Lab-Grown Meat in 2026: From the First Cultivated Meatball to State Bans, Safety, and Climate Claims

In 2016, a startup called Memphis Meats unveiled the first meatball grown from animal cells rather than taken from a slaughtered animal. Headlines followed about when lab-grown meat would reach restaurants, and the company denied early reports that its products would be sold within months. It took seven more years. In 2023, the company, renamed Upside Foods, and another firm became the first in the United States to receive federal approval to sell cultivated chicken.

Since then, the story has taken unexpected turns. Production remains tiny and expensive, a growing number of states have banned cultivated meat entirely, and a federal appeals court upheld Florida’s ban in March 2026. This article explains how cultivated meat is made, how it is regulated, what is known about its safety and environmental impact, why states are banning it, and what consumers should know.

How Cultivated Meat Is Made

Cultivated meat, also called cultured, cell-based, or lab-grown meat, starts with a small sample of animal cells, often muscle stem cells or cells from a fertilized egg or cell bank. The cells are placed in a nutrient-rich growth medium containing amino acids, sugars, vitamins, minerals, and growth factors, inside bioreactors similar to those used in brewing or pharmaceutical manufacturing. The cells multiply and, in some processes, are encouraged to form muscle and fat tissue, sometimes on edible scaffolds. The harvested cell mass is then formed into products such as nuggets, cutlets, or sushi-grade fish. A 2012 review in Meat Science by Mark Post of Maastricht University, who later presented the first cultured beef burger in 2013, noted that producing meat that mimics conventional meat in appearance, smell, texture, and taste was a formidable challenge and that efficient production would depend on culture conditions, particularly the growth medium.

How It Is Regulated

In 2019, the FDA and USDA agreed to share oversight of cultivated meat and poultry. The FDA oversees cell collection, cell banks, and the growth and differentiation of cells, reviewing safety data in a pre-market consultation. Once cells are harvested, the USDA’s Food Safety and Inspection Service oversees processing and labeling for products from livestock and poultry, and requires facilities to operate under inspection. Cultivated seafood, except catfish, is regulated by the FDA alone. Under this framework, Upside Foods and GOOD Meat received approval for cultivated chicken in 2023, and additional companies, including a producer of cultivated salmon, have since completed FDA review. Products have so far been sold only in a handful of restaurants.

Is Cultivated Meat Safe to Eat?

Because cultivated meat is new, safety assessments focus on the production process. A 2021 review in Comprehensive Reviews in Food Science and Food Safety by Kimberly Ong and colleagues, developed through workshops with 87 industry representatives and researchers, identified potential hazards at each manufacturing step, including the stability and identity of cell lines, residues from growth media components such as growth factors and hormones, potential allergens, microbial contamination, and chemicals used in scaffolds or processing. The authors concluded that existing food safety approaches can largely be applied but highlighted research priorities, such as how cell lines change over many generations. Advocates note that sterile bioreactor production avoids contamination with intestinal bacteria like Salmonella and E. coli common in slaughter, while critics stress the lack of long-term consumption data. Regulators concluded the approved products were safe based on company data.

The Challenge of Scaling Up

Producing cultivated meat at prices and volumes comparable to conventional meat remains a major hurdle. A 2021 techno-economic analysis in Biotechnology and Bioengineering by chemical engineer David Humbird, commissioned by a philanthropic foundation, examined animal cell culture at industrial scale. He concluded that slow cell growth, metabolic inefficiency, the buildup of waste products, shear damage to cells, the high capital costs of sterile equipment, and expensive pharmaceutical-grade amino acids and growth factors would likely make cultivated meat costly unless major breakthroughs occur. Companies have since reported progress on cheaper, food-grade media and larger bioreactors, and at least one large-scale facility has been built, but cost and scale remain the industry’s central challenges.

The State Bans

As federal approvals arrived, a number of states moved in the opposite direction. According to Farm Progress, Florida became the first state to ban cell-cultured meat when its governor signed Senate Bill 1084 in May 2024, and Alabama quickly followed. Mississippi, Nebraska, Montana, and Indiana enacted bans or moratoriums in 2025, and Texas became the seventh state that September, with fines of up to $25,000 per day and potential felony charges for repeat violations. In March 2026, the 11th U.S. Circuit Court of Appeals ruled that federal poultry inspection law does not override Florida’s ban, because the ban does not regulate the company’s ingredients, facilities, or operations. A separate lawsuit by Upside Foods and cultivated salmon producer Wildtype, arguing that Texas’s ban unconstitutionally protects in-state producers from out-of-state competition, has been allowed to proceed. Other states have considered bans or labeling requirements.

Supporters of the bans cite protecting ranchers and farmers, honest labeling, and caution about products without long-term health records. Opponents, including some free-market advocates, argue that the bans are economic protectionism that denies consumers choice for products federal regulators have deemed safe. The debate cuts across usual political lines.

Is It Better for the Climate?

Environmental benefits are a central selling point, but the evidence is nuanced. A 2019 modeling study in Frontiers in Sustainable Food Systems by John Lynch and Raymond Pierrehumbert at Oxford compared the warming effects of cattle and cultured meat production over up to 1,000 years. Cattle emit methane, a potent but short-lived greenhouse gas, while cultured meat emissions are almost entirely carbon dioxide from energy use, which accumulates in the atmosphere. Under continuous high consumption, cultured meat caused less warming than cattle initially, but the gap narrowed over time, and in some scenarios cattle caused far less long-term warming. The authors concluded that cultured meat is not automatically climatically superior and that its benefits depend on decarbonizing energy production. Cultivated meat could still reduce land use, animal numbers, and some pollution compared with intensive livestock production.

Would People Eat It?

Consumer acceptance may be as important as technology. A 2018 study in Meat Science by Michael Siegrist and colleagues at ETH Zurich ran two experiments with Swiss participants and found low acceptance of cultured meat, largely because it was perceived as unnatural. Paradoxically, informing participants about how cultured meat is produced and its benefits increased acceptance of traditional meat. How the product was described mattered: nontechnical descriptions emphasizing the final product, rather than the laboratory process, improved acceptance. Surveys in the United States and elsewhere show mixed interest, with younger consumers generally more open, and many people remaining unfamiliar with the concept.

How It Compares With Plant-Based Meat

Cultivated meat is one of several alternatives to conventional meat. A 2020 review in Nature Communications by Natalie Rubio, Ning Xiang, and David Kaplan at Tufts University compared plant-based and cell-based approaches. Plant-based meats are already widely available and cheaper to produce but can struggle to match the taste and texture of animal meat, and some products are highly processed. Cell-based meat could more closely replicate animal tissue but faces greater technical, cost, and regulatory challenges. The authors noted that both approaches aim to reduce the public health, environmental, and animal welfare costs of intensive livestock production, and that hybrid products combining plant proteins with cultured cells may be a practical path forward.

Option	Availability	Key considerations
Conventional meat	Everywhere	Familiar; environmental and animal welfare impacts vary by system
Pasture-raised or organic meat	Widely available	Higher welfare standards; higher cost; land needs
Plant-based meat	Widely available	Lower emissions; often processed; sodium content varies
Cultivated meat	A few restaurants; banned in several states	Animal cells without slaughter; high cost; limited data
Whole-food plant proteins	Everywhere	Beans, lentils, tofu, nuts; inexpensive and well studied

Nutrition

Cultivated meat is designed to have a nutritional profile similar to conventional meat, providing protein and, depending on the product, fats. Because composition can be controlled, some developers have discussed adjusting fat profiles, for example increasing unsaturated fats. However, products sold so far are often blends with plant ingredients, and detailed nutritional comparisons are limited. Micronutrients such as iron and vitamin B12 that are naturally present in animal tissue may depend on the growth medium. As with any meat product, processing, added sodium, and cooking methods affect healthfulness.

Around the World

Singapore became the first country to approve cultivated meat for sale, approving cultivated chicken in 2020. Israel approved cultivated beef in 2024. Other countries, including the United Kingdom, have reviewed applications, and some have approved cultivated meat for pet food. Italy passed a law in 2023 banning the production and sale of cultivated meat, and several European agricultural ministers have voiced opposition, while the European Union has received its first applications for approval. The global regulatory picture remains mixed, reflecting differing priorities for innovation, agriculture, and food tradition.

Animal Welfare Questions

Cultivated meat promises meat without slaughter, a major motivation for many supporters. However, early production relied on fetal bovine serum, harvested from fetuses of slaughtered pregnant cows, as a growth medium ingredient. Most companies have since developed serum-free media, and approved products reportedly use serum-free processes. Cell lines may still originate from animal biopsies or eggs, though far fewer animals are needed than in conventional production. Whether cultivated meat fully resolves animal welfare concerns depends on these details, which advocates encourage companies to disclose.

Labeling Debates

How to label cultivated meat has been contentious. Livestock groups have pushed for terms that clearly distinguish it from conventional meat, while companies prefer terms that do not discourage purchase. The USDA has approved labels using the term “cell-cultivated,” and several states have passed laws requiring specific labeling of cultivated and plant-based meat products. Clear labeling allows consumers to make informed choices, a goal shared by both supporters and critics, though they differ on wording.

What It Means for Farmers and Ranchers

Many ranchers and farm groups view cultivated meat as a threat to rural livelihoods and traditions, which helps explain the state bans in agricultural states. Others argue that cultivated meat, if it ever scales, would likely complement rather than replace conventional meat for decades, given its current costs. Some analysts suggest that farmers could participate by supplying plant-based ingredients for growth media or by producing premium pasture-raised products for consumers who value traditional meat. The economic effects remain speculative because production volumes are still tiny.

Looking Ahead

The future of cultivated meat in the United States depends on technical progress in reducing costs, the outcome of court challenges to state bans, consumer acceptance, and investment, which has declined from its peak in the early 2020s. Hybrid products, cultivated seafood, and pet food may reach markets before cultivated meat becomes common in grocery stores. Meanwhile, debates over state bans raise broader questions about how new food technologies should be regulated and who decides what consumers can buy.

Why Early Predictions Were Too Optimistic

When the first cultivated meatball was unveiled in 2016, some advocates predicted cultivated meat would be in stores within a few years. Reports that products would be sold within months prompted denials from the company itself. The gap between laboratory demonstrations and commercial production proved far larger than expected: growing cells in small flasks is very different from producing tons of meat in sterile industrial bioreactors at competitive prices. Regulatory frameworks also had to be developed from scratch. The history of cultivated meat illustrates a common pattern in food technology, where early enthusiasm outpaces the practical realities of scaling and regulation.

Food Safety Compared With Conventional Meat

Conventional meat production carries well-known food safety risks. Contamination with bacteria such as Salmonella, Campylobacter, and E. coli often occurs during slaughter and processing, and antibiotic use in livestock contributes to antimicrobial resistance. Cultivated meat production in sterile bioreactors could, in principle, avoid intestinal contamination and reduce the need for antibiotics, though some processes use antibiotics in cell culture. On the other hand, cultivated meat introduces new considerations, such as residues of growth media components and the long-term stability of cell lines. Regulators evaluate these factors case by case.

Investment and the Industry’s Outlook

Investment in cultivated meat surged in the early 2020s, reaching billions of dollars globally, but declined sharply afterward as investors grew skeptical of timelines and costs. Several companies have scaled back, merged, or closed, while others continue to pursue approvals and partnerships, sometimes focusing on niche products such as cultivated seafood, premium items, or hybrid products that blend cultivated cells with plant proteins. Government funding in some countries, including Singapore, Israel, the Netherlands, and China, supports research. The industry’s trajectory over the next decade remains uncertain.

Questions Consumers Might Ask

What animal cells were used, and were any animals harmed in producing the cell line? Does the growth medium contain animal-derived ingredients? Is the product fully cultivated or blended with plant ingredients? Was it produced using renewable energy? How does its nutrition compare with conventional meat? Transparent answers to these questions can help consumers decide whether cultivated meat aligns with their values.

The Role of Cultivated Seafood

Cultivated seafood is advancing alongside cultivated meat. Because seafood other than catfish falls solely under FDA oversight, the regulatory path can be simpler. In 2025, a company producing cultivated salmon completed FDA review and began offering its product in a restaurant, before Texas’s ban took effect. Supporters argue cultivated seafood could relieve pressure on overfished species and avoid contaminants such as mercury and microplastics found in some wild fish, while critics note the same cost and scaling challenges. Seafood products like sushi-grade fish may be easier to produce than complex cuts of meat because they require less structured tissue.

Hybrid Products

Many cultivated meat products combine a modest share of cultivated animal cells with plant-based ingredients that provide bulk, texture, and lower cost. Hybrid products allow companies to bring items to market sooner while production capacity remains limited, and they can deliver some of the flavor of animal fat and protein. Labeling of hybrid products must indicate cultivated ingredients. Consumers should check ingredient lists to understand what portion of a product is cultivated.

Energy Use and Manufacturing Footprint

Because cultivated meat is produced in factories, its environmental footprint depends largely on energy for running bioreactors, maintaining sterile conditions, controlling temperature, and producing growth media ingredients. Life cycle assessments differ widely depending on assumptions about future technology and energy sources. Studies generally suggest that cultivated meat could use far less land and water than beef and produce less nutrient pollution, but its energy demand could be higher than that of poultry or pork production. Powering facilities with renewable energy is therefore central to any environmental claim. Consumers and policymakers evaluating such claims should ask what energy sources and production assumptions underlie them.

A Balanced View

Cultivated meat has moved from a 2016 meatball demonstration to federally approved products, but remains rare, expensive, and limited to a few restaurants. Safety assessments focus on cell lines, growth media, and contamination, and regulators have approved several products, though long-term consumption data are lacking. Climate benefits depend on clean energy, and scaling faces major technical barriers. Seven states have banned it, with courts so far upholding Florida’s ban. Supporters see potential benefits for animals and the environment; critics raise concerns about naturalness, economic impacts on ranchers, and unknowns. Consumers interested in reducing meat’s environmental footprint already have many accessible options, from plant proteins to higher-welfare meat.

Practical Takeaways

Know that cultivated meat is federally approved but sold only in a few restaurants and banned in several states. If you are curious, look for clear labeling such as “cell-cultivated.” For environmental and health goals today, consider eating more whole-food plant proteins and choosing higher-welfare meat. Follow developments in court cases and state laws if you are interested in access.

Common Myths

“Lab-grown meat is in grocery stores.” Approved products have been sold only in a handful of restaurants.

“Cultivated meat is plant-based.” It is made from real animal cells, unlike plant-based meat.

“It is always better for the climate.” Its climate impact depends on energy sources and may not beat cattle over the long term.

“Federal approval means it can be sold everywhere.” Several states ban it, and courts have upheld Florida’s ban.

“It is genetically modified.” Approved products have generally used non-genetically engineered cell lines, though some companies use engineered cells.

Key Terms

Cultivated meat: Meat grown from animal cells in bioreactors.

Bioreactor: A vessel in which cells are grown under controlled conditions.

Growth medium: The nutrient solution that feeds cells as they multiply.

Fetal bovine serum: A growth medium ingredient from cow fetuses, largely replaced by serum-free media.

Dormant Commerce Clause: A constitutional principle limiting state laws that discriminate against interstate commerce.

The Bottom Line

When Memphis Meats denied reports in its early years that lab-grown meat would soon be sold, it was right to be cautious: federal approval for cultivated chicken did not come until 2023, and the products remain limited to a few restaurants. Cultivated meat is grown from animal cells under FDA and USDA oversight, but faces major cost and scaling challenges, and its climate benefits depend on clean energy. Seven states have banned it, and a federal appeals court upheld Florida’s ban in March 2026, while a challenge to Texas’s ban continues. Whether cultivated meat becomes a meaningful part of the food supply will depend on technology, courts, and consumer acceptance.
