On Wednesday, the Food Marketing Institute and the Grocery Manufacturers Association, the two largest trade groups for the grocery industry, announced that they’ve adopted standardized, voluntary regulations to clear up what product date labels mean. Where manufacturers now use any of 10 separate label phrases, ranging from “expires on” to “better if used by,” they’ll now be encouraged to use only two: “Use By” and “Best if Used By.”

The former is a safety designation, meant to indicate when perishable foods are no longer good. “Best if Used By” is a quality descriptor — a subjective guess of when the manufacturer thinks the product should be consumed for peak flavor.
