Campylobacter trials

We go to a farm that's trialing ways of reducing the incidence of campylobacter in live chickens. This bacterium is the biggest cause of food poisoning in the UK. Several farms are stopping the process of 'thinning' - where half the birds are taken out of the sheds to sell, while the rest are left to fatten. Thinning is thought to increase the spread of infection.
And we hear from a researcher speaking at a conference on rural affairs, who says governments should get involved in increasing the amount of food we grow in urban areas.
