Store fruits and vegetables in the refrigerator. Bacteria that is present on fruits and vegetables is likely to thrive at room temperatures. Scrub and rinse each piece of product carefully, especially if you intend to eat it raw. Although this will not kill bacteria, it will reduce the numbers. Do not wash foods in soapy water because the soap can leave residues of its own.
Rinse lettuce leaves individually under cool tap water.
You may want to peel away and toss the very outside layer of leafy produce. Scrub root vegetables, even if you plan on peeling them later. Rinse delicate fruit, such as berries in a colander. Remove the leafy stems as they often harbor bacteria. Rinse sprouts and fresh herbs before serving.
