Police Detective

The case now has three steps. The first step is to send the poisonous prawns to the laboratory in City A, Province B.

City A in Province B is a large city in the southwest and has a national key laboratory. City B is simply incomparable. It was delivered overnight, and the results may be available at noon tomorrow. In fact, many people are curious about this sample. The drug that can cause food poisoning symptoms is currently unknown.

Maffei has countless derivatives, and so does Ice. For example, one of the derivatives of ice is the very famous shaking head, which also causes huge problems.

Many people think that this thing cannot be described as addiction, which is very wrong. One characteristic of this small pill is that the lethal dose varies greatly. Some people are fine with just one gram, while others can die with just 0.01 gram. So definitely don’t try this. Not only will it cause permanent damage to the nervous system, the K powder that may be included in it will also cause urinary tract problems, which is very painful.

The second is to check the source. Several people have been summoned so far, all of whom are food workers, but no one knows about it. Moreover, after watching the video of the kitchen, no one was found to have poisoned the food.

Since the things that happened came from a batch of goods, the source of the poison should be the goods themselves.

The third natural step is to investigate the motive. Currently, there are two most likely motives. The first is what Bai Song and Liang Si said, that there are overseas organizations deliberately retaliating, and the second is that there was leakage during the entrainment and transit.

However, the continued investigation of the case did not support some of Bai Song's conjectures.

"The top priority is to do preventive work for all catering companies in this city, and make the work meticulous to everyone." Bai Song sighed: "Let's deal with the situation in this city first, and let's find a way."

"Work is already underway," Director Gao of City B said, "This kind of thing cannot allow a third poisoning accident to happen."

In fact, it is not just two restaurants that have discovered the problem at all, but seven have been discovered so far. In the remaining five restaurants, some customers had no reaction after eating, and some were stopped in time before their food could be served.

Mr. Qian was also called over. The batch of goods with the problem was not large. It was mainly concentrated in these seven restaurants, with almost 300 kilograms of goods. This batch of goods is a 2 kilogram box of imported shrimp. Now they have all been found. Moreover, not all of them are available. This substance has been detected in only more than 30 boxes.

"The concentration is different." Sun Jie looked at the simple laboratory report: "It can't be put in by the vegetable delivery workers or purchasers. No matter how stupid they are and no matter how much money they charge, they will not leave so much evidence. And It seems to me that a long time has been put into it, so it should have soaked in before the salt froze.”

"Some of them are unpacked and contain poison, which means the problem lies overseas. It may be that the customs inspection is not thorough enough," Bai Song said.

"Well, I am also inclined to this situation, but it is difficult to trace the origin. The boss named Qian should have no problem." Director Gao said: "He has no motive for doing this."

"It is unlikely that there is a local colleague who framed me." Bai Song said: "Let's wait for the results from the provincial capital tomorrow."

After reaching these conclusions, it was natural to let Qian Tai go.

Qian Tai has mixed emotions. He is happy that he does not have to bear huge responsibilities, but worried that he is so unlucky that few restaurants here will dare to use his products in the future.

But in general, he still understands that this is not a big problem. He can continue to operate the market in City B under a different name and let others come. Not only that, even if he lost all the market, it wouldn't be a big problem. It would be ten thousand times better than going to the detention center and spending some time on his own.

Qian Tai could understand how business could be so smooth. He was still very grateful to Bai Song. Because Bai Song and others were here, he quickly analyzed that this case had nothing to do with him, otherwise he might be summoned for 24 hours, in which case he would be completely embarrassed.

These goods came in from the port of Tianhua City. The source of the goods was Ecuador. From the source to the dining table, they did not pass through Southeast Asia. After traceability, the goods in the same container as these shrimps were also randomly inspected, and there were no problems.

This actually made Bai Song feel helpless.

Ecuador is a country in northwestern South America, half a world away from us.

The frozen large white shrimp we eat in China is scientifically called Litopenaeus vannamei. Most of it comes from here. It is much cheaper than domestic shrimp. Even if it is transported such a long distance, it is still high quality and low price.

In fact, the "XX prawns" that we eat every day, or the prawns used in restaurants, including those in cafeterias, are all this kind of shrimp, and they basically come from here.

After the case was reported, the place of production offered to conduct independent inspections and was very cooperative, but Bai Song knew that the case might end there.

The six people who were poisoned recovered fairly well. Sun Jie checked their physical conditions and found that they were basically fine, but Sun Jie always felt that their heartbeats were still a little slow.

This feeling may be Sun Jie's psychological effect, because everyone's body constitution is different, and a heart rate of over 60 is normal.

Just like that, the day passed.

As Bai Song expected, after Liang Si heard about the progress of the case, he put it on hold and held a summary meeting as usual.

The source of the three steps mentioned before has been found, the motive is unknown for the time being, and the ingredients have not yet been revealed, but for Si Liang, this kind of case is of little significance. If it was said that the group of people arrested last time were deliberately retaliating or someone was deliberately creating a large-scale mass case, Liang Si would be very concerned. Now it would be enough to hand over the food poisoning that appeared for unknown reasons to the local department.

Today is April 29th, and all participating teams have returned to District A of City B.

In the statistical scores, Tianhua City still ranked first in basic points. However, due to the large number of cases in the county where Tianhua is located, the score weighting is relatively low, and the final score ranked third, with more than 540 points.

The first place was won by a team from Zhejiang Province with more than 570 points.

Such results are naturally very gratifying. The scores generally exceeded last year's, but they still did not break the records of Bai Song and others.

At this moment, these have become unimportant things. Bai Song and others have no intention of holding this meeting all morning. They still want to know what this thing is. If they don't know, they feel a little itchy in their hearts.

This was also the first time Bai Song came into contact with a similar case. The place of origin was so far away that he was extremely unfamiliar with it.

Finally, at one o'clock in the afternoon, the laboratory in the provincial capital produced some physical and chemical analysis results.

This is similar to what everyone thinks, but completely different.

This is indeed a drug, but it is not a derivative of maffei or ice, but a derivative of coca!

Thanks for the reward of 12,000 coins, which is too expensive to change the name. Mr. Feng is really generous.
