The U.S. Food and Drug Administration (FDA) clears “slaughter-free” lab-grown chicken by California-based Upside Foods (image) as safe for consumption. The approval caps a decade of research to bring lab-grown meat substitutes to market, in hopes of reducing both factory farming’s carbon footprint and the cruelty of industrialized poultry production. “Now we shift focus towards what really matters in this industry, which is scale up,” says Good Food Institute scientist Liz Specht.
