Bacteria

 

          In a recent biology lab we tested many different locations of the college to see where bacteria is most commonly found, and the results were extremely disgusting and very shocking.

          I always knew there was bacteria on almost everything we touched but it really surprised me to see that so many bacterium’s live on a door handle that is barely touched. There are millions of bacteria in the world but not all can live in every environmental conditions, for example bacterium’s found in Antarctica wouldn’t be found in Africa do to the temperature differences.

          In certain foods we eat such as yogurt, cheese and other dairy products contain many different bacterium’s, obviously not the ones found under toilet seats but ones that are edible and can even be good for you. It is really important for these food products to have these kinds of bacterium’s to make them edible and even good to eat.

          The bacteria found in many dairy products are known as cultures and are harmless to the human body, because we eat them every day and rarely get sick. Other bacterium’s that can be very harmful and even deadly is e-coli and salmonella that is found in questionable foods or foods that were produced in dirty areas or infected by animals with viruses.
