Food security, Ash dieback, Beef summit

What can be done to alleviate what beef farmers are calling a crisis over prices? Producers, processors and retailers will meet for a 'beef summit' later today.

Two farmers in Cornwall are fined, after identity ear tags were fraudulently removed from cows which had tested positive for TB.

And Anna Hill takes a walk in the woods with a specialist in ash dieback, who points out the mushrooms ready to release a deadly cargo of spores to infect yet more trees.

Presented by Anna Hill and produced by Emma Campbell.
