During the Spring Festival, Ms. Wu from Xianning, Hubei, swallowed a fish gallbladder with white wine while making cured fish. Soon she developed symptoms such as vomiting, diarrhea, headache, and dizziness. After being sent to the hospital, her condition deteriorated sharply and she was transferred to Wuhan University People's Hospital overnight.

Doctors found that Ms. Wu had acute renal failure, liver failure, and coagulation dysfunction. Fortunately, after emergency treatment, Ms. Wu was finally out of danger after 3 days and was discharged from the hospital on February 3.

On New Year's Eve, the emergency department of Wuhan University People's Hospital admitted another patient with fish gallbladder poisoning from Xinzhou, Wuhan.

It is understood that Xie, who is nearly 70 years old , swallowed fish gallbladder raw because he believed that fish gallbladder can cure diseases. He then suffered from vomiting and diarrhea. After receiving multiple gastric lavage treatments at a local hospital, his symptoms did not improve significantly, so he was urgently transferred to Wuhan University People's Hospital.

More toxic than arsenic!

Whether eating raw or cooked food, it will cause poisoning

Why does a small fish gallbladder have such great lethality?

Fish gall is the gallbladder of fish, located on the ventral side of the fish's trunk. It is mainly used to hold the bile secreted by the fish's liver and pancreas and plays a role in digestion.

Fish bile contains bile acid, taurocholic acid, hydrocyanic acid, water-soluble sodium cyprinid sulfate, histamine and other toxins. Among them, the most toxic is hydrocyanic acid, which is more toxic than the same dose of arsenic.

These toxins cannot be destroyed by heating, cooking or alcohol, so even if the fish gall is steamed and eaten or fresh fish gall is taken with wine, it may still cause poisoning.

Although not all fish gallbladders are poisonous, the gallbladders of freshwater fish commonly consumed by people, such as crucian carp, black carp, grass carp, carp, silver carp, bighead carp, Wuchang fish, etc., are all toxic. Therefore, the safest way is to avoid eating the gallbladders of all fish.

Fish gallbladders are poisonous when eaten raw, cooked, or soaked in wine. So, what about the gallbladders of other animals?

Doctors remind that snake gall and bear gall need to be specially processed before they can be used as medicine, and must be used under the guidance of a doctor. Do not consume them at will for the purpose of tonic or health preservation.

What are the symptoms of fish gallbladder poisoning?

After fish gallbladder poisoning, the disease develops very quickly, with an incubation period of about half an hour to six hours.

Digestive tract symptoms such as abdominal pain, diarrhea, nausea, and vomiting usually appear first, usually 1-14 hours after taking fish gall.

After a few hours , symptoms such as yellowing of the skin and sclera, fatigue, poor appetite, pain in the liver area, oliguria, anuria, edema of the face and lower limbs, and low back pain may appear.

As the disease progresses, the functions of organs such as the kidneys, liver, and heart are damaged, and multiple organ dysfunction syndrome and shock occur, endangering life.

If swallowed, seek medical attention immediately

After confirming fish gallbladder poisoning, you should immediately seek medical attention and thoroughly wash your stomach or induce vomiting to remove the poison from your body. Under the guidance of a doctor, you can take some medicine or food that can protect the gastric mucosa and delay the absorption of bile.

Patients with severe fish gallbladder poisoning should receive hemodialysis treatment as soon as possible, which can effectively remove toxins from the body in a short period of time and reduce damage to organs.

How to prevent fish gallbladder poisoning?

1. Understand the toxicity of fish gallbladder and do not believe in folk remedies that fish gallbladder can improve eyesight or cure diseases.

2. When slaughtering, be sure to clean the fish gallbladder.

3. If the fish gallbladder is accidentally broken, the fish meat contaminated with bile should be cut off immediately. If the fish gallbladder is contaminated in a large area, it is recommended to discard the whole fish for safety reasons.
