the former black heart chicken trafficker gives the live chicken weight, the main way is to hand the corn, the cold powder, the stone and the mud, and the citizens are easy to understand. Now, someone has churned up barite powder (barium sulfate) into paste and poured it into the chicken body to gain weight. Please pay attention - will the "stone chicken" be poisoned? Before
"May 1", the Chongqing Municipal Bureau of industry and Commerce received a complaint from the consumer, saying that after the slaughter of the living chicken in the main market of the main city, it was found that a large number of unidentified substances remained in the digestive tract, and rubbed into powder, and the chicken could not be eaten. According to the inspection and quarantine technical center of Chongqing entry and exit inspection and Quarantine Bureau, the main component of the unidentified substance in the digestive tract of the "stone powder chicken" is barium sulfate (commonly known as barite powder) with a content of 66.63%, and the content of magnesium in the chicken per kilogram reaches 110 Mg and the barium content is 1.1 mg.
in the early morning of May 8th, the Chongqing Municipal Bureau of industry and commerce, with the support of the public security organs and the highway law enforcement team, found a case of adding minerals to the sale of a living chicken in the Banan toll station of Chongqing and Guizhou high speed, and found thousands of chickens suspected of pouring barite powder.
people think that pouring barite powder to the live chicken is mainly to gain weight, and to make profits illegally, more than the means of water injection and waterfowl, the means of "stone chicken".

what is this barite powder? What is the consequence of human consumption?
the answer in the Baidu phrase is this, barite is also known as natural barium sulfate, and barite is used for oil, chemical, paint, and oil. 80% of the industrial sectors, such as fillers, are used as mud weighting agents in petroleum drilling. At the same time, it can also produce lithopone or X - ray shielding agent in medicine, atomic energy industry, vehicle brake material, packaging belt, high-grade paint, hospital radiation protection wall and other industries.
barite is barium sulfate, which is an important mineral for the production of barium and barium compounds. It contains about 65.7% barium sulfate and 34.3% of three sulfur oxides. Professor Hao Fengtong of the occupational disease and toxicology Department of Beijing Chaoyang Hospital affiliated to Capital Medical University said that as early as the middle of nineteenth Century, people began to use barite as the filler of paint. Since this century, barite has become the main raw material for making various barium chemical products. Since barite is more important and chemically stable and insoluble in water and acid, it was used as an additive in oil and gas drilling mud as early as 20s. Barium sulfate is used to produce white pigment and can be used as filler and coloring agent for rubber.
[b] barium sulfate is a kind of contrast agent [/b]
"barium sulfate is a kind of contrast agent in medicine, that is barium meal, which is basically non-toxic to the human body, but must be used under the guidance of a doctor." Hao Fengtong explains that when people are suspected of having gastrointestinal diseases, doctors often advise patients to do digestive radiography, and the toothpaste like contrast agent swallowed by the patient is barium sulfate. "Improper use of barium sulfate may be harmful to health, such as food may cause intestinal obstruction, inadvertent inhalation of the trachea may lead to interstitial granuloma of the lung, and a large number of barium sulphate spills into the peritoneal cavity can lead to small intestinal necrosis."
[b], since people can swallow barium sulfate, will the "stone chicken" be toxic? [/b]
"the barium sulfate contrast agent used by the patient has reached the standard of medical purity, while the barite powder perfused by the live chicken or the state of the ore stone." Hao Fengtong believes that in nature, barium carbonate minerals, which are often symbiotic with barite, are called heavy stones. The physical properties of the two minerals are very similar, and the chemical properties are different. It has been known that the toxicity of barium compounds to humans depends on their water solubility. "Barium sulfate is nontoxic in its insoluble barium compounds, and barium carbonate in the poison stone is not soluble in water, but it can produce barium chloride after the reaction with gastric acid, which produces potential toxicity." Hao Fengtong stressed.
[b] soluble barium salt caused human death [/b]
"soluble barium salt" belonged to muscle poison. After entering the human body, it stimulates and stimulates skeletal muscle, smooth muscle and myocardium. Hao Fengtong revealed that the acute intoxication of oral soluble barium salt began to appear in the gastrointestinal tract, such as the mouth, throat and esophagus, such as dry and cauterization, as well as headache, vertigo, diplopia, tinnitus, numbness around the lips, and prickle pain. When the myocardium is toxic to the soluble barium salt, the stress and conductivity of the myocardium can be changed and the cardiac tachycardia, premature beat, arrhythmia, blood pressure rise, mental disorder, and the decrease of blood potassium appear. Serious poisoning can lead to heart block, ectopic rhythm and ventricular fibrillation, and patients can die of cardiac arrest.
chronic intoxication is characterized by extreme weakness, dyspnea, saliva, inflammation of the mouth mucus, ophthalmic colitis, indigestion diarrhea, gastric bleeding, arrhythmia, tachycardia, elevated blood pressure, and dysuria. Sometimes there are hair and eyebrows falling off. Frequent exposure to barite dust may cause pneumoconiosis.
Hao Fengtong believes that for every live chicken with barite powder to increase hundreds of grams of weight, and to ensure that the chicken is not accidental, the offender must have done pre research and observation.
[b] three ways to distinguish "stone powder chicken" [/b]
at present, there are mainly two kinds of live chicken in the farm market. One is the chicken, which is kept by the farmers for more than 150 days, which is pure native chicken; the other is the high density breeding in the chicken house, and the fowl which is in the column for about 80 days. Native hybrid chicken is a cross breed of native chicken and fast growing chicken. The main ingredient is feed.
in order for the public to avoid eating "stone chicken", experts say that the following methods can be used when buying a live chicken:
touch: the public can first discriminate when choosing the chicken, and if the feeling of touching the chicken crop is like kneading the mud, then be careful.
look: from the appearance, the head of the turkey is small, the body is compact, the chest and leg muscles are strong, the foot rod is long, and the claw is thin. Because of the long growth cycle, the big toe is well developed, and the chicken crown is large and upright, and the color and lustre are bright. The head and body of the non - native chicken are large, the chicken feet are very thick, the feathers are looser, the cockscomb is small; the big toe is almost undeveloped because of the shorter growth cycle, and looks like a small fleshy mass. Some unscrupulous traders, in order not to let the experienced citizens touch them, will put some corn kernels in the chicken feed to deceive you. At this point, you can also judge by observing. If you put the "stone powder chicken" in a cage, you will find that the stone powder chicken is too heavy because of the chicken crop.
say: if the result of weighing is very different from your visual estimation, you should pay attention to it. At this time, you can choose the slaughter in the field and open the chicken crop, all at a glance.
