Which food product date-labeling phrase always relates to food safety?

The phrase that always relates to food safety is the expiration date. This labeling indicates the last day that a food item is considered safe to consume. After this date, the food may deteriorate in quality or safety, and it should not be eaten. It serves as a clear guideline for consumers, ensuring they are aware of the potential risks associated with consuming the product past that date.

The other labeling phrases, such as freshness dates, best if used by/before dates, and sell by dates, mainly focus on quality rather than safety. While these dates can indicate the optimal time for consumption for the best taste and experience, they do not carry the same level of safety implication as the expiration date does. Thus, understanding the significance of these labels is key for responsible food consumption and safety practices.
