Up to 51 people have died since Saturday after drinking homemade alcohol in Libya.
Another 300 people are suffering from alcohol poisoning, the health ministry has said.
The consumption and sale of alcohol is banned in the North African country, even though it is available on the black market.
In a statement on its website, the ministry said 38 people had died in the capital, Tripoli.
Another 13 people had died while on their way to Tunisia for treatment.
Libya has seen a significant increase in drug and alcohol trafficking since the 2011 war that ousted dictator Muammar Gaddafi.
