not very safe.

reason 1: coronavirus is very sensitive to heat. It is difficult to survive at higher temperatures. The temperature of the food we eat is relatively high in most cases. Even if the food producers pollute the food a little during the production process, it is difficult for the virus to remain active in this case.

Reason 2: Coronavirus needs a certain amount to cause disease. If the number of invading viruses is too small, it will be directly destroyed in the immune system. Even if there are sporadic viruses on the surface of the packaging box and food, it is difficult for us to reach the minimum amount of infection and cause disease when we eat takeaway.

The main route of transmission in novel coronavirus is droplet transmission. If people who make food are infected and there are no protective measures in the process of making food, it is easy to spread the virus into food. If the takeaway is infected, it is also very likely that the virus will be left on the packaging bag.
