Here's the Right Temperature for Your Refrigerator and Freezer (Because a Few Degrees Makes a Departure)
Keeping foods chilled properly helps them last longer and stay fresher. Sticking to the ideal refrigerator temps tin can help you lot avoid potential foodborne illnesses, too.
The refrigerator is a miracle of modern nutrient preservation. At the correct refrigerator temperature, the apparatus tin can keep foods common cold and safe to consume for days or weeks by slowing the growth of bacteria. Alternatively, freezers can keep foods fresh and deter bacterial growth for months—or sometimes fifty-fifty indefinitely.
When food temps begin to climb above a sure point, leaner start to multiply exponentially. Not every one of those bacteria is bad—but not every germ is good, either. For both the quality of your food and to reduce the risk of nutrient poisoning, y'all'd be wise to keep your fridge cooled to the recommended temperature and follow skillful refrigerator maintenance guidelines.
What Temperature Should a Fridge Exist?
The U.S. Food and Drug Administration (FDA) recommends that yous keep your fridge temperature at or below 40°F and your freezer temperature at or below 0°F. However, the ideal refrigerator temperature is actually lower. Aim to stay between 35° and 38°F (or 1.7 to 3.3°C). This temperature range is equally close as you tin get to freezing without being so cold that your food will freeze. It's also as close as the refrigerator temperature should get to the twoscore°F threshold, at which point bacteria begin multiplying rapidly.
Temperatures above the 35° to 38°F zone may be too high, peculiarly if your fridge's born temperate gauge is inaccurate. Your food may spoil quickly, and you could set up yourself up for some tum troubles with bacteria, such as Salmonella and E. coli.
What Temperature Should a Freezer Be?
By and large, information technology would be best to continue a freezer as close to 0°F as possible, except when yous're adding a lot of new, warmer food. Some freezers have an option for a flash freeze, which will drib the freezer'south temperatures for 24 hours to avert freezer fire from the temperature variation. Y'all can opt to subtract the freezer temp manually for a few hours, but don't forget to modify information technology dorsum after. Keeping your freezer at a likewise cold temperature tin sew together your utility bill and cause food to lose moisture and flavor. If the freezer has a lot of congenital-up ice, that's a certain sign that your freezer temp is as well cold.

How to Measure an Authentic Temperature
Unfortunately, non all fridge temp gauges are accurate. You may have your fridge set to 37°F, but it's really keeping temps around 33°F or fifty-fifty 41°F. It'due south not uncommon for refrigerators to be a few degrees off the mark yous set up.
What'south more, some refrigerators don't display temps at all. They allow you adjust the fridge temps on a scale of i to 5, with 5 existence the warmest option. Without a thermometer, you can't know what those milestones translate to in real degrees.
You can purchase an cheap freestanding apparatus thermometer online or at any habitation store. Identify the thermometer in your fridge or freezer and leave it for 20 minutes. Then cheque the reading. Are you close to the ideal temperature, or even the recommended ane?
If not, adjust the fridge temperature appropriately to keep the temps in the rubber zone between 35° and 38°F by using the fridge's temperature control console. You can do the same in your freezer, aiming to get the temp every bit close to 0°F as possible.
How to Keep Your Fridge and Freezer Absurd
If you find your fridge temperature is flirting with the 40°F mark or your freezer is too warm despite your adapted temperature settings, you can take a few steps to help maintain an ideal temperature.
Allow food cool earlier storing it.
Hot bowls of leftover soup or roast chicken tin can heat up the small space in your fridge or freezer quickly, putting the foods at jeopardy of rapid bacterial growth. To protect everything inside, let foods cool for a scrap (but not to room temperature—that will take too long) before covering and storing.
Cheque the door seals.
Gaskets around the edge of a refrigerator door keep the common cold temps in and the warmer temps out. If there's a leak in one of those gaskets, your cold air may be escaping. That can make cooling the appliance properly more than hard (and apply up more than electricity, boosting your monthly electrical bill).
Stop opening the door then much.
Every time you open the refrigerator door, y'all let the common cold air out and the warm air in. Resist the temptation to stand at your fridge when y'all're hungry, searching for a nutrient that volition cure your cravings. Instead, get what y'all came for, and shut the door quickly.
Keep the fridge and freezer full.
A total fridge is a happy refrigerator. The same is true for your freezer. The fridge temperature can stay libation longer and keep foods cooled all-time if the shelves and drawers are generally total. Just be sure you don't overcrowd the space and cutting downwardly on air flow. That can make moving cooled air difficult and increase the risk of warm pockets of air. Ideally, exit around twenty pct of the space open. (A fiddling refrigerator organization can help with that, also.)
