USDA approves first lab-grown meat in U.S, but Scientists, food safety experts aren’t sold on it
The U.S. Department of Agriculture on Wednesday approved the sale of lab-grown meat for the first time, giving two California-based food technology startups the green light to sell chicken grown in a lab from animal cells.This is disturbing, in that it is likely that the genes being manipulated can promote cancers.”The U.S. Department of Agriculture (USDA) on Wednesday approved the sale of lab-grown meat for the first time, giving two California-based food technology startups the green light to sell chicken grown in a lab from animal cells, The Associated Press (AP) reported.
The approval granted to Upside Foods and Good Meat — the first two companies to go through the regulatory approval process — makes the U.S. the second country in the world, behind Singapore, to allow sales of lab-grown or so-called “cultivated” meat.
The meat is made from cells from a living animal, a fertilized egg or a “special bank of stored cells” and cultivated in steel tanks. Over a series of weeks, it grows into sheets or masses, depending on the company, of muscle and connective tissue that are then formed into the shape of chicken cutlets and sausages, and cooked as food.
Despite the mainstream media boosterism around lab-grown meat’s alleged environmental benefits, many consumers are skeptical or even squeamish — either out of concerns for safety or simply because “it just sounds weird,” according to a recent poll by the AP-NORC Center for Public Affairs Research.
It is also extremely expensive to produce and cannot yet be produced at scale. Experts also question its safety.
“It is a dream come true,” said Uma Valeti, CEO of Upside Foods, in an interview with Reuters. “It marks a new era.”
“This announcement that we’re now able to produce and sell cultivated meat in the United States is a major moment for our company, the industry and the food system,” said Josh Tetrick, co-founder of Eat Just and CEO of its subsidiary, Good Meat, which makes the lab meat, in a statement on Wednesday morning.
The U.S. Food and Drug Administration (FDA) called the meat a “food revolution.”
The companies received USDA approval for federal inspections required to sell meat and poultry in the U.S., several months after the FDA said the meat was “safe for human consumption” last year and the USDA approved their commercial labels earlier this month.
Eric Schulze, Ph.D., Upside Food’s vice president of regulation and public policy, navigated the company through the regulatory process, ensuring the lab-grown meat was not subject to extra regulatory hurdles beyond that of any other regular meat product, “Because our chicken is meat!” Upside states on its website.
Prior to joining Upside, Schulze worked at the FDA, regulating the biotech industry. The companies plan to roll out the product publicly at exclusive restaurants — both are working with Michelin-starred chefs. Chef Dominique Crenn will serve up Upside’s lab chicken at San Francisco’s Bar Crenn, and Good Meat products will debut in one of several Washington, D.C., restaurants owned by celebrity chef José Andrés.
Other celebrity chefs are less enthusiastic about the meat. Chef Andrew Gruel tweeted:
Upside Foods also announced a “contest” to motivate consumers to enter for a chance to be among the first U.S. consumers to try the startup’s cell-cultivated chicken. And academic researchers are working to figure out out how to increase consumer acceptance of the meat, some with funding from the USDA.
How the ‘sausage’ gets made
Cell-cultivated meat is made using techniques developed in the biopharma industry. Cells from live animals or a cell bank — where “immortalized” cells are produced from cultured stem cells — are grown in large steel tanks called cultivators, or bioreactors.
The cells are “fed” a mixture of sugars, amino and fatty acids, salts, and vitamins to proliferate quickly. The patented processes used by the different companies vary. Upside Foods produces large sheets of muscle and connective tissue together that it then forms into shapes that look like chicken cutlets and sausages. Growing the meat takes about three weeks.
Good Meat grows the cells into large masses rather than sheets. “The produced chicken product resembles a conventional chicken product,” Good Meat wrote in its dossier to the FDA on the safety of its product.
Both companies have pilot plants for meat production in California. Upside Foods produces its meat in a 70,000-square-foot facility in Emeryville and Good Meat makes its meat at a 100,000-square-foot facility in Alameda.
Industry experts estimate the meat won’t be widely available for seven to 10 years. The AP reported that neither company would divulge the cost of a chicken cutlet. They only said the price had been reduced significantly since they began sampling the meat.
Eventually, they hope it will sell for about $20/pound, which they say is the average price for organic chicken.
Both companies anticipate expanding their operations into other kinds of meat.
‘Disturbing’ use of genetic engineering to promote continuous cell growth
The production methods used to create lab-grown meat raise a series of human health and food safety concerns, according to Jaydee Hanson and Julia Ranney at the Center for Food Safety (CFS).
They wrote that public patents from companies like Memphis Meats (rebranded as Upside Foods in 2021) and Eat Just (Good Meat) show the companies use growth factors that could promote the development of cancer-like or mutated cells in the lab meat that could be absorbed into the human bloodstream after digestion.
In an interview with The Defender, Hanson said:
“The company also notes that it is using genetic engineering to promote continuous growth of the cells. This is disturbing, in that it is likely that the genes being manipulated can promote cancers.”
