Oysters contain many important nutrients such as selenium, zinc, iron, Vitamin B12 and Vitamin D. The US Centers for Disease Control and Prevention (CDC) warns that eating raw oysters can cause vibrio infection.

Vibrio bacteria are a type of bacteria that live in coastal areas and often accumulate in oysters. There are many different types of vibrio bacteria, most of which only cause nausea or diarrhea, according to the Australian news site The Conversation .

However, there is a type of vibrio bacteria called vibrio vulnificus that causes serious health effects such as blisters on the skin, blood infections, and even amputation.

It is impossible to distinguish healthy oysters from oysters infected with vibrio bacteria with the naked eye. Infected oysters will still be fresh and taste similar to healthy oysters.

However, vibrio bacteria, including vibrio vulnificus, are very sensitive to high temperatures. Therefore, cooking oysters can completely kill this bacteria.

Recently, some countries such as the United States have used various methods to reduce vibrio bacteria in oysters. This helps to retain the taste and preference of eating raw oysters. These methods include freezing, low temperature pasteurization, irradiation or high pressure processing of oysters.

However, according to the US CDC, the safest way to cook oysters is to cook them properly. When cooking, make sure the oyster meat inside the shell is at least 63 degrees Celsius and maintained for at least 15 seconds. This will help completely destroy the vibrio bacteria in the oyster.

This means that if you are cooking oysters in the shell, you should steam them for 4 to 9 minutes, and if you are boiling them in water, you should cook them for 3 to 5 minutes, according to The Conversation .
