• Infected dogs pass many thousands of (T.ovis) eggs in their faeces onto the pasture
  • Sheep and goats eat these eggs (which may survive for some months)
  • Eggs can also become distributed over large areas by wind and by flies.
  • On farm dogs post the biggest risk, but infection also results from visiting farm dogs, neighbours dogs and visiting town dogs.
  • Check here for treatment of dogs and for limiting on-farm contamination from visiting dogs.
