What’s in Your Wallet? A Whole Lot of Germs

Posted By Candy Sagon On April 25, 2014 @ 3:49 pm In Health Talk | Comments Disabled

Wallet with cash [1]Open your wallet. Pull out a dollar bill. You’ve just touched more than 3,000 bacteria [2] that have been linked to stomach ulcers [3], acne, pneumonia [4] and staph infections.

(Thinking about using that plastic credit card more often now?)

These kinds of microbes, which are found on many surfaces [5], are transferred when we touch things. Money, in particular, gets handed around a lot, say researchers with New York University’s aptly named Dirty Money Project.

The researchers, who are looking at ways disease-causing microbes [7] get spread in our communities, analyzed the genetic material on 80 one-dollar bills that they collected from a Manhattan bank. By using gene sequencing to identify the DNA, they identified many more kinds of bacteria than previous studies in which cells were examined under a microscope.

The results were “quite amazing to us,” Jane Carlton, director of genome sequencing at NYU’s Center for Genomics and Systems Biology, told the Wall Street Journal. [8] “We actually found that microbes grow on money.”

Adding to the problem: People tend to lick their fingers when counting money, she noted. And the absorbent cotton-linen blend paper used to make American bills may act like a germ incubator [9].

That may be why other countries are starting to use a flexible plastic polymer film for their currency. Some studies show the plastic doesn’t retain as much bacteria, although research published last year [11] in the journal Antimicrobial Resistance and Infection Control suggested just the opposite.

Suffice it to say, you need to practice good hygiene habits [12] after handling cash. Wash your hands or use sanitizer. Don’t lick your fingers to count it.

And for goodness sake, don’t put your money where your mouth is.
