Dirty money! Notes and coins crawl with 19 bugs
MAKING contactless payments is meant to be easier than using cash, now it looks like it could be better for our health too.
The cash and coins we carry are covered by up to 19 types of bug and potentially deadly bacteria, experts say.
Our banknotes, coins, purses, pockets and wallets are mostly contaminated by bugs associated with people failing to wash their hands properly after going to the toilet, researchers at London Metropolitan University showed. Polymer £ and £10 notes were contaminated, as were paper £20 and £ 0 notes, by two lifethreatening bacteria associated with antibiotic resistant superbugs – staphylococcus aureus (MRSA) and enterococcus faecium (VRE) and listeria.
Thirty six samples from random denominations of coins and notes were taken by professor of microbiology Dr Paul Matewele and his students. The coins were put in petri dishes and the team watched as bacteria grew over eight weeks in lab conditions. Bacteria was collected from the notes using swabs and grown.
Dr Matewele said: ‘People who have compromised immune systems could be most at risk from handling dirty money. If you’re visiting people in hospital who might be vulnerable to infection, you could unknowingly transfer bacteria off your cash which is resistant to antibiotics.’
