Well you can see that a lot of people are concerned, but not I,
that I have seen, has any real reason to believe so. We don't need to
live in a sterile environment. In fact we don't.

OK if you pull it up, you will find DIRT under it. Likely anyway.
Now, go out the front door and look around. Guess what, there is dirt
on the sidewalk, there is dirt under the grass. Get a life. If you
want it cleaned, clean it.

Frankly I would expect carpet that old to be worn and read for
replacement. Yea, I would clean things up before putting new down.
But if the carpet is OK and you don't hate the color or style, I would
sure leave it there.
