In addition to many parasites, oysters also contain norovirus and Vibrio cholerae. Norovirus may cause gastroenteritis. Vibrio cholerae can cause high fever, septic shock, skin ulcerating blisters and even fatal septicemia. Therefore, eating raw oysters is very harmful, so we should try to avoid eating raw oysters. Of course, if oysters are thoroughly cooked before eating, the chances of being infected with parasites or pathogens can be greatly reduced.

The transmission route of Vibrio cholerae is mainly through contaminated water sources or undercooked food such as seafood and vegetables. Crowded living and poor sanitation, especially public water sources, are important factors causing the outbreak.

Shellfish products such as norovirus oysters and raw fruits and vegetables are common foods that cause outbreaks. Water transmission can be caused by the pollution of other drinking water sources such as bottled water, municipal water supply and well water. There may be multiple transmission routes in an outbreak.

In addition, eating too much oysters will lead to heavy gastrointestinal burden, indigestion and stomach injury. This thing has a high cholesterol content, so it is best for people with three highs to stay away from it. Moreover, seafood generally belongs to hair, and eating too much does more harm than good. For your own health, it is recommended not to overeat.
