To be honest, the speed of detection of real pathogens is really not fast.

It has not even been scientifically researched to collect samples, and to investigate the speed of pathogenic bacteria carrying ingredients.

But this is not incomprehensible. After all, the research is carried out in a targeted manner, and the hospital must give priority to the treatment of patients, and only then can the cause of the patient's poisoning be investigated in a targeted manner.

Moreover, the information given by Shuicang Criminal is not just the test results of patients in one or two hospitals after they were poisoned, but the answers obtained after the other party confirmed that all hospital patients' food poisoning came from the same germ.

Although the time will be slower, it is very useful.

And they not only determined that it was the same germ, but also that the germs carried by the patients all had the same genetic shape.

In other words, the source of infection is the same, and the source of food poisoning is the same for all people.

And this time the real body of the pathogen is Vibrio parahaemolyticus.

The incubation period of this germ is 8 to 24 hours, which coincides with the time when Happy Restaurant is open at night and the time between the patient's ingestion of the germ and the onset of the disease.

In other words, this confirmed that the Happy Restaurant was the culprit that caused the food poisoning of hundreds of people.

After all, most of the patients were rescued by the hospital, so you can naturally know this information by asking.

"The question now is what kind of food contains this bacteria."

Koshimizu Nanatsu watched Tang Ze hang up the phone, touched his chin and analyzed the information he heard from the speakerphone earlier:

"Science Research has investigated so many ingredients, but they have not found any ingredients that carry pathogenic bacteria. Now that we know that it is Vibrio parahaemolyticus, we should conduct targeted investigations."

"Vibrio parahaemolyticus is mainly a bacteria that grows in the sea, that is, fish and shellfish." After all, Tang Ze still has C-level biology, and he still knows some simple biological knowledge.

"But during the criminal investigation of Mizukura, I found that the dishes are also of various kinds, right?" Koshimizu Nanatsuki thought about it and said, "It seems that many patients did not eat fish and shellfish yesterday."

"I have some clues." Tang Ze narrowed his eyes and said, "If everything is as I thought, then maybe the case of food poisoning can be solved."

"Senior, do you already have a clue?" Koshisui Nanatsuki asked in surprise.

"There are some."

Tang Ze nodded and said, "Let's go, let's verify the cause of food poisoning first. Maybe after we know the truth, we can also solve the murder case."

"Okay, let's wait and see." Koshisui Nanatsu quickly reviewed the obtained information in his mind, but he had no idea of ​​a breakthrough, so he nodded in anticipation of Tang Ze's reasoning.

Taking Yueshui Nanatsuki all the way to the Happy Hour restaurant, Tang Ze entered the back kitchen of the restaurant again.

At this moment, the restaurant has been suspended, and only the store manager is standing here, which seems very deserted.

"Two criminals, what's the matter with you this time?"

When the young store manager saw the two criminals coming, he hurriedly asked, "Is the result of the investigation out? Does it have anything to do with our restaurant?"

"At present, we suspect that the special sauce in your store caused all this." Tang Ze walked to the back kitchen and found the vacuum-packed special sauce.

"The ingredients are milk, scallops, onions, meat extracts, vinegar, and celery." Nanatsuki Koshimi read out the ingredients.

"how is this possible!"

The store manager on the side said excitedly: "We use high-priced raw scallops, but they are delicious!

And we will pour the sauce into a glass container, allowing guests to freely take it according to their preferences.

And all the sauces are bottled before opening, and we have strict rules. The sauces delivered on the same day will be used up on the same day, and the freshness is absolutely guaranteed! "

"Then what if I can't use it up that day?" Tang Ze picked up a glass container and asked rhetorically.

Faced with Tang Ze's rhetorical question, the young store manager quickly explained: "When the business is over, it will all be emptied, and the containers should be cleaned.

As for the unopened ones, it is considered that the employee benefits are taken in turn. After all, the shelf life of this vacuum packaging is 7 days, and at most the taste is not as fresh as that day. "

"Sure enough, this is the reason why the research institute couldn't find pathogenic bacteria, because the samples they took were empty containers after washing."

Tang Ze heard the words with a clear expression, looked at the store manager and said, "You said that the sauce will be taken by the employees in turn?

Then please contact those shop assistants and ask them to provide yesterday's special sauce.

In addition, if any of them eat the sauce, let them go to the hospital immediately! "

"This..." Hearing Tang Ze's words, realizing that maybe there was a problem with their special sauce, the store manager couldn't help but lose his mind.

"Come on, do you want your colleagues to get food poisoning!" Under Tang Ze's urging, the store manager hurriedly picked up the phone and went to the contact person.

When the store manager finished contacting the clerks who took the special sauce yesterday, and asked the one closest to the store to come back with the sauce, the other party's face turned gloomy.

Obviously, this is also a huge blow to his owner. After all, this restaurant is so prosperous, and his salary as the owner is also very high.

"By the way, today's special sauce will also be checked." Tang Ze reminded, and motioned Yueshui Nanatsuki to take a bag of today's sauce and tell it to the people of Kesouyan later.

"But senior, are you so sure that the special sauce is a matter of carrying pathogenic bacteria?" Nanatsuki Yueshui asked involuntarily, "Aren't you afraid of judging it's an oolong?"

"That's better than a few more poisoned people."

Tang Ze smiled and said, "When dealing with uncertain dangers, I always plan for the worst.

Besides, I also have enough confidence in my reasoning. Taking a step back, even if my judgment is wrong, it is nothing but troublesome people's efforts.

Instead of watching them go to the hospital, I would rather be complained by them. "

"Would you rather be complained about?" Koshimizu Nanatsu murmured in a low voice, seeming to know more about Tang Ze.

Perhaps, this is the reason why the other party was able to prevent many cases. He upholds the code of conduct that is different from others.

With a little sigh, she asked the store manager where the special sauce was stored today, then turned and walked to the big box in the corner, ready to take it out for the staff of Scientific Research to take it away.

But when she opened the box, her eyes fell on the inside of the two sides of the fan blades that the box opened.

"Senior, look at this." Koshimizu Nantsuki called to Tang Ze, and his fingers scratched the white translucent rubber surface inside the fan blade of the box: "Is this gum?"

"That's right." Tang Ze walked over and nodded, "This should be a box specially used for refrigeration."

"Sure enough, there is an inseparable connection between the two." Yueshui Nanatsu raised the corner of his mouth: "Everything is connected."

At this point, everything is actually very clear, and all the clues form a clear vein.

After the samplers from Kesouyan came to collect evidence, the two asked the store manager another question, and they separated directly in the restaurant.

Of course, I didn't have any plans, but simply got off work.

Yes, although both cases are very urgent, the search also requires procedures and evidence.

To be able to investigate this step today is already the limit, and the rest needs evidence to speak.

In addition to identifying the special sauce, Tang Ze also contacted Takagi and others, and went to Lichen Machinery to seize the top soup processing machine that Ikedo Food Processing sent to repair.

The seizure was not because of the confirmation of the machine or the one that created the wound on the neck of the deceased, but to investigate the problem of the machine itself.

To this end, Takagi and the others also hired professionals to conduct inspections.

Everything that follows is fermenting, all Tang Ze can do is to wait for the evidence to settle before taking the next step.

And this case of food poisoning with hundreds of people finally made a breakthrough on the night of the incident, and also gave a preliminary account to the boiling people.

"According to the investigation of the scientific research, it was finally found that the ingredients carried by the pathogen were the special sauce of Happy Restaurant. The police are currently conducting the next step of investigation..."

"Happy Restaurant did not receive regular inspections by the health center, or was severely punished for this accident."

When Karizawa and Ayako were sitting at the dinner table at home eating their sweetheart's dinner, the evening news reported the subsequent events.

"Are you going to investigate this matter again today?" Ayako, who was beside him, was surprised when he heard Tang Ze's name appearing in the search details described by the announcer in the news report.

"Well, it has something to do with a murder case. The deceased was a salesman from Maruyama Food Wholesale Company, which was their designated food supplier." Tang Ze nodded.

"Then are they the ones who caused the food poisoning this time?" Ayako asked involuntarily.

"No, if my reasoning is correct, it should have nothing to do with Maruyama."

Tang Ze smiled and said, "Okay, it's off-duty time, let's talk about some light topics."

After the two had dinner, Ayako proposed to go shopping for daily necessities for a walk tonight.

Although Tang Ze was on the news today, he didn't show his face after all, and the two of them were not disturbed in any way. Just like ordinary couples, they bought some snacks and daily necessities.

But after returning home, Tang Ze felt that the walk today was not enough exercise, so he pulled Ayako to practice two rounds of yoga and challenged the difficult movements, and then fell asleep peacefully.

Early the next morning, Tang Ze took Yueshui Nanatsuki and a large group of people to Lichen Machinery.

Of course, he took Koshimizu Nanatsuki, and the people under him were brought by the Minikura criminal.

After all, they came early this morning to solve the case of food poisoning.

"Why do you want to seal us up!"

Looking at the criminals who put seals on each machine, Lichen Miura looked at Tang Ze like a red-eyed wolf, wishing to eat him raw.

"You know about the food poisoning incident at the Happy Hour restaurant yesterday."

Tang Ze said lightly: "Poisoned food is the sauce made by your machine, it is made by your signature machine."

"This is an identification certificate."

Miura directly spread out the documents in his hand, and looked at Lichen Miura coldly with undisguised disgust on his face: "We will take apart the soup processing machine you use to make the sauce and hand it over to the experts for identification. Later, it was found that the parts in the heater were partially missing."

"What!?" Lichen Miura was stunned on the spot after hearing the words of the Shuicang criminal, and reached out to grab the appraisal certificate in the hands of the Shuicang criminal: "This is impossible!"

"Nothing is impossible."

The water warehouse criminal snorted coldly: "It is also because of the defect of the heater parts that the heater did not reach the normal heating temperature."

"So, this is also the reason why the Ikedo Food Processing Plant felt that the taste was not right and sent the machine to be repaired."

Tang Ze said lightly: "And the heating and sterilization is uneven. After the regular inspection of the machine, you did not find any defects in the heater. This is the responsibility of your factory."

"You can't justify it if you want to pretend to be ignorant."

Koshimizu Nanatsu looked at Lichen Miura with disgust: "The machine was regularly repaired but a few days ago, the damage could not have been caused by a day or two. That is to say, you just moved the machine, but did not check it at all."

"We want to build a factory in Dali, so there are not enough technicians to check!" Lichen Miura explained repeatedly: "Our factory will soon become famous overseas..."

"That's not a reason."

Tang Ze interrupted him directly: "Because of your irresponsibility, the lives of hundreds of people have been threatened, and you are still thinking about making money!"

Lichen Miura's lips trembled and his expression collapsed: "I have to do the work on Neon's side by myself, and Idaily's side has constant problems every day..."

"I remember when I came to visit you before, you were very proud of your own machines, and what brought you these were the compliments from the guests, but now you are depriving the guests of their smiles!"

Yueshui Nanatsuki's words pierced Lichen Miura's heart like a sharp arrow, and he was finally taken away by the criminals brought by Mizukura criminals with a pale face.

"Thank you so much for this time." Shui Cang Xun bowed slightly and thanked: "If it weren't for you, we probably wouldn't have discovered the source of the pathogen, nor would we have known that the machine was faulty. "

"fine."

Tang Ze shook his head and said, "We are here to investigate homicides, and everyone cooperates with each other to share information and benefit each other.

Now that the problem has been resolved here, let's say goodbye. "

"We still need to seal up the factory, and we need to wait for a while. The two of you will do it yourself." Shui Cang Xun looked at the two and smiled and said, "If you need anything in the future, please contact me as soon as possible."

"Well." Tang Ze nodded and bid farewell to the other party.

"This case is finally half solved."

Walking out of Lichen Manufacturing, Yueshui Nanatsuki stretched his waist: "But I really didn't expect, senior, that your breakthrough point is such a small change in the taste of food."

"If you say that, I know that I don't know how to cook."

His teasing attracted the eyes of Koshimizu Nanatsuki, and Tang Ze explained with a smile: "Although I am suspected of boasting, my cooking skills are very good, so when I heard President Ikedo say that the taste has changed, I noticed the problem. is there.

Learning is everywhere in life. To be a good criminal, you have to learn a lot. "
