If you are allergic to various types of germs and is on vacation, then do not turn on the TV or your hotel room lights. Why so? The reason, a new study shows that the TV remote and switch the lights are one of the most contaminated item in the hotel room.

Researchers from the University of Houston took bacteria samples from some of the stuff in 27 hotel rooms in three states in the United States are Texas, Indiana and North Carolina. Previous researchers suspect a toilet and sink the one who has the highest levels of bacteria, but in fact there are other items that have higher levels of contamination of the TV remote and switch on the bedside lamp.

“The hotel room did not have such clean rooms used for the operation,” said researcher Jay Neal, a microbiologist from the University of Houston as quoted by MyHealthNewsDaily.

The number of bacteria on the TV remote does not mean that the hotel room to be more dirty than any house, but no foreign factor in hotel rooms, added Neal. In this study, the research conducted directly by the student Neal Katie Kirsh.

Domestic helpers spent about 30 minutes to clean each room, bright Kirsh. Therefore, if researchers can determine which parts of the hotel rooms of the most contaminated then the cleaning process can be made more effective.

Highest source of contamination was found in a janitor’s cleaning cart, especially on sponge mops and fittings shall be among the hotel cleaning staff. According to the researchers, this could be a problem because it means that the bacteria carried from room to room.

However, cross contamination can still be reduced by replacing the cleaning fluid during cleaning staff shift change, researchers say.

For bed headboards, curtain rods and bathroom door handles, the bacteria it contains the lowest.

The researchers performed the test twice, first with the general method of testing bacteria and a separate test for the bacteria found in many cloriform stools and more frequent cause of disease.

The results, both tests showed that the levels of bacteria in the hotel room 2-10 times higher than acceptable levels of bacteria in hospitals.

“The presence of this bacteria does not guarantee everyone will get sick, but made all the more likely people become sick,” said Neal.
