People may think they touch some filthy surfaces such as public washroom toilets and ATMs, but the dirtiest thing people touch regularly is something every driver does regularly.

A new study by Kimberly-Clark Professional finds that gas pump handles contain the most germs.

"People do not realize the amount of contamination they are exposed to going to work each day and doing everyday things like filling their gas tank or riding on an escalator," says Professor of Microbiology Dr. Charles Gerba in a statement.

Hygienists conducted the test by swabbing surfaces in high-traffic areas in six major U.S. cities and measuring levels of Adenosine Triphosphate (ATP). "Objects with an ATP reading of 300 or higher are considered to have a high risk for illness transmission," reads the statement.
