What's happened
California has begun enforcing a new labeling regime to replace consumer-facing “sell by” dates with two standardized labels: “Best if Used By” for quality and “Use By” for safety. The change, aimed at reducing household food waste and emissions, follows similar moves in New York and inches toward a possible national standard. Some retailers are updating packaging, while old labels may persist during the transition.
What's behind the headline?
From Patchwork to Standard
- California’s move consolidates 50+ date terms into two core labels, cutting shopper confusion.
- This shift may influence national discussion and spur federal consideration, given the bipartisan push in Congress.
- The law’s impact hinges on retailer compliance and the speed of transition from old stock.
Economic and Environmental stakes
- Reducing food waste aligns with emissions goals, given California’s large waste footprint.
- Grocers anticipate a win-win: simpler labeling could lower waste and streamline shelf management, even as some transition costs loom.
Public behavior and information gaps
- Consumer misunderstandings around date labels drive waste; standardization seeks to restore trust and clarity in food safety signals.
How we got here
The state passed a 2024 law to standardize date labels, making California the first to implement beyond pilot programs. New York has approved a similar measure awaiting governor’s signature. Federal regulation remains limited to infant formula, leaving a patchwork of state actions to reduce food waste and confusion around date labels.
