Do you know that there will be cross -pollution in the family kitchen?And it may be caused by your "hygiene" operation.Today, Ma Xiaochen, chief physician of the Nutrition and Food Health Center of the Beijing Centers for Disease Prevention and Control, came to reveal the secrets to everyone, how can bacteria occupy your kitchen step by step.
Family food poisoning, kitchen pollution is due to
Cross pollution refers to food processing, transportation and storageDuring the process, the spread of microorganisms, chemicals or other pollutants between different foods or between food and environment, or between different regions.
Cross -pollution is an important cause of food -oriented diseases. According to statistics from the World Health Organization, the occurrence of about one -third of the worlds food -oriented diseases is related to cross -pollution.Microbial cross -contamination in the kitchen is also an important cause of family food poisoning.Cross pollution in the kitchen is mainly caused by factors such as mixed raw, mixed food mixed food, tools and containers, and improper ingredients.
The chief physician of Ma Xiaochen takes the production of salad as an example. The raw chicken has a certain amount of bacteria on the surface. When you use a cutting board to deal with chicken, the bacteria transferred from the surface of the chicken to the cutting board, knife and tools and tools.Hand.With the same set of chopping boards and tools without washing your hands, the bacteria were transferred to the vegetable salad through the case board, tool and hand, and eventually achieved cross -pollution.
Many people do wrong
The truth.The so -called "raw" refers to the raw materials for making food, such as raw and poultry meat, eggs, and soil vegetables; "cooked" refers to food that can be eaten directly, including cooked meat, cooked dishes, cold dishes, salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads and salads.Fruits, vegetables, etc. used for raw food.The most basic principle of preventing cross -pollution is to ensure that raw food will not be exposed to instant or cooked food.However, Ma Xiaochen said that the separation of many families in life did not do it thoroughly, creating opportunities for bacteria to expand the site.
1) The two sides of the cutting board are not considered to be familiar with The cutting board, rag, etc. should be separated from the cooked food, there must be two sets, and it should be stored and stored for separation.Special reminder, if the front and back of a cutting board are used, it is not raw and cooked! 2) Dont be confused in order of handling the ingredients. The work table that has been treated with "raw food" must be cleaned with detergent.When using the same workbench to condition different ingredients, we should first regulate ingredients with lower pollution, such as food foods, and then conditioning ingredients with higher pollution, such as fresh meat and seafood. 3) Disinfection after raw food should be in place Keep the kitchen utensils and hands clean. After handling raw meat and its products, wash your hands, and wash your hands with soap and flowing water for at least 20 seconds. 4) The food placement in the refrigerator is particular In the refrigerator, the raw poultry meat and aquatic products should be sealed and stored, and they are placed under the cooked food or food to avoid cross -pollution.
Do these details of bacteria have nowhere to hide
Next, the chief physician Ma Xiaochen will share with you a few small details of "understand when you talk about, and do it as soon as you do".
1) The faucet directly rinse raw meat to spread the bacteria to spread it. Many people may be confused when they see this, because everyone is usually dealing with meatBefore, I have the habit of cleaning blood and bacteria by tap water before. I do n’t know that such operations will cause serious cross -pollution.Ma Xiaochen explained that when we opened the faucet and washing the meat, even if the water was small, there would still be water splashing.These splashing water flowers will spread the pathogenic microorganisms in raw meat to the nearby walls, countertops, sinks, kitchen knives, and even other foods to launch hidden food safety hazards.The correct way is to wash the meat in a basin that is connected to the water, and clean the water basin in time after washing the meat, thereby reducing the risk of cross -pollution due to meat washing. 2) The more wiping the rag "over -service", the more dirty to keep the kitchen clean, it is an important measure to prevent the kitchen from cross -pollution.Wipe the more dirty.The rag will adsorb bacteria during use, and it is difficult to completely squeeze the water inside after use, which makes them the ideal medium of microorganisms.Therefore, it is recommended that you disinfect or replace the rag regularly. 3) The seasoning tank that is not cleaned into a bacterial heating bed Everyone wipes the table, stove, pool, cutting board and other places when making cleaning, but I believe most of this place to mention most.People will ignore it, that is the seasoning tank.A study of the probability of cross -pollution on the surface of various kitchen on the surface of various kitchen shows that the most cross -pollution rate is the seasoning tank. 48%of the sample detected a tracer used to simulate pathogenic microorganisms.Therefore, do n’t forget to clean the surface of the seasoning tank we use every day when doing cleaning. When the seasoning is used up, it is necessary to take the opportunity to clean the seasoning tank.
