Zoonotic worms—blame the dog, not the sheep

Few worms can transfer from animals to humans, but none come directly from sheep. The Hydatid tapeworm has part of its life cycle in sheep, and it can infect humans, but only via a dog (or other canid).

The dog ingests tapeworm cysts by eating offal from an infected sheep. These develop into tiny tapeworms in the dog, which reproduce and lay eggs that are passed in the dog’s faeces. These eggs can be accidentally consumed by people, e.g. in dust or on contaminated vegetables.

The cysts can then develop in the organs of humans, causing a severe disease that can be fatal. Treatment generally involves surgical removal of cysts.

Fortunately, during the past few decades the extensive use of allwormer products in dogs and an awareness campaign encouraging farmers to not feed offal has seen the incidence of this disease in humans become rare.

Liver fluke, which affect sheep, goats and cattle, also affect humans if they eat contaminated waterplants, such as water cress.
