THE Government's chief veterinary officer, Jim Scudamore, says vigilance must be maintained in the outbreak of swine fever. The ban on exports of live pigs is limited to Norfolk, Suffolk and Essex but Mr Scudamore said: "The disease can spread all too readily through movement of pigs, vehicles and people. We need everyone involved to continue to take a responsible attitude and help us with their active and vigilant co-operation.

"So far in the present outbreak we have been fortunate."
