How old is the egg? Do eggs always have to be in the fridge? Which egg do I take for raw food? What does the new, EU-wide uniform producer code mean on the egg? Especially when dealing with eggs in the household, it is necessary to know some rules. Eg eggs may contain or be contaminated with salmonella and, at worst, cause salmonella. Tips for proper handling of eggs in the household.
Chicken eggs can be contaminated with salmonella. In the eggs, an enzyme system first ensures that they can not multiply. After about 10 days, however, this protection system loses its effect. This is the faster the higher the storage temperature and the lower the humidity. Therefore always store eggs in the refrigerator, because at refrigerator temperatures Salmonella can only grow slowly. Do not wash eggs as this will destroy the protective layer on the eggshell.
Keep your eyes open while shopping!
Pay attention to the freshness of the eggs when shopping. If the laying date is printed, this is easy. Otherwise, a best-before date is given. If you calculate 28 days from this date, you will receive the laying date. Eggs older than 10 days should only be eaten well by heating.
For foods that are no longer heated, such as mayonnaise, mousse au chocolat, custard-filled pies or tiramisu, the eggs should be used within the first 10 days. In addition, such foods should be eaten as soon as possible or cooled well. Incidentally, eggs must be refrigerated from the 18th day after laying in the trade.
How do you recognize fresh eggs?
A little trick is enough to distinguish fresh eggs from old ones: in a glass of water, old eggs float upwards, fresh eggs sink to the ground. But even when whipping you can see how fresh an egg is. When the egg is fresh, the yolk is highly arched and the egg white clearly divided into two zones. In a 7-day-old egg, the egg white runs. At least 4 weeks old is an egg when the yolk is flat and the egg white is watery.
Where does the egg come from?
Where an egg comes from, you can tell by the producer code printed on each egg. The first number indicates how the chickens were kept: 0 stands for eco, 1 for free range, 2 for keeping ground and 3 for cage keeping. Then follows the abbreviation for the producer country. DE stands for Germany. The next numbers indicate the laying operation and the house number.
