How long is greak yougart good after the sell by date?

Greek yogurt is typically safe to eat for one to three weeks after the sell-by date if it has been stored properly in the refrigerator. However, its quality may decline over time, affecting taste and texture. Always check for signs of spoilage, such as an off smell, mold, or unusual texture, before consuming. When in doubt, it's best to err on the side of caution and discard it.
