Coliform bacteria contamination measurement of cell phones and users' hands
Keywords:
mobile phone, hands, bacteria contaminationAbstract
Several environmental problem and diseases should be faced by mankind nowadays. Some of them are consequences of our high-speed social life. Recently handwashing has got highlight and several diseases could be avoided by it. This study aims to examine the presence of coliform bacteria on the surface of cell phones and the users’ hands, as these devices are essential part of human life now. Association was supposed between the contamination level of the telephone parts and owners’ hands. More than 90% of the samples from the right and left hands were infected by coliform bacteria and 76.1% of the samples from the screen and back mobile phone were infected by coliform bacteria. The percentage of negative cultures from mobile phone was 20.5% (average percent). The negative samples of the right and left hands were only 12% (average percent). It should be emphasized that the present study is only a case study to highlight the problem and to draw attention to the necessity and accuracy of handwashing, but it is not a representative survey.
