The outpatient department quickly reconciled the patients' medical records and concluded that the patients had the same symptoms, but it was not clear how they were infected.

In other words, they may have eaten something by mistake or touched something. ”

After listening to the doctor's words, Chen Hanyu immediately took an objection.

"I don't think so, it's impossible for so many people to eat the same thing, and if we touch it, we should be in the same situation as them if it spreads like this. As soon as Chen Hanyu finished speaking, a doctor fainted in the office of the outpatient department.

With the support of everyone, the doctor was temporarily placed in the outpatient bed, and Chen Hanyu found that his symptoms were the same as those of those patients, and Chen Hanyu did not ask the staff of the laboratory department to take samples until the doctor woke up.

"Doctor Pan, think about it, when did you start feeling unwell?" Chen Hanyu slowly controlled the flow rate of the infusion tube.

"I was probably just a little bit old in the morning, but I didn't eat anything. Dr. Pan was also confused, and he also wondered that he had fainted suddenly.

Chen Hanyu didn't speak, and the results of the laboratory department came out quickly, and pentanine muscle salt was detected in Dr. Pan's saliva.

When he heard the news just now, Chen Hanyu was obviously stunned, and then did not speak.

Pentanine is a kind of cellular tissue, but this tissue is usually parasitic on plankton and is extremely viable.

"Vice President Chen, have you heard of it?" The doctor in the laboratory department couldn't help but ask Chen Hanyu.

Chen Hanyu nodded and said, "At first, when this pentanine muscle salt was tested, it was in North Africa, and everyone in that place knew that the environment was not very good, and it was notoriously mixed. ”

Chen Hanyu told them that the first case of pentanine muscle salt was detected in China because of aquatic products, and international shipments will not test whether aquatic products containing such cells are toxic, and it is indeed non-toxic.

"Yes, pentaine muscle salt is colorless and non-toxic, why would they become like this?" Xu Feng pointed to the doctor in front of him and said, "It stands to reason that even if people use it when they come into contact, it will not cause lesions." ”

Chen Hanyu also thought about this question, and he never figured out what caused the abnormality of this pentanine muscle salt, thus invading various functions of the human body.

In fact, after thinking about it carefully, combined with the appraisal report of the laboratory department, Chen Hanyu locked his eyes on the doctor's diet and saliva test, and the verification was naturally saliva, and the things that entered from the mouth were nothing more than water, food, and nothing else.

"If this kind of thing is to eat and drink...... Chen Hanyu suddenly remembered something, and he hurriedly asked his colleagues in the laboratory department to find out whether this pentanine muscle salt was a lesion when it entered the oral cavity or a lesion that occurred after it completely entered the body.

"Vice Dean Chen, is this very important?" asked the director of the laboratory department, puzzled.

Chen Hanyu nodded heavily and said, "Very important!"

Seeing Chen Hanyu's expression, Xu Feng hurriedly asked everyone to cooperate with Chen Hanyu and make sure to figure things out.

Chen Hanyu meant to go to the homes of several patients to see what they were eating or drinking.

"Okay, I'll arrange it!"

"Don't be busy, look for it nearby, ask the families of those patients, who is willing to lead the way!" Chen Hanyu hurriedly called out to Xu Feng, he was too impulsive.

Chen Hanyu's proposal was quickly responded to by the patient's family, and a lady squeezed in front of Chen Hanyu and told him that several residents of their compound had the same symptoms and that it would be convenient to go to them to save time.

"Okay, let's go to the eldest mother!" Chen Hanyu said and beckoned Xu Feng to follow him into the car, and the group came to the compound where the eldest mother was with the equipment.

The compound is actually very clean inside and out, and the eldest lady also told Chen Hanyu a lot of things along the way, what they have eaten in the past two days and their usual daily routine, including drinking water and the like.

It's all very ordinary things, and Chen Hanyu doesn't see anything wrong.

"Auntie, have you eaten anything different in the past two days, it's just that you don't usually eat much!" Chen Hanyu said as he walked to the living room, and he instructed his colleagues in the laboratory department to do a test of all the vegetables and meat.

"I think about it, my family has eaten fish for the past two days, originally we didn't eat fish, do you think there is something wrong with this fish?" The eldest lady didn't wait for Chen Hanyu to respond, and hurriedly ran to the refrigerator to take out the fish, and there was still a very fresh half of the fish in it.

Chen Hanyu took out the fish, and he asked all his laboratory colleagues to give priority to inspecting the fish.

"By the way, Auntie, you also ate fish, didn't you?" Chen Hanyu was a little puzzled, everyone in the family was sick, but the eldest lady had no problem, this was obviously his own breakthrough point.

"Yes, I boiled two pots, because this fish has no thorns, I will half braised and half sliced directly and steam it and eat it!" The eldest lady said that this pointed to the dishes on the table, and he told Chen Hanyu that he had not had time to clean it up.

Chen Hanyu nodded, this time he didn't let them test first, but took out the silver needle in his arms, if there was a problem in this fish, the silver needle would definitely turn black.

There was no movement in the steamed fish, and Chen Hanyu pierced another silver needle into the braised fish.

After less than three seconds, the silver needle began to turn gray, and a gray papier-mâché-like substance condensed on his surface.

"The problem really appears here!" Chen Hanyu figured it out, according to reason, there was no problem with the meals made by normal seasonings, but there was only a problem with this fish and meat.

But how does this explain that the steamed ones are all high temperatures, why one is toxic and the other is not.

"It's been tested, it's been detected!" a colleague from the laboratory department shouted loudly, he looked at Chen Hanyu and said, "Vice President Chen, there is pentanine muscle salt in this fish. ”

"Okay, you first go and investigate where the fish of pentanine muscle salt is sold, and let the eldest lady lead the way. Chen Hanyu then motioned for Xu Feng to contact the people from the Department of Health and ask them to detain the person.

After doing this, he began to analyze why there were two different variations of the same fish, and it was made by the same person.

In order to screen out the concentrated problems, Chen Hanyu specially went to several other households in the courtyard.

They all put a plate of fish on the table, and there are many ways to cook it, but the ingredients will always be the same and different.
