Ferrero reopens French Nutella plant
Ferrero has resumed operations at its biggest Nutella plant. The Italian confectioner halted production at its factory in the French town of Villers-Ecalles — which produces a third of all Nutella jars sold globally — on February 19 over a suspected quality issue. More than 365 million kilograms of Nutella are consumed each year. Last year, a 70% discount of the popular spread led to brawls in French supermarkets.
