A safe slow cooker, cooks slow enough for unattended cooking, yet fast enough to keep food out of the bacterial danger zone. In the danger zone (above 40°F to below 140°F), bacteria grows very rapidly. Food left in the danger zone too long can cause food borne illness.

The general rule of thumb is that 2-4 hours is the maximum length of time you can leave food in a slow cooker on warm. After this, it needs to be cooled and transferred into the refrigerator.

The direct heat from the pot, lengthy cooking and steam created within the tightly-covered container combine to destroy bacteria and make the slow cooker a safe process for cooking foods.
