To amend the Federal Food, Drug, and Cosmetic Act to ensure consumer choice by requiring truthful labeling of lab-created butter, and for other purposes.

On June 22, 2026, Representative Tony Wied (R-WI-8) introduced HR9387, a bill to amend the Federal Food, Drug, and Cosmetic Act to require truthful labeling of lab-created butter. The bill has been referred to the House Committee on Energy and Commerce and has six cosponsors. It is in the earliest legislative stage with no committee hearings or markups scheduled. The bill authorizes no funding; it is a labeling mandate that would impose compliance costs on manufacturers of lab-created butter alternatives, including plant-based and precision-fermentation-derived products. The primary obligated parties are companies producing lab-created butter substitutes, such as those using fermentation technology (e.g., Perfect Day, which produces animal-free dairy proteins). However, these are private companies, not publicly traded. Among publicly traded food companies, exposure to lab-created butter is minimal. Campbell's (CPB), General Mills (GIS), Kellanova (K), and J.M. Smucker (SJM) are large packaged food companies that use dairy ingredients but do not have significant lab-created butter product lines. The labeling change would not materially affect their revenue or cost structures. The bill's legislative path is uncertain; it must pass through committee, the full House, the Senate, and be signed by The President. Given the early stage and lack of funding, the market impact is negligible. No real market data on stock price movements is available, but the structural impact on these companies is neutral.
