Thai authorities were unaware their country had been blamed for exporting cholera to Hong Kong, the Travel Industry Council said yesterday. 'When we raised the issue with the tourist authorities, it seemed they had no idea what was going on,' said council executive director Joseph Tung Yao-chung. 'People in Thailand were unaware of the outbreak in Hong Kong and there were no reports about the disease in the Thai media.' Mr Tung flew to Bangkok on Saturday after 16 holidaymakers who toured the floating market fell sick. He was unable to get in touch with health officials. '[Tourism officials] were very concerned about the issue once we brought it up. They promised prompt action and will reply in a few days,' he said. Mr Tung said hygiene conditions at famous tourist spots such as the floating market were worrying. 'We don't know where the water used to cook noodles comes from but I could see the water was not very clean. 'And we were quite surprised the hawkers selling food in the tourist spots were not licensed,' he said. The council had asked members to advise customers not to eat hawkers' food.
