First of all, what is certain is that green things are by no means green food. Ham sausage is a meat product. If meat rots, it will produce a lot of bacteria and microorganisms, as well as a lot of toxins. After use, it is mild poisoning diarrhea, and what is seriously life-threatening is food. You must not eat expired products again. Even if the quality changes during the shelf life, you can't eat it.

I suggest you don't eat high-temperature ham sausage in the future! Ham is divided into high-temperature products and low-temperature products, and the two production processes are different. The high-temperature products are cooked at a high temperature of 120 degrees, which destroys the nutritional structure of meat. A large number of preservatives are added in the breeding process, so the shelf life of high-temperature ham sausage can reach 120 days to 180 days at room temperature. Think about what meat can last so long? The shelf life of low-temperature products in low-temperature freezer is only about 45 days. Therefore, we must pay attention to buying meat products. The shorter the shelf life, the less anticorrosive components are added.
