Don't eat lunch for more than 2 hours, and try not to eat or drink at unprotected food stalls. Don't eat deformed, stale and discolored foods and foods with damaged and abnormal packaging (such as bulging cans), because such foods may go bad.

When buying food, check the food safety labels such as "production date" and "shelf life". Don't eat green beans, fresh day lilies, sprouted potatoes, wild mushrooms, moldy grains and eggs with broken eggshells.
