What is lab-grown / cultivated meat?

Supported by 3 cited sources

Key Points

• 1Cultivated meat (also called cultured, cell-based, or lab-grown meat) is produced by taking a small sample of animal cells — typically via a painless biopsy — and growing them in a nutrient-rich medium inside a bioreactor. The result is genuine animal tissue, not a plant-based imitation. The process eliminates the need to raise and slaughter billions of animals annually.
• 2The potential benefits are substantial. A 2023 CE Delft life-cycle analysis projected that at scale with renewable energy, cultivated meat could reduce greenhouse gas emissions by 92%, land use by 95%, and water use by 78% compared to conventional beef. Even compared to chicken — the most efficient conventional meat — reductions would be significant. The animal welfare implications are transformative: producing meat without sentient suffering.
• 3Current limitations are real and should not be understated. As of early 2026, cultivated meat costs remain far above conventional meat despite dramatic decreases from the $330,000 hamburger of 2013. Scaling bioreactor capacity to meaningful production volumes is an unsolved engineering challenge. Energy use is a concern — some analyses suggest that if powered by fossil fuels, cultivated meat could have a larger carbon footprint than beef cattle (Lynch & Pierrehumbert, 2019). The growth medium has historically used fetal bovine serum (FBS), though most companies have developed or are developing animal-free alternatives.
• 4The vegan community is genuinely divided. Consequentialist vegans — those focused on reducing suffering — tend to support cultivated meat because it could eliminate the vast majority of animal suffering in food production. Abolitionist vegans often oppose it on the grounds that it perpetuates the commodification of animals and the cultural norm of eating animal tissue, even if no animal is directly harmed. Both positions have philosophical coherence.
• 5Regulatory status varies by country. Singapore approved Eat Just's cultivated chicken in 2020. The USDA and FDA jointly approved UPSIDE Foods and GOOD Meat for U.S. sale in 2023. The EU, UK, and many other jurisdictions are still developing regulatory frameworks. Israel and several other countries are actively investing in cultivated meat research.
