Abstract
Since we live in an open ecosystem; we always interact with so many different living things and mostly we are not able to see what organism we are interacting like bacteria. Some of these bacteria do not affect human body but some of them can be really harmful for human-being. Most of the foods like vegetables contain bacteria that could be pathogenic and we may be infected because of these bacteria. Even we wash them very carefully; bacteria can locate in our kitchen countertops and can be transmitted to us. So the focus of this study is to find out which type of five different countertops provides the most hygienic environment for mankind. The aim of this experiment is to compare total number of different types of bacteria due to different types of countertops. Since infeasibility to examine every types of countertop in the world, five most common types of countertops which are; granite, laminate, polished chipboard, marble and formica are choosen for the experiment. In this experiment; the mean total number of different types of bacteria that was grown over granite, laminate, marble, formica and polished chipboard is respectively 203.2, 77.2, 76.8, 59.8 and 35.6. So polished chipboard provides the most hygienic environment as a countertop within the group while granite provides the least.
