The First People's Hospital of Yunhai City, emergency room.

Dozens of poisoned workers were sent here.

The emergency department beds are full, and there are a few patients with mild symptoms in the hallway who are sitting in chairs and playing hanging bottles.

Gao Xiaoming, director of the emergency department, was so busy that when he saw Li Bai and his party coming over, he grabbed Li Bai and complained, "Your disease control is finally here, there are so many people with food poisoning recently, today is a historical record, dozens of workers came together, I just asked a few patients with mild symptoms, they said that they got sick immediately after eating in the canteen of the construction site at noon, and I suspect that it should be chemical food poisoning." ”

Gao Xiaoming introduced the situation and checked the patient's symptoms.

fever without sweating, dilated pupils, and convulsions of the limbs...... Sure enough, they are all symptoms of atropine poisoning, although the symptoms of the patients are mild or severe, but the symptoms of poisoning are similar.

Gao Xiaoming: "I have been treated according to atropine poisoning just now, but the symptoms have not been alleviated, I suspect that it is caused by other atropine alkaloid poisoning, and the treatment plan is being changed, but it is best if your disease control can find out the cause of poisoning as soon as possible." ”

Several members of the emergency response team began to investigate and question dozens of workers one by one.

Lin Xiaoxiao was busy filling out the case flow form.

The inquiries of dozens of people ended within half an hour, and all the case flow tables were concentrated on Li Bai.

All kinds of specimens collected for patients are in Yang Le's on-site sampling box, and according to the previous practice, Yang Le sent the specimens back to the CDC laboratory, and the others went to the construction site.

Before Yang Le sent the specimens away, he routinely asked Li Bai about the scope of testing.

Li Bai: "Tell Section Chief Li that the scope of testing this time is several alkaloids of the atropine category. ”

On the way to the construction site, Li Bai looked through the case questionnaire in the on-site shunting car.

Several people were in the car discussing it.

Yu Fei: "Boss, when I was asking the sick workers just now, I found that they had a limited variety of meals at noon, two vegetarian dishes, two meat and one soup, white rice, and dishes such as scrambled eggs with leeks, cold shepherd's cabbage, stir-fried tea with green vegetables, fried pork slices with potatoes, and radish and tofu soup. ”

Gao Meng: "I specifically asked when I asked, most of the workers have the habit of drinking, but they all drink at night when they get off work, and they don't have the habit of drinking at noon, and they are sure that they don't drink at noon today." ”

Poisoning caused by drinking medicated alcohol can be ruled out.

Lin Zhang: "I asked the patient if he had used atropine Western medicine recently, but so far no one has used it. ”

Li Bai: "Are the staff who cook in the canteen on the construction site there?"

Lin Xiaoxiao: "I heard from the workers that the construction site canteen invited an eldest sister surnamed Zhao to cook three meals a day, and her name was not among the sick people. ”

——

Suburb, construction site.

Due to a sudden large-scale food poisoning incident, the construction site was temporarily suspended.

The person in charge of the construction site was anxious, worried about the progress of the project on the one hand, and worried that the construction site would be responsible for compensation if the worker had an accident, which really compensated the workers and damaged the progress.

The on-site flow shunting of the disease control was parked outside the courtyard wall of the construction site.

Several members of the disease control team carried sampling boxes and work badges into the construction site.

Contact by phone to find the person in charge of the site.

The person in charge is a middle-aged man in his 40s surnamed Zhang, known as Manager Zhang.

Manager Zhang was slightly chubby, his hair was thin, and his face was anxious and ugly because of the food poisoning incident.

Li Bai showed his work card, and a coping smile appeared on Manager Zhang's ugly face.

"Comrades of disease control, our site canteen has always been good in hygiene, there has been no accident before, this time I don't know what's wrong, we invited a special person to cook, the meals are very fresh, and will never be left until the second day to give the workers to eat, I don't believe you can ask Sister Zhao who cooks. ”

"Please take us to the site cafeteria. Li Bai asked.

"Okay, I'll take you there. ”

In the dusty corner of the construction site, far from the center of the building, there are two rows of containers stacked together, which are the dormitories and sheds of the workers.

Next to the dormitory shed is the site canteen.

The so-called site canteen is also a shipping container, with doors and windows, and ceiling fans hanging from it.

There are screens on the windows and curtains on the doors, which are anti-mosquito measures.

There is a faucet outside the cafeteria, and under the faucet is a pool, and next to the sink are two plastic basins, one of celery and the other of unknown wild vegetables.

When I entered the canteen, I found that the sanitary conditions were indeed as Manager Zhang said, although the windows were not bright and clean, but they were also wiped without dust, and the pots and pans were neatly placed.

An older sister in her 40s was sitting in the cafeteria wiping tears from her eyes.

"This is our site canteen, this is Sister Zhao, specially invited to cook for the workers. Manager Zhang introduced.

When Sister Zhao saw someone coming in, she immediately stood up and spoke tremblingly, "My rice is very clean, the vegetables are also clean, the vegetables are bought at the morning market, I don't know why there is a problem." ”

Lin Xiaoxiao subconsciously comforted: "Don't worry, stabilize your emotions, and cooperate with us to answer a few questions." ”

Lin Xiaoxiao's voice was soft, and Sister Zhao was obviously comforted by her words, forgetting the picture of being reprimanded by Manager Zhang just now, and her mood was better.

"What do you want to ask?"

"Is there any leftover of the recipe for today's noon menu in the site canteen, as well as the location and channel where all the ingredients were purchased?"

Sister Zhao replied one by one, "Today's noon recipe is stir-fried dried tea with celery, stir-fried pork slices with potatoes, scrambled eggs with leeks, cold salad with shepherd's cabbage, and the soup is radish and tofu soup, steamed white rice." ”

The recipe that Sister Zhao said is consistent with the recipe reflected by the workers.

"Celery, potatoes, leeks, dried tea, sliced meat, radish, tofu, all I bought at the nearby Murakami morning market, very fresh, definitely no problem, only a little celery has not been used up, the rest is made in the dish, and the finished dish is left, all in the rice bowl of the cabinet. ”

Yu Fei stepped forward to inspect and found a few pots of food left in the simple cupboard, took out the sampling box, and put some of them into the sampling bag and sealed them.

Yu Fei, Zhang Lin and Gao Meng were busy sampling on the spot, Lin Xiaoxiao asked Sister Zhao, listened carefully, and continued to ask, "What about the shepherd's cabbage? Where did the cold salad come from at noon? ”

Sister Zhao pointed to the pool outside the canteen, "I didn't buy the shepherd's cabbage, I dug it from the wild grass next to the construction site, I ate most of it at noon, and a small part was left by the pool, which had been picked and washed to prepare for the evening soup." ”

Li Bai was learning about the general situation of the canteen on the site with Manager Zhang, and Sister Zhao took the initiative to take Lin Xiaoxiao to check the remaining shepherd's cabbage.

A pot of washed shepherd's cabbage beside the pool was quietly placed there,

The leaves were still stained with water, and it looked like they had just been cleaned.

Lin Xiaoxiao recognized many kinds of wild plants, when she was in her hometown, every weekend, her parents would take her to the suburbs to play, her father was a high school biology teacher, taught her to recognize many wild plant species.
