The Right Way to Wash Produce Before Storing or Freezing

Storing fresh produce safely requires careful handling before it goes into the fridge, pantry or freezer. Washing fruits and vegetables at the wrong time can speed up spoilage or fail to remove harmful bacteria. Experts now recommend specific steps to keep food fresh while reducing health risks.

For most produce, washing just before eating or cooking remains the best practice. This prevents excess moisture from encouraging mould or bacterial growth during storage. However, freezing changes the rules—washing must happen beforehand, as freezing does not kill all bacteria.

Bacteria like *Listeria monocytogenes*, *Salmonella* and *E. coli* thrive in damp conditions, especially in fridge vegetable drawers or pantry storage. A simple cold water rinse removes dirt and some germs, while a brush works well for firmer items like melons or potatoes. Leafy greens need extra care: swishing them in cold water, then drying thoroughly with paper towels reduces contamination risks. Before freezing, produce should be washed and dried completely. Spreading it in a single layer on a baking sheet first prevents clumping. Once frozen solid, it can be transferred to bags or containers for long-term storage. Clean hands are also essential—washing them before handling produce stops germs from spreading.

The right washing method depends on how and when the produce will be used. Skipping a pre-freeze wash leaves bacteria behind, while washing too soon for fridge storage can cause mould. Following these steps helps keep food safe and extends its shelf life.
