Not having the proper refrigerator temperature could make you sick.

Why the refrigerator temperature matters

Used correctly, your refrigerator will keep food safe from spoilage and bacteria.

Used incorrectly, it could cause big trouble of the tummy kind.

Essentially, no food benefits from storage. You want to eat everything as fresh as you can.

The refrigerator temperature and food storage guidelines below can help you keep food safe for you and your family.

Cold and Colder

Some parts of your refrigerator are colder than others. The meat compartment at the bottom is designed to store meat - so keep it there.

Not only is this the coldest area, but if the package leaks, it won't contaminate other foods. The door is the warmest part of the refrigerator.

This is the best place for nonperishables (sodas), not perishables (eggs).

Regularly Check the Interior Refrigerator Temperature

You need to have a refrigerator thermometer. Ditto for the freezer temperature, which should be kept at 0 to 5 degrees F.

To keep food from spoiling, the refrigerator temperature needs to be between 34 and 40 degrees F.

You can't depend on the little gauge (1-5) in the refrigerator.

Safe Food Handling Tips

  • Don't put hot food in the refrigerator. Bring it to room temperature before refrigerating it. Hot food can cause the refrigerator temperature to drop.
  • On the other hand, don't leave food out too long either. Refrigerate prepared food within two hours of cooking (one hour in summer).
  • Don't overload the refrigerator. Parties are a dangerous time because you cram a lot of stuff into the refrigerator and then you're continually opening the door, causing the refrigerator temperature to fluctuate greatly. Turn the temperature down during these occasions.
  • Cover foods tightly.
  • Leave meats in their original packaging to prevent spreading bacteria.
  • Don't store breads, cookies, or most cakes in the refrigerator. They will become stale.
  • Tell your family not to stand gazing slack-jawed into the open refrigerator while they decide what they want to eat.
  • If you lose power, do not open your refrigerator or freezer. If the door is not opened, food should keep eight hours in the refrigerator and 48 hours in the freezer.

How Long Food Keeps in the Refrigerator

Refrigerating foods helps keep them fresh, but they still won't last forever. Here are a few examples of how long it's safe to keep some foods.


  • Cooked vegetables
  • Fresh vegetables
  • Poultry, fish, ground meats
  • Other meats
  • Deli meats
  • Hot dogs
  • Milk
  • Sour cream
  • Fresh eggs
  • Condiments

How Long It's Safe

  • 3-4 days
  • 2 to 14 days 
  • 1 to 2 days
  • 3 to 5 day 
  • 5 days
  • 1 week opened; 2 weeks unopened
  • 5 to 7 days
  • 4 weeks
  • 3 weeks
  • 1 to 6 months (opened in the fridge)

Best advice when it comes to your refrigerator and food safety: When in doubt, throw it away. A little thriftiness is not worth a tummy ache. Instead, ensure your refrigerator temperature is within safe limits.
