New California Law Aims to Clarify Food Expiry Dates and Reduce Waste
TL/DR –
A new labeling law has come into effect in California to provide clarity on food expiration dates, with the goal of enhancing consumer safety and reducing food waste. The law standardizes label language such as “Best if used by” versus “Use by”. The law has sparked discussions on similar legislation at the state and federal levels, considering that consumers in the United States dispose of around a third of the food they buy.
California Enforces New Food Labeling Law for Enhanced Safety and Clarity
This July witnessed the implementation of a new food labeling law in California aiming to clarify the dates when food is safe to eat and when it’s not, thereby reducing food wastage. Emily Broad Leib, the director of Harvard Law School’s Food Law and Policy Clinic, provides insight into the potential impact of this law and the need for similar legislation at state and federal levels.
The Role of Date Labels in Food Waste
Date labels on food products have been linked to food waste both at the household level and throughout the supply chain. This law aims to eliminate the confusion around the safety and quality of food past its labeled date. A national survey in 2025 showed that 43% of Americans throw food away due to the date on the label, not based on the condition of the food.
Understanding the Purpose of Date Labels
Contrary to popular belief, date labels on food aren’t primarily tied to food safety. Before these labels, people relied on their sensory judgment to determine if food was spoiling. Today, these labels are misunderstood to be safety indicators, leading to unnecessary food disposal. The date label is primarily used by food companies to indicate when their product is at its peak taste and freshness.
California’s Approach to Food Safety and Quality Labels
California’s new law requires companies to differentiate label language for foods concerning safety versus freshness. Standardizing these labels would help consumers understand that food past its date but in a good sensory condition is safe to eat. However, a small number of foods like certain deli meats and prepared salads require strict adherence to the “Use by” date due to the risk of listeria contamination.
The Influence of Consumer Handling and Storage Conditions
Consumer handling and storage conditions also affect food quality. For instance, if the refrigerator temperature is above the advised 40 degrees, food spoils faster. Fortunately, freezing food items can ignore the “Use by” date as freezing halts any processes leading to spoilage or illness.
The Impact of Misunderstanding Date Labels on Food Wastage
The misunderstanding of date labels significantly contributes to food wastage. A report by the EPA estimated that a household of four discards $3,000 worth of food each year. Research in the UK found that 20% of household food waste was due to date-label confusion.
Adoption of Similar Food Labeling Laws
California is the pioneer in implementing such a law, with New York following suit. Other states like Massachusetts have introduced similar bills. The ultimate goal is to adopt these laws at the federal level for uniformity and convenience, a move also supported by the Food Date Labeling Act.
