The addition of organic arsenic in the feed can promote the growth of livestock and poultry, and the red hair is bright. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

The Ministry of Agriculture denied that "pig died of arsenic" rumors of feed additives and then raised concerns - 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

An additive used to promote the growth of livestock has been banned from being added to feed in some countries and regions when it is found to cause harm to livestock poisoning and environmental pollution. Like other chemicals, human understanding of organic arsenic has undergone a process of gradual change. Today, food safety has become a common sensitive word for Chinese people. The overreaction to feed additives caused by dead pigs is the mapping of this panic. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

Dead pig rumors 4C5 China feed industry information network - based on feed, service animal husbandry

The tens of thousands of dead pigs drifting in the Huangpu River once triggered a national conjecture about the cause of death of pigs. Although the official news has repeatedly said that dead pigs are not sick pigs, but belong to "normal death" and "frozen death", the water quality of the water supply has not been affected. But people are not willing to believe that all kinds of conjectures are still circulating in the people. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

Among them, the most widely spread is the saying that "pig died of arsenic poisoning" - the addition of organic arsenic in pig feed can promote the development of pigs, and the red hairs are good to sell, which is good for selling. The price, but the side effect is that arsenic accumulates in the pig's body. Feeding for a long time will increase the mortality rate. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

This conjecture also added a background in current affairs - because the anti-corruption public money to eat and drink, the pork market demand dropped sharply during the Spring Festival, pigs fed arsenic did not go out in time, pigs became a drifting dead pig. The causes and consequences are met, many people read, believed, angry, afraid, and forwarded. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

Some scholars have refuted the absurdity of this statement. For example, the knowledge posts on the introduction of popular science knowledge by Zhu Yiwei, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, were scolded by the eager and angry people: The home has come out to fool people. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

The speculation of "arsenic pigs" is so popular that even the official can't ignore it. The Information Office of the Ministry of Agriculture issued a response on the evening of March 20, saying that the Shanghai Veterinary Feed Testing Institute collected 30 floating dead pigs that were salvaged from the Huangpu River and upstream waters in response to the death pig incident related to the feed additive “arsenic”. Tissue samples were tested for arsenic and no arsenic was detected in all samples. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

At this point, the conjecture of "pig death from arsenic" was falsified. But people have become interested in arsenic: why should it be added to the feed? How many pros and cons will it be? 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

Arsenic- containing additive 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

According to Coptie, arsenic is a quasi-metallic substance that exists in the environment in both organic and inorganic forms. Elemental arsenic is almost non-toxic and arsenic is toxic. Now studies have shown that inorganic arsenic is much more toxic to humans than organic arsenic, and trivalent arsenic is more toxic than pentavalent arsenic. In industrialized societies, inorganic arsenic is ubiquitous, and diets such as grains, vegetables, and beverages are the main sources of inorganic arsenic in the body. Aquatic products have a high total arsenic, but mainly organic arsenic. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

Such a sentence, in the mouth of the non-professional general public, is like a tongue twister, and even more to understand the meaning. In the rumor of "arsenic pigs", the phrase "arsenic is arsenic" makes people easy to understand and easy to remember - it should be said that trivalent inorganic arsenic is arsenic. Therefore, some netizens responded to Zhu Yi’s popular science microblogging: "Do you say that this thing is poisonous?" Which foods contain arsenic? Is it artificially added? How should the people evade? 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

In fact, not too long ago, in June 2011, a number of domestic media also disclosed a news - the US market detected some chicken arsenic. Only when the information is in the tide, the speed we forgot is also amazing. Most people have forgotten this information, and they can't remember the recurring word "Roxasha arsenic" (also written as Roxasha). In order to make the terminology easy to understand, the title of some reports at that time was also directly called the United States found "Frozen Chicken". 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

That year, the US Food and Drug Administration (FDA) found that chickens that used the drug Roxarsone arsenic had significantly higher levels of arsenic in the liver. The test also found that the content of arsenic in chicken breast and chicken leg meat was only one-fortieth of that in chicken liver. Food experts at the FDA say the amount of arsenic found is small and not harmful to health. Pfizer Inc., which produces Roxars arsenic, immediately announced that it has voluntarily suspended sales in the United States since July 2011. Pfizer also said that although the chickens were only tested, they will also suspend the sale of the drug in the pig and turkey markets. The FDA said that if the study finally determines that the drug contains carcinogens, it will order Rousseau arsenic to eventually withdraw from the market. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

At this time, it has been decades since the United States first used Roxars arsenic in livestock and poultry farming. The FDA first allowed Roxa arsenic to be used as feed for chickens in 1964. In 1975, arsenic was proved to be a trace element required by animals. In 1983, it was officially approved as a growth promoter for pigs. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry

On a global scale, arsenic preparations have been approved in many countries in Japan and Latin America. In 1993, China also approved the use of arsenic acid in pigs and chickens in 1996. The "Guidelines for the Use of Feed Drug Additives" promulgated by the Ministry of Agriculture of China in July 2001, the use of organic arsenic preparations of arsenic acid and Roxa arsenic as pharmaceutical additives is permitted. 4C5 China Feed Industry Information Network - based on feed, serving animal husbandry
