Africa's position as a market of growing importance for the world's dairy processors was underlined this week, with Danone and Arla Foods announcing moves to invest in the region. Conditions in the dairy sector, however, remain volatile, as shown by the 2015 results of Germany's largest dairy, DMK. Elsewhere, Campbell Soup Co. hailed the improvements it is making on its profitability but admitted parts of its US business are struggling to grow sales. Meanwhile, Australian baby food group Bellamy's posted strong first-half numbers and said its sales growth would quicken in the second half amid buoyant demand at home and in Asia.
