    What is the point of separating the cutting board raw and cooked? For vegetables, fish, meat, chicken, duck, eggs, rice and other raw foods, from production to consumption, due to various factors, they are often contaminated by bacteria, viruses and parasitic eggs, and even fresh tomatoes that people think are relatively clean have been tested for E. coli, and some also contain typhoid bacillus.

    Dysentery bacillus, staphylococcus.

    roundworm eggs, etc. <>

    Separate storage of raw and cooked food means that raw and cooked food should not be stored separately in packaging containers, otherwise it is easy to breed bacteria, contaminate cooked food, and affect health. "Cooked" refers to something that can be eaten straight after being cut, such as mixing cucumbers and gravy; "Raw" refers to food that must be heated after cutting. The purpose of separating raw and cooked food is to prevent bacteria in raw food from infecting "cooked" food and causing food poisoning.

    Guo Yunchang, deputy director of the Food Disease Surveillance Department of the National Center for Food Safety Risk Assessment, said that this is the most effective and easy-to-learn foodborne disease avoidance in the world.

    measures. Lettuce, raw meat, and raw fish often contain bacteria, even pathogenic bacteria.

    Parasites and eggs. Basically, the bacteria in cooked and cooked foods have been killed. Cooked food can become contaminated if raw and cooked food are mixed, or if cooked food is placed in a container containing raw food, and cooked food is cut raw again with a knife and cutting board.

    If the virus is not killed in time, the virus can easily remain in the environment. Avoid using jet hand dryers, otherwise the virus can spread into the air. It is recommended to use disposable paper towels to wipe your hands. "Feces are transmitted orally to the sanitary vas deferens.

    Once excreted, it is likely to wake up the virus in the sewer or feces and then spread into the air. After using the bathroom, make sure to cover it before rinsing it and disinfect the bathroom, drains, and drains regularly. If water backflow and leakage are found, the hardness of the toilet or sewage should be strengthened.

    At the same time, disinfection should be carried out regularly. Conventional household cleaning and disinfecting products are effective in removing viruses from surfaces. Surfaces suspected of being contaminated with the virus can be disinfected with an alcohol-based product.

    Raw and cooked food should be cut separately, as the direct contact of the food, kitchen knives and cutting boards, when cutting raw food, bacteria and other bacteria in the food will remain on it, and lettuce also has more bacteria and parasite eggs. If it is later used to cut cooked food, bacteria will directly contaminate the cooked food with kitchen knives and cutting boards. Even if you blanch it with boiling water before use, the bacteria are often not completely destroyed.

    Therefore, to ensure food safety, you should have two kitchen knives and two cutting boards at home, and use them separately. And before cutting cooked food, it is safer to boil it in boiling water.

    2. Keep the cutting board clean After the cutting board is used, scrub it with a hard board brush and clean water to wash off the dirt along with the sawdust. If there is a fishy smell of fish, meat, etc., you can use salt-dissolved rice washing water or washing spirit to scrub, and then wash it with warm water. Do not scald it with boiling water, because the protein in the meat remains on the cutting board, which solidifies when it is hot and is not easy to wash.

    After washing, stand up to dry. After the cutting board is used for a period of time, you can use a kitchen knife to scrape the sawdust on the cutting board, or use a carpentry planer to plan, so that the dirt on the cutting board can be completely removed, and the cutting board can be kept flat and easy to use.

    3. The reason for separating raw and cooked food is an important cause of food poisoning in restaurants, collective canteens and families because livestock and poultry meat and aquatic products directly contaminate cooked meat and cold vegetables, or food refrigerated raw and cooked food and meat and vegetables are not distinguished. Because raw food carries many disease-causing bacteria or parasite eggs on it. According to the data, 30 of the pigs, cattle and mutton were produced; Among fruits and vegetables, 79 had intestinal bacteria such as E. coli, and 81 had roundworm eggs.

    In the processing of these foods, bacteria or parasite eggs will inevitably contaminate the utensils, and if these utensils are used to process and hold cooked food, then the bacteria and insect eggs will contaminate the cooked food, and people may develop food poisoning or parasitic diseases after eating. Raw and cooked food utensils, including kitchen knives, cutting boards, pots and baskets, and utensils, must be equipped with two sets, and be used separately according to raw and cooked.

    Some families do not prepare two sets of food utensils, but after processing and serving raw food, wash and scrub the utensils or pour boiling water to disinfect them, and then serve cooked food.

    Most families have the habit of sharing a cutting board.

    Do you know what the dangers of raw and cooked food are not separated?

    It is understood that pathogenic bacteria are the enemies that accompany human beings throughout their lives, one of which is called Salmonella, and the health hazards it will cause are: gastroenteritis, bacteremia, reactive arthritis or death. Statistics show that the number of cases of gastroenteritis caused by Salmonella is 93.8 million every year, and the number of deaths from infection is 10,000 people every year.

    Salmonella causes more than 1 million illnesses and nearly 400 deaths in the United States each year. In China, it is estimated that more than 9 million people fall ill and about 800 die every year. Most people with Salmonella infection present with gastroenteritis symptoms that get better on their own after a few days with no sequelae, so it doesn't look scary.

    However, the elderly, infants and young children and people with poor immunity may develop bacteremia and systemic infection, and once this happens, the case fatality rate can even be reached, so it is a health threat that cannot be ignored.

    A survey by an institution has found that the proportion of raw and cooked cutting boards in China is less than 1 3, and only half of the residents who are not separated from raw and cooked use detergent to clean cutting boards. It is estimated that if everyone separates raw and cooked cutting boards, the number of salmonella food poisoning people in China can be reduced by 2 million people every year.

    Kitchen knives and cutting boards, which are direct contact with food, are left with bacteria and other bacteria in the food when cutting raw food, and lettuce also has more bacteria and parasite eggs. If it is used to cut cooked food later, bacteria will directly contaminate cooked food with kitchen knives and cutting boards, and raw food often carries many bacteria and parasite eggs, if they are not separated during processing and storage, such as: cutting cooked food with a knife that has cut raw food; If the container containing raw food is not washed and disinfected to hold cooked food, the bacteria and parasite eggs on the raw food will be contaminated to the cooked food again, and a large number of cooked foods will multiply, endangering human health.

    We propose: For the sake of people's health, each family should prepare two cutting boards, raw and cooked separately!

    Some families do not pay attention to the separation of raw and cooked food when cutting vegetables, and often cut cooked food directly after cutting raw food, which is unscientific and can easily cause diseases.

    Because there are a large number of bacteria and parasites attached to fresh food, these harmful substances will be contaminated on the cutting board and kitchen knife when cutting, if the cutting board and kitchen knife are not fully disinfected, and continue to cut cooked food, these harmful substances can easily contaminate the food. If the cooked food is contaminated, the germs and parasites on it will directly enter the human body without hindrance, which is very easy to cause lesions.

    Some people will scald the cutting board with boiling water to disinfect after cutting fresh food, which will have a certain effect, but boiling water can not kill most bacteria in a short time, or will make bacterial parasites remain. Therefore, it is best to separate raw and cooked food, i.e. prepare a set of cutting boards and kitchen knives for raw and cooked food.

    A small cutting board is not only a necessity in the kitchen, but also closely related to our health. In our previous concept, a cutting board is enough, raw food, cooked food, vegetables and fruits are all operated on the same cutting board, but in fact, this operation is very "suffocating", and if you are not careful, you will "get sick from the mouth". People take food as the sky, and everyone should not have a fluke mentality in eating, and only by doing a good job of sorting the cutting board can we eat safely and healthily.

    Raw foods such as fresh meat and vegetables may have some bacteria and parasite eggs that need to be cooked before they can be eaten, while cooked foods can basically be eaten as is. If the same cutting board is used for raw and cooked food, we can easily cause the cooked food to be contaminated after cutting the raw food, so that when we eat the cooked food again, we may have gastrointestinal discomfort and affect our gastrointestinal health.

    For the health problems of cutting boards, some people choose to clean them in time after cutting raw food, or use boiling water to disinfect them, but this can only play a simple cleaning role, and it is almost ineffective for bacteria and molds, such as aflatoxin, staphylococcus, E. coli, etc., boiling water can not kill most bacteria in a short time, and these harmful substances will continue to remain.

    In addition, not only the cutting board, but also the matching knives also need to be separated from raw and cooked. Like cutting boards, kitchen knives can carry bacteria or parasite eggs, which can contaminate cooked food and affect your health.

    For the sake of our health and the health of our families, the safest and most effective way is to do a good job of sorting the cutting boards from the beginning. Considering that multiple cutting boards may be inconvenient to store, after careful consideration and multi-party comparison, I chose this set of knife cutting board sterilizer from Mofei, which has three cutting boards and three knives, one set of raw food, cooked food, vegetables and fruits, and the special knife board is safe and hygienic, and it is very convenient to install it when storing.

    There is another reason why I chose this set of cutting boards, I have always felt that the cleaning problem is very tricky, and I am always worried that bacteria and mold will not be clean. Usually rinse the cutting board and put it in the box, press the switch to disinfect, and use it with more peace of mind.

    1. Raw and cooked cutting boards are mostly used separately in life, generally speaking, the surface color of the cutting board used for cutting meat is darker, and there are more knife marks, and many people like to use plastic cutting boards for cutting vegetables or fruits.

    2. When we use plastic cutting boards, we must avoid high temperatures, because sorghum temperature will make the plastic cutting boards soften and deteriorate.

    3. Generally speaking, many people prepare two cutting boards, so that the meat and the fruits and vegetables should be used separately, so as to avoid the parasites on the meat from getting on the cooked food.

    4. As the cutting board becomes longer in use, a large number of bacteria will grow on it, so it must be cleaned regularly to achieve dry oak and careful hygiene.

    If the cutting boards of raw and cooked meat are not separated, pathogenic bacteria such as Salmonella in raw meat can contaminate cooked meat through vectors such as cutting boards and kitchen knives. Most bacteria are destroyed by heating at high temperatures, so cooked meat can be eaten without heat, and salmonella will follow into the body, causing food poisoning. Salmonella can multiply in the intestine and enter the bloodstream to induce an immune response, causing nausea, vomiting, abdominal pain and diarrhea.

    In severe cases, pathogenic bacteria can invade the bloodstream and cause sepsis, systemic infection, and even life-threatening. How to do a good job of separating meat and vegetables? 1. Prepare 2 3 kitchen knives and cutting boards at home At least 2 3 kitchen knives and cutting boards at home, use them separately according to the type of food you cut, and use different utensils for handling raw food, cooked food and fruits.

    2. Choose the right cutting board material The common cutting board materials in life are divided into solid wood, bamboo and plastic, different cutting boards have different advantages and disadvantages, and the cutting board should be selected according to the type of food. Solid wood cutting boards are the most common in daily life, thick and strong, but not easy to dry, easy to mold when placed in a humid environment for a long time, and will hide dirt and bacteria after a long time. If you usually chop a lot when cooking, you should choose this kind of cutting board, and clean and sterilize it after use; Bamboo cutting boards are lightweight and dry, making them less prone to mold.

    Remember to clean the cutting board after use, and wash the cutting board thoroughly with detergent in time after use, and then place it in a dry and ventilated place to dry, which can avoid bacterial breeding and multiplication.
