Geophagia

From Freepedia

Geophagia is the consumption of dirt. Like Coprophagia, it is dangerous because parasite eggs can be passed in animal feces.

Baylisascaris eggs, for instance, are dropped millions at a time by raccoons and other wildlife. They can stay dormant for years, through extreme temperatures and drought. Some of these roundworm eggs may remain in the soil long after the feces have decomposed, and become active in the digestive tract upon being consumed. Children's predilection to engage in geophagia makes them more susceptible to worm infestations.

Other dangers associated with geophagia include ingestion of sharp objects, such as glass, and a variety of bacteria.

In some parts of the world, geophagia is a culturally sanctioned practice. In Uganda, for instance, earth intended for consumption is available for purchase.
