It is not safe, because workers in a factory are already infecting each other, so even if they sneeze or cough, they may retain the virus on an assembly line.

These viruses may not be eliminated within a short period of time, and they can easily enter food at this time. If stored at a lower temperature, the virus is likely to survive longer. These live viruses will still be present in the sandwich when it reaches the consumer, making it easier to cause further infection to a greater extent.

In particular, sandwiches are deli foods that can be eaten right out of the bag and do not require further heating. If the virus remains in it at this time, the chance of infection is very high.

So the UK may not have done enough in this regard. It was not until more than 300 people were diagnosed positive that it began to discover the virus. This is a very fatal problem. Someone may have been infected before, but no one in the entire workshop knew about it.

And those sandwiches that have been produced long ago are still sold to every household. Now that the epidemic is so serious, how serious will be the consequences of the sandwiches sold before? , no one knows.

In areas where the epidemic is more serious, a kind of safety awareness should be formed. First of all, various disinfections are essential. This is especially true for the industrial chain that produces food. All personnel must wear protective clothing and masks tightly, so that no possibility of infection can be left on the food.

Before food is shipped out of the warehouse, it should be disinfected in a centralized manner. Ultraviolet light or ozone can be used for disinfection, and it should be fully sterilized and sterilized before being shipped out. After leaving the warehouse, a dedicated person should be responsible for it, and the food should be disinfected. Check their physical condition regularly.

A small oversight in food may cause much greater harm than in other industries, so we must not be careless in this regard.
