Professor Chris Elliott is something of a ‘food detective’.
A Professor of Food Safety and Microbiology at Queen's University Belfast and a founding director of its Institute for Global Food Security (IGFS), his work is all about developing scientific solutions to protect us from contaminated food, be it accidental or criminal.

Since then, his name’s become synonymous with solving cases of food fraud; today he receives regular tip-offs on everything from oregano scams to dodgy potatoes.
