Oysters, also known as "oysters", are delicious, as can be seen from the description in the classic article "My Uncle Yule". Some people even say that eating oysters raw (that is, "oysters") is a peerless delicacy that exists in the sky but not underground. However, the US Food and Drug Administration (FDA) recently issued a warning in official website to remind people not to eat oysters raw. Because this seafood may also be infected with the recently popular Norwalk virus.

So, will oysters leave our table? Don't worry, because oysters do not contain this virus after cooking and cooking, both healthy people and people with low immunity can safely eat at this time. The FDA also reminds people that all seafood should be cooked as much as possible, which can greatly reduce the risk of infection with bacteria and viruses.

Since eating oysters raw is risky, how can cooked oysters be healthier and more delicious? When buying, how can I choose the best oysters? The following suggestions can help you make a delicious and healthy seafood meal:

1. When buying oysters, buy oysters with completely closed shells instead of oysters with open shells;

2. If you choose to cook, the shell of the oyster should be cooked thoroughly, and it is best to cook for 3-5 minutes after opening the shell;

3. If you want to steam, wait until the water is completely boiled before adding the oysters, and steam for 4-9 minutes after the shell is completely opened;

4. At the same time, it should be noted that in the process of cooking oysters, try to use small pots to avoid using too large pots to cook too much at a time, otherwise it may cause the oysters to be unevenly heated, so that some oysters cannot be cooked;

In addition, don't eat oysters that can't be opened when cooking.
