Liver fluke - a review

Summary

Liver fluke (Fasciola hepatica) is a parasite affecting a range of livestock and other species.

Final hosts in which it can develop to sexual maturity include livestock such as sheep, cattle, horses, pigs, goats, alpacas and deer. Other species include kangaroos, wallabies, rabbits, and humans.

People can be infected by eating water cress from creeks in fluke-infested country. Millions of sheep and cattle graze pastures where liver fluke is endemic, mainly in south-eastern Australia.

Liver fluke costs millions of dollars each year in lost production, stock deaths, and costs of treatment and prevention. As with many worms, most of the economic cost is associated with production losses from infections that may not be apparent.
