The refrigerator and freezer are two other storage facilities used to lengthen the shelf life of food. To have them work best, make sure your refrigerator is at about 38 or 39°F. You can place thermometers in your refrigerator to check. If they’re higher than 40°F, then a certified maintenance person should be called to fix it.
Other guidelines for your fridge to maintain the proper temperature: Don’t overpack it and or line the shelves with aluminum foil or other types of paper. This will decrease the airflow in the refrigerator and can lead to an unwanted increase in the refrigerator’s temperature. Lastly, don’t place hot food in your refrigerator which can raise the temperature of all other foods in there, which may cause them to spoil sooner.
Your freezer should be maintained around 0°F in order to keep your food frozen. If you have large ice crystals, it’s time to give it a good defrosting and cleaning.
