What does the pack say about storage temperature? If it mentions refrigeration, toss it. Cooking does not make unsafe foods safe.

This is not really a duplicate of the other one, because of the specificity. I'd say the rule is, to be safe, throw it away, but consider - if it's fully cooked, vacuum sealed and unopened, and loaded with salt and preservatives (as store bought polish sausage often is), you're probably okay. If it's "fresh"/uncooked, no way.
