Some of the territory in northern Nigeria, which is predominately Muslim, is divided into autonomous emirates led by emirs
Unregulated gold mining was blamed for the presence of high levels of lead in Anka and Bukuyyum in 2010, killing more than 400 people, mostly children.
"We have confirmed that what happened in Anka and Bukkuyum two years back where many people died from a strange disease confirmed as lead poisoning is discovered in Gusau emirate as result of the processing of gold ore within some communities," Danbaba said in the broadcast.
Evidence of lead poisoning was found in four villages, he said.
Danbaba urged residents to report any gold ore processing in their area to government officials, the Daily Trust reported.
