Microbes and Money: A New Meaning to the Phrase 'Filthy Rich'

For most, the simple thought of being "filthy rich" makes us quiver in ecstasy--shopping sprees, paying off debts, etc. However, this typically positive phrase also has a negative side. According to a recent study, researchers at New York University's Dirty Money Project found that capitalism's beloved paper currency is also home to hundreds of different kinds of bacteria.  

For the study, researchers analyzed the genetic material found on $1 bills.

Study findings revealed that each dollar bill typically contains 3,000 types of bacteria on its surface. Though most kinds are harmless, according to The Wall Street Journal, DNA drug-resistant microbes have been found on some, along with miniscule amounts of anthrax and diphtheria.

Findings also showed that dirty money could be the cause of common skin problems, particularly acne. Other health issues were further linked, including gastric ulcers, food poisoning, pneumonia and staph infections.

"It was quite amazing to us," said Jane Carlton, director of genome sequencing at NYU's Center for Genomics and Systems Biology where the research was performed, via NPR. "We actually found that microbes grow on money."

As the goal of the study was to push for prevention of future disease outbreaks in New York City before their start, Carlton adds: "We're not trying to be fear mongers, or suggest that everyone goes out and microwave their money," she said, via NPR. "But I must admit that some of the $1 bills in New York City are really nasty."

Researchers conclude the study with the question: Could changing money's material better prevent the passage of disease?
