You may want to pack your hand sanitizer before you head out to the ATM.

New York University researchers took swab samples of 66 ATM keypads from neighborhoods across Brooklyn, Manhattan and Queens and what they found is sure to make you cringe. The study showed the unseen inhabitants including human skin, traces of food, a number of parasites, and species closely related to STD causing trichomonas vaginalis. Most of the bacteria were from the classes Actinobacteria, Bacilli, Clostridia, Alphaproteobacteria, and Gammaproteobacteria – a class known to contain a number of pathogens, such as Salmonella.




ATMs located in particularly in laundromats and stores were rife with Lactobacillales (lactic acid bacteria), which is found in decomposing plants and milk products.

Though samples were taken from both indoor and outdoor ATMs, the report published online in the journal mSphere stated researchers had a difficult time finding a significant difference between the two.

“Our results suggest that ATM keypads integrate microbes from different sources, including the human microbiome, foods, and potentially novel environmental organisms adapted to air or surfaces,’ said senior study author Jane Carlton, director of the Center for Genomics and Systems Biology and professor of biology at NYU. “DNA obtained from ATM keypads may therefore provide a record of both human behavior and environmental sources of microbes.”
