Environmental organizations that sponsored the new law say banning the “sell by” stamp will keep more food out of the garbage bin, cutting down on methane produced at landfills.
The groups also hope the new law will cut down on confusion by requiring manufacturers to use the same phrases for date labels on all products.
California is the first state in the nation to pass the regulations, which were written by Assemblywoman Jacqui Irwin, a Thousand Oaks Democrat.
“Having to wonder whether our food is still good is an issue that we all have struggled with,” Irwin said in a statement. “Today’s signing of AB660 is a monumental step to keep money in the pockets of consumers while helping the environment and the planet.”
With the new law in California, dates may be voluntarily applied to meat, poultry, and egg products, provided that the dates are truthful and not misleading.
Irwin said some of the phrases currently used, such as “expires on,” “best before,” and “sell by,” can be unclear to average consumers. Some consumers may think the dates are equal to expiration dates, she explained in a legislative assessment of the bill.
The confusion leads to food being wasted, strained grocery budgets, and increasing emissions of methane—a type of greenhouse gas—from rotting food, according to Irwin.
Food packagers can continue to label products with a “sell by” date only if it is coded in a format that is not easily readable by consumers and does not use the phrase “sell by,” according to a legislative analysis.
The law also allows food to be donated after the “best if used by” date has passed.
Californians Against Waste, a nonprofit environmental advocacy organization, co-sponsored the bill with the Natural Resources Defense Council, a national coalition of 3 million environmental activists.
Inconsistent use of phrases like “sell by” and “expires on” can make it “impossible” for consumers who don’t want to throw away good food, according to Erica Parker, a policy associate with Californians Against Waste.
Victoria Rome, the California lobbyist for the Natural Resources Defense Council, said the bill’s signing will cut down on confusion.
The Natural Resources Defense Council said California’s food waste accounts for 41 percent of the state’s methane emissions.
The council also believes 80 percent of the fresh water Americans use is for food production, and 10 percent of energy in the country is used to produce and distribute food.
The new measure mandates the use of the terms across all products sold in California.
