There are too many variables to give a definative answer to your question, for example. freshness, how dry, how much salt etc. You talking jerky here or a moist hot smoke? I have left smoked salmon in the fridge four 2 weeks or so, but have noticed a fishy kind of taste after that period of time. That's not again precice, just an observation of my particular product. I would recommend Jack Whelan's, Smoking Salmon & Trout as a good referance source. eman
