Our shops are full of products sourced from all over the world, and its someone’s job to find and secure them – at the right quality and quantity for the best price possible. In this programme Ruth Alexander speaks to three food buyers on three different continents. She is joined by Beatrice Muraguri, a Tea Buyer and exporter based in Mombasa, Kenya; Chloe Doutre-Roussel, who travels the world sourcing cacao beans for speciality chocolate makers. And Jim Gulkin, the chief executive of a trading company, which deals mainly in frozen seafood based in Bangkok, Thailand.
