If washing apples or lettuce sends you searching for a vinegar or baking-soda ratio, first check the produce and its packaging. Loose produce and a package labeled pre-washed and ready to eat need different checks.
Check the label before you wash
Products labeled pre-washed and ready to eat do not need washing again. If you choose to rewash them, use clean tools. Washing cannot remove all microorganisms. FDA
Words such as “salad,” “fresh,” or “organic” in a product name do not tell you how to prepare it. Look for the original package or ask the manufacturer. Whether frozen vegetables need cooking is a separate question.
Match washing to the surface
- Wash hands, trim bruised areas, and discard rotten produce.
- Gently rub under running water before peeling or cutting.
- Use a clean produce brush for firm surfaces such as melons or cucumbers, then dry with a clean cloth or paper towel.
FDA fruit and vegetable cleaning tips
Before applying a vinegar or baking-soda recipe
“How much of a particular pesticide was removed?” is different from “Is this food safe to eat?” A test on one substance and crop, using a particular concentration and soaking time, cannot tell us how every kitchen mixture will work. That is why this guide does not give a homemade mixture ratio or promise to remove every trace of residue.
Start with the package instructions and the preparation steps below. Whether a country permits a cleaning product and whether a health authority recommends it for home use are separate questions. The running-water advice here comes from the US FDA’s consumer guidance.
Set out a clean bowl before washing
Keep equipment used for raw meat separate, and refrigerate produce that is sold pre-cut and chilled. FDA
