I've taken sliced slami on a number of trips, up to about 5 days I think, with no problems. But never in really hot weather, usually the Sierra in the spring or summer. And that was non-nitrate salami, so less preservatives than most, and it was not very dry salami, either. So I expect most any fairly dry salami with nitrates would do fine for a week or more. If it does get funky, then don't eat it - but make sure you dispose of it FAR away from any campsite!
