How to Reduce Your Risk from Listeria: 3 Easy Steps

There are three very simple things you can do to help prevent illness from Listeria:

1. Chill at the Right Temperature.

The right temperatures slow the growth of Listeria. Put a refrigerator thermometer in the refrigerator and adjust the refrigerator temperature control, if necessary. Put a second thermometer in the freezer.

Your refrigerator should register at 40°F (4°C) or below and your freezer at 0°F (-18°C).

2. Use Ready-to-Eat Foods Quickly!

Use ready-to-eat, refrigerated foods by the Use By date on the package. The longer they’re stored in the refrigerator, the more chance Listeria has to grow. 

3. Keep the Refrigerator Clean!

Clean your refrigerator regularly.

Wipe up spills immediately. This is particularly important, so Listeria doesn’t have a place to grow and then spread to other foods.

Clean the inside walls and shelves with hot water and a mild liquid dishwashing detergent, rinse, then dry with a clean cloth or paper towel.
