In 2001, Eric Schlosser published Fast Food Nation: an investigation into the toxic depths of America’s food industry.  Twenty five years later, the book remains an urgent intervention, as much for what it says about workers’ rights as for our agricultural systems and dietary health.

On Downstream this week, Ash Sarkar talks to Eric Schlosser about what’s changed since 2001, and what remains unreformed. How have we developed one food system for the rich and another for everyone else? Could the food industry operate – and America eat – without migrant workers? And did Eric foresee that marijuana edibles would become the new fast food?
