The origin of clenbuterol and how to verify it

On March 31st, it was learned from the Provincial Department of Agriculture that in 2015, our province continued to maintain "zero detection" of "lean meat powder" to ensure the safety of agricultural production. Our province recently launched the 2016 "lean meat powder" special rectification work. This rectification focuses on key areas such as feed, veterinary drugs, animal husbandry, procurement and trafficking, and slaughter, with a particular emphasis on monitoring feed products used for pig, beef, and sheep fattening. It particularly crack down on illegal acts of adding prohibited veterinary drugs or other prohibited substances, and increases monitoring efforts on the illegal addition of new "lean meat powder" such as chlorpromazine and bambuterol to veterinary drug products.

Lean meat powder is a common term for beta adrenergic receptor agonists, including over a dozen substances such as ractopamine and salbutamol.

In the early 1990s, "clenbuterol" was introduced to me. In 1999, a pig lung poisoning incident occurred in Gaoming City, Guangdong Province, which caused widespread attention. The Catalogue of Drugs Prohibited for Use in Feed and Animal Drinking Water, released in 2002, explicitly prohibits the use of "lean meat powder" substances such as ractopamine, clenbuterol hydrochloride, clenbuterol, and salbutamol.

News Extension: The United States and Canada have not banned clenbuterol

Expert: Beautiful Canadians basically don't eat pig or cow offal!

Dr. Zhao Zhifeng from the Department of Food Engineering at Sichuan University stated in an interview with reporters that ractopamine belongs to a type of clenbuterol.

I have been banned from using clenbuterol for animal husbandry; Why is it allowed to use clenbuterol ractopamine when feeding pigs and cows in the United States and Canada?

According to reporters, in the early 1980s, American scholars discovered that feeding animals clenbuterol hydrochloride could increase lean meat percentage and feed conversion rate, resulting in significant economic benefits. Thus, Mei began to use it for animal husbandry and gradually promoted it to other households. Later, it was discovered that it had significant toxic side effects, and in the late 1980s, the European Union and the United States successively announced bans on its use.

Subsequently, American pharmaceutical companies developed a less toxic and faster metabolizing alternative, ractopamine. When used, as long as the dosage is strictly controlled and the withdrawal period regulations are followed, there will be almost no residue in the animal body. More than 20 countries including the United States, Canada, and Mexico have approved the use of ractopamine in pig farming.

Lean meat powder accumulates the most in the liver of pigs and cows, while beauties generally do not eat pig and cow offal, but there is a market for internal organs in China. ”Sun Bao, an academician of the Chinese Academy of Engineering in the food industry, said in a media interview that Meiquan is raising pigs on a large scale. A batch of purchase orders came to the farm, and the supply of clenbuterol to these pigs that are about to be sold was stopped half a month in advance. When they are sold, clenbuterol is partially metabolized in the bodies of pigs and cows. It is easy for the government to control the residual amount of clenbuterol. One or two pigs are sampled from a batch, and the whole batch of pigs can be assured. In China, there are countless pigs raised by farmers in free range. If a loophole for clenbuterol is opened, every pig slaughtered must be inspected. Who will bear the cost of the significantly increased meat prices? Therefore, it is correct for me to ban the use of clenbuterol for breeding (personal opinion).
