Tips from the U.S Food and Drug Administration (FDA) on how to keep produce fresh and free from bacteria -
• Buy fresh rather than old produce.
• Once purchased, refrigerate fruits and vegetables to keep them fresh.
• All produce that is purchased pre-cut or peeled should be refrigerated to maintain both quality and safety.
• Store whole, unpeeled fruits and vegetables in perforated plastic bags, to maintain moisture but allow for air flow to discourage the growth of mold or bacteria
• Do not let fruits and vegetables come into contact with raw meat, poultry, eggs, or the juices of these foods that might be present on a kitchen countertop or the refrigerator.
• Drink only pasteurized milk.
• Wash and dry fruits and vegetables thoroughly before you eat it to remove germs.
• Realize that washing or cooking produce that is already contaminated with salmonella might not eliminate the bacteria. If you have produce that you suspect is contaminated, throw it away.
