Eggs are typically good for about 3 to 5 weeks after the pack date or expiration date if they have been properly refrigerated at 40°F (4°C) or below. The expiration or "sell-by" dates on cartons are often indicators of quality rather than safety, meaning eggs may still be safe to eat beyond these dates, though their freshness and quality may decline over time

. Key points about egg freshness after expiration:

• Eggs can stay safe to eat 3 to 5 weeks past the pack date or expiration date when stored properly in the refrigerator

• After about 5 weeks, eggs may lose flavor, color, and texture quality, but may still be safe if no spoilage signs are present

• The USDA considers eggs safe for up to 45 days (about 6.5 weeks) after packing if refrigerated

• The "expiration date" is more about peak quality; eggs can often be eaten 2 to 3 weeks past this date safely

• To check if eggs are still good, the float test can be used: if an egg sinks in water, it is fresh; if it floats, it is old and possibly unsafe

• Hard-boiled eggs have a shorter shelf life of about one week after cooking

In summary, eggs stored correctly in the fridge are generally safe to eat for up to 3 to 5 weeks after the expiration or pack date, with quality gradually declining. Always perform freshness checks like the float test and inspect for off smells or appearance before use.
