Not long ago, there was a hot search, the topic was "raw meat can not be directly washed at home", the reading volume reached 440 million, more than 40 media released, and nearly 70000 related microblogs, which can be said to have attracted a wave of traffic. Under this topic, netizens started the "muddle headed" and "stick playing" mode, and some felt that such caution made people anxious about food; Another netizen jokingly said, "If you don't wash it in my home, why don't you wash it in your home?" As a "popular science" topic, it is true that we have grasped the "traffic password", which is simple. In fact, there are some bacteria on the raw meat. When it is washed with water, the bacteria will spread when the water splashes on the pool and the stove. This statement is correct in itself, but interpreting this "correct information" as "you can't wash raw meat directly at home" is a bit of anxiety. As for the relationship between washing raw meat and food safety, the following points can be combined to form a "correct understanding": 1. From the perspective of bacteria, it is not necessary to wash raw meat. Of course, there are some bacteria on the raw meat, but cooked meat will kill it. Moreover, the efficiency of removing bacteria by washing with water is also very low. 2. People wash raw meat not to remove bacteria, but to wash blood and water. Or even, it's just a psychological feeling that you should wash it. 3. Rinsing raw meat and splashing water will indeed increase the spread of bacteria. However, in fact, in most people's kitchens, there may be more bacteria on the stove and sink than on the meat. Increasing that point or avoiding that point has little impact. 4. For kitchen hygiene, what needs to be done is to clean and keep dry frequently, eliminate the hidden danger of bacteria from various sources, rather than avoid "bacterial pollution from a specific source". 5. For kitchen food safety, "separating raw food from cooked food" and "fully heating" are the ultimate weapons. In short, for "washing raw meat with water", it is "unnecessary" or "can not be washed", or at most, "it is better not to wash directly" or "it can be washed in a water basin to avoid water splashing". The word "can't" seems to be said as if direct washing would do much harm. Finally, let's say "cold knowledge": take your mobile phone to test it, and it is probably full of bacteria. However, this "correct message" does not mean that you should disinfect your mobile phone every day, but that "germs are everywhere, and you don't need to hear about them as if they are the enemy".
