Shen Anjun took a general look and temporarily eliminated all the rice.

The fixed purchase is only eggs, taro, and tofu.

Shen Anjun thought about these kinds, and it seemed that even if the tofu was injected and poisoned, it was not easy.

Generally, tofu is cooked together.

Unless all the tofu is poisoned, it can be guaranteed that a person can eat enough to be poisoned.

And the big pot dish in this canteen is impossible to serve to anyone, just enough to serve a piece of tofu to one person.

If it's in tofu, all the tofu has to be problematic.

The poisoned people are definitely not the 22 now, at least it has to be multiplied several times.

This is temporarily excluded.

Taro and grain have similar meanings.

It can be used as a staple food for cooking, and this practice varies.

Shen Anjun took a look, and the number of fixed purchases of taro was relatively small each time.

Because it is the season of taro production, although there are many taro purchases in the canteen, because of the good storage, the amount of each purchase is relatively large.

I bought it once or twice a month. It's basically all about storage.

Shen Anjun thought for a while, this seems to be eligible for poisoning.

The number of purchases is small, and the storage volume is large.

If the other party is poisoned randomly, they may poison more taro, and it is not easy to be detected.

When cooking, the poisonous taro may be eaten separately by everyone, and the less it is absorbed by the individual, it is not easy to be poisoned.

And if the canteen is used as food that day, the taro is steamed and supplied, and the unlucky ones eat one or two or more directly, it is easy to be poisoned.

Shen Anjun told everyone what he thought.

They also feel that it makes sense.

Could it be that this poison is really in the taro?

Zhang Yuan hurriedly asked people to check the time of the few meals that had taro as the staple food a few days ago.

Let's see if the time of onset of the disease can match the onset of the poisoning.

The result is really similar, not much different.

Except for two patients who were served taro at noon, they only became ill in the evening, but basically all of them were within the same day's time.

It seems that the problem of this taro is very big now.

Commander Zhang Yuan, regardless of whether this taro can be confirmed or not, it will indeed be the source of the virus.

But it is also necessary to find someone to seal it up and conduct the next step of testing.

There is also one thing that is fixed to buy, eggs.

Shen Anjun hadn't figured out any way to poison the eggs, and the others also felt that the possibility of eggs was not high.

After all, think about the shell of a raw egg that is actually quite brittle.

Even if you inject it with a needle, it is easy to break the shell or leave a mark.

Not to mention whether the shape of the egg in the injection play venom will change, people will find out.

Even this technology is difficult to implement.

In order to confirm everyone's idea, Shen Anjun and the others deliberately found ten eggs, found the thinnest syringe, and then added ten people, including Shen Anyun, to beat liquid into the eggs.

Even if Shen Anyun's kung fu is the best, at the very beginning of the needle, there will still be a particularly small pinhole left on the outside of the eggshell.

The weather in southern Sichuan is hot, and such broken eggs may stink the next day.

Very few eggs are purchased on the same day.

I asked the soldier in charge of the kitchen, and there was only one time a month, because the stored eggs were gone, and they were bought and used once, and the others were used at least every other day.

As for the rotten eggs, the cooks said they didn't find them.

For the time being, the suspicion of eggs can also be ruled out.
