Which of the following appliances is commonly used for maintaining food at safe temperatures?

The appliance that is commonly used for maintaining food at safe temperatures is the refrigerator. This appliance is designed to keep perishable foods at a temperature that inhibits the growth of harmful bacteria and pathogens. By storing food at or below 40°F (4°C), a refrigerator effectively slows down the deterioration of food quality and extends its shelf life.

In a food safety context, it is important to maintain these cool temperatures to ensure that food remains safe to consume. The refrigerator plays a critical role in preventing foodborne illnesses caused by harmful microorganisms that thrive at higher temperatures.

Other appliances like a toaster, blender, and microwave serve different functions. While a microwave can be used for cooking and reheating food, it does not maintain temperatures; rather, it can potentially raise food temperatures to unsafe levels if not monitored properly. Similarly, toasters and blenders are used for cooking and preparing food, respectively, but are not equipped for storing food at safe temperatures.
