Is there an experiment that can test if whether a needle is sterile or not?

I need to choose an experiment for my science project that relates to tattoo, so I chose something like the one I'm asking for. I can't seem to find a website or link to this particular experiment. I need to explain to my science teacher of how to do this experiment, list the materials, and write down the procedure. Ugh! I need help =/
