Are eggs still safe to eat after 20 days in the fridge?
Eggs can still be safe to eat after 20 days in the fridge, provided they have been stored properly and have not been contaminated. The USDA recommends storing eggs in their original cartons in the coldest part of the fridge, usually the bottom shelf, to maintain a consistent refrigerator temperature. It’s also crucial to keep eggs away from strong-smelling foods, as they can absorb odors easily. When checking eggs for safety, look for any visible signs of damage, such as cracks or breaks in the shell, and check for any unusual odors or slimy texture.
If you’re unsure whether an egg is still safe to eat, you can perform a simple water test to check its freshness. Fill a bowl with cold water and gently place the egg into it. If the egg sinks to the bottom and lies flat, it’s likely still fresh and safe to eat. If the egg stands on its end or floats to the surface, it may be older and less fresh, but still safe to eat. However, if the egg floats to the surface and has a strong, unpleasant odor, it’s best to err on the side of caution and discard it.
How long can I store eggs in the fridge to maintain their nutritional value?
The nutritional value of eggs can be maintained for several weeks when stored in the fridge, provided they are stored properly and handled safely.
