Carved wine can't be drunk when it expires. When expired food is infected by bacteria, it may also undergo chemical changes, producing aflatoxin, nitrosamines, acrylamide and other substances, leading to chemical poisoning, inducing cancer, cardiovascular diseases and even genetic mutations.

After the food expires, all kinds of microorganisms will continue to multiply rapidly, producing a large number of toxic substances, which will continue to spread to non-corrupt parts. Even if you eat the uncorrupted part, the toxins in it will still pose a threat to the human respiratory and nervous systems.
