There are many watermelon bacteria overnight, can you not eat it?

As long as the new watermelon is stored properly, it can still be eaten after overnight. If you feel that watermelon can't be eaten, you must attach plastic wrap immediately after cutting, and then put it in the refrigerator and pay attention not to put it with raw meat and eggs. There are analysis of the total number of colonies of the colonies under the surface of 2cm samples under the surface layer of the watermelon that it is on the day and overnight refrigeration (16 hours overnight time in the experiment). The results showed no significant difference in the total number of colonies.This shows that low -temperature refrigeration can significantly delay or inhibit the growth of the bacteria of watermelon cutting surface. Overnight, watermelon does not have the problem of consumption safety caused by the total number of colonies, which can still be eaten with confidence.

新的西瓜只要贮藏得当，隔夜后仍然可以食用。如果觉得西瓜吃不完，切开后一定要立即附上保鲜膜密封，再放到冰箱冷藏室，注意别和生肉、鸡蛋放在一起。有研究对西瓜的新鲜切面、隔夜冷藏后切面和隔夜冷藏后切面表层下2cm样品的菌落总数进行了分析（实验中隔夜时间为16小时)，结果显示三者在菌落总数上无明显差异。这表明低温冷藏能明显延缓或者抑制西瓜切面细菌的生长，隔夜西瓜不存在菌落总数超标导致的食用安全性问题，还是可以放心吃的。
