Bleivergiftung
There are obvious health risks in the consumption of soil that is contaminated by animal or human feces; in particular, helminth eggs, such as Ascaris, which can stay viable in the soil for years, can lead to helminth infections. Tetanus poses a further risk. Lead poisoning is also associated with soil ingestion, as well as health risks associated with zinc exposure can be problematic among people who eat soils on a regular basis. Gestational geophagia has been associated with various homeostatic disruptions and oxidative damage.
