Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C).
The recommended freezer temperature to keep food safe is at or below 0°F (-18°C), making higher temperatures less reliable for long-term freezer storage. However, freezer temperatures may need to be adjusted by a few degrees to account for factors like location, humidity or outside temperatures.
A freezer, according to food safety standards, should be anywhere between -10°F & 10°F. Anything under can risk freezer burn, and anything over can risk bacteria growth.
What is the ideal temperature for your freezer? It's probably no surprise that you want your freezer to be set to freezing. The ideal temperature for your freezer is 0 degrees Fahrenheit, but -10 to -20 degrees Fahrenheit should be fine.
Food can still be frozen when the freezer is set warmer than -18°C. In fact, food will begin to freeze at 0°C (the well-known freezing point). However, food that's kept frozen between 0°C and -17°C will sacrifice safety and quality. The colder the temperature of your freezer, the safer it is.
The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
Avoiding Freezer Burn
The ideal temperature for a commercial freezer is between 0°F / -18°C and -20°F / -29°C. If the temperature in your freezer fluctuates, it will cause ice crystals to form on your food. These ice crystals will dry out your food and cause freezer burn.
It illustrates that any food with an internal temperature of 40 °F to 140°F is in the temperature danger zone. Refrigerator temperature should be at or below 40 °F and freezer temperature should be zero degrees.
Frost or ice build-up on freezer walls can be one of the signs your freezer is too cold. First, check the temperature setting to make sure it's within a degree of 0ºF (-18ºC) and adjust accordingly. If you notice ice crystals on frozen food, these items may be freezer burned due to colder or fluctuating temps.
However, if your freezer is cold but not freezing, it may be time to inspect the thermostat. Try changing the thermostat from the lowest setting to the highest setting. If you don't hear a click sound, then a professional replacement is recommended.
The ideal temperature for freezing meat is between -18 and -23 degrees Celsius (0 to -9 degrees Fahrenheit), as recommended by the United States Department of Agriculture (USDA) for safe and optimal storage. At 20 degrees Fahrenheit, the meat will not be at a safe temperature for storage.
Leave the freezer door closed. Frozen foods that have reached temperatures of 40 °F and above for more than two hours are not safe to eat. Discard these items.
But whatever you put into your fridge carries lurking microbes that, if left in the wrong environment, can cause bad fridge smells and bacteria. So what temperature is the right temperature? The Food Standards Agency advises household fridges to be set at 5 degrees Celsius or below.
Is It OK for Your Freezer To Be Set at 10 Degrees? Setting your freezer to 10 degrees Fahrenheit is generally not recommended for long-term food storage. Food stored at this temperature is at a higher risk of spoilage and freezer burn, as well as the growth of bacteria and other pathogens.
If your freezer is not cold, the problem may be caused by a broken condenser fan motor. The condenser fan draws cool air through the condenser and over your freezer's coils. If this fan is broken, your freezer's inner temperature will rise, and the compressor will overheat.
If foods still contain ice crystals and/ or if the freezer is 40 degrees F or less and has been at that temperature no longer than one to two days, then food that was safe when it was originally frozen should be safe now. It can be refrozen or cooked and eaten.
According to the Food and Drug Administration FDA the best freezer temperature is 0 ° Fahrenheit or -18 ° Celsius which is sufficient to keep the food safe for an extended period of time.
You'll know your freezer is set too cold (or malfunctioning) when you start to notice more freezer burn than usual on food. A little bit of freezer burn is normal and perfectly safe to eat, but it can still negatively affect the taste and quality of the food.
The ideal temperature for most household freezers is 0°F (-18°C) or lower. At this temperature, food can be safely stored for an extended period without compromising its quality.
Freeze occurs when the temperature drops to 32°-or-lower. A freeze will damage many unprotected plants, especially if the temperature remains at-or-below freezing for several hours.
Keep Food Out of the "Danger Zone"
If the temperature is above 90 °F, food should not be left out more than 1 hour. Keep hot food hot—at or above 140 °F. Place cooked food in chafing dishes, preheated steam tables, warming trays, and/or slow cookers. Keep cold food cold—at or below 40 °F.
Freezer - Refrigerator Temperatures
Eat those foods as soon as possible for best quality. Use a free-standing freezer set at 0 °F or below for long-term storage of frozen foods. Keep an appliance thermometer in your freezing compartment or freezer to check the temperature.
However, if your freezer is running too cold or there's a fluctuation in temperature, this may cause freezer burn. Check for ice crystals on the outside of food. While food with freezer burn is usually safe to eat, the food's flavor and texture may be compromised.
Whilst it is recommended to keep your freezer below -18 degrees Celsius, it is important to not drop the temperature too low. Although 4-star freezers can operate down to -25°C, over time foods frozen at this temperature may start to dry out, causing freezer burn or a loss in quality.
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.
