Gao Fei: "The situation I have is similar to that of Zhou Lao, and now think about it, if it is ergot poisoning, then we must consider the cereal products that the patient has eaten." ”

Lu Li: "My flow data here shows that all patients have eaten bread, but the places where they buy bread are different. ”

Xiao Chu: "The staple foods that can be made from cereals are steamed buns, bread, and other flour-based snacks, although the places where you buy bread are different, maybe the bakery uses the same raw materials." ”

Wang Xiaoxiao: "It is not excluded that the raw materials used in the bakery are the same as the moldy rye used by Wang Yunhao's family, and I think we should focus on tracing the source of the raw materials of the rye bread in the bakery." ”

Gu Yanan didn't speak, but directly handed everyone an electronic map with blue dots, red dots and red circles on the map.

"Sister Yanan, what is this?" Wang Xiaoxiao asked.

"The blue dots represent the address of each patient, the red circles represent the patient's congregation area, and the red dots in the red circle are the bakery, and these red dots are the focus of the next flow survey."

Lu Li suddenly realized, "Yes, most people will choose a bakery close to their home to buy bread, and according to the place where the case lives, you can find the problem by looking for the surrounding bakery, and combined with our previous flow data, the source of poisoning this time will definitely be found." ”

Several members of the emergency response team contacted each county where the case was located, and conducted an investigation of each bakery overnight based on the previous investigation data and the map provided by Gu Yanan.

——

Day 2 at 8:30 a.m.

Lianhai Center for Disease Control and Prevention, Emergency Office.

The emergency response team received feedback from the counties and districts about the survey.

Several problem: The raw materials for rye purchased by the bakery are the same batch, supplied to a certain supplier.

After inquiring about Wang Yunhao, it was found that the pig feed rye he purchased was also from the same supplier.

The county sent both the raw rye raw materials and the finished rye bread sampled from the problem bakery to the lab.

The test results came back quickly and a large amount of ergot toxin was detected in this batch of rye.

Gu Yanan reported the results to Director Yang of the center, and Director Yang contacted several relevant departments to seal up the problematic rye, and the distributors of the problematic rye were controlled by the police, and the problematic bread products that had entered the market were also recovered.

In the evening, Gu Yanan wrote a summary report of the epidemic in the emergency office.

An agricultural product dealer imported a batch of problematic rye from abroad.

Rye contains a lot of ergot.

Because of quality problems, dealers sell rye to bakeries in counties and districts at low prices.

The purchasing power of the bakeries was limited, and the dealer thought of selling rye to pig farms as pig feed, so he found Wang Yunhao in Wangjia Village and sold thousands of catties of problematic rye at a price lower than 1/2 of the market price.

Wang Yunhao grinds the problematic rye into flour, mixes it in pig feed, and feeds it to the pigs on the farm.

Because Wang used to be a veterinarian, he used to experiment with more than a dozen pigs before changing to new feed.

Wang Yunhao's wife, Li Xiaoya, made black flour steamed buns from rye flour for her own family's consumption.

After eating the new rye feed, the pigs lost their appetite and died the next morning.

Wang Yunhao's family had symptoms of poisoning one after another, Wang Yunhao was the first to get sick, followed by Wang Erzhu, an employee of the pig farm, and Li Xiaoya also had symptoms of poisoning during the hospital escort.

Each bakery used the problematic rye to make rye bread and sold it to residents in the surrounding communities, who developed symptoms of ergot poisoning and were taken to the hospital.

After sampling and testing, ergot toxin was detected in the problematic rye, pigsty trough, and black flour steamed buns stored in Wang Yunhao's home.

Ergot toxin was also detected in the same batch of rye purchased from the bakery in question, as well as rye bread made from it.

After treatment, the patients were discharged one after another, and some critically ill patients were left with sequelae such as eye blindness and amputation.

After the seizure of the problematic rye and the recovery of the problematic bread, there were no new cases of poisoning, and the epidemic was brought under control.

After writing the summary report, Gu Yanan filed the report.

Xiao Chu watched Gu Yanan finish everything, and sighed on the side, "Two days ago, Sister Yanan and I ate bread when we worked overtime at noon, but fortunately I didn't buy rye bread, otherwise I would have been poisoned and hospitalized now." ”

Wang Xiaoxiao asked: "The place where you buy bread is a problem bakery." ”

"Yes, I was shocked when I found out the list of problem bakeries at that time, but when I looked closely at the types of problematic bread in the problem bakery, fortunately it was not within the scope of our purchase, so I was relieved."

Gu Yanan listened to the conversation between the two, as if he suddenly remembered something, hurriedly stood up, and walked back with his bag, "I have something to do, get off work first." ”

I just remembered that Nan Hanfei also has the habit of taking bread for breakfast, and he likes to eat rye bread.

On the way, Gu Yanan called Nan Hanfei, "Have you eaten rye bread recently?" ”

On the other end of the phone, Nan Hanfei was also on his way home from work, and was puzzled by Gu Yanan's anxious tone and sudden question, "I eat every morning, what's wrong?" ”

"Where do you buy bread? Is there anything uncomfortable in your body? ”

"The bread was bought by my aunt, I have always been in good health, and I am not uncomfortable, why do you ask that?"

"It's important to ask your nanny aunt which bakery she buys her bread from."

Although Nan Hanfei felt doubtful, he still did what Gu Yanan asked, and soon called Gu Yanan back, "I bought it in the cake shop downstairs in our community, is there any problem?" ”

Gu Yanan breathed a sigh of relief, that cake shop was not on the list of problem bakeries.

"Oh, it's okay now, I'll go back right away and we'll meet later."

Hurried back to Xinhua Apartment and found Nan Hanfei standing outside the door.

"Go to your house." Gu Yanan pointed to Nan Hanfei's apartment door.

Nan Hanfei did so, Gu Yanan went straight to the kitchen after entering, opened the refrigerator, took out all the rye bread inside, carefully checked the manufacturer and production date, and after making sure that there was no problem, he stuffed it back again.

Nan Hanfei watched Gu Yanan's every move, and waited for her to finish before he asked with a smile, "Yanan, are you so nervous?" Is it because of the recent rye problem bread incident circulating on the Internet? ”

"You know about this?" Gu Yanan asked in surprise, she thought that Nan Hanfei was busy investigating the case and would not pay attention to these news.

"I also saw the news on the Internet just now, this incident has caused a stir on the Internet, but there are official channels to explain, the incident has calmed down, and you have worked hard for disease control."

"My job." Gu Yanan smiled slightly, in the face of Nan Hanfei's praise, she was always like this.

"Stay for dinner in the evening?" Nan Hanfei invited.

"Yes, but I don't want to eat rye bread."

"There's fish in the fridge, I'll make you sweet and sour fish to eat."

"Okay, I feel like happiness came so suddenly." Gu Yanan rarely had a coquettish tone.

"Well, the mouth is one of happiness."

"Oh...... What about happiness two? ”

Nan Hanfei opened the refrigerator door, took out a fish with one hand, and gently tapped Gu Yanan's forehead beside him with the other, "Our time is so long, we will slowly experience it in the future." ”
