Travellers to Thailand are advised about the potential dangers of drinking tap water as the country enters its worst drought in four decades.
A long period without rain fall has led to sea water making its way into the fresh water supply, which is affecting tap water, the Foreign and Commonwealth Office reports.
“This issue may continue for several months,” said the FCO. “Thailand’s Metropolitan Waterworks Authority advise that there is no risk to public health from drinking tap water but salty water can affect people in higher risk groups, such as those with kidney disease.
“If you are concerned about the risks to your personal health, you should drink bottled water and/or get medical advice.”
There have been reports in Bangkok of salt in the tap water, which is believed to have occurred as the city’s Chao Phraya river has become too low to keep sea water out.
