Aseptic techniques must be used to reduce the likelihood of bacterial contamination. This usually involves disinfection of working areas, minimising possible access by bacteria from the air to exposed media, and use of flames to kill bacteria which might enter vessels as they are opened.

Why is it important to handle bacteria in aceptic conditions?
So that you don't contaminate your culture with unwanted bacteria.
To isolate certain bacteria from mixed cultures in order to get a pure culture.
And to ensure the bacteria aren't spread outside of a contained environment and to ensure those handling them aren't infected with them.
In a nut shell really, though you could potentially go into more detail. But at GCSE level that shouldn't be necessary.
