How long does an egg keep?. Eggs are a staple food in many households around the world. They are versatile, nutritious, and relatively inexpensive. But, how long do eggs actually keep? That's a question visit page many people wonder about when they find a carton of eggs in their fridge that has been sitting there for a while.  The answer to this question depends on a few factors. The first factor is how the eggs are stored. Eggs should be stored in the refrigerator at a temperature of 40°F (4°C) or below. This helps to slow down the growth of bacteria and helps to keep the eggs fresh for a longer period of time.  Another factor that affects how long eggs keep is the age of the eggs when they were purchased. Eggs have a sell-by date on the carton, which is typically around 30 days after the eggs were packaged. However, eggs can still be good for several weeks after the sell-by date, as long as they have been stored properly.  In general, it is recommended to use eggs within 3-5 weeks of purchasing them. After that time, the quality of the eggs may start to decline. The easiest way to check if an egg is still good is to do the float test. Simply fill a bowl with water and gently place the egg in the water. If the egg sinks to the bottom and lies flat on its side, it is still fresh. If the egg stands upright or floats, it is no longer fresh and should be discarded.  It is important to note that eggs should never be frozen in their shells. Freezing eggs can cause the shells to crack and allow bacteria to enter the egg, which can lead to foodborne illness. Instead, eggs can be beaten and then frozen in an airtight container for up to 6 months. This is a great way to preserve eggs for future use in baking or cooking.  In conclusion, eggs can keep for several weeks in the refrigerator if they are stored properly. It is important to check the freshness of the eggs before using them, and to discard any eggs that have gone bad. By following these guidelines, you can enjoy fresh and delicious eggs for longer periods of time.
