2. Who Am I? Liver Fluke A fluke is a type of small, parasitic flatworm that feeds on the blood or body of its host. The sheep liver fluke attacks sheep and cattle and has even been known to infect humans, making them seriously ill. The Sheep liver fluke's eggs spread when they are eaten by pond snails. The eggs hatch into larvae which then eventually leave the snail. When a sheep eats a fluke, the fluke migrates to the sheep's liver where they grow into adult flukes. Humans can catch liver flukes by eating the improperly cooked meat of an infected animal. (Source: kidsbiology.com)
