Understand Policy Issues
The date labels on food packaging accompanied by phrases such as “use by,” “best before,” “sell by,” “enjoy by” and “expires on” are generally intended to communicate food quality, not food safety. Nevertheless, date labels exert a powerful influence on consumers and food vendors. Under federal law, date labels are almost entirely unregulated. States have filled the void with a wide variety of regulations that often fail to reflect the distinction between food safety and food quality. The extreme variations demonstrate how our current system creates confusion for consumers while not necessarily improving food safety, ultimately resulting in significant waste of wholesome food.
Below is a sampling of state regulations, illustrating the arbitrary variability that currently exists across the United States:
- Connecticut requires date labels on dairy products, and does not restrict the sale of these products after the labeled date.
- Michigan requires date labels on pre-packaged perishable foods and dairy products, and restricts the sale of both of these items—as well as meat—once the labeled date has passed.
- Montana requires that milk be labeled with a “sell by” date of 12 days from the date of pasteurization, and bans the sale or donation of milk after that date.
ReFED found that standardizing date labels nationally was the most cost-effective solution to this country’s food waste problem. The fairly simple solution has the potential to divert 425,000 tons of food waste per year and provide $1.83 billion in annual economic value.

Proposed Solutions
Food Date Labeling Act
No national uniform system for food date labeling exists in the U.S. In the absence of federal law, states enforce a variety of inconsistent date label regulations. The Food Date Labeling Act of 2025 was proposed as a bi-partisan bill in July 2025, with the intent of establishing a uniform national system for date labeling that clearly distinguishes between foods that bear a label indicating quality from foods that bear a label indicating they may become unsafe to consume past the date. This bill would also ensure that food is allowed to be sold or donated after its quality date and proposes to educate consumers about the meaning of new labels so that they can make better economic and safety decisions.
USDA AND FDA GUIDANCE ON DATE LABELING
On December 14, 2016, the U.S. Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS) updated its guidance on food product labeling, which now encourages food manufacturers and retailers to use a “Best if Used By” date on their products. In May 2019, FDA released a letter similarly encouraging the food industry to use the phrase "Best if Used By" on food products to indicate quality. According to a national survey, “best if used by” is the phrase most easily understood by consumers as an indicator of quality. Despite these steps at providing guidance, neither USDA nor FDA require food companies to use this standard term for quality-based labeling, nor do they require standard language for labels intended to communicate safety. Since federal regulations do not require date labeling or set standardized language (except in the case of infant formula), it is up to the manufacturer’s discretion to determine which phrases to use. However, even without federal legislation, these agencies have the authority to adopt requirements that food companies use clear, consistent language that makes sense to consumers and are standardized across products.

COMMENTS ON THE U.S. GOVERNMENT'S REQUEST FOR INFORMATION ON FOOD DATE LABELING
The Zero Food Waste Coalition (ZFWC) submitted this comment in response to the U.S. Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS), and the U.S. Food and Drug Administration (FDA) Request for Information on Food Date Labeling. ZFWC was launched by Natural Resources Defense Council (NRDC), World Wildlife Fund (WWF), ReFED, and The Harvard Law School Food Law and Policy Clinic (FLPC) and has over 250 members across all 50 states. Since its inception, the ZFWC has supported federal standardization of food date labels, including through its support of the bipartisan Food Date Labeling Act and its engagement around the National Strategy for Reducing Food Loss and Waste and Recycling Organics. In these comments, the ZFWC urges the USDA FSIS and FDA to standardize food date labels across the United States. The comments highlight how inconsistent state regulations drive consumer confusion, create logistical complexities for businesses, and increase food costs for families. ZFWC recommends limiting date labels to “BEST If Used By” (quality) and “USE By” (safety), along with national consumer education efforts to promote understanding of standardized labels.

Date Labels: The Case for Federal Legislation
This report, published by the Harvard Law School Food Law and Policy Clinic, provides an updated analysis of the challenges with voluntary approaches to date labeling standardization and explains why federal legislation is needed to standardize date labels, permit the sale and donation of past date items, and provide meaningful consumer education on date labels that would significantly reduce food waste

EXPIRED, created by the Harvard Food Law and Policy Clinic, provides comprehensive information on date labeling and an overview of policy solutions. EXPIRED includes a regularly updated list of pending legislation and alerts for advocacy opportunities. The site also contains a short film, which discusses how state date labeling laws and consumer confusion contribute to the problem of food waste.
Promoting Food Donation: Date Labeling Law and Policy
After reviewing global date labeling and food donation policies, the Harvard Law School Food Law and Policy Clinic published this policy issue brief in November 2021. The issue brief analyzes global policies and best practices, and sets forth recommendations to standardize date labeling, allow the sale and donation of safe past date foods, and provide education to maximize the effectiveness of these standardized labels.
