Cold-smoked salmon (lox) is not actually cooked and is more perishable than hot-smoked salmon. Treat it like raw fish for storage purposes.

The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.
The Bottom Line
Properly stored smoked salmon stays safe for 5–7 days in the fridge. Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been. Freezing is always an option if you will not use it within the refrigerator window.
