Meat factory infected with epidemic disease, frozen food with virus Can the mystery of the new crown be solved?

 Meat factory infected with epidemic disease, frozen food with virus Can the mystery of the new crown be solved?

According to the latest environmental sampling results of the new market released by Beijing disease control department, there are more positive samples in the comprehensive trading hall, especially in the partial sales areas of aquatic products and bean products, which cause serious environmental pollution.

Another noteworthy news: one week after the case occurred in Beijing, there was a separate new local case in Tianjin. The patient had no travel history in Beijing, and had been engaged in dishwashing since May 30, occasionally cleaning frozen seafood ingredients.

Almost at the same time, overseas seafood industry and meat processing plants also exposed a number of cases of collective infection of new coronavirus.

Recently, a large number of workers in many seafood factories in the United States have been infected with the new coronavirus: three seafood workers in Bristol Bay, Alaska, have been tested positive for the new coronavirus; a seafood company in Oregon has also been infected, and more than 120 employees have been tested positive for the virus.

In South Korea, novel coronavirus pneumonia has been diagnosed in many of the Department of Marine Fisheries in shonchung, and the route of infection is not yet clear.

In addition, in the near future, there are also joint meat factories.

Coincidentally, when the outbreak broke out in Wuhan at the end of last year, a large number of confirmed cases also appeared in the seafood market in South China.

At present, it is generally believed that fish are almost impossible to become intermediate hosts of new coronavirus in nature. What is the cause of the epidemic and seafood, meat has a inextricable link?

And the survey data also shows that the people infected in the new market are relatively concentrated in the aquatic products counter of beef and mutton hall. .

Seafood market or just virus distribution center

The analysis of the environment of these outbreaks is almost inseparable from the same link - cold chain transportation.

Low temperature is exactly the environment that new coronavirus likes.

In China, - 18 u2103 is the national standard recommended for frozen logistics, and also the recommended storage temperature for frozen food and frozen drinks. Some experts believe that the virus is not afraid of cold, which explains why the virus has been found several times in the seafood market with more refrigerated food.

The gene sequence of the new coronavirus in Beijing has been uploaded and shared, which shows that it is closely related to the new coronavirus strain in Europe, who officials said Tuesday. At present, there are different virus strains spreading, which does not mean that the disease is from Europe, but it is likely that the virus was imported from outside Beijing.

On the other hand, the epidemic in the farmers market and meat processing factory has a close relationship with its own working environment.

American meat processing plants and some food factories have become hotbeds of the virus. This is because the flow process makes it impossible for workers to maintain social distance. In order to ensure the normal processing ability during the epidemic, workers can only work with diseases. Zhu Yi, associate professor of the school of food science, China Agricultural University, analyzed in an interview with

She stressed that the outbreak started from the food market, suggesting that the biggest risk is the food industry practitioners in the food processing sector. Capture, storage and transportation, trade, slaughter, dissection, cooking and other links before the entrance are the risks.

Similarly, the merchants working in the farmers market are faced with similar problems: the staff touch the contaminated products by hand, rub their nose and eyes, they will be infected, and the dense flow of people in the market accelerates the spread of the epidemic.

This gives us a very important hint: is it possible that the source of transmission is an infected person or contaminated food, and the environment of the seafood market has created opportunities for rapid transmission.

In this way, places like seafood market may only be a huge transfer hub for viruses.

The mystery of the new crown is still puzzling

Although the outbreak in Beijing has made people nervous again, to some extent, it has also made people more aware of the virus.

In view of the epidemic situation in Xinfadi, scientists have recently analyzed a variety of possible transmission paths: the virus lurks in the imported frozen food, because it has not evolved; the virus lurks in the dark and humid environment such as the wholesale market of agricultural products in Xinfadi, which has not been disinfected or sterilized, and suddenly exposed to infect people within a certain period of time, resulting in slow evolution, etc Wait.

The path of virus transmission is a rigorous and complex scientific process, which cannot be concluded. However, the new development has been reminding people that even though the path of the virus is still uncertain, the prevention and control network must be equipped with all-around strategies.

After the outbreak of the new market in Beijing, the agricultural products market has almost overnight become a new target for epidemic prevention and control all over the country. Large scale investigation has been carried out rapidly, nucleic acid testing has been carried out for market practitioners, and sampling and screening has been carried out for the market environment.

In addition, since June 17, Chinese customs has suspended the export of products from a German pork slaughtering and its segmentation and refrigeration enterprises to China.

For individuals, although there is no evidence of infection through eating food (including seafood products), the CDC has suggested that in order to reduce the possible risk, people should not touch raw fish and meat when buying food.

The concealment and tenacity of the new coronavirus are beyond peoples cognition. For human beings, to know new crown may be doomed to be a journey against the wind. (end)
