How Long Do Eggs Last After the Sell-By Date?
*Most eggs are still safe to eat for 3-5 weeks after the sell-by date, provided they have been properly refrigerated. However, quality declines over time, so using them sooner rather than later is always recommended.
Understanding Egg Dating and Safety
Eggs are a staple in many diets, but confusion often surrounds their shelf life and safety. The “sell-by” date stamped on the carton isn’t an expiration date; it’s a guideline for retailers. Understanding how these dates relate to egg safety and quality is crucial for preventing foodborne illness and maximizing value.
The Sell-By vs. Expiration Date
The USDA mandates that egg cartons display a pack date (the date the eggs were placed in the carton) and a sell-by date (a recommended date for retailers to remove the eggs from sale). The sell-by date cannot exceed 30 days after the pack date. Consumers can safely use eggs for 3-5 weeks after the sell-by date, provided they are stored properly. There is no expiration date required by federal law.
Factors Affecting Egg Shelf Life
Several factors influence how long eggs remain safe and fresh after the sell-by date:
- Refrigeration: Constant refrigeration at 40°F (4°C) or below is essential. Fluctuations in temperature can accelerate spoilage.
- Storage: Eggs should be stored in their original carton inside the refrigerator, not in the door. The carton helps maintain a consistent temperature and protects the eggs from odors.
- Shell Condition: Cracked or damaged shells increase the risk of bacterial contamination. Discard any eggs with cracked shells.
Signs of Spoiled Eggs
Even if eggs are within the recommended timeframe, it’s essential to check for signs of spoilage:
- The Float Test: Place the egg in a bowl of water. If it sinks and lies flat, it’s fresh. If it sinks but stands on one end, it’s getting older but is still likely safe. If it floats, it’s likely spoiled and should be discarded.
- Smell Test: Crack the egg into a clean bowl and smell it. A sulfurous or rotten odor indicates spoilage.
- Appearance: Look for discoloration or an unusual texture in the egg white or yolk.
Tips for Extending Egg Shelf Life
Proper storage and handling are key to maximizing the shelf life of eggs:
- Keep Eggs Cold: Refrigerate eggs immediately after purchase and maintain a consistent temperature.
- Don’t Wash Before Storage: Washing eggs removes the protective cuticle, making them more susceptible to bacteria.
- Use Older Eggs for Hard-Boiling: Older eggs peel easier when hard-boiled.
- Freeze Excess Eggs: Crack eggs into a freezer-safe container and freeze them for later use. This is best for whites or yolks separately. Whole eggs can be frozen, but the texture may change.
Egg Safety and Salmonella
Salmonella is a common bacteria associated with eggs. Proper handling and cooking significantly reduce the risk of salmonellosis.
- Cook Eggs Thoroughly: Cook eggs until the whites and yolks are firm. Use a food thermometer to ensure an internal temperature of 160°F (71°C).
- Avoid Raw or Undercooked Eggs: Be cautious when consuming foods containing raw or undercooked eggs, such as homemade mayonnaise or Caesar salad dressing.
- Wash Hands: Wash your hands thoroughly with soap and water before and after handling eggs.
- Clean Surfaces: Sanitize any surfaces that have come into contact with raw eggs.
FAQs: Egg Storage and Safety
How long can eggs sit out at room temperature?
Eggs should not be left at room temperature for more than two hours. After two hours, the risk of bacterial growth increases significantly. Bacteria multiply rapidly between 40°F and 140°F, the “danger zone” for food safety.
Does cooking eggs extend their shelf life?
Yes, cooking eggs significantly extends their safe consumption window. Cooked eggs should be consumed within 3-4 days if stored properly in the refrigerator.
Can I freeze raw eggs?
Yes, but not in their shells. Crack the eggs, whisk the yolks and whites together (or separate them), and store them in a freezer-safe container. Freezing eggs can alter their texture, so they are best used in cooked dishes. Frozen eggs are best if used within 12 months.
What is the best way to store hard-boiled eggs?
Hard-boiled eggs should be refrigerated within two hours of cooking and stored in their shells to prevent drying out. They are best if consumed within one week.
Are brown eggs healthier than white eggs?
The color of the eggshell has no bearing on the nutritional value of the egg. The breed of the hen determines the shell color. Both brown and white eggs are nutritious and safe to consume.
What does the USDA grade on an egg carton mean?
USDA grades (AA, A, and B) refer to the quality of the egg, not its safety. Grade AA eggs have the firmest whites and yolks and are best for frying or poaching. Grade B eggs may have thinner whites and yolks and are suitable for baking or scrambling.
Is it safe to eat eggs past the “use-by” date?
The term “use-by” is less common than “sell-by” but essentially conveys the same type of information. If a carton has a “use-by” date, treat it like a sell-by date; the eggs are typically safe for 3-5 weeks after that date, assuming proper refrigeration.
What happens if I eat a spoiled egg?
Consuming a spoiled egg can lead to food poisoning, which can cause symptoms such as nausea, vomiting, stomach cramps, and diarrhea. Seek medical attention if your symptoms are severe or prolonged.
Can I eat eggs if the shell is dirty?
While it’s preferable to use eggs with clean shells, you can eat eggs with dirty shells. Just be sure to wash your hands thoroughly after handling them and avoid contaminating the inside of the egg during cracking.
How do I know if the eggs in my refrigerator are still good without the carton?
Use the float test and smell test. The float test can give you a good indication of age, and the smell test will reveal if the egg is spoiled. When in doubt, throw it out!
Are pasteurized eggs safer to eat?
Yes, pasteurized eggs have been heated to kill bacteria, including Salmonella. They are a safer option, especially for individuals at high risk for foodborne illness, such as pregnant women, young children, and older adults.
How can I avoid Salmonella contamination from eggs?
- Buy refrigerated eggs.
- Check eggs for cracks before buying.
- Store eggs in the coldest part of the refrigerator.
- Cook eggs thoroughly.
- Wash hands and surfaces after handling eggs.
- Avoid consuming raw or undercooked eggs.
By understanding egg dating, proper storage, and signs of spoilage, you can enjoy this nutritious food safely and confidently.
