1, A: What is clenbuterol? Clenbuterol, whose real name is Clenbuterol Hydrochloride, is an adrenal stimulant and belongs to psychotropic drugs. But what is popular among the people is that any substance or drug that can promote the growth of lean meat and inhibit the growth of fat meat can be called "lean meat". In the early 1980s, a foreign company added it to feed to improve the lean meat rate of pork, but the dosage was usually more than 10 times of the normal dosage to achieve the effect of improving the lean meat rate. Because of the large dose and slow metabolism, pigs are usually raised for a long time, and there are a lot of drug residues in pigs until they are slaughtered and marketed. Entering the human body through food can lead to chronic poisoning. If ingested in large quantities at one time, it will cause acute poisoning reaction, so it has been widely banned. B: Clinical manifestations of clenbuterol poisoning: palpitation, facial, neck and limb muscle trembling, hand shaking and even inability to stand, dizziness and fatigue; Patients with original heart rhythm are more likely to have tachycardia, ventricular premature beats and abnormal ECG; Patients with hypertension, coronary heart disease and hyperthyroidism are more prone to the above symptoms. 2, detoxification and poisoning treatment After a large amount of oral intake at one time, you should immediately gastric lavage, promote the discharge of poisons, and infusion to maintain electrolyte balance. Family first aid should induce vomiting by itself and be sent to the hospital immediately after simple treatment. Cardioprotective drugs should be used under ECG monitoring and electrolyte determination. 3, how to identify the method is "three look at everything": a. Look at the thickness of pork subcutaneous fat. Normal pork has a layer of fat between the skin and lean meat, which is called "pig fat" by the people and is about 1~2 cm thick. However, the fat layer under the pig skin born with lean meat type is obviously thin. Therefore, too little fat is the first warning sign. B.look at the color of the meat. Clenbuterol pork is usually bright red, which is very different from the crimson of ordinary pork. C. look at the interval between fat and thin pork. Normal pork grows naturally, and fat and lean meat are mixed together, while "Clenbuterol" pork has an obvious boundary between fat and lean meat, and there may be yellow liquid flowing out between them. D. cut a piece of meat two or three fingers wide and observe. If pork is soft and can't stand on the box, it may be "lean" pork.
