The Wall Street Journal article noted “In the first comprehensive study of the DNA on dollar bills, researchers at New York University’s Dirty Money Project found that currency is a medium of exchange for hundreds of different kinds of bacteria as bank notes pass from hand to hand.”
“In the first genome study of the DNA on money, NYU researchers identified 3,000 types of bacteria on a set of one-dollar bills collected in New York.”
“Easily the most abundant species they found is one that causes acne. Others were linked to gastric ulcers, pneumonia, food poisoning and staph infections, the scientists said. Some carried genes responsible for antibiotic resistance.”
“The DNA was as diverse as New York. About half of it was human. The researchers found bacteria, viruses, fungi and plant pathogens. They saw extremely minute traces of anthrax and diphtheria. They identified DNA from horses and dogs—even a snippet or two of white rhino DNA.”
“Their unpublished research offers a glimpse into the international problem of dirty money. From rupees to euros, paper money is one of the most frequently passed items in the world. Hygienists have long worried that it could become a source of contagion.”
