Commercial smoked salmon is always labeled with an expiration date, so please follow the expiration date, not the three weeks after you buy it.
It is important to check the expiration date carefully, because depending on how the salmon is smoked if there is not enough water in the salmon, the shelf life will be extended.
Storage Period After Opening the Package
If there is any leftover after opening the package, put it in an airtight bag and seal it using a straw or something to remove the airtightly.
Store again in the refrigerator. The shelf life is about 3 to 5 days.
If there is likely to be a lot leftover from the beginning, it is better to store it in the refrigerator instead of on the table, which will extend the shelf life from 3~5 days to 5 days.
Especially at Costco, it is recommended to take out only what you are going to eat and store the rest right away, as they come in large quantities.
