4. What aspects should be paid attention to in food safety?

First, choose and eat safe food.

When buying and consuming food, we should pay attention to choosing restaurants and food stores with valid hygiene licenses. When buying packaged food and bulk food, we should check whether the labels indicate the factory name, address, production date and shelf life. Pay attention to whether the fly-proof and dust-proof facilities are complete, and whether the storage conditions and storage containers meet the hygiene requirements when buying cooked braised dishes and cold dishes. Second, food must be thoroughly cooked before eating, especially poultry, meat and milk. When heating, ensure that the temperature of all parts of the food reaches at least 70℃.

Green beans and soybean milk should be thoroughly heated and cooked, because they contain hemagglutinin and saponin respectively. Third, avoid cross-contamination of raw and cooked food: when cooking, food tools such as knives and chopping boards should be separated from the containers containing food, and be careful not to mix raw and cooked food when storing food in the refrigerator.

4. Reheat the cooked food thoroughly: If the food is stored in the refrigerator every other day or overnight, it must be completely reheated before eating, which can kill the microorganisms that multiply during storage. However, if cooked food is found to be spoiled, it should be discarded, because some toxins produced by microorganisms cannot be eliminated by heating. 5. Keep the kitchen clean: the tools and utensils used to prepare food must be kept clean, the sink should be cleaned and disinfected regularly, and the dishcloth in contact with kitchen utensils should be disinfected and dried every day. Tableware should be kept clean after cleaning and disinfection.

6. Avoid insects such as flies and cockroaches from touching food: The best protection measure is to store food in a closed container to prevent the above pests from bringing pathogenic microorganisms into food. Seven, consumers traveling abroad, due to physical fatigue, immunity and digestive function will decline.
