Welfare Science

Precision Fermentation and Animal Welfare

Precision fermentation produces animal-identical proteins without animals, offering a transformative opportunity to reduce animal use in food production.

Key Facts

Precision fermentation uses microorganisms to produce proteins such as whey, casein, and egg white
Products are identical in function to animal-derived equivalents
Large-scale production could eliminate the need for some farmed animal industries
Regulatory approval pathways are advancing in the US, EU, and Singapore
Cost parity with conventional proteins is expected within the coming decade

Welfare Considerations

If precision fermentation scales successfully, it could eliminate suffering for billions of animals currently used in dairy and egg production, representing one of the largest welfare gains possible.
