A new law in California will clarify ‘sell by’ dates to reduce food waste

A New Regulation in California Aims to Address Food Waste Through Standardized Labeling

A new law in California will - In a recent development, California has introduced a groundbreaking law designed to streamline food labeling and curb unnecessary waste. The legislation, which takes effect in early 2027, seeks to resolve the ambiguity surrounding "sell by" dates by creating a unified system for their interpretation. This initiative, spearheaded by the Californians Against Waste organization, marks a significant step in the state's effort to combat food insecurity and environmental impact.

Understanding the Problem: Misinterpretation of Dates

Food waste in California has long been a pressing issue, with millions of pounds of edible food discarded annually due to consumer misconceptions. "Sell by" dates, often misread as indicators of food safety, lead many shoppers to throw away items well before they expire. According to data from the U.S. Department of Agriculture, nearly half of all food waste in the U.S. stems from date confusion, with California contributing significantly to this trend.

"Consumers see 'sell by' dates and assume the food is no longer safe to eat, even when it’s perfectly good," explains Nick Lapis, a spokesperson for Californians Against Waste. "This creates a cycle where perfectly usable food is wasted, and retailers face unnecessary losses."

The law’s primary goal is to eliminate this misunderstanding by clearly distinguishing between "use by" and "best by" dates. While "use by" dates indicate when food should be consumed for optimal quality, "best by" dates are more about freshness and taste. By standardizing these labels, the legislation aims to empower consumers with accurate information, reducing the likelihood of premature disposal.

The Legislative Framework: A Collaborative Effort

California’s new law is the result of years of advocacy by environmental and consumer groups. Nick Lapis, who has been working with the organization for over a decade, highlights the importance of aligning with industry standards. "This law was crafted through collaboration with food retailers, packaging companies, and public health experts to ensure it is practical and effective," he notes.

The regulation mandates that all food labels include explicit definitions for date terms. For instance, "use by" will be labeled as "Best by" to emphasize that it refers to quality rather than safety. Additionally, the law requires retailers to adopt consistent labeling practices, ensuring that dates are clearly visible and standardized across all products. This approach not only aids consumers but also simplifies operations for businesses, reducing the risk of disputes over expiration.

Lapis emphasizes that the law is part of a broader strategy to make food waste a top priority. "California has some of the highest food waste rates in the nation, and this legislation is a critical tool in the fight against it," he says. "By changing how we perceive these dates, we can redirect food from landfills to plates."

Expected Outcomes: A Ripple Effect on Sustainability

Experts estimate that the law could prevent up to 15% of food waste in the state within the first year of implementation. This projection is based on studies showing that standardized dates reduce consumer hesitation to purchase items nearing expiration. For example, a 2024 report by the California Food Policy Council found that households with clear labeling guidelines were 30% more likely to consume food past its "best by" date.

The law also has economic implications. By extending the shelf life of products, retailers may save an estimated $200 million annually in food disposal costs. Moreover, consumers could benefit from lower grocery bills as they buy more food before it goes bad. "This is a win-win for everyone," says Lapis. "Retailers reduce losses, and families save money while eating more sustainably."

Environmental advocates are equally optimistic. Food waste contributes to greenhouse gas emissions through methane released during decomposition in landfills. Reducing this waste by even a small margin could have a measurable impact on California’s carbon footprint. "Every pound of food saved is a step toward a greener future," Lapis adds.

Challenges and Future Prospects

While the law is seen as a positive step, challenges remain in its implementation. Some retailers have expressed concerns about the cost of updating packaging and training staff. However, the state has allocated $10 million in grants to assist small businesses in transitioning to the new standards. "We’re working closely with retailers to ensure they have the resources needed," Lapis says.

Another hurdle is consumer awareness. Even with clear labels, many people may need time to adjust their habits. To address this, the California Department of Resources has launched a public education campaign. The initiative includes social media outreach, in-store signage, and partnerships with local grocery chains to host workshops on date interpretation.

"It’s not just about changing labels—it’s about changing behavior," Lapis states. "We need to teach people that 'best by' doesn’t mean 'unsafe by' and that many foods are still edible long after their date expires."

The law also sets a precedent for other states. If successful, California’s approach could inspire similar legislation nationwide. "We’re not just solving a local issue; we’re creating a model for the country," Lapis explains. "By clearly defining date terms, we can reduce waste on a larger scale."

Broader Implications for Food Systems

California’s legislation is part of a growing movement to rethink how food is labeled and distributed. In recent years, cities like San Francisco and Los Angeles have implemented similar measures, but this state-wide law amplifies their impact. The policy aligns with the United Nations’ Sustainable Development Goals, particularly those focused on responsible consumption and production.

Lapis points to the role of food banks in the equation. "Many food items labeled as expired are still safe to eat and could be redistributed to those in need." The law’s provisions are expected to increase the amount of usable food available to food banks, further addressing hunger in the state. "We’re talking about millions of meals that could be saved," he says.

Looking ahead, the organization plans to measure the law’s effectiveness through quarterly reports. Metrics such as food recovery rates, consumer behavior changes, and economic savings will be key indicators of success. Lapis also highlights the importance of continued public engagement. "Even after the law is in place, we need to keep educating consumers to make lasting change."

A Call for National Adoption

While California’s law is a milestone, Lapis stresses the need for federal action. "We’ve made progress, but without national standards, the impact will be limited." He cites the Food Date Labeling Act, a proposed federal bill that aims to create a unified labeling system across the U.S. "California’s law is a proof of concept for what’s possible on a national level."

The state’s initiative has already sparked interest from other regions. For example, Oregon is currently drafting similar legislation, and New York City is considering implementing it in its public schools. "We’re seeing a shift in how food waste is perceived as a problem that can be solved," Lapis remarks.

As the law rolls out, its success will depend on collaboration between stakeholders. "This isn’t a one-size-fits-all solution, but it’s a critical component of a larger strategy," Lapis says. "By making dates more transparent, we’re giving people the tools they need to make informed choices."

With the potential to save millions of pounds of food and reduce environmental harm, California’s new regulation represents a transformative approach to sustainability. It underscores the power of policy in shaping consumer habits and highlights the importance of clarity in everyday choices. As Lapis concludes, "The goal is to create a culture where food is valued for what it is—nutrition, not a ticking clock." This shift in mindset, supported by clear labeling, could redefine how food is managed in California and beyond.
