Yes, eggs do have an expiry, but it's important to understand that it's more about freshness than a strict "expiration" date.
Understanding Egg Freshness
While eggs don't have a hard "expiry date" like some other products, their quality does decline over time. The reference states that eggs typically stay fresh for 3–5 weeks past the pack date. This pack date is the date the eggs were gathered, cleaned, and placed in refrigeration, not the date you bought them from the store.
Key Indicators of Egg Freshness:
- Pack Date: Look for this date on the egg carton. It's the most crucial indicator of freshness.
- Timeframe: The reference indicates that within 3-5 weeks past the pack date, eggs should remain relatively fresh.
- Declining Quality: After 5 weeks, eggs might start to lose flavor and color, and the texture might change, but may not necessarily become unsafe to consume.
How to Store Eggs Properly
To maximize the freshness of your eggs, follow these storage guidelines:
- Refrigeration: Always store eggs in the refrigerator immediately after purchase.
- Original Carton: Keep eggs in their original carton to prevent them from absorbing odors from other foods.
- Avoid Door Storage: Store eggs on an inside shelf rather than in the door, where temperature fluctuations are more common.
Practical Insights:
- The Float Test: A common method to test egg freshness is the float test. Place an egg in a glass of water. If it sinks and lies flat, it's very fresh. If it stands upright at the bottom, it’s still good but should be used soon. If it floats, it's likely spoiled and should be discarded.
- Appearance: Check the egg for any cracks or damage before using. Also, a runny white and flat yolk often indicate older eggs.
What Happens After the Freshness Period?
While eggs past 5 weeks from the pack date might not be at their peak quality, they might still be safe to eat if they pass the float test and other checks. If the eggs appear normal, they might be suitable for baking or use in recipes where they are cooked thoroughly. However, it's generally recommended to use them before that point to ensure the best quality.
