The most contaminated surfaces in hotel rooms

18.06.2012
An experiment of surfaces in hotel rooms finds television remotes to be among the most heavily contaminated with bacteria and items on housekeeping carts carry the potential to cross-contaminate rooms. Researchers from the University of Houston report the findings today at the 2012 General Meeting of the American Society for Microbiology.

"Hoteliers have an obligation to provide their guests with a safe and secure environment. Currently, housekeeping practices vary across brands and properties with little or no standardization industry wide. The current validation method for hotel room cleanliness is a visual assessment, which has been shown to be ineffective in measuring levels of sanitation," says Katie Kirsch an undergraduate student at the University of Houston who presented the study.

As the public becomes increasingly concerned with public health, hotel room cleanliness and sanitation are becoming consideration factors for consumers when selecting a hotel room. Contact with contaminated surfaces is a possible mode of transmission of illness during outbreaks in hotels. This, combined with the lack of standardization of hotel room cleanliness, poses a risk for hotel guests, specifically immunocompromised individuals who are more susceptible to infection.

"Currently, housekeepers clean 14-16 rooms per 8-hour shift, spending approximately 30 minutes on each room. Identifying high-risk items within a hotel room would allow housekeeping managers to strategically design cleaning practices and allocate time to efficiently reduce the potential health risks posed by microbial contamination in hotel rooms," says Kirsch.

The study was designed as the first step in applying the Hazard Analysis and Critical Control Points (HACCP) system to hotel room cleanliness. Originally developed by the National Aeronautics and Space Administration, HACCP is a systematic preventive approach that identifies potential physical, chemical and biological hazards and designs measurements to reduce these risks to safe levels.

Kirsch and her colleagues at the University of Houston, along with researchers from Purdue University and the University of South Carolina sampled a variety of surfaces from hotel rooms in Texas, Indiana and South Carolina. They tested the levels of total aerobic bacteria and coliform (fecal) bacterial contamination on each of the surfaces.

While some of the most contaminated samples, including the toilet and the bathroom sink, were to be expected, they also found high levels of bacterial contamination on the TV remote and the bedside lamp switch. Most concerning, some of highest levels of contamination were found in items from the housekeepers' carts, including sponges and mops which pose a risk for cross-contamination of rooms. Surfaces with the lowest contamination included the headboard on the bed, curtain rods and the bathroom door handle. The researchers cannot say whether or not the bacteria detected can cause disease, however, the contamination levels are a reliable indicator of overall cleanliness.

Kirsch warns that this study is preliminary and is limited by the sample size, which included only 3 rooms in each state and 19 surfaces within each hotel room, but hopes that it is just the beginning of a body of research that could offer a scientific basis to hotel housekeeping.

"The information derived from this study could aid hotels in adopting a proactive approach for reducing potential hazards from contact with surfaces within hotel rooms and provide a basis for the development of more effective and efficient housekeeping practices," says Kirsch.

Katie Kirsch will participate in a live webcast media availability to discuss her research on Sunday, June 17, 2012 at 2:00 p.m. EDT. The webcast can be found online at www.microbeworld.org/asmlive.

This research was presented as part of the 2012 General Meeting of the American Society for Microbiology held June 16-19, 2012 in San Francisco, California. A full press kit for the meeting, including tipsheets and additional press releases, can be found online at http://bit.ly/asm2012pk.

The American Society for Microbiology is the largest single life science society, composed of over 39,000 scientists and health professionals. ASM's mission is to advance the microbiological sciences as a vehicle for understanding life processes and to apply and communicate this knowledge for the improvement of health and environmental and economic well-being worldwide.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
