Cultivated Meat and Animal Welfare: Promise, Cell Lines, and Ethical Complexities

Cultivated meat — produced by growing animal cells in bioreactors — could dramatically reduce farmed animal suffering. But its animal welfare implications are more nuanced than headline claims suggest.

Key Facts

Cultivated meat is produced by taking cells from living animals and culturing them in nutrient media to produce muscle tissue without slaughtering the animal.
Cell line establishment typically requires biopsy from living animals — a procedure that can be performed with appropriate anaesthesia and minimal welfare harm.
Foetal bovine serum (FBS), derived from foetal calf blood, has been the standard growth medium for cell culture; it involves a significant welfare cost in its production from pregnant cattle.
The cultivated meat industry is actively developing FBS-free media using plant-based or precision fermentation-derived growth factors — eliminating this welfare cost when successfully scaled.
If cultivated meat achieves cost parity with conventional meat and is adopted at scale, it could reduce farmed animal numbers by billions — a transformative welfare outcome.
Regulatory approval has been granted in Singapore and the US; scaling from laboratory to commercial production remains the primary technical challenge.

Welfare Considerations

Cultivated meat's welfare promise is real but not unconditional. The pathway to dramatically reduced farmed animal suffering exists, but depends on: successful elimination of FBS from growth media (removing ongoing welfare costs of cell line maintenance), scaling to price parity with conventional meat, and consumer adoption sufficient to displace conventional production. Each of these represents a significant uncertainty. The animal welfare movement's relationship with cultivated meat should be enthusiastic but critically engaged — supporting research and development while advocating for FBS-free production and transparent welfare accounting as prerequisites for cultivated meat to fulfil its promise.

What You Can Do

Support the Good Food Institute's open-access research into cultivated meat technology, including FBS-free media development.
Advocate for government research funding for alternative protein technologies including cultivated meat.
Engage with policy debates about cultivated meat regulation, ensuring welfare criteria (FBS-free production) are part of approval frameworks.
Support alternative protein companies that demonstrate genuine welfare improvements over conventional animal agriculture.
Share accurate information about cultivated meat's welfare implications — both the promise and the remaining challenges.
