What temperature range is typical for refrigeration in food preservation?

The temperature range of 34 to 40 degrees Fahrenheit is considered ideal for refrigeration in food preservation. This range effectively slows down the growth of bacteria and other pathogens that can spoil food and lead to foodborne illnesses. Keeping food at this temperature ensures that perishable items, such as dairy products, meats, and vegetables, remain safe for consumption while maximizing their freshness and shelf life.

Storing food below 34 degrees can lead to freezing, which may compromise the texture and quality of certain items. Conversely, temperatures above 40 degrees increase the risk of rapid bacterial growth, making food unsafe for consumption. Thus, maintaining the temperature within the specified range is critical for food safety and quality in a refrigeration environment.
