Trading Standards officers seized 166 bottles of counterfeit vodka from three Luton shops.
A raid on an illicit fsctory in Derbyshire found 20,000 empty bottles, filling equipment and empty cans of anti-freeze.
And fake bottles of Smirnoff found to contain a chemical used in anti-freeze were seized in Weston-super-Mare in Somerset.
In the Luton case, officers removed vodka branded Glen’s and Kommissar from shop shelves after noticing the label on the bottle said “Botteled” rather than “Bottled”. The Kommissar was found to have fake duty-paid labels.
Three samples were found to contain dangerously-high levels of isopropanol, commonly used as an industrial solvent, and butanol which is used in paint remover.
Councillor Aslam Khan, portfolio holder for public health, said: “Drinking these chemicals could cause serious illness or even death in extreme cases.
“Many unsuspecting consumers may think they are buying cheap duty-free alcohol, when they are actually buying fake and dangerous products.”
