Millions of hectares have been burnt in the Australian bushfires. While farmers count the cost, we hear whether there will be an impact on agricultural trade across the world. We visit a pig farm in Wiltshire where the piglets are born outdoors but once they're weaned, brought inside to fatten up. Pork labelling can be confusing. You may have seen 'outdoor bred' or 'outdoor reared' and some 'free range', and each of these labels means different things. Phil Brooke is Research and Education Manager at Compassion in World Farming, which has been campaigning for clearer food labelling. He explains what the different pork labels mean.
