The aftermath of Tianjin's new crown positive for ice cream was not resolved, and Ukrainian imported whey powder used for the production of ice cream was tested positive again
.
Now both the government supervision department and the enterprise may be very nervous: a cold chain food has already made a lot of noise, and now it is necessary to also carry on imported food at room temperature? You may be more concerned, can you still eat ice cream and ice cream? Who knows if imported raw materials have been used?

1.
New crown positive ≠ live virus

The nucleic acid detection method of the new coronavirus is based on its RNA.
It can be detected whether the virus is dead or alive, even if the virus is dead without a whole body
.
For cold-chain foods, because the new crown virus survives for a long time at low temperatures, it is barely justified to treat "new crown positive" as a "live virus" to prevent it
.
In Qingdao, live viruses were indeed found in cold chain foods
.

However, it seems a bit of a dead end to treat the positive nucleic acid of normal temperature food as a live virus to prevent it
.
Especially imported normal temperature foods (such as whey powder) stay in the logistics and storage links for a long time, and the time and probability of virus survival in the environment of the cold chain are greatly reduced
.
(The weather temperature is a variable)

The raw materials of whey powder involved in this "ice cream positive" incident must undergo thermal processing during the production process, and the new coronavirus cannot survive
.
The production process of ice cream and ice cream is to heat and sterilize all the ingredients after mixing.
Therefore, as long as it is confirmed that there are no virus carriers in the factory, the new crown virus in the ice cream will not be alive
.

You ask me if I can eat it? All I can say is, if you can show me the sample, I would really dare to eat it
.
But you can't get it, and official experts don't dare to say that
.

2.
Live virus ≠ infectivity

Assuming that there is a live virus in the ice cream, will it infect people? In fact, even if there is a new coronavirus, it does not necessarily infect people
.
It's just that the greater the number of live viruses, the greater the probability of infection
.
The detection method of the new coronavirus is very sensitive.
In theory, only one virus particle can be detected
.

According to Wu Zunyou, chief expert of China's CDC epidemiology, the current cold chain products with positive new crown "CT value is relatively large, indicating that the virus pollution is relatively light
.
" Therefore, the infections that you see caused by the cold chain are basically employees in cold storages, warehouses, and docks.
They "usually walk by the river" and the probability of infection is higher
.
It is really not easy for ordinary consumers to infect the new crown from cold chain products
.

3.
Respiratory tract ≠ digestive tract

The new crown virus is a respiratory virus, and it is prevented from coming and going.
In fact, it is still preventing droplets and contact infection
.
With so many epidemics spreading, only a few cases are suspected to be caused by human-to-human transmission, and the expansion of the epidemic is without exception a human problem, it is a mobile person, a gathering of people
.

So far, no patient has been infected through diet
.
The new coronavirus cannot survive after entering the digestive tract, after all, the stomach acid environment is unbearable
.
Therefore, there is not enough evidence to support the expansion of nucleic acid testing to all imported foods, not to mention their downstream processed products
.

Even for imported cold-chain foods, testing the outer packaging is just "doing your best and knowing the fate", because you can never rule out the possibility of "negative outer packaging and positive internal"
.
But it is impossible for you to disassemble all imported cold chain foods
.

I have seen some people say "Importing is too harmful, so I just stopped.
" In fact, this is very irrational
.
Is the "double loop" that has been said so many times in the news for nothing? For commodities with very small imports, or with "spare tires", it is really irrelevant to stop them, but you can't stop for bulk commodities
.

For example, whey powder is mainly a by-product of cheese production, which is almost non-existent in China, and the demand is very large, so it is currently regarded as "just demand"
.
All kinds of frozen meat and aquatic products are also similar.
It is difficult to be fully self-sufficient in the country, and it is not conducive to stable prices and enrich market categories
.

Although the outer packaging of imported cold-chain foods is found to be positive from time to time, in general, consumers can still purchase and consume normally through formal channels
.
At most, pay attention to operational hygiene, wash your hands frequently, and don't touch your mouth and nose
.
Cold chain food is the case, and other imported goods are not a problem
