Eggs are a staple in many kitchens, valued for their affordability, versatility, and high nutritional value. Yet many people feel unsure about whether eggs are safe to eat once the date on the carton has passed. Does the “best-by” date mean the eggs have expired? Or can they still be safely consumed?
The short answer: in many cases, eggs can still be safe to eat after the “best-by” date—if they’ve been stored properly. However, understanding how egg labeling works and how to evaluate egg freshness is key to making safe decisions.
What Does the “Best-By” Date Really Mean?
The date printed on egg cartons often causes confusion. Many consumers assume it indicates when eggs become unsafe to eat. In reality, “best-by,” “sell-by,” or “use-by” dates usually refer to quality, not safety.
For example, a sell-by date is primarily intended for retailers and typically appears within 30 days of when the eggs were packed. Meanwhile, the “best-by” date signals when the eggs are expected to have optimal freshness and flavor.
Food safety experts emphasize that passing this date does not automatically mean the eggs are spoiled. Instead, it indicates that their quality may gradually decline over time.
How Long Do Eggs Actually Last?
When eggs are stored correctly in the refrigerator, they can remain safe for quite some time. According to food safety guidance from the U.S. Department of Agriculture (USDA), raw eggs in their shells can last three to five weeks in the refrigerator.
This means eggs may still be safe even if the printed date on the carton has already passed. Some guidelines also suggest that eggs can remain usable up to four or five weeks beyond the pack date when properly refrigerated.
However, the key factor is proper storage:
- Keep eggs refrigerated at 40°F (4°C) or lower.
- Store them in their original carton to reduce exposure to air and odors.
- Place them on a shelf inside the fridge rather than the door, where temperatures fluctuate more.
Following these storage practices helps maintain freshness and minimizes bacterial growth.
