Which of the following is not part of the header on Form 1090?

The percentage is not a part of the header on Form 1090, which is a critical document used for recording food service operations, particularly within military and government environments. The header typically includes essential information that provides context and clarity about the meal service being documented.

The elements found in the header, such as the date, number of meals, and temperature readings, are vital for understanding the specifics of the meal served on that day. The date records when the meals were provided, the number of meals indicates the volume of service, and the temperature readings ensure that safety standards were met in food handling, which is crucial for food safety and quality assurance.

In contrast, the percentage does not serve a function within the context of the header for Form 1090. It is more likely related to performance metrics or evaluations in different forms or reports, but it is not relevant to the specific data captured on this form. Therefore, its absence solidifies the integrity and purpose of Form 1090 regarding meal tracking and safety compliance.
