Strike hits production at world's biggest Nutella factory

Workers blockade French site, halting three production lines as ingredients run low

A factory in northern France that makes 25% of the world's Nutella has been blockaded for a week by workers demanding more pay, causing key ingredients to run low.

The Villers-icalles factory of the privately owned Italian confectionery company Ferrero normally produces 600,000 jars a day of the cocoa and hazelnut spread, making it the biggest Nutella producer in the world.
