one year? if kept frozen.

Stilltasty says 2-3 week or the date on the package. You’re well beyond both. I stretch their guidelines but not that much.

I'd throw it out. I've gotten sick too many times from seafood to take a chance

Open it. Smell it. If it smells fine, take a little taste. If your fridge is good and cold, and it's been vacuum sealed, it could be perfectly fine. Like any other packaged food, they put those dates on as a guarantee of quality. It might be mushy or beyond peak flavor. You have to be just as careful with fresh caught fish as with preserved, so make sure it hasn't started to rot, and sniff around for evidence of bad bacteria packaged with it and growing. That's what you have to worry about, rot and bacteria. Check it the same way you would leftovers or any other iffy food. Otherwise, if it smells and tastes good, enjoy it!

Cryovac'd tight, without air/oxygen, I would be fine with it, though into the freezer it would go asap.

I over-shopped during the holidays/New Years. I've been watching similar like a hawk. Most dates are good through Feb. Some taso smoked ham is expensive and came without a date, so into the freezer it went after using a bit. One expensive pack of prosciutto was delivered with a compromised corner of the package letting in air. Into the freezer. (after food savering into smaller packages)

When smoked/cured seafood/meats go off, when oxygen is allowed in, it is obvious. They grow fuzzy mold more often than slimy bacteria. The curing process buys extra time. Not months, but definitely 4-6 weeks if kept cold. And if packaged without oxygen.

Looks great?, smells great?. Fine by me. (smoked/salted, not fresh). Fresh seafood quickly goes into a horrid ammonia smelling nasty zone. Cured smoked is much different than my recent hot smoking. Salt cured is a preservative. I'm smoking fresh, so the usual 2-3 days 'use-by'. After thawing from frozen.

Check also the label and see if nitrate is used for preservative.

Native Americans survived from year to year by smoking salmon and keeping it until the next time the salmon were available. No refrigeration. I'd not be at all worried about it unless it smelled off. Check the package to see if it even required refrigeration before opening. It is sold in gift packs unrefrigerated, in vacuum packed pouches. If that was the source of yours, refrigerating it would extend the life considerably.

I’m not finding a single source that would support it being good. Generally there are varying opinions. In this case the most I’m finding is that it should be ok for a fews days or up to a week past the date, but smell it.

FOAS, any “authority” has to do ass covering and go by the printed dates. People who cook and handle real food everyday know how to check for spoilage. If its not spoiled, it's edible. The makers set their dates WAY early. The date is when they guarantee the contents, with their money behind it, usually also giving you a refund if it goes off before then. If it's been stored properly, there's no reason to think it's not just fine after a month.

I forgot to say earlier that I have experience with this exact thing. Six months after the date it shows evidence of being too old. Probably not make you sick eating it, but not good. Up to three months, perfectly fine.

It was just an observation. You can find plenty of folks saying canned goods are safe virtually indefinitely, cut mold off cheese, eggs good well last their date, etc., but I didn’t run into a single place suggesting unopened smoked salmon would be good that long.

Obviously my internet search doesn’t make me an authority though!

I think eggs are a lot more common. Package dates deification is a bugaboo of mine. Sorry if I came on too strong,

So I'm volunteering myself as an internet person who has opened vacuum packed smoked salmon several months past its date and found it perfectly fine. Too long and it goes mushy and stinky, but that's way in the offing. I really did mean to tell my experience in my first post, but lost it.

As I said....if it's bad you will know as soon as you open it.

I'll let you know as it's quite interesting. If you don't hear from me.......🤢
