Lab-Grown Meat in 2026: How Cultivated Meat Is Made, What Research Shows, and Why Seven States Banned It

Lab-grown meat, also called cultivated or cell-cultured meat, is real meat made by growing animal cells in steel tanks rather than raising and slaughtering animals. Supporters describe it as a way to reduce animal suffering, land use, and greenhouse gas emissions. Critics question its safety, cost, environmental footprint, and the influence of investors and tech companies on the food system. Several U.S. states have gone further and banned it outright.

A decade ago, cultivated meat existed mostly as a famously expensive laboratory burger. Since then, U.S. regulators have cleared cultivated chicken, salmon, and pork fat for sale, while seven states have prohibited or paused sales and a federal appeals court has upheld Florida’s ban. This article explains how cultivated meat is made, what regulators reviewed, what research shows about its environmental impact and consumer acceptance, and the open questions that matter for health-conscious consumers.

How Cultivated Meat Is Made

Producing cultivated meat starts with a small sample of cells from a living animal, such as muscle stem cells, fat precursor cells, or cells from a fertilized egg. The cells are placed in a nutrient-rich growth medium containing sugars, amino acids, vitamins, minerals, salts, and growth factors, the signaling proteins that tell cells to multiply and develop. They grow in bioreactors, large sterile vessels similar to those used to brew beer or make pharmaceuticals, where temperature, oxygen, and acidity are controlled. Once enough cells have grown, they may be encouraged to develop into muscle or fat and harvested. Many current products combine cultivated cells with plant proteins and binders to create textures similar to nuggets, ground meat, or fillets.

In a 2012 review in Meat Science, Mark Post of Maastricht University, whose team unveiled the first cultivated beef burger in 2013, explained that the technologies to grow skeletal muscle and fat tissue already existed but that producing meat efficiently would depend on growth media composition, maximizing protein synthesis, and mimicking the appearance, smell, texture, and taste of conventional meat. Those remain central challenges more than a decade later.

Early research relied on fetal bovine serum, a component harvested from the blood of calf fetuses at slaughter, to supply growth factors. Its cost, variability, and ethical problems for a product meant to reduce animal use pushed companies to develop serum-free media using recombinant proteins produced by microbes or plants. Reducing the cost of growth factors is one of the biggest hurdles to affordable cultivated meat.

How Cultivated Meat Is Regulated in the United States

Under a 2019 agreement, the FDA and the USDA’s Food Safety and Inspection Service share oversight of cultivated meat and poultry. The FDA oversees cell collection, cell banks, and the growing process, conducting a pre-market consultation in which companies submit data on their cell lines, media, production processes, and the safety of the final product. Once cells are harvested, the USDA takes over for products made from livestock and poultry, inspecting facilities and approving labels, as it does for conventional meat. Cultivated seafood, except catfish, is regulated by the FDA alone.

The FDA completed its first pre-market consultation for cultivated chicken from Upside Foods in November 2022, and in June 2023 the USDA granted inspection and label approval to Upside Foods and Good Meat, making cultivated chicken legal to sell in the United States. Sales began in a small number of restaurants. In 2025, the FDA completed a consultation on cultivated salmon from Wildtype, and the USDA cleared a cultivated pork fat ingredient from Mission Barns for use in products that combine it with plant protein. Other countries, including Singapore, which approved cultivated chicken in 2020, and Israel, have also authorized products, while Italy and some other jurisdictions have moved to restrict them.

Why Seven States Banned Lab-Grown Meat

Florida became the first state to ban cultivated meat in May 2024, followed by Alabama, then Mississippi, Nebraska, and Montana in 2025. Indiana enacted a two-year moratorium, and Texas passed a two-year ban that took effect in September 2025 with steep penalties. Supporters of the bans cited protection of ranchers and farmers, concerns about the safety of a new technology, and skepticism of investor-backed food companies. Critics, including some free-market and consumer groups, argued that the bans protect incumbent industries from competition and deny consumers choice for products federal regulators have already cleared.

Cultivated meat companies challenged the bans in court. In March 2026, a three-judge panel of the 11th Circuit Court of Appeals upheld Florida’s ban, ruling that because the law does not regulate Upside Foods’ ingredients, premises, facilities, or operations, federal poultry law does not preempt it. A separate challenge to the Texas ban was pending. The legal outcome means cultivated meat may remain unavailable in several states even as federal regulators clear new products.

Environmental Impact: Promise and Uncertainty

Environmental benefits are a central argument for cultivated meat. A 2011 life cycle assessment in Environmental Science and Technology by Hanna Tuomisto and Joost Teixeira de Mattos modeled large-scale production using cyanobacteria as the nutrient source and estimated that, compared with conventional European meat, cultivated meat could involve 7 to 45 percent lower energy use (except compared with poultry), 78 to 96 percent lower greenhouse gas emissions, 99 percent lower land use, and 82 to 96 percent lower water use. The authors noted high uncertainty, since no commercial facility existed.

Later work painted a more nuanced picture. A 2019 study in Frontiers in Sustainable Food Systems by John Lynch and Raymond Pierrehumbert at the University of Oxford modeled warming over centuries rather than using standard carbon dioxide equivalents. Cattle emit methane, a potent but short-lived greenhouse gas, while cultivated meat emissions are almost entirely carbon dioxide from energy use, which accumulates for centuries. Under continued high consumption, cultivated meat caused less warming than cattle at first, but the gap narrowed over time and in some scenarios cattle caused less long-term warming. The authors concluded that cultivated meat is not automatically better for the climate; its advantage depends on decarbonized energy and the production systems actually built.

Is Cultivated Meat Safe to Eat?

Regulators reviewed the safety of the products cleared so far, including cell line identity and stability, the absence of contamination, residues from growth media, and the composition of the final product. Because cultivated meat is grown in controlled, sterile conditions, proponents argue it could reduce risks associated with conventional meat, such as fecal contamination with pathogens like Salmonella and E. coli, and the use of antibiotics. Critics point out that long-term consumption data do not yet exist, that some processes use genetically modified or immortalized cell lines whose implications consumers may want to understand, and that growth media ingredients such as hormones and growth factors should be fully characterized. Food safety experts have identified issues to monitor, including potential allergens from media components, microbial contamination during production, and consistency across batches. Public data on approved products’ composition remain limited.

Nutrition: Is It the Same as Meat?

Cultivated meat is made of animal cells, so its basic protein and amino acid composition can resemble conventional meat. However, nutrient content depends on the cell types and the growth medium. Conventional meat contains iron, zinc, vitamin B12, and fats that come partly from the animal’s diet; in cultivated meat, these must be supplied through the medium or added. Producers can in principle adjust fat composition, for example increasing unsaturated fats, but current products are often blends of cultivated cells and plant ingredients, so their nutrition labels resemble processed meat analogues more than whole cuts. Independent nutritional analyses of commercial products are still scarce.

What Consumers Think

A 2018 systematic review in Meat Science by Christopher Bryant and Julie Barnett analyzed 14 empirical studies of consumer acceptance and found substantial demographic variation, with younger people, men, and people who already eat less meat or are concerned about animal welfare and the environment often more open to trying cultivated meat. Common objections included perceived unnaturalness, safety and health concerns, taste, price, and distrust of the companies and scientists involved. Perceived benefits included animal welfare, environmental sustainability, and food security. The authors noted that framing and terminology strongly influence attitudes, with terms like “lab-grown” often eliciting more negative reactions than “cultivated” or “clean” meat. Willingness to try is not the same as willingness to eat regularly, and acceptance will ultimately depend on taste and price.

Technical and Economic Hurdles

A 2018 review in Trends in Food Science and Technology by Neil Stephens and an interdisciplinary team identified key technical challenges, including finding reliable cell sources, developing affordable serum-free media, creating scaffolds that let cells form thick, structured tissues like steaks, and scaling bioreactors far beyond pharmaceutical volumes, along with socio-political and regulatory uncertainties. A 2020 review in Nature Communications by Natalie Rubio, Ning Xiang, and David Kaplan at Tufts University compared plant-based and cell-based approaches, describing the benefits and challenges of each for production efficiency, product characteristics, public health, the environment, and animal welfare. Both reviews emphasized that cultivated meat faces significant scale-up and cost barriers before it can compete with conventional meat.

Cost remains the biggest practical obstacle. Growth factors and sterile bioreactor capacity are expensive, and producing meat at the scale of the global market would require enormous facilities. Several cultivated meat companies have scaled back plans, delayed facilities, or shut down amid funding challenges, while others continue to pursue hybrid products that combine small amounts of cultivated cells with plant ingredients, which reduces cost while adding meat flavor. Industry observers expect cultivated meat to remain a niche product for years.

Labeling: What Will Packages Say?

How cultivated meat should be labeled has been debated by regulators, industry, and ranchers. The USDA approved labels using the term “cell-cultivated” for the first chicken products, and the agency has worked on rules for labeling meat and poultry made from cultured animal cells. Some states require terms such as “lab-grown” or “imitation” on packages, and Indiana’s law requires cultivated products to carry an imitation meat statement after its moratorium ends. Consumers should expect clear labeling distinguishing cultivated products from conventional meat, which helps those who want to seek out or avoid them.

Animal Welfare and Ethics

For many supporters, the strongest argument for cultivated meat is ethical: producing meat with far fewer animals and without slaughter. Cell lines can, in principle, be maintained indefinitely or refreshed with occasional biopsies from living animals. The shift away from fetal bovine serum addresses one ethical concern, though some products may still use animal-derived inputs. Religious authorities have debated whether cultivated meat can be kosher or halal, with some rabbinic and Islamic scholars indicating it could be permissible under certain conditions, depending on the source of cells and production methods. Ethical views also differ on whether high-tech solutions are the best response to concerns about animal agriculture compared with eating less meat or supporting higher-welfare farming.

Concerns About Corporate Control

Some critics worry that cultivated meat could concentrate food production in the hands of a few technology companies and investors holding patents on cell lines and processes, reducing the role of farmers and rural communities. Others argue that conventional meat is already highly concentrated, with a few meatpackers controlling most U.S. beef processing, and that new competitors could diversify the market. These debates echo broader discussions about technology, ownership, and fairness in the food system. Our article on agribusiness concentration explores related questions.

Alternatives for Eating Less Meat Today

For people interested in reducing meat for health, environmental, or ethical reasons, options exist today without waiting for cultivated meat. Beans, lentils, tofu, tempeh, nuts, and whole grains provide protein and fiber. Plant-based meat products offer familiar formats, though they are processed foods; our article on plant-based burgers reviews the evidence. Choosing smaller portions of meat, buying from farms with higher welfare and environmental standards, and eating more plant-forward meals are practical steps with established health benefits.

A Brief History of Cultivated Meat

The idea of growing meat without animals has circulated for nearly a century, but practical research began in the early 2000s, including NASA-funded experiments on growing fish tissue for astronauts. In 2013, Mark Post’s team in the Netherlands presented the first cultivated beef burger at a London tasting, a demonstration that reportedly cost more than $300,000 to produce. The following decade saw a wave of startups and billions of dollars in investment, with companies working on chicken, beef, pork, seafood, and pet food. Singapore became the first country to approve sales of cultivated chicken in 2020, followed by the United States in 2023. Investment slowed after 2022 as costs and scale-up challenges became clearer, and the industry entered a period of consolidation.

Cultivated Seafood

Seafood is a particular focus for some companies because wild fisheries face overfishing and farmed fish raise environmental and welfare concerns. Cultivated salmon, tuna, and shellfish could in principle avoid mercury and microplastic contamination found in some wild fish, although this depends on production methods and has not been fully studied. Because the FDA alone regulates most seafood, the regulatory path for cultivated fish is somewhat simpler than for cultivated poultry or beef. The FDA’s 2025 consultation on cultivated salmon made it the first cultivated seafood cleared in the United States.

Hybrid Products

Because producing pure cultivated tissue at scale is costly, many companies are developing hybrid products in which a small percentage of cultivated cells, such as fat cells, is blended with plant proteins. The cultivated component adds authentic meat flavor and texture, while plant ingredients reduce cost. The cultivated pork fat cleared in 2025, for example, is used in meatballs and bacon-style products made primarily from plant protein. Hybrid products may be the most realistic near-term path to market, though they blur the line between cultivated and plant-based meat for consumers.

The International Landscape

Countries have taken different approaches. Singapore has approved several cultivated products and invested in alternative protein research as part of its food security strategy. Israel approved cultivated beef in 2024. The European Union treats cultivated meat as a novel food requiring safety assessment, while Italy passed a national ban in 2023 that the European Commission questioned. The United Kingdom has approved cultivated meat for pet food and is reviewing applications for human food. China has included cultivated meat in agricultural research plans. These differences mean that the industry’s future will depend on policy choices around the world as much as technology.

Health Questions Worth Watching

Several health-related questions deserve attention as products reach more consumers. Will cultivated meat be processed with additives similar to other meat analogues, and what will sodium and fat levels look like? Could the absence of antibiotics in production help reduce antimicrobial resistance associated with livestock farming? Will the ability to adjust fat composition lead to healthier products, or will companies prioritize taste and cost? Does cultivated red meat carry the same associations with colorectal cancer seen with conventional red and processed meat, which partly relate to heme iron and processing? These questions will require independent research once products are widely available.

Practical Takeaways

Cultivated meat is unlikely to be a significant part of most diets in the near future. If you encounter it, read the label to understand how much is cultivated versus plant-based and check nutrition facts as you would for any processed product. If you want to reduce conventional meat for health or environmental reasons, plant proteins and smaller portions of responsibly raised meat are effective options available today. Follow regulatory decisions and independent research rather than marketing claims from either the cultivated meat industry or its opponents, and revisit your view as better evidence becomes available.

The Economics of Scaling Up

Pharmaceutical bioreactors produce small volumes of high-value products such as vaccines and antibodies, where cost per kilogram matters little. Meat is a low-cost commodity produced in enormous quantities, so cultivated meat must achieve efficiencies far beyond those of pharmaceutical manufacturing. Analysts have debated whether costs can fall to competitive levels, citing the expense of growth factors, sterility requirements, energy, and capital costs for large facilities. Some companies have opened pilot plants, while others have paused construction. The pace of cost reductions will determine whether cultivated meat moves from novelty to everyday food.

Farmers and Ranchers’ Perspective

Ranchers and livestock organizations have been among the strongest supporters of state bans, arguing that cultivated meat could mislead consumers, threaten rural livelihoods, and undermine traditional agriculture. Some farm groups have focused instead on labeling, insisting that only products from slaughtered animals be called meat. Others see opportunities, such as supplying cells or partnering with cultivated companies. The debate reflects deeper questions about the future of rural economies and who benefits from changes in how protein is produced. Finding ways for farmers to share in new technologies, rather than being displaced by them, will shape how rural communities view cultivated meat in the years ahead.

Common Myths

“Lab-grown meat is fake meat.” It is made of real animal cells, though often blended with plant ingredients.

“Cultivated meat is widely sold.” Availability is very limited, mostly in a few restaurants, and it is banned in seven states.

“It is definitely better for the climate.” Benefits depend on clean energy and production methods.

“Regulators never reviewed its safety.” The FDA and USDA reviewed approved products, though long-term data are limited.

“It contains no animal inputs at all.” It requires animal cells, and some processes may still use animal-derived ingredients.

Key Terms

Cultivated meat: Meat produced by growing animal cells outside an animal.

Bioreactor: A controlled vessel used to grow cells.

Growth medium: The nutrient solution that feeds cells.

Growth factors: Signaling proteins that stimulate cell growth and development.

Pre-market consultation: The FDA’s review of a new food’s production and safety before sale.

What Researchers Still Need to Learn

Many questions remain open. Researchers and regulators want independent analyses of the composition and nutrition of commercial cultivated products, long-term monitoring of consumers, life cycle assessments based on real facilities rather than models, and transparency about growth media ingredients and cell line characteristics. Economists want to understand whether production costs can fall enough to compete with conventional meat. Social scientists study how labeling, trust, and cultural values shape acceptance. Answers to these questions will determine whether cultivated meat becomes a meaningful part of the food system or remains a specialty product.

Questions to Ask Before Trying Cultivated Meat

Consumers who encounter cultivated products can ask: What animal cells were used, and were they genetically modified or immortalized? What is in the growth medium? How much of the product is cultivated cells versus plant ingredients? What are the nutrition facts, including sodium and fat? What allergens does it contain? How was the product reviewed by regulators? Companies with nothing to hide should be willing to answer, and clear answers help consumers decide whether the product fits their values and health goals.

A Balanced View

Cultivated meat is a genuine technological achievement that regulators have cleared for sale, with potential benefits for animal welfare, antibiotic use, and land use. Its climate advantage is real only if powered by clean energy, and its costs, scale-up challenges, and limited long-term data are significant. State bans reflect a mix of legitimate caution, cultural values, and protection of established industries. Consumers can follow developments with an open but critical mind, judging products by transparent evidence on safety, nutrition, environmental impact, and price.

The Bottom Line

Lab-grown meat is real meat grown from animal cells, cleared by U.S. regulators for chicken in 2023 and for salmon and pork fat in 2025, but still expensive, scarce, and banned in seven states, with a federal appeals court upholding Florida’s ban in 2026. Early models projected large environmental gains, but later climate research showed benefits depend on decarbonized energy. Consumer acceptance varies, and key questions about scale, cost, growth media, nutrition, and long-term effects remain. For now, people seeking to eat less conventional meat have proven options in whole plant proteins and smaller portions of responsibly raised meat, while cultivated meat develops.
