Why must the pasteurizer temperature recording chart not read higher than the indicating thermometer?

The pasteurizer temperature recording chart must not indicate a higher temperature than the actual product temperature to ensure the integrity and accuracy of the pasteurization process. If the chart records a temperature higher than what the indicating thermometer shows, it can lead to a false sense of security regarding the effectiveness of the pasteurization. This could result in underpasteurization, which poses a significant risk to food safety, as harmful pathogens may survive.

This principle is critical for maintaining public health standards and ensuring that products are effectively pasteurized to eliminate or reduce harmful microorganisms. Accurate temperature recording is essential for compliance with safety regulations, as it serves as documentation that the pasteurization process met the required standards. Therefore, maintaining the accuracy of recorded temperatures directly impacts both food safety and regulatory compliance.
