Checking rotten eggs is a crucial step in ensuring food safety. Rotten eggs can carry harmful bacteria, such as Salmonella, which can cause food poisoning, so identifying and discarding them is essential. There are several methods for checking the freshness of eggs.
One simple method is the float test. Fill a bowl or glass with cold water and gently place the egg inside. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg stands upright in the bottom of the bowl, it is less fresh but may still be safe to eat. If the egg floats, it is rotten and should be discarded.
