What Are America‚Äôs Dirtiest Surfaces?

Jupiterimages/Thinkstock(IRVING, Texas) -- A new survey has exposed the dirtiest surfaces that Americans touch and not surprisingly they are some of the most frequently touched items we come across every day.

The top offenders on the list include gas pumps, handles on public mailboxes, escalator rails, and ATM buttons.  Following closely were items like vending machine buttons, parking meters, and buttons on crosswalks.

The survey was released Tuesday by Kimberly-Clark Professional, a unit of the personal hygiene giant Kimberly-Clark Corp.

Testers drew more than 350 swabs from surfaces in U.S. cities including Atlanta, Chicago, Dallas, Los Angeles, Miami, and Philadelphia, and analyzed them for levels of adenosine triphosphate (ATP), which signals the presence of animal or vegetable bacteria, yeast, or mold cells.

Everyday objects with an ATP reading of 300 or higher are considered to have a high risk for illness transmission, researchers said.

So how many of the germiest surfaces contained an ATP reading of 300 or more?

  • 71 percent of gas pump handles
  • 68 percent of mailbox handles
  • 43 percent of escalator rails
  • 41 percent of ATM buttons
  • 40 percent of parking meters/kiosks
  • 35 percent of crosswalk buttons
  • 35 percent of vending machine buttons

The fact that the top offenders were all in public places and items that people touch on their way to work, in the mall, or on the street came down to one simple fact, the survey’s leaders said: nobody cleans the things that you’re going to touch on a daily basis,” said Dr. Kelly Arehart, program leader of Kimberly-Clark’s Healthy Workplace Project.

Arehart’s colleague at the project, Brad Reynolds, said the solution is nearly as simple as the problem: wash your hands. Germs from people’s hands can transfer seven times before leaving the skin, so people should wash their hands as soon as they get to work and swab their desks frequently with a cleaning product, Reynolds said.

Hospital Privacy Curtains Covered with Germs, Researchers Say

Hemera Technologies/Thinkstock(IOWA CITY, Iowa) -- A new study shows that hospital privacy curtains are full of germs and may give patients more than privacy.

For this study, researchers swabbed more than 40 privacy curtains, twice a week over a three-week period at the University of Iowa Hospital. Their results, presented at an infectious disease conference, showed that virtually all of the curtains were contaminated with bacteria, including the potentially deadly antibiotic-resistant strain know as MRSA.
Some curtains were contaminated with the same germs over and over. Even new curtains became contaminated within a week.
In addition to being difficult to disinfect, most privacy curtains hang for a long time,
The study's authors stress the need to reduce the risk of infecting patients with this bacteria. The first, most practical and inexpensive defense is by making sure health care workers wash their hands between pulling the curtain and interacting with the patient. Second, patients should take an active role in protecting themselves. They should not be afraid to speak up if they notice the doctor or nurse did not wash their hands after touching the privacy curtain.
