5 Biotech Products U.S. Regulators Arenít Ready For

New techniques being used to produce our food or shape the environment raise regulatory questions.

Lab-made meat. Hornless cattle. Designer bacteria. Dozens of futuristic-sounding products are being developed using new tools like CRISPR and synthetic biology. As companies seek to commercialize more of these products, one big question lingers: Who will regulate them?


A new report issued by the National Academy of Sciences says U.S. regulatory agencies need to prepare for new plants, animals, and microbes that will be hitting the market in the next five to 10 years. The new products, the report says, could overwhelm regulatory agencies like the U.S. Department of Agriculture and Food and Drug Administration.


ďAll of these products have the potential to be beneficial, but the question to me is, how do they compare to the alternative?Ē says Jennifer Kuzma, co-director of the Genetic Engineering and Society Center at North Carolina State University and a member of the National Academy of Sciences committee that prepared the report.


Here are some products scientists are already working on that U.S. regulatory agencies arenít ready for.


Living bacteria that act like drugs. Changes in the vast communities of microŲrganisms that live in and outside the human body may contribute to diseases, but scientists donít yet understand all these complex relationships. That isnít stopping companies trying to develop genetically engineered bacteria to treat a whole range of medical conditions, from cancer to metabolic disease. Ingested in pills, these living microŲrganisms could end up in wastewater and possibly drinking water. The U.S. Environmental Protection Agency might have to get involved.


Gene-edited animals and crops. Early this year, the FDA proposed new regulations requiring researchers to get approval for gene editing in cattle, pigs, dogs, and other animals. The FDA already regulates transgenic animalsóthose with DNA added from a different species, like genetically modified salmon. The proposed guidelines mean each alteration to an animalís own genome would be subject to approval.


Meanwhile, traditional genetically engineered crops are currently overseen by the USDA. Creating these crops usually involves inserting genes from other species. But so far, gene-edited foods havenít been subject to regulation because they donít contain foreign DNA. For example, Cellectis, an immunotherapy company that hosted the first gene-edited dinner, is tweaking existing genes so that plants will provide more nutritional value, stay fresh longer, and resist disease. Meanwhile, DuPont Pioneer is using CRISPR to make corn more resistant to drought.


Lab-grown meat. This week, startup Memphis Meats announced plans to start selling chicken grown from cultured animal cells beginning in 2021. The company is among a handful of startups aiming to develop animal-like proteins that donít require traditional agricultural methods. Lab-grown meat represents a more environmentally and ethically friendly way to produce food, but itís unclear how these products would be regulated. The U.S. Department of Agriculture controls real meat, dairy, and eggs, while the FDA monitors food additives and products made from human cells. Lab-made meat falls into a regulatory gray area, and thereís no precedent for approving these products.
