European retail giant Delhaize this week named its new CEO - ex-Metro executive Frans Muller - but his appointment, combined with the departure of its US boss, hit the company's shares. In the US, Mondelez International gave more detail on its plans to shake up its plant network and use fewer suppliers. And an investor in Smithfield Foods insisted it had received interest from rival suitors for the US pork giant that could be better value than the current agreed takeover bid from China's Shuanghui International.
