Q: How often should I rotate my egg carton?
A: To ensure even shelf life, rotate your egg carton every week or two, placing the oldest eggs at the front or near the front and the newest eggs at the back.
Q: Can I freeze eggs to extend their shelf life?
A: While freezing eggs can help preserve their quality, it’s not a feasible option for home storage. Commercial egg producers, however, often freeze eggs to extend their shelf life.
Q: What’s the best way to check an egg for freshness?
A: To determine an egg’s freshness, gently tap it on a flat surface. A healthy egg will have no cracks or blood spots, and will sink into the water with the weight of the egg being less than that of water as indicated by buoyancy. If it cracks, it may not be safe to eat, and if water penetrates into the egg through cracks, it might also indicate that the egg is not fresh.
Q: Can I safely store eggs in a thermally-insulated or vacuum-packaged carton?
A: If you have access to this specialized storage and can control the surrounding temperature at 39°F (4°C) or colder, then it is acceptable to store the eggs inside it, though the most ideal way is storing them at 39°F(4°C) in your refrigerator.
Q: Can I safely consume expired or ‘best-by’ eggs?
A: If the egg is not cracked or leaking, and is stored at the correct temperature, you can still consume it after the ‘best-by’ or expiration date. However, it is imperative to check for any noticeable signs of spoilage before consumption.
Q: What’s the ideal storage temperature for eggs?
A: The safest temperature for storing eggs is between 39°F and 45°F (4°C and 7°C) at an approximate humidity level of 70% to 80%.
Q: Can eggs cause foodborne illness if not handled and stored correctly?
A: Yes, improperly handled and stored eggs can lead to foodborne illness from bacterial contamination (e.g. ‘Salmonella,’ which is usually associated with un-cooked or under-cooked eggs)
Q: Can eggs past their ‘best-by’ date develop ‘Salmonella’?
A: The primary reason ‘Salmonella’ is found in eggs is not its date, but rather the handling and care of the egg, and not every egg, regardless of whether it has passed its ‘best by’ date, develops Salmonella. This can still lead to a health issue if consumed by people with weak immune systems, especially children and the elderly.
Q: When should you discard or use an egg with a blood spot?
A: It is generally recommended to use a small, uncracked egg with tiny blood spots on it within 3 to 5 days to avoid the potential risks associated with the presence of blood within an egg. However, in other instances, if there is a significant portion of blood that appears on the white, or when blood spots are combined with other visible symptoms of spoilage like mold or a sour smell, this egg should be discarded.
