Commercial Freezer Temperatures: Keeping Your Food Safe

Last updated: February 1st, 2024
Commercial freezers need to be reliable when it comes to temperatures. Whether you are running a restaurant or a supermarket, or even storing chemicals and medical supplies, you need to know you can adequately control temperatures.
Commercial freezers typically maintain a temperature of -10 to 0 degrees Fahrenheit. To us in the UK, that means -23 to -18 degrees Celsius. This temperature range is ideal for preserving frozen foods and preventing the growth of bacteria that can spoil or compromise the quality of the products. It’s important to monitor and regulate the temperature regularly to ensure the proper storage of frozen goods.
The Importance of Maintaining Correct Commercial Freezer Temperatures
Frozen food should never be allowed to thaw before refreezing. In the food supply line, it is crucial to ensure that the food is kept cold at all times, this means reliable commercial freezer equipment, and even freezer transport.
Allowing food to defrost and then refreezing it can pose several risks to food safety and quality. When food is initially frozen, ice crystals form within the cells of the food. If the food is allowed to thaw and is then refrozen, these ice crystals can rupture cell walls, leading to changes in texture, flavour, and nutritional content. Here are some specific risks associated with letting food defrost and refreezing:
- Microbial Growth: During the thawing process, bacteria, and other microorganisms can multiply at a faster rate as the temperature rises. If the food is then refrozen without proper cooking, these microorganisms may survive and pose a risk of food borne illness.
- Texture and Quality Changes: The process of freezing and thawing alters the structure of food, potentially resulting in changes to its texture and quality. This can lead to a less appealing taste and appearance.
- Moisture Loss: Thawing and refreezing can cause moisture loss in the food, leading to dryness and loss of juiciness. This is particularly noticeable in meats and certain fruits and vegetables.
Of course, the health hazards and potential risks of bacteria growth are the most important of the problems that can occur. If you are serving food to the public, you have a duty to ensure that food is stored correctly.
The guidance from the from the Food Standards Agency is as Follows:
“Ensure your fridges and freezers are set to the recommended temperatures. Fridges and chilled display equipment should be set at 8˚C or below as a legal requirement. A freezer should be -18°C.”
Keeping Your Freezers At a Safe Temperature
Ensuring that your commercial freezer temperatures are stable and that it is operating effectively is crucial for preserving the quality and safety of the stored food. Here are some steps to help you monitor and maintain the correct temperature:
- Place a reliable and accurate thermometer inside the freezer to regularly monitor the temperature. Ensure that the thermometer is located in the warmest part of the freezer to provide an accurate representation of the overall temperature.
- Regularly calibrate the thermometer to make sure it provides accurate readings. Follow the manufacturer’s instructions for calibration, and adjust the thermometer if necessary.
- Check the settings. Review the temperature settings on the freezer’s control panel. Make sure they are set within the recommended range for frozen food storage.
- Don’t overload your freezer. Overloading the freezer can hinder proper air circulation and lead to uneven temperature distribution. Avoid overcrowding to maintain consistent cooling.
- Inspect the gaskets and seals on the freezer doors regularly to ensure they are in good condition.Replace any damaged or worn-out seals promptly to prevent cold air leaks. This is where you may need freezer repair or servicing.
- Emergency power. Install emergency power backup systems, such as a generator or uninterruptible power supply (UPS), to prevent temperature fluctuations during power outages.
