The French eat oysters. Seafood is the most famous French dish in the world, and the most commendable is the oyster commonly known as "oyster". As early as the Middle Ages, oysters were the favorite food of the French.

17th century, emphasizing luxury and ostentation, oysters have more ways to eat, but gourmets always advocate raw food. Oyster is a kind of marine life, with the reputation of "milk in the sea", which is rich in protein and trace elements necessary for human body, especially raw.

If served with dry white wine, oysters will taste more delicious. However, oysters belong to raw seafood after all. Without reliable and good health protection, eating raw food will cause a series of diseases such as high fever and abdominal pain.

France, which has a long habit of eating oysters, rarely hears that eating oysters causes diseases, which is naturally related to the strict food hygiene management in France. Aubert Day is a famous seafood restaurant near Mayotte, Paris, with a history of 80 years.

The supply of oysters alone accounts for 40% of restaurant turnover. The front of the restaurant consists of several huge freezers filled with all kinds of seafood.

The director of the pavement, Gontier, told the reporter that in order to ensure that the oysters served on the table are fresh and clean, several processes such as purification and preservation should be done in advance. French oysters are big, thin and juicy.

However, the oysters salvaged must first be "purified" in the mariculture pond. After about a week, the oysters spit out all the silt and remove the unclean attachments on the surface before they can be certified.

Japanese restaurants in Aubert consume an average of three or four hundred kilograms of oysters every day. According to the regulations, the oysters needed by the restaurant should be ordered from the place of origin or wholesale market on the first day and delivered to the restaurant around 6 am that day.

Oysters are very delicate and need high temperature and humidity. Once they leave the culture tank, they must be refrigerated. Clean refrigerated trucks should also be used to transport oysters, and pollution should be avoided during loading and transportation, and the transportation time should be as short as possible.

Oysters are usually refrigerated at a constant temperature of 4 to 5 degrees Celsius. If it is high, bacteria will breed, causing oyster meat to rot. If it is low, it will freeze or freeze oysters. Health and quarantine departments regularly send people to conduct sampling inspection on the production, transportation, sales and restaurant handling of oysters.

The inspection contents include the bacterial content of oyster meat, the cleanliness of fresh-keeping equipment and the standardization of packaging. Under the guidance of Gontiere, the reporter saw that every small box containing oysters in aubert Japanese restaurant was marked with product name, grade, weight, quantity, license number, quarantine result, packaging date and place, and the name and contact number of the manufacturer.

According to the standard, a box of oysters should weigh 15 kg. The oysters transported to the restaurant can be kept in the freezer for up to 6 days, and cannot be turned over or mixed with other foods.

There are four waiters who use Gontiere to treat oysters. You must wear red overalls to work, which is in sharp contrast to the white or black overalls of other waiters.

The difference of clothing color has a good supervisory function, so that guests who come to dinner can see at a glance how Gontiere treats each oyster. Anyone who has tasted oysters knows that oysters are delicious and difficult to open.

In fact, the tools used to open oysters in restaurants are very simple, just a sharp knife and clever cooperation with both hands. Every restaurant waiter who deals with oysters has to go through a period of skill training and relevant knowledge and legal study, such as the identification of oyster species, the nutritional value and hygiene standards of oysters, the quality guarantee conditions and deadlines, and the operating procedures and skills of opening oysters.

Gontiere said that he and his colleagues should have a routine physical examination every year, the work clothes should be changed and cleaned regularly, and the knives should be disinfected regularly. Hand cleaning is of course the most critical, and it must be washed with clean water constantly.

Still, when you open the oyster, you can't touch the meat with your fingers. If this set of operating rules is violated, oyster meat will be polluted, diners will be unhappy and restaurants will be seriously affected.
