Eating salted sunflower seeds in the shell after the printed date
Best-by vs. sell-by

Getting to know salted sunflower seeds in the shell
Salted sunflower seeds in the shell sit in the pantry staples section of our food guide. The USDA FoodKeeper database files them under the name “Sunflower seeds (roasted, salted, in shell)”. They fall into the lower-risk group, so storing them well is mostly about keeping quality rather than about safety. Best storage spot: it does not need the fridge; a dark, dry, cool cupboard suits it best.
Foods rich in fat, like butter, nuts, seeds, cooking oils and nut butters, don't support bacterial growth easily, so their main problem is rancidity rather than foodborne illness. Small amounts of rancid fat usually aren't harmful, but they taste bitter and stale. Storing these foods somewhere cool, dark and airtight slows rancidity; the fridge slows it even more.
What makes salted sunflower seeds in the shell spoil
Heat, light and oxygen react with fats and break them down into compounds that smell like old nuts, crayons or paint. Unsaturated fats, the type common in seed and nut oils, turn rancid more quickly than saturated fats such as butter. A knife that carries crumbs or moisture into the tub can also give mold a foothold on butters and spreads.
Mistakes people make storing salted sunflower seeds in the shell

Salted sunflower seeds in the shell: ways to finish them in time

Making sense of expiration dates
The dates printed on salted sunflower seeds in the shell packaging mostly describe quality rather than safety. Under US rules, infant formula's use-by date is the only one federal rules require; manufacturers choose all the others themselves. A “Best if used by” date marks when flavor and texture are at their peak. A “Sell-by” date helps the store rotate its stock, and once it passes you can still keep the food at home for its usual storage time. A “Use-by” date is the manufacturer's own pick for the final day of best quality.
For that reason, the storage times on this page start counting from the moment you open, cook or buy salted sunflower seeds in the shell, not on the date stamped on the package: not needed in the fridge and use-by date in the pantry. Food that was stored properly can still be good after a best-by date, while food that was handled carelessly can go bad long before it.
