7 Tips for Cleaning Fruits & Vegetables

September 13, 2012 

Federal health officials estimate that nearly 48 million people are sickened by food contaminated with harmful germs each year, and some of the causes might surprise you.

Although most people know animal products must be handled carefully to prevent illness, many don’t realize that produce can also be the culprit in outbreaks of foodborne illness. In recent years, the United States has had several large outbreaks of illness caused by contaminated fruits and vegetables – including spinach, tomatoes and lettuce.

Fresh produce can become contaminated in many ways. During the growing phase, fruits and vegetables may be contaminated by animals, harmful substances in the soil or water, and poor hygiene among workers. After produce is harvested, it passes through many hands, increasing contamination risk. Contamination can even occur after the produce has been purchased, during food preparation, or through inadequate storage.

To avoid illness, you should choose produce that isn’t bruised or damaged, and make sure that pre-cut items – such as bags of lettuce or watermelon slices – are either refrigerated or on ice both in the store and at home. In addition, follow these recommendations:

  • Wash your hands for 20 seconds with warm water and soap before and after preparing fresh produce.
  • Cut away any damaged or bruised areas before preparing or eating.
  • Gently rub produce while holding under plain running water. There’s no need to use soap or a produce wash.
  • Wash produce before you peel it so dirt and bacteria aren’t transferred from the knife onto the fruit or vegetable.
  • Use a clean vegetable brush to scrub firm produce such as melons or cucumbers.
  • Dry produce with a clean cloth or paper towel to further reduce bacteria that may be present.
  • Throw away the outermost leaves of a head of lettuce or cabbage.
  • Store perishable produce in the refrigerator at 40 degrees or below.
