Can I still eat fish maw (fish bladder) if it has gone bad?

Generally speaking, it is not recommended to eat fish maw (swim bladder) that has spoiled. The detailed explanation is as follows:

If the fish maw has already spoiled, it is usually not advisable to continue consuming it. Spoiled fish maw may harbor large amounts of bacteria, mold, and other microorganisms. These microorganisms can break down the nutrients in the fish maw, causing loss of nutritional components and producing harmful substances such as toxins. After consuming spoiled fish maw, these harmful substances may enter the human intestinal tract, triggering digestive tract diseases such as acute gastroenteritis. Therefore, it is not recommended to eat spoiled fish maw.

To avoid the risk of food poisoning, it is recommended to refrigerate or freeze the fish maw immediately after purchase and consume it as soon as possible. Additionally, carefully inspect the condition of the fish maw before consumption, and discard it immediately if any signs of spoilage are found, to prevent gastrointestinal discomfort.

In daily life, attention should be paid to the rationality of food pairing, excessive food intake at one time should be avoided, and a balanced diet should be maintained.
