Night Waves - Hugh Pennington

Hugh Pennington, Emeritus Professor of Bacteriology at Aberdeen University, is one of Britain's foremost experts on the science of food. Pennington's influence is felt everywhere from school kitchens to hospital wards. He led the government enquiries into outbreaks of E. coli in Scotland and Wales, and has been an advisor to the World Food Programme. Professor Pennington spells out the scientific and political fact behind the food fashions of our own time and looks ahead to the ethical, lifestyle and business challenges we must overcome if we are to feed the world. Matthew Sweets chairs the session recorded at this year's Free Thinking Festival. Producer: Victoria Shepherd.
