(1) Pay attention to drinking water hygiene. Generally speaking, you can't drink raw water. Boiled water and sterilized tap water are the most ideal drinking water for the journey, followed by mountain spring and deep well water. Rivers, ponds and lakes cannot be drunk raw. When there is no qualified water to drink, you can use melons and fruits instead of water.
(2) melons and fruits must be washed or peeled before they can be eaten. You must peel the fruit when you eat it. Melons and fruits are not only polluted by pesticides, but also by germs or parasites during picking and selling.
(3) Treat every meal with caution and never go hungry. High-end restaurants can generally eat safely, food stalls can be eaten selectively, and stalls or vendors (carts) should not eat. Although there are a lot of hungry situations during the trip, the food of the street vendors can't be touched. If you are hungry, you are playing with your life.
(4) Learn to identify whether the hygiene of restaurants is qualified. The general standards of qualification should be: having a hygiene license, clean water source, disinfection equipment, fresh food raw materials, no mosquitoes and flies, dust-proof equipment, clean surrounding environment, no contact between the payee and food, and keeping a considerable distance between money and food.
(5) eating and drinking in vehicles, ships or planes. When riding, because there is no exercise condition, the digestion process of food is prolonged and the speed is slow. If you don't control your diet, it will inevitably increase the burden on the gastrointestinal tract and cause gastrointestinal discomfort.
