Mingi is the traditional belief among the Omotic-speaking Karo and Hamar tribes in southern Ethiopia that adults and children with physical abnormalities are ritually impure. The latter are believed to exert an evil influence upon others, so disabled infants have traditionally been disposed of without a proper burial. The Karo officially banned the practice in July 2012, while around 50,000 individuals secretly continue to practice it in other Omotic communities.
Among the Karo and Hamar, physically deformed or mingi individuals have traditionally considered to exert an evil influence upon others, so disabled infants have traditionally been disposed of without a proper burial. Such a child was historically killed by forced permanent separation from the tribe by being left alone in the jungle or by drowning in the river.
Reasons for being declared impure include birth out of wedlock, the birth of twins, the eruption of teeth in the upper jaw before the lower jaw, and chipping a tooth in childhood. Some who were separated have been reported to shadow the tribe at a distance until eventually succumbing to hunger or predators.
A feature story in 2011 points out that there has been a dearth of academic scholarship on the subject, but "some observers have speculated that it might have started many generations ago as a way to purge people who are more likely to become a burden or who cannot contribute to the propagation of their people."
The Karo officially banned the practice in July 2012, while around 50,000 individuals secretly continue to practice it in other Omotic communities.
In 2008, Lale Lubuko began rescuing children deemed "mingi." Together with California filmmaker and photographer John Rowe, Mr. Lubuko founded Labuko's Omo Child Organization. To date, this organization has rescued 37 children, ages 1–11 and they live in a home built with the help of John Rowe.

- [The Hamar] believe that evil and bad luck (mingi) exists in certain unholy or impure things. Twins, a child born out of wedlock, a child born with a cleft lip or palate, and children, whose upper milk teeth come before their lower ones, are considered to possess 'mingi and for this reason, they are thrown into the forest to die.
