There are two reasons why oysters are sent to the meeting. One reason is that the shells of oysters are so thin that they are easy to crack when they are hit during transportation. Another reason is that oysters will open when the seawater is salty, so the opening of oysters is not caused by deterioration. This kind of raw food is transported in the whole cold chain and generally does not deteriorate.

Will there be parasites in oysters?

There will be.

No matter what kind of meat, it will have parasites in its body, so there are parasites in oysters, but generally speaking, there are not many parasites in oysters, which will not affect the nutritional value and taste of oysters.

However, it should be noted that parasites will change the host, so when eating oysters, they need to be cooked before they can be killed, so as to avoid all kinds of discomfort caused by human infection with parasites after eating.

Can steaming oysters for 3 minutes kill parasites?

It depends.

Because parasites live in the meat of oysters, oysters must be cooked thoroughly in order to kill parasites completely. Oyster meat is tender and belongs to high-protein food, which is very easy to cook, but the shell is relatively heat-resistant.

Oysters can be cooked completely in about 3 minutes without shell, but 3 minutes with shell is not enough, and it takes at least 10 minutes to cook, so whether oysters can kill parasites in 3 minutes depends on the specific situation.
