It took two decades for the first genetically engineered animal to get approved for your dinner. Now that AquAdvantage salmon—with DNA engineered from three species—is moving forward, more genetically modified meat is likely to follow. But it’s not clear how long that will take.
Outside the United States, bacon might be next. Researchers at Seoul National University tweaked a gene in pigs that makes them super-muscly, yielding more pork per giant pig butt. Now, the scientists hope to sell their modified pig sperm to farmers in China, where engineered food can sometimes move to market more quickly.
