The National Farmers' Union has dubbed August 7th 'Self Sufficiency Day' - the date we'd run out of food if we didn't import any. But does it matter whether or not the UK is self-sufficient in food, and what impact does it have on food security? Felicity Evans chairs a lively discussion between Phil Bicknell, the NFU's chief economist, and Gene Philhower, agriculture councillor at the US Embassy in London.

New research has found that a bacterial pathogen that comes from cattle, sheep and other animals, and is suspected of being associated with Crohn's Disease in humans, is sometimes present in the fine spray from rivers and our bathroom showers. MAP, as it's known, has already been proven to cause Johne's Disease in cattle. Professor Roger Pickup from Lancaster University tells Felicity what his research revealed.

And, continuing a week of special reports to commemorate 100 years since the start of the First World War, we hear the remarkable story of Chrissie Squire from Dorset. She collected eggs for wounded soldiers and wrote poems and letters on the shells - an act of kindness that's remembered to this day.

Presented by Felicity Evans and produced in Bristol by Anna Jones.
