Are Expired Eggs Safe to Eat? Nutrition and Food Safety Experts Share Important Facts
Nutrition dietitian and child care expert Dr Archita Mahajan, along with international food safety specialists, has shared key information regarding the safety of consuming eggs after their expiration date.
According to Dr Sanja Ilic, Associate Professor of Nutrition and Food Safety Expert at Ohio State University, eggs are generally safe to eat for four to six weeks after being packaged, although consumers often rely on expiration dates as a guideline because the packaging date is usually unknown.
The United States Department of Agriculture (USDA) also states that eggs may remain safe even after the labeled date, provided they are stored properly and show no signs of spoilage.
Do Eggs Become Dangerous Over Time?
Experts clarify that eggs can sometimes be contaminated with Salmonella bacteria, which causes thousands of food poisoning cases every year. However, bacteria do not develop simply because eggs become older.
Dr Sana Mujahid, Manager of Food Safety Research and Testing at Consumer Reports, explains that if Salmonella is not present initially, it will not suddenly appear as the egg ages.
The major exception occurs when the eggshell is cracked, allowing bacteria to enter and multiply. Such eggs should always be discarded.
Signs an Egg Has Gone Bad
Experts warn consumers not to eat eggs that show the following signs:
- Cracked or damaged shells
- Sulfur-like foul smell
- Sticky surface on the shell
- Discoloration or unusual texture
These are clear indicators that the egg is spoiled.
Health Risks of Eating Expired or Spoiled Eggs
Consuming contaminated eggs can lead to Salmonella infection and serious food poisoning symptoms, including:
- Severe stomach cramps
- Nausea and vomiting
- Diarrhea
- Fever
- Weakness and dehydration
- Headache and dizziness
In severe cases, hospitalization may be required.
Safety Tips for Egg Consumption
Experts recommend following these precautions:
- Store eggs in the refrigerator at 33°F–40°F (0.5°C–4°C)
- Avoid eating cracked eggs
- Do not consume eggs with bad odor or slimy texture
- After expiration, eat eggs only if they look and smell normal and are fully cooked
- Avoid raw or half-fried eggs if freshness is uncertain
Egg Quality Declines With Time
Michael Makuch, Chair of Interdisciplinary Food Studies at Johnson & Wales University, explains that egg quality naturally decreases over time. Fresh eggs have a firm, round yolk, while older eggs develop flatter yolks and thinner whites due to weakening protective membranes.
Although older eggs may still be safe when properly handled, fresh eggs provide better taste and texture.
