The outbreak began in July on dairy farms owned by the Van Leeuwen Dairy Group near Waimate. There were now 13 infected properties, all thought to have had contact with van Leeuwen livestock. Cows on the infected van Leeuwen farms were being culled. ''We're still analysing what these latest positive properties mean for the wider response,'' Mr Gwyn said. Staff would take leave on the statutory holidays but were available on call, Mr Gwyn said.
