Cucumbers can carry Salmonella, a bacteria that causes fever, diarrhea, and stomach cramps. To reduce your risk of Salmonella from cucumbers:

Wash thoroughly under cool running water, scrubbing the skin with a clean produce brush—even if you plan to peel them.
Store properly in the refrigerator at 40°F or below, and keep them away from raw meats.
Cut just before eating to limit bacterial growth on exposed flesh.
Discard cucumbers that are part of an active recall or show signs of spoilage.

If you've eaten cucumbers and are experiencing symptoms like nausea, diarrhea, fever, or abdominal pain, don't guess what's wrong.

Explanation

To ensure cucumbers are safe from Salmonella contamination, it is important to handle and prepare them properly. Washing cucumbers under running water can help remove bacteria from the surface. Avoid using soap or detergents as they can leave residues. Storage is also key; keep cucumbers in the refrigerator to slow down bacterial growth. Additionally, cutting cucumbers should be done right before consumption to minimize the time bacteria have to grow on the cut surfaces.

According to research, Salmonella can survive on both whole and cut cucumbers. Therefore, keeping cucumbers whole until you are ready to eat them reduces the risk of contamination. When cutting cucumbers, use a clean cutting board and knife to prevent cross-contamination from other foods. If you experience any unusual symptoms after consuming cucumbers, such as nausea, diarrhea, or abdominal pain, you can check your symptoms with a free AI-powered assessment to help determine if medical attention is needed. By following these steps, you can enjoy cucumbers safely.
