In California, the meaning of a "sell by" date on food products can vary from person to person. For some, it signifies that the product is no longer good, while for others, it may still be usable. This discrepancy is evident in the household of Kimberley Kausen, a chef, where family members have different interpretations of the date.

The state has taken steps to address the issue of food waste related to these dates. California has banned "sell by" food labels in an effort to reduce waste.
