The Westin had earlier confirmed that three guests including Frindall, 69, had contracted the disease and that it was trying to establish the source of the infection.
Hussain Nasser Lootah, Director General of Dubai Municipality, said the test results proved that none of the hotel’s guests contracted the disease in Dubai.
“We had taken 24 water samples from different locations at the hotel and all of them tested negative. The hotel had, in fact, conducted its routine tests three times since it opened its doors in May 2008,” said Lootah.
Mr Lootah added that Dubai Municipality conducts periodic lab tests on water samples randomly collected from hotels across the emirate and enforces a strict hygiene and safety code.
“The Westin Dubai hotel had conducted such tests in May, immediately after its opening, as well as in October and December last year and all of them tested negative,” Lootah concluded.
