Think about how many hands the average dollar bill passes through; all jokes about “dirty money” aside, it’s practically impossible for the money that you carry in your wallet to be clean. But some bills are dirtier than others.
Researchers at Oxford put European currencies and banknotes to the test, finding that British pounds are actually cleaner than Euros. On average European bills and coins contain 26,000 bacteria, while UK currency has around 18,200.
How dirty is that? According to Ian Thompson, Professor of Engineering Science at Oxford, 11,000 bacteria is enough to pass on an infection. Makes you want to go wash your hands after paying for your souvenirs doesn’t it?
Surprisingly enough, clean and efficient Scandinavia actually tops the list of dirty cash. The dirtiest currency was the Denmark krone, at 40,266 bacteria, with the Swedish crown at 39,600 not far behind.
Maybe it’s another reason to get behind the Euro?
