In this programme, Ruth Alexander hears why high food prices and the war in Ukraine mean food fraud is more likely to happen. She visits a laboratory in Belfast in Northern Ireland, where food products are analysed to sort what’s real and what’s fake, and she speaks to a food fraud investigator who tells us just how difficult it is to stop the criminals.

And we hear from a spice market in Delhi where vendors and shoppers tell us how they try to avoid fake products.
