Maintaining a temperature of 4 degrees Celsius (39.2 degrees Fahrenheit) in refrigerated areas is critical for food safety. This temperature limit ensures that perishable foods such as dairy products, meats, and vegetables are kept out of the "danger zone," which ranges from 4 to 60 degrees Celsius (40 to 140 degrees Fahrenheit). In the danger zone, bacteria can multiply rapidly, which increases the risk of foodborne illnesses.

Setting the refrigerator at or below 4 degrees Celsius slows down the growth of harmful microorganisms, thereby extending the shelf life of food and maintaining its quality and safety for consumption. Furthermore, regularly monitoring and adjusting the temperature to meet this standard is a key component of Hazard Analysis Critical Control Point (HACCP) protocols, which aim to systematically prevent food safety hazards.

On the other hand, temperatures significantly higher than 4 degrees Celsius may compromise food safety by encouraging bacterial growth, while a temperature of 0 degrees Celsius is too cold and may cause freezing, which can adversely affect the texture and quality of some foods.
