  1. Wart disease (Synchytrium endobioticum) is not known to have occurred on the land in which the potatoes were grown.
  2. Samples of soil from the land in which the potatoes were grown were drawn and tested by the Scottish Government prior to planting and revealed no trace of Potato cyst nematodes (Globodera rostochiensis and G. pallida).
    In addition the lots to be loaded were identified and samples of soil obtained from each lot making up the cargo were tested for Potato cyst nematodes. None of the samples of soil from the lots revealed the presence of viable cysts of Potato cyst nematodes.
