What is the recommended storage temperature range for a refrigerator?

The recommended storage temperature range for a refrigerator is 34 to 40 degrees Fahrenheit because this range effectively slows down the growth of bacteria and other pathogens in food. Maintaining a temperature within this range ensures that perishable items, such as dairy products, meats, and vegetables, stay fresh and safe for consumption.

Storing food at temperatures lower than this range, such as 30 to 32 degrees Fahrenheit, might cause some items to freeze, which can negatively affect their texture and flavor. On the other end, temperatures above 40 degrees Fahrenheit increase the risk of foodborne illnesses, as bacteria can multiply rapidly.

Thus, the specified range not only preserves the quality of food but also plays a crucial role in food safety, making it vital for any food service establishment, including McDonald's, to adhere to these guidelines.
