A bite of 8,400 bacteria?Eating watermelon infection with H7N9 virus?These rumors are not credible →

Summer is the best season to enjoy watermelon, but it is attentive to those who have ulterior motives to become the protagonist of the rumor.

The Shanghai rumor platform recently received a number of messages, asking whether "watermelon cannot eat with peaches", "one night melon contains 8,400 bacteria", "eat watermelon infection with H7N9 virus" and so on. After verification, the above are rumors, and they belong to the "dead ash".

Analyze the reasons why these rumors spread repeatedly, and do not rule out that some rumors make flows and pull traffic. The rules of the Shanghai rumor platform viewing some social platforms found that when the publisher published the text or short video viewing volume reached a certain number and accumulated a certain fan, the publisher can automatically obtain advertising revenue. Therefore, some rumors use common fruits such as watermelon and other seasons to spread rumors repeatedly, hoping to gain attention. Some rumors will also add "spreading is also a virtue! You can also save your life! Whoever moves your fingers for reposting" and other expressions to encourage others to spread rumors.

In this regard, the public should polish to avoid being used by rumors. Relevant platforms must also establish a review mechanism to clean up such repeated rumors from the source and avoid misleading the public.

Watermelon peaches can be poisoned with eating together

The traceability of the Shanghai rumor platform found that "watermelon peaches cannot be eaten together, and it may be fatal" error saying has been circulated as early as 2016.

Wang Silu, a national senior food inspector and the HACCP food system of the People's Republic of China, said that watermelons and peaches would not be poisoned together.

90%of watermelon is moisture, and about 5%of the remaining 5%are sugar substances such as glucose and fructose; about 85%of the peaches are moisture, which contains sugar -containing substances higher than watermelon, about 12%. It can be seen that the material with the highest content of watermelon and peach is moisture and sugar, and does not contain toxic substances; if you eat together, there will be no special chemical reactions, and some toxic and harmful substances will be generated.

It should be noted that although watermelon and peaches are not poisoned, it is not recommended to eat too much. On the one hand, watermelon and peaches have high sugar content, and too much consumption can easily increase the risks of dental caries, obesity, diabetes. On the other hand, watermelon and peaches contain high moisture substances. If you eat too much at one time, the ability to absorb water in the gastrointestinal wall cells is less than the osmotic pressure of sugar in the gastrointestinal, making it easy Tao, which causes diarrhea.

Some people asked: Why did you only have diarrhea after eating a small amount of watermelon or peach? Wang Silu believes that this may be related to the preservation of fruits. Summer temperature is high, and fruits such as watermelon and peaches are easily contaminated by microorganisms such as bacteria during storage and transportation, thereby accelerating corruption and deterioration. If you eat contaminated watermelons and peaches, it is prone to abdominal pain and diarrhea. In addition, individuals are different, and those with weak spleen and stomach may also appear discomfort after eating a small amount of watermelon or peach, but this is not poisoning.

The Shanghai rumor platform also found that the saying of "watermelon and peaches to eat poisoning" is actually the representative of the "food phase" rumors on the Internet. In this kind of rumors, in addition to watermelons and peaches, the protagonist may also be "mushrooms and garlic", "persimmon and yogurt", "durian and milk", etc. It is rumored that these foods can produce toxins together and cause death.

The above combinations were clarified by professionals. They believed that this was interpreted as "food interaction produces toxins" caused by adverse reactions caused by gastrointestinal discomfort caused by some foods, adverse reactions caused by germs, or allergies or allergies. In addition, the "food gram" of the folk often means that when some foods are eaten together, they are slightly affected in nutrients or caused physical discomfort due to large intake. In order to prove this, institutions and universities such as the China Nutrition Society, Lanzhou University, Harbin Medical University and other institutions have also organized volunteers to try the rumored "phase food" for testing. The results showed that there were no adverse reactions and clinical symptoms in the volunteers for 7 days.

Pay attention to the watermelon can be eaten overnight, and pay attention to storage and cutting

Another widely rumored rumor is "Watermelon cannot be eaten overnight, with 8,400 bacteria." This is also an old rumor, and many professionals clarified.

The traceability of the Shanghai rumor platform found that the rumor first came from a misunderstanding of an experiment in the CCTV program. In this experiment, the staff cut watermelon with different tools, including: simply cleaning with meat cutting blade, cut watermelon, and cut watermelon with special blade. Then seal the cut watermelon to keep the plastic wrap refrigerate, and then detect the number of bacteria on the surface of the watermelon. The result is huge.

It is not difficult to see from the entire experiment that the experiment is not used to prove that "refrigerate watermelon cannot be eaten overnight", but to explain that cutting watermelon should use special tools. The purpose of the experiment is to remind consumers to distinguish between knives and chopping boards when the foods that are directly entrance and the ingredients that need to be cooked and re -imported, which is also the basic food safety knowledge.

Ruan Guangfeng, a member of the China Internet Joint Ballad Platform, pointed out that the rumor's "one mouthful contains 8,400 bacteria" is meaningless. "Watermelon is cut into contact with the air. The number of bacteria is much more than 8,400 in the mouth, and in the intestines. "He also said that for infant formulas with strict food safety requirements, the maximum safety limit value of microbial indicators in my country's national standard reached 10,000. /Gram, the number of microorganisms allowed to exist is much higher than "8,400 bacteria", so "not to say the more bacteria are, it must be harmful. The key is to see if there is a pathogenic bacteria." Whether the watermelon can be eaten overnight. The key depends on whether watermelon is polluted by harmful bacteria. If the watermelon is clean, and the watermelon is also used, the cleaning tools and cutting boards are also used, and the watermelon is wrapped in a clean refrigerator with a clean plastic wrap in time. But if the watermelon that is bought back has been cut and there is no obstruction, whether it is placed outdoors or in the refrigerator, even if it is not night, it is not suitable for consumption.

Eating watermelon will not infected with bird flu

"After eating Nanhui 8424 Watermelon, the death of H7N9 virus" is also a repeated rumor. Its initial version can be traced back to 2016, and it has been "iterated" 10 times.

According to the Shanghai rumor platform, the protagonist of the rumor is not only watermelon, but also other agricultural products, including sauerkraut fish, pork, crayfish, bayberry, grapefruit, watermelon, etc.; "CTC5", "BP5" and other fictional names, and there are bird flu viruses such as "H7N9" and "H7N9"; there are also many places or hospitals that claim to be found in the disease, such as "Shaoxing City, Zhejiang Province", "Jiangxi Province Ganzhou City", "Shanghai" The Third People's Hospital of the Municipal People's Hospital, "Sichuan -Sang People's Hospital", "Beijing Shunyi District Traditional Chinese Medicine Hospital", "Shangqiu, Henan", "Huashan Hospital Branch of Baoshan District", "Xinhua Hospital Chongming Branch" and so on.

But it is not difficult to see the rumor, because the rumors are full of vulnerabilities: first, there are no cases similar to death in related areas or hospitals; second, there are no viruses such as "SK5", "CTC5", "BP5", and the relevant names are fictional names. As for "H7N9" and "H7N9" viruses are bird flu viruses, and agricultural products such as watermelon are not host; third, rumors often say that "CCTV program" has been reported, but in recent years, CCTV programs have not reported any reports related to this. Essence

The inspection also found that rumors related to watermelon first appeared in April 2018 and made up for Guo Moumou, a man in Xiayi County, Shangqiu, Henan. The rumor Guo Moumou was detained by the Xiayi County Public Security Bureau for 10 days for fictional facts.

It is worth mentioning that there is a rule that such rumors spread: often spread according to the time of a certain agricultural product. Therefore, the public misunderstands that such rumors are likely to harm the interests of farmers.
