Excerpt:
Liver fluke is the common name of the trematode, Fasciola hepatica. The parasite is found worldwide and is the only liver fluke found in Australia. Infection can lead to reduced productivity and death and costs millions of dollars each year in lost production (meat, wool, milk, liver condemnation, secondary infection, replacement stock requirements), stock deaths and costs of treatment and prevention. The fluke mainly affects cattle and sheep, but can also affect alpacas, goats, horses, pigs, kangaroos, wombats, rabbits and deer. Humans may also be infected, for example after eating watercress collected from fluke-infested creeks or following use of contaminated water on vegetable gardens. The adult fluke is a pale brown or grayish-brown flat worm about 1.5-4 cm long that lives in the bile ducts of the liver (Figure 1).
