It should be OK to eat but, if I were you I would try to avoid freezing smoked Salmon. Freezing changes to quality. Smoked Salmon can keep in the frig up to 6 month's without freezing. Freezing brings the oils out,clinging to the bag or container, causing it to dry out some and changing the texture. I freeze some myself but this is because, I Smoke a lot of Salmon during the Season and I have to in order to keep it up to a year or until the next season. The Smoked I love best it's the stuff that I keep refrigerated and then eaten. Remember to take the time and let it thaw in the frig and you will have a better product. Enjoy! beer
