The U.S. Food and Drug Administration (FDA) recommends that your refrigerator temperature should be 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).
Your refrigerator should be set at or below 40°F (4°C) to keep food safe and prevent bacterial growth. Ideally, the temperature for the refrigerator is around 37°F (3°C). For the freezer, the temperature should be 0°F (-18°C) or lower.
The ideal refrigerator temperature is about 37°F (3°C). However, a range of 33–40°F (0–4°C) is generally accepted as safe for most purposes. Temperatures below 33°F may freeze foods while temperatures above 40°F may lead to food spoilage.
Chilling foods to proper temperatures is one of the best ways to slow the growth of these bacteria. To ensure that your refrigerator is doing its job, it's important to keep its temperature at 40 °F or below; the freezer should be at 0 °F.

Yep: A fridge temperature of 37° F will keep fresh food good for as long as possible—with no ice crystals on lettuce or bacteria breeding in raw meats. As for the freezer, a temperature of 0° F will keep foods thoroughly frozen.
For the fridge compartment, we recommend maintaining a temperature between 3°C to 5°C to slow bacterial growth and preserve perishable items effectively. Similarly, for the freezer compartment, it is best to set the temperature at -18°C or lower to freeze food solid and maintain its quality over longer periods.
Door seals are one thing, but proper temperature settings are key to keeping your food fresh and your fridge efficient during summer. So it's best to make sure the internal temps are working like they need to! Check the Thermostat: Ensure the fridge thermostat is set between 35°F and 38°F for optimal cooling.
The longer they're stored in the refrigerator, the more chance Listeria, a bacterium that causes foodborne illness, can grow, especially if the refrigerator temperature is above 40° F (4° C). Be alert for spoiled food. Anything that looks or smells suspicious should be thrown out.
By law, Grade A milk must be maintained at a temperature of 45 °F or below. Bacteria in milk will grow minimally below 45 °F. However, temperatures well below 40 °F are necessary to protect the milk's quality.
To reduce Salmonella growth, eggs gathered from laying hens should be refrigerated as soon as possible. After eggs are refrigerated, they need to stay that way. A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg.
The Department of Agriculture states bacteria multiply quickly in the "Danger Zone," which is temperatures beginning at 40°F (4.5°C). It's best to set your temperature gauge a few degrees below that. Most experts recommend that the ideal temperature setting for a refrigerator is between 35-38°F (1.6-3.3°C).
The ThermoWorks Fridge/Freezer Thermometer is the best overall fridge thermometer because it's a reliable and versatile option. The magnetic thermometer is highly accurate and can be used in both sections of your appliance—or even in a deep freezer.
You should keep your fridge temperature set at 3°C/37.4F and your freezer set at -19°C/-2.2F (or -18°C/-0.4F, depending on your model) all year-round.
If it's set too cold, set it higher and give it a day to adjust. Be sure to only adjust the temperature in relatively low increments, checking with a thermometer every 24 hours.
1. Store raw food like meat, poultry, fish, sausages, bacon etc., in the bottom part of the fridge so that juices cannot drip on foods below. 2. Store ready-to-eat foods such as cooked meats, pies and dairy products such as cheese, butter, cream and yoghurt in the top part of the fridge.
But if your refrigerator seems to be “running” all the time, then the appliance is working too hard. While having a refrigerator that works overtime might give the impression the appliance is especially robust, it's actually an indication that something could be wrong with your refrigerator parts.
Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature. The refrigerator will keep food cold for about 4 hours if it is unopened. A full freezer will keep the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.
Never leave cooked eggs or egg dishes out of the refrigerator for more than 2 hours or for more than 1 hour when temperatures are above 90° F. Bacteria that can cause illness grow quickly at warm temperatures (between 40° F and 140° F).
Aim to stay between 35° and 38°F (or 1.7 to 3.3°C).
