Precision fermentation uses microorganisms to produce animal proteins including dairy and egg proteins without animal involvement, offering major potential welfare benefits as the technology scales.
Precision fermentation represents a potentially transformative technology for animal welfare, offering the possibility of producing the functional proteins that make animal-derived foods distinctive without the farming systems that cause welfare harm. The technology is advancing rapidly and investor interest is significant. From an animal welfare standpoint, the priority is accelerating the cost-competitiveness and scale of these technologies while ensuring that growth media and production processes are genuinely animal-free. Consumer acceptance and regulatory pathways are the two non-technical barriers most requiring advocacy attention.
