The United States should implement uniform federal labeling standards for alternative proteins.
Walk into any U.S. grocery store and you will find products marketed as “plant-based,” “meatless,” “fermentation-derived,” and “vegan protein” sitting side-by-side, with no uniform federal standard explaining what those terms mean.
Consumers frequently misinterpret plant-based products as nutritionally equivalent to conventional animal proteins or harbor misconceptions about their level of processing and perceived natural quality—misunderstandings that standardized labeling could address. The alternative protein sector is projected to reach $290 billion globally by 2035, yet the United States still lacks a single, mandatory federal labeling standard to govern it. That gap is not a minor inconvenience—it is a structural challenge that impacts consumers, burdens industry, and undermines U.S. competitiveness.
The regulatory problem is threefold. First, no legally binding definitions exist for product categories such as “cultivated meat” or “precision fermentation-derived protein,” allowing manufacturers to use terminology interchangeably and leaving consumers unable to make meaningfully informed choices. Second, federal oversight is split between the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA)—FDA regulates plant-based and fermentation products, while cell-cultivated meat and poultry fall under joint jurisdiction—creating inconsistent pre-market review and enforcement gaps. Finally, in the absence of federal leadership, states have passed their own conflicting rules: Missouri and Arkansas prohibit plant-based products from using any meat terminology, while Iowa permits such terms provided that the label includes a qualifier such as “plant-based” or “veggie,” forcing national companies to produce different packaging for different states.
The contrast with other nations is stark. Singapore mandates pre-market safety review and requires labels such as “cultivated” on all cell-based meat products—those grown from cultured cells rather than harvested from a living animal. The European Union’s Novel Foods Regulation requires pre-market authorization for cell-cultivated products and prohibits the unqualified use of dairy terms for plant-based alternatives. Israel and Brazil have both created formal novel food categories with dedicated labeling requirements. In January 2025, FDA issued draft guidance recommending source-specific naming for plant-based foods—a useful signal but one that falls short of a binding federal standard. The guidance recommends naming that is specific to the source of the food. This would demand complicated names such as “wheat, pea, and soy plant-based burger” or “cashew-based cheese alternative,” and compliance remains entirely voluntary.
The U.S. Congress and the executive branch should take coordinated action to impose new protein-labelling requirements. FDA and USDA should jointly establish legally enforceable definitions for plant-based, cell-cultivated, and precision fermentation-derived products and mandate disclosure of production method on the principal display panel. For cell-cultivated products, labels should state “grown directly from animal cells” in plain language, consistent with an approach such as Singapore’s. Labels using traditional “meat” or “dairy” terms for plant-based alternatives should consistently qualify them—for example, “plant-based burger”—while cell-cultivated and fermentation-derived products should use only their federally mandated descriptors. Labels should also include standardized nutritional information to facilitate easy comparison with conventional animal products. Robust allergen labeling requirements should be included, given that novel proteins and fermentation-derived ingredients may pose new allergenic risks not covered by existing federal standards.
To implement these changes, Congress should enact legislation to replace the state-level patchwork with a single national standard—eliminating compliance uncertainty and protecting interstate commerce. To prevent greenwashing—deceptive marketing that overstates a product’s environmental friendliness—and provide accurate information about the environmental impacts of protein production, the Federal Trade Commission, U.S. Environmental Protection Agency, and FDA should develop mandatory, science-based standards for environmental claims such as “sustainable” or “lower carbon footprint,” requiring third-party verification.
Implementation should begin with a dedicated interagency task force to draft a more effective rule, drawing on international examples. To support this effort, FDA should commission rigorous consumer research on terminology comprehension and labeling formats, including comparative analyses of consumer perception in leading international markets. The Good Food Institute, the Plant Based Foods Association, and conventional meat industry stakeholders all submitted public comments on FDA’s 2025 draft guidance, demonstrating that broad stakeholder engagement is already underway. Congress should allocate dedicated resources to FDA and USDA for effective monitoring and enforcement of the mandatory framework, including clear penalties for non-compliance. The framework should also mandate periodic review every three to five years to adapt to scientific advancements, evolving consumer understanding, and new international regulatory developments in this rapidly changing sector.
Alternative proteins are no longer a niche market. They are an emerging pillar of U.S. food policy, food security, and public health. Leaving their labeling to voluntary guidance and competing state laws is a regulatory choice—and an increasingly costly one. A mandatory, uniform federal framework will not only protect consumers and reduce legal uncertainty; it will position the United States to lead the global conversation on the future of food. The infrastructure for that framework, interagency coordination, public engagement, and FDA expertise already exists. What is missing is the political will to act.
