Precision fermentation produces animal proteins like dairy whey, egg white, and casein from microorganisms rather than animals. Its potential to reduce animal use at scale makes it a significant welfare technology.
Precision fermentation represents one of the most promising long-term solutions to farm animal welfare harms. By producing animal proteins without animals, it eliminates the welfare harm at the source while delivering products consumers want. Unlike plant-based substitutes that require consumers to accept taste and texture compromises, fermentation-derived proteins are chemically identical to animal originals. Accelerating the development and adoption of precision fermentation is a high-impact animal welfare intervention for those who can work in this space.
