What happens when you find a carton of eggs in your fridge past its expiration date? Is it still safe to consume them? Let’s crack open the facts.
Understanding Egg Carton Dates
Firstly, it’s essential to understand the different dates printed on egg cartons:
- Sell-By Date: This date tells the store how long to display the eggs for sale. It’s not necessarily an indicator of freshness for consumers.
- Expiration Date (EXP): After this date, eggs are considered less fresh but aren’t necessarily unsafe.
- Best If Used By/Before Date: This is a quality guideline, indicating when the eggs will be at their peak freshness and flavor.
How Long Are Eggs Safe to Eat?
Refrigerated eggs can remain safe well beyond the expiration date:
- Freshness Window: Eggs can stay fresh for 3 to 5 weeks after you bring them home.
- Proper Storage: Keep eggs in their original carton and place them in the coldest part of the refrigerator, not in the door.
The Float Test: A Simple Freshness Check
If you’re unsure about an egg’s freshness, try the float test:
- Fill a Bowl with Cold Water: Gently place the egg into the water.
- Observe the Egg’s Behavior:
- Sinks and Lays Flat: The egg is fresh.
- Sinks but Stands Upright: The egg is still safe but should be used soon.
- Floats to the Top: The egg is old and should be discarded.
Why It Works: As eggs age, the air cell inside enlarges, making older eggs buoyant.
Signs an Egg Has Gone Bad
Beyond the float test, look for these indicators:
- Shell Appearance: Cracks or a slimy, powdery coating can signify bacterial growth.
- Egg White and Yolk: Upon cracking, a fresh egg will have a firm yolk and thick white. A watery consistency suggests it’s past its prime.
- Odor: A sulfur-like smell is a clear sign the egg has spoiled.
Risks of Consuming Expired Eggs
Eating spoiled eggs can lead to foodborne illnesses like salmonella poisoning, with symptoms such as:
- Nausea
- Vomiting
- Diarrhea
- Abdominal cramps
- Fever
Safety Tip: Always cook eggs thoroughly to kill any harmful bacteria.
Maximizing Egg Freshness
- Buy Refrigerated Eggs: Ensure eggs are cold when purchased.
- Check the Carton: Look for clean, uncracked shells.
- Refrigerate Promptly: Store eggs at 40°F (4°C) or below.
- Use Older Eggs First: Practice the “first in, first out” method.
Egg Storage Do’s and Don’ts
- Do: Keep eggs in their original carton to protect them from absorbing odors.
- Don’t: Store eggs in the refrigerator door where temperatures fluctuate.
When in Doubt, Throw It Out
If you’re uncertain about an egg’s safety after conducting freshness tests, it’s better to err on the side of caution and discard it.
