The whole of Great Britain has been put under an Avian Flu Prevention Zone, which means heightened biosecurity. Millions of birds, wild and farmed, are dead because of bird flu. For the first time, the disease has remained at high levels in the wild bird population throughout the summer. It has now re-entered domestic and farmed birds. DEFRA believes the disease is NOT being spread from farm to farm, or even from garden flocks to farms, but from wild birds to farmed poultry.

Anna Hill speaks to the Chief Veterinary Officer, Christine Middlemiss, and hears from a poultry producer who says he's been left mentally and physically stressed by the disease.

Also, as Farming Today's week long look at education continues, we visit Romilly Primary School in Barry where they've launched a new project, teaching the children about their agricultural neighbours.
