What characteristic indicates that eggs, milk, and milk products should be deemed unsatisfactory?

The most suitable characteristic to indicate that eggs, milk, and milk products are unsatisfactory is a high temperature. These perishable items need to be kept at a specific temperature to ensure their safety and quality. If eggs, milk, or dairy products are stored at a temperature that's too high, it can lead to the growth of harmful bacteria, spoilage, and a potential risk of foodborne illness. Monitoring storage temperatures is essential in food service to maintain food safety standards.

While other factors, such as an unpleasant smell or non-uniform color, may suggest that these items are no longer good, they can sometimes be subjective and may not always be reliable indicators of spoilage. An expired date stamp is also crucial, but it pertains more to quality and usability rather than immediate safety concerns. In contrast, a high temperature is an objective, measurable factor that directly impacts food safety.
