Precision fermentation produces animal proteins without farming animals. This emerging technology has significant potential to reduce animal suffering at scale.
Precision fermentation represents one of the most exciting technological opportunities to reduce animal suffering in the food system. By producing animal proteins through microbial fermentation rather than animal agriculture, it can deliver familiar food experiences without the welfare costs of farming sentient animals. Unlike cultivated meat, precision fermentation is already commercially scaled for some products. The welfare impact depends on consumer adoption and market penetration - every unit of animal protein replaced with a fermentation-produced equivalent represents an animal spared from farming.
