There is no clear answer to this question because it depends on how fresh and good the salmon is. Typically, raw salmon from your local supermarket can only be stored for only 1-2 days after purchasing. This is because of the long seafood supply chain. The salmon has to be processed overseas before it gets to the store. It can take 20-30 days for the seafood to get to your local store. Unlike the common grocery stores, at Alaskan Salmon, we deliver fresh, flash-frozen seafood to your door. We process our salmon the same day it’s caught by flash-freezing them while they’re still very fresh and avoiding as much handling as possible to keep the quality of the salmon as high as possible. By doing so, your salmon might last about 4-5 days in the fridge with proper storage and handling. , Consume refrigerated leftover salmon within 3-4 days for optimal quality and safety. Check for off odors, textures, or sliminess that may indicate spoilage. When in doubt, throw it out. Discard cooked salmon after 7 days maximum, even if no spoilage is apparent., According to the USDA, cooked salmon leftovers should be eaten within three to four days. However, you can technically store the leftovers for up to seven days tops, although you will be.
