Rift Valley Regional Commissioner, George Natembeya, on Thursday, August 12 issued the directive after ten people died after consuming suspected adulterated liquor.
Nakuru Health Chief Officer, Dan Wainaina, said the victims were picked from various liquor outlets, with some being in an unconscious stage.
A 36-year-old man and his pregnant wife were part of the ten people that succumbed after drinking the suspected illicit brew.
Nakuru County Commissioner, Erastus Mbui, stated that the tragedy struck just a day after a security meeting was held to address the processing and sale of the illicit brews.
Governor Lee Kinyanjui mourned the death of the 10 adding that the county will intensify the crackdown on the illicit brew dens.
Samples were taken from the bodies of the deceased and the survivors as part of investigations to establish what exactly they consumed.
Cases of people dying after consuming poisonous illicit brew are common in Kenya with similar incidents reported in Thika, Kitui, Kakamega and Nakuru in the past.
In April, eight people died in Kakamega after consuming illicit brew allegedly stolen from one of the dens.
The eight, all residents of Isukha village, died at the Kakamega Referral Hospital while receiving treatment.
Residents noted that all the victims exhibited similar symptoms including severe pain, left-hand swelling, skin peeling off.
