Once you open your package of smoked fish, you should consume it all within 5 days. In the rare event of leftovers, store your opened packages in a zip-lock bag to maintain that second-to-none succulence.
Unopened, vacuum-packed fish, including cold-smoked, hot-smoked, and specialty items, will stay fresh and flavorful for much longer. Just check the “best by” date on the label and enjoy before then. Saving your smoked fish for a special occasion? Pop it in the freezer to extend the shelf life for up to 6 months. A thaw in the fridge (set below 40°F) is all that stands between you and a great meal with family or friends.
