Secondly, do "six don't eat", don't eat cold food, unclean fruits and vegetables, don't eat spoiled food, don't eat meals without high temperature treatment, don't drink raw water and don't eat snacks.

Then, we should pay attention to identifying the quality of food from the food label. Choosing safe food is the first step to control the disease from mouth to mouth. 1, understand the characteristics of food poisoning.

the incubation period is short: generally, gastrointestinal symptoms: diarrhea, abdominal pain, and some accompanied by vomiting and fever occur within a few minutes to several hours after eating. 2. If you have the above symptoms, you should doubt whether you have food poisoning, go to the hospital in time and report to the teacher. 3. Prevent food poisoning and develop good hygiene habits.

. Talking about Hygiene and Health 1). Talking about Hygiene and Health In fact, hygiene must be paid attention to everywhere. On the roadside, on the street, in the alley, in the stalls of those vendors, you should never buy some food such as oil cakes and stinky tofu. Who knows what they are made of, they are prone to get sick and even cause symptoms such as diarrhea and dizziness. Wash your hands before and after meals, which is also a hygienic behavior.

When it comes to health, some people may say, "Eating too much makes you healthy!" In fact, health does not lie in eating more. You should exercise regularly, drink more water, eat regularly every day, go to bed on time and so on, so as to be healthy. I read in the newspaper that eating too much fruits and vegetables and taking more vitamins are good for your health.

Hygiene and health are closely linked. Poor hygiene not only makes your body easy to get sick, but sometimes even your precious eyes will be attacked.

When you come into contact with money, moldy books and other things, you should never rub your eyes, otherwise, the bacteria on your hands will get into your eyes, which will make you suffer from trachoma and lead to poor eyesight. In order to have a healthy body, we should develop good hygiene habits at ordinary times.

Good hygiene habits are not abstract concepts, but are expressed as little things in life. For example, to maintain personal cleanliness, clothes should be changed frequently, bathed frequently, and nails cut frequently; Wash your hands before and after meals; Clean the environment frequently; Take part in physical exercise properly to enhance your immunity.

( 2). Food Hygiene When eating hot pot, we should pay attention to the cold weather. People like to eat hot pot, but we should pay attention to the following hygiene habits: (1) Food should not be eaten too hot. Overheated food is easy to burn oral mucosa and esophagus, gastric mucosa and induce diseases of esophagus or stomach. (2) Too much food should not be left in the hot pot, so as not to cook the food for too long and lose the flavor and nutrition of the dishes.

(3) Food must be cooked before eating, so as not to be infected with parasite eggs or bacteria. 9, overeating hurts the body In daily life, some people like to enjoy large pieces of meat and large glasses of wine, until they are full and drunk, but they don't know that the hidden trouble is already in it.

Overeating exceeds the normal digestion of the spleen and stomach. First of all, it produces a feeling of fullness and fullness, which is prone to indigestion. Secondly, when a large number of high-protein foods are ingested for a long time, blood ammonia will increase greatly, which exceeds the ability of liver and kidney to process ammonia. Produce ammonia poisoning; What is more serious is that a large amount of ammonia accumulated in the blood will enter the brain tissue with the blood flow, poisoning the central nervous system, ranging from being groggy and confused all day long to sudden death after overeating.

A scientific diet is to eat well at breakfast, eat full at noon and eat little at dinner, and avoid overeating and drinking. 1. Beware of food poisoning in the refrigerator. As a kind of refrigerated food storage household equipment, the refrigerator brings a lot of convenience to people's daily life, but the refrigerator is not a safe.

generally speaking, the temperature in the freezer is-15~18℃, while it is only 2~8℃ in the normal greenhouse. Low temperature can inhibit most pathogenic bacteria, but it has little effect on psychrophilic and psychrophilic bacteria. Some bacteria can grow and reproduce below zero.

Therefore, the refrigerator can't inhibit all bacteria, and the food stored in the refrigerator can also go bad. 11. Raw and cooked foods and knives should be separated. Raw and cooked foods refer to the tools for making, holding and storing raw and cooked foods.

utensils such as chopping boards and knives should be separated and clearly marked, and raw and cooked foods should not be stored in the same refrigerator or cupboard. Raw and cooked food are not separated, and cooked food is easy to be polluted, causing intestinal diseases and parasitic diseases, which are harmful to health.

12. What does a balanced diet mean? The food should be varied and light, and the coarse grain flour and rice should be matched. Eat less fat and sweets and more vegetables and fruits. 13. Wash the wok in time to keep healthy. Some people do not clean the wok in time after cooking for the sake of convenience and convenience, and then fry the next dish, or mistakenly think that the wok is used every day without cleaning. In fact, it is very harmful to health, especially when processing protein and fatty dishes, it will form a pot scale containing carcinogens, and often eat a small amount of carcinogens, which will leave hidden dangers in the body.

Therefore, when cooking, you should clean a dish.
