For the first time, lab-grown meat has won approval for public consumption — but only in Singapore. San Francisco-based Eat Just has developed what it calls “cultured chicken.” The startup company describes its product as “real, high-quality meat created directly from animal cells for safe human consumption.” Singapore’s Food Agency has given the okay for the sale of this new type of chicken product. “This is a historic moment in the food system,” said Josh Tetrick, Eat Just’s chief executive.
