The mobile phone is probably the object of daily life that we touch the most throughout the day, to the point that we use it while we eat or while we are in the bathroom.
For these reasons, it is known that the screens of our smartphones can host all kinds of bacteriabut now, a study has delved into the subject and the result is terrifying.
the american company SellCell.com has commissioned a study conducted with twenty swabs collected from ten mobile phone screens randomly selected within an office environment.
The sample participants were five women and five men with ages between 22 and 62 years.
Multiple swabs were used for each screen to ensure an accurate sample of bacteria was collected. The swabs were then placed in a developing fluid and sent to a laboratory for bacterial analysis. The results are measured in CFU (Colony Forming Units). Laboratory research was conducted in February 2023.
The data collected through this research offer a picture of the common types of bacteria found on the screens of mobile phones.
Thus, 50% of the phone screens contained the bacteria P. aeruginosawhich is commonly found in cockroach feces.
100% of phone screens contained E.coli and fecal streptococci, both present in human and animal fecal matter, although none of the phone screens contained traces of salmonella.
On the other hand the bacillus cereusresponsible of intense food poisoning, was found on 100% of phone screens, while the S.aureusa bacterium that causes pneumonia, was present on 100% of the sampled phone screens.
