Anna Hill traces the food system from your burger back to the farm. Warwickshire farmers Richard Hall and Graham Hall sell their bulls for meat to ABP Food Group. They show Anna the systems in place to ensure traceability: from tagging calves' ears to having passports for each animal.

Anna follows the system along the the food chain through an abattoir in Norfolk and a sausage factory in Devon. Is it enough to guarantee authenticity on the label?

Presented by Anna Hill. Produced by Emma Weatherill.
