Available for over a year

A deadly strain of bird flu is sweeping across farms in the Midwest. We talk to farmers and trade bodies to find out what impact this crisis is having on the industry.

Today it's the turn of Chuka Umunna, business spokesperson from the Labour Party. Image: Chickens in cages Image credit: AP
