Question

Why does the state department put an expiration date on milk and meats?​

Answer 1

The term Use by is often applied to products such as milk and meat that are more likely to spoil and can become dangerous to those eating them. ... In these contexts, the expiration date is chosen for business reasons or to provide some security function rather than any product safety concern.

Answer 2

Answer: To reduce consumer confusion and wasted food, FSIS recommends that food manufacturers and retailers that apply product dating use a “Best if Used By” date. Research shows that this phrase conveys to consumers that the product will be of the best quality if used by the calendar date shown.
