White paper is used to package food. Many foods are painted with "white paper" to make them look cleaner. In fact, in order to make white paper "white", many manufacturers often use bleach in the production process. When bleach comes into contact with food, it will cause a series of chemical reactions, produce some harmful substances and easily pollute food. Wipe the dishes with toilet paper. The sampling results of the national fruit quality inspection department show that many kinds of toilet paper are not disinfected or not completely disinfected, and contain a lot of bacteria, which are easy to attach to the wiped objects. Only high-grade sanitary napkins that have undergone strict disinfection can meet the hygiene standards.
Put the plastic sheets on the table. Although the plastic sheets on the table are beautiful, they are easy to accumulate dust and bacteria. Some plastic sheets are made of toxic vinyl chloride resin. Tableware and food exposed to plastic sheets for a long time will be polluted by harmful substances, which will lead to many unnecessary diseases and affect health. Cover the food with gauze. Although flies do not directly land on food, they will stay on the gauze cover, leaving eggs with bacteria. These eggs easily fall from the gauze holes and pollute the food.
Sterilize dishes with wine. Some people often wipe dishes and chopsticks with white wine, thinking that this can achieve the purpose of disinfection. At present, it is not clear that the alcohol content used for medical disinfection is 75%, while the alcohol content of ordinary liquor is below 56%. Therefore, wiping dishes and chopsticks with white wine can not achieve the purpose of disinfection. Dig out the rotten part of the fruit before eating. Some people eat fruit, and when they meet the rotten part of the fruit, they will cut off the rotten part and eat it again, thinking it is hygienic. In fact, even if the rotten part of the fruit is peeled off, the remaining part has been transferred to bacterial metabolites through juice, and even microorganisms have begun to multiply, including molds that can mutate human cells and cause cancer. Therefore, even if the fruit is only partially rotten, it is best to throw it away.
