Food poisoning meets economics in this episode of the Food Chain. And it's a toxic mix.

We'll explore how an outbreak can bring down a company, badly damage an industry and shine a light on social and economic inequalities and our globalising food system. Emily Thomas talks to a top food poisoning lawyer in the US, who has won more than $600 million for clients in foodborne-illness cases. And a former banker explains why a dodgy sandwich inspired him to quit his day job for the cause. Plus, how do you prove where you got food poisoning from and what can you do to avoid it?
