For years I didn't have a thermometer in my refrigerator, but last year I decided to
purchase one just to be safe. According to the USDA.gov website, 40 degrees or
below is the safest temperature to keep cold foods cold.
Although the freezer in our last refrigerator was still working the refrigerated section
had stopped working properly. I noticed the temperature was up to 45 degrees and
I assumed it was because I had put some warm gallons of water in there, but I was
wrong. The next day it was still 45 degrees, so I knew I was gonna need a new one.
If you don't have a thermometer in your refrigerator you need to get one because it
could save you from a foodborne illness. You can buy a thermometer especially
made for a refrigerator and it's the only way to know if the temperature is safe.
