Here is another tip for safeguarding food at home. Take care that you set the temperature of your refrigerator at or below 40 degrees F and your freezer below 0 degrees F for appropriate food storage.
As you know, the favorable temperature for bacteria to thrive is between 40°F and 140°F. When the temperature is below 40°F the bacteria find it difficult to grow. You can also buy an appliance thermometer that is available in the kitchen utensils department of any grocery store for this purpose.
Place this thermometer in the refrigerator and the freezer to monitor temperatures at both these places.
