22 Sep 2016 –-- General Mill's troubled US yogurt business dented its latest quarterly sales, which fell seven percent year-on-year to $3.9bn, as the US packaged goods giant lost customers to rival organic yogurt providers. US yogurt sales represents General Mill's second largest category but sales of upstart brands such as Chobani are hurting sales of its flagship brand Yoplait. US yogurt sales fell 15 percent in the quarter, continuing a downward trend.
