U.S. regulators on Monday cleared the way for the sale of beef from gene-edited cattle in coming years after the Food and Drug Administration concluded the animals do not raise any safety concerns.
The cattle by Recombinetics are the third genetically altered animals given the green light for human consumption in the U.S. after salmon and pigs. Many other foods already are made with genetically modified ingredients from crops like soybeans and corn.
The cattle reviewed by the FDA had genes altered with a technology called CRISPR to have short, slick coats that let them more easily withstand hot weather. Cattle that aren’t stressed by heat might pack on weight more easily, making for more efficient meat production.
The company did not say when home cooks or restaurants might be able to buy the beef, but the FDA said it could reach the market in as early as two years.
Unlike the salmon and pigs, the cattle did not have to go through a yearslong approval process. The FDA said the cattle were exempt from that because their genetic makeup is similar to other existing cattle and the trait can be found naturally in some breeds.
Dr. Steven Solomon, director of the FDA’s Center for Veterinary Medicine, said the agency’s review of Recombinetics’ cattle took several months. He said there’s no reason meat from the animals or their offspring would need to be labeled differently.
Solomon said a genetically altered animal marketed as having a special advantage — such a higher than normal ability to withstand heat — might need to go through the full approval process.
“This opens up a completely different pathway,” he said, noting the decision could be encouraging for other biotech companies, many of which are small startups.
