Original title: online shopping "red onion", after eating it, it is hallucinogenic and enters the ICU. Experts remind: toxic fungi should be eaten carefully, and improper cooking will lead to poisoning.
In summer, it’s time to eat mushrooms again. Delicious mushrooms attract the attention of many diners, but there are many kinds of mushrooms, some of which are even toxic. Boletus lanmao, commonly known as scallion, is a famous kind of toxic mushrooms. With the development of online shopping, red onion began to be sold to a wider area, and some people who were not familiar with this fungus bought it to eat, which triggered a poisoning incident. Recently, a netizen was poisoned by red onion and was sent to ICU for two days of hemodialysis before he recovered slowly. Experts say that hallucinations caused by the poisoning of bacteria such as scallion are only a few cases, and more are caused by headaches, nausea and gastroenteritis, which seriously affect work and life, and it is not clear whether there is long-term damage, which is not a "fun" thing. Yang Zhuliang, an expert from Kunming Institute of Botany, Chinese Academy of Sciences, said that in the latest edition of Yunnan Common Poisonous Mushrooms (Poisonous Mushrooms) 2022, red onions have been included in the category of poisonous mushrooms, and it is recommended that they should not be collected, purchased, processed or eaten!
A rescue caused by greed
Out of curiosity, I bought shallots online, but I didn’t feel "amazing" after eating them for two days.
On June 23, 2022, Xiaohong (pseudonym) was completely awake the next day after eating red onion poisoning. Lying in the hospital bed, she found that her memory was blank for several days, and it was only by constantly capturing memories that she pieced together the poisoning experience.
Wild mushrooms in Yunnan have been listed in large quantities recently. When she was playing social software, she saw big data pushing related content. Xiaohong’s family is in Jiangxi, where she doesn’t produce red onions. She only knows that red onions are "green" and belong to a kind of boletus. I heard that they taste particularly good and are the best mushrooms in Yunnan. The merchant put white onion and red onion on a link. She asked the merchant what mushrooms are delicious now. The merchant said that red onion is a little poisonous, but white onion is not poisonous, but the taste of red onion will be better.
On June 17, 2022, she placed an order for two pounds of red onions on the online shopping platform, and the merchant gave a cooking instruction, telling that it would be no problem to cook for more than 15 minutes. At noon on the 18th, she received the goods. The newly acquired fungus was still a little icy, big and fresh. She was particularly proud at that time and felt that she was good at picking, so she bought a good fungus the first time.
At about 5 pm on June 18th, she sliced the red onion according to the strategy, prepared a lot of garlic slices and dried peppers, stir-fried them in a pot for 10 minutes, and then boiled them in water. She was a little scared and deliberately cooked for more than 10 minutes, and the total processing time was 26 to 30 minutes. When she ate it, she thought it tasted ok, but "it didn’t have that amazing taste."
After eating on the 18th, there was nothing wrong until the afternoon of the 19th, so she did it again in the same way. Because there was a lot of oil left when the fungus was oiled for the first time, she asked the shopkeeper if it could be used. The shopkeeper said that the oil was not toxic and the oil after the fungus was fresher, so she fried and cooked the onion with the previous oil and new oil, and the cooking time was more than 25 minutes.
After being poisoned, he was sent to ICU, and his memory was all blank.
Not long after coming to work in the company the next day, she felt dizzy and sent a message to her lover saying that she might be poisoned. The messages sent afterwards were all typos. She ate red onions with her lover, who was fine. After seeing the news, she rushed over and took her to the hospital around 11 o’clock. As soon as she entered the hospital, she was rushed to the emergency room for rescue, and was pushed out by the nurse wearing an oxygen mask and hanging a drip at one or two in the afternoon. Only when her lover asked did she know that she was really poisoned and had been asking the doctor to see the "villain".
Considering her large consumption and long poisoning time, the doctor decided to adopt hemodialysis treatment. At 6 o’clock that evening, she was pushed into the operating room again, and she didn’t leave the operating room until around 10: 30. "My memory was all blank during this time, and the real memory was at noon on June 21."
Xiaohong’s lover said that on the 20th, his wife vomited from morning till night, and she was unconscious, and she also had symptoms such as vomiting, diarrhea, stomach cramps and colic. Once he was talking to a doctor, Xiaohong reached for the "little man" and dropped the needle on himself. When he came back, he saw that the ground was covered with blood. At that time, Xiaohong’s temper became very violent. "Usually she is very gentle. At the moment she woke up, she found that she had a lot of pipes and needles inserted in her body, so she pulled them all down rudely."
At this time, Xiaohong’s illusion has not disappeared. Many murals and short videos can be seen around curtains and beds, and many cartoon characters look at her through the ceiling and windowsill. She felt very novel and told these things to her family. After Xiaohong’s poisoning, she also showed the symptoms of mydriasis, with serious cross-eyed eyes and double vision. On the afternoon of the 21st, she was pushed to the ICU for the second dialysis, and then her hallucination weakened a little. After dialysis for the third time on the afternoon of the 22nd, the hallucinations and ghosts slowly disappeared.
After leaving the hospital, Xiaohong felt weaker than before, weaker in qi and blood, and more likely to feel sleepy. As long as she hears the name of this mushroom, she will feel sick involuntarily. She once communicated with the merchants about the poisoning problem, and the merchants claimed that her practice was wrong. Because the merchant did warn the red onion beforehand that it was poisonous, she did it completely according to the method said by the merchant, but she was poisoned. I wonder if the merchant should be responsible for it.
What exactly is "red onion"
In 2016, it was discovered that it is an endemic species in China, and its smell is close to that of onion.
Liu Junjie, a doctoral student in ecology at Guangxi University, saw Xiaohong’s photo of red onion and quickly determined its species: Boletus lanmao. He told reporters that Boletus lanmao belongs to a kind of "seeing hands", and red onion is its common name. People used to think that Boletus lanmao was a two-color boletus from America. Later, the team of Yang Zhuliang, a researcher at Kunming Institute of Botany, Chinese Academy of Sciences and a famous mushroom expert, discovered that it was a new genus and new species in China. In 2016, it was published as a new genus and new species under the name of Lanmao, in memory of Lanmao, the name of Boletus and the author of Herbal Medicine in Southern Yunnan in the Ming Dynasty.
The origin of the name "Seeing Hand Green" is that once its thallus is touched, the juice secreted by the pressed contact surface will be oxidized to cyan. In fact, the bacteria not only secrete cyan juice, but also change into powder, yellow, red, purple and black. It is difficult for ordinary people to distinguish their exact species, so they are called red hand, white hand, purple hand and pink hand according to their colors. The light-colored and red Saussurea involucrata, which have the largest harvest, are collectively referred to as onion bacteria by local people, and are divided into two categories: white onion bacteria (light-colored Saussurea involucrata) and red onion bacteria (red Saussurea involucrata). The origin of their names is also very simple-the smell emitted by these bacteria is close to that of onions.
In fact, the red hand also includes several kinds of boletus, and Boletus lanmao is one of them. There are many kinds of gymnosperms, and not all of them are toxic. However, it is well known that Boletus lanmao is toxic.
Can "red onion" be eaten after all?
The mechanism of poisoning is not clear, and toxins may cause damage to internal organs.
Yang Zhuliang told Zi Niu news reporter that Boletus lanmao has been sold in the wild mushroom markets all over Yunnan for generations. Among the wild mushrooms such as Boletus, it is the most expensive one. Locals like to buy, cook and eat, and feel good. Taste good. "But according to our years of research, it is found to be toxic, especially for some susceptible people. If it is not cooked properly, it will lead to poisoning after eating."
How to eat red onion without poisoning? In fact, Yunnan locals are not clear. Some people say that garlic frying can detoxify, and some people say that onion frying can poison. Liu Junjie thinks that there is no scientific basis.
Poisoning by boletus lanmao may lead to hallucinations such as "seeing a villain", which makes some people feel funny and even eat it in pursuit of "seeing a villain". This behavior is extremely undesirable. Like many poisonous mushrooms, different people may have different reactions after eating them. Some people are fine, and some people may have big problems.
Eating red onions without symptoms of poisoning does not mean that its toxins disappeared during cooking and processing. Yang Zhuliang said: "According to our investigation for many years, there is a phenomenon that most people want to make it convenient to eat the leftover red onion dishes before the next time. Put them in the microwave oven for 30 seconds to 1 minute and then eat them, which often leads to poisoning."
Liu Junjie pointed out that there is still a lack of in-depth research on the toxin of red onion, and the specific poisoning mechanism is still unclear. In fact, the illusion of "seeing a villain" caused by eating red onion poisoning is only a few. Its toxin may cause damage to liver, kidney and other internal organs, and more often lead to headaches, nausea, gastroenteritis, vomiting and diarrhea, which seriously affects work and life.
Kunming Institute of Botany, Chinese Academy of Sciences has published a multi-edition illustrated edition of Common Poisonous Bacteria (Poisonous Mushrooms) in Yunnan. Yang Zhuliang told reporters that in the latest edition of Yunnan Common Poisonous Mushrooms (Poisonous Mushrooms) 2022, red onions have been included in the category of poisonous mushrooms, and it is recommended not to pick, purchase, process or eat. "I hope to attract everyone’s attention."
