As part of series of passionate encounters between scientists past and present, bacteriologist Hugh Pennington- an expert on E Coli outbreaks- looks back at his hero and fellow scientist Joseph Lister.

Lister has affected Hugh's life, and not just as he has been awarded the Lister Medal of the Society of Chemical Industry. As a pioneer of sterilisation, Lister banished bugs from the operating theatre. As an expert on E Coli outbreaks, Hugh Pennington has spent decades trying to discover where the bugs got back into food that should have been safe.

Hugh looks back upon the life of Joseph Lister and explores the connections between the great man and himself.
