How to store cut cucumbers
Cover cut or sliced cucumbers with plastic wrap. The USDA says this keeps fresh and cut produce moist and away from mold spores in the air. FoodKeeper’s cucumber line gives no separate time for cut cucumbers, so check them for mold before you eat them.

How to tell if a cucumber is bad
Throw out a cucumber that has mold or looks rotten, as the USDA and the FDA advise.
Can you cut mold off a cucumber?
No. The USDA’s guidance on molds in food says soft fruits and vegetables with high moisture content, including cucumbers, should be thrown out when moldy. They can be contaminated below the surface, so cutting off the visible mold isn’t enough.
What if a cucumber is bruised or damaged?
Cut away the damaged or bruised areas before you prepare or eat the cucumber. The FDA gives that advice for all produce, and says to throw away any produce that looks rotten.
How to wash cucumbers
Rinse cucumbers under plain running water and scrub them with a clean produce brush. The FDA names cucumbers, along with melons, as firm produce to scrub this way.
Wash them before you prepare or eat them, even if you plan to peel them, so dirt and bacteria aren’t carried from the surface when you peel or cut.
Then dry the cucumber with a clean cloth or paper towel to further reduce bacteria, as the FDA’s tips for cleaning fruits and vegetables advise.
What to look for when buying cucumbers
Look for cucumbers that aren’t bruised or damaged. For pre-cut, bagged, or packaged cucumbers, the FDA gives two more rules.
- Buy them only if they are refrigerated or surrounded by ice.
- Refrigerate them at home.
Frequently asked questions
Where do these storage times come from?
The storage times come from USDA FoodKeeper, a food storage guide from the USDA Food Safety and Inspection Service. The advice on mold, washing, and buying comes from the USDA and the FDA.
When do the 4 to 6 days start counting?
They start on the day you bought the cucumbers. USDA FoodKeeper gives the time from the date of purchase.
Can you use soap or produce wash on cucumbers?
No. The FDA doesn't recommend soap, detergent, or commercial produce wash, because produce is porous and can absorb them. Plain running water is all you need.
Does washing remove all bacteria from a cucumber?
No. Washing reduces bacteria but doesn't eliminate them, and drying the cucumber with a clean cloth or paper towel reduces them further.
Should pre-cut or packaged cucumbers go in the fridge?
Yes. The FDA says to refrigerate all produce that is bought pre-cut or packaged.
