On the other side, the wife of the deceased, who was making a record with the police, cried, "My husband and I usually resell seafood, and early in the morning we go to the seaside wharf to buy some cheap seafood and sell it near the Daqing Road farmers' market to make a difference.

After coming back from the stall this morning, he said that he was dizzy and nauseous, maybe he had a bad stomach, and asked me to go to the pharmacy to buy him some medicine for diarrhea.

I was hit by a battery car when I went out to buy medicine, my leg bled a lot at that time, I was sent to the hospital, I treated the wound in the hospital, it took a while, and I went to the traffic police to deal with the car accident, and it took a while, and when I came back after buying medicine, I found my husband lying in the yard, I called 120 ambulance, and after the people came, they said that there was no help, so I called 110 again, and you came. ”

Since it is poisoning, it may be that the deceased accidentally ate poison, or it may be that someone else poisoned it.

Captain Liang Han asked the deceased's wife, "What did you eat in the morning?"

"I cooked porridge at home, and I bought meat buns again, and my husband likes to eat seafood, and he cooked some of the leftover seafood in the morning and ate it. ”

Just as he was about to go to the kitchen to check, the police guarding outside the cordon ran over to report, "Team Liang, people from the CDC are here, and they said they are here to investigate an outbreak of selling wild horseshoe crabs that led to the poisoning of many people." ”

"After?what?" Team Liang didn't react for a while, questioning.

"It is horseshoe crab poisoning, a marine arthropod, an ancient species, which has the custom of eating horseshoe crabs among the citizens of Yunhai, and often causes poisoning. Fu Bo explained in the ear of Team Liang.

"Oh, food poisoning, then the CDC should take care of it, let people in. ”

A tall young man, dressed in a white lab coat, carried a sampling box from the scene, and then followed four or five young people in the same costume into the scene.

"Yo, Director Li, meet again. Team Liang smiled and stepped forward to say hello.

The Liang team of the police station has a good impression of Li Bai, director of the emergency office of the Municipal Center for Disease Control and Prevention, and the two have worked together in previous cases.

Li Bai nodded in response, and explained his intention straight to the point, "Team Liang, our city CDC has received a report of the epidemic that there have been many cases of horseshoe crab poisoning among residents in the community near the Daqing Road Farmers' Market, and we have found the traders who sell wild horseshoe crabs here according to the clues." ”

"You are looking for Wang Er, he is dead, but his wife is fine. ”

Team Liang pointed to the deceased Wang Er on the ground, and then to Wang Er's wife who was making notes with the police next to him.

"You have to do an epidemiological investigation, that is, an epidemiological investigation, and ask Wang's second wife if you have any questions, she can provide a lot of clues. "Team Liang was eager to help.

Li Bai assigned tasks to the members of the disease control emergency response team, "Yu Fei, you question the family of the deceased;

Gao Meng, you sample the dead;

Zhang Lin, sampling the external environment;

Yang Le went to the kitchen with me. ”

There are a total of 5 members of the emergency team, Li Bai is the team leader and the director of the emergency office, and the remaining 4 team members are all young people in their 20s, and they are all boys.

In the kitchen, forensic doctor Fu Bo was looking at the uneaten horseshoe crabs in the pot.

"The horseshoe crab is very similar to the non-poisonous Chinese horseshoe crab, but there are subtle differences in appearance, there are barbs here, and they are on the small side. Li Bai said.

"Yes, Wang Er ate three round-tailed horseshoe crabs in the morning, and the rest of the carapace is here. "Fu Bo was very observant.

"CDC wants to bring some specimens back, do you police also want to keep specimens?" Li Bai asked.

According to past practice, when there is an epidemic and there are deceased, the police and CDC will collect specimens for testing separately, and sometimes the results will be shared, but most of the results are provided to the police.

"Of course, the police laboratory can test for tetrodotoxin. ”

"In addition to tetrodotoxin, the CDC can also test for several hydrophilic shellfish toxins. ”

"Okay, old rules, results are shared. ”

"No problem, as long as it complies with the process, we are willing to provide the greatest help. ”

Li Bai and Fu Bo have met twice, and both were at the scene of the crime, and they also contacted by phone several times after that, all of them exchanged test results, and this was the third time they met, and they were at the scene of the crime.

The contact at work made the two very tacit.

Fu Bo: "Do you have anything else to investigate? Our police on-site investigation is basically over, and we are ready to take the body away." ”

Li Bai: "We also have to find the whereabouts of the round-tailed horseshoe crab according to the clues provided by the deceased's wife to prevent more people from being poisoned." ”

After Team Liang finished dealing with the affairs of the yard, he also came to the kitchen, "Director Li, I sometimes think that your disease control is similar to the nature of our police work, and it is also like a detective, except that we track criminals, and you chase bacteria, viruses, and poisons. The first two times we dealt with bacteria were bacteria, viruses and organic poisons this time. ”

Fu Bo added, "Team Liang, their disease control people have another name - virus catcher!"

"Virus catchers, tall and tall, much better than us traditional police officers. ”

For compliments, Li Bai has always been calm.

"Team Liang, Forensic Doctor Fu, our CDC left first, and there are still many stalls to check in the Daqing Road Farmers' Market next door. ”

——

Daqing Road Farmers' Market, aquatic product trading area.

The Municipal Disease Control Emergency Team, the on-site staff of Lianyun District Disease Control and Prevention, and the food and drug administration department inspected together.

All the stalls were checked and no merchants selling horseshoe crabs were found.

The members of the emergency response team are spreading the knowledge of the epidemic while circulating every time, this time it is horseshoe crab poisoning, and the most talked about is of course horseshoe crab, which is also commonly known as horseshoe crab, saying that it contains tetrodotoxin in its body and cannot be eaten.

Some merchants questioned, "In the past, there were also horseshoe crabs sold in this aquatic product trading area, and people often bought them, and I haven't heard of eating poisoning." ”

"There are many kinds of horseshoe crabs, one of which is the round-tailed horseshoe crab, people will be poisoned after eating, and they will die in serious cases, the public used to eat the Chinese horseshoe crab, but now the horseshoe crab is listed as a protected animal in our Yunhai City, no matter which one is eaten is a crime. ”

Popularize scientific knowledge and popularize the law.

Coming out of the Daqing Road Farmers' Market, Yu Fei of the emergency team first sent the collected specimens to the CDC laboratory. Others continue to trace the whereabouts of the wild horseshoe crabs sold and conduct surveys of buyers.

——

Municipal Disease Control Laboratory, Sampling Office.

Yu Fei was carrying two large boxes full of samples and was filling out the sample receipt form.

The person in charge of collecting the samples is a 40-year-old eldest sister, a veteran employee of the CDC - Zhang Na.

She has always liked to make fun of young people, especially a group of young men in their 20s in the emergency office, and this time was no exception.

"Yu Fei, what about the rest of your singles group?"

"Hospitals and patients' homes do flow surveys...... No, Sister Zhang, why do you call us singles again? Although several people in our emergency office are young and don't have girlfriends, we are also single aristocrats. ”
