What’s really in your spice rack? In this exclusive investigation by The Food Programme, Jaega Wise investigates the authenticity of spices sold by a number of high street, online and health food chains. Using brand new technology outside of the lab for the first time, she will test herbs and spices from some of the biggest household names and retailers, including Tesco, Sainsbury’s, Asda, Amazon and more. Plus, we hear from leading experts on the UK’s food defence frontline to find out just how challenging it is to detect fraud and police this lucrative area.
