Premier Foods, the UK group, this week surprised the market with a profit warning, sparking a slide in its shares and criticism in the City. Mondelez International announced its latest disposal, with Australian dairy Bega Cheese buying a clutch of brands including Vegemite. And possible IPOs grabbed the headlines, with UK own-label supplier Bakkavor rumoured to be mulling plans for a listing and Brazilian meat giant BRF confirming it is considering offering shares in halal arm OneFoods.
