If your dry salami does not have a "Keep Refrigerated" label, it is a shelf-stable variety. The lack of a label means that if the casing is intact and not cut, the salami can be kept safely unrefrigerated for several years, note Sharon Tyler Herbst and Ron Herbst, authors of "The Deluxe Food Lover's Companion." On the other hand, the U.S. Department of Agriculture recommends that you limit the time on the shelf to six weeks even for uncut salami.
