What is the correct temperature range for the walk-in freezer inside the restaurant?

The correct temperature range for a walk-in freezer typically must be below 0°F to effectively maintain food safety and quality. Freezers are designed to preserve food by slowing down the growth of bacteria and other microorganisms, which thrive at higher temperatures. When kept at temperatures below 0°F, the freezing process is optimized, ensuring that food remains safe for extended periods while retaining its texture and nutritional value.

In a food service context, such as at a McDonald's restaurant, maintaining proper freezer temperatures is crucial for compliance with food safety regulations and ensuring that customers receive quality meals. A temperature above 0°F, as suggested by some alternative choices, may lead to compromised food safety, risking spoilage and potential foodborne illnesses. Thus, the requirement for walk-in freezers to operate below 0°F is essential for effective food storage and safety practices.
