Beware of antibiotics abuse in livestock farming

Not long ago, Yangcheng Evening News published a headline headline entitled "Wow!" The report that BB is all resistant to seven antibiotics: early delivery actually has resistance to seven kinds of antibiotics, including cephalosporin, Taineng, Maspin and Fuxingda. According to another report, a statistics from Guangzhou Maternal and Infant Hospital showed that in the drug sensitivity tests of more than a dozen antibiotics conducted on infected newborns, 70% of the babies developed resistance to one or more antibiotics, and the number and degree of drug resistance were significantly higher than in the past, so that in the past some hospital neonate pediatricians were "not surprised" about it. Relevant experts pointed out that the phenomenon of neonatal drug resistance may be related to the abuse of antibiotics by expectant mothers during and before pregnancy, or it may also be related to their prenatal supplement, and the residues of antibiotics in eggs and chicken soup, pig's foot soup and milk they eat every day.

In the middle of the 20th century, the discovery of antibiotics and the successful synthesis of chemical antibacterial substances were first used in human beings, and then widely used as feed additives, which played an important role in animal health and animal husbandry production. As a preventive drug, its main function is to weaken harmful microorganisms in the gastrointestinal tract, inhibit and kill pathogenic bacteria, enhance disease resistance, prevent livestock disease and plague, make the intestinal wall of animals thin, which is conducive to the infiltration and absorption of nutrients, and improve the utilization rate of feed. increase appetite, at the same time stimulate the pituitary secretion of hormones, promote body growth and development, so as to accelerate the rate of weight gain. Due to the various "benefits" of antibiotics, hormones and other additives, it has become an indispensable "treasure" for many animal husbandry operators. In order to maximize economic benefits, some farmers add antibiotics to their feed to varying degrees. Relevant data show that as long as it is raised by humans, most animals may be fed with antibiotics, including not only animals such as pigs, cattle, sheep, chickens, ducks and geese, but also aquatic products such as fish, shrimp and crabs.

According to the statistics of the World Health Organization in 2001, 90% of the total antibiotics consumed each year are used in food animals, and about 12000 tons and 900 tons of antibiotics are used as feed additives and therapeutic drugs for food animals, respectively. In the treatment of animal diseases, the abuse of antibiotics is widespread. As long as animal disease is found in many animal farms, antibiotics are used first, one antibiotic is not effective, immediately change to another, and often use large doses of antibiotics. Antibiotics are used more widely as feed additives. 6000 tons of antibiotics are used as feed additives in China every year, accounting for 50% of the global use of antibiotic feed additives. One of the serious consequences of antibiotic residues endangering human health and irregular use of antibiotics is to cause bacterial drug resistance, and the speed of drug resistance is much faster than the speed of new drug development, in the long run, it will fall into the situation of "no antibiotics available". Human beings will once again face the threat of many infectious diseases. As a result, since July 1, 2004, the state has stipulated that antibiotics should be purchased by prescription, and the State Food and Drug Administration has also issued a notice on promoting the rational use of antibiotics, calling on the public not to buy antibiotics themselves. Rational use of antibiotics under the guidance of doctors.

"at present, the problem of human abuse of antibiotics has been controlled to a certain extent, but the extensive use of antibiotics in animals has become a blind area of monitoring, and its harm to human health can not be underestimated." During the national "two sessions" held in March this year, Sun Chengyi, deputy to the National people's Congress and vice president of the affiliated Hospital of Guiyang Medical College, said that illegal manufacturers or retail investors in China's aquaculture industry generally use a large number of antibiotics, and the problem of endangering human health should attract great attention from all walks of life.

Relevant people from the National Feed quality Supervision and Inspection Center also pointed out that the extensive use of antibiotic additives by farmed animals for a long time will lead to poorer disease resistance and stronger drug resistance of bacteria in farmed animals. as a result, the drug dose has to be increased when treating sick livestock, resulting in more and more antibiotic residues.

Under the vicious circle, "anti-food" has turned into an "invisible killer" of national health through the dinner table, and the human body has also become a "shelter" for antibiotic residues, and drug resistance has been increasing. In addition, long-term consumption of this "resistant food" may cause some zoonotic disease-causing microorganisms or obviously mutated disease-causing microorganisms to be transmitted directly to humans. In this way, microbes that do not pose a threat to humans can also infect people and cause disease, which is even more frightening if it causes an epidemic between people.
