Sheila Dillon investigates the world of food and drink labelling; what has to go on, what doesn't, how we got here - and where things might be going.

A complex legislative framework has built up over many years in the UK - Sheila looks at the shape of today's labelling regulations, seeks to demystify some of the terms, and asks where things might mislead or confuse. On her journey Sheila goes down a rabbit hole, reveals some labelling surprises - and makes use of a time machine.

Her guide is Vitti Allender, who teaches food law at Cardiff Metropolitan University. The programme also features author and professor of religion Alan Levinovitz, Sue Davies who advises on food for the consumer rights organisation Which?, professor of food safety at Queen's University Belfast Chris Elliott who wrote a high-profile report on the UK's horsemeat scandal, Investigations Manager at the Advertising Standards Authority Jessica Tye, and wine importer and writer Doug Wregg.

The podcast and Monday broadcast of this edition also features Dan Charles, food and agriculture correspondent for NPR, on the controversy around the labelling of genetically modified organisms (GMOs) in the USA.

The podcast is an extended version of this programme.
