A series of lead poisonings in Zamfara State, Nigeria, led to the deaths of at least 163 people between March and June 2010,[1] including 111 children.

By 2022, Médecins Sans Frontières stated that conditions had greatly improved after years of a lead poisoning intervention programme.

[1] It was thought by the villagers that all the children had contracted malaria but Médecins Sans Frontières (MSF) found unusually high levels of lead in the blood during tests.

[6] It is hoped that the clean-up can be completed prior to the start of the rainy season in July, which will spread contaminants, though it is being hampered by the remoteness of the villages and Muslim restrictions preventing men from entering some compounds.

[9] The dimercaptosuccinic acid (DMSA) chelation therapy deployed to 3,180 children by MSF is associated with a substantial reduction in the mortality rate of observed and potential lead poisoning cases.
