Theoretically speaking, as long as the storage conditions are appropriate, there is no mildew, no odor, no change in color characteristics, and the appearance of the intestine is not damaged and swollen, it is still edible.

However, the shelf life of food is a limited time to ensure food safety. The shelf life is not a fresh-keeping period, and the nutrition and taste during the shelf life will gradually decrease with the passage of time ... For ham sausage, if the time is too long, it may become a sausage with starch and artificial eggs, which is a bit meaty and salty. If there is no reason to eat, it is still recommended not to eat. If you eat, it is safer to cook (not heat) by steaming, frying and frying.

Moreover, foods such as ham sausage are sealed "soft cans" with a lot of antiseptic ingredients added (as long as they meet the requirements, they don't need to be regarded as a scourge ... salt is a kind of preservative), and they are also processed at high temperature and high pressure, even if they exceed the marked shelf life, they are not easy to rot. If it's pasteurized milk, don't eat it once it's expired.
