Nigeria and seven other countries have been added to a UK Foreign Office list warning of the risks of methanol poisoning from counterfeit or tainted alcoholic drinks.

Other affected countries that have warned of potential risks include Ecuador, Japan, Mexico, Peru, Russia, Uganda, and Kenya.

The countries are included in the updated travel guidance following incidents involving Britons in those countries.

The advice previously covered Thailand, Laos and Vietnam, Cambodia, Indonesia, Turkey, Costa Rica and Fiji and followed a number of high-profile incidents, including the death of six tourists in Laos last year.

The UK foreign Office warned travellers to watch out for signs of methanol poisoning such as blurry vision and confusion, which could lead to serious illness and death.

Methanol is an industrial chemical found in antifreeze and windscreen washer fluid. It is not meant for human consumption and is highly toxic.

With instances of unscrupulous backyard brewers adding methanol to drinks to extend their reach, and some bars and street vendors mixing it with spirit-based drinks and cocktails to cut costs, the Foreign Office has said it is crucial to be cautious.

The Foreign Office advised British nationals going abroad to purchase sealed drinks from licensed establishments, avoid homemade alcohol and pre-mixed spirits, cocktails and drinks served in buckets or jugs.

Travellers are advised to watch out for warning signs of poisoning, which include nausea, vomiting, dizziness and confusion.(The Guardian)
