"Xiaoxiao, what do you have requirements for your other half?height, weight, appearance, education, age, family background, background...... As long as you have any requirements, tell Sister Zhao, and Sister Zhao will definitely help you find the right one. Sister Zhao chattered, and had already taken out a small notebook, ready to start recording Lin Xiaoxiao's request.

"Thank you, Sister Zhao, but I already have a boyfriend. ”

Sister Zhao was stunned.

Everyone in the emergency office was stunned, and Li Bai's hand on the keyboard suddenly stopped.

"What? Xiaoxiao, do you have a boyfriend?

From Lin Xiaoxiao's graduation to the present, she has been working with everyone in the emergency team for more than a month, and I have never heard her say that she has a boyfriend.

Lin Xiaoxiao thought of the angel Xiaobai in the network, they did start chatting online when they were in college, and the angel Xiaobai sent her love letters in the last year.

"Well, I talked about it in college. Lin Xiaoxiao responded with a smile.

"Do you really have a boyfriend? But I've never seen him pick you up from work, I haven't seen you go on a date, I've never even seen him call you. Yu Fei asked.

"We usually contact at night, so none of you have met. Lin Xiaoxiao explained.

She was telling the truth, she usually chatted with Angel Xiaobai online at night before going to bed.

Yu Fei looked at Li Bai sympathetically.

Li Bai's face was gloomy.

Sister Zhao was a little disappointed, such a good girl already had a boyfriend, and sure enough, the good girl was targeted in college.

The desk desk phone rings.

Li Bai picked up the phone and frowned, which is a typical look when receiving the epidemic report.

Hung up the phone, Li Bai announced.

"There is a suspected collective food poisoning incident in the suburb of Daxi Village, and 11 people are currently being hospitalized, one of whom died. The People's Hospital is sending people to our laboratory to send patient specimens, and our emergency response team is now divided into two groups, Yu Fei and Gao Meng in a group, to go to the People's Hospital to conduct a flow of patients, and Zhang Lin, Yang Le, Lin Xiaoxiao and I in a group to go to Daxi Village. ”

——

Suburb, Daxi Village.

The CDC's on-site flow shunting stopped at the entrance of the village.

Four people carried the sampling box and walked to the patient's home.

At the same time, Yu Fei and Gao Meng's group had already started a flow of patients in the First People's Hospital, and the patient information they sorted out was immediately transmitted to Li Bai through his mobile phone.

The information contained the detailed addresses of the food poisoning patients, and Li Bai began to conduct door-to-door investigations based on these addresses.

However, most of these patients were hospitalized with their families, and the doors of their homes were locked at this time, and they needed to be led by village cadres to conduct household investigations.

From the information of the hospital, it is inferred that most patients become ill about half an hour after lunch, and there is a possibility of biological or chemical poisoning.

Chemical poisoning is likely to be caused by metal poisons, such as barium or potassium.

The fact that these patients had eaten or been exposed to the same food prior to the onset of illness was key to this outbreak.

Li Bai's group is looking for village cadres from Daxi Village to assist in the investigation, and Yu Fei has already obtained key information.

I learned from the inpatients that they had eaten steamed buns sent by Kim Dagang's mother at noon.

At that time, the steamed buns were still steaming, and they should have just been steamed.

Yu Fei immediately fed back the news to Li Bai.

Since there is a problem with the steamed bread, the raw materials used to make the steamed bread need to be investigated.

The village cadres took Li Bai and his entourage to Jin Dagang's house.

On the way, the village cadres chattered about Jin Dagang's family.

Dagang's family usually consists of three people, he lives with his daughter-in-law and his old mother, and his son goes to college in other places and comes back once or twice a year.

Their families are very good, the neighborhood relationship is also good, Da Gang wants to open a steamed bun shop in the village, in addition to the villagers of the village, there are also workers from nearby construction sites sometimes come to the village to buy things, if the steamed bun shop is really open, the flow of customers should be a lot.

Yesterday, a courier came to their house to deliver the dough machine, and that night their family had more noodles and distributed the dough to a few neighbors.

At noon on the second day, Jin's mother distributed the steamed steamed buns to several other neighbors. ”

"Wait!"

Li Bai noticed the same, just now Yu Fei came to the news that the patients in the hospital had eaten the steamed buns sent by Jin's mother at noon before they became ill, but the village cadres said that the Jin family had distributed the dough to the neighbors the evening before.

"Did Jin Dagang share the dough among the neighbors?" asked Li Bai.

"Yes, I was also given a piece of dough at that time, and I used it to make steamed buns that night, and I didn't feel any problems after eating it, and the noodles were quite fragrant. ”

Through the words of the village cadres and the poisoning of the Jin family, Li Bai felt that the possibility of the Jin family's poisoning could be ruled out.

The raw dough is non-toxic, and the steamed steamed bread is poisonous, which must be a problem with the Jin family's step in making the finished steamed bread.

Li Bai called Yu Fei, "Focus on asking the Jin family about steaming steamed buns this morning." ”

Yu Fei quickly called back.

"Figure it out, this morning steamed steamed buns are Mrs. Jin, she took out the leftover dough from last night from the refrigerator in the morning, felt that the noodles were a little wet, so she took out a bowl of flour from the porcelain bowl in the kitchen at home and kneaded it in, re-made the dough, made steamed buns and distributed them to the neighbors, and the family also ate a steamed bun at noon, and began to get sick one after another after eating. ”

At Jin Dagang's house, the flow investigation team focused on inspecting the kitchen, especially the raw materials that Mrs. Jin came into contact with in the process of making steamed buns.

The steamed steamed buns in the morning were still in the pot, and there were still a few left on the dining table, so I collected the remaining steamed buns, and went to the kitchen to knead the dough and found the enamel bowl that was still on the kitchen stove.

There is white powder in the bowl.

Li Bai wore gloves, pinched out a little powder with three fingers, and rubbed it.

"This is the flour that Mrs. Jin used when kneading dough?" Lin Xiaoxiao stood aside and stared at Li Bai's movements, and asked curiously.

"You can try the feel of these powders with gloves on. ”

Lin Xiaoxiao looked like Li Bai, wearing gloves, pinched out a pinch of powder from the bowl, rubbed it gently, and found that the powder felt astringent and granular.

"It's not flour! The flour is smooth, but the powder is kneaded like fine sand, which is supposed to be the crystallization of some compound. Lin Xiaoxiao said excitedly.

If you knead something that is not flour into the dough as flour, the steamed buns will make people poisoned, so the contents of the enamel bowl should be the source of poisoning.

"Take the whole enamel bowl and the contents back to the lab. ”

Li Bai gave an order, and Lin Xiaoxiao took out a large sampling bag from the sampling box, sealed the enamel bowl with the powder inside, and put it into the sampling box.

After coming out of Jin Dagang's house, the team went to the homes of other patients under the leadership of village cadres, focusing on collecting steamed buns that Jin Dagang gave to their neighbors.
