Facts

• Cantaloupes can become contaminated with listeria, but it is typically deli meats and soft cheeses that cause listeria issues in the U.S. When a cantaloupe is infected with listeria, it occurs due to contaminated groundwater or soil where the cantaloupe grows. The listeria is on the exterior rind of the cantaloupe. Listeria can be introduced to the interior flesh of the cantaloupe when the melon is cut or the person preparing the melon doesn't wash his hands before cutting the fruit after touching the exterior.

Risks

• People with compromised immune systems are at high risk for listeria. This includes the elderly, pregnant women or people with various chronic diseases. Newborns can be infected with listeria during birth, but it is rare. The most common way to contract listeriosis is by eating contaminated foods.

Prevention

• When growing cantaloupes at home, have your groundwater and soil tested for listeria monocytogens. Don’t allow animals within the garden because animal feces can contribute to a listeria contamination. Before and after handling a cantaloupe wash your hands in warm, soapy water for a minimum of 20 seconds. Before cutting, scrub the cantaloupe with a produce brush and cool, running water. Between cleanings, sanitize the produce brush to avoid cross-contamination. Refrigerate cut melons at 32 to 34 degrees Fahrenheit and eat them within seven days.

Considerations

• Listeria can be found outside, but it also could be inside your home. According to WebMD, listeria can grow in your fridge after being exposed to the bacteria. Listeria does not alter taste, appearance or texture of your food. If there is a listeria recall, dispose of the foods in your refrigerator that match the recall list and clean your refrigerator thoroughly to kill any bacteria in the fridge.
