Last month campaigners and the families of some of the Britons who have died or been injured from methanol poisoning abroad met members of the travel industry and MPs in parliament.
Amanda Dennis represents the family of Simone White, a 28-year-old lawyer from Orpington who was one of six backpackers who died from methanol poisoning in Laos, and was among those urging greater awareness.
"All these youngsters have died unnecessarily, and it could have been so easily avoided if there had been more awareness, if there had been more knowledge, and if they'd had it taught in schools," she said.
Calum Macdonald, 23, from Sunbury-on-Thames, went blind during the same incident, and said: "I think it's important that people know obviously because it's quite a simple bit of information you can get that can really save you a lot of pain.
"I certainly think if I'd been aware of the risks I wouldn't be here today without my vision."
Hamish Falconer, the Foreign Office minister responsible for consular and crisis, said: "Methanol poisoning can kill. It can be difficult to detect when drinking and early symptoms mirror ordinary alcohol poisoning. By the time travellers realise the danger, it can be too late."
He added: "No family should endure what the campaigners' families have suffered. Their determination to prevent others facing the same tragedy has been instrumental in driving forward these vital updates to our travel advice."
