Looking through the shepherd's cabbage inside, I found that there are many other kinds of wild vegetables besides shepherd's cabbage.

Lin Xiaoxiao's hand suddenly stopped, took out one of the green wild vegetables with fat leaves, and after careful observation, put it under his nose and sniffed it.

"This is not a shepherd's cabbage, it's a mandala seedling. Lin Xiaoxiao was shocked.

"Isn't it shepherd's cabbage?" Sister Zhao also wondered, she had eaten shepherd's cabbage for decades, could she admit her mistake this time?

If you take a closer look, it is really different from the previous shepherd's cabbage, the leaves of the shepherd's cabbage in front of you are more fat, and the zigzag shape is more flat.

"It's not the same, but the shepherd's cabbage in the field originally looked different, and the vacant land next to the construction site has been idle for many years, so it's normal for the shepherd's cabbage to grow bigger and fatter. Sister Zhao stared at the abnormal shepherd's cabbage that was brought out, and her heart was empty.

"The smell is different. Lin Xiaoxiao picked another leaf and put it in his mouth, and a bitter and astringent taste spread, "The taste is also different from that of shepherd's cabbage, it is definitely a mandala seedling." ”

"What is a mandala?" Sister Zhao asked, she had never heard the name of a wild vegetable like a mandala.

"Mandala is a scientific name, and we often call it a walnut or goldenrod here. ”

Sister Zhao knows the name of goldenrod, a kind of wildflower that blooms on the side of the road, which is white and poisonous and cannot be eaten, but the seedlings of goldenrod have really not paid attention to it before.

Lin Xiaoxiao brought the whole pot of wild vegetables to Li Bai, "Director Li, I think the source of the poisoning has been found, it is a mandala seedling in the wild vegetables." ”

Lin Xiaoxiao picked out the mandala seedlings alone, and after Li Bai observed them carefully, he asked: "Do you know the mandala seedlings?" Ordinary people may recognize the mandala flower, but its seedlings are similar to many wild vegetables, and it is difficult to distinguish them. ”

"Yes, my dad is a high school biology teacher, and he taught me a lot of plant knowledge, this mandala seedling is very common in my hometown, so I recognize that the whole plant of mandala is rich in hyoscyamine and scopolamine, and excessive consumption will cause symptoms of atropine-like poisoning, which is consistent with the symptoms of the workers this time, and the same as what we analyzed in the conference room before we left. ”

Yu Fei heard the discussion between the two, took out the cold salad left over at noon in the cabinet again, and rummaged carefully, but the wild vegetables had completely lost their fresh shape after blanching, and they couldn't tell whether there were mandala seedlings in it.

Although there are no mandala seedlings to be found in the cold salad, according to Sister Zhao's oral statement, the wild vegetables at noon contain a large number of mandala seedlings similar to those of shepherd's cabbage.

As long as the leftover cold mustard greens are taken back to the laboratory for testing, it can be determined.

The cold salad and wild vegetables that had not yet been eaten were all sealed at noon, and the CDC team returned to the CDC.

——

7:20 p.m. that day.

Yunhai Center for Disease Control and Prevention, Emergency Office.

Outside, it's dark, the office is brightly lit, and the emergency team is waiting for the results of the lab's tests.

Everyone was also busy while waiting.

Li Bai is communicating with the laboratory about the progress of the test.

Yu Fei sorted out the photos of the various growth stages of mandala on the Internet, and prepared to do a popular science publicity on the toxicity of mandala.

Gao Meng is communicating with the hospital about the patient's situation.

Zhang Lin and Yang Le were sorting out the flow information of the hospital and the scene, and Lin Xiaoxiao was helping on the side.

When he was about to finish tidying up, Yang Le came to Lin Xiaoxiao's side and asked with a smile, "I haven't eaten at night, are you hungry?"

Lin Xiaoxiao glanced at the time, it was already 7:30 in the evening, and he was a little hungry, "Fortunately, I just need to control my weight recently." ”

"You are so thin, what kind of weight do you control, as long as the news from the laboratory department comes in a while, we will be fine, just go to dinner, and you are welcome to officially join the disease control team as a dispatcher. ”

"Are you sure we'll be fine after receiving the report from the laboratory department?"

Yang Le: "After the previous investigation, the cause of this food poisoning is very clear, the work that should be carried out is carried out in an orderly manner, as long as the results of the laboratory come out and are fed back to the hospital, our work is basically over, so we will not work overtime too late tonight." ”

Zhang Lin: "Yang Le, if you want to take the opportunity to slaughter our head, you can make it clear, why do you want to take Lin Xiaoxiao out as an excuse, how can this kind of overtime meal after work be regarded as a welcome banquet." ”

Yang Le actively explained, "This is just a warm-up for the official welcome banquet, don't you want to have a few more dinners?"

"I mean, do you want to ask Xiaoxiao if you want to?" Zhang Lin looked at Lin Xiaoxiao, who was concentrating on finishing the finishing work.

"Of course I do. Lin Xiaoxiao finished collecting the information, stuck out his tongue, and said with a smile: "You can't miss this kind of good thing like eating and drinking for nothing, but whether you can eat a big meal in the end depends on Director Li's meaning." ”

Several people's eyes brushed on Li Bai.

Li Bai was still answering the phone, his eyebrows stretched.

Yang Le speculated to himself, "It seems that the result is the same as expected." ”

Zhang Lin rarely agreed with Yang Le's point of view, "Well, no surprise, you can leave for dinner in 10 minutes." ”

Three minutes later.

Li Bai hung up the phone and got up to announce, "The results have been sent by the laboratory department just now, and through the gas chromatography mass spectrometer, hyoscyamine and scopolamine were detected in the vomit and blood of the sick workers, and in the cold salad in the canteen of the construction site. The fresh wild vegetable seedlings we brought back from the site canteen were also confirmed to be mandala seedlings. ”

Yu Fei breathed a long sigh of relief, "Sure enough, it was food poisoning caused by eating mandala seedlings." ”

Gao Meng: "Boss, the cause has been found, it's not a contagious disease, then the next step is much simpler, there is no investigation of close contacts, and there is no need to trace the source of poisons, the hospital is responsible for treating patients, can we eat?"

Li Bai glanced at the time, it was already late, it was past dinner time, "It's so late, if everyone is fine, let's go to work together for dinner?"

When Li Bai called just now, he had vaguely heard the group members discussing the issue of eating, and now that there was finally a result, he took the initiative to mention the matter of the dinner.

"Okay, let's go to the private restaurant I said before. Yang Le immediately came to the spirit.

Yu Fei habitually scolded Yang Le, "Our emergency team used to have dinner together, Yang Le, why are you so excited this time?"

Yang Le smiled, "This time is different from before, we have a new member of the emergency team, and she is a beautiful girl." ”
