The short answer is no, 20 degrees is not OK for a freezer. The ideal temperature for a freezer is 0°F or below, according to the FDA. Keeping your freezer at this temperature will ensure food safety and quality, as well as energy efficiency. In this article, we will explain why 20 degrees is too high for a freezer, how to measure and adjust your freezer temperature, and what are the benefits of maintaining the optimal freezer temperature.
Freezing food is a great way to preserve it for a long time, as it slows down the growth of bacteria and other microorganisms that can cause spoilage and foodborne illnesses. However, not all freezing temperatures are equally effective. The lower the temperature, the better the freezing process.
At 20 degrees, your freezer is not cold enough to freeze food properly. Food that is stored at this temperature may develop ice crystals, lose moisture and flavor, and become susceptible to bacterial growth. This can affect the taste, texture, and safety of your food. Moreover, food that is not frozen solid may thaw and refreeze repeatedly, which can further damage its quality and increase the risk of contamination.
According to the USDA, food that is stored at 0°F or below can last indefinitely, as long as it is properly packaged and handled. However, food that is stored at higher temperatures may lose its quality and safety over time. For example, ground beef that is stored at 0°F can last for 3 to 4 months, but at 20°F it may only last for 1 to 2 months. Similarly, ice cream that is stored at 0°F can last for 2 to 4 months, but at 20°F it may only last for a few weeks.
How to Measure and Adjust Your Freezer Temperature
To measure your freezer temperature, you can use a freezer thermometer, which is a device that can withstand low temperatures and display accurate readings. You can place the thermometer in the center of the freezer, away from the walls and the door, and check it after 24 hours. If the temperature is higher than 0°F, you need to adjust it.
To adjust your freezer temperature, you can use the thermostat that is usually located inside the freezer or on the control panel. Depending on the model of your freezer, you may have to turn a dial, press a button, or use a digital display to change the temperature settings. You can refer to the owner’s manual for specific instructions on how to do this.
After adjusting your freezer temperature, you should wait for another 24 hours and check the thermometer again. If the temperature is still higher than 0°F, you may need to adjust it further or contact a professional for repair. You should also check your freezer temperature regularly, at least once a month, to make sure it is consistent and stable.
What Are the Benefits of Maintaining the Optimal Freezer Temperature
Keeping your freezer at 0°F or below has many benefits, such as:
Preserving the quality and safety of your food. Freezing food at the optimal temperature will prevent bacterial growth, ice crystals, moisture loss, and flavor changes. Your food will retain its freshness, color, texture, and nutritional value for a longer time.
Saving money and reducing food waste. Freezing food at the optimal temperature will extend its shelf life and allow you to store it for a long time. You can buy food in bulk, take advantage of sales, and plan your meals ahead. You can also avoid throwing away food that has gone bad or lost its quality.
Improving energy efficiency and environmental impact. Freezing food at the optimal temperature will reduce the amount of energy that your freezer consumes and the amount of greenhouse gases that it emits. According to Energy Star, a freezer that is set at 0°F uses about 10% less energy than a freezer that is set at 10°F. This can save you money on your electricity bill and help protect the environment.
In conclusion, 20 degrees is not OK for a freezer. The ideal temperature for a freezer is 0°F or below, as recommended by the FDA. Keeping your freezer at this temperature will ensure food safety and quality, as well as energy efficiency. To measure and adjust your freezer temperature, you can use a freezer thermometer and a thermostat. To enjoy the benefits of maintaining the optimal freezer temperature, you can preserve, store, and consume your food properly.
