Some people say that "overnight watermelon, 8400 bacteria in one bite", and indeed eating overnight watermelon caused gastroenteritis hospitalization. Then, can the cut watermelon, peach, apple and other fruits, as well as the opened yogurt, milk, ice cream and other drinks, be eaten and drunk the next day? Wang Xin, a public dietitian in the city, suggested that whether you can continue to eat cut fruits or Kaifeng drinks overnight depends on whether the storage method and storage conditions are appropriate, and whether the food is contaminated by harmful bacteria. If you can't finish eating after opening it, seal it and put it in the refrigerator for refrigeration. It will be safer to eat it as soon as possible the next day. The saying that "watermelon eats 8400 bacteria in one bite overnight" is widely spread. This actually comes from the experiment of a TV program, cutting watermelon with different tools, and detecting bacteria the next day. The most is "8400 colonies", so there is the sentence "eat 8400 bacteria in one bite". In fact, this experiment is to show that watermelon should be cut with special tools to remind everyone to pay attention to food safety. When cutting raw food and directly imported food, the knife and cutting board should be used separately. In fact, the living environment is full of bacteria, and there are more bacteria in the air, but most of them are harmless. The high total number of bacteria does not mean that the food is unsanitary. The key depends on whether the food is polluted by harmful bacteria. The whole watermelon you buy home is best to use a special knife and chopping board for cutting fruit. If you can't eat all the watermelon, wrap it with plastic wrap and put it in the refrigerator for refrigeration. Watermelon with hygienic operation and good storage can be safely eaten after being refrigerated in the refrigerator. In the same way, cut peaches, apples and other fruits, which can't be eaten, should be sealed with plastic wrap and put into the refrigerator for refrigeration, and it's also possible to take them out the next day. Because the cut fruit is easy to oxidize and rot when exposed to high temperature and air, if the fruit has rotted, it is best to throw it all away. Even if the rotten part of the fruit is dug out and then eaten, it may not be safe, and other parts may have been contaminated by bacteria. Yogurt and milk are rich in protein. It is easy to deteriorate due to infection with harmful bacteria when it is placed in a high temperature environment in summer after being opened. Whether it's yogurt or milk, if you can't finish it after opening it, be sure to seal it and put it in the refrigerator for refrigeration, and finish it within 24 hours. If the boxed and barreled ice cream can't be eaten at one time, it should also be sealed and then put into the refrigerator for freezing. When eating boxed or barreled ice cream, you can dig out a few spoons and eat them in a bowl instead of holding a bucket or box. You should also pay attention to reducing the time for the ice cream to leave the refrigerator every time you eat it, and don't take out the whole box to thaw and freeze it repeatedly.
