In central kitchens, how accurate must thermometers be within refrigerators and freezers?

The accuracy of thermometers in central kitchens, particularly within refrigerators and freezers, is crucial for ensuring food safety. The correct choice indicates that thermometers must be accurate to within 3 degrees Fahrenheit.

This level of accuracy is essential because it helps maintain safe temperatures for food storage, preventing spoilage and reducing the risk of foodborne illnesses. The U.S. Food and Drug Administration (FDA) recommends that refrigerators be kept at 40 degrees Fahrenheit or below, and freezers at 0 degrees Fahrenheit or below. If the thermometer’s accuracy is greater than 3 degrees, it could lead to misinterpretation of the temperature, resulting in unsafe food conditions.

The 3-degree accuracy also allows for some variability due to the nature of how temperatures can fluctuate in different locations within the refrigeration units. By adhering to this level of precision, food service establishments can better manage their food safety protocols, ensuring that all food items are kept at a safe temperature for consumers.
