fruit.
That’s why you should wash watermelon, especially if you’re serving it to kids or anyone with a weaker immune system.
2. Shorter Shelf Life
Cut watermelon that was washed properly tends to last a bit longer in the fridge.
When you don’t wash watermelon before cutting, you’re introducing bacteria that speed up spoilage.
So washing watermelon isn’t just about safety, it’s also about getting more mileage out of your fruit.
3. You Might Not Even Notice
The tricky part is that contaminated watermelon often looks and tastes completely normal.
You won’t see the bacteria, and you won’t taste them either.
That’s exactly why washing watermelon should just become part of your routine.
So, Are You Supposed to Wash Watermelon?
You are supposed to wash watermelon before cutting it, and now you know why.
The rind can carry dirt, pesticides, and bacteria that transfer to the flesh when you slice.
Washing watermelon under running water with a bit of scrubbing takes less than a minute.
So the next time you bring home a melon, don’t skip this step.
Washing watermelon is one of those tiny habits that keeps your summer fruit safe, fresh, and ready to enjoy.
