China's investigation into the alleged fixing of infant formula prices rumbled on this week as Beijing claimed companies at the centre of the investigation were knowingly breaking the law. More firms moved to lower prices, including Mead Johnson, Meiji and FrieslandCampina. Elsewhere, Kroger struck a deal to buy regional supermarket chain Harris Teeter, while just-food spoke with the CEO of Walkers Shortbread's US arm and the newly-appointed managing director of Futura Foods following the sale of a stake in the company to Danish dairy firm Nordex.
