Liver fluke disease in sheep and cattle

Up to 40 million sheep and 6 million cattle in Australia graze pastures where liver fluke is endemic. In 1999, it was estimated that graziers spent approximately $10 million a year on fluke drenches alone; with lost production costing a further $50–80 million a year. More recently, Lane and others (2015) estimated that the annual cost of fluke to the Australian sheep industry alone was about 25 million dollars.
