PITTSBURGH (KDKA) – Think that fancy five-star hotel you just booked is cleaner than others? According to a new study, think again.

The new study titled “Hotel Hygiene Exposed” finds that the average hotel room has more bacteria than a typical home, airplane, or school.

“We’re definitely not trying to scare anyone,” project manager for Travelmath told Yahoo Travel.

Travelmath used teams of researchers armed with cotton swabs, and plastic bags to test rooms in nine different hotels.

They say they tested three-star, four-star, and even five-star hotels in a variety of locations for the study.

Their results show that all the hotel rooms had a lot of bacteria, and the four-star and five-star hotels actually tended to be dirtier than the less luxurious three-star hotels.

In the Travelmath study, each team swabbed the same four surfaces in each hotel room, the bathroom counter, the remote control, the desk, and the phone.
