In daily life, these habits need to be changed:
Eggs are not washed before being cracked
When cooking many people don't wash eggs before breaking them into a pan or bowl. An egg goes through several processes from the nest to the market, and its shell is already contaminated with a large number of bacteria. If you don't wash the egg before cracking it for cooking, the bacteria will flow into the pan with the egg liquid. Therefore, when breaking eggs for cooking, you must first rinse the eggs clean with tap water.
The heart of a Chinese cabbage is eaten without washing
Many people think that the heart of a Chinese cabbage, after peeling off layer after layer, is very clean and doesn't need washing. In fact, it takes 2-3 months for a Chinese cabbage to grow and form its heart. During this time, it needs to be fertilized and treated for pests many times, and with air pollution, bacteria have long taken root in the heart of the cabbage. Therefore, the heart of the Chinese cabbage cannot be eaten as soon as it is peeled, but must be soaked in salt water for more than 30 minutes, and washed repeatedly before eating.
