Method for cleaning fresh animal liver, removing toxic matters in fresh animal liver and keeping cell tissue in fresh animal liver fresh

The invention relates to a method for cleaning a fresh animal liver, removing toxic matters in the fresh animal liver and keeping cell tissue in the fresh animal liver fresh. The method comprises the following steps: rapidly taking an intact fresh liver from the body of an animal, cutting off the gallbladder in the fresh liver and preserving a first hepatic portal inner blood vessel; carrying out rapid dissection, finding out a portal vein, a biliary tract, a hepatic artery and the upper and lower ends of the inferior vena cava, and inserting disinfected medical conduits into the portal vein, the biliary tract and the hepatic artery vessel; filling the conduits with perfusion liquid, allowing the perfusion liquid to fully enter the blood sinus system of the liver via the portal vein and the hepatic artery, continuously discharging macrophages and other immune cells containing a great number of toxins, blood and harmful substances, and discharging bile via the biliary tract system; and when the fresh liver turns white from blood red, taking off the conduits, thereby finishing treatment of the liver. The animal liver treated by using the method is maximally prevented from damage to the cell tissue of the liver, and can remove toxins, blood and harmful substances in the liver, which guarantees safety in subsequent eating of the liver.
