Scientific rumors:

The body structure of living things is determined by genes. In the life of an organism, both DNA and chromosomes may mutate, which will be repaired if it is not serious, and will cause pathological abnormality or even death if it is serious. Such a great change in the number and shape of limbs will inevitably involve many serious mutations. This individual basically had no hope of being born and died in the "egg" at the early stage of embryonic development. Even if it survives, it is a big problem whether this trait can be stably inherited to form large-scale farming.

Similarly, artificially modified genes also face the same problem. On the one hand, short-term genetic changes will make individuals unable to survive. Second, with the current technology, it is impossible to achieve such precise and perfect fixed-point conversion. If someone really succeeded in creating a multi-winged and multi-legged individual, and let this feature be stably inherited to form a breeding scale ... Such a major research achievement has caused a sensation in the entire scientific community, how can it finally be called a profiteer on the Internet?

If we insist on finding a possibility, it is not impossible in theory to start with early embryo transfer. Since it was discovered in 1980s, people have been devoted to the research of stem cells in disease prevention and organ transplantation. But so far, this technology has not reached the level of cloning whole organs or parts of organs (such as wings) and then implanting them into individuals. However, cell transplantation is the main means, which is still immature.

To sum up, it is difficult to create such individuals as multi-winged and multi-legged chickens at the current technical level. And these methods, which greatly increase the cost and cannot guarantee success, are believed to be not adopted by profit-oriented businesses.

Media witness:

A few years ago, there were rumors about KFC's "multi-winged strange chicken", accompanied by absurd pictures of PS synthesis. In this regard, KFC quickly stated that KFC attaches great importance to food safety, and all the chicken raw materials used are from domestic suppliers with a certain scale and good reputation. The rumors circulating on the Internet have no scientific basis.

After that, the rumor was almost forgotten by everyone, but after entering 2008, the rumor of KFC's "strange chicken" reappeared on various websites and forums, and was reprinted by netizens. The compiled content and pictures are even worse, confusing the audience and causing trouble to some consumers. This incident was counted as "eight outrageous events in 2008" by the Legal Evening News, and the rumor of KFC's strange chicken was broken.

Then, from a rare humorous angle, Beijing TV made a ridiculous rumor for this incident. From the bizarre incident that a funny hen turned into a rooster, this paper questioned the wave of public opinion that KFC used mutant chickens on the Internet. Finally, after consulting experts, a true and credible argument was obtained: mutant chickens did not exist at all.

20 1 1 On May 29th, 2008, China Animal Husbandry Association also organized everyone to "walk into the production site to witness food safety", so that what you see is what you believe: lead more than 80 media in China to visit the chicken supplier of KFC-Hebei Luanping Huadu Chicken Factory to witness the truth together!

In view of the current public concern about food safety, Dong gave three suggestions. First of all, the publicity and education of food safety in the whole society needs the participation of government departments, industry associations and enterprises, as well as the participation of the media. At the same time, government departments have strengthened supervision over all aspects of food safety. We should also strengthen the improvement of food safety laws and regulations, especially the establishment of "safety standards".

The reporter also interviewed Mr. An, the spokesman of KFC in Nanjing. Mr. An said that this rumor of KFC has a long history. It caused a sensation on the Internet every time, but in fact, all the raw materials used by KFC's 3,200 stores in China came from more than 30 breeding bases in China. These breeding bases are approved by the state and have legal procedures.

20 1 1 September, Baby Tree, the largest maternal and child website in China, and KFC jointly organized a trip to explore the origin of Beijing Huadu Chicken House, which reassured the mothers of KFC's strange chickens.

Netizen rumors:

There have been many bizarre rumors about mutant chickens on the Internet, and some people even used graph software to "create" various mutant chickens. In fact, users with a little drawing experience can easily find that this PS technology is actually very rough, and it is easy to see that the other two pairs of wings are just copied and pasted, as shown in the figure.

The whole process only takes 10 minutes, but the chicken safety panic caused by the pictures is quite huge. Rumors stop with wise men, and only by keeping a clear head and laughing off such rumors with a scientific attitude.

Proverbs 2: Hairless chicken

Hairless chickens do exist. Israel hairless chicken is not a rumored mutant chicken breed bred by acquired hormones, but a new artificial chicken breed produced by genetic mutation and acquired artificial mating, and its nutritional value is no less than that of any normal chicken breed.

65438-0954 hairless chicken with gene mutation was found in the United States. Israeli researchers developed this red hairless chicken after mating hairless chicken with ordinary chicken, and the success rate was 100%. It is said that this time it has something to do with global warming. Raising chickens in the Middle East and Africa requires a lot of energy. Normal chickens need room temperature of about 265,438+0 degrees to grow healthily, while hairless chickens don't need to turn on the air conditioner or pluck their hair when they are raised at room temperature of 365,438+0 degrees. So far, this laboratory has eaten more than 1000, which is delicious and safe to eat.

In the process of species evolution, there are often many "incredible" examples. In the theory of evolution, there is a saying that land animals evolved from aquatic animals. When you first learned that fish grow feet and gradually come to live on land, was it hard to accept, but it was the choice of nature. The same is true of hairless chickens. In order to adapt to the long-term hot climate in some areas, artificial mating and reproduction accelerated its evolution to a certain feature.

Scientific rumors:

A famous popular science website in China, Shell Network, made a special topic for hairless chickens:

Are there really hairless chickens? Yes, it existed as early as 10 years ago. It is not surprising that videos of hairless chicken farms are circulating on the Internet. This not-so-beautiful poultry is actually a hybrid product. Avigdor Cahaner, an Israeli scientist, is the "father of hairless chicken". He crossed a chicken with hairless neck at birth with an ordinary broiler and obtained this fast-growing and low-fat variety.

In addition to the above advantages, hairless chickens were born mainly to cope with the hot weather in tropical countries. Chicken farms need to maintain a suitable temperature (usually around 20℃) to facilitate the growth of chickens. For tropical countries, air conditioning is essential and the cost is increasing invisibly. Hairless chickens are hairless, light in weight and more adaptable to hot climate. In Kahaner's own words, feathers are a waste to some extent, not only wasting electricity to cool down, but also wasting various processes of plucking. From this point of view, hairless fast-growing chickens with low fat content do have certain value in some aspects.

However, hairless chickens have been criticized by many people. According to previous feeding experience, many people point out that hairless chickens are more susceptible to parasites and pathogens. Mosquito bites, wind and sun have also made them suffer enough. In addition, they are very sensitive to temperature changes and will be more affected by sudden weather changes. All these make them pay attention to animal protection.

Regardless of whether this new breed is controversial in animal protection, no research has pointed out that its meat quality is pathogenic. In fact, no matter what kind of chicken it is, as long as it can pass the food safety test and meet the relevant standards, everyone can safely eat it. In addition, fast food suppliers usually adopt the principle of nearby supply. If there are local ingredients that meet the standards, they will buy them locally, otherwise they will buy them in nearby areas. Therefore, consumers in other places should have never eaten hairless chicken except in the Middle East. On the one hand, consumers in China don't have to worry about the safety of hairless chickens, on the other hand, they are unlikely to eat them at home.

Video rumor:

The controversy and panic caused by the hairless chicken video is actually a farce. The video was originally a food curiosity program produced by Fuji TV in Japan. The chicken in the video is not a weird chicken breed produced by mutation or hormone, but a report that Japanese reporters interviewed Israeli scientists to study new chicken breeds, and from beginning to end, the video did not mention that any merchant was using hairless chicken as its main supply chicken breed.

The complete translation of the video is as follows:

Title: Hairless chicken developed in Israel! ?

Reporter: We entered the area marked "No Entry". After opening the door, we went in, but the chickens we saw inside were no different from ordinary ones.

Scientist: This is the chicken under study. Let's look at other chickens.

Reporter: We went in together ... and then we went in. Japanese photographers entered the research area for the first time and saw a very shocking chicken posture:

What's this chicken like? .....

Scientist: We have successfully developed 100% hairless chicken.

Reporter: So, how was this kind of chicken developed?

Scientist: 1954, a kind of chicken with hairless genetic factor was found in the United States, and then this kind of chicken was produced by mating hairless chicken with ordinary chicken. After years of research and development, this 100% hairless chicken was finally made.

Reporter: In fact, this study has a deep connection with global warming.

Scientist: With the intensification of global warming, countries with relatively high temperatures in Africa and the Middle East need a lot of energy when raising chickens.

Reporter: Please look at the following picture: There is no serious problem in raising at a constant temperature of 3 1 degree, and it can be raised without turning on the air conditioner, and the resources consumed by feather depilation are unnecessary.

So, can this chicken with short maturity and no plucking be safely eaten?

Scientist: Actually, so far, we have eaten thousands of experimental chickens. Eating this kind of chicken now is not dangerous to human beings. And compared with ordinary chicken, the meat is softer and tastes better!

Media witness:

Recently, rumors about KFC using illegal hormone chicken are overwhelming. "My friend's father is a senior leader of a certain city of Bank of China, and he has some cooperative relations with KFC in the United States. A high-level leadership exchange visit allowed my friend's father to visit the chicken farm in KFC. This is a place that is strictly confidential to the outside world, and no one can enter it casually ... He said that every chicken has a tube inserted, and it takes two weeks for a chicken to hatch into a finished chicken. Friends, I don't want to say that you know what the test tube lost to them, that is, hormones! Every chicken is completely hairless, just like the chickens we have seen after being cut open and plucked! "

The so-called "visit the chicken farm in KFC" in the rumor is simply nonsense. KFC doesn't have its own chicken farm in the world, and the chicken is provided by a large local broiler breeding supplier.

In August, 2065438+00, a reporter from Shandong Peninsula Network visited and tracked this for two weeks in a row, and made a complete record of the feeding, processing, freight transportation and ingredient distribution of broilers from KFC suppliers. Finally, I learned that the chicken they used was white feather chicken imported from the United States. This kind of chicken has a short growth cycle, rich gravy and low fat content, and has always been the first choice of KFC. It is by no means a variety of bizarre mutant chickens rumored on the Internet.

As one of KFC suppliers, Jiulian Group has strict breeding procedures and serious and responsible staff, which can reassure consumers.

The processing procedure of each broiler is also scientific, rigorous and safe. After the broilers are delivered, they are slaughtered automatically, and then a special working group is responsible for cleaning and cutting. Cutting is also programmed. According to the different cutting parts, it is divided into chicken wings, chicken legs and chicken breasts.

During the visit to the broiler processing plant, the reporter felt the word "regular", and every staff member paid great attention to health and hygiene.
