Salted duck eggs are made from duck eggs, which are very delicious and rich in nutrition. However, it should be noted that if the salted duck eggs smell bad, caution is necessary. Generally, to determine whether a smelly salted egg can be eaten, it depends on the situation. It is best not to eat the smelly salted eggs after boiling.

1. There are two situations when the salted duck eggs are smelly.

If it smells bad when it is raw, it can be eaten. If it is cooked and stored for too long, it becomes smelly, it should not be eaten at all, as food poisoning can be dangerous.

2. Observe the degree of smell and distinguish whether it is cooked or not. If it is not cooked, it is just a bit smelly on the outside, and there should be no major problems after boiling. If the cooked egg smells bad, it needs to be checked. If it smells very bad, it is rotten. If it doesn’t smell bad, and there are no black spots or anything when peeled open, there should be no problems.

3. If it has gone bad, it is best not to eat it. The smell of the duck egg is due to the egg being stored for too long or having cracks. As the bacteriocin in the egg white gradually decreases, a large number of bacteria侵入 through the pores of the eggshell or cracks, producing methane, nitrogen, ammonia, carbon dioxide, and other substances, emitting an unpleasant odor. After cooking, the amines, nitrates, bacterial toxins, and other substances in the bad egg still exist, which can cause symptoms such as nausea and vomiting after eating, and eating too much can trigger cancer.
