Can you still eat salted duck eggs that are six months past their expiration date?

Under normal circumstances, salted duck eggs that have expired for six months should not be consumed. The detailed explanation is as follows:

Salted duck eggs expired for six months are unsafe to eat because the prolonged expiration period likely allows extensive bacterial growth inside, such as Salmonella. Meanwhile, components like proteins and fats gradually break down and spoil, producing harmful substances such as histamine and ketones. Even after heating, these bacteria and toxic compounds may not be completely eliminated. Consuming them can easily irritate the gastrointestinal tract, leading to discomforts such as abdominal pain, diarrhea, and vomiting. In severe cases, food poisoning may occur, posing a threat to health.

In daily storage, salted duck eggs should be kept in a cool, dry place or refrigerated, avoiding direct sunlight and high temperatures to slow down spoilage. Always check the production date and shelf life carefully before purchasing or consuming, and never consume any expired food products. If you notice shell damage, unusual odors, or abnormal appearance of the yolk or albumen—even if the product is within its expiration date—do not eat it, to ensure food safety.
