The government and farmers unions have agreed on the additional movement of animals on welfare grounds as the foot and mouth crisis continues to grip the UK. Restrictions on the movement of livestock during the foot and mouth crisis have been eased to allow pregnant animals currently left out in the open to be brought back to farms to give birth and for cattle to be milked. Carcasses of culled animals will also be shipped in sealed containers to rendering plants for burning rather than being left lying in fields.
