Do you have an older slow cooker? Are you wondering if it is still safe to use? Here is an easy test.
To determine if a slow cooker is safe to use: Fill the slow cooker one-half to two-thirds full of tap water. Heat on a low setting for 8 hours with the lid on. Check the water temperature with an accurate food thermometer. Do this quickly because the temperature drops 10 – 15 degrees when the lid is raised or removed. The temperature of the water should be 185°F. Temperatures below 185°F would indicate the slow cooker does not heat food high enough or fast enough to avoid potential food safety problems; the slow cooker is unsafe and should be replaced.
