DR Elmore, was that sausage raw and uncooked, or the kind that's cooked but you cook it again to heat it up (like, say, Brown 'N Serve)?
If the former, it's a time bomb for sure. But it's probably important for the latter, too, to never be refrozen after thawing.
I don't know if I ever actually suffered from making that mistake, but I know I used to make the mistake. In recent years I've been convinced to just be safe and not sorry.
