The government announced that from January 1 next year, the import of US pigs and US cattle containing clenbuterol will be relaxed, causing panic among the Chinese. Yang Zhenchang, director of the Department of Clinical Toxicology and Occupational Medicine at Taipei Veterans General Hospital, reminded that ractopamine is a sympathetic stimulant. Pregnant women, young children, and patients with cardiovascular disease should be careful. Most people should have no problem with a normal diet.

Clenbuterol helps pigs and cattle grow meat without gaining weight
In the past few days, many people and groups are worried: Taiwan and many countries have refused to use Clenbuterol for US pigs and cattle for many years. Does it mean that they eat pork containing Clenbuterol? Is beef dangerous? Yang Zhenchang said that clenbuterol is a beta sympathetic receptor enhancer (ß-adrenergic agonist), called "clenbuterol" because it can make nutrients mainly used for muscle growth and less converted into fat, which is eaten by pigs and cattle. Long meat without oil, was invented many years ago as a feed additive.
Early Clenbuterol was easily poisoned, causing tremors and heart palpitations. It is relatively safe "ractopamine". Ractopamine has a sympathetic effect and may cause symptoms such as tremors, heart palpitations, increased blood pressure, anxiety and insomnia. The standard set by the International Codex Alimentarius Commission (CODEX) in 2012 is less than 1 microgram per kilogram of body weight, and it is recommended for adults of 60 kg. Say, the safe tolerance per day is 60 micrograms.
LaiThe metabolism of gdopamine is fast, but young children and pregnant women should be careful
How to quickly metabolize meat containing clenbuterol? Yang Zhenchang said that drinking more water and exercising can not speed up metabolism, but ractopamine is metabolized very quickly in the human body, and 75% of it is metabolized in about 6 hours. Moreover, when assessing the safety of imported clenbuterol pork in the past, Taiwan's dietary intake database for Chinese people showed that the daily intake of ractopamine is 18.3 micrograms based on the daily intake of pork and pig offal. It is fairly safe, but there is still no international standard for the safety of sensitive groups such as children, pregnant women, and patients with cardiovascular diseases, which is more worrying.
Heart disease patients should be 10 times stricter than the average person
especially patients with arrhythmia, the risk of eating foods containing sympathetic stimulants is high. The deceased poison expert Dr. Lin Jieliang believed that the safe tolerance of ractopamine for heart disease patients should be 10 times stricter than that of ordinary people, that is, only 0.1 micrograms per kilogram of body weight, and 60 kilograms of body weight should not exceed 6 micrograms a day. If you eat 18.3 micrograms a day Micrograms exceed the standard by 2 times!
Confinement meals should be avoided due to high visceral residues. According to the Food and Drug Administration’s official announcement today (31), in 2019, the “Eating Meat Exposure Lake” was commissioned by Li Junzhang, director of the Environmental Trace Toxic Research Center of National Cheng Kung University School of Medicine. Health Risk Assessment of Dopamine", the safety assessment result of the general public's consumption of pork is "acceptable risk", but if it is a woman who is confinement, because Chinese people's eating habits of confinement, sesame oil kidney and sesame oil pig liver are a part of diet therapy.Ring, this study shows that if confinement women consume more than 1 piece of pig kidney and 1 piece of pig liver per day, the risk will be exceeded.
Yang Zhenchang said that the residual amount of clenbuterol in meat is low, but the residual amount in internal organs such as liver, kidney and lung is very high. Although there are many people in Taiwan who like to eat kidney beans with sesame oil, they only eat it for a month at most Once or twice, but confinement women often use sesame oil kidneys and pig livers for their daily diet. If they eat pork kidneys and livers containing clenbuterol, they should be careful.
The establishment of allowances for pork liver and kidney causes panic
Yang Zhenchang said that although this time, the lean pork and US beef only mentioned "opening up the import of US pork containing ractopamine and US beef over 30 months old", but did not mention it. To the internal organs, but the allowable amount of pig liver 40ppb and pig kidney 90ppb is set, does it mean that the internal organs of US pigs and US cattle will also be imported in the future? This is what worries everyone.
