Timothy,

No race can "magically" transition from chemical fueled rockets to undetectable, 
stealthy space warp drives instantly. There should be a gradual development 
through a range of different technologies, SOME of which should yield energy 
signatures which we can detect at great distances.

You seem to be thinking biocontamination as in local here on Earth. I meant in
the broader sense of interstellar.
