Proper Refrigerator and Freezer Temperatures
By: Danny Lipford
Since bacteria thrive at temperatures above 40º Fahrenheit (4º Celsius), it’s important to keep your refrigerator set below that level but above freezing for optimum food storage.
Freezers should be set at 0º F (-18º C) or lower. Use an appliance thermometer to check the temperature, allowing 5-8 hours for it to adjust.
