Anything above the USDA-recommended 0 degrees Fahrenheit (-18 degrees Celsius) is not ideal. At 7 degrees Fahrenheit, the food inside the freezer will not be at a safe temperature for storage and may be at risk for bacterial growth, spoilage, and foodborne illness.
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.
While -18°C is the ideal, a freezer can still function effectively within a small range. The appropriate freezer temperature range is generally between -16°C to -22°C (3°F to -7°F).
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.
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.
Fresh steak: store at an internal temperature of 41˚F (5˚C) or lower. 2. Fresh chicken: store at an internal temperature of 41˚F (5˚C) or lower.
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.

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.
Keeping food in the freezer
Your freezer should be around -18°C. For safety, it's ok to freeze most raw or cooked foods providing you do the following things: freeze food up until the 'use by' date. follow any freezing or defrosting instructions on the label.
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.
Preventing freezer burn is a priority, but that doesn't mean you should risk food spoilage. Whenever you freeze food, make sure that your freezer is set to the proper temperature – zero or below and get to know the parts of your freezer to be able to troubleshoot any problems.
Food that is properly handled and stored in the freezer at 0° F (-18° C) will remain safe.
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.
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.
The short time limits for home-refrigerated foods will help keep them from spoiling or becoming dangerous to eat. The guidelines for freezer storage are for quality only—frozen foods stored continuously at 0°F (-18°C) or below can be kept indefinitely.
Any temperature above -18 degrees Celsius (0 degrees Fahrenheit) is considered too high for a freezer. At temperatures above this, bacteria and other microorganisms can begin to grow and multiply, potentially leading to food spoilage and foodborne illnesses.
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.
"Danger Zone" (40°F - 140°F) Leaving food out too long at room temperature can cause bacteria (such as Staphylococcus aureus, Salmonella Enteritidis, Escherichia coli O157:H7, and Campylobacter) to grow to dangerous levels that can cause illness.
A Freeze Warning is issued when temperatures are forecasted to go below 32°F for a long period of time. This temperature threshold kills some types of commercial crops and residential plants, while temperatures below 28°F for an extended period of time can kill most types of commercial crops and residential plants.
When preparing, cooking, storing and reheating food, remember that the danger zone is 40°F to 140°F. If you are cooking hot food, keep the food at 140°F or higher. If you are not serving food immediately, it's important to continue maintaining this temperature to prevent bacteria growth.
The freezing process usually takes place between 0°C and -5°C. This zone, called the critical zone or the zone of maximum crystallization, must be passed quickly. In fact, the freezing point is not the only point.
The ideal freezer temperature
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.
Frozen Food and Power Outages: When to Save It and When to Throw It Out. A full freezer will hold a safe temperature for approximately 48 hours (24 hours if it is half full and the door remains closed).
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.
