Oysters are also called oysters, which is another name for oysters. China is a big producer of oysters, and 70%-80% of the global output is in China. Besides raw food, barbecue, cooking and soup making, it is also used to produce oyster sauce and other by-products.

The most classic way to eat oysters is of course raw. Some people can't put it down, others refuse. The root cause is that raw food is unsafe. In recent years, a product called "purified oyster" has gradually appeared on the market. Merchants claim that only purified oysters are real oysters.

Extended data:

Oyster is a bivalve shellfish, which belongs to filter-feeding animals, that is, algae and zooplankton in seawater are collected and eaten like a sieve. One of the problems brought by this lifestyle is that it will also enrich the dirty things in seawater, such as sediments and microplastics. Studies have found that there may be dozens of microplastics species in the digestive tract of an oyster.

In addition, it will also suck pathogenic microorganisms in seawater, such as Vibrio parahaemolyticus, Vibrio vulnificus and norovirus. Sometimes it will be contaminated by other pathogenic bacteria, such as salmonella, during transportation, sales and production.
