Even in squeaky-clean environments, produce can become contaminated. Protect yourself (and your favorite people) from becoming sick due to airborne ilnesses, according to the Food and Drug Administration (FDA):
Wash your hands prior to preparing fresh produce.
Cut out and remove damaged or bruised areas of produce.
Rinse produce before peeling to prevent bacteria transfer from the fruit to the knife.
Gently rub produce under warm water to clean it. (Don't use soap or produce wash.)
To clean produce like melons or celery, use a clean vegetable brush or toothbrush.
Dry produce with a clean cloth or paper towel to remove residual bacteria.
Remove the outermost leaves of cabbage or lettuce prior to food prep.
