New Year revellers are being warned to avoid bottles of fake spirits which have the potential to blind or kill people who drink them.
Council trading standards teams urged shoppers not to buy or consume counterfeit drinks if they are looking for cheap deals for celebrations to usher in 2014.
Tests on bottles seized in recent months have found dangerously high levels of methanol - a key ingredient in anti-freeze - among other industrial solvents.
If consumed, side-effects can range from nausea and dizziness to potential blindness and even death.
Shoppers are advised to look out for signs that bottles are not legitimate.
These include unfamiliar brand names, drinks containing sediment, wonky labels, poor quality print, spelling mistakes or bottles on display filled to different levels.
Mehboob Khan, chairman of the Local Government Association's safer and stronger communities board, said: "Everyone wants a bargain at this time of year, but by consuming fake alcohol people may be taking their life into their hands.
"These drinks are often made by organised gangs and may contain all sorts of toxic and dangerous substances.
"Usually, if an offer seems too good to be true then it probably is.
"If anyone is suspicious about a supplier or feels that they may have bought a bottle of counterfeit alcohol, please do not drink it and contact their local council as a matter of urgency."
