However, the storage conditions of frozen meat may be just as important as the freezing rate and, perhaps more important, in determining the ultimate quality of frozen meat. Meat starts to freeze at 26-28 degrees F, but traditionally has been considered to be frozen when the core temperature reaches 0 degrees.
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.
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.
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.
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.
Freeze Fresh Eats
A freezer or refrigerator is not a time machine. If you freeze ground beef that is about to go bad, chances are you'll have rotten meat when it is thawed. Freeze fresh meat for the best outcomes, not those about to spoil. The sooner they go into the freezer, the fresher they come out.
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.
You can always err on the safe side and lower the temperature below 0°F—your freezer can never be too cold. “Most recommendations are for a range of temperatures but in reality, there is no temperature that is too low for freezers,” says Tetro. “Most freezers do have a lower limit of around -10°F (-23°C).”

It can be refrozen or cooked and eaten. If food has been held at 40 degrees For less but kept at this temperature for some time, examine it more closely. If the color or odor of thawed beef, pork, lamb or poultry are poor or questionable, discard the meat away from possible human or animal consumption.
In very cold temperatures the compressor lubricating oil becomes too viscous and the compressor can't start because of excess friction. This causes the compressor overcurrent protector to trip. If the freezer is left ON in a cold place, it will keep trying to start over and over again.
The refrigerator temperature should remain under 40 degrees in all sections. Don't leave perishable foods out of refrigeration for more than two hours.
The ideal temperature for your freezer is 0 degrees Fahrenheit, but -10 to -20 degrees Fahrenheit should be fine. If the temperature is any lower, or if it's a little low and you want to get it just right, try moving the gauge to 0 degrees and check again in 24 hours after it has had time to adjust.
Frozen meat remains safe to eat as long as it has been frozen, however the quality and taste may not be the same. Frozen meat may no longer be fresh if it is discolored or has freezer burn on it or if it has developed a strong odor.
When is it safe to refreeze food? You can safely refreeze frozen food that has thawed—raw or cooked, although there may be a loss of quality due to the moisture lost through thawing. To safely refreeze, the thawed product must have been kept cold at 40 degrees or below for no more than 3-4 days.
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.
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.
The FDA specifies that meats be stored at 0° F (-18° C) or below, seafood at -1° F (-18° C), and poultry at -2° F (-19° C). Meanwhile, set the refrigerator temperature at or below 40° F (4° C) to keep the vegetable and fruit fresh.
A blocked evaporator fan
When your freezer is cold but not freezing, the problem could be the fan. The evaporator fan moves cold air throughout the freezer. If ice buildup or other obstructions block the fan, it can't circulate air effectively, leading to cooling issues.
When thawing frozen food, it's best to plan ahead and thaw in the refrigerator where it will remain at a safe, constant temperature — at 40 °F or below. There are three safe ways to thaw food: in the refrigerator, in cold water, and in the microwave. In a hurry? It's safe to cook foods from the frozen state.
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.
All deli meats can be frozen. Cured meats, like sausage, bologna and bacon, tend to hold up the best, thanks to their dense, hearty texture and lower water content. Freezing roasted turkey, ham, chicken and other deli meats is still possible, but the meat may be slightly wet upon defrosting.
Per FSIS-USDA guidelines, if kept frozen continuously, chicken will be safe indefinitely, so after freezing, it's not important if any package dates expire.
According to USDA Food Safety and Inspection Service Guidelines, when you properly store food, including meat, at 0 degrees Fahrenheit, it remains safe to consume indefinitely. Freezing is a safety net that preserves food by slowing molecular movement and activity.
