Which of the following MUST be posted in a food facility?

In a food facility, it is essential to post grade cards, which reflect the inspection results conducted by health authorities. These cards display the hygiene and safety standards met by the establishment and inform customers about the facility's compliance with food safety regulations. Having grade cards visibly posted promotes transparency and encourages establishments to maintain high standards, as patrons can see the results of health inspections before deciding to dine there.

While menu specials, employee schedules, and cooking times may be useful for internal management and customer service, they are not mandated by health regulations to be posted publicly. Posting grade cards, however, is a requirement that serves a critical role in ensuring public health and safety.
