Nairobi, Kenya (CNN) -- At least 19 people died in a Nairobi slum after drinking illegal local brew, which may have been laced with chemicals to make it more potent, a government official said.
An additional 11 more people from the Kibera area are hospitalized, complaining of stomach pains after drinking the brew popularly known as changa'a, said local official Richard Juma.
Police arrested 51 people during a raid for allegedly possessing changa'a, and were being held at a local police station, he said.
"As a government, we are not happy about this incident," Juma said. "We will continue to raid where we think the brew dens are located until this menace is completely done away with".
A sample of the changa'a has been taken to a government chemist for testing.
