When is food in unmarked containers supposed to be discarded?

Food in unmarked containers should be discarded whenever there is no label because labels provide essential information regarding food safety, including the contents, date of preparation, and storage instructions. Without a label, there is a risk of the food being spoiled, contaminated, or unsafe to consume, which could lead to foodborne illnesses. Establishing a clear labeling system helps ensure proper food handling and storage, allowing for better tracking of food freshness and safety. Thus, the absence of a label creates uncertainty about the food's safety and quality, making it necessary to discard that food to protect public health.
