The next time you spend a holiday at a hotel, do not order food in bed. A new study says a bathroom is actually the most hygienic place to eat in most hotel rooms.The research, which included a poll of women travellers, was carried out by the Check Safety First firm that offers health and safety risk management systems to hotels, the Telegraph reported.It said that one in five women suffer from some form of illness during a hotel stay, and blamed it on poor hygiene. It said that as bathrooms are regularly and thoroughly cleaned, they usually contain the least amount of bacteria.

Mattresses and duvets, however, are rarely cleaned, making them among the dirtiest places in the average hotel room.Other places in a hotel room that contain a high level of bacteria were TV remotes, and tea and coffee-making equipment.
