Inside a South Carolina factory, in industrial vats that stand five stories high, batches of algae are carefully tended, kept warm and fed corn syrup. There the algae, known as Schizochytrium, multiply quickly. The payoff, which comes after processing, is a substance that resembles corn oil. It tastes faintly fishy.
"How Millions of Cartons of 'Organic' Milk Contain an Oil Brewed in Industrial Vats of Algae" is from the June 05, 2017 Wonkblog section of The Washington Post. It was written by Peter Whoriskey and narrated by Sam Scholl.
