The bottom line

Agribusiness giant Monsanto is looking to sell its dairy hormone business, which makes the artificial growth hormone Posilac, also called bovine somatotropin (BST). Posilac can increase a cow’s milk production by a gallon a day, but several countries ban it and consumer leeriness has prompted most U.S. milk sellers to avoid using it. Monsanto says BST is safe, and that Posilac is selling well. (The New York Times)
