Ian Thompson, professor of engineering science at Oxford, said his team found a piece of paper money in Europe carries an average 26,000 bacteria, while Danish krone were found to have an average 40,266 bacteria and Swedish kroner had an average 39,600 bacteria, The Local.se reported Wednesday. Advertisement Thompson and his fellow researchers said they found the euro was the cleanest of the 15 currencies examined, with an average of just 11,066 bacteria. Thompson said the 26,000 bacteria average for European banknotes is more than enough to pass on harmful infections.
