    Kristie Sullivan / 01 August 2020

    A free-range egg farm near Lethbridge has tested positive for bird flu.

    The affected property has been quarantined and the birds on the property are being destroyed.

    Movement controls are also in place prohibiting the movement of birds, equipment and products within and out of the restricted area until further notice.

      Second egg farm tests positive for bird flu
      Kristie Sullivan / 06 August 2020

      A second egg farm near Lethbridge has tested positive for avian influenza.

      Agriculture Victoria said the farm is within the existing Restricted Area and has been under movement restrictions and regular surveillance which has helped identify and contain the disease.

      An expanded Restricted Area that provides a buffer zone around the newly identified farm has been put in place, meaning the movement of poultry, birds, related equipment and products within and out of the designated Control Area of Golden Plains Shire is banned unless a permit has been granted by Agriculture Victoria until further notice...
