Banknotes, coins have bacteria that causes food poisoning: Study


It might be safer to give the right amount of money to food sellers, and not get back any change from them.

A local study has found two types of bacteria on currency notes and coins obtained from a local canteen. The bacteria found are of the S. aureus and B. cereus species, which are among the most common bacteria types that lead to food poisoning.

The canteen cannot be named due to an agreement it has with the researchers.

Ten two-dollar notes, five one-dollar coins and five 10-cent coins were acquired from the canteen on a day in July for the Lifebuoy Germ Protection Study. Conducted by an independent microbiology laboratory, it found both the notes and coins had bacteria, though the amount was not measured.
