Precision fermentation - producing animal proteins through microbial fermentation without animal involvement - is emerging as a welfare-aligned protein technology with potential to reduce farmed animal suffering at scale.
Precision fermentation represents one of the most promising long-term technologies for reducing farmed animal suffering, enabling animal-identical product formulations without the welfare costs of animal agriculture. Unlike cell-cultivated meat, precision fermentation proteins are already commercially available and regulatory-approved in multiple markets. As production scales and costs decrease, these proteins can displace animal-derived equivalents in products ranging from dairy to baking applications, reducing the animal welfare footprint of the food system.
